Metal halide lamps VS Halogen light bulbs

The metal halide lamp is an AC power source, which generates an arc discharge light emitting light in a mixed vapor of mercury and rare metal. Its main characteristics and advantages: high luminous efficiency up to 100 lumens / watt fluorescent color color temperature close to 6000 high color color rendering index higher than 90 heat starting capability adjustable light currently there are three forms of goods in the sales: double ended with "GS" technology, with relatively small electrode gap between the electrodes, have higher arc brightness to improve lighting efficiency. "The ultra quiet HMI single ended non external foam housing has a special pedestal design, although there is a very small diameter also allows hot start. Especially suitable for compact lamp system. The single end of the outer bulb has the outer bulb of the lamp is easy to carry and equipped with electronic ballast can avoid noise. The outer door improves the dimming characteristics and allow the lamp can ignite position. And then turn the voltage to about 85V, a steady supply of xenon light bulb.

The day of the sun's light color temperature 5000K, HID is close to the white light of the sun. In addition, HID has also avoided the general halogen lamp is easy to oxidation and the longer the time of illumination, the more dark the light, the lighting distance is wide and long. Xenon lamp safety than halogen lamp xenon lamps and halogen lamps, the main difference is, the former by gas ionization luminescence, the latter by tungsten filament heating luminescence. Specifically, the advantages of xenon lamp is reflected in the following five aspects.

A), brightness, using the same wattage HID, brightness is about 2~3 times that of incandescent light. Although xenon lamp luminous arc and halogen lamp filament length of similar diameter, but the luminous efficiency and brightness are increased nearly 3 times.

B), energy saving, compared with incandescent light, can save nearly half of electricity. The advantages of saving half of the electric energy is obvious.

C), long life, due to the use of the filament, without the traditional lamp is easy to brittle fracture, the life of HID also increased by nearly 10 times, can be used for up to 2000~3000 hours.

D), security, in fact, this is the greatest charm of HID. A lot of use of the HID's owners, the installation of the HID light line of sight, the safety of driving at night is greatly improved. This is mainly because the HID light brings multiple beams and intensity will be more effective than simple, near light set, can greatly improve the lighting in front of the car, to illuminate the road signs, the importance of the safety of the road is beyond doubt.

E), should be acute, due to xenon lamp and halogen lamp light emitting principle is different, when the battery power supply problems, it will be extended a few seconds to go out, so that the owners have a certain time to deal with emergencies. How to correctly identify true and false xenon lamp fake xenon lamp mostly through improving voltage of halogen lamps, produce high brightness to consumer fraud, then how to know eye lamp, to identify genuine and fake xenon lamp? Using fake xenon lamp is: first, the high temperature, because of high temperature cracking lamp, have fused lamp. Second, the effect is poor, and the HID comparison, bright enough, color difference. Moreover, the power consumption is large, to use the enhanced line, after the installation will appear idle instability and other phenomena. So, this needs in the purchase process open bright eyes, the price is low, because power consumption is big, idle high, fuel consumption, some to replace imported spark plug, in order to ensure power supply system. So, this is the need to open the eyes in the purchase process, choose the quality of the xenon lamp, so that it can achieve superior results. When the discharge is stable, the partial pressure of mercury vapor is less than that of 102Pa. For the high pressure mercury lamp high-pressure mercury lamp is a kind of electric light source with high efficiency, long service life. It consists of two parts and fluorescent bulb tube. Discharge tube thin and short, is only the size of a man's finger, is installed inside the high-pressure mercury vapor discharge tube outside Yimian spherical fluorescent bulb. Electrical discharge produces visible and ultraviolet strong ultraviolet irradiation, fluorescence in the bubble shell, a large number of visible light. Red does not contain a high pressure mercury lamp light irradiation, it objects blue, it is only suitable for square, city street lighting.
