Description

The laboratory stand should be designed to carry out a set of practical work on studying the distribution system and light intensity in the headlights of modern cars with various light sources, as well as developing initial skills in diagnosing, maintaining and repairing a car as part of the course “Design, repair and operation of motor vehicles »

General requirements
The stand should consist of two modules — a measuring module and a headlight module.
The headlight module is a frame made of aluminum profile with a tabletop made of gray laminated chipboard with a front panel made of anodized aluminum with a full-color image applied to it using metallography technology.
The front panel contains two headlights with different light sources — a halogen lamp and a xenon one; the power supply terminals, headlight terminals, controls, ignition unit, and electrical measuring instruments for voltage and current are also located on the front panel.
The measuring module is an optical-mechanical device for checking and adjusting headlights, allows you to check the directivity pattern of the light beam and measure the intensity of the headlights.
The device is equipped with a digital lux meter and a laser pointer. Fixed stand with sliding nylon pads.
The device allows you to:
— Measuring the angles of inclination of the cut-off boundary of the low beam beam to the plane of the working platform on which the vehicle is installed;
— Measuring the angular deviation from the zero position in the horizontal direction of the intersection of the left horizontal and right inclined sections of the cut-off boundary of the light beam of the low beam headlights;
— Measuring luminous intensity and checking the technical condition of vehicle headlights.
Design features:
— Mobile design on wheels;
— High-performance plexiglass Fresnel lens;
— Fixed mounting stand;
— Fixed measuring panel;
— Camera adjustment height to the center of the headlight up to 1500 mm;
