Second, the lamp transformation of small power and lighting circuits design problem is relatively complex. A lot of car headlights are still using incandescent power 45/55W power is relatively small; headlights of some cars is directly on the separation of gross vehicle circuit harness the power transmission, the headlights get voltage than the total circuit The lower voltage to 1-2 volts. Ordinary incandescent lamp metal tungsten light in a vacuum environment to obtain the brightness, but the metal tungsten is energized under the vacuum environment, generating light while also generating the tungsten vapor, resulting in the gradual decline in brightness, lighting more darker.
If you want to improve the brightness of the headlights, do not directly replace the high-power light bulbs, as is likely to cause the circuit to overheat and even burn. But should be in the replacement of high power lamp at the same time, to change the circuit. Now the popular modified on the market in a better operability: the original car headlights interface of two is to plug an exterior circuit, through the vehicle's battery power transmission directly to the headlights, can guarantee a sufficient voltage; after the change of the original car headlight circuit used as a switching circuit, and in this way can the vehicle's headlights replaced 90/100W halogen lamp, brightness greatly improve the safety of driving at night is also greatly improved.
Often at dusk and dawn driving of the driver of the vehicle can be considered two small bright lights installed in the front of the vehicle, but also nice and safe.
Modified method on the headlights of the vehicle there is a better, but the price is expensive. That is, xenon headlights. The brightness of the lamp can be achieved the effect of sunlight. The use of such lamps, the visual fatigue of the driver driving the vehicle in the night greatly reduced, the security is also improved.
