Problems solved by technology

The higher the power of the LED, the greater the heat generated, and the heat generated by a single high-power LED and an integrated high-power LED is very concentrated, especially for embedded LED lamps, the heat sink is not exposed to the circulating air, and its heat dissipation It is more difficult, and the heat sinks commonly used at present are strip-shaped parallel arrangements, and its heat dissipation capacity is obviously insufficient, especially not suitable for cylindrical embedded LED lamps

Embodiment Construction

[0016] Such as figure 1 , figure 2 and image 3 As shown, the present invention includes a heat sink 1, a power supply 2 and LEDs fixed on the base 3, the heat sink 1 is arranged on the base 3 in a ring shape, and the heat sink 1 and the base 3 constitute a heat sink, this arrangement The spatial shape of the radiator can be fully utilized, combined with the principles of heat conduction and heat convection, so that the radiator can meet the requirements of optimized shape structure, excellent heat dissipation effect and light weight to the greatest extent.

[0017] The shape of the base 3 is cylindrical, conical, ellipsoidal or other shapes. What is shown in the figure of the present invention is an ellipsoidal base 3. circular arrangement.

[0018] The heat sink 1 and the base 3 are preferably of an integral structure. The bottom ring 9 is used to connect the radiator and the reflector 10, and also has an aesthetic effect. The fixing piece 11 or the elastic piece is us...

Abstract

The embedded LED lamp has heat sink arrangement favorable to heat dissipation. It includes heat sinks arranged in alary ring on one base, power source, and LED's fixed on the base. It has optimized heat dissipating effect, optimized shape and light weight. At the same time, the present invention has scattering lens comprising convex lens set and Fresnel lens to reduce glare, raie illuminance and reduce dispersion. The proper installation mode of the present invention makes the embedded LED lamp possess light homogeneity and even heat dissipating condition.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an embedded LED lamp. Background technique [0002] With the development of semiconductor lighting technology, LED has gradually developed from traditional low power to single high power and integrated high power, but LED can only work normally when the temperature is not higher than a certain temperature. The higher the power of the LED, the greater the heat generated, and the heat generated by a single high-power LED and an integrated high-power LED is very concentrated, especially for embedded LED lamps, the heat sink is not exposed to the circulating air, and its heat dissipation It is even more difficult, and the heat sinks commonly used at present are strip-shaped parallel arrangements, and its heat dissipation capacity is obviously insufficient, especially not suitable for cylindrical embedded LED lamps. Contents of the invention [0003] The technical problem to be solved by the present ...
