Description
Technical field
The utility model relates to a kind of LED light fixture, more particularly refers to a kind of directly welded LED Projecting Lamp.
Background technology
In prior art, at the LED light trade, its heat radiation is a technical barrier.So far, each large LED light fixture manufacturing firm does not all have better way to solve this heat dissipation problem.The radiator structure that existing employing aluminium base and thermal grease are bonding causes the heat radiation temperature difference between LED, aluminium base and aluminium base (casing of street lamp) larger, and the LED junction temperature is higher.More than 70 ℃ the time, LED lamp pearl will be subject to badly damaged, causes light decay, affects the life-span of whole LED light fixture when the LED junction temperature.
At present, adopt aluminium base (pcb board a kind of) to be applied on LED, its radiating effect is not good enough.Particularly need to arrange one deck heat radiation adhesive between aluminium base and aluminum alloy casing and be bonded together, thermal resistance is too large.After the LED heat conducted to aluminium base, the heat of aluminium base just can be directly transferred on the casing of street lamp body by thermal paste, caused LED and skin temperature higher.And the junction temperature of LED lamp pearl or LED module is during greater than 75 ℃, and the life-span of LED can shorten greatly.In addition, thermal grease can be aging through long-term the use, can not reach radiating effect and easily cause contact insufficient, and the inhomogeneous local temperature that also can make lamp of dispelling the heat is too high and affect the life-span.
Therefore, be necessary to develop a kind of more direct radiator structure, to solve the heat dissipation problem of LED light fixture.
