HID power supply power is very low, the nominal power of the plant is only 35W, only about 60% of the original car halogen power. However, when HID is used for off-road vehicles, need to think about the problem of waterproofing, the fact that the boost to 23000 volts of the line if the breakdown signs, you can directly let the computer halt. In order to be from the booster to the lamps and lanterns of this section of the line waterproof seal, it is very important.
Off-road vehicles, especially those equipped with waders, need to pay special attention to this issue. We usually play car place, it is also difficult to ensure that the puddle or mud puddle will not let this sector of the line to mud and water. So I take a solid attitude towards the installation of HID on off-road vehicles, especially the location below the height of the tires to install HID lights, retaining my personal opinion.
When we purchase a light bulb, we will find that many of the products outside will indicate UV-Cut or similar words, because the light source in the matter, is a continuation of the spectrum, the light from the tungsten filament covers a variety of wavelengths from infrared to ultraviolet, and ultraviolet radiation will have an impact on the lamps, ultraviolet light can prompt polymer aging, thus cracking and whitening signs, so the big manufacturers of light products are used containing Special factors of quartz glass to UV absorption and filtration.
The choice of the final display color of the glass housing on the light source, the basic acceptance of two major types of technology: coating and tinted glass base.
Both tinted glass base and tinted film coating processes are filter modes, which means that light of a specific wavelength is allowed to pass through the coating or the glass housing. This mode will lose sectoral luminous flux, but the cost is lower, and it is easy to hold low-cost control of product quality in production.
And the metal coating process control is huge, in reality, is a simplified version of the camera optical lens coating products, belong to the increase in transmission film, by reducing the specific wavelength of light in the glass shell reflectivity, to achieve the final light source color selection, this film does not lose luminous flux, so the same power to obtain a brighter field of view, which shows the most significant is the silver warrior and golden eyes, the so-called brightening 30%, thanks entirely to its Metal coating process. However, the metal coating process processing costs are high, the thickness of the transmission-enhancing film to be controlled in the hope of obtaining a quarter of the wavelength of light color, so the precision of the coating process requires a high degree of precision. There are also the first products of the domestic plating, but the uneven plating in the glass shell, with the naked eye can directly distinguish the difference in color, while the transparency film itself depends on the thickness of the coating to play a penetrating effect on the different wavelengths of light, the effect is also imaginable. And good transparency film with the naked eye to examine the outside of the light bulb, like in the daylight to examine the oil film floating on the surface of the water, there will be seven colors, but when the light bulb is held up to examine the light transmission, it becomes a solid single color.
