Modern LED lights have been used in more and more lighting fields, and high-power LEDs have emerged as the times require. However, with the gradual increase of LED power, the problem of heat dissipation has become extremely prominent. When selecting an LED heat sink, the data of the heatsink specification will be used as a basis for judgment. In addition to the product series, type, diameter, height, net weight and other information in the specification, the key parameters of Thermal Resistance, Thermal Wattage, and Cooling Performance are of great significance to the heat dissipation performance analysis of the LED heatsink.Thermal Resistance（ºC/W）Thermal resistance usually refers to the resistance of the heat flow through the object.That is, the quotient obtained by dividing the difference between the effective temperature of the device and the externally specified reference point temperature by the steady state power dissipation in the device. Excessive thermal resistance makes the temperature too high, which directly affects the wavelength, luminous efficiency and service life of high-power LEDs. At present, the thermal resistance of power LEDs with good heat dissipation should be ≤10 ℃ / W, while the maximum thermal resistance of EtraLED heatsink series is only 7.69 ºC / W, and the minimum is even to 0.77 ºC / W. So this level can ensure the life of the power LED.Thermal Wattage（W）When current flows through the junction of the LED chip, the LED will produce visible light. However, LED efficiency is less than 100%, and a large amount of power flowing through the LED is output in the form of heat. Under normal operating conditions, approximately 50% to 60% of the input power is output as heat, and the remaining input power is converted into light. For the most conservative case, it is assume that LEDs convert 25% of the input power into light and output 75% of the input power in the form of heat. The thermal wattage data represents the amount of heat that can be absorbed. Cooling Performance（Im）Cooling Performance refers to the luminous flux in LED Academy. The luminous flux emitted by a light source in a unit time, among which the luminous flux that can be produced by the visual person (a person can feel it). Some people doubt whether LED luminous flux is large or small? Of course, it depends on the use of LED. Generally speaking, the larger the better. But the larger the luminous flux is, the more light sources are needed, and the larger the radiator is, the more expensive the price is. So the best choice is the right one. EtraLED heatsink series has a luminous flux range of 300 ~ 9700 Im. Customers can choose the most suitable specific model according to the situation of the LED.                Click on the following URL  to see why EtraLED heatsink is so suitable for you!   https://www.mingfatech.com/etraled-heat-sink   To sum up, when browsing the Mingfa Tech product brochure, each product must actually consider all aspects of its information. On the official website, there will be product specifications related to it, which are provided to customers as a deep understanding of the product data.

No matter how many watts, LED lights must dissipate heat. When the LED is working, about 80% of the electrical energy is converted into thermal energy, and 20% of the electrical energy is converted into light energy, and the LED heat sink is used to cool the LED. Then how to find a suitable heatsink, from the size of the LED light, the power of the LED light, and the use of the application scene in three major aspects of analysis. Selecting a suitable heat sink under certain heat dissipation conditions can ensure that the device or module works safely and reliably.LED light sizeThe size of a light affects the size of the installation, that is how large the diameter of the heat sink is. The lights come in different sizes, as do the heat sinks. In order to match the different installation sizes of each LED light, EtraLED heat sink has developed several standard sizes with diameters of Φ48, Φ70, Φ85, Φ96, Φ110, Φ130 for different schemes and customers to choose. At the same time, the chip of different brands determines the number and location of holes that need to be punched. In order to match the many COB brands, the EtraLED heat sink has also been optimized in the shape design to enable drilling and tapping according to customer requirements.LED light powerIn Mingfa Tech's product catalog, you will see the description of "TW (max) ", which actually means the dissipated power (maximum). Even if it is the same series with different diameters and heights, the dissipated power inside It will be different. In short, the power of the LED light needs to be lower than this dissipated power value. For example, if you have a 25-watt LED light on your hand, we chose the EtraLED series 70-diameter heat sink. But we found that if the height is 50, and the maximum cooling power is 22.9 W. What can we do? 1. Of course, you can choose other series of heatsinks that meet this requirement. 2. Customers are especially fond of the EtraLED series. You can slightly increase the height of the LED heat sink to solve this problem.Application ScenesWhen the LED chip is working, its own ambient temperature is inversely related to the light output rate. The higher the temperature, the lower the light output rate. When the temperature reaches the maximum temperature of the LED chip, the LED will be broken. At the same time, different lighting scenes, the required lights and matching heatsinks will change accordingly. For example, in the shopping malls in daily life, where downlights and spotlights are frequently used, the Etraled cooler will be a good choice, because both of them are suitable for customers to purchase in a unified large quantity and promote the completion of customers' lighting projects.Of course, if you want to solve this problem more professionally, you can choose to give it to Mingfa Tech's professional team to help you handle it.

Maybe most people know heatsinks are an important part of LED lighting. But it is not necessarily known that there is a heat sink that can match more than 20 COB brands in the market, accounting for 85% -95% of the module. Now from the three sides of its material, shape, and surface treatment, explain to why the compatibility is so strong, which is deeply loved by mass customers. Heat Sink MaterialThe thermal conductivity of the heat sink material is an important factor that directly affects the efficiency of heat dissipation through conduction, making the heat sink extremely strict in material selection. AL6063-T5, an aluminum alloy material, is an alloy formulated with aluminum, magnesium and silicon as the main element, and each element has a certain range of content. Unlike copper, which is costly and difficult to process, 6063 aluminum alloy is a universal and typical extruded alloy with excellent processability, excellent weldability, extruding and plating properties, good corrosion resistance and toughness. Easy to polish, color film and excellent anodizing effect. It is also the most widely used material for most heat sinks provided by MingfaTech, and EtraLED Heat sink uses this material.Heat Sink ShapeAs we all know, heat transfer occurs on the surface of the heat sink, so better heat sinks have larger surface area. Of course, this can be achieved by directly increasing the size of the heatsink, or by designing the heat sink. EtraLED Heat sink belongs to sunflower aluminum extruded LED cooler. Compared with the ordinary Sunflower series on the market, this heat sink optimizes and improves the blades to help more surface transfer heat. It has designed a proper spacing to give enough space. In order to allow the air to circulate better, to achieve a better state of heat dissipation.Heat Sink FinishThe treatment of the heat sink surface will also directly affect the thermal conductivity, and the surface of the EtraLED Heat sink will be anodized. What is the difference between LED cooler oxidation and non-oxidation? First, under the corresponding electrolyte and specific process conditions, an oxide film will be generated, which will improve the surface hardness and abrasion resistance of the aluminum alloy, thereby extending the service life of the aluminum profile heat sink. Second, the painted surface is actually better than the bright unpainted surface, which increases the aesthetics of the product and makes the metal feel stronger.Therefore, only when the heat dissipation capability of the heat sink is sufficiently good can the LED light be sufficiently durable. Etraeled heat sink can match COB of first-line light source brands in LED industry, such as Adura, Bridgelux, BJB, citizen, Cree, Edison, GE, LG, Lumileds, Lumens, Luminus, LEDIL, Nichia, OSRAM, Philips, Prolight Opto, Samsung, Seoul, sharp, Tridonic, Vossloh Schwabe, Xitao, zhaga, etc. This strong compatibility makes most LED lights choose EtraLED Heat sink. To learn more about the product, please click the following website https://www.mingfatech.com/etraled-heat-sink
