DESCRIPTION OF THE PREFERRED EMBODTME~T
A bus light system 10 is adapted to be connected at the upper portion of an end of a passenger bus 12. The passenger bus 12 is 25 typically a school bus such that when the bus 12 stops to unload and load children, the traffic is required to stop in response to the bus light system 10.
The bus light system lo includes a plurality of indicator assemblies 16 connected at the upper section of the passenger bus 12. In . general, a pair of indicator assemblies 16 are ~ 2 1 78709 located at each end of the bus 12 adj acent each outer 6ide of the bus 12. Each of the indicator a6semblies 16 are similar in design and ~y ~Ly.
Therefore, only one indicator assembly 16 is 5 described.
The indicator assembly 16 includes a lighted display 18. The lighted display 18 includes at least f irst and second light element lO 20, 22 for separately illuminating first and second display sections 24, 26 of the display 18, respectively. The first and second sections 24, 26 include f irst and second display word messages indicated thereon and associated with the first and 15 second light elements 20, 22, respectively. The first word message of the first display section 24 indicates a slowing-to-stop condition and the 6econd word message of the second display section 26 indicates a stop condition. The lighted display 20 18 also includes a third display light element 28 for illuminating a third section 30 of the display 18 with a third word message wherein the f irst and third light elements f lash alternately in the slowing-to-stop condition. The lighted display 18 25 includes a fourth light element 32 for; l lllmin~ting a fourth display section of the display 18 with a fourth word message wherein the second and fourth light element 22, 32 flash alternately in the stop condition .
In the pref erred embodiment, the word message of the first display section 24 comprises the word CAUTION, and word mes~age of the second ~ 21 787~9 display section 26 includes the word STOP, and the word mes8age of the third display section 30 comprises the word STOPPING, and the word message of the fourth display 6ection 34 comprises the 5 words DO NOT PASS. Furthermore, the word message of the fourth display section 34 includes a hexagon geometric shape 36 about the word STOP, as is typical for a stop sign designation. Each of the first, second, third and fourth light elements 20, 22, 28, 32 and display sections 24, 26, 30, 34, respectively, are separately located and positioned from one another.
The fourth display 34 comprising the 15 hexagonal shape 3 6 with the word STOP therein is located on the outer side of the display 18 (~ith respect to placement of a pair of assemblies 16 connected on each end of a bus). The word messages CAI~TION, DO NOT PASS, STOPPING are located 20 sequentially from top to bottom on the second or inner side of the display 18. The first 24 and third 30 display sections are horizontally spaced from one another on the lighted display 18. The second 26 and fourth 34 display sections are 25 vertically spaced from one another on the lighted display 18.
The first and third display sections 24, 30 light illuminate the respective word messages 30 amber or yellow in color, whereas the second and fourth sections 26, 34 ill1lm;n~te red in color. In operation, during the slowing-to-stop condition, the word messages CAUTION ~nd STOPPING are -~ ~1 78709 alternately; l lllm;nAted. Once the bus 12 has come to a stop for unloading and loading, the word messages STOP and DO NOT PASS are alternately illuminated in each of the indicator assemblies 16.
5 Therefore, within each assembly 16, two display sections are alternately illuminated and flashed at a time, either the red sections 26, 34 or the yellow sections 24, 30.
The indicator assembly 16 includes a housing 40 haYing a front side 42 with side walls 44 establishing a cavity 46 behind the front side 42. An integral lens 48 extends between the first 24, second 26, third 30 and fourth 34 display 15 sections forming at least a part of the front side 42 and secured with the housing 40.
There are two embodiments of the indicator assembly 16, 16' wherein common 20 components include similar reference numerals differing in embodiments by a primed numerals. In both ~orhn~;r?~ts, the lens 48, 48' is translucent to allow illumination by the light elements 20, 22, 28, 32. The display 18, 18' is effectively the 25 same, only differing by structure between the embodiments .
In the first embodiment 16, the housing 40 and lens 48 are is injection molded as an 30 integral, single unit of a clear smoked black plastic material. The location of the letters and geometric design 3 6 in each word message are of a thinner molded material 43 whil~ the rn--;n~r of ~ 8709 ' the front face 42 is thicker to provide isolated illumination. The housing 40 is an integral single molded plastic shape which can be secured and permanently and installed on a bus 12. The cavity 5 46 may then be sealed from atmosphere with the light elements therein by a back panel 50. The housing 40 includes divider ribs 52 which extend from the front side 42 into the cavity 46 to isolate illumination of the light elements from 10 each of those associated with different sections 24, 26, 30, 34. In this ~mho~l;r~rlt, the light elements 20, 22, 28, 32 are comprised of a plurality of LEDs which are secured to a circuit board 51 and forming each of the word messages by 15 strings of LEDs. The LEDs are colored red or yellow depending on the section 24, 26, 30, 34 within which they are positioned. The LEDs are placed behind the thinner sections 43 of the front face 42 to clearly illuminate the word messages 20 therethrough with a black background. A power conductor 53 may extend through the circuit board 51 and back panel 50 to independently supply power to each of the light elements 20, 22, 28, 32'.
Alternatively, a multi-colored lens 48 may be molded so that either a yellow or red thinner sections 43 are molded over each of the respective word messages. The background may be molded with black with the red or yellow insert molded therein. Clear LEDs may then be positioned therebehind. Also, clear incandescent bulbs may be used in place of the LEDs.
-~ 21 7B7~9 P-320 lo - The second embodiment 16 ' (Figure 5) includes the housing 40 ' molded separate from the lens 48 ' and thereafter secured to one another.
The display lens 48 ' is formed having a planar 5 front surface which includes raised lens surfaces 54 protruding therefrom. The display lens 48 ' may lternatively be comprised of a generally box shaped member including side and a back panel to provide a chamber for receiving and sealing the lO light elements therein. The front side 42 ' of the housing 40 ' includes openings 56 formed therein to receive the raised lens surfaces 54 therethrough.
The display lens 48 ' is positioned within the cavity 46' of the housing 40'. The raised surfaces 15 54 extend through the front side 42 ' projecting through the openings 56 external the housing 40 ' .
The lens 48 ' may be secured within the housing 40 ' by suitable fasteners. In this embodiment 16 ', the housing 40 ' may be injection molded of a black or 20 opa~ue material with the openings 56 provided therein. The display lens 48 ' may be molded of a clear material, which may include colored raised letters or clear, as similar with the first i mh~fl;r~nts 16. Either LEDs or other lighting 25 bulbs may be used, clear or colored depending on coloring of the lens 48 ' . Chamber divisions may also be used.
The bus light system 10 may include a 30 switch 62 actuated by the bus driver to cause the f lashing of the red stop word message display sections 26, 34 and separate flashing of the yellow display sections 24, 28 and respective word messages. ~he driver would typically use the switch 62 to power the yellow lights in a f lashing manner when it is approaching a stop for the loading or unloading. When the bus 12 comes to a 5 complete stop, the red stop light sections 26, 34 are switched by the switch 62 to alternately flash to before the door of the bus 12 is opened. This switching function and control thereof may be accomplished by the switch 62, or other type of 10 software controller.
Each of the indicator assembly 16 are connected by the power connectors 53 to the switch 62 and in turn to a power supply such as of the 15 bus, as commonly known in the art. The user or driver of the bus 12 can switch between of f, caution, and stop, which will selectively power light the respective word or sections and provide the f lashing alternating indication .
The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is lntended to be in the nature of words of 25 description rather than of limitation.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to 30 be understood that within the scope of the appended claims, the invention may be practiced otherwise than ~s specifically described.
other non-vehicle illuminated signs with indicia thereon have used neon lights, LEDs, 0 fluorescent bulbs., etc. Such lights ;~ m1n~te a section of the sign to display indicia, such as words or symbols. Exemplary thereof is United states Patent Number 4,8gl,896, issued January 9l 1990 in the name of Boren which discloses a simulated neon sign wherein a housing includes raised letters.

The cavity 5 46 may then be sealed from atmosphere with the light elements therein by a back panel 50. The housing 40 includes divider ribs 52 which extend from the front side 42 into the cavity 46 to isolate illumination of the light elements from 10 each of those associated with different sections 24, 26, 30, 34. In this ~mho~l;r~rlt, the light elements 20, 22, 28, 32 are comprised of a plurality of LEDs which are secured to a circuit board 51 and forming each of the word messages by 15 strings of LEDs. The LEDs are colored red or yellow depending on the section 24, 26, 30, 34 within which they are positioned. The LEDs are placed behind the thinner sections 43 of the front face 42 to clearly illuminate the word messages 20 therethrough with a black background. A power conductor 53 may extend through the circuit board 51 and back panel 50 to independently supply power to each of the light elements 20, 22, 28, 32'.
Alternatively, a multi-colored lens 48 may be molded so that either a yellow or red thinner sections 43 are molded over each of the respective word messages. The background may be molded with black with the red or yellow insert molded therein. Clear LEDs may then be positioned therebehind. Also, clear incandescent bulbs may be used in place of the LEDs.
-~ 21 7B7~9 P-320 lo - The second embodiment 16 ' (Figure 5) includes the housing 40 ' molded separate from the lens 48 ' and thereafter secured to one another.
The display lens 48 ' is formed having a planar 5 front surface which includes raised lens surfaces 54 protruding therefrom. The display lens 48 ' may lternatively be comprised of a generally box shaped member including side and a back panel to provide a chamber for receiving and sealing the lO light elements therein. The front side 42 ' of the housing 40 ' includes openings 56 formed therein to receive the raised lens surfaces 54 therethrough.
The display lens 48 ' is positioned within the cavity 46' of the housing 40'. The raised surfaces 15 54 extend through the front side 42 ' projecting through the openings 56 external the housing 40 ' .
The lens 48 ' may be secured within the housing 40 ' by suitable fasteners. In this embodiment 16 ', the housing 40 ' may be injection molded of a black or 20 opa~ue material with the openings 56 provided therein. The display lens 48 ' may be molded of a clear material, which may include colored raised letters or clear, as similar with the first i mh~fl;r~nts 16. Either LEDs or other lighting 25 bulbs may be used, clear or colored depending on coloring of the lens 48 ' . Chamber divisions may also be used.
The bus light system 10 may include a 30 switch 62 actuated by the bus driver to cause the f lashing of the red stop word message display sections 26, 34 and separate flashing of the yellow display sections 24, 28 and respective word messages. ~he driver would typically use the switch 62 to power the yellow lights in a f lashing manner when it is approaching a stop for the loading or unloading. When the bus 12 comes to a 5 complete stop, the red stop light sections 26, 34 are switched by the switch 62 to alternately flash to before the door of the bus 12 is opened. This switching function and control thereof may be accomplished by the switch 62, or other type of 10 software controller.
Each of the indicator assembly 16 are connected by the power connectors 53 to the switch 62 and in turn to a power supply such as of the 15 bus, as commonly known in the art. The user or driver of the bus 12 can switch between of f, caution, and stop, which will selectively power light the respective word or sections and provide the f lashing alternating indication .
The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is lntended to be in the nature of words of 25 description rather than of limitation.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to 30 be understood that within the scope of the appended claims, the invention may be practiced otherwise than ~s specifically described.
