Description
Technical field
The utility model relates to technical field of electronic devices, specifically relates to a kind of electronic device indicator lamp translucent construction.
Background technology
Present electronic product function is more and more, and also more and more to the requirement of function, corresponding inner electronic device is just more and more, therefore, causes inner goods of furniture for display rather than for use space also more and more not enough.Cause the not corresponding situation of corresponding construction on internal electronic device and the shell thus.Such as indicator lamp (LED lamp) because of the influence in space can not with the indicator lamp zone on the shell on the throne put corresponding, both certain distances that may stagger, during the light transmission indicator lamp zone that can cause indicator lamp so partially secretly and luminance nonuniformity.
The utility model content
The purpose of the utility model is to address the above problem, and a kind of electronic device indicator lamp translucent construction is provided, and a kind of electronic device indicator lamp of the utility model translucent construction has overcome the above-mentioned luminous dark partially and uneven problem of printing opacity.
A kind of electronic device indicator lamp of the utility model translucent construction; Comprise LED light and transparent area; It is characterized in that; Also comprise LGP, said LGP is between LED light and transparent area, and said LGP comprises the light entrance face that is used to import light into LGP, derive light from LGP light-emitting face, angle of inclination are more than or equal to first mirrored sides of the angle of total reflection of light when LGP penetrates and angle of inclination second mirrored sides more than or equal to the angle of total reflection of light when LGP penetrates; The contiguous LED light of said light entrance face, the contiguous transparent area of said light-emitting face.
The plane of incidence of said LGP, first mirrored sides, second mirrored sides are burnishing surfaces, help the total reflection of light like this, can be owing to the coarse destruction total reflection of reflecting surface.
The light-emitting face of said LGP is a cloudy surface, helps the diffuse scattering of light like this.
The light entrance face of said LGP is a burnishing surface, can prevent that like this incident light from plane of incidence generation scattering, making most of light all get into LGP.
The light entrance face of said LGP and the fore-and-aft distance between the LED light are 0.3mm to 0.6 mm, can guarantee that so most light gets into LGP.
The area of the light-emitting face of said LGP is more than or equal to the area of transparent area, and the light ratio of sending from transparent area like this is more even.
A kind of electronic device indicator lamp of the utility model translucent construction increases LGP between LED light and transparent area, utilize the total reflection of LGP side will be from the photoconduction of LED light incident to transparent area; Like this, though LED light and transparent area dislocation, also can be with photoconduction to transparent area; Solved that the transparent area printing opacity does not work and the problem of non-uniform light, and said indicator lamp translucent construction is fairly simple; Do not have the requirement of distinctive appearance, moulding and assembling are than being easier to.

The specific embodiment
The specific embodiment of a kind of electronic device indicator lamp of the utility model translucent construction is provided below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model electronic device indicator lamp translucent construction.In this embodiment, LED light is as mobile phone indicator lamp (charging, bluetooth, promptings such as incoming call/information).Please refer to shown in Figure 1, LED light 1, transparent area 2, the LGP 3 between said LED light 1 and transparent area 2; Wherein, LGP 3 comprises the light entrance face 4 that is used to import light into LGP, is that first mirrored sides 6 and the angle of inclination of 45 degree is second mirrored sides 7 of 45 degree from light-emitting face 5, angle of inclination that LGP is derived with light; Said light entrance face 4 contiguous LED lights 1, said light-emitting face 5 contiguous transparent areas 2.
In this embodiment, LGP 3 is to adopt the perspex material to process, such as the PC material of leaded light level; Generally, the refractive index of perspex material is about 1.42, therefore; When light penetrated from this material, the angle of total reflection was approximately 42 degree, is ± 1.5 degree and manufacture error; So the angle of reflecting surface is more preferably greater than 42 degree, total reflection just can take place in light therein like this; Therefore, in this embodiment, first mirrored sides 6 of LGP 3 and the angle of inclination of second mirrored sides 7 are set to 45 degree.Like this, total reflection can take place in first mirrored sides 6 and second mirrored sides 7 in light, makes light not penetrate from the side.
In this embodiment, the light entrance face 4 of LGP 3 is that burnishing surface can prevent that like this incident light from plane of incidence generation scattering, making most of light all get into LGP; First mirrored sides 6 and second mirrored sides 7 also are burnishing surface, help the total reflection of light like this, can not destroy the total reflection of light owing to reflecting surface is coarse; Light-emitting face 5 is cloudy surfaces, and this coarse surface helps the light outgoing, and can make light scattering even.
The light that LED light 1 is sent gets into LGP 3 through light entrance face 4; Total reflection takes place in wherein a part of incident light on first mirrored sides 6; The light of total reflection is the second mirrored sides generation total reflection more again; From light-emitting face 5 outgoing, total reflection takes place in another part incident light on second reflecting surface 7 then, and the light of total reflection is from light-emitting face 5 outgoing; Fig. 2 is the LGP light path sketch map of the utility model first embodiment, and light path please refer to shown in Figure 2 in the LGP; Send from transparent area 2 from the light of light-emitting face 5 outgoing, pilot light is provided.
Fig. 3 is the structure cutaway view after the assembling of a kind of electronic device indicator lamp of the utility model translucent construction.Please refer to shown in Figure 3ly, appearance part 8 (like LENS, TP etc.) is assembled on the fore shell 10 through double faced adhesive tape 9; Wherein transparent area 2 is positioned on the appearance part 8, and LED LGP 3 is assembled into fore shell 10, and the pcb board 11 that has LED light 1 also is assembled on the fore shell 10; LED light 1 and LGP 3 light entrance faces help the incident of light so longitudinally apart from 0.3mm to 0.6mm, reduce the loss as far as possible; LED light 1 is not less than 0.4mm with the distance of other structures on every side; Give LED light 1 certain space like this, make assembling carry out more easily, simultaneously also can be through each item test.The area of the light-emitting face 5 of LGP 3 otherwise less than the area of transparent area 2 can guarantee that like this brightness of transparent area outgoing is strong and evenly.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
