Laboratory Stand “Automotive Lighting and Signal Systems”

Educational and laboratory stand for conducting laboratory and practical classes on studying the device and functioning of the lighting and light signaling system of the car. The lighting and light signaling system of the VAZ-2108 car is implemented in full compliance with the system that is installed in the car. The color marking of the wires is completely preserved in the stand. The stand provides for the possibility of conducting direct electrical measurements in the circuits of the vehicle being studied, as well as introducing malfunctions with their subsequent diagnosis using any known diagnostic equipment of the systems under study. The fault entry block allows you to enter 24 faults such as broken wires, shorting of wires to the body, shorting of wires between themselves. Faults are entered not from the stand panel, but in specialized software through a personal computer. Structurally, the stand is an aluminum case, which houses the front panel of the stand and elements of the car’s lighting and light signaling system. In the upper part of the front panel, there is a dashboard and rear lights of the car. In the lower part of the stand, there are car headlights. In the central part of the stand, on the left, there are control bodies for the lighting and signaling system:

• Left steering wheel switch
• Outdoor lighting switch
• Emergency alarm switch
• Rear fog lights switch
• Device lighting switch

In the central part of the stand on the right is the assembly block of the car. On the front panel, there are input automatic switches, measuring devices (voltmeter, ammeter), and toggle switches imitating the operation of sensors of the car alarm system. On the back panel of the stand, there is a fault input unit and an electrical diagram of the car’s lighting system is shown.

Attached to the stand are:

• A set of methodical and technical documentation intended for the teaching staff
• Software

1. Product Introduction

The teaching board of automobile lighting and instrument system is based on the actual automobile instrument, instrument sensor, and external lighting system, fully demonstrating the composition structure and working process of automobile instrument, instrument sensor, and external lighting system. The teaching board of Passat automobile lighting and instrument system is suitable for the teaching needs of schools for the theory and maintenance training of automobile lighting and instrument system.

2. Functional characteristics

1. Real and operable automobile instrument, instrument sensor and external lighting system, fully demonstrating the composition structure of automobile instrument, instrument sensor and external lighting system. Manipulating various lights and operating switches can truly demonstrate the working process of automobile instrument and external lighting system.
2. The panel of the teaching board adopts high-grade aluminum-plastic plate that is resistant to impact, pollution, fire, and moisture, and the surface is treated with primer spraying by special process. Students can intuitively compare the circuit diagram and the actual object, and understand and analyze the working principle of automobile lighting and instrument system.
3. The panel of the teaching board is equipped with detection terminals, which can directly detect the electrical signals of various circuit components of automobile instrument and external lighting system on the panel, such as resistance, voltage, current, frequency signal, etc.
4. The panel of the teaching board adopts 1.5mm cold plate stamping structure or aluminum profile, which has a beautiful appearance. The frame part adopts steel structure welding, the surface is sprayed, and it has self-locking casters. The base of the teaching board is equipped with a desktop of about 40cm, which is convenient for placing materials, light testing instruments, etc.
5. The teaching board uses ordinary 220V AC power supply, which is converted into 12V DC power supply through internal circuit transformation and rectification. No battery is required, which reduces the trouble of charging. The 12V DC power supply has anti-short circuit function.
