Abstract
A light-emitting diode (LED) lamp with high heat dissipation performance comprises a lamp socket, a radiator, LED light source blocks and a lampshade. Each LED light source block comprises an LED lamp wick and a cone-shaped heat conduction wick, and the LED lamp wick is embedded on the upper portion of the heat conduction wick. The radiator comprises a hollow cone-shaped heat dissipation frame and cooling fins, wherein the lower portions of the cone-shaped LED light source blocks are embedded into the cone-shaped heat dissipation frame, the cooling fins are evenly and vertically distributed on the periphery of the cone-shaped heat dissipation frame, the cooling fins are of a hollow structure, and the cooling fins are provided with through holes. According to the LED lamp with the high heat dissipation performance, the hollow cooling fins with the holes are used, the heat radiating area of the cooling fins is enlarged, the hollow structures of the cooling fins can form heat flow which is overflowed from heat radiating holes, and heat dissipation efficiency is effectively improved. Therefore, the luminous efficiency and the reliability of the LED light source blocks are improved, and the service life of the LED lamp is prolonged.
Description
Technical field
The utility model relates to a kind of light fixture, is specifically related to a kind of LED light fixture of high heat dispersion.
Background technology
LED has begun scale in the application of lighting field, and one of bottleneck that restricts the high-capacity LED development at present is a heat dissipation problem.Along with the raising of LED power, the substrate scattering property is required to improve greatly, if the heat of the LED that can not dissipate effectively is directly connected to the illumination effect and the life-span of light fixture.The heat of LED lamp concentrates in the size chip seldom, can make that the chip internal temperature is more and more higher, not only quickens light fixture and wears out, and reduction of service life, can cause chip to burn when serious.At the heat radiation difficult problem of LED lamp, the radiator of LED lamp is multifarious on the market, but very complicated is compared in design mostly, has influenced the efficient of producing in batches.
The utility model content
In order to solve above-mentioned technological deficiency, it is a kind of simple in structure that the utility model provides, the LED light fixture of high cooling efficiency, long service life.
The technical scheme that the utility model adopted is: a kind of LED light fixture of high heat dispersion, comprise lamp socket, radiator, led light source piece and lampshade, described led light source piece comprises the heat conduction core of LED wick and taper, the LED wick is embedded in the top of heat conduction core, described radiator comprises the taper heat radiation rack and the fin of hollow, the bottom of conical led light source piece embeds in the taper heat radiation rack, periphery at the taper heat radiation rack evenly vertically is distributed with fin, described fin is a hollow structure, is furnished with through hole on the fin.
The through hole of described every fin evenly distributes.
Beneficial effect: the utility model adopts hollow and fin with holes, has not only increased the area of dissipation of fin, and heat distributes by fin, and the hollow structure of fin forms hot-fluid and overflow from louvre, effectively improves radiating efficiency; Thereby improve led light source piece luminous efficiency and reliability, and prolonged the service life of LED light fixture.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: 1, lamp socket, 2, fin, 3, the taper heat radiation rack, 4, the led light source piece, 5, lampshade.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further specified.As shown in Figure 1, a kind of LED light fixture of high heat dispersion, comprise lamp socket 1, radiator, led light source piece 4 and lampshade 5, described led light source piece 4 comprises the heat conduction core of LED wick and taper, the LED wick is embedded in the top of heat conduction core, described radiator comprises the taper heat radiation rack 3 and the fin 2 of hollow, the bottom of conical led light source piece 4 embeds in the taper heat radiation rack 3, periphery at taper heat radiation rack 3 evenly vertically is distributed with fin 2, described fin 2 is a hollow structure, is furnished with through hole on the fin.The through hole of described every fin 2 evenly distributes.The utility model adopts hollow and fin with holes, and when increasing big area of dissipation, hollow structure that can fin forms hot-fluid and overflows from louvre, effectively improves radiating efficiency; Thereby improve led light source piece luminous efficiency and reliability, and prolonged the service life of LED light fixture.
