Where is the key to LED explosion-proof lights?
The quality of the LED explosion-proof lamp depends on what, led explosion-proof lamp cooling performance directly affects the quality of the product, LED explosion-proof lamp cooling performance how to choose to choose it.
The quality of LED explosion-proof lamps takes the initiative. Most of this depends on its thermal performance. The heat dissipation of LED explosion-proof lamps depends not only on its heat dissipation mode, but also on its heat-dissipating materials. The heat-dissipating material definitely has its service life. Heat dissipation is a major factor affecting the lighting intensity of LED lighting fixtures. LED lighting tools are 80 percent more energy efficient than traditional incandescent lamps, but their LED components and driver circuits dissipate a lot of heat. If these heats are not discharged properly, the luminosity and lifespan of lighting fixtures will drop sharply.
And its heat-dissipating material is especially important. There are generally three kinds of heat-dissipating materials: pure aluminum radiators, pure copper radiators, and copper-aluminum combined radiators. Now LED explosion-proof lights basically use the national standard 102 # die-casting aluminum, easy molding, heat dissipation is also good, in the case can not change the shell material, it can only be assembled from the accessories to optimize, to improve, one is aluminum, Be sure to use a plate with a thermal conductivity of 2.0 or more. This material is calculated as a square, about 450-500 yuan per square. Below this price, you must consider that thermal conductivity is not enough. The second is the selection of thermal pastes. Many people believe that this is only a minor issue. This problem is very important. It is also one of the important factors that determine whether heat can be emitted during the use of LED explosion-proof lamps. The thermal conductivity of aluminum substrates is no better. The thermal conductivity of the thermal paste does not work, the heat can not be transmitted, and the third is the fixed aluminum substrate screws, many people think that as long as playing a few screws is enough, if so think, that behind the 100% will regret it, the more fixed screws More, the larger the contact surface between the aluminum substrate and the aluminum shell is, the better the fit is, and the heat dissipation is not better. Let's think about it. There is also a problem, many manufacturers of circular LED explosion-proof lights have been processed through the lathe, the car across the plane, but why square, we just use the grinder to gently grind it? Personally think that the processing conditions in the factory are not enough, and the second is that the processing costs are relatively high, in order to save the cost of this piece. Whatever the reason, for the sake of product quality, please do not reduce the process.
The most important thing is the selection of LED lamp beads. Nowadays, many people are using imitation lamp beads. Everyone can go to the lamp beads specification. It can be found that when the lamp beads are in the working process, the temperature of the lamp beads is lower than the center point of the lamp beads. The outside temperature will be 15 degrees higher. If there is a temperature of 55 degrees above the housing, then the temperature at the center of the lamp beads will be 70 degrees. If you use the lamp beads of the Kerui 3535, check the specifications and find out the lamp during work. The temperature of the center point of the bead is only 5 degrees higher than the outside world. Then the same shell, the same accessories, different lamp beads, and the temperature of the LED lamp bead center point chip will be about 10 degrees lower. In addition, the Kerui 3535's lamp bead uses a ceramic base. His heat dissipation performance is better. Knowledgeable people all know why people are not willing to use it because the cost is too high.
Each factory has engineers, dealers there are also technical personnel, or can access the Internet, we can consult, the same LED explosion-proof lights, can make LED lamp beads temperature is low 10 degrees, which means that the LED explosion-proof lights The service life can be much longer.
Said for a long time, is to tell everyone that low-cost LED explosion-proof lights, can not buy high-quality LED explosion-proof lights, Rongrong ROLAN do the most cost-effective LED explosion-proof lights, we guarantee that our price is not the cheapest, but We guarantee that, with the same quality, the price is absolutely the lowest, and we only cooperate with knowing the technology and pursuing high-quality care.
