Different types of vehicles equipped with different types of automotive lighting, people can intuitively understand the importance of lighting, macro-up is concerned, it is the vehicle was an indispensable link in the micro sense, it is more car embodies the identity and status symbol, this issue, we focus on is that all automotive lighting, you want to help the selection and modification.
Automotive Lighting Type
Automotive lighting equipment business from the point of view, is divided into parking lights, showing the wide light beam lights, high beam, front fog lights , rear fog lamps, turn signals, warning lights, brake lights, reverse lights, license plate lights and so on. The width light is used to display the body in the night, the width and length; parking lights are turned off the ignition switch parking light switch direction after the fight, showing parking spaces; turn signal is open when the vehicle steering, intermittent flashes to prompt before and after vehicles and pedestrians to be careful about; brake light is used to inform the following vehicle, the vehicle in front to slow down or stop; fog lights can help improve driver visibility when driving in fog, and to ensure timely detection of the vehicle coming the opposite to take measures to secure the car will; close and high beam lights are lighting systems, light irradiation near the angle down and avoid direct exposure to the opposite drivers and pedestrians.
Automotive lighting described above belong to the car exterior lighting , exterior lighting generally use a white light color, orange yellow and red.
Automotive lighting also include internal lighting, the more common dome light, reading lights, luggage compartment lights, door light, stepping light, instrument lights, work lights, dashboard warning lights and so on. General cars and trucks located only a dome light, except for car interior lighting, but also the reliability and closed the door from the monitor's role in monitoring the door state, as long as there is not reliable and close all doors, dome light to shine. Power is generally 5-15 W, bus to the dome with the development trend of fluorescent lamps; reading light is installed in the front passenger seat or the top of the condenser to the driver when the passenger does not have to read the phenomenon of glare, lighting, wider than small, and some have optical axis adjusting mechanism.
Luggage compartment lamps are installed on the car or bus luggage compartment, luggage compartment cover when open, the lights automatically light up, light luggage compartment space. Door lamp is installed on the inside of car doors outside the bottom sheets, open the door, the door lights up, to notice later, cars to take necessary precautions; stepping lights are installed in medium-sized passenger car occupants on the steps inside the door, opening night passenger door, light the pedal; instrument lights mounted on the instrument panel opposite to the pointer and scale instrument panel lighting, power is 2W.
Instrumentation general and position-indicating lights lamps, license lamps in parallel. Some automotive instrument light emission intensity can be adjusted; alarm and indicator light, a common oil pressure warning light, high temperature warning light, charge indicator, turn signal, high beam indicator light, etc., warning light is usually red, yellow , usually green or blue light; work lights, vehicle maintenance, a vehicle can be moved using low voltage lighting tools, power generators or batteries from cars. Power is generally 21W, often with hooks or clamps, cigarette lighter plug is a little plug-and two-column two.
Replacement automotive lighting
Halogen headlamps
Halogen headlamps inert gas inside the bulb in a halogen element, mixed with gas. Smaller halogen bulbs, housing with high temperature, high mechanical strength of quartz glass and hard glass, filling high pressure inert gas man, is generally mixed with the halogen iodine or bromine. Temperature due to high working pressure inside the lamp bulb is much higher than the other. And use of halogen recycling principle, so the evaporation of tungsten has been effectively limited.
In the case of the same power, halogen incandescent lamp brightness is 1.5 times, while life expectancy is 2-3 times that of incandescent. Points from the shape of the halogen bulbs H1, H2, H3, H4 four, which is widely used in H4 dual filament headlight bulb, H1, H2, H3 bulb is a single filament headlight bulb used as an aid (such as fog lamps and Exploration According to the headlights.)
Xenon headlights
Full name is the xenon headlamps HID (High Intensity Discharge Lamp) gas discharge lamp, which uses complementary electronic ballast, 12V car battery voltage will be instantly elevated to above the trigger voltage of 23KV, the xenon headlamps in the formation of xenon arc discharge ionization stability and make it shine, to provide a stable vehicle headlamps lighting system. Xenon headlights now often mispronounced "hernia headlights", "xenon" xian bang (IA), and "immortal" words are homonyms, "hernia" read shan four tones (oblique tones), and "fan" and "fan" are homonyms .
Xenon lamp is a new type containing xenon headlamps, also known as high-intensity gas discharge lamps, the English referred to as HID Intensity Discharge Lamp.. Xenon lamp broke Edison's tungsten light-emitting principle of the quartz tube filled with inert gas-Xenon high-pressure xenon gas, instead of the traditional filament, the two electrodes and carbon compounds on the mercury through the ballast to the current 23,000-volt high-pressure stimulation of xenon light, the polarization between the formation of perfect white arc, the light emitted close to perfect the sun and ordinary bulbs, xenon lamp has two significant advantages: on the one hand, the xenon bulb has a more than ordinary halogen bulbs three times the light intensity, energy consumption is only two-thirds; the other hand, xenon bulbs use almost the same with the sun light color, to create a better driver visual conditions. Xenon lamps to light the broader, more intense light, greatly improving the driving safety and comfort.
Like ordinary light bulbs with halogen filament, but then there is no filament xenon lamp, xenon lamp and this is the most important difference between the traditional lamp. Xenon is the use of electrical discharge between two electrodes to produce luminous arc as arc welding light produced. High-voltage pulse added to the fully enclosed miniature quartz lamp (tube) between the metal electrode, motivating the material inside the bulb (xenon gas, a small amount of mercury vapor, metal halide) produces ionization in the arc light. This bright color temperature and sunlight are similar, but with more green and blue components, so showing blue shade. This substantial increase in the shade of blue and white road signs and signs of brightness. Xenon halogen lamp emitted flux is more than 2 times, while the efficiency of electrical energy into light than halogen lamps by 70% or more, so the Xenon lamps have relatively high energy density and light intensity, while the operating current is only half the halogen . Increase the brightness of the lights also effectively expand the car in front of the visual range, thus creating a safer driving conditions.
