Abstract

The invention relates to an LED (light emitting diode) high-power illuminating lamp holder which comprises a lamp holder body, wherein the front end of the lamp holder used as a heat radiator is provided with a mounting hole used for mounting an LED high-power illuminating lamp; the periphery of the lamp holder body is provided with a multi-blade type heat radiating fin; the lamp holder body is internally provided with a heat radiating cavity, and the peripheral part of the heat radiating cavity is permeable; and the heat radiating fin is provided with a wind drawing hole. The lamp holder not only can be used as a lamp holder, but also can be used as a heat radiating device of the LED illuminating lamp and ensures that the temperature of an LED chip is controlled to be below normal working temperature, and the temperature at the end of the chip is lower than that of a heat radiating top end, thereby improving the service life of the whole LED illuminating lamp.

Description

LED high-power illumination lamp lamp socket
Technical field
The present invention relates to a kind of lamp socket, refer in particular to a kind of LED high-power illumination lamp lamp socket.
Background technology
LED is a kind of solid semiconductor device, and it can directly be converted into visible light to electric energy, because its excellent specific property and environmental protection are attached great importance to its application at lighting field once people occurring.But, desire to make LED really to substitute existing illuminating lamp, must solve two hang-ups: (1) improves small cup light flux; (2) solve heat dissipation problem.In order to improve a light flux (lumen), will increase led chip power.Because the restriction of semiconductor light-emitting-diode wafer technologies at present, the photoelectric transformation efficiency of LED is still waiting to improve, especially great power LED, higher because of its power, nearly electric energy more than 60% will become heat energy and discharge (along with development of semiconductor, photoelectric transformation efficiency can improve gradually), in utilizing high power LED product, must carry out heat radiation, guarantee that the high-power LED chip operating temperature is controlled at below 80 ℃, so that the product operate as normal.Existing LED high-power illumination lamp adopts radiator to dispel the heat usually, and there is obvious defects in radiator usually: (1) heat radiation power is little, can only be used for the LED illuminating lamp below 10 watts; (2) radiating effect is bad, and the LED illuminating lamp chip operation temperature more than 10 watts is all more than 80 ℃, have in addition above 100 ℃; (3) the used heat dissipation metal material proportion of every watt of lamp power (consumable quantity/watt) is big.
Summary of the invention
The objective of the invention is to the defective that prior art exists, a kind of LED high-power illumination lamp lamp socket is provided, it both used as lamp socket, can be used as the heat abstractor of LED illuminating lamp again, the temperature of led chip is controlled at below the normal working temperature, and accomplish that the die terminals temperature is lower than the heat radiation top, improved the whole lamp life-span of LED.
For achieving the above object, the solution that the present invention adopts is: a kind of LED high-power illumination lamp lamp socket, it comprises the lamp socket body, be provided for installing the installation hole of LED high-power illumination lamp as the lamp socket body front end of radiator, leafy formula fin is set around the lamp socket body, the heat radiation chamber is set in the lamp socket body, and part is penetrating around the heat radiation chamber, offers on the fin and draws the wind hole.
When lamp is worked, the heating of LED high-power illumination lamp, the installation hole that LED high-power illumination lamp is installed begins heat absorption, and heat conducts in the lamp socket body, fin begin to around heat radiation (during situation in the chamber of not dispelling the heat, fin is only to the heat radiation of outside air), the heat radiation chamber has been arranged, and part is penetrating around the heat radiation chamber, thermolysis is not only played but also rise and take out heat effect in the heat radiation chamber, the hot gas pulling of rising of being dispelled the heat in the chamber of fin inner face is also dispelled the heat, and hot gas rises, and to take out heat effect very effective; Add to have offered on the fin and draw the wind hole, further encouraged the heat effect of taking out in heat radiation chamber.Like this, accomplished that lamp socket body front end temperature (die terminals temperature) is lower than tail end (heat radiation top) temperature, the temperature of led chip is controlled at below the normal working temperature, improved the whole lamp life-span of LED.
Description of drawings
Fig. 1 is that the present embodiment master looks fragmentary cross-sectional view.
Fig. 2 is the present embodiment vertical view.
Fig. 3 is the present embodiment upward view.
Among the figure: 1, lamp socket body, 2, installation hole, 3, the heat radiation chamber, 4, fin, 5, draw the wind hole.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.
Referring to Fig. 1-Fig. 3, a kind of LED high-power illumination lamp lamp socket, it comprises lamp socket body 1, be provided for installing the installation hole 2 of LED high-power illumination lamp as lamp socket body 1 front end of radiator, leafy formula fin 4 is set around the lamp socket body 1, heat radiation chamber 3 is set in the lamp socket body 1, and part is penetrating around the heat radiation chamber 3, offers on the fin 4 and draws wind hole 5.
Referring to Fig. 1 and Fig. 3, be drum shape in the middle of the described heat radiation chamber 3, outwards mill out four lumen cavity recess around the drum again equably.This heat radiation chamber 3 design is ingenious, dispels the heat with to take out thermal effect very good.
Referring to Fig. 1-Fig. 3, described wind hole 5 straight-through lamp socket body 1 and the fin 4 that draw draw the 5 minutes four component cloth in wind hole, and every group is four and draws wind hole 5.Draw wind effective, further improved lamp socket body 1, more effectively encourage the heat effect of taking out in heat radiation chamber 3 as the effect of radiator and the thermolysis of fin 4.
Referring to Fig. 1-Fig. 3, according to the watt level of lamp, the profile size and the physical dimension of design lamp socket body 1.Be example now, do one relatively with common radiator with 50 watts of LED high-power illumination lamps.50 watts of netted encapsulated LED are contained in the common radiator, and bright lamp is after one hour, 30 ℃ of environment temperatures, and it is as follows to measure Temperature Distribution: led chip end maximum temperature is 93 ℃, radiator tail end temperature is 80 ℃; 50 watts of netted encapsulated LED are contained in the installation hole 2 of lamp socket body 1 (appearance and size of lamp socket body 1 is roughly the same with common radiator), bright lamp is after one hour, 30 ℃ of environment temperatures, it is as follows to measure Temperature Distribution: led chip end maximum temperature is 50 ℃, lamp socket body 1 tail end is 61 ℃, the temperature difference opposite with common radiator occurred.Be not difficult to find out that the radiating effect of the invention can satisfy 20 watts, 30 watts, 50 watts to 100 watts fully, even the more requirement of high-powered LED lamp.
