For security purposes, the vehicle must have different lights to show its presence and to help the driver to visualize the movement of the vehicle. Bright driving lights must not dazzle the drivers of oncoming vehicles and hence some arrangement is incorporated to dip the main beam. The lighting circuit includes the battery, vehicle frame, all the lights, and various switches that control their use. It is known as a single-wire system since it uses the vehicle frame for the return. The complete lighting circuit of a vehicle can be broken down into individual circuits, each having one or more lights and switches. To identify lighting-circuit components, their functions and maintenance procedures, De Lorenzo has designed demonstrators, with real components, allowing the final user to study and to test the parameters of the vehicle lighting system subassemblies (direction indicators, hazard lights, fog lights, wiper equipment, brake and reverse lights, etc.) and to learn the structure of lighting system studying its components and performing various measurements and other diagnostic procedures. They are recommended for professional institutes, vocational schools and technical colleges.
LEARNING EXPERIENCE The trainer allows studying and testing the parameters of the vehicle lighting system subassemblies. It allows learning the marks and graphic symbols of the electrical installation elements according and testing the resistance, the voltage and the power in the vehicle installation system. GENERAL CHARACTERISTICS • Dim. mm approx (HxLxW) : 1700x1000x500 • Weight approx. kg 150 • Input power supply: AC 220V±10% 50/60 Hz • Operating voltages: 2x12V -15A • Working temperature: -40℃ ~ +50℃. MAIN CHARACTERISTICS This demonstration trainer includes the following systems: • Direction indicators, hazard lights • Passing lights, driving lights and parking lights • Fog lights • Brake and reversing lights • Headlight lift regulator • Vehicle interior lighting • Wiper equipment • Vehicle horn sound • Window wash system The experimental stand allows also to demonstrate the reaction of a system to the most frequently observed types of failures, such as interruptions in output circuits or in output circuits, short circuit to positive or ground.
LEARNING EXPERIENCE Training board-simulator is a great educational tool that allows students to learn the structure of lighting system, study its components, and perform various measurements, tests and other diagnostic procedures. GENERAL CHARACTERISTICS • Dim. mm approx (HxLxW) : 1700x1000x500 • Weight approx. kg 150 • Power supply: AC 220V±10% 50/60 Hz • Working temperature: -40℃ ~ +50℃. MAIN CHARACTERISTICS Lighting system trainer installed in a mobile aluminium frame and it is based on OEM components of VW/AUDI cars. The main characteristics and functions of the trainer are: • Open contacts for measuring of system's components and circuits. • Electric wiring diagram with built-in banana plug jumpers for measurements and connecting or disconnecting the components. • Diagnosis through OBD 16 – pin diagnostic connector diagnostic socket (Dashboard only) (OBD not supplied) • Adjustable level with the motors of front headlights.
