Why dim lights

Or how to achieve the most efficient lighting?

Let's talk about why over time, lights begin to dim light, perhaps enough on a deserted highway, but totally ineffective in the lively, especially if large counter-flow.

Sometimes sin generator and a voltage regulator, it is the truth: failure of these devices visible on the "movement" of the luminous flux, as it obeys the number of engine revolutions. It is clear that no matter the work of the generator and regulator napryadeniya not only affects the efficiency of lamps - the first to suffer the battery, or do not get a full charge, or on the contrary - it receives in excess of that "boiling" the electrolyte. Lights in this case played a role of an indicator, although excessive voltage greatly reduces the life of lamps. Constant as the dull radiation occurs for other reasons: a heavily soiled or covered with corrosion reflector, or covered with a dark touch the inner surface of the bulb.

If the durability of the reflector depends on many factors, which we will talk Yeshe, even quite serviceable lamp "gaining" a dark patina of what some 30-50 thousand kilometers. Its efficiency in this case by 20 percent below the new one.

Reflector "live" longer. In modern cars and glass reflector lamps are, so to say, an indivisible whole, that in the first, of course, turn provides the most optimal light beam, and the second - the tightness. That lack of tightness contributed to the penetration of dust into the headlamps, which is then burnt on the reflector and reduces its vsetootdachu. The same thing happened with moisture and actively kondensirvoavsheysya on the reflector, which is corrosive.

Five years ago, we tried to fight corrosion in some incredible way, flooding the spotlight on the red brake fluid. Fashion this rather harmful than useful undertaking has passed, but there was the other extreme - the plexiglass "points" on the glass. Besides the fact that such protection reduces the light output, "smearing" the direction of the rays, it is caused by strong heating and burning of the reflector. Which in this case is the use of a secure otkamney glass reflector if the suffering - is not clear, moreover, as has been said, glass and reflector are now indivisible whole? By the way, so there is no reason to buy the "lens" alone: good light from a lamp will never achieve.

Finally, regarding adjustments. Even perfectly lights fitted with halogen lamps, may be useless on the road if they are handled anyhow. Not everyone, and not always an opportunity to make an adjustment on the bench. So very good results give an old, well-tested methods of the "home" of adjustment. The machine is mounted on a flat area, measured 30 meters and put a mark on, say, a brick. One of the headlamps, included dazzle than a halt, and the second - turn the adjusting screws so that the border lighting vertically to bring to put a brick. The same is done and the other headlamp. The main beam is controlled in the horizontal direction, but without the bricks: here it is important to ensure that the beams from both lamps are not bifurcated and converged in the middle.
