Sunlight conveyor for direct illumination of basement

Abstract

The invention discloses a sunlight conveyor for direct illumination of a basement, which comprises an automatic polar coordinate sunlight tracking system, wherein a plurality of condensers which are arranged on the ground are connected with the automatic polar coordinate sunlight tracking system, optical output ends of the condensers are connected with optical input ends of a light guide device, the light guide device extends into the basement, and optical output ends of the light guide device, which serve as an illuminating surface, are arranged on a ceiling of the basement. The sunlight conveyor differs from the method for directly illuminating an underground structure by lighting drums which are commonly used at present, and condensation is achieved to increase the brightness, so that the problem of low brightness is solved; and transmission illumination in the air is achieved directly in a reflecting mode, so that the cost of the system is greatly reduced when compared with that of a light-guide fiber transmission illumination system. Besides, a method for achieving uniform illumination of a large area by secondary curved surface reflection is used for further optimizing the luminous effect after condensation, and the sunlight conveyor which serves as an enhanced lighting source for the underground structure is the optimal choice with respect to the method. The sunlight conveyor is obvious in social benefits such as energy conservation and emission reduction and has great practical values.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and relates to a sunlight conveyor, in particular to a sunlight conveyor for direct lighting of a basement, which can directly use sunlight to enhance lighting of underground buildings through transmission-type spotlighting. Background technique [0002] For underground building lighting, underground buildings such as urban underground buildings are becoming more and more common in today's land protection. However, the lighting cost after putting into normal operation accounts for about 20% of the cost of use. Therefore, no matter from the perspective of energy saving and emission reduction, or in order to reduce the cost of use, it is an ideal solution to directly use sunlight for daytime lighting according to its architectural characteristics, because generally underground buildings are built in open spaces. Below, there are usually green areas on the ground, which creates condition...

Problems solved by technology

[0003] However, the concentrating sunlight conveyor in the prior art directly implements the enhanced sunlight basement lighting system. The concentrator adopts a line concentrator composed of reflective folded glass strips, which is not as convenient as the cylindrical type in design and construction, so it is adopted Point spotlight is more suitable; in addition, after concentrating, the sunlight that is enhanced to several times or even dozens of times directly enters the underground building through the light-transmitting tube to realize lighting, because the light is too strong and too concentrated to make the effect poor; so increase the corresponding astigmatism device to ensure the best effect and high efficiency of enhanced solar lighting
