Abstract
The invention discloses a high-brightness yellow-green LED (light-emitting diode) backlight source which comprises a light guide plate, wherein high-brightness white LEDs are arranged on one side of the light guide plate; first reflecting films are arranged on the other three sides of the light guide plate respectively; a second reflecting film is arranged on the back surface of the light guide plate; and a yellow PET (polyethylene glycol terephthalate) diffusion film is arranged on the front surface of the light guide plate. According to the high-brightness yellow-green LED backlight source, a white backlight source is matched with the yellow PET diffusion film during the course of assembling the light guide plate and the reflecting films, so that more yellow or more green backlight color effects can be achieved by the LEDs under the condition that light rays of the whole backlight source are not affected; the common yellow-green light intensity can be increased by 3-4 times; and the high-brightness yellow-green LED backlight source is widely applied to electronic and electric modules.
Description
Technical field
The present invention relates to the backlight field, be specifically related to a kind of highlighted yellow green LED-backlit source.
Background technology
In the situation that the technology of the at present brightness of backlight yellow green LED lamp reaches its maturity, brightness can be accomplished 150MCD substantially, but demand and variation along with market, the all the time brightness backlight of highlighted yellow green is not high, the demand in market is not satisfied in this brightness at all, along with the fast development of back light source technique, Integral luminous intensity and the performance of backlight will be more and more higher.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention aims to provide a kind of highlighted yellow green LED-backlit source that can effectively improve the color of White LED backlight.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of highlighted yellow green LED-backlit source, it comprises a LGP, and a side of described LGP is provided with white high-brightness LED, and other three sides are respectively arranged with the first reflectance coating, the back side of described LGP is provided with the second reflectance coating, and the front of described LGP is provided with yellow PET diffusion barrier.
Compared with prior art, the present invention has following beneficial effect:
Highlighted yellow green LED-backlit of the present invention source is when LGP and reflectance coating assembling, and the backlight of white will cooperate through the yellow diaphragm of PET, can make LED obtain more yellow or greener backlight color effect in the situation that does not affect whole backlight light.The present invention 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 technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and cooperate accompanying drawing to describe in detail.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Number in the figure explanation: 1, white high-brightness LED, the 2, second reflectance coating, 3, LGP, the 4, first reflectance coating, 5, yellow PET diffusion barrier.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Referring to shown in Figure 1, a kind of highlighted yellow green LED-backlit source, it comprises a LGP 3, one side of described LGP 3 is provided with white high-brightness LED 1, other three sides are respectively arranged with the first reflectance coating 4, the back side of described LGP 3 is provided with the second reflectance coating 2, and the front of described LGP 3 is provided with yellow PET diffusion barrier 5.
The present invention 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 look backlight of cost.
The above only is preferred case study on implementation of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
