Explosion-proof LED light installation should also be checked before

Explosion-proof LED lamps are widely used lighting fixtures, and their explosion-proof technical problems have already attracted widespread attention and great attention. The aluminum alloy shell is selected, and the surface is sprayed with plastic; it can be used for lighting and emergency.

Before explosion-proof lamps did not appear, many enterprises installed general lamps. Because ordinary lamps did not have good explosion-proof performance, some factory accidents occurred frequently, which caused serious loss of enterprises. The factory simply produces flammable and explosive materials during production. Because the lighting fixtures inevitably generate electric sparks or form hot surfaces during operation, they encounter explosive gases and ignite these gases, resulting in explosions. Explosion-proof lamps have the function of isolating flammable gases and dust. In these risky places, it can avoid sparks and high temperatures inside the lamp to ignite flammable gases and dust in the surrounding environment, and then meet the explosion-proof requirements.

Built-in protection-free nickel-cadmium battery pack, active charging under normal power supply, active lighting of emergency lights in case of power failure or power failure; steel pipe wiring; normal lighting and emergency lighting in emergency special lights are independent; emergency dual-purpose lights, normal lighting It shares a lamp body with emergency lighting, and the light source is independent.

Before installing the LED ceiling lamp, it should also be checked: the cross-section of the wire core leading to each lamp, the copper core flexible wire is not less than 0.4mm², and the copper core is not less than 0.5mm², otherwise the lead wire should be replaced. The connection between the wire and the lamp cap, and the connection of the parallel wire between the lamp caps should be firm, and there is a risk of sparks between the wires and the terminals.

Teach children not to throw balloons and other objects at the lamps indoors, so as to avoid the decorations hanging on the lamps from falling and hurting people or affecting the decoration effect of the lamps. , The light bulb is made according to the principle of thermal effect of electric current. After the bulb is connected to extra voltage, the current passes through the filament and is heated to an incandescent state (above 2000C), so it emits heat. Thus, during operation, 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.
