- a lighting device 10 which includes a first component 11, a second component 12 (see particularly Figure 2) connected to the first component, and a base member 13 joined to the lower end of the second component 12 for supporting the device 10 on a ground surface 80 as will be referred to below.
- the first and second components 11, 12 are elongate, being substantially cylindrical in shape, with a common longitudinal axis 14 (see figure 2).
- the first component 11 includes a light housing, generally designated 15, which includes a lens assembly 16, a cap 17 at the top thereof, and an intermediate body portion 18 connected to the lower end of the light housing.
- the lens assembly 16 and the intermediate body portion 18 each have two halves which are sonically welded together.
- the cap 17 is fixed to the light housing 15 by a compression fit and/or is sonically welded to the light housing 15, thus helping to keep the light housing 15 as an effectively integral unit.
- the intermediate body portion 18 is illustrated as being a separate part to the light housing 15, but joined thereto.
- the intermediate body portion 18 and the light housing 15 can be integrally formed.
- the second component 12 includes a battery housing 20. As shown in Figure 2, the battery housing 20 has, at its lowest end, a male thread 21, and the base member 13 has a female thread 22 which receives the male thread to secure the base member to the battery housing 20.
- Shown held in the battery housing 20 is a D-size dry cell or battery 23.
- the battery housing 20, at its upper end, has a spring contact 24 for engaging a negative terminal 25 of the dry cell or battery 23.
- a wire (not shown) connects the spring contact 24 to a printed circuit board 26.
- An LED light source 27, supported on an LED support 28, is electrically connected to the printed circuit board 26. The LED 27 extends from the printed circuit board 26 so that its diode projects into the light housing 15.
- the battery housing 20 also includes, at its upper end, an elongated switch-contact column 30 which terminates in a flat contact surface 31, for engaging a switch 32 which is mounted on the underside of the printed circuit board 26, the switch 32 and printed circuit board 26 forming part of the first component 11.
- the switch 32 is a button switch of a type which closes by being pressed, and which then opens when pressed again.
- Beneath the contact surface 31, around the column 30, is a flange 33 for providing a bearing surface against which a compression spring 34 can press.
- the battery housing 20 has a cylindrical outer wall 35 which includes annular surfaces 36, 37, 38 and 39 which constitute bearing surfaces against, and along which, parts of the intermediate body portion 18 can bear, and slide, respectively. It will therefore be appreciated that the outer wall 35 is received telescopically within intermediate body portion 18.
- the bearing surfaces 37 and 39 are recessed relative to the surfaces 36 and 38, and the intermediate body portion 18 has radially inwardly directed flanges 40 and 41 which project into these recesses.
- the steps from the non-recessed surfaces 36 and 38 to the recessed surfaces 37 and 39 define an upper shoulder 42 and a lower shoulder 43, between which the flange 40 can move.
- the upper shoulder 42 limits movement of the intermediate body portion
- the base member 13 supports a further electrical contact 44 within the battery housing
- the threaded connection between the threads 22 of the base member 13 and those 21 of the battery housing 20 helps to prevent ingress of water into the battery housing.
- the battery housing 20 is stepped radially outwards, to define a further shoulder 46.
- This shoulder 46 is disposed in an opposed relationship to the lowermost edge 47 of the intermediate body portion 18, which thus also constitutes a shoulder, and will be referred to as such, below.
- a zone, generally designated 48, of the lighting device 10 in the form of a groove, which is referred to further, below.
- the upper part of the intermediate body portion 18 includes radially inwardly projecting shoulders 49 which support the printed circuit board 26.
- the printed circuit board 26 is held against the shoulders 49 by means of the shaped LED support 28, which helps to prevent the LED from moving laterally relative to the printed circuit board.
- the light housing 15, towards its bottom end, has a radially outwardly projecting shoulder 50, which extends into a groove 51 in the intermediate body portion 18, for locating the light housing relative to the intermediate body portion.
- An internal wall 52 surrounds the LED support 28 and fixes this support and the printed circuit board 26 in position as illustrated in Figure 2.
- a locator or index means (not illustrated) is provided, either on the printed circuit board 26, or on the LED support 28, so that when the device 10 is assembled, the switch 32 is aligned with the contact column 30 of the battery housing 20.
- the upper portion of the light housing 15, which serves as part of the outer wall of this housing, is constituted by the lens assembly 16.
- the lens assembly 16 is made from a transparent or translucent material
- the internal surface 54 can have a frosted finish to help diffuse light over the cylindrical external surface 55 of the lens assembly.
- the external surface 55 may or may not include striations or lenticules 56, which are generally annular, and extend along the outer circumference of the lens assembly 16.
- the inner surfaces of the upper wall (not shown) and lower wall 52 of the light housing 15 are reflective.
- any light emitted by the LED 27 will reflect off these surfaces, which facilitates the transmission of light through the lens assembly 16.
- the base member 13 as illustrated in Figures 3 and 6 includes a heavy, metal weighting element 59 for contributing to the weight of the base member 13, to facilitate stable support of the base member 13 and hence the lighting device 10, on a ground surface, as will be referred to below.
- the lighting device 10 further includes a restraint element 60 (see Figures 1 and 4), which is configured to be connected, in the groove, to the zone 48 between the shoulders 46 and 47, for obstructing the shoulders and thus preventing the relative movement of the first component 11 towards the second component 12 (downwards as shown in Figures 1 and 2 when the second component is on the ground), for a purpose as will be described below.
- a restraint element 60 see Figures 1 and 4
- the lighting device 10 further includes a restraint element 60 (see Figures 1 and 4), which is configured to be connected, in the groove, to the zone 48 between the shoulders 46 and 47, for obstructing the shoulders and thus preventing the relative movement of the first component 11 towards the second component 12 (downwards as shown in Figures 1 and 2 when the second component is on the ground), for a purpose as will be described below.
- the restraint element 60 is detachable from the zone 48, and from the lighting device
- the element 60 is elongate, and curved substantially into a C-shape, such that its two opposite ends 61 are disposed opposed to each other, and spaced from each other to form a gap
- the element 60 which is resiliently deformable, has a radially inner surface
- the element 60 has a substantially oblong cross-section.
- the element 60 has a radially inner flange portion 66 extending substantially the length of the element 60, and a radially outwardly projecting web portion 67 extending along the radially outer surface of the flange portion 66, for strengthening the flange portion 66.
- the base member 13 includes a cylindrical holder 68 which is accessible through an annular aperture 69 in the bottom of the base member 13 as shown in Figures 3 and 6, and which is sized and shaped such that the element 60, when it is not disposed in the groove of the zone 48, can be engaged therewith, and supported thereon as shown in this figure.
- Figures 7 and 8 there is shown a restraint element 60 according to another embodiment.
- the element 60 has a similar, additional element 60.1 connected to it by a hinge portion 70 to form a composite element, designated 71.
- the additional element 60.1 is for engagement with an additional lighting device (see Figure 9), designated 10.1, which is identical to the lighting device 10, as will be described below.
- each composite element 71, 171 constitutes a means for interconnecting the two lighting devices 10 and 10.1.
- the hinge portion 70 is configured to permit rotational movement of the restraint elements 60 and 60.1 relative to each other, as indicated by the arrow 72 in Figure 10, between the opened-out condition shown in Figure 7 and a juxtaposed condition as shown in Figure 11.
- the restraint elements 60 and 60.1 are superposed on each other.
- the composite element 71 can be configured to allow its restraint element 60 to fit within its restraint element 60.1 when the composite element 71 is in the juxtaposed condition.
- the hinge portion 70 can be longer than that shown in Figure 10.
- the composite element 71 can be configured such that the uppermost surface of the restraint element 60, as shown in Figure 10, is aligned with the lowermost surface of the restraint element 60.1 as shown in this figure, with the hinge portion interconnecting these surfaces.
- the restraint element 60 can be held as a press fit in the restraint element 60.1 when the composite element 71 is in the juxtaposed condition.
- the recesses 74 of the lighting device 10 are for accommodating the end (upper) extremity 75.1 of the additional lighting device 10.1, while the recesses 74.1 of the additional device 10.1 are for accommodating the end (upper) extremity 75 of the lighting device 10.
- the cylindrical holder 68 is configured for holding the composite element 71, in its juxtaposed condition, when it is not being used to connect the two lighting devices 10, 10.1 together.
- the composite element 71 includes more than two restraint elements. Configurations of such embodiments are shown diagrammatically in Figures 12 and 13, and also shown in Figure 14. In these Figures, the additional restraint elements are designated 60.2, while in Figures 12 and 13, the tabs interconnecting the restraint elements are designated 70.2.
- the composite element 71 can be provided with restraint elements 60 and 60.2 having different size relationships to one another, depending on the specific shape and orientation of the lighting device 10 and additional lighting devices to be interconnected. Accordingly, with reference to Figure 12, the diameter of the element 60 can be smaller than the diameters of the elements 60.2.
- the restraint element 60 can engage the zone 48 of the lighting device 10, while each element 60.2 engages the lens assembly 16 of a respective additional lighting device.
- the diameter of the element 60 can be the larger diameter for engaging the lens assembly of the lighting device 10, while the diameters of the elements 60.2 are smaller, for engaging the respective zones (corresponding to the zone 48) of the additional lighting devices.
- two such composite elements 71 and 171, one with the restraint element 60 being smaller than the restraint elements 60.2, and the other with the restraint element 60 being larger, can be used in conjunction with each other, as a set of composite elements 71, 171, for interconnecting three lighting devices corresponding to the lighting device 10.
- the first component 11 of each lighting device in question may be provided with a circumferential groove corresponding in size to the groove of the zone 48, so that the restraint elements 60 and 60.2 can have the same diameters as each other.
- the composite element includes the three restraint elements 60, 60.2 interconnected to one another by a central web 76, and securement means, in the form of a strap 77, for anchoring the composite element and lighting devices (not shown in Figure 14) which are interconnected by it.
- an electrical circuit 78 forming part of the lighting device 10.
- the circuit 78 includes the spring contact 24 and the further contact 44, these being connected to the dry cell power source 23.
- the circuit 78 includes the switch 32, and the LED 27 which, in a preferred embodiment, is a white LED.
- the circuit 78 also includes a transformer 79 which is used to step up the voltage from the 1.5 volt output of the power source 23 to 3.6 volts, which is required to illuminate the white LED 27. Closure of the switch 32, when the power source 23 is connected to the contacts 24 and 44, closes the circuit 78 and illuminates the LED 27. Opening of the switch 32 opens the circuit 78, extinguishing the LED 27.
- the lighting device 10 as shown in Figure 1 can be stowed, for example, in the boot (trunk) of a motor vehicle (not shown).
- the device 10 can be used, when necessary, such as in an emergency situation, or during a break-down of the vehicle, to provide a portable means of lighting an area, such as the area surrounding the vehicle.
- the base member 13 is configured to support the device 10 in an upright orientation on the ground surface 80 when it is level, with the second component 12 above the base member and the first component 11 above the second component and terminating at the upper extremity 75.
- the portions 73 of the base member 13 which extend laterally beyond the outer wall of the intermediate body portion 18 provide lateral stability.
- the weighting element 59 provides stability to the device 10 to assist it in remaining upright, even during windy conditions.
- the restraint element 60 is then removed from the groove of the zone 48.
- the ear portion 65 facilitates the gripping of the element 60 by a user, and hence assists in the removal thereof, from the groove.
- the gap 62 is smaller than the diameter of the device 10 at the zone 48 (i.e. the floor of the groove), the resilience of the element allows it to be deformed during removal, and hence permits the gap to be widened, so as to move over the zone to clear it.
- the element 60 Once the element 60 has been removed in this way, it can be conveniently located on the holder 68, to prevent it from becoming lost. It will be understood that the restraint element 60, prior to being removed from the zone
- the first component 11 can be moved towards the second component 12, by pressing downwards on the cap 17 in the direction of the arrow 81 in Figure 1.
- the light housing 15 and intermediate body portion 18 move relative to the battery housing 20, against the bias of the spring 34.
- the contact-column 30 presses against the switch 32, thus closing it, and hence also closing the circuit 78, and illuminating the LED 27, the light of which is transmitted through the lens assembly 16.
- the user repeats this procedure so that the contact-column 30 again presses against the switch 32, thus opening it, and hence also opening the circuit 78, thereby extinguishing the LED 27.
- the restraint element 60 To re-engage the restraint element 60 with the zone 48, it is merely forced into place. As a result of the flaring of its ends 61 at the positions 64, the ends are angled to facilitate engagement of the element 60 with the zone 48. As the element 60 is pressed onto the zone 48, the flared ends 61 ride over the zone causing the gap 62 to widen, and allowing the element to snap-engage with the zone within the groove, so as to be held in place once again.
- the restraint element 60 when so engaged, can be used to prevent relative movement of the first component 11 towards the second component 12 to prevent the inadvertent illumination of the LED 27 due to movement of the device 10 or due to other objects colliding with it, when it is being stowed in the vehicle, as this can result in the power source 23 being drained and the device thus not being of any use when needed.
- the restraint element 60 can be used to minimise the chance of the LED 27 being inadvertently switched off when it is in use, for example as a result of the device 10 falling over. In this case, the element 60 can be re-engaged with the zone 48 after the LED 27 has been illuminated in use, rather than being placed on the holder 68.
- one or more additional devices such as the device 10.1 as shown in Figure 9 can be stowed for use in a vehicle, and held together with the device 10 with a composite element such as the elements 71 and 171 as described above.
- the composite element 71 is used during stowing, to prevent inadvertent illumination of the LED 27 of the device 10, while the other composite element 171 is used to prevent inadvertent illumination of the LED of the other device 10.1.
- the composite element 71 can be held, in its juxtaposed condition, on the holder 68 of the device 10 while the other composite element 171 can be held, also in its juxtaposed condition, on the holder 68.1 of the other device 10.1.
- the composite 71, 171 elements thus not only prevent inadvertent illumination of the LEDs of the devices 10, 10.1, but also keeps the device together.
- the strap 77 can be used, for example in a vehicle, during stowage of a device 10 and additional devices which are interconnected by this element, to secure the devices to a fixed surface to prevent the devices from moving around.
- FIG 16 Illustrated in Figure 16 is a lighting device 10.1 which is similar to the device 10 of previous figures.
- the device 10.1 differs from the device 10 in that the base 13 terminates in a generally circular member 59.1, which can include a weight formed therewith or attached thereto. It will be noted that the device 10.1 does not include a cylindrical holder 68 as is present on the device 10.
- FIG. 17 to 19 Illustrated in Figures 17 to 19 is a modified lighting device 110, which is similar to the device 10, with like parts being like numbered.
- the device 110 differs from the device 10 in that the base member 13 includes a circular wall 115 which provides a sealed end to the bottom of the battery housing 20.
- the base member 13 has an external thread 21 while the base of the battery housing has an internal thread 22.
- the passage 116 has a circular aperture 118 on its left side and another circular aperture 119 on its right.
- a generally cylindrical slide member or bolt 112 is positioned for slidable movement within the passage 116, and as shown in Figure 19, protrudes through the left side aperture 118 so as to position its left end between the shoulders 46 & 47 on the left side, preventing the lighting device 110 being switched on or off.
- the slidable bolt 112 includes a left side shoulder 120 to prevent the bolt 112 sliding too far to the left. To switch the lighting 110 on or off, the bolt 112 is slid to and through the right side aperture 119, which will position the bolt 112 beneath a recess 111 as in Figure 17.
- the recess 111 and the fact that the left end of the bolt 112 is no longer keeping the shoulders 46 and 47 apart, will allow the first component 11 to move towards the combined second component 12 and base 13. As the first component 11 moves towards the combined second component and base 13, the right side of the bolt 112 will relatively move into the recess 111, so as to activate the on/off switch 32.
- the bolt 112 has a right side shoulder 121 which will limit the travel in the right hand direction of the bolt 112.
- a bias member 114 which is a spring with a downwardly extending N shaped portion 122.
- the bolt 112 has an inverted N portion 113 between the shoulders 120 and 121.
- the portions 113 and 122 interact to provide an over centre biasing mechanism whereby, once the bolt 112 is pushed just over halfway between its limits of travel, it will be biased to the other side. By this means, the bolt 112 will only protrude through either the left side aperture 118 or right side aperture 119.
- the device 110 thus has a restraint in the form of the bolt 112, which is not detached from the lighting device 110, and does not detach from the zone 48.
- FIG. 20 Illustrated in Figure 20 is a modified lighting device 210, which is similar to the device 10. Accordingly like parts have been like numbered.
- the device 210 differs from the device 10 in that the restraint 60 is linked by a lanyard or member 211, which will facilitate the removal of the restraint 60 from the zone 48, but keep the restraint 60 on or connected to the device 210. In this way the restraint 60 is detachable from the zone 48, but not the device 210.
- the lanyard 211 can be formed integrally with base 13 and restraint 60, or it can be made separately and joined to the restraint 60 and base 13.
