The utility model relates to an opposite-irradiation LED (light-emitting diode) backlight module, belonging to the technical field of LEDs. The opposite-irradiation LED backlight module consists of white light SMD (surface mount device) LED light sources, a light guide panel, a reflecting surface film, a diffusing surface film and PCBs (printed circuit boards). The opposite-irradiation LED backlight module is characterized in that the white light SMD LED light sources are fixedly connected onto the PCBs, the front surface and the back surface of the light guide panel are respectively covered by the reflecting surface film and the diffusing surface film, the PCBs are fixedly connected onto a group of two opposite sides of the light guide panel, the white light SMD LED light sources are welded on the PCB, the white light SMD LED light sources are serially combined through the PCBs and are connected with a power supply, and two groups of pins are arranged on the light guide panel, wherein one group of pins are used as common positive voltage control pins for all rows and the other group of pins are used as cathode control pins. The opposite-irradiation LED backlight module has the advantages that the light consistency of light-emitting planes is good, the light is evenly emitted, the heat dissipation effect is good, the service life of backlight is prolonged and the luminous efficiency is improved.
Description
Technical field
The utility model relates to the LED technical field, is specifically related to a kind of LED-backlit module of penetrating mutually.
Background technology
The LED-backlit module is owing to low energy consumption, demonstration color and luster are various widely-used by industrial automation and Lighting Industry.The LED-backlit module that occurs in the market mainly is to adopt single face light source backlight technology and straight cutting light emitting diode to make the back light technology; Because the single face backlight shines from a direction; Light intensity changes with the area of LGP, produces the light phenomenon that falls from the sky or outer space, and causes the guiding plane non-uniform light.Especially at white light and blue light as the backlight application field, effect is poorer, its traditional backlight pattern requires the field in the high-performance backlight luminescence, can not satisfy people's demand.
The utility model content
The utility model technical problem to be solved is to provide a kind of good heat dissipation effect, prolongs backlight service life, carry do luminous efficiency penetrate the LED-backlit module mutually.
The utility model technical problem to be solved adopts following technical scheme to realize.
A kind of LED-backlit module of penetrating mutually; Constitute by white light paster LED light source, light guide panel, reflective facial mask, diffusion facial mask, pcb board five parts; It is characterized in that: described white light paster LED light source is fixed on the pcb board; Said light guide panel positive and negative is covered with reflective facial mask and diffusion facial mask respectively, and said pcb board is fixed in one group of light guide panel mutually on two limits, and described white light paster LED light source is welded on the pcb board; Said white light paster LED light source is connected with power supply through pcb board parallel connection combination; Said light guide panel is provided with two groups of pins, and wherein one group pin is as the public positive voltage control pin of each row, and the pin of another group is controlled pin as negative pole.
The rectangular structure of said light guide panel.
Described positive voltage control pin and negative pole control pin are separately fixed at the light guide panel two bottom sides.
The beneficial effect of the utility model is: the utility model luminous flat light consistency is good, luminous evenly, can reach every square centimeter of aberration less than 1/1000, the integrated combination of module; Automatic production be can realize, minimizing assembly cost and material cost, integrated modular are convenient to install; Increase reliability of products, adopt PCB Surface Mount SMD LED technology, good heat dissipation effect; Prolong backlight service life, carry and do luminous efficiency.
