a. Long life of light source (9000-15000 hours)
In general, the lifetime of low-power quartz metal halide lamps is between 6000 and 9000 hours, and ceramic metal halide lamps have the above-mentioned advantages, so their lifetime can reach 9000-15000 hours, which is 30% higher than that of traditional quartz metal halide lamps. 50%;
b, higher luminous efficiency (%26gt; 90 lm/w)
At present, due to the global energy crisis, people attach great importance to the effective use of energy. In the lighting industry, the concept of green lighting is proposed in response to the effective use of energy. Therefore, although tungsten halogen lamps and incandescent lamps have excellent color rendering properties, they have serious thermal energy loss during ignition and have a short life span, which is obviously not an ideal green lighting product. The high light efficiency of ceramic metal halide lamps can improve energy use more effectively and reduce the cost of owners. The efficiency of the metal halide lamps is four to nine times higher than that of halogen lamps and incandescent lamps. At the same time, the performance of light and color is far away. Better than quartz metal halide lamp, it is a new light source that combines excellent light color performance and high luminous efficiency.
c. The color temperature stability during life is good (between +/-200K), and the color temperature consistency between the light sources is better
Ceramic metal halide lamp from the ignition, until the end of life, its color temperature changes within 200K, and the general color temperature of the quartz metal halide lamp during the life of the color change is greater than 600K, so the ceramic metal halide lamp to solve the color difference of the quartz metal halide lamp and Color temperature drift problem;
d, stable lumen output
The lumen output of a light source can decay over time. The lumen output of ceramic metal halide lamps is the highest among low-power metal halide lamps. The lumen output at the beginning of life is 10-20% higher than that of ordinary quartz metal halide lamps. More importantly, it maintains this level of performance. The light source output until the end of life. The lumen maintenance rate of ceramic metal halide lamps is above 80%, while that of quartz metal halide lamps is 60-65%, and its light decay is faster.
e, light source geometry is more compact
Lamps and electrical appliances that are compatible with current quartz metal halide lamps are easy to promote and apply. And because its light is smaller, it is conducive to the design of lamps and lanterns. It is more convenient to control the lights.
f, with 3000K and 4200K two color temperatures to choose from, light source color rendering (Ra 80-90) color rendering quality is also related to the arc tube wall temperature. In general, the higher the wall temperature, the better the color rendering. The arc tube wall temperature of the ceramic metal halide lamp can reach 1150 degrees, while the arc tube wall temperature of the quartz metal halide lamp can only reach 800 degrees, so the color rendering of the ceramic metal halide lamp is much better than the quartz metal halide. light. At the same time, the wall temperature also affects the color temperature difference of the light source. As we have just mentioned, quartz metal halide lamps can only reach 800 degrees because their maximum tube wall temperature, and the wall temperature is inversely proportional to the temperature difference with the color, so the final color temperature difference is larger than the ceramic metal halide lamp.
