Headlights
Two block headlights are installed on VAZ-2105 and VAZ-2104 cars (right and left), combining headlights, direction indicators and marker lights. Block headlights can be installed both domestically produced and produced in Czechoslovakia. They have the same dimensions and characteristics, but differ somewhat in design. The block headlights manufactured by Czechoslovakia are described below.
The design of the headlamps provides an asymmetric dipped beam that meets the requirements of UNECE regulations (United Nations Economic Commission for Europe). Each headlight is attached to the front of the body with four screws, which are wrapped in special plastic holders that are put on the edges of the headlight socket.
The low and high beams of the headlights are switched on by the switch 52 located on the steering column when the external lighting switch 50 is on. In addition, by pulling the long lever of the switch 52 towards you, you can get a short-term inclusion of the main beam of the headlights both when the external lighting switch is on and off. This is ensured by the fact that the voltage to the light signaling contacts of switch 52 is supplied directly from the plug "1XT" ignition switch 51, bypassing the outdoor lighting switch 50. In order not to damage the contacts of the switch 52, the headlights are switched on through additional relays 47 and 48 of type 112.3747 located in the mounting block 46.
The block headlight has a black plastic housing 14, to which a glass diffuser 1 is glued to the front with special glue. At the back, the housing is closed with a removable plastic casing 11. Thus, the internal cavity of the block headlight is isolated from dust and moisture. A reflector 15 with a headlight lamp 2 and a side light lamp 4 is installed in the housing 14. The wires from lamps 2 and 4 are connected to the plug-in block installed on the rear side of the headlamp housing. On the outer side of the block headlight there is a parabolic socket into which a cartridge with a lamp 8 of the side direction indicator is inserted. This socket is covered with an orange plastic diffuser 7.
Reflector 15 headlights - steel rectangular. Its reflective surface has the shape of a paraboloid of large diameter, bounded above and below by horizontal planes. The paraboloid concentrates the reflected light rays into a beam, directing it along its axis if the lamp filament is at the focus of the paraboloid.
Due to the increased horizontal diameter, the rectangular reflector provides large angles of dispersion of the light flux in the horizontal direction. Therefore, in the low beam, the right side of the road is better illuminated and the luminous flux in the direction of the eyes of drivers of oncoming vehicles is reduced, which increases traffic safety. To create a mirror surface, the reflective surface of the reflector is coated with varnish and then with a thin layer of aluminum. Such a coating reflects up to 90% of the light falling on it.
Diffuser 1 is made of colorless glass with a high degree of transparency. Its outer surface is smooth, and on the inner surface there is a system of prisms and lenses that turn parts of the light beam in a horizontal direction and concentrate the light flux at the most critical points of the road.
From the back, a lamp 32 is inserted into the reflector. The lamp is halogen, i.e. in her flask are iodine vapor. Halogen lamps have increased luminous efficiency and almost 2 times longer service life than conventional lamps. In addition, the luminous efficacy of halogen lamps does not decrease over time, since they do not have tungsten deposits on the inner walls of the lamp bulb and it does not darken. Since the lamp heats up to high temperatures, care must be taken to ensure that the outer surfaces of the lamp bulb are always clean. Especially it is necessary to avoid fatty traces from fingers. To do this, it is recommended to wear gloves when replacing the lamp and degrease the lamp glass with alcohol, otherwise the lamp bulb will quickly darken and the lamp will fail.
The process that occurs in a halogen lamp is as follows. Iodine vapor comes into contact with tungsten deposited on the walls of the lamp, and tungsten iodide is formed. This compound is unstable at high temperatures and, getting into the hot filament zone, decomposes into iodine and tungsten, which is deposited on the filament, and iodine moves to the walls of the flask. Thus, when the lamp is switched on, there is a constant transfer of tungsten from the walls to the filament. Therefore, the thread thins more slowly, and the walls of the flask remain clean.
Lamp 2 has two tungsten filaments: one (55 W) for low beam and other (60 W) for far. The high beam filament is at the focus of the reflector, and therefore the high beam beams are concentrated into a narrow beam, directed almost parallel to the road and well illuminating it at the maximum distance from the car. The dipped beam thread is brought forward from the focus of the reflector and is closed from below by a special metal screen. This is done to limit the upward propagation of light. If you direct a beam of low beam at the wall, then the spot of light will have the shape of an ellipse with a cut off upper half. The upper boundary of the illuminated area in the left part of the spot will pass exactly along the horizontal axis of the ellipse, and in the right part along the line emanating upward from the center of the ellipse at an angle of 15°to its horizontal axis. This shape of the beam of light provides good illumination of the road in front of the car (especially her right side and curb) and reduces the possibility of dazzling oncoming drivers.
A screen 3 is installed in the reflector in front of the lamp. It delays the direct light coming from the lamp filaments and provides a clearer boundary for the dipped beam. On the lamp flange there are protrusions that fit into the corresponding grooves of the reflector. Therefore, the lamp is installed in the reflector in a strictly defined position.
The direction of the headlight beam can be changed in the horizontal direction with screw 12, and in the vertical direction with screw 10. When screw 12 is rotated, bracket 13 moves forward or backward the left edge of the reflector, and it rotates relative to stop 6. When screw 10 is rotated, the reflector rotates relative to stop 6 and bracket 13 (those. relative to the horizontal axis). Spring 5 constantly pulls the lower right edge of the reflector back.
There is a slot 9 on the headlight housing for attaching the tip of the headlight hydrocorrector, which can be installed on some cars. The hydraulic corrector allows you to move the headlight beams in the vertical direction from the driver's seat. Such an adjustment is desirable when, with a change in the load of the car, its front end rises or falls, and, consequently, the direction of the headlight beams also changes.
Side direction indicators
Side direction indicators 19.3726 are attached to the front fenders of the car with two elastic holders 18, cast in one piece with the body. A polyvinyl chloride seal is installed under the pointer. Case 14 of the pointer is plastic. A plastic orange diffuser 1 is also welded to the body by ultrasonic welding. A holder of 19 plugs with a lamp socket is inserted into the body from the back of the pointer. A lamp 17 of type A12-4 is installed in the pointer.
Plafond. For interior lighting on VAZ-2105 and VAZ-2104 cars, a ceiling type 15.3714 is installed. The cover is attached to the roof of the car with two self-tapping screws. An AC12-5 lamp is installed in the ceiling.
The plafond has a plastic housing 14 and a transparent plastic diffuser, on which a switch 24 and a plug 20 with a contact for attaching the lamp are installed. Voltage is applied to plug 20. Plug 23 is connected directly to "weight", and plug 25 with ground through the switches in the door pillars. When the doors are opened, these switches close plug 25 to "mass", and the lamp lights up. When the doors are closed, the lamp can be turned on with the light switch.
License plate lights. The license plate lights, type 12.3747, are installed in the rear part of the trunk lid and are attached to it with two screws. They simultaneously illuminate the trunk when its lid is raised.
The lantern has a plastic body 14 and diffuser 1, which is attached to the body with a spring ledge on the body. The housing has two holder-plug 26 for installing the lamp and connecting the wires.
Rear lights
Rear lights are used to indicate the dimensions of the car at night, to indicate the turn, signaling braking and for signaling when the car is moving in reverse. The rear lights are divided into right and left. The left lamp is a mirror image of the right one. The lights are attached to the outer rear panel of the car with four screws. The same screws are used to attach the diffuser to the lamp housing.
The body 14 of the lamp is made of metallized plastic and is divided by partitions into four chambers. On the outside of the car, the lamp has two cameras. In the lower chamber there is a lamp A12-21-3 of the direction indicator, and in the upper chamber lamps 27 and 28 are installed. Lamp 28 of type A12-4 is designed for side light, and lamp A12-21-3 is for fog light. In the middle lower part of the lantern there is a reversing light camera with an A12-21-3 lamp.
Lens 1 plastic tri-color: red in the zone of the brake signal and side light cameras, orange in the zone of the direction indicator camera and colorless in the zone of the reversing light camera. In the middle upper part, a reflector 30 is welded to the diffuser by ultrasonic welding - a light-signal type device that reflects the light falling on it.
Engine compartment lamp
Underhood lamp type PD-526 serves to illuminate the engine compartment. The lamp is bolted to the air intake box located in front of the wind window. In the socket of the housing there is an A12-5 lamp, to replace which it is necessary to lightly press the button 33.
The lamp has a one-piece plastic housing 14, on the flange of which a plastic screen 39 is put on. The voltage is supplied to the plug 35. A spring contact is put on the bolt 34, the head of which is filled in the housing, connecting the central contact of the lamp with "weight" car. Button 33 is hollow, plastic. Inside the button there is a return spring, the lower part of which rests on pin 37 pressed into the housing. A contact washer 36 is installed on the bottom of the button, closing the plug 35 with the lamp base.
Glove box light. Lamp type LV-211 is installed in the upper left part of the glove box and fastened with a screw to the instrument panel. The lamp has a fastening bracket 42, to which the button guide 33 is welded. A housing 14 is riveted to the end of the plastic button 33, into which a cartridge 19 with a miniature light bulb AMN 12-3 is inserted. To replace it, it is necessary to remove the cartridge with the bulb from the housing 14. The voltage to the bulb is supplied through the plug 35, and its base through the cartridge 19, the housing 14 and the guide 41 closes on "mass" wire, the tip of which is clamped by the lamp fastening screw. The closed lid of the glove box, pressing the button, presses the case 14 from the guide 41, breaks the connection chain with "weight" and the lamp goes out.
