Description

Light emitting diode

Technical field

This utility model relates to a kind of diode, particularly relates to a kind of light emitting diode.

Background technology

At present, the light emitting diode on market is a lot, divides, including LED from principle of luminosity Light emitting diode, LE chemiluminescence diode, divide from mounting means, including direct insertion and patch Flat type LED, these diodes can reach preferable effect from illumination effect, but Being in production and processing and to install and use and there is more defect, crudy is poor, yield rate is low.

Therefore, it should provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

The purpose of this utility model is: provide a kind of light emitting diode.

For achieving the above object, the technical solution adopted in the utility model is:

Light emitting diode, including weld tabs and crystal grain, the both sides of crystal grain are provided with weld tabs, the two of weld tabs End is fixedly installed copper sheet, and copper sheet connects pin, and weld tabs and pin outer surface are coated with resin bed, The two sides of resin bed are arc surface, are provided with luminescent wafer in arc surface, and resin bed is coated with Reflecting piece, reflecting piece is externally provided with heat dissipating layer.

Pin includes copper outer layer and steel inner core.

Reflecting piece undulate.

In technique scheme, compared with prior art, the advantage possessed is: at resin bed Installing luminescent wafer on interior arc surface, erection space is big, it is simple to install；Reflecting piece presents ripple Shape wave, can spread the light-emitting area of light source；The heat energy that diode can be produced by heat dissipating layer is timely Disperse, extend the service life of diode.

Accompanying drawing explanation

Accompanying drawing 1 is this utility model embodiment one structural representation.

In the figures above: 1-weld tabs, 2-crystal grain, 3-copper sheet, 4-pin, outside 41-is copper Layer, 42-steel inner core, 5-resin bed, 6-arc surface, 7-luminescent wafer, 8-reflecting piece, 9-heat dissipating layer.

Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.

Embodiment one:

As it is shown in figure 1, light emitting diode of the present utility model, including weld tabs 1 and crystal grain 2, brilliant The both sides of grain 2 are provided with weld tabs 1, and the two ends of weld tabs 1 are fixedly installed copper sheet 3, and copper sheet 3 connects and draws Foot 4, weld tabs 1 and pin 4 outer surface be coated with resin bed 5, and the two sides of resin bed 5 are circular arc Face 6, is provided with luminescent wafer 7 in arc surface 6, resin bed 5 is coated with reflecting piece 8, reflecting piece 8 Being externally provided with heat dissipating layer 9, pin 4 includes copper outer layer 41 and steel inner core 42, reflecting piece 8 in Waveform.Installing luminescent wafer 7 on arc surface 6 in resin bed 5, erection space is big, just In installation；Reflecting piece 8 presents waveform, can spread the light-emitting area of light source；Heat dissipating layer 9 The heat energy that diode produces can be dispersed in time, extend the service life of diode.

Above-described embodiment is only for illustrating technology of the present utility model design and feature, and its purpose exists In allowing person skilled in the art will appreciate that content of the present utility model and to implement according to this, and Protection domain of the present utility model can not be limited with this.All according to this utility model spirit institute The equivalence change made or modification, all should contain within protection domain of the present utility model.
