LED, as the fourth generation lighting, with characteristics of energy conversation, environmental, longevity, compact, is now widely used in various fields such as lighting.  displaying,piloting, decoration, backlight and so on.

LED products
At present , LED electro-optic conversion efficiency is only about 20-30%,about other 70% energy is turned into heat.That is why there is urgent desire in LED heat dissipation. 
Heat dissipation structure of LED street lamp thermal silicone pad
Electrons combining holes can only engender approximate 90% photons. Current leakage reduces the recombination efficiency in PN region, the leakage current multiplied by the voltage is the power of this part,which is converted into heat. 

Not like 15lm/w incandescent lamp converting almost all electric into light and eliminating the heat dissipation problem,only 30% of the internal photons of LED can be emitted to the chip and others finally converted into heat.
Heat dissipation structure of thermal pad for LED downlight
LED chip will generate extremely excessive heat in limited space, surmount its heat capacity, this requires efficient heat conduction avoid junction temperature occurrence.    
Application of thermal silicone grease heat dissipation structure in LED street lamp

Continuous high temperature of LED lamp caused by working chip, will impact on its service life and stability seriously.the lower the luminous rate brings the higher temperature.


This confusing attracts more and more attention Shenzhen Opute Electronic technology Co.,LTD has successively developed allround-performance ,user-friendly targeted products for LED market.
silicone thermal pad and LED radiator working diagram
Opute thermal grease series: fine paste, high thermal conductivity.
The heat dissipation structure of LED lamp is made of thermal conductive silicone grease, which has good thermal conductivity and insulation

In order to satisfying mutiple scenarios users, Opute silicone thermal pad series have various structure, besides taking glass fiber and silicon fabric as reinforcement carrier, designing both single and double sided adhesive to fasten PCB and radiator.

                                                                         

Opute thermal double-sided tape, 1.0W/m.k-1.5W/m.k ,superior retention. Widely used in cementing PCB/FPC and radiator.
In the application of low volatile thermal conductive putty in LED, it has high heat conductivity and good insulation performance, which greatly improves the service life and performance of LED products
Opute thermal putty series,  good thermal conductivity and weather resistance, fit to complicated structure products, in addition to denoise of dimming products.
Opute silicone glue series are organic silicone adhesive products with lots of outstanding characteristics: solidify at room temperature, excellent resisting to low and high temperature alternating, no corrosion to metals, aging resistance, anti-seismic,damp proof, good electric insulating and leakage property.
                                                                             
Therefore, in addition to improving the design, it is necessary to select appropriate thermal interface materials in LED.
