Speaking of halogen lamps, I think everyone is familiar with it. It can be seen not only in some home decoration, but also in some cars. Before led lights appeared, most cars used halogen lamps. So what are the precautions for the use of halogen lamps and what are the advantages of halogen lamps? Let's take a look with Xiaobian!

What should I pay attention to when using halogen lamps?

1 Before installing the halogen lamp, we need to turn off all the power supply, and then use the plastic sleeve to protect the glass shell of the bulb. You can't touch it directly with your hands. If you touch it carelessly, please wipe it clean with alcohol.

2. Halogen bulbs are made of high-temperature resistant Shi Ying glass. If they are contaminated with oil, Shi Ying glass will lose its luster and become turbid, which will reduce its brightness, shorten its life, and even break the glass shell. Therefore, attention should be paid to maintenance and cleanliness when using it.

3. When the halogen bulb is used for lighting, the temperature at the seal should not exceed 350 degrees, otherwise it will affect the life of the halogen bulb, so the halogen lamp must be well ventilated and cooled.

4. When lighting the halogen bulb, avoid cold air blowing directly to the bulb, and avoid being impacted or shaken during the lighting process. In addition, after lighting the halogen bulb or just turning off the lights, do not touch it with your hands to avoid scalding your hands.

What are the advantages of halogen lamps?

1, halogen bulb is also called halogen bulb or halogen lamp, also known as tungsten halogen bulb and quartz bulb, which is a kind of incandescent lamp.

2. The working principle of halogen lamp is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten filament reacts with halogen, and the cooled tungsten will solidify on the tungsten filament again, forming a balanced cycle to avoid premature fracture of the tungsten filament, so the halogen bulb has a longer life than incandescent lamp. The luminous principle of all incandescent lamps is realized by using the principle of object being heated to emit light and the principle of thermal radiation. The simplest incandescent lamp is to turn on enough current to the filament, and when the filament is heated to incandescent state, it will emit light, but the life of this incandescent lamp will be quite short.

3. Halogen lamp has many advantages: its shape is simple, its cost is low, its brightness is easy to adjust and control, its color rendering is good (Ra= 100), etc., but it also has some fatal disadvantages: for example, its service life is short, its luminous efficiency is low, and its color temperature is low (2700-3 100K).
