DeutscheWe all know a kind of led garden light in the yard, its lifespan is slowly shrinking, until one day it completely goes out and then dies. Many people are inevitably confused, why does the lamp have such a process, and what causes it? In fact, in the final analysis, this is the problem of light decay of lamps and lanterns. Simply put, lamps and lanterns are the same as the human body. With the increase of service life, the functional mechanism of lamps and lanterns continues to decline. Whether it is incandescent, fluorescent or LED lamps, the problem of light decay can be avoided.
The light decay of lamps and lanterns means that the light intensity of the lamps is lower than the original light intensity after a period of time, and the reduced part is the light decay of the lamps. Different types of lamps cause different causes of light attenuation.
Incandescent bulbs for led garden light lighting fixtures
For ordinary incandescent lamps, the larger the bubble envelope, the less the light attenuation, which is proportional to the evaporative deposition of tungsten, preventing the light output. Gas-filled bulbs lose less light because some of the gas prevents the tungsten filament from evaporating.
If incandescent lamps are made from the same filament, the bulbs are different sizes, then the light attenuation at the same point in time in a large bulb is indeed less than in a small bulb. In addition, it is also a gas-filled bubble. The bulb with a large glass shell has a larger internal space, and the gas convection with the glass shell has a larger heat dissipation area. The temperature of the relatively small glass shell lamp is much lower, and the temperature of the filament is also relatively small. Low, the luminous efficiency is low, the evaporation rate of the tungsten wire is low, so the light attenuation is small.
