The four technical standards of LED explosion-proof lamps

1. Light source: LED chips with high brightness, high luminous efficiency and low light decay must be used. This requires the selection of LED lamp beads packaged with regular channel chips from brand chip manufacturers such as American Corey/Germany Osram, and packaged gold wires/phosphors. / Insulation glue, etc. need to use materials that meet the requirements. Tengxuan Explosion-Proof specializes in the production of industrial lighting fixtures. The products cover lamps used in professional fields and various types of explosion-proof lighting fixtures used in explosion-proof areas. The use of LED explosion-proof lamps all use the internationally renowned brand Osram LED. The quality assurance rate is quite high. Aluminum The substrate is equipped with the domestic advanced plastic film composite 2.0 coefficient high thermal conductivity aluminum substrate. It plays an important role in the service life of the LED.

2. Driving power supply: LED is a semiconductor component that converts DC electrons into light energy, so a stable drive requires a high-performance power supply driver chip, and the power factor pu compensation function is required to ensure power supply efficiency. The most important factor is that the quality of the LED power supply on the market is uneven, and the quality of the LED power supply is mixed. A good driving power supply not only ensures a stable DC supply, but also fully ensures the improvement of the conversion efficiency. This parameter reflects the lighting The real energy-saving and no waste to the grid. The LED lamps used by Ocean King explosion-proof are all designed with high-efficiency power supply solutions, with multiple protection functions, and the target value of output effective power is set at not less than 95%. The output power of LED floodlights has reached a conversion rate of 98%, which is called the industry leading level.

3. A heat dissipation system with a compact appearance structure, in addition to a high-end and elegant appearance, high-quality light source and power supply, an excellent lamp is more important is the structural rationality of the shell, which involves the heat dissipation of LED lamps, because LEDs convert light energy. At the same time, a part of the electric energy is also converted into heat energy, and the heat needs to be extracted and dissipated into the air, so as to ensure the stable lighting of the LED. It is worth mentioning that the technology of LED chips is constantly improving, and the conversion efficiency is also improved. The power consumption of heat conversion will be less, and the heat sink components will be thinner, which will also reduce costs due to some, which is conducive to the promotion of LEDs, but This is just a technical development direction. At present, the heat dissipation of the casing is still a parameter that must be investigated. The BC9700 high-power LED explosion-proof lamp completely realizes the heat dissipation of the overall shell in the heat dissipation structure. The internal and external multi-rib structure greatly increases the heat dissipation surface. The temperature rise of the whole lamp is within 15 degrees after 24 hours of lighting, which can effectively ensure the use of LEDs. Life and light decay are optimally controlled.

4. Lenses are often ignored by some designers. In fact, the refraction of light will cause light loss, and the transparent lens rate also profoundly affects the final output luminous flux. At present, lenses with better light transmittance can reach more than 93. Lenses are also a relatively important cost, so some factories use cheap lens materials in order to save costs. They must be secondary materials. The light transmittance is about 70. It will not be obvious to the naked eye to deceive consumers, but it is easy to use instruments. The test results show that the lens with poor material will turn yellow and other bad results after using it for a long time. Ocean King Explosion-proof adopts the unique patented technical scheme in the light distribution scheme, the light distribution according to the diffuse reflection light distribution principle, can achieve the LED reflection output rate of more than 98%, fully realize the effective light reflection and improve the effective illuminance value.
