Abstract
The utility model provides a kind of new LED-backlit module, including light guide plate and it is placed in the LED light source of the light guide plate plane of incidence, it is characterized in that, the LED light source is divided into several light source groups along the light guide plate plane of incidence, and the light source group is made up of three LED or at least four of rectangular arrangement in the LED of fan-shaped arrangement.LED light source of the present utility model is arranged using rectangular arrangement or in sector, on the basis of illumination effect is constant, effectively reduces the usage quantity of LED, reduces product cost.
Description
Technical field
The utility model is related to LED technology field, and in particular to a kind of new LED-backlit module.
Background technology
Backlight module is an important component of liquid crystal display device, and liquid crystal display is special using the physics of liquid crystal
Sex work, be powered when, liquid crystal arrangement in order, light easily by；During no power, arrangement then becomes chaotic, and light is not easy
Pass through.But liquid crystal will not light in itself, it needs an additional backlight lighting device --- backlight module, and its function is exactly
The area source of high brightness, high uniformity is provided for liquid crystal display.The development of liquid crystal display industry pulled backlight module and its
The market demand of associated component, by development in recent years, the backlight module of Ultrathin high-brightness is shared in liquid crystal display panel
Cost ratio improve constantly, especially the backlight module of LED light source, is even more paid attention to by many transnational enterprises.With
The continuous lifting of LED luminous efficiencies, the range of application of LED-backlit module constantly expands, and traditional LED-backlit module is logical due to light
Amount is not enough and LED heat-sinking capabilities are poor, is often only used in the LCDs of the small sizes such as mobile phone and digital camera.With
World LED manufacturers and develop the highlighted LED suitable for LCD TV backlight so that LED-backlit module rapid osmotic to liquid
Brilliant TV domain.
Existing LED-backlit module is traditional side entrance back module, is to enter light in side whole piece long, and its LED is parallel
In the light guide plate plane of incidence, and it is uniformly distributed along the light guide plate plane of incidence, the LED quantity for using is more, relatively costly.
Utility model content
In order to solve the above technical problems, the utility model uses new LED-backlit module, it is possible to decrease the use number of LED
Amount, concrete technical scheme is as follows：
A kind of new LED-backlit module, including light guide plate and the LED light source of the light guide plate plane of incidence is placed in, its feature
It is that the LED light source is divided into several light source groups along the light guide plate plane of incidence, the light source group is by three LED of rectangular arrangement
Or at least four constituted in the LED of fan-shaped arrangement.
The light source groups that the LED of three rectangular arrangements is constituted, the LED light-emitting areas of its both sides perpendicular to the light guide plate plane of incidence,
The LED light-emitting areas at middle part are parallel to the light guide plate plane of incidence.
The light guide plate plane of incidence is located at the short side of light guide plate or side long.
From above technical scheme, LED light source of the present utility model is arranged using rectangular arrangement or in sector, luminous
On the basis of effect is constant, the usage quantity of LED is effectively reduced, reduce product cost.
Brief description of the drawings
Fig. 1 is to use the structural representation that three LED are a light source group in the utility model；
Fig. 2 is to use the structural representation that five LED are a light source group in the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, it is new this practicality is described in detail
Before the technical scheme of each embodiment of type, involved noun and term are explained, in this manual, title is identical
Or label identical part represents similar or identical structure, and it is only limitted to the purpose illustrated.
LED-backlit module includes light guide plate 1 and is placed in the LED light source of the light guide plate plane of incidence 2, and the LED light source is along guide-lighting
The plate plane of incidence is divided into several light source groups 3.
Embodiment 1：
The light source group 3 is made up of the high-capacity LED of three rectangular arrangements, and the LED light-emitting areas of its both sides are perpendicular to leading
The tabula rasa plane of incidence, the LED light-emitting areas at middle part parallel to the light guide plate plane of incidence, as shown in Figure 1.
Traditional common LED backlight module, it is assumed that use 36 LEDs, single power 0.18W, general power 6.48W
The utility model uses high-capacity LED instead, and from 3 LED of 2.16W, because the luminous efficiency of LED, brightness is basic
It is directly proportional to power, the adjustment arranged by the site of light guide plate can reach the illumination effect of traditional whole piece LED light source.
Embodiment 2：
The light source group 3 is made up of five LED in fan-shaped arrangement, and reference picture 2 can equally use four, six LEDs
Fan-shaped arrangement is done to reach same effect.
The above implementation method is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the guarantor that claims of the present utility model determine
In the range of shield.
