Abstract

The invention discloses a backlight structure of an LED lamp. The backlight structure comprises a white light LED lamp plate (1) and a colored LED lamp plate (2). White light LED lamps (3) are distributed on the white light LED lamp plate (1). Colored LED lamps (4) are distributed on the colored LED lamp plate (2). The thickness of the white light LED lamp plate (1) is the height difference of the colored LED lamps (4) and the white light LED lamps (3). Receding holes (5) are formed in the white light LED lamp plate (1) at intervals. The colored LED lamps (4) pass through the receding holes (5) from the back face of the white light LED lamp plate (1). Compared with the prior art, the backlight structure of the LED lamp achieves light-out face equal height of the two kinds of LED lamps, system light efficiency is improved, the backlight structure is simple in structure, mounting and fixing can be achieved conveniently, and the backlight structure is suitable for backlight structures of various LED products.

Description

A kind of backing structure of LED
Technical field
What the present invention relates to is a kind of LED technical field, in particular a kind of backing structure of LED.
Background technology
In LED-backlit design, often adopt the backlight mode of white light LEDs and color LED interval layout, white light LEDs is as main light emitting source, and color LED carries out spectrally compensating, by regulating the luminous ratio of the red, green, blue of color lamp LED, blend the spectrum meeting required chromaticity coordinates.
At present, general method for designing is interval layout two kinds of LED on same lamp plate, a kind of LED backing structure such as shown in accompanying drawing 3, comprises white LED lamp 8, color LED lamp 9 and PCB lamp board 10, and described white LED lamp 8 and color LED lamp 9 are spaced in PCB lamp board 10.But general color LED lamp is owing to encapsulating the chip of multiple different glow color, volume is comparatively large, especially at thickness direction much larger than white LED lamp.Therefore after two kinds of lamp welding, exiting surface height is different, and it is comparatively far away that white LED lamp exiting surface distance light guide plate enters light face, influential system light efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of backing structure of LED, to solve in existing LED lamp structure, white LED lamp is less because of thickness, installs the problem that rear distance light guide plate far causes system light efficiency rate to decline.
The present invention is achieved by the following technical solutions:
A kind of backing structure of LED, comprise white light LEDs lamp plate 1 and color LED lamp plate 2, described white light LEDs lamp plate 1 is furnished with white LED lamp 3, described color LED lamp plate 2 is furnished with color LED lamp 4, the thickness of described white light LEDs lamp plate 1 is the difference in height of color LED lamp 4 and white LED lamp 3, described white light LEDs lamp plate 1 is also interval with the resigning hole 5 passed through for color LED lamp 4, color LED lamp 4 passes through this resigning hole 5 from the back side of white light LEDs lamp plate 1, fit to the cloth lamp face of color LED lamp plate 2 and the back side of white light LEDs lamp plate 1, like this, the thickness of white light LEDs lamp plate 1 compensate for the difference in height of two kinds of lamps, ensure that the light face of two kinds of lamps at grade.
The cloth lamp face of described color LED lamp plate 2 is bonding by bond plies 6 with the back side of white light LEDs lamp plate 1; Bond plies 6 has the characteristic of high heat conduction and insulation, and there is flexibility, compressibility, docile property, strong viscosity, adaptive temperature scope is large, irregular surface can be filled up, energy close and firm ground laminating thermal source device, thermal impedance is little, white light LEDs lamp plate 1 and color LED lamp plate 2 is bonded by this bond plies 6, do not affect the thermal diffusivity of product, extend the service life of product.
The cloth lamp face of described white light LEDs lamp plate 1 is also equipped with diffusive reflective film 7, and diffusive reflective film 7 can realize the object of being carried out by the light source that LED produces reflecting, thus effectively improves LED light source utilization rate, reduces the loss of light LED light source and consumes, economize energy.
The size of described resigning hole 5 slightly larger than the size of color LED lamp 4, to ensure that color LED lamp 4 passes freely through resigning hole 5.
The present invention has the following advantages compared to existing technology: the backing structure that the invention provides a kind of LED, and the exiting surface that this backing structure achieves white LED lamp and color LED lamp is contour, improves system light efficiency rate; Meanwhile, the structure of this backing structure is simple, can realize easily installing and fix, be applicable in the backing structure of various LED product.

Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment 1
The backing structure of a kind of LED that the present embodiment provides, there is the structure as shown in accompanying drawing 1 ~ 2, comprise white light LEDs lamp plate 1 and color LED lamp plate 2, described white light LEDs lamp plate 1 is furnished with white LED lamp 3, described color LED lamp plate 2 is furnished with color LED lamp 4, wherein:
The thickness of described white light LEDs lamp plate 1 is the difference in height of color LED lamp 4 and white LED lamp 3;
Described white light LEDs lamp plate 1 is interval with the resigning hole 5 consistent with color LED lamp 4 layout, and the size of described resigning hole 5, slightly larger than color LED lamp 4, is passed through for color LED lamp 4; During installation, last layer bond plies 6 is coated with in the cloth lamp face of the back side of described white light LEDs lamp plate 1 or color LED lamp plate 2, described color LED lamp 4 is passed through described resigning hole 5 from the back side of white light LEDs lamp plate 1, and the cloth lamp face to color LED lamp plate 2 is mutually bonding with the back side of white light LEDs lamp plate 1;
The cloth lamp face of described white light LEDs lamp plate 1 is also equipped with one deck diffusive reflective film 7, and diffusive reflective film 7 can realize the object of being carried out by the light source that LED produces reflecting, thus effectively improves LED light source utilization rate, reduces the loss of light LED light source and consumes, economize energy.
This backing structure utilizes the thickness of white light LEDs lamp plate 1 to make up the difference in height of two kinds of lamps, and the light face that ensure that two kinds of lamps at grade, improves system light efficiency rate.
