1Light source bulbType and Application

1. Incandescent lamp

Features: Good color rendering (Ra=100), lights up immediately when turned on, continuously dimmable, simple structure, low price, but short lifespan (about 1000 hours), low light efficiency (10-17 lm/W).

Application scenarios: Local lighting in living rooms, living rooms, lobbies, guest rooms, shops, restaurants, corridors, conference rooms, courtyards, and other areas.

2. Halogen tungsten lamp

Features: Filled with halogen elements or halides, the light efficiency and lifespan are more than twice that of incandescent lamps, the size is small, and it is resistant to high temperatures.

Application scenarios: conference rooms, exhibition halls, living rooms, commercial lighting, film and television stages, instrumentation, automobiles, airplanes, and other special lighting.

3. Fluorescent lamps (fluorescent lamps)

Features: High luminous efficiency (50-100 lm/W), long lifespan (6000-15000 hours), good light color, and needs to be used in conjunction with a ballast.

Application scenarios: Straight tube type is suitable for indoor and outdoor lighting (such as offices, shopping malls), compact type is suitable for homes, corridors, etc.

4. Low pressure sodium lamp

Features: High luminous efficiency (up to 200 lm/W), strong fog transmission, but poor color rendering (Ra ≈ 20).

Application scenarios: tunnels, ports, docks, mines, and other places that require high brightness and fog transparency.

5. High intensity gas discharge lamp

Fluorescent high-pressure mercury lamp: Long lifespan (about 10000 hours), low cost, suitable for road and industrial lighting.

High pressure sodium lamp: high luminous efficiency (100-150 lm/W), strong fog transmission, suitable for road, square, and industrial lighting.

Metal halide lamp: Good color rendering (Ra ≥ 80), high luminous efficiency, suitable for sports venues, commercial lighting, and urban lighting.

6. High frequency infinite lamp

Features: Ultra long lifespan (40000-80000 hours), no electrodes, instant start, no flicker.

Application scenarios: public buildings, tunnels, high pole streetlights, security lighting, etc.

7. Halogen bulb

Features: Longer lifespan than incandescent bulbs (2000-4000 hours), higher brightness and efficiency, requiring the use of quartz glass.

Application scenarios: automobiles, airplanes, commercial displays, film and television lighting.

8. LED lights

Features: Low voltage (6-24V), safe, long lifespan (over 50000 hours), high light efficiency (80-150 lm/W), good color rendering (Ra ≥ 80), environmentally friendly and mercury free.

Application scenarios: Home, commercial, industrial, road lighting, etc., supporting intelligent control (such as dimming, color temperature adjustment).
