LED is called the fourth generation of energy-saving lighting products, environmental protection: no mercury, no ultraviolet light. Energy Saving: High luminous efficiency, the current mass production reaches 160lm/w. Long life: 70% lumen maintenance life of 36,000 hours. Not afraid of vibration, can achieve dimming, intelligent control.
Metal halide lamps belong to high gas discharge lamps. They have a small area of ​​light emitters, light gathering, long irradiation distance and strong penetrating power. However, they have slightly poor light color, slow start-up and high UV content, and are suitable for use in roads, stadiums and other higher places.
Detailed technical terms
â— own power consumption
Due to the use of an inductive ballast, metal halide lamps have high power consumption and high operating current. They have a very high starting current at the moment of starting. For example, 400W gold halide has an instantaneous current of up to 15A at the start-up, which has a great impact on the life of the appliance and often causes damage. Air switch facility. At the same time, the ballast itself consumes a large amount of electric energy, causing huge electricity expense to the user and accelerating the aging time of the line; the LED uses a constant current driver, has low power consumption, and has a high power factor to avoid the above problems.
â—Color rendering index
It is an important parameter to measure the visual quality of light sources. The color rendering index is high. Under the lamp, it is clear to see things and the colors are true. On the contrary, it is not clear to see things under the lights, the light is blurred, and the objects are distorted. Metal Halide 65, low color rendering index. Working under these light sources can easily cause myopia and visual fatigue.
â— UV content
Ultraviolet rays are a terrible light that can cause serious damage to the eyes and skin, causing eye disease and skin cancer. The ultraviolet content of traditional light sources is very high, such as metal halide lamp UV content of 34% of the total luminous flux, long-term work under the metal halide lamp will cause considerable damage to the human body, LED does not contain ultraviolet light.
â— Repeated startup capability
After the metal halide lamp is turned off, it needs to wait for a period of 10 minutes before it can be started again. Otherwise, it will be burned and it will cause inconvenience for use.
â– Glare
Is a kind of light pollution, it is due to the light source itself or the light source and the lamp is not properly matched. Working under glare can cause visual fatigue and visual errors. It is also a major cause of myopia. Metal halide lamps cause the light to be refracted due to uneven manufacture of glass bulbs, and therefore their glare is very serious, and they are point light sources, and it is easy to form a focus with the luminaire to cause glare.
â– Strobe
It is a kind of light pollution, which is caused by the periodical change of the alternating current voltage due to the luminous flux of the point light source. Strobe is the "invisible killer" of the lighting environment, causing myopia and migraine headaches. The strobe of a metal halide lamp is very serious. People's eyes can feel the flashing of light, which is very harmful to the human visual system. The LED does not flicker because it rectifies the alternating current into a direct current, and the voltage of the direct current does not change periodically.
