According to the lighting needs of the scene, confirm the installation location and method of lamps and lanterns
Explosion-proof lighting manufacturer vertical boom type equipment: Explosion-proof lighting first pass the connector through the cable, screw it into the steel pipe, tighten the set screw, and then pass the cable through the gasket and the sealing ring in sequence until it is inside the junction box (reserved for A certain length of cable is convenient for wiring), then tighten the lamp body and the connector, and tighten the set screw;
Ceiling-mounted equipment: screw the 3/4-inch adapter into the ceiling-mounted adapter, screw the connector into the 3/4-inch adapter, tighten the set screws separately, and then pass the cables, the equipment is on the roof, and pass the cables in sequence. Pass the gasket and sealing ring to the junction box (reserve a certain length of cable to facilitate wiring), then tighten the lamp body and the connector, and tighten the set screw.
The light bulb is made according to the principle of the thermal effect of electric current. After the bulb is connected to the rated voltage, the current passes through the filament and is heated to an incandescent state (above 2000C), so it generates heat and emits light. Thus, when working, the electrical energy is converted into internal energy and light energy.
And one way light is energy is released by atoms. It is made up of many clumps of tiny, similar particles that have energy and momentum but no mass. These particles, called visible photons, are the basic unit of light. Atoms emit visible photons when electrons are excited. If you already know how atoms work, you also know that electrons are negatively charged particles that move around the nucleus. The electrons of an atom have different levels of energy, depending on several factors, including their speed and distance from the nucleus.
According to the on-site lighting requirements, confirm the installation position and method of the lamps, and then prepare the three-core cable of the corresponding length according to the distance from the lamp to the lamp (if the steel pipe is used for wiring, the three-core cable is introduced into the steel pipe to the lamp installation).
First remove the fixing screw on the wiring cavity, and pull out the wiring part of the junction box; take out the sealing ring and the connector (with the set screw) from the packing box, and insert the cable in sequence; then connect one end of the three-core cable separately. Mark the "L", "N" and the grounding place in the box. After pressing the cable with the crimping clip, fix it with the fastening screw, then tighten the joint, press the sealing ring, and fasten the fastening screw from the side.
