At present, the general led chip that is of a size of below the 10*26mil that adopts of single direct insertion LED on the market, about it used electric current as 20mA, voltage was between 3.0 ~ 3.4V; Power is 0.06 ~ 0.068W, and this direct insertion LED white-light emitting brightness is low excessively, and chip size is little; Not anti-high temperature is wasted time and energy in the time of will being assembled by many (thousands of up to a hundred of as many as) when its white light finished product is used simultaneously, and temperature is high; Heat radiation is not enough, causes the light decay of direct insertion LED big, and useful life is short.
Summary of the invention
The objective of the invention is to provide to the deficiency of prior art a kind of high temperature resistant, light decay is little, the direct insertion LED of the small-power of long service life.
The object of the invention is realized through following technical measures: the direct insertion LED of a kind of small-power; Comprise metallic support, led chip, electrode gold thread, fluorescent glue, insulation primer and epoxy encapsulation colloid, said led chip is positioned at the bowl-type groove at said metallic support top, and said led chip is connected through said electrode gold thread with said metallic support; Said fluorescent glue is covered in said led chip top; Said insulation primer is arranged at the bottom of said led chip, and said metallic support, said led chip and said electrode gold thread encapsulate through said epoxy encapsulation colloid, and said led chip is of a size of 20*20mil; Its normal point light current is 100 ~ 150mA; Lighting voltage is 3.0 ~ 3.4V, and it uses electric current is 20 ~ 40mA, and working voltage is 2.8 ~ 3.1V.
Preferable, in technique scheme, said metallic support is the large scale support that is complementary with said led chip.
Preferable, in technique scheme, said fluorescent glue is for being carrier with silica gel and the colloid of fluorescent material mixing gained.
Beneficial effect of the present invention is: led chip of the present invention is set to large size chip, and it is of a size of 20*20mil, and the white light heat conduction and heat radiation is effective, can be high temperature resistant; Its normal point light current is 100 ~ 150mA simultaneously, and lighting voltage is 3.0 ~ 3.4V, and it uses electric current is 20 ~ 40mA; Working voltage is 2.8 ~ 3.1V, and during work, the actual use electric current of the logical 40mA of going up that only needs is lighted the present invention; Can replace two common undersized direct insertion LED that light with the 20mA electric current, therefore, when utilization the present invention carries out the assembling of white light finished product; Can reduce temperature, thereby make light decay of the present invention little, the life-span is long.
