HEADLIGHT STRUCTURES
Parabolic (patterned glass): This type of headlight, which is the ancestor of automobile headlights, is no longer used.

The light produced by the bulb is reflected forward from the parabolic reflector. The patterned windshield in front of the headlight breaks the light, ensuring uniform distribution in the desired directions (upper dark-lower bright, asymmetrical pattern).

Optical distance 15-40 mm. ranges from. As this distance decreases, the light produced expands. The larger the headlight reflector, the more light it gives.

H7 or H1 in two reflector versions, using H4 bulbs in single reflector version low and high beam light is obtained.

Free form (with transparent glass): These types of headlights, which started to be used since the late 1990s, are found in almost all of the cars produced today.

With powerful computers and special optical software, tens of thousands of different reflection points are created on the reflector independent of optical distance. Transparent windshield can be used as the distribution of light is shaped at these reflection points.

In this way, the performance was increased by 50%, allowing different headlight designs to be developed.

H7 or H1 in a version with two reflectors, usually in a version with a reflector Using H4 bulbs, dipped and high beam light is obtained.

Ellipsoidal (with lens): The use of this type of headlights is becoming more common day by day, in order to be used in different areas in parallel with the development of technology (bi-xenon headlight, rotating headlight etc.) are constantly being developed.

An elliptical reflection surface is created on the reflector with powerful computers and special optical software. The shield in front of the reflector cuts off the unwanted part of the light produced. The lens in the front collects the remaining light and reflects it forward.

In this way, smaller and more effective reflection surfaces can be created and light distribution in different patterns can be obtained. Usually 60-70 mm. lenses are used in diameter. As the diameter of the lens grows, the light pattern expands.

Generally dipped beam with high ellipsoidal projector, high beam is designed as a free from reflector. Diff and high beam is obtained by using H7 or Xenon in ellipsoidal projector and H7 or H1 bulb in free form reflector.

COLOR AND LIGHT
Color temperature what ?

Color temperature is the color of light, it has nothing to do with the amount of light. When the color temperature is increased, the share of blue in the light increases, and the share of red decreases.

Unit: Kelvin (K)

White light is divided into three basic temperature groups:
5000K and above daylight white
more blue diminished eye sensitivity 5000 K - 3300 K natural white
more whiteoptimum eye sensitivity3300K and below warm white more reddening eye sensitivity

What is the amount of light?

It is the power of light that radiates from the light source in all directions and can be evaluated with eye sensitivity.

Unit: Lumen (lm)
HEADLIGHT AND BULB TYPES

Halogen headlight: In today's cars, halogen headlights are widely used. The primary reason for its preference is that it does not require expensive components, so its cost is low.

There are also manufacturers that seldom prefer ellipsoidal projectors in halogen headlights, which often use free form reflectors.

Therefore, different types of halogen bulbs are produced.

Halogen bulb: Halogen, iodine, bromine and other gas mixtures are filled into the bulb.

Tungsten wire gives light by heating as a result of current passing over it. Meanwhile, the temperature of the wire rises up to 3000 ºC and the metal socket of the bulb rises to around 500 ºC.

Xenon headlight: Generally used as dipped beam, xenon headlights are used with lens ellipsoidal projectors to ensure the light distribution is smooth and sharp. There are also some manufacturers who use reflector-based Xenon headlights.

The projector / reflector used is designed according to the optics of the Xenon bulb.

Due to the long warm up time of the xenon bulb, the halogen headlight reflector and bulb are used in the high beam.

Bi-Xenon headlight: The difference from Xenon headlight is that it can produce high beam light from Xenon bulb.

Moving shield in front of the ellipsodial projector is moved up and down with a small motor to achieve dipped beam.

Bi-Xenon feature works only when dipped beam is on, a separate halogen headlight reflector and bulb are used to make the selector when dipped beam is off.

STRENGTHENING HEADLIGHTS

Factors: There are many factors that affect night vision.

Driver's age and eye health: As the age of the driver increases, the need for light increases to see. The eyes of a person aged 10 years need 25% more light.

Headlight quality: Modern headlights are designed and calculated by very powerful computers. Far-east or sub-industry headlights produced mostly for appearance may not reach the quality of the original headlight.

Headlight lens and reflectors status: Dust inside, blackened, dirty headlight glasses and reflectors prevent the headlight from providing good illumination. A dimmed headlight can not be corrected due to long use, you should replace it with a new one.

Headlight height level: Headlights adjusted higher or lower than normal cannot provide good lighting and also disturb oncoming drivers.

Quality and duration of use of headlight bulbs: Manufacturers recommend replacing old headlight bulbs with good quality and standard bulbs every 3 years.

Weather and environmental conditions: Rain and foggy weather conditions prevent the dipped beam of dipped beam and cause it to be reflected back to the driver. It was found that a wet road surface absorbed 85% of the light.

Which brand? It is recommended that you choose the brands of ampoules that are used by car manufacturers originally and whose quality is known.
Auto Express bulb tests H7 + 50%, H1 + 50%
H7 + 30%, H1 + 30%
Auto Bild bulb tests H4

Cheap, not manufactured according to European standards (ECE) Since the bulbs have poor geometry, they cannot provide proper illumination.

High wattage bulbs: Your car's headlight assembly is designed for 55W standard halogen bulbs. Using bulbs that draw more current can damage the electrical installation, headlight glass or reflectors.

Many auto electricians can claim that your headlights will give better light when they plug in unbranded bulbs that draw high watts (e.g. 100W) with devices like relays. These bulbs, which are generally produced in the Far East, can not emit the light properly, cluster them to the wrong points, it is illegal, because it draws too much power, its life will be short.

White-blue light bulbs: Many bulbs that are said to give white light like xenon and have blue, xenon, hid, 5000K, 6000K inscriptions are sold.

These bulbs, which are mostly produced for the tuning sector and appealing to the appearance, have a deceptive exterior appearance that looks like white with a blue paint coating applied on it.

The blue-purple effects that are seen when looking at the xenon headlamp from a distance are not due to the bulb, but to prismatic effects caused by the refraction of the light scattered from the projector in the lens. It is not possible for any standard halogen bulb to approach the performance or color of the Xenon bulb.

Since blue light has a low wavelength, it cannot be easily absorbed by objects. Our eyes are not very sensitive to light of low wavelength color. Since the amount of blue color in the light increases, these bulbs lose their lighting effect especially in rain and fog.

For the brands that are legal and manufactured in accordance with European standards, the above-mentioned disadvantages also apply.

REPLACING THE BULBS

You can change the bulbs in your headlights by using the following explanations. You can determine which type of bulb you should use from the Types of bulbs used by the headlights. For more detailed information, please refer to your vehicle's user manual.

For vehicles with xenon headlights, such operations must be carried out by an experienced auto electrician!

1. Choosing daytime hours will facilitate replacement, choose a bright environment to see the clip and other details holding the bulb in the headlight.
2. Failure to use your headlights until at least half an hour will make it easier to replace them, otherwise it may damage your hands as the bulb inside the headlight will be very hot.
3. Stop the engine and turn off your headlights before starting the replacement.
4. Open the engine cover and remove the plastic covers located behind the headlight.
5. Disconnect the electrical socket attached to the metal feet of the bulb.
6. Open the metal clip holding the bulb and remove the old bulb by its metal feet from the socket. You should not touch the glass part of the bulbs.
7. Fit the new bulb so that the body tabs fit correctly, fix the bulb by holding the electrical socket and metal clip in the same way.
8. Turn on your headlights and check if they work.
9. Plastic caps

ADJUSTING HEIGHT

Adjusting the height level of your headlights correctly will improve your night vision and prevent the oncoming drivers from being disturbed by your headlight lights. Although there is no definite result with the method below, you can correct the defective height settings of your headlights.
Adjusting the height of the dipped beam:

What you need:
- Tape measure
- Pencil and note paper
- Phillips or flat screwdriver

1. Make sure your gas tank is at least half full before starting the tuning process.
2. If possible, find a flat surface opposite a white wall.
3. Bring the nose of your car closer to the wall and draw the point that corresponds to the vertical center of the car with the pencil from top to bottom on the wall. (M line)

4. Mark the middle center point of your right and left dipped beam headlamps with a pencil on the wall (the intersection point of line B and line A)
5. Measure the height of this point from the ground in cm, note it. Let's call this value A (length of line A). A value indicates the height of your dipped beam.
6. Measure the distance of this point from the center of your car (line M) in cm, note it. Let's call this value B (the length of the B line). The B value indicates the distance of your dipped beam from the center.
7. Subtract 7 cm from value A, draw a horizontal line on the wall at the height of your figure. (Red line)

8. Draw by perpendicular to the horizontal line from the middle center points of your left and right headlamp marked on the wall.
9. Pull your car straight back about 7.5 meters (25 feet).
10. Burn your dipped headlights.
11. The light beam of the left and right headlights should center the vertical lines of the headlight that you draw on the wall, and the line of cut of the light beam should be just below the red line and parallel.
12. Now you can adjust the height with the headlight leveling knob on the console.
It is also possible to make more precise adjustments up-down or right-left by moving the screws on the back of the headlights with a screwdriver to the left and right.

Adjusting the height of the main beam: The main beam reflector is usually combined with the dipped beam. If you have adjusted the height of your dipped beam headlights, you do not need to make separate adjustments for your high beam headlights.

Adjusting the fog lamp's height level: You can apply the same method used for dipped beam to your fog lights.
