Abstract
The utility model relates to an adjustable radiator structure for a LED (light-emitting diode) lamp. The adjustable radiator structure comprises a lower pressing plate, an upper pressing plate, a heat pipe and a radiating fin. A lamp bead is bonded with an aluminum base plate that is tightly bonded with the lower pressing plate, and the lower parts of the heat pipes are tightly bonded with the upper pressing plate and the lower pressing plate through screws. A hole and a radiating hole allowing the corresponding heat pipes to penetrate are arranged at the bonded position between the upper pressing plate and lower pressing plate, and the middle part of the radiating fin is provided with a hole and a radiating hole allowing the corresponding heat pipes to penetrate. The number of the heat pipe penetrating through the radiating fin, the upper pressing plate and the lower pressing plate is at least one. Compared with the traditional radiator structure, the adjustable radiator structure has the advantages of good radiating effect, low cost and large variability, can realize regulation according to the radiation loss, meets different radiation demands of different powers and types of lamps, and is significant in reducing the product cost and prolonging the service life.
Description
Technical field
The utility model belongs to field of light fittings, relates to a kind of lamp radiator structure, relates in particular to a kind of LED light fixture and uses adjustable heat spreader structures.
Background technology
At present; At lighting field, the application of LED luminous product is just attracting common people's sight, and LED is as a kind of novel green light source product; Must be world's lighting field developing tendency in future, it be the novel illumination light source epoch of representative that 21st century will get into LED.The main cause of LED product heating is that the electric energy that is added does not all change into luminous energy, and its electric light transformation efficiency approximately has only about 20% ~ 30%, that is to say, about 70% ~ 80% electric energy has changed into heat.So the heat radiation of LED product more and more receives people's attention.This is that the bad junction temperature of dispelling the heat is just high because the light decay of LED product or life-span are relevant with junction temperature, and the life-span is just short.According to the A Leiniusi rule, 10 degrees centigrade of the every reductions of temperature, the life-span can prolong 2 times.It is thus clear that can well solve heat dissipation problem, fundamental influence arranged to improving the LED life of product.The LED street lamp of general heat dissipation technology is non-adjustable because of its radiator, often cause product can not seriation, variation.Its result just forms radiator of a product, makes cost high, and versatility is poor.Therefore, design a kind of adjustable changeable LED lamp radiator structure, for realizing that product diversity, interchangeability, versatility have very important meaning.
The utility model content
The purpose of the utility model is to provide a kind of Adjustable structure, uses the LED light fixture simple, that cost is lower, heat dispersion is good to use adjustable heat spreader structures.
The technical scheme of the utility model is: a kind of LED light fixture is used adjustable heat spreader structures, comprising: lower platen, top board, heat pipe, fin; Lamp pearl and aluminium base fit together, aluminium base and the fastening applying of lower platen simultaneously, and the heat pipe bottom fits tightly through screw and top board, lower platen.
Top board, lower platen are provided with the hole that can pass corresponding heat pipe between fitting, and a louvre at least also will be set.
The fin middle part is provided with the hole that can pass corresponding heat pipe, and a louvre at least also will be set.
Heat pipe through fin and top board, lower platen at least one.
Accessible beneficial effect was after the utility model adopted technique scheme: compare with traditional heat-dissipating device structure, the utility model mechanism is simple, and radiating effect is good; Cost is low; Changeability is big, can realize according to the size of heat dissipation capacity regulating, and satisfies the different heat dissipation capacity demands of different capacity model light fixture; For reducing product cost, there is important meaning in the raising life-span.
Description of drawings
Fig. 1 looks sketch map for a kind of LED light fixture of the utility model with adjustable heat spreader structures master.
Fig. 2 looks sketch map for a kind of LED light fixture of the utility model with an adjustable heat spreader structures left side.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.Like Fig. 1 ~ shown in Figure 2, in the present embodiment, a kind of LED light fixture is used adjustable heat spreader structures, comprising: lower platen 3, top board 4, heat pipe 6, fin 7; According to what (sizes of heat dissipation capacity) of lamp pearl 1 quantity, the quantity of length that can free adjustment heat pipe 6 and quantity, fin 7.Heat pipe 6 bottoms fit tightly through screw 5 and top board 4, lower platen 3, and top board 4, lower platen 3 are provided with some hole and louvres that pass corresponding heat pipe 6 between fitting.Fin 7 middle parts are provided with the hole and the louvre that can pass corresponding heat pipe 6.Heat pipe 6 through fin 7 and top board 4, lower platen 3 is installed.
The lamp pearl 1 heat sink heat that distributes passes to lower platen 3 through aluminium base 2; Heat pipe 6 is realized and the fitting tightly of top board 4, lower platen 3 through screw 5; To realize that heat is delivered to heat pipe 6, through the exchange heat of fin 7 realizations, to reach the heat radiation purpose with environment.Top board 4, lower platen 3 materials are aluminium alloy, and heat pipe 6 materials are copper pipe, and fin 7 materials adopt copper sheet.
Compare with traditional heat-dissipating device structure, this use new structure is simple, good heat dissipation effect; Cost is low, and changeability is big, can realize according to the size of heat dissipation capacity regulating; Satisfy the different heat dissipation capacity demands of different capacity model light fixture, for reducing product cost, there is important meaning in the raising life-span.
