Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of heat sinking block mounting structure, be use a kind of with photoconduction with the use of heat sinking block mounting structure.
The technical solution of the utility model is achieved in the following ways: a kind of heat sinking block mounting structure, by photoconduction, aluminum-based circuit board, LED, conduction estersil, radiating block, radiating block position limiting structure, radiating block base plate, radiating block gear piece, radiating block leg and Decorative Cover form, photoconduction be arranged on Decorative Cover, on; Aluminum-based circuit board is positioned over the front of radiating block by radiating block position limiting structure, and radiating block position limiting structure is placed on radiating block leg, and conduction estersil in aluminum-based circuit board backside is also arranged on the front of radiating block; It is characterized in that: described radiating block is fixed in Decorative Cover, the centre of luminescence heating of LED4
,conduction estersil conducts heat
,radiating block dispels the heat.
The centre of luminescence of described LED is just to the light inlet of photoconduction.
Described radiating block is arranged in Decorative Cover by radiating block leg.
The utility model, structure is simple, can effectively prevent great power LED because using the excessive low light efficiency caused of electric current, the LED junction temperature caused because LED heat is too high is too high, luminous intensity is low, light decay is serious and electronic devices and components are impaired, prevent light leak and non-uniform light phenomenon, improve the environment resistance to vibration of radiating block simultaneously.

Detailed description of the invention
Known by Fig. 1, a kind of heat sinking block mounting structure, by photoconduction 1, aluminum-based circuit board 3, LED4, conduction estersil 5, radiating block 6, radiating block position limiting structure 7, radiating block base plate 8, radiating block gear piece 9, radiating block leg 10 and Decorative Cover 11 form, and photoconduction 1 is arranged in Decorative Cover 11; Aluminum-based circuit board 3 is positioned over the front of radiating block 6 by radiating block position limiting structure 7, and radiating block position limiting structure 7 is placed on radiating block leg 10, and conduction estersil 5 in aluminum-based circuit board 3 backside is also arranged on the front of radiating block 6; Described radiating block 6 is fixed in Decorative Cover 11, the centre of luminescence heating of LED4
,conduction estersil 5 conducts heat
,radiating block 6 dispels the heat.
Being known by Fig. 2, is the main schematic diagram of guide structure.The centre of luminescence of described LED4 is just to the light inlet 2 of photoconduction 1.Photoconduction 1 of the present utility model adopts optical grade PC, and light guide adopts total reflection tooth to design, and light inlet designs for spherical structure, ensures not light leak and uniformly light-emitting by the appropriate design of light inlet.
Being known by Fig. 3, is the main schematic diagram of aluminum-based circuit board.Aluminum-based circuit board 2 is made up of great power LED, wiring board base plate.The evenly luminous effect of photoconduction, the layout of its LED4 has two kinds of modes usually: a kind of is that the LED4 centre of luminescence is just to the light inlet 2 of photoconduction 1; Another kind LED4 is arranged in immediately below photoconduction profile of tooth.What the present embodiment was mainly taked is mode in first, and namely the LED4 centre of luminescence is just to the light inlet of photoconduction, requires that photoconduction distance LED has certain distance, avoids because rigging error factor causes LED light lenslet to come off.
Being known by Fig. 4, is the structural representation of radiating block.Described radiating block 6 is arranged in Decorative Cover 11 by radiating block leg 10.Connect aluminum-based circuit board 2 and photoconduction 1, guarantee that LED light center is aimed at photoconduction light inlet 2, radiating block 6 need design radiating block position limiting structure 7.Consider that output and the temperature of luminous intensity are inversely proportional to, think and need the luminous intensity requirement that guarantee is certain constantly to dispel the heat to great power LED.LED4 is in ignition, its chip can constantly generate heat, these heats will be delivered in aluminum-based circuit board 2, but these heats transmitted also rest on light fixture LED unit position, for the heat of light fixture LED unit position is shed, need at aluminum-based circuit board 2 rear design cooling mechanism, guarantee heat by carrying out in LED chip-aluminum-based circuit board-conduction estersil-radiating block-air ambient transmitting, all gentle heat radiation.For ensureing the environment resistance to vibration that radiating block is certain, radiating block 6 need design radiating block leg 10 and be installed in Decorative Cover 11.
Being known by Fig. 5, is radiating block position limiting structure schematic diagram.Radiating block 6 of the present utility model is the good conductor of the heat with a lot of radiating block gear piece 9.When designing radiating block structure, in order to obtain better radiating effect, first, radiating block base plate 8 will have certain thickness, in order to resist the impact of transient thermal load.Secondly, under the prerequisite meeting aluminium casting die casting, radiating block gear piece 9 thickness and spacing should be reduced as far as possible, increase radiating block gear piece 9 quantity and height, ensure certain free convection, improve radiating effect.In whole radiator structure, the major function of radiating block base plate 8 is that the heat produced by aluminum-based circuit board 2 light source is derived, and the major function of radiating block gear piece 9 is dissipated by heat.The Main Function of radiating block position limiting structure 7 is the location correcting the LED4 centre of luminescence and photoconduction light inlet 2, thus ensures the uniformly light-emitting of its photoconduction 1.The Main Function of radiating block leg 10 plays installation fixation, in order to improve the environment resistance to vibration of radiating block 6.Therefore, suitable radiating block base plate 8 thickness, radiating block gear piece 9 height, radiating block position limiting structure 7 and radiating block leg 10 is designed particularly important.
