Heat dissipation solution for LED lamps3

LED offers exciting design opportunities, and all the talk about it is often hampered by the words: heat management. “When incandescent bulbs can consume heat through radiation, LED produce almost no infrared heat.” “Said Michael Gershowitz, director of technology marketing for pry. Therefore, LED must heat through heat conduction, or there is a risk that the brightness,

Manufacturers are now more pursuing simple and easy-to-use products. Since it is a simple and easy project, the over-complexity of the kit will be difficult to achieve. As we all know, heat to transfer has three major ways – conduction, convection, radiation. Let’s talk about the possible room for improvement in the design and application

LED cooling design

Thursday, 22 March 2018 by

From a thermal design point of view, a typical LED lamp includes an LED light source, a printed circuit board (PCB), and a cooling system. The LED light source includes a semiconductor chip (light emitting portion), an optical element, a package, and a heatsink for taking the heat of the chip. The heatsink is soldered on the

Aluminum alloys are widely used in LED heatsink because of their light weight, good appearance, good thermal conductivity and easy processing into complex shapes. There are mainly three types of aluminum alloy heatsinks: flat-width, comb-shaped, or fish-bone-shaped, and round or oval-shaped outer radiating fins are radial pattern. Their common characteristics are: the short distance between the fins,

How do you choose LED heatsink?

Monday, 19 March 2018 by

We often find heatsinks in electrical appliances or computers. It is a device that dissipates heat easily to heatable components in appliances or computers. Most of them are made of aluminum alloy, brass, or bronze. Such as. If the heat emitted by the components is conducted to LED heatsink, it will be distributed to the

The performance of LED heatsink can be represented by the cooler thermal resistance Rhs. The formula is as follows: Rhs=(Tmax-TA)/P Tmax: LED heatsink maximum temperature (°C); TA: Ambient temperature (°C); P: Heat dissipation of LED heatsink (W) LED heatsink temperature is defined as shown in the figure below In forced convection cooling system equipment, when

Aluminum is the best material for heat dissipation, but aluminum products are expensive and have a low frequency of use, and the process itself is greatly limited. Therefore, the style is little, and the long-term use of aluminum have limited the speed of development and renewal. The plastic is an insulator, and its heat dissipation performance

LED downlights have gained greater room for growth in the domestic market. They have entered super markets, home improvement markets and engineering fields. They have gained recognition of consumers for more prominent lighting effects and higher product quality. Downlight can be said to be the most popular quality. Earlier due to the expensive LED lamp beads, the overall cost of LED downlight

With the widely use of LED lamps, how to increase their usage rate, reduce the warranty rate, and extend the use efficiency has become hot topics for a while. LED lamps are widely used in major shopping malls, office buildings, streets and other places, but they still cause higher costs due to heat dissipation problem. In order to
