[0002] When driving a subway vehicle, the subway driver will observe or operate the instruments and equipment on the driver's console, so a good lighting environment is necessary. Traditional existing driver's desk reading lights are installed on the brim of the driver's console. In order not to affect ergonomics and normal driving, the vertical height of the brim is very low, and the space between the driver's desk head-up display screen equipment is limited, resulting in the inability to adjust the lighting area after the reading light is installed. The driver's desk reading light source can only be illuminated from top to bottom, causing the display screen to reflect light, and it is impossible to observe the displayed information normally; some driver's desk lighting is achieved by using the spotlight solution on the ceiling of the cab, but the ceiling is a certain distance from the driving platform, and the brightness of the spotlight will be very high, causing the front windshield of the subway to reflect light, affecting the driver's observation of the front line, posing a great safety hazard, and can no longer meet the normal use of the driver. For this reason, we need to provide a driver's desk reading light with an adjustable angle. Utility Model Content
