Abstract

The utility model discloses a novel reflector plate structure, which comprises a reflector plate body, wherein a first protruding bar parallel to LED (Light-emitting Diode) light bars is formed at a part of an inner bottom face, which corresponds to a middle position between two adjacent LED light bars, of the reflector plate body; and the maximum height H1 of the first protruding bar is less than mixed light height H. According to the novel reflector plate structure and a backlight module thereof, the protruding structure is formed on the inner bottom face of the reflector plate body, so that the transmission direction of light is changed, the lbrightness of LEDs or between the LED light bars are reinforced, the uniformity of a whole backlight picture is promoted, the used quantity of the LEDs can be reduced, and the cost is reduced.

Description

A kind of new type reflection chip architecture and backlight module thereof

Technical field

The utility model relates to a kind of reflector plate structure and backlight module thereof.

Background technology

As shown in Figures 1 to 4, existing direct-light type LED backlight module, by backboard 4, LED lamp bar 2, reflector plate, support column 5, diffuser plate 6, diaphragm 7, and the fixed structure of diaphragm forms.LED lamp bar 2 is comprised of PCB substrate 23, LED 21 and the lens 22 that are fixed on LED 21 tops, and LED lamp bar 2 is fixed on backboard 4 medial surfaces equably.Reflector plate is comprised of four hypotenuses and even horizontal bottom for being a groove structure, and corresponding LED position, reflector plate bottom surface is done holes reflector plate is fixed on the lamp bar pcb board 23.This kind backlight design; the diffusion of scioptics 22; the spot light of LED is become uniform area source; in order to reach the even of picture; eliminate the LED lamp shadow, usually can increase the arranging density of LED, perhaps increase thickness backlight; so can increase cost backlight and power consumption, and be unfavorable for the thin design of product.

Summary of the invention

The utility model purpose is: a kind of new type reflection chip architecture and backlight module thereof are provided, it is by forming raised structures at reflector plate body inner bottom surface, change the transmission direction of light, brightness between reinforcement LED or the LED lamp bar is to reach the uniformity that reduces LED and use a number, the whole picture backlight of lifting, the purpose that reduces cost.

The technical solution of the utility model is: a kind of new type reflection chip architecture, comprise the reflector plate body, place, centre position between the corresponding adjacent two LED lamp bars of the inner bottom surface of described reflector plate body is formed with first protuberant bar parallel with LED lamp bar, the maximum height H1 of described the first protuberant bar＜mixed light height H.

One of further technical scheme: the place, centre position on corresponding each the LED lamp bar of the inner bottom surface of described reflector plate body between adjacent two LED is formed with projection, the maximum height H2 of described projection＜mixed light height H.

Two of further technical scheme: the inner bottom surface of described reflector plate body is formed with some parallel interval settings, is arranged vertically the second protuberant bar with the first protuberant bar, described the second protuberant bar lays respectively at place, the centre position between adjacent two LED on the LED lamp bar, the maximum height H3 of described the second protuberant bar＜mixed light height H.

Another purpose of the present utility model is: a kind of backlight module is provided, comprises reflector plate, described reflector plate adopts reflector plate described above.

The utility model has the advantages that: the utility model is by forming raised structures at reflector plate body inner bottom surface, change the transmission direction of light, brightness between reinforcement LED or the LED lamp bar, and then promote the uniformity of whole picture backlight can reduce LED simultaneously and uses a number, reduce cost.
