The needle shaped heat dissipation design of LED explosion-proof lamps increases the surface area for heat dissipation. There are gaps between the needle shaped columns, which can quickly generate convection and achieve multi-directional heat dissipation, thus achieving the goal of rapid cooling.
Technical advantages:
The ideal light source is LED, which is a solid-state cold light source with a long service life. It operates at a safe low voltage and has low power consumption and heat generation. Its electro-optical conversion efficiency is also low, resulting in low energy consumption. Therefore, LED explosion-proof lamps using LED as a light source are an ideal light source. 2. The explosion-proof technology used in LED explosion-proof lamps is circuit sealing technology, and its explosion-proof technology can meet the requirements and regulations of the country. It is an electrical equipment used in special industries, mainly used to solve lighting problems. 3. Low heat dissipation LED explosion-proof lamps have a very low heat generation, making them a very safe explosion-proof lighting fixture that can be used for lighting in various industries. How to choose LED explosion-proof lights:
Overview
The intrinsic performance of LED explosion-proof lights is mainly reflected in the configuration of electrical appliances, but often people overlook the heat dissipation problem of LED lights, especially the heat dissipation of LED explosion-proof lights.
performance analysis
The shell temperature of LED explosion-proof lamps itself is a performance assessment of explosion-proof lamps, because the environment in which explosion-proof lamps are installed contains flammable gases, and the heated surface of the shell itself is a source of danger. If the shell is too high, it will lower the temperature range of the entire lamp and reduce its usage range. So when LED explosion-proof lamp manufacturers design lamps, they will increase the heat dissipation area and increase the weight of the heat sink, which is why LED explosion-proof lamps are heavier than ordinary LED lamps.
Market Analysis
The LED explosion-proof lamp market is currently quite chaotic, and LED explosion-proof lamps can be basically divided into three categories. According to national standards, the explosion-proof structure and temperature group meet the requirements, and the nameplate labeling is also truthful; The second type of explosion-proof structure meets national standards, but in order to reduce costs and save materials, the wall thickness is reduced, resulting in a lower temperature rating. However, if customers need it, it will still be sold according to the higher temperature rating; The third category is products that do not meet the requirements for explosion-proof structure and temperature group, and are considered unqualified.
selection method
Speaking of which, everyone should know that there are two key factors when choosing LED explosion-proof lights: explosion-proof structure and temperature group. But this is still difficult for many users. Because explosion-proof structures are a relatively professional matter, you may be confused by several explanations from salespeople; The temperature group is also the same. The shell has a large heat dissipation, which is definitely beneficial for the light source, but it is unknown how high the temperature of the shell is appropriate. A simple way to tell everyone here is to measure the weight of the heat sink for LED explosion-proof lights of the same power. The relatively heavy one is generally good. Manufacturers of low-quality LED explosion-proof lights are not willing to spend costs on radiators. This is a very simple and effective method. Do you know how to choose LED explosion-proof lights.
