Lamp light source is also the lighting source, which refers to the artificial light source used for lighting inside and outside the building. So what are the types of light sources? In simple terms, it is generally divided into three categories: thermal radiation light sources, gas discharge light sources and semiconductor light sources. There will be more products. What are the main types of lamps? Don't worry, the following Jiuzheng Lighting Network will explain it for everyone, let's take a look.

Lamp light source type:

Thermal radiation source
It is made by the principle of radioluminescence when the object is heated to a high temperature. This type of lamp has a simple structure and is convenient to use, and can be used when the rated voltage of the bulb is the same as the power supply voltage.

Gas discharge light source
It is made using the principle of light emission when electric current passes through gas. This kind of lamp has high luminous efficiency, long life and many kinds of light colors.

Semiconductor light source
Including phosphors that emit light under the action of an electric field, or semiconductor p-n junctions. This type of lamp is only used in places that require special lighting.

What are the main product types of lamps?
Incandescent lamp
The incandescent lamp is equipped with tungsten filaments, the luminous efficiency is 10-15lm/w, the color temperature is about 2800K, the color rendering is good, and the rated life is 1000 hours. China has a series of products with different power from 15w to 1000w. There are two types of lamp holders: screw type and bayonet type. It is often used for indoor general lighting, but also for outdoor lighting with lower illuminance requirements. Reflective incandescent lamps emit directional light beams and have high light energy utilization. They are generally used in shop windows, exhibition halls and places that require spotlighting.

Tungsten halogen lamp
Tungsten halogen lamps are equipped with tungsten filaments and filled with a certain amount of iodine and bromine or their compounds. Tungsten halogen lamps use the principle of tungsten halogen cycle chemical reaction, which greatly reduces the evaporation of tungsten filaments and the blackening of the bulb. The luminous efficiency and rated life of tungsten halogen lamps are higher than that of incandescent lamps. Tungsten halogen lamps are often made into tubes, small in size, power 35w～1000w, color temperature 2700～3300k, good color rendering, rated life of about 1500 hours, stable luminous flux. Mostly used for indoor accent lighting.

Fluorescent lamp
Fluorescent lamps are good indoor lighting sources. The luminous efficiency is much higher than that of incandescent lamps, generally 30-60lm/w, and high luminous efficiency can reach 90lm/w. The light colors of fluorescent lamps are daylight, cool white and warm white. The high color-rendering fluorescent lamp uses three-primary color phosphors, the color rendering index can reach more than 80, and the life span is 1500-5000 hours. Corresponding ballast and starter should be equipped when in use. High color rendering fluorescent lamps are mostly used for lighting in printing and dyeing factories, printing plants, shopping malls and TV studios with high color rendering requirements. The power of the straight tube fluorescent lamp ranges from 6w to 40w, up to 125w. This kind of lamp is most suitable for lighting in architectural halls, large shops and precision processing workshops. In order to improve the lighting performance, special-shaped fluorescent lamps (such as circular fluorescent lamps) can be used as the light source. Newly created compact energy-saving fluorescent lamps with small size and high luminous efficiency are also widely used in indoor lighting.
