Description

Technical Field

[0001] The present application relates to the technical field of stair lighting, and in particular to a stair lighting system based on gravity sensing. Background Art

[0002] In order to meet the needs of stair lighting, many people now choose to use induction stair lights. The existing staircase lights are generally voice-controlled lights or light-controlled lights. The problem is that voice-controlled lights require artificial noise to light up, which is easy to disturb people, and are often caused to light up by abnormal noises in the external environment. This is extremely inconvenient for the elderly to operate and may even cause accidents. Light-controlled lights are usually on all night, resulting in a waste of electricity. Therefore, some stair lighting systems usually need to use gravity sensing control. Utility Model Content

When the pedestrian's foot leaves the pedal 2 on the step, the spring 14 supports the pedal 2 so that the pedal 2 rises to its original position. At this time, the pressure sensor on the step stops transmitting the electrical signal to the control unit, and the light strip 15 of the step stops emitting light. The operation is convenient, and the walking of pedestrians can be accurately sensed by gravity sensing to ensure effective lighting of pedestrians. In addition, the limit mechanism can limit the pedal 2 during the lifting process to ensure the stability of the pedal 2.
