Description

The radiator structure of LED light fixture

Technical field

The utility model refers to a kind of radiator structure of the LED of being used for light fixture especially relevant for a kind of radiator structure.

Background technology

Because light emitting diode (LED) has good brightness, long life-span, advantage such as power saving more, has been widely used on the indoor or outdoor lighting device by manufacturer at present; Yet, influence the most remarkable factor of LED length in service life, for being provided, these LED can under working environment, operate than thermophilic; Therefore, the design people is promptly so that the radiator structure of LED light fixture to be provided, as research topic of the present utility model.

The radiator structure of known LED light fixture, TWM307091 discloses as the novel letters patent book number of TaiWan, China, this radiator structure comprises radiating seat, it has " M " shape substrate, above substrate, be formed with several dissipation fins, the below of substrate then connects for plural LED installing, and is combined into the LED light fixture.

Yet, the radiator structure of known LED light fixture, on using, reality still has following problem, this substrate is under the consideration of various situations such as cost, service condition, assembling easness, load, its volume is subjected to the limitation of certain degree, and can't have no restrictedly outwards to increase, and adds it and only on the plane of substrate radiating fin is set, formed overall cooling surface area is quite rare, and can not satisfy the radiating requirements of various high-capacity LEDs; Really remain to be improved.

The utility model content

In view of this, the purpose of this utility model is to provide the radiator structure of the better LED light fixture of a kind of radiating effect.

In order to reach above-mentioned purpose, the utility model provides a kind of radiator structure of LED light fixture, in order to provide the LED installing to connect, comprise radiating seat, it has substrate, on upper and lower two planes of this substrate, be respectively equipped with plurality of radiating fins, and respectively be formed with the accommodation space that installs for LED between this radiating fin on the plane of this substrate.

By such scheme as can be known, the radiator structure of LED light fixture of the present utility model after the LED of LED lamp socket group is activated, can conducts to the heat that each LED produced on substrate and each radiating fin by the temperature-uniforming plate on the radiating seat and dispels the heat.Because the utility model all is provided with radiating fin on the upper and lower plane of substrate, can be under the restricted situation of volume, its cooling surface area still can significantly increase, each LED is lowered the temperature rapidly, thereby make it in working environment, operate than thermophilic, and the service life that can significantly improve each LED.

The specific embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

Please refer to shown in Figure 1, be stereogram of the present utility model, the utility model provides a kind of radiator structure of LED light fixture, it mainly comprises radiating seat 1, radiating seat 1 rectangular body, definition has relative two short side and relative two long sides, substrate 11 with aluminium material, the one aluminium extruded forms plurality of radiating fins 12 respectively on upper and lower two planes of substrate 11, each radiating fin 12 is equidistantly to arrange, and on the two sides of each radiating fin 12, be formed with protruding sour jujube 121 respectively, to increase area of dissipation; Between the plurality of radiating fins 12 of substrate 11, be formed with circular accommodation space 13 in addition in the bottom surface; And, be formed with plural buckle groove 14 at two outside radiating fins, 12 outer surfaces.

Please refer to shown in Figure 2, for the utility model and temperature-uniforming plate and lamp socket component are separated sectional view, radiator structure of the present utility model also comprises temperature-uniforming plate 2, and can make up mutually to constitute LED light fixture 10 with LED lamp socket group 3, this temperature-uniforming plate 2 is installed in the accommodation space 13 of radiating seat 1, and the one plane is sticked on substrate 1, another side then is sticked mutually with LED lamp socket group 3, this temperature-uniforming plate 2 has vacuum-packed housing 21, and be provided with capillary structure and working fluid (figure does not show) in housing 21 inside, transmit heat by the heat biography mechanism that vapour, liquid phase change.And this LED lamp socket group 3 includes disc lamp socket 31, to be installed in the accommodation space 13, in lamp socket 31, be provided with circuit board 32, circuit board 32 one sides are attached on the temperature-uniforming plate 2, circuit board 32 another sides then are equipped with a plurality of LED 33, in addition at lamp socket 31 away from the lateral surface place of radiating seat 1 lens 34 that have been sticked, the light that LED 33 is produced sees through these lens 34 and exhales.

Please refer to Fig. 3 and shown in Figure 4, be compound section figure and the stereogram of the utility model Fig. 2, be provided with locking hole 111 on the substrate 11 of radiating seat 1 corresponding to accommodation space 13, then cross-under has locking post 311 in lamp socket 31; During assembling, even temperature-uniforming plate 2 is attached in the accommodation space 13 and fits with substrate 11, the circuit board 32 that a plurality of LED 33 will be installed again is fixed in the lamp socket 31, pass in the locking hole 111 that lamp socket 31 is locked in substrate 11 at last, and LED lamp socket group 3 and temperature-uniforming plate 2 are combined with radiating seat 1 by locking post 311.
