1. Light source: LED chips with high brightness, high light efficiency and low light decay must be used. This requires the selection of LED lamp beads packaged by conventional channel chips from brand chip manufacturers such as Corey in the United States and Osram in Germany, and packaged with gold wires/phosphors. / Insulation glue, etc. need to use materials that meet the requirements. Chuanwang explosion-proof professional production of industrial lighting. The products cover lamps used in professional fields and various explosion-proof lighting lamps used in explosion-proof fields. The use of LED explosion-proof lights all use the internationally renowned brand OSRAM LED. The quality assurance rate is quite high. The aluminum substrate adopts the domestic advanced plastic film composite 2.0 coefficient high thermal conductivity aluminum substrate. It plays an important role in the lifespan of the LED.
2. Driving power: LED is a semiconductor component that converts DC electrons into light energy, so stable driving requires high-performance power driver chips, and requires power factor pu compensation function to ensure power supply efficiency. The most important factor is that the quality of LED power supply on the market is uneven, and the quality of LED power supply is uneven. A good drive power supply can not only ensure stable DC power supply, but also fully guarantee the improvement of conversion efficiency. This parameter reflects the real energy saving of lighting and waste to the grid. The LED lamps used by Chuanwang 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 to not less than 95%. The output power of LED floodlights has reached a conversion rate of 98%, which is an industry-leading level.
3. The cooling system with compact appearance, in addition to high-end and elegant appearance, high-quality light source and power supply, an excellent lamp is more important to the structural rationality of the shell, which involves the dissipation of heat LED lamps, because LED conversion light energy. At the same time, a part of the electrical energy is also converted into heat energy, which needs to be extracted and dissipated into the air to ensure the stable light emission of the LED. It is worth mentioning that the technology of LED chips is constantly improving, and the conversion efficiency is also constantly improving. The power consumption of thermal conversion will be less, the heat dissipation components will be thinner, and some cost reductions will also be beneficial to the promotion of LEDs, but this is only a technical development direction. At present, the heat dissipation of the casing is still a parameter that must be studied. The BC9700 high-power LED explosion-proof lamp completely realizes the heat dissipation of the overall shell in the heat dissipation structure. The inner and outer multi-rib structure greatly increases the heat dissipation surface. After 24 hours of lighting, the temperature of the whole lamp is within 15 degrees, which can effectively ensure the use of LED. Lifetime and light decay are optimally controlled.
4. Lenses are often overlooked by some designers. In fact, the refraction of light will cause the loss of light, and the transmittance also profoundly affects the final output luminous flux. At present, lenses with better light transmittance can reach above 93. Lenses are also a relatively important cost, so some factories use cheap lens materials in order to save costs. They must be auxiliary materials. The light transmittance is around 70, the naked eye will not deceive consumers obviously, but it is easy to use the instrument. The test results show that the lens with poor material will turn yellow and other bad results after using it for a long time. Chuanwang Explosion-proof adopts a unique patented technical scheme in the light distribution scheme. According to the principle of diffuse reflection light distribution, the light distribution can reach more than 98% of the LED reflection output rate, fully realize the effective light reflection, and improve the effective illuminance value.
