Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of radiator structure of LED lamp.
Background technology
The LED lamp is one of the novel green light source of conventional incandescent bulb as an alternative, has good market prospects.About the LED lamp with material and processing technology, the process used of light fixture industry has following several at present: (1) general plastics: use plastic injection-moulded technique, but the radiating effect extreme difference of material of general plastics own; (2) heat-conducting plastic: use plastic injection-moulded technique, the radiating effect of heat-conducting plastic is slightly better than general plastic material, and still, on market, variation is not yet carried out in the product development of heat-conducting plastic, and therefore, this material still belongs to expensive material; (3) aluminium alloy: use extrusion process, the aluminium alloy material must could be accepted by market through procedure after multiple.Because processing technology is loaded down with trivial details, indirectly increase cost, so production unit cost is higher; The aluminum alloy material that is fit to die casting only has a few aluminium material available on market; Although the radiating effect of aluminium alloy is better than heat-conducting plastic, need do in appearance because of it spray paint coating or electroplating processes, its radiating effect is had a greatly reduced quality; (4) aluminium section bar: use aluminium extruded type or aluminium to take out technique, the material of aluminium section bar must be after secondary procedure, and use milling process just can be processed into the required modeling effect in market, so the production unit cost of aluminium section bar is high, manufacturing cost is increased.The aluminium section bar radiating effect is better than aluminium alloy compression casting material.
According to the above description as can be known, the material that cheap, processing procedure is conveniently taken again soon, as plastics, heat-conducting plastic, be only suitable for using for the light fixture of low wattage power.Therefore, consider heat radiation and performance, all use the good metal material of thermal conductivity (as aluminium alloy and aluminium section bar) to make heat abstractor at present, but because the heat loss through radiation area of heat abstractor is limited, cause radiating effect still not good, thereby affected the life-span of LED lamp.
The utility model content
The utility model provides a kind of LED lamp that dispels the heat good, improves by the radiation aluminium body to the LED lamp, to solve the deficiency of prior art.
In order to solve the problems of the technologies described above, the radiator structure of LED lamp of the present utility model, be located in the LED lamp, this LED lamp comprises Lamp cup and is installed on lamp holder and the diffuser at Lamp cup two ends, and described Lamp cup inside is provided with circuit board, and the bottom of described Lamp cup is the design of closing up, its inside also is provided with support, described support extends and accommodates described circuit board along the Lamp cup inwall, also is provided with radiation aluminium body and aluminium base in the accommodation space that described Lamp cup and diffuser form, and aluminium base is provided with LED lamp pearl.Wherein, described radiation aluminium body comprises a matrix, and this matrix periphery evenly is provided with some radiating fins, forms heat dissipation channel between described some radiating fins.Also be provided with perforate on described Lamp cup.
Further, the radical length of described some radiating fins is identical.
Further, the radical length of described some radiating fins is less than the diameter of the matrix of this radiation aluminium body.
Further, described some radiating fins are aluminium alloy radiating fin or aluminium section bar radiating fin.The matrix of described radiation aluminium body is aluminium alloy radiation aluminium body or aluminium section bar radiation aluminium body.
Further, described radiation aluminium body is provided with through hole and some screw holes for locking, because of aluminium alloy and the aluminium section bar price higher, therefore offer through hole, not only can increase area of dissipation, can also save material cost.
LED bulb lamp of the present utility model has the radiation aluminium body of heat radiation fin structure by employing, greatly increased surface area, and form heat dissipation channel between some radiating fins, the perforate that arranges on this heat dissipation channel and Lamp cup forms convection current, form a good heat dissipation channel, greatly strengthened radiating effect.
Description of drawings
Fig. 1 is the explosive view of LED lamp in embodiment of the present utility model.
Fig. 2 is the stereogram of the radiation aluminium body in embodiment of the present utility model.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As a specific embodiment, the utility model is take the LED bulb lamp as example.As depicted in figs. 1 and 2, the radiator structure of this LED lamp is applied in the LED lamp, and this LED lamp comprises Lamp cup 2 and is installed on lamp holder 1 and the diffuser 6 at Lamp cup 2 two ends, Lamp cup 2 inside are provided with circuit board 3, and circuit board 3 comprises by dull and stereotyped power panel and the lamp plate that connects of accumulation of heat; The bottom of Lamp cup 2 is the design of closing up, and its inside also is provided with support 21, and support 21 extends and accommodates circuit board 3 along Lamp cup 2 inwalls.The end of lamp holder 1 also has electrode 8.
Also be provided with radiation aluminium body 4 and aluminium base 5 in the accommodation space that Lamp cup 2 and diffuser 6 form, aluminium base 5 is provided with LED lamp pearl, being shaped as of the matrix 41 of radiation aluminium body 4 is cylindrical, and its matrix 41 peripheries evenly are provided with some radiating fins 42, form heat dissipation channel between some radiating fins 42.These some radiating fins 42 realize increasing area of dissipation by increasing surface area.Radiation aluminium body 4 and aluminium base 5 are by screw 7 lockings.
Concrete, the radical length of these some radiating fins 42 is identical, and its radical length is less than the diameter of the matrix 41 of this radiation aluminium body 4.These some radiating fins 42 are preferably selected the material same with matrix 41, can aluminium alloy or aluminium section bar.
