(MENAFN- Market Press Release) April 1, 2024 3:29 am - This blog will introduce the use of incandescent lamps and the principle of operation and other precautions for use. I hope you understand the knowledge of incandescent lamps, after the use of more comfortable in daily life.
Incandescent lamp is a thermal radiation light source, the conversion efficiency of energy is very low, only 2% to 4% of the electrical energy is converted to the eye can feel the light. However, incandescent lamps have good color rendering, spectral continuity, ease of use and other advantages, and therefore is still widely used.
This blog will introduce the use of incandescent lamps and the principle of operation and other precautions for use. I hope you understand the knowledge of incandescent lamps, after the use of more comfortable in daily
1 use of incandescent lamps
Incandescent light efficiency is low, but the light color and light collection performance is good, easy to mass production, low cost, easy to use. Therefore, it is always the largest production, the most widely used electric light source. In addition to general lighting, but also for aviation, vehicles, ships with lights, medical and health, instruments, signal indicators, stage, projection, photographic lights, infrared heating, mining, agriculture and photometric standard
2 working principle of incandescent lamp
Current through the filament (tungsten filament, melting point of more than 3,000 degrees Celsius) when the heat, spiral filament will continue to gather heat, making the filament temperature of 2,000 degrees Celsius or more, the filament in the incandescent state, as if red-hot iron can emit light. The higher the temperature of the filament, the brighter the light emitted. It is called incandescent lamp.
3. Incandescent lamp maintenance method
Regular replacement of old bulbs --- incandescent bulbs in the service life of 80%, the output beam is reduced to about 85%, so it is appropriate to replace before the end of life.
Do not switch on and off frequently --- this is to protect the incandescent bulb life is very critical point, repeated heating of the filament will accelerate aging.
Ceiling, wall use light color --- can increase the reflection of light, improve the effect of light diffusion to save energy.
Regular cleaning of lighting equipment --- lamps and lanterns have not been cleaned for a long time, easy to make the dust accumulated in the lamp, affecting the output efficiency, so it is recommended that at least 3 months to clean the lamps and lanterns.
Ordinary incandescent lamps are mainly composed of glass shells, filaments, filament guides, core columns, heads, etc. For different uses and requirements of incandescent lamps, the structure and components also vary. Glass shell is generally made of good heat-resistant soda-lime glass, high-power incandescent lamps need to use better heat-resistant borosilicate glass, with special purposes will be used in colored glass. Seemingly ordinary glass shell, the role is not to be underestimated. Glass shell not only play a role in transmitting light and prevent users from scalding, but also the filament and the outside world air isolation, can reduce the filament oxidation at high temperatures, to extend the service life of the filament.
4. Advantages and disadvantages of incandescent lamps
The advantages of incandescent light is soft and uniform light, it is the light color is the closest to the sun's color, color temperature is usually between 2700K and 4000K, the human eye is easier to receive. Good color rendering, can better restore the object's original color. The disadvantage is the use of short life, about 1000 hours.
