Technical field

The utility model relates to the lighting apparatus field, refers to a kind of powerful, energy-conservation LED lighting that can be in work under the low-temperature condition especially.

Background technology

At present, because the environmental protection of LED light fixture, energy-conservation and be extensive use of by masses.Known LED has powerful characteristics more, but increase with its power, the also corresponding increase of the evolution of heat, and the LED substrate mostly is aluminum substrate because the thermal conductivity of metal, during light fixture work because the light fixture poor radiation, the heat that sends is absorbed by substrate, substrate temperature raises, and makes the service behaviour of led section descend, and has shortened the light fixture working life greatly.

Though the technical staff smears coolant such as silicone grease or adopts high heat conducting coating to improve the heat conduction and the radiating efficiency of LED substrate and radiator by the joint portion in the LED substrate in radiator, prolong light fixture service life; But the thickness of coating is limited, can only derive the part heat, so the light fixture that is suitable for is limited in scope; Because the development of society, more and more higher to the requirement of light fixture, for the bigger light fixture of power, when the evolution of heat was excessive, the heat conduction and heat radiation effect of coating just can be had a greatly reduced quality, and did not guarantee the normal service life of large-power lamp.

Summary of the invention

For addressing the above problem, the utility model provides a kind of heat conduction and heat radiation efficient height, can guarantee that light fixture in low-temperature condition work down, is applicable to the high-power LED energy-saving lighting lamp.

For achieving the above object, the technical solution adopted in the utility model is: on power supply, radiator, the LED substrate, transmissive mirror and protecgulum are linked in sequence, be equipped with installed part in both sides, protecgulum flange below, wherein, power supply by have on its lid male member be connected radiator between form the troposphere, there is inner chamber at described radiator center, be provided with ventilation slot around it, be equipped with the chamber lid, base station is arranged in the relative end of accent in the inner chamber accent, described LED substrate is connected on the base station, described transmissive mirror places LED substrate top to be plugged on the base station with its protruding key, and described protecgulum is socketed on the base station of radiator above transmissive mirror.

The heat sink of the inner chamber outside of described radiator is radial, and it is nonmetal to be marked with high heat conduction in this inner chamber, and its chamber is placed on accent with connector sealing locking.

The base station of described radiator is the thermal-arrest plate, and this base station is with the more than one positioning hole of its top, fits tightly with screw with the LED substrate to be connected.

There is the material feeding groove described protecgulum inside, and it is nonmetal to be marked with high heat conduction in the material feeding groove.

Described high heat conduction is nonmetal to be nontoxic, and environment-friendly materials, its thermal conductivity factor are 10 times of thermal conductivity factor of aluminium at least.

Described power supply is the pressure-stabilizing constant flow driving power, and the electric capacity in its power supply is solid capacitor.

The flexible part that is connected and fixed on the described installed part.

The beneficial effects of the utility model are: the material feeding groove design of the inner chamber of radiator and protecgulum, nonmetal in conjunction with the high heat conduction of injecting, nontoxic, environment-friendly materials, the heat that sends when making light fixture work is better absorbed by material feeding, by the radiator release heat, guarantee that effectively the light fixture led section is in work under the low-temperature condition better, has guaranteed the normal service life of light fixture; Adopt the driving power of high efficiency pressure-stabilizing constant flow, make the service life of power supply and the service life of LED lamp be complementary, adopted solid capacitor, to prolong the service life of driving power.
