Abstract
The utility model proposes a kind of LED lamp, comprise PN junction, the first electric conductor, the second electric conductor, external conductor and substrate, described PN junction is directly installed on the first electric conductor and the second electric conductor and is electrically connected with described the first electric conductor and the second electric conductor respectively, described the first electric conductor and the second electric conductor are directly installed on external conductor, and described external conductor is installed on substrate.The utility model is simple in structure, and good heat conduction effect has reduced PN junction internal temperature, has improved luminous efficiency and the useful life of PN junction.
Description
Technical field
The utility model relates to a kind of light-emitting device, is specifically related to a kind of LED lamp.
Background technology
At present, the general employing of LED lamp is connected by insulating barrier PN junction with fin, and the heat of PN junction is gone out by insulating barrier and fin conductive, because the pyroconductivity of insulator is very low, so luminous efficiency and the useful life of the serious restriction of its heating meeting PN junction.As the LED lamp of the prior art of Fig. 1, PN junction is connected with fin by insulation spacer, has reduced like this heat transfer efficiency of fin, and the heat in PN junction can not effectively outwards be conducted.Therefore,, for fear of the shortcoming existing in prior art, be necessary prior art to make improvements.
Utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of simple in structure, LED lamp that heat conduction efficiency is high is provided.
The utility model is to realize by following technical scheme: a kind of LED lamp, comprise PN junction, the first electric conductor, the second electric conductor, external conductor and substrate, described PN junction is directly installed on the first electric conductor and the second electric conductor and is electrically connected with described the first electric conductor and the second electric conductor respectively, described the first electric conductor and the second electric conductor are directly installed on external conductor, and described external conductor is installed on substrate.Described the first electric conductor and the second electric conductor are electrically connected with PN junction as pin conductor, and first and second electric conductor directly conducts heat to external conductor, by external conductor, heat are conducted, thereby have improved electrical efficiency, reduce PN junction internal temperature.
The opposite end of described the first electric conductor and the second electric conductor has the depression platform of installing for PN junction.Be conducive to sealing and the heat radiation of PN junction.
Described depression platform be shaped as duck's foot shape.
With respect to prior art, the utility model is by being directly located at PN junction on first and second electric conductor, heat in PN junction is directly conducted heat by first and second electric conductor, do not need by insulating trip, heat to be conducted to fin, improve heat conduction efficiency, thereby improved luminous efficiency and the useful life of LED lamp.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The LED lamp of prior art as shown in Figure 1, comprises PN junction 1, pin 2, external conductor 3, fin 4, insulation spacer 5 and substrate 6.
Of the present utility model a kind of LED lamp as shown in Figure 2, comprise PN junction 1, the first electric conductor 7, the second electric conductor 8, external conductor 3 and substrate 6, this PN junction 1 is directly installed on the first electric conductor 7 and the second electric conductor 8 and is electrically connected with the first electric conductor 7 and the second electric conductor 8 respectively, this first electric conductor 7 and the second electric conductor 8 are directly installed on external conductor 3, and this external conductor 3 is installed on substrate 6.The first electric conductor 7 and the second electric conductor 8 are electrically connected with PN junction 1 as pin conductor, first and second electric conductor 7,8 directly conducts heat to external conductor 3, by external conductor 3, heat is conducted, thereby improved electrical efficiency, reduce PN junction 1 internal temperature.External conductor 3 is copper-clad plate.
The opposite end of the first electric conductor 7 and the second electric conductor 8 has the depression platform of installing for PN junction 1, is conducive to sealing and the heat radiation of PN junction 1.This depression platform be shaped as duck's foot shape.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
