Classification of chandelier light source in lobby of water-saving faucet hotel

Incandescent lamps are equipped with tungsten filament, with luminous efficiency of 10 ~ 15 flow/watt, color temperature of about 2800, good color rendering, and rated life of 1000 hours, 220 volts, 15 watts and 220 volts, 1000.

There are two kinds of lamp holders: screw type and bayonet type.

Reflective incandescent lamps emit light beams directionally, with high utilization rate of light energy, and are generally used in windows, exhibition halls and places where spotlight lighting is needed.

Tungsten halogen lamp tungsten halogen lamp is filled with a certain amount of iodine and bromine or their compounds.

Tungsten halogen lamp uses the chemical reaction principle of tungsten halogen cycle, which greatly reduces the evaporation of tungsten wire and the blackening of bulb.

The luminous efficiency and rated life of tungsten halogen lamps are higher than those of incandescent lamps.

Tungsten halogen lamps are often made into tubes with small volume, power of 300 ~ 1000 watts, color temperature of 2800 ~ 2900 kelvin, good color rendering, rated life of about 1500 hours and stable luminous flux.

Mostly used for indoor and outdoor large-area lighting.

Fluorescent lamp Fluorescent lamp is also called fluorescent lamp.

Different fluorescent substances will emit different visible light.

Generally, the efficiency of converting ultraviolet light into visible light is about 40%.

Therefore, the efficiency of fluorescent lamps is about 60% × 40% = 24%, which is about twice that of tungsten lamp with the same power.

Energy-saving lamps Energy-saving lamps are also called compact fluorescent lamps (CFL lamps abroad).

It has the advantages of high light efficiency, obvious energy-saving effect, long service life, small size and convenient use.

Generally speaking, under the same wattage, energy-saving lamps save 80% more energy than incandescent lamps, prolong their average life by 8 times, and radiate only 20%.

Under non-strict conditions, a 5-watt energy-saving lamp can be regarded as a 25-watt incandescent lamp, a 40-watt 7-watt energy-saving lamp and a 60-watt 9-watt energy-saving lamp.

LED lamp LED lamp, also called light emitting diode, is a solid-state semiconductor device.

Small size, low power consumption, long service life, non-toxic and environmental protection and many other advantages.
