Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an automatic adjustment device for transition lighting at an entrance and exit of an underground garage. Background Art

[0002] National standards require that the brightness change at the entrance of a building during the day should not exceed 15:1. This is mainly because it is difficult for the human eye to adapt to a lighting environment with a large change in a short period of time. For underground garages, due to the inconvenience of lighting, underground garages need to be artificially illuminated by installing lamps all year round. The illumination of the lanes is usually 50lx and the illumination of the parking spaces is usually 30lx. At the same time, the outdoor illumination value is less than 1lx at night and can reach up to 100,000lx at noon in summer, and up to thousands oflx in the morning and evening or in cloudy weather. The difference in illumination inside and outside the underground garage is as high as hundreds or even thousands of times, far exceeding the short-term adaptation range of the human eye.

[0003] When a car approaches the entrance of an underground garage during the day, the human eye cannot adapt to the sudden change in light, so the driver cannot see the obstacles in front of him and may even lose his sense of direction for a short time. On the contrary, when the car exits the underground garage, due to the high outdoor brightness, the external light forms a strong glare for the driver. Severe glare causes a decrease in visual visibility and directly affects visual function. Therefore, my country's national standard JGJ100-2015 "Garage Building Design Code" explicitly requires that ramp-type underground garage entrances and exits should be equipped with transition lighting.

[0004] In existing projects, the transition lighting of underground garage entrances and exits usually adopts the following three methods: the first method is to add high-power lamps at the entrances and exits of the lanes to increase the illumination at the entrances and exits to 300lx~500lx. This method can only reduce the difference in indoor and outdoor illumination to a certain extent, but the difference in indoor and outdoor illumination of underground garages can still be as high as hundreds of times. In addition, the long-term lighting of lamps also consumes a lot of electric energy, which is not conducive to energy saving. The second method is to add a section of glass canopy at the entrance and exit of the lane, and use the sunshade and light transmission of the glass canopy to weaken the intensity of natural light to a certain extent. The disadvantage of this method is that the shading effect is fixed, it does not have the ability to adjust the illumination, the applicable scope is small, and it is difficult to meet the environment with large changes in outdoor natural light illumination all day long. The third method is to set a fixed hollow grille above the entrance and exit of the lane, and use the grille to weaken the natural light. The disadvantage of this method is the same as the second method, and the control effect of all-weather transition lighting is not ideal. Utility Model Content
