Abstract
The utility model discloses a high-brightness yellow green LED (Light-Emitting Diode) backlight source. The high-brightness yellow green LED backlight source comprises a light guide plate, a white high-brightness LED is arranged on one side of the light guide plate, first reflective films are arranged on the other three sides of the light guide plate, a second reflective film is arranged at the back side of the light guide plate, and a yellow PET (polyethylene terephthalate) diffusion film is arranged at the front side of the light guide plate. For the high-brightness yellow green LED backlight source, when the light guide plate and the reflective films are assembled, the white backlight source can lead the LED to achieve a yellower or greener backlight color effect through the matching of the PET yellow film under the situation that the light of the whole backlight source is not influenced. With the high-brightness yellow green LED backlight source, the common yellow green light intensity can be improved by three to four times, and the high-brightness yellow green LED backlight source is widely applied on electronic electrical appliance modules.
Description
Technical field
The utility model relates to the backlight field, concrete relates to a kind of high bright orange green LED backlight.
Background technology
Under the situation that the technology of the brightness of backlight yellow green LED lamp at present reaches its maturity; Brightness can be accomplished 150MCD basically; But along with the demand and the variation in market, the brightness all the time of high bright orange green colored backlights is not high, and the demand in market has been satisfied not in this brightness at all; Along with the fast development of backlight technology, the whole luminous intensity of backlight and performance are with increasingly high.
The utility model content
For overcoming the deficiency of prior art, the utility model aims to provide a kind of high bright orange green LED backlight that can effectively improve the color of White LED backlight.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of high bright orange green LED backlight; It comprises a LGP, and a side of said LGP is provided with white high-brightness LED, and other three sides are respectively arranged with first reflectance coating; The back side of said LGP is provided with second reflectance coating, and the front of said LGP is provided with yellow PET diffusion barrier.
Compared with prior art, the utlity model has following beneficial effect:
The high bright orange green LED backlight of the utility model is when LGP and reflectance coating assembling, and the backlight of white will pass through the yellow diaphragm of PET and cooperate, and can make LED under the situation that does not influence entire backlight source light, obtain more yellow or greener backlight color effect.The utility model can rise to 3-4 times of common yellowish green light intensity, is widely used on the electronic apparatus module.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment and the conjunction with figs. detailed description of the utility model.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model.
Label declaration among the figure: 1, white high-brightness LED, 2, second reflectance coating, 3, LGP, 4, first reflectance coating, 5, yellow PET diffusion barrier.
The specific embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to shown in Figure 1; A kind of high bright orange green LED backlight; It comprises a LGP 3, and a side of said LGP 3 is provided with white high-brightness LED 1, and other three sides are respectively arranged with first reflectance coating 4; The back side of said LGP 3 is provided with second reflectance coating 2, and the front of said LGP 3 is provided with yellow PET diffusion barrier 5.
The utility model is applicable to the side backlight that shading region is little, brightness is high.White high-brightness LED 1 lamp is evenly distributed on LGP 3 surfaces through LGP with light, and the PET diffusion barrier 5 with yellow is attached to LGP 3 light-emitting areas again, realizes the low high brightness yellow green backlight of cost.
The preferred case study on implementation that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
