According to the model of the lamp head, the HID model and the halogen bulb have a one-to-one correspondence. That is, what type of original halogen bulb is, and when the HID is modified, the same model is also required. At present, HID is divided into the lamp head model: H series: H1, H3, H4, H6, H7, H8, H9, H10, H11, H13, etc.; 90 series: 9004 (HB1), 9005 (HB3), 9006 (HB4), 9007 (HB5), etc.; D series: D1S, D1C, D1R, D2R, D1C, D2C, D3C, D4C, etc.; others: 880, 881 are more commonly used in automotive HID H1, H4, H7, 9005, 9006, 9007 and other models. The H4, H13, 9004, and 9007 models have two tungsten filaments in their original halogen bulbs. One is the far light and the other is the near light. Because the xenon light can't be made in a tube Light and high beam, so there are four series, such as: H (also known as a single light, but also only the far light or near light). Under high temperature and high temperature, it is easy to blow and the life time is only 250 hours on average; HID lamp uses gas discharge to emit light, there is no tungsten wire, and it is not easy to damage. H4-3, H13-3, 9004-3, 9007-3, and H4-H/L, H13-H/L, 9004-H/L, and 9007-H/L types of xenon lamps are all Xenon lamps with far and near light. ; where H/L is the high/low representation (High/Low).
Types of Xenon lamps
The types of xenon lamps are divided by bulb type according to the bulb type of xenon lamp. Generally, they can be divided into three series, 900 series, H series and D series. . The 900 series has 9004\9005\9006\9007. The H series has H1\H3\H7\H8\H11\H4. The D series has D1\D2\D4. These models correspond to the general headlight bulb model of a car. There is also a modification of the car headlights, is called with a lens with angel eyes, which is a modified xenon lamp. The lens is better for the concentration of the headlights, but the modified headlight seal is not very good. The angel's eye is a decorative effect that is not practical. In Europe, the use of xenon bulbs must be accompanied by a qualified lens and headlight cleaning device that meets the standards. This is to prevent improper use of xenon headlamps as a safety hazard in driving. There are no domestic laws and regulations, but it is still advisable to adapt at least the corresponding lens when refitting the xenon headlamps and carry out corresponding debugging.
