Novel LED underground lamp

Abstract

The invention discloses a novel LED underground lamp. A lamp shell is in threaded connection with a lamp cover, tempered glass is installed on the lamp cover in a pressed mode through a sealing rubber cushion, the portion, located under an LED illuminating plate, of the lamp shell is provided with a controller, a sound sensor and a voltage adjusting device, the sound sensor and the voltage adjusting device are connected with the controller, the sound sensor is used for collecting the sounds near the lamp, and the voltage adjusting device is used for adjusting the voltage flowing into the LED illuminating plate; when the sounds collected by the sound sensor reach a preset decibel value, the controller controls the voltage adjusting device to adjust the voltage flowing into the LED illuminating plate to be lowered to 40-60% of full-load voltage. According to the novel LED underground lamp, the structure is simple, the electricity consumption is saved, the luminance decrease of an LED light source is slowed down, in addition, the weakened illuminating of the underground lamp is achieved, and the discomfort caused to human eyes on account of dazzle of the lamp is avoided.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a novel LED underground lamp. Background technique [0002] Buried lights are widely used in lighting decoration in squares, restaurants, private villas, gardens, conference rooms, exhibition halls, community landscaping, stage bars, shopping malls, parking sculptures, tourist attractions, etc. With the continuous development of science and technology, the application of LED underground lights has emerged. Although LED underground lights have achieved the effect of energy saving and environmental protection, whether it is installed indoor or outdoor LED underground lights, from a distance, LED underground lights Buried lights have achieved high-efficiency lighting, but when people come closer to observe, it is easy to find that the LED buried lights will produce glare, causing discomfort to the human eye, especially outdoors, if you drive past the LED buried lights with high ef...

Problems solved by technology

With the continuous development of science and technology, the application of LED underground lights has emerged. Although LED underground lights have achieved the effect of energy saving and environmental protection, whether it is installed indoor or outdoor LED underground lights, from a distance, LED underground lights Buried lights have achieved high-efficiency lighting, but when people come closer to observe, it is easy to find that the LED buried lights will produce glare, causing discomfort to the human eye, especially outdoors, if you drive past the LED buried lights with high efficiency, the glare Stimulate human eyes and easily cause traffic accidents

At the same time, LED underground lights that are brightened efficiently for a long time not only consume a lot of power, but the light decay of LED lamp beads is fast, and the light pollution is serious from the perspective of human vision.
