With the increasing awareness of energy saving, a new generation of gas discharge lamp replaces incandescent lamp. The color temperature of gas discharge lamp source and that of thermal radiation lamp source are two completely different concepts. The color temperature of gas discharge light source is not only related to temperature, but also related to the uniformity of temperature distribution, the types of fillers, the proportion of elements, the types and properties of outer vesicle phosphors. This paper mainly analyses the related theory knowledge of color temperature of metal halide lamp.
The first factor affecting the color temperature of 315w ceramic metal halide lamp is the cold point temperature.
The second factor affecting the color temperature of 315w metal halide lamp is halide filler. It requires different specifications of arc tubes with the same color and temperature. Because the tube wall temperature is different, different sodium content pills are needed. At the same color temperature, the higher the wall temperature is, the less sodium content is required. With the wrong pill, the color temperature will change naturally. The improper exhaust process will lead to the evaporation of metal halide pills. The improper storage, transportation or use of the pills will change the color temperature.
The third factor affecting the color temperature of 315w ceramic metal halide lamp
is external sealing. The type of the inflatable body, the size and shape of the bubble shell and the inflatable pressure are related.
