What are the types of incandescent bulbs? Advantages of incandescent lamps
The incandescent lamp is a generation of lamps after the invention of the lamp. The invention of lamps has brought major changes to people's lives. Incandescent lamps have played an indelible effect on people with the growth of the post-80s. As energy-saving lamps have entered thousands of households, although incandescent lamps have disappeared, their light is still in people's hearts. So, what are the types of incandescent bulbs? As well as the advantages of incandescent lamps, let's take a look.
What are the types of incandescent bulbs
1. Ordinary incandescent lamps are commonly used incandescent bulbs
Features: Good color rendering (Ra=100), bright when the lamp is turned on, continuous dimming, simple structure, low price, but short life and low light efficiency. Uses: bedroom, living room, lobby, guest room, shop, restaurant, walkway, meeting room, courtyard. Usage: table lamp, ceiling lamp, wall lamp, bedside lamp, corridor lamp.
2. Fluorescent light
Fluorescent lamps are commonly known as fluorescent lamps. Features: high luminous efficiency, long life, and good light color. Fluorescent lamps have straight tube type, ring type, compact type, etc., which are energy-saving lighting sources with a wide range of applications.
3. Tungsten halogen lamp
A gas-filled incandescent lamp with some halogen elements or halides in the filling gas. It has all the characteristics of general lighting incandescent lamps, the light efficiency and life span are more than double that of general lighting incandescent lamps, and the volume is small. Uses: meeting rooms, exhibition halls, living rooms, commercial lighting, film and television stages, instrumentation, automobiles, airplanes and other special lighting.
4. Low pressure sodium lamp
Features: extremely high luminous efficiency, long life, high luminous flux maintenance rate, strong fog permeability, but poor color rendering. Uses: lighting for tunnels, ports, docks, mines, etc.
Advantages of incandescent lamps
1. Good color rendering, soft light color
The color rendering of incandescent lamps is particularly good, and its color rendering is as high as 95-99, which is close to natural light. It is very suitable for lighting in occasions that require good color discrimination conditions (such as art galleries, merchandise showcases, etc.).
2. The light is very uniform
Secondly, the light emitted by the incandescent lamp is soft and uniform. The spherical glass shell can evenly transmit light and emit light in all directions at 360 degrees, which can magnify the brightness of the bulb.
3. Easy to dimming
Furthermore, incandescent lamps can easily control the changes of different brightness of the light. The brightness can be adjusted by directly changing its input voltage, which is very suitable for dimming places.
4. Low package temperature
The incandescent lamp light is reddish-yellow, and the color temperature is 2700~2900K. It will make people feel comfortable under low illumination. Therefore, incandescent lamps are very suitable for bedroom, living room: and other living room lighting.
5. Good starting performance
After the incandescent lamp is ignited, the light output of the lamp reaches the rated value quickly, and no start-up time is required. This is very important for life lighting and emergency lighting, and is one of the advantages of incandescent lamps.
6. Simple and convenient maintenance
Incandescent bulbs are easy to replace, no professional electricians are required, and ordinary residents can maintain and replace them by themselves. They only need to twist lightly, connect the lamp holder to the wire bayonet and it is OK.
The above is a brief introduction to all the types of incandescent bulbs and the advantages of incandescent bulbs. I hope it will be helpful to everyone.
