How to classify xenon bulbs?

Abstract: Xenon lamp is a kind of light bulb filled with xenon and other inert gases, which can be called metal halide lamp or HID xenon lamp. The luminous principle of xenon lamp is that various chemical gases are filled into the ultraviolet-cut anti-ultraviolet crystal glass tube, and then xenon in the quartz tube is excited by high-voltage amplitude, so that electrons are released to form a light source. Xenon lamps can be classified in many ways, so let's look at them by edge-cutting. 1. What is the luminous principle of xenon bulbs?

The luminous principle of xenon lamp is that a variety of chemical gases, most of which are xenon and iodine, are filled into the tubular anti-UV-cut anti-UV crystal timely glass tube, and then the DC voltage of 12 volts on the vehicle is instantly boosted to 23,000 volts by the ballast, and xenon electrons in the quartz tube are excited by the high voltage amplitude to be free, thus generating a light source between the two electrodes. This is called gas discharge. The white super-strong arc light produced by xenon can increase the color temperature of light, similar to sunlight during the day. The current required by HID is only 3.5A, its brightness is three times that of traditional halogen bulbs, and its service life is 65,438+00 times that of traditional halogen bulbs.

Second, how to classify xenon bulbs?

(A) According to the model

1, 900 series

Series 900 includes 9004(HB 1), 9005(HB3), 9006(HB4), 9007(HB5) and so on.

2.h series

H series includes H 1, H3, H4, H6, H7, H8, H9, H 10, H 16, H 13, etc.

3, D series

Series d includes D 1S, D 1C, D 1R, D2R, D 1C, D2C, D3C, D4C and so on. Also known as the lens series.

(2) according to the light bulb lighting mode

1, long arc xenon lamp

Long arc xenon lamp, also known as tube xenon lamp, can be made into single-ended and double-ended extraction. The radiation spectrum of long-arc xenon lamp is close to sunlight, which is suitable for large-area illumination and can also be used as light source for film photography, color photography, plate making and copying. At the same time, it can also be used as simulated sunlight and artificial aging light source in cotton fabric color inspection, drug and plastic aging test, plant cultivation and photochemical reaction. In addition, high-power long-arc xenon lamp can also be used as continuous laser light source.

2, short arc xenon lamp

Short arc xenon lamp, also known as spherical xenon lamp, is a point light source with extremely high brightness. Its color temperature is around 6000K, and its color is close to sunlight. It is one of the light sources with the best color rendering in gas discharge lamps at present, and is suitable for film projection, exposure, train head and simulated sunlight.

3, pulse xenon lamp

Pulsed xenon lamp is a xenon lamp that uses stored electric energy or chemical energy to produce high-intensity flash in a very short time. It has the characteristics of strong load capacity, high pumping efficiency, good laser beam quality and long service life. The peak flash energy of pulsed xenon lamps can range from a few joules for medical and lighting photography to millions of joules for ballistic aerial observation and laser light source. In addition to the lamp tube, the pulsed xenon lamp also has various shapes such as U-shape, spiral shape and disc shape.
