Foshan Liangyin Aluminum Co., Ltd

Custom aluminum heatsink for LED with CNC machining in Foshan Factory Product Description The main function is to continuously export the heat generated by the LED chip to the environment, so that the temperature of the chip remains within the required range, so as to ensure that the LED lamp can operate normally.The quality of the radiator mainly depends on the thermal resistance of the radiator, the smaller the thermal resistance, the lower the LED lamp temperature under the same conditions, the lower the LED temperature, the longer the service life of the chip will be.The heat resistance of the radiator shall include heat conductivity heat resistance and heat dissipation heat resistance.

Brief Introduction of Extruded Aluminum Heatsink in LED Lamp Compared with traditional lights, LED (Light Emitting Diode) lamps have the advantages of long service life, energy saving, and high light efficiency. In recent years, LED lights are increasingly used in various industries, such as street lamps, industrial and mining lamps, landscape lamps, indoor lighting, etc. However, the LED lamp also has certain disadvantages. For example, its calorific value is very high, and when the temperature rises to a certain degree, it will affect the lifespan and luminous effect. In practice, LED light conversion efficiency is about 30%. The remaining 70% will be released as heat. LED heat rise has a direct impact on luminous efficiency, main wavelength instability, low chromatic aberration. Therefore, for a good LED lights, the first to consider is the heat dissipation problem, the choice or design of a good heat sink is crucial.

    1. Light weight: Aluminum is about 1/3 the weight of sand-cast or die-cast aluminum, making aluminum extrusions easier to handle. 2. Reflective: The surface can be polished or brushed to produce reflective or matching components, making aluminum extrusions attractive. 3. Flexibility: Aluminum combines strength and flexibility to bend under load or spring back from impact, leading to the use of extruded components in automotive crash management systems. 4. Corrosion resistance: Aluminum extrusions have excellent corrosion resistance. They do not rust and the aluminum surface is protected by its own natural oxides. A protection that can be enhanced by a powder coating. 5. Strong: Aluminum profiles can be made as strong as needed for most applications, and due to the nature of the extrusion process, strength can be concentrated where it is really needed by including different wall thicknesses and internal reinforcement in the profile design. Extrusions are particularly well suited for
