Abstract

The invention discloses a stadium light which can keep the illuminance of the stadium constant. The bottom of the board is movably connected to the upper box through the rotating shaft, and the bottom of the upper box is fixedly connected to the lower box. Both sides of the bottom of the lower box are provided with movable holes, and the top of the inner cavity of the upper box is fixed. A first servo motor is connected, and the output shaft of the first servo motor is fixedly connected with a threaded rod. The invention senses the illuminance of the stadium through the probe, and feeds back to the adjustable power supply. The adjustable power supply changes the luminous intensity of the LED light source body by controlling the magnitude of the current, thereby keeping the illuminance of the horizontal surface of the stadium unchanged, which solves the problem of the existing common LED lights. The effect is either too bright and too dazzling, or not bright enough, there will be obvious dark areas, uneven lighting, and the problem of not being able to maintain the level of illumination on the court.

Description

technical field [0001] The invention relates to the technical field of LED stadium lamps, in particular to a stadium lamp that can keep the illumination of the stadium constant. Background technique [0002] The full name of LED is a semiconductor light-emitting diode. It is made of semiconductor materials to directly convert electrical energy into light energy and electrical signals into light-emitting devices. It is characterized by low power consumption, high brightness, bright colors, anti-vibration, and long life. The advantages of long and cold light sources are the real green lighting. In the future of the 21st century, the lighting products with LED as the light source will inevitably replace the white woven lamp and become another revolution in human lighting. LED lamp beads are widely used in lighting lighting, LED Large-screen displays, traffic lights, decorations, computers, electronic toys, gifts, switches, telephones, advertising, urban brilliance projects and ...
