Description
Technical Field
The utility model relates to the technical field of light guide plates, in particular to a light guide plate of a breathing lamp of a mobile phone camera.
Background
With the rapid development of science and technology, a light guide plate is arranged on the periphery of the mobile phone camera for beauty, and a circle of light ring can be formed during use, but the original light usually irradiates the surface of the light guide plate, the residual light is scattered from the outer ring of the light guide plate, the brightness of the outer ring is weak, the beauty effect of the light guide plate is affected, and therefore improvement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a light guide plate of a breathing lamp of a camera of a mobile phone to solve the problems in the background technology.
In order to achieve the above purpose, the utility model provides the following technical scheme:
a light guide plate of a mobile phone camera breathing lamp comprises a light guide plate ring body; the bottom of the light guide plate ring body is provided with at least one light inlet; the lower surface of the light guide plate ring body is adhered with a lower reflecting film; an upper reflection film is adhered to the position, corresponding to the light inlet, of the upper surface of the light guide plate ring body; the periphery of the light guide plate ring body is provided with sawteeth.
For further description of the present invention, the light guide plate ring body is made of PC material.
For further description of the present invention, the light inlet is a slot; the groove body penetrates through the inner wall of the light guide plate ring body.
For further description of the present invention, the two light inlets are disposed at the bottom of the light guide plate ring body and distributed left and right.
The utility model is further described, the sawteeth are arranged in two groups and distributed in front and back on the periphery of the light guide plate ring body.
The utility model is further described, and the inner ring of the light guide plate ring body, the upper part corresponding to the light inlet and the position corresponding to the periphery of the light inlet are all provided with shading grains.
For further description of the present invention, the upper reflective film and the lower reflective film both use 0.05mm white single-sided adhesive.
The utility model has the beneficial effects that:
the LED lamp source is upwards arranged at the position of the light inlet, the light source irradiates the light inlet, meanwhile, the upper reflecting film reflects the residual light into the light guide plate ring body, the light path is changed, the light loss is reduced, the lower reflecting film also reflects the light into the light guide plate ring body, the utilization rate of the light is improved, and the light rays are gathered together through the peripheral sawteeth, so that the light guide brightness of the product is higher, and the uniformity is better.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 1-4, a light guide plate for a camera breathing lamp of a mobile phone comprises a light guide plate ring body 1; the bottom of the light guide plate ring body 1 is provided with at least one light inlet 11; the lower surface of the light guide plate ring body 1 is adhered with a lower reflecting film 2; an upper reflection film 3 is adhered to the position, corresponding to the light inlet 11, of the upper surface of the light guide plate ring body 1; the periphery of the light guide plate ring body 1 is provided with sawteeth 12; the LED lamp source sets up in going into light mouthful 11 position department up, and the light source is on going into light mouthful 11, goes up reflective film 3 and reflects the afterglow again to light guide plate circle body 1 simultaneously in, changes the route of light, reduces the light loss, and lower reflective film 2 also reflects light to light guide plate circle body 1 in, improves the utilization ratio of light, and light gathers together through periphery sawtooth 12 for the luminance of product leaded light is higher, and the homogeneity is better.
The light guide plate ring body 1 is made of a PC material, the light guide plate is made of an acrylic PC or PMMA material generally, and the light guide plate ring body is made of the PC material.
The light inlet 11 in the design is a groove body; the groove body is communicated with the inner wall of the light guide plate ring body 1, the LED lamp is located below the groove body, and light is emitted from the top of the groove body.
Go into light mouthful 11 and set up two and control the distribution in light guide plate circle body 1 bottom, the both sides light-emitting improves the degree of consistency of light, still can set up three or four according to actual demand.
The sawtooth 12 sets up two sets ofly and distributes the setting around light guide plate circle body 1, and the light source shines into the back from two income light ports 11 of left and right sides, shines to the front and back both sides position and passes through this sawtooth 12 spotlight and penetrate.
The upper reflecting film 3 and the lower reflecting film 2 both adopt 0.05mm white single-sided adhesive, and the emissivity is more than 83 percent.
The working principle of the embodiment is as follows:
the LED lamp source sets up in going into light mouthful 11 position department up, and the light source is on going into light mouthful 11, goes up reflective film 3 and reflects the afterglow again to light guide plate circle body 1 simultaneously in, changes the route of light, reduces the light loss, and lower reflective film 2 also reflects light to light guide plate circle body 1 in, improves the utilization ratio of light, and light gathers together through periphery sawtooth 12 for the luminance of product leaded light is higher, and the homogeneity is better.
The above description is not intended to limit the technical scope of the present invention, and any modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
