Description
[technical field]
The utility model relates to a kind of light guide plate and LED lighting, and is particularly a kind of with the light guide plate of diffusion layer and the LED lighting with this light guide plate.
[background technology]
Light guide plate is to utilize the acryl of optical grade/PC sheet material, then with having high reflectivity and the hitech materials of extinction not, stamps light guiding points in the acryl sheet material bottom surface of optical grade with the UV screen printing technology.The light that utilizes optical grade acryl sheet material to draw to send from the lamp that is positioned at side face of plate material is in the stop on optical grade acryl sheet material surface, when light is mapped to each light guiding points, reflected light can toward all angles diffusion, then destroy conditioned reflex and penetrate by light guide plate is positive.By various densitys, light guiding points not of uniform size, can make the light guide plate uniformly light-emitting.
Light guide plate can play the function of light diffusion, but independent light guide plate is preferential to the effect of light diffusion, also need to cooperate a light diffusing sheet to carry out, existing way is to repave the last layer light diffusing sheet at the face in light guide plate, because the transmittance of light diffusing sheet is good not, add between light diffusing sheet and the light guide plate gapped, so light intensity loss is larger.Assembly is too much simultaneously, and thickness also causes increasing to some extent, can't satisfy the miniaturization requirement, and production cost is also higher.
[utility model content]
The purpose of this utility model is exactly the problem that exists in order to solve prior art, has proposed a kind of light guide plate with diffusion layer, and other provides a kind of LED lighting with this light guide plate.
Concrete technical scheme of the present utility model is as follows:
The utility model provides a kind of light guide plate, and this light guide plate comprises a transparent panel, and the one side of described transparent panel is combined with a light diffusion layer.
The thickness of described light diffusion layer is 5 μ m～80 μ m.
The face relative with light diffusion layer of described transparent panel is stained with a plurality of light guiding points, and a plurality of light guiding points form light conductive dot array.
Described light diffusion layer contains the light diffusion particle.
The face at described light diffusion layer place is the exiting surface of light guide plate.
The non-exiting surface of described light guide plate also posts reflectance coating.
The utility model also provides a kind of LED lighting, and this LED lighting comprises lamp body and lampshade, comprises driving power, LED luminophor in the described lamp body, and described lampshade comprises a light guide plate, it is characterized in that, described light guide plate is aforesaid light guide plate.
The technique effect that the utility model is useful is:
By the one side seal light guiding points at transparent panel, another side seal optical diffusion film (being light diffusion layer) has been eliminated the gap between light diffusing sheet and the light guide plate like this, and light intensity loss is little, can improve the brightness of illumination.
On the other hand, when the LED lampshade was circular arc, the gap between light guide plate and the light diffusing sheet can be strengthened, and light intensity loss is larger, and adopts technology of the present invention, and directly the spray printing photodiffusion material forms after the light diffusion layer, and light intensity loss is little, and brightness is high.
