parking lot

In many public places, such as halls, corridors, stairs, underground parking lots, etc., the characteristics of the lighting requirements are: long-term or even 24-hour all-weather artificial light source lighting must be provided; on the premise of meeting the illumination standards, people should provide lighting for them. Comfort requirements are lower than general general lighting. That is to say, what people need in the above places is a kind of moderate lighting, which can be expressed as “the light is on when people come, it turns dark when people go, automatic sleep, and lighting on demand”. Then, in such a place, according to this characteristic, the state of the lighting lamps can be divided into “rated power” state, “sleep power” state and other states, so as to provide satisfactory lighting for the crowd according to the time and local conditions.
Under the same lighting effect, the LED lamp saves more than 60% of electricity than traditional lighting, and has a long life. It is a green light source; intelligent devices are used to control the opening time of the lamps to achieve “on-demand lighting”, with a rated power of 12W~16W The LED light maintains the basic brightness when there is no one without a car, and the power is only 2W. When a person or a car approaches the light for a certain distance (usually about 5 meters), the LED light works at full load. In this way, the total power saving rate can reach more than 80%.
