Lights, just as its name implies is car in vehicles, a warning signal when turning the front or car pedestrian or vehicle role.
Automotive lights principle
A, tube using xenon lamp, SCM control circuit, about the rotation stroboscopic uninterrupted job. Second, adopt flashers: according to the different structure, can be divided into resistance wire type, capacitive and electronic 3 kinds. Including resistance wire type and can be divided into hot wire type (DianReShi) and wing chip (bounce type), and electronic and can divide hybrid (with touch the point with electronic components) and relay to fully electrical (not relay). For example, using leaping type flashers, thermal principle, with current as motivation, heat bilges cold shrink to spring of produce mutations actions to connect and disconnect contacts, realizing with flashing lights.
Automotive lights classification
According to use material points, is divided into: 1, gas car lights; 2, the LED lights cars. According to base to points, divided into: 1, P21W; 2, PY21W; 3, W21W; 4, P27W; 5, W5W; 6, H5W. By location points, is divided into: 1, former lights; 2, the lights; after Three, side lights.
According to the material classification description
Gas car lights
Gas lights, i.e. the car use, such as halogen gases. Gas car lights, mature technology, low prices, but generates radiation, inside contain mercury, the shell is made of glass, easily broken, cause environmental pollution.
The LED lights cars
High power LED lights cars
The LED lights, i.e. the car used materials are LED. The car made by LED lights, no radiation, no pollution, long service life, theoretical reach 50,000 hours, that is to say, in the vehicle without change during bulb. But, the LED lights price is more expensive car, therefore, to its popularization use formed a certain effect. In developed countries, has LED lights in the use of the car, at home, still less.
According to base the elucidation of the classification
P21W
P21W, power is 21W, bulb 26.5 mm diameter is with venture mm, also can is called BA15S or 1156. Make it light bulb can be called spherical bulb. Common use models such as swifts, Peugeot 206, etc. Can be used as lights or lights before, but after used lights after.
PY21W
PY21W, power is 21W, bulb 26.5 mm diameter is with venture is BAU15S can also be called a mm, P21W alike, shape and tentacles, just two P21W into 150 degrees and is 180 degrees. Common use models such as byd F3, Benz S department. Can be used as lights or lights before, but after used lights before.
W21W
W21W, power is 21W, bulb diameter is T20 - T25, can also be called 7440. Common use models such as jeep - Europe rand. Can be used as lights or lights before, after, multi-purpose vehicle.
P27W
P27W, power is 27W, bulb diameter is T20 - T25, can also be called 3156. Can be used as lights before or after the lights.
W5W
W5W, power is 5W, bulb 10.29 mm diameter is with 26.8 mm, lamp holder is expressed as W2.1 x 9.5 d. W5W can be called straight inserts or flat plug, make it light bulb can be called wedge bulbs. Used vehicles such as lights, common side byd F3, swifts, etc.
H5W
H5W, power is 5W, bulb diameter is 9.0 mm, presidents are 33.0 mm, lamp holder says 9s for BA. Make it light bulb can be called spherical bulb. Used as side lights.
According to the position classification description
Lights before
Lights installed in the car before, in turn, used for beside headlight, warning ahead vehicles.
Lights after
Later in the rear of the car lights, installation, for in cornering, warning rear vehicles.
Side lights
Lights, installed in the side of the car door cab 1 in the rearview mirror, or install in cornering, warning for beside vehicles.
