LED explosion-proof lights related information

Drive power: LED is a semiconductor component that converts light energy by DC electrons. Therefore, a stable drive requires a high-performance power driver chip. At the same time, the power factor pu compensation function is required to ensure the power supply efficiency. The power supply is crucial for the entire lamp. The factors, and currently on the market led power quality uneven, mixed fish and dragon, a good drive power is not only to ensure a stable DC supply, but also fully guarantee the improvement of conversion efficiency, this parameter reflects the real lighting Energy saving. The safe and explosion-proof LED luminaires are all designed using high-efficiency power supply schemes, multiple protection functions, and the target values ​​of the output effective power are all set at not less than 95%. The output power of the explosion-proof floodlights achieves a conversion rate of 98%, which is an industry-leading level. .

LED light source: high-brightness, high-efficiency and low-light-emitting LED chips must be used, and the packaged gold wire/phosphor powder/insulation glue, etc. must all meet the requirements. Safe and explosion-proof professional production of industrial lighting, the product covers the lamps used in professional fields and explosion-proof lighting used in various types of explosion-proof area, high quality assurance rate, the use of the aluminum substrate is the use of domestic advanced film composite 2.0 coefficient High thermal conductivity aluminum substrate. It plays an important role in the service life of the LED.

LED lamp appearance structure of the cooling system, an excellent lighting in addition to the appearance of high-end appearance, high-quality light source and power supply, but also more important is the rationality of the structure of the shell, which involves the cooling problem of led lamps, due to LED conversion light energy At the same time, there is also a part of the electrical energy into heat, it is necessary to lead the heat out to the air, so as to ensure that the led stable light, high temperature of the led lamp will cause light decay to accelerate the life of the led lamp. It is worth mentioning that the technology of LED chip is continuously improving, and the conversion efficiency is also improved. The amount of electricity used to convert heat will be less, the radiator parts will be used thinner, and the costs will be reduced, which will be beneficial to the promotion of LED. This is just a direction of technological development. At present, the heat dissipation of the enclosure is still a parameter that must be considered. The BC9700 high-power LED explosion-proof lamp completely realizes the heat dissipation of the overall shell components. The multiple ribs structure inside and outside makes the heat dissipation surface greatly increased. The temperature rise of the entire lamp is within 15 degrees after 24 hours, which can effectively guarantee the LED use. Lifetime and light decay are optimally controlled.

LED light lens is also often ignored by some designers, in fact, light refraction will produce light loss, the lens rate actually affects the final output of the light flux, the current transmittance of the lens can reach more than 93, Since the lens is also a relatively important cost, some manufacturers use cheaper lens materials to save costs. It must be a secondary material. The light transmittance is about 70. It is not easy to see how to use the naked eye to deceive customers, but its practical instruments are It is easy to test the results, the lens with poor material, and the result of the yellowing and other undesirable results. The unique patented technical solution chosen by Ping's explosion-proof light distribution scheme and diffused light distribution principle can achieve LED retro-reflection output rate of more than 98%, and fully realize effective light reflection to increase effective illumination value.

Steel Mills Roller Bearing

Rolling Mill Bearing for blanking machine .
Rolling mill bearings are the bearings used on the roll necks and rollers of metallurgical, mining and other rolling mill stands. Cylindrical roller bearings are often used to withstand radial loads, deep groove ball bearings or angular contact ball bearings, or radial design or thrust design Tapered Roller Bearings to withstand axial loads. Most of them are lubricated and cooled by means of oil-air lubrication or oil mist lubrication.
Rolling Mill Main Application:
Cold rolling mill, Hot rolling mill, Blanking machine
