From Carriages to Connected Cockpits: The Evolution of Automotive Lighting- Part 1

Internal Illumination: Lighting the Way for Passengers and Drivers

The internal lamps in a bus play a crucial role in creating a pleasant and functional environment. They provide essential illumination for passengers navigating the aisles, reading a book, or simply relaxing during their commute. These strategically placed lights also enhance driver visibility during low-light conditions and nighttime operations, ensuring the safety of everyone on board.

● Interior Lighting Systems

Overhead Interior Lamp: A lighting fixture positioned above the driver's head to illuminate the dashboard and cabin interior. It is designed for stationary operation with momentary activation permitted during vehicle motion.

Exit/Entry Lamps: Illumination fixtures installed on running boards to activate automatically upon door opening. For vehicles without closable doors, these lamps must remain illuminated during nighttime operations.

Locker Lamps: Internal lighting within storage compartments or lockers makes it easier for?passengers to access their belongings, especially in dim conditions.

Electrical Distribution Panel Lamp: A lighting fixture within the electrical distribution panel that illuminates the panel interior upon cover opening for inspection and maintenance.

● Driver Interface Lighting

Instrument Panel Lighting: Lamps illuminating the dashboard and control panels help the driver monitor the bus’s performance and controls, such as speed, fuel levels, and other indicators, ensuring safe operation.

Control Unit Lamps: These are small indicator lights on control switches, signaling the status of various systems like air conditioning, door controls, or lighting settings.

● Passenger Compartment Lighting

Passenger Area Lamps: Illumination fixtures designed to provide ambient lighting within the passenger compartment, facilitating object identification and reading.

● Destination panel lighting

Destination panel lighting refers to the illumination of the display board on a bus that indicates the route number and final destination. This lighting is crucial for ensuring clear visibility of the information to passengers, especially in low-light conditions. Typically, the destination panel is located at the front of the bus. This is the most visible position for passengers?waiting at bus stops to easily identify the correct bus. Some buses have destination panels on the side for passengers waiting at bus stops or for those already inside the bus.

Hence, the bus has a comprehensive internal lighting configuration.
