The characteristics of LED, the light was called the fourth generation of energy saving lighting products, environmental protection, no mercury, no ultraviolet light.
Energy saving: high light efficiency, current production reached more than 180 lm/w.
Long life: 70% optic retention lifetime of 100000 hours.
Not afraid of vibration, can realize the dimming,
the characteristics of light emitting diode, light was called the fourth generation of energy saving lighting products, environmental protection, no mercury, no ultraviolet light. Energy saving: high luminous efficiency, the batch production reached more than 180 lumens/watt. Long life: optical communication maintenance rate 70% life over 100000 hours. Not afraid of vibration, dimming and intelligent control can be realized. Metal halide lamp belongs to the high gas discharge lamps, light emitting area is small, light, long distance, strong penetrating power, but the light color is a bit poor, slow start, high content of ultraviolet light. two The comparison of leds and metal halide lamp indicator. Performance indicators leading metal halide light flux 180 mm/w80 mm/tile color rendering index more than 75 years old, start time instant 5 - about 65 years old Ten minutes uv content 34%, not suitable for close range gate under power frequency does not work, feel stroboscopic serious to the naked eye. Dazzling glare not serious height 6 - operation 15 m more than 8 m suitable location is super, factory, warehouse, garage, outdoor life etc and high dome light outdoor places more than 100000 hours and ten thousand hours of power factor is higher than 0. About 0, 95. 8 low starting current is very high, it has a great influence to the appliance. 85 - working voltage range 200-265 volts 240 v intelligent control can control cannot control any traffic lights command three, main performance is: low power metal halide lamp itself using inductance ballast, the inductance ballast has high power consumption, high work very high starting current and starting current. 400 w metal halide at startup, for example, about 15 amperes of current, it has a great influence on the service life of electrical appliances, and often damage the air switch facilities. Consume a large amount of electrical energy at the same time, the ballast itself, cause huge electricity burden to users, and accelerated aging time. Light-emitting diodes (leds) adopts constant current drive, low power consumption, high power factor, to avoid the above problems. Color rendering index which is an important measure of light visual quality. High color rendering index, you can clearly see things in the light, the color is true. On the contrary, in the light to see is not clear, the light is dim, the object's distortion is very big. Metal halide lamp 65, low color rendering index. Work under the light source is easy to lead to myopia and visual fatigue. Low content of uv ultraviolet light is a terrible, can cause serious damage to eyes and skin, and cause eye and skin cancer. Ultraviolet content of traditional light source is very high. For example, metal halide lamp uv content accounted for 34% of the total luminous flux. Long-term under the metal halide lamp close work will cause considerable damage to human body. No ultraviolet light-emitting diode. Low repeat starting ability of metal halide lamp is turned off, need to wait for a period of time of 10 minutes to start again, or you will burn out and bring inconvenience to use. S glare is a kind of light pollution, it is by the light source itself or the light source and lamps and lanterns is caused by the improper matching. Under the strong light can cause visual fatigue and visual error, this is also the main cause of myopia. Metal halide lamp caused by uneven glass bulb manufacturing of light refraction, resulting in severe glare, they are a point light source, when used with light, easy to form a focus and glare.
