The structure of the LED explosion-proof lamp is not as simple as everyone\'s phenomenon. The following LED explosion-proof lamp manufacturers will summarize the structure of the LED explosion-proof lamp for everyone, and hope it will be helpful to everyone.

1. Panel light aluminum frame:

   is the main channel for the heat dissipation of the LED explosion-proof lamp, and the appearance is simple and generous. There are two main types: one is the low cost of die stamping and mold opening, and the processing cost is also low. The other is a die-cast aluminum frame. This type of surface has good surface texture and overall appearance, but the cost of investing in molds in the early stage is relatively high.

   2. LED explosion-proof light source:

   Usually the LED lamp beads of the LED explosion-proof lamp use 3528, and some people use 3014 and 5050. The cost of 3014 and 5050 is low, and the light efficiency is slightly worse. The key is that the design of the light guide network is difficult. 3528 has high luminous efficiency and good dot versatility.

  3. Light guide plate of LED explosion-proof lamp:

  The side LED light is refracted through the dots so that the light is uniformly led out from the front. The light guide plate is the key point of the quality control of the LED panel light. If the dot design is not good, the overall light effect seen is very poor. Generally, there will be dark on both sides of the light in the middle, or there will be bright light bands at the light entrance, or there may be partial dark areas, or there may be inconsistent brightness at different angles. To improve the light efficiency of the light guide plate mainly depends on the design of the dots, followed by the quality of the plate, but there is no need to be superstitious about the first-line brand-name plates, and the light transmittance between qualified plates is usually the same. Generally, small LED lamp factories directly buy public light guide plates for use, so there is no need to re-proof the design, and the public version used by many manufacturers is usually of good quality.

  4. LED diffuser:

   leads the light of the light guide plate uniformly, and can also play the role of blurring the dots. Diffusion plates generally use acrylic 2.0 sheets or PC materials, almost PS material, acrylic has a lower cost and a slightly higher light transmittance than PC, acrylic is brittle and has weak anti-aging properties, and PC is slightly expensive, but it has anti-aging properties Strong. After the diffuser is installed, the dots cannot be seen, and the light transmittance should be around 90%. The light transmittance of acrylic is 92%, PC is 88%, and PS is about 80%. You can choose the diffuser material according to your needs. At present, most manufacturers use acrylic materials.

   5. Reflective paper:

   Reflect the remaining light on the back of the light guide plate to improve light efficiency.

  6. Rear cover:

   The main function is to seal the LED panel light, which is generally made of aluminum, which can also play a role in heat dissipation.

  7. Drive power:

   There are currently two kinds of LED driving power supplies for LED explosion-proof lights, one is to use a constant current power supply, this mode has high efficiency, PF value up to 0.95, and high cost performance. The other is to use constant voltage with constant current power supply, which has stable performance, but low efficiency and high cost. Generally, this power supply is mainly used for export. The other party requires certification requirements and must use a safety-related power supply. In fact, it is very safe to use a constant current power supply at home, because it is difficult for users to access the power supply, and the lamp body itself uses safe low-voltage electricity.

   8. Install the pendant:

   Suspension wires, mounting brackets and other accessories used to install and fix.
