Halogen Bulb The main function of the car lights is to give the driver at night to illuminate the front view, so as to enhance traffic safety, there is another role is to remind the front of the vehicle, warning vehicle location (which is more and more vehicles to add day The main purpose), so the lights for traffic safety is very important, and now the aftermarket also introduced a variety of modified bulbs to provide owners to choose.
We recommend the selection of a brand with a certain reputation for the priority, such as Philips, OSRAM are all good choice, because the modified bulbs are basically the use of lengthened tungsten ring and fill the way the high-pressure halogen gas to enhance the amount of light, Manufacturers made out of the bulb in the material is more particular about, so as to ensure that the working life of the lamp will not be substantially reduced, so that the night driving has a brighter, farther lighting effect. Modified bulbs can be divided into yellow type, bright type, high color temperature and so on several.
Yellow type also has a lot of people call it gold eyes,Halogen Bulb its color temperature is generally low, only 2600K so it will be out of the light will be yellow. The surface of the bulb is plated with a layer of yellow film, so that it is in the fog or rain when driving a better penetration, to ensure that drivers can clearly see the road.
Highlighted bulb glass is no coating, color temperature is about 2900 ~ 3100K between the filling of high-pressure halogen gas and lengthened tungsten wire coil way to enhance the amount of light, and still maintain the original 55W power consumption, as to increase the amount of light Began to volume pricing,Halogen Bulb from 30% to 130% of brightening, so that owners can buy their own needs, often at night driving can choose a higher brightness of the modified bulb to get farther lighting distance.
High color temperature type in the bulb glass coated with light blue coating, in this way the original yellow light into yellow and white light, or even close to white,Halogen Bulb such modified bulb color temperature between about 3800K ~ 4300K, and xenon lamp Color temperature is quite close, mainly to the halogen bulb will not appear dim, it seems more spiritual, and this range of color temperature during the trial car can also smooth clearance.
Of course, the market also has a lot of marked color temperature up to 4500K, 5000K or even 6000K modified bulbs, in general, this is the bulb glass coated with darker blue coating, the amount of light emitted in fact blocked a lot, it will look Very white, but it is not bright phenomenon, and the passing rate of the car is certainly not high, so do not in pursuit of dazzling visual effects but at the expense of upgrading the intention of the modified bulb Oh!
Halogen bulb and other incandescent lamp is the biggest difference is that the halogen lamp glass shell filled with some halogen element gas (usually iodine or bromine), its working principle: when the filament fever, the tungsten atoms are evaporated to the As the glass tube wall moves,Halogen Bulb the tungsten vapor is cooled to about 800 ° C and is combined with the halogen atom to form tungsten halide (tungsten iodide or tungsten bromide) when approaching the glass tube wall. The tungsten halide continues to move toward the center of the glass tube and returns to the oxidized filament. Since the tungsten halide is a very unstable compound,Halogen Bulb it is re-decomposed into halogen vapor and tungsten after heat, On the deposition down, make up the part that has been evaporated. Through this regeneration cycle, the service life of the filament is not only greatly extended (almost four times that of incandescent), but also because the filament can work at higher temperatures, resulting in higher brightness, higher color temperature Higher luminous efficiency.
