Latest company news about How to choose the heat sink of the LED flood light-Shenzhen Riyueguanghua Technology Co., Limited

LED flood light is an indispensable part of LED outdoor lighting. It can fully adapt to the normal use of indoor and outdoor humidity environment with IP65 waterproof grade. It is especially suitable for landscape buildings, outdoor squares, landscapes and walls. The surface and display color are very suitable for outdoor lighting, such as buildings, courtyards, museums, exhibits, stadiums, squares and piers. It is also suitable for pavilions, flowers, trees, parks, passages, bridges, etc. lighting project. Shenzhen Riyueguanghua Technology Co., Limited

 

The heat dissipation of portable flood light singapore has always been the biggest headache for manufacturers. The quality of heat sinks is the primary problem that directly affects the size of light decay. The three basic methods of heat dissipation technology and heat transfer are: conduction, convection and Radiation and thermal management are also started from these three aspects, which are divided into transient analysis and steady state analysis. The main transmission route of the radiator is conduction and convection heat dissipation, and the radiation heat dissipation under natural convection cannot be ignored. Most of the lighting fixtures use high-power LEDs . At present, the luminous efficiency of commercial high-power LEDs is only 15% to 30%, and most of the rest of the energy is converted into heat. If heat is not effectively discharged, it will have serious consequences. High temperature will reduce the luminous flux of LED and its luminous efficiency, cause red shift of light wave, color cast, and cause aging of devices. The most important thing is to reduce the life of LEDs exponentially, due to the light decay of LED or its lifetime. Shenzhen Riyueguanghua Technology Co., Limited. It is directly related to its junction temperature. The heat dissipation is not good, the junction temperature is high, and the life is short. According to the Arrhenius rule, the temperature will be extended by 2 times for every 10 °C decrease in temperature.

However, the appearance of the rechargeable flood light on the market now almost violates the principle of LED heat dissipation. It is modified in violation of the heart, and the molds are not only insufficient, but also the aluminum alloy is not enough, and the heat sink is cut corners and shoddy! The thickness of the original radiator and the heat dissipating teeth are thinned and shortened. After the same wattage test, the surface temperature of the modified thin casing has reached 85° or more, which is 60° than the original normal surface temperature. On the basis of 65 ° degrees, it will rise directly by more than 30%. How can such a lamp housing guarantee the service life of the lamp? And if you can improve the quality of LED lights! Shenzhen Riyueguanghua Technology Co., Limited
It is recommended that all LED manufacturers should join hands to resist unqualified and inferior products, and also a benign development of the LED market! For your company's healthy development, a common appeal: use genuine, high-qualityphilips led flood lights price list housing! Use a good shell to get the lights done!
