Daylight lamp

Abstract

The invention relates to the field of lighting equipment, in particular to a daylight lamp which is small and exquisite in structure, convenient to use, high in day lighting efficiency and long in service life of a light sensor, and can conduct and use daylight to illuminate. The daylight lamp comprises the following parts: a day lighting barrel, a condensing lens, a scattering lens, an inner shaft, an outer support, an outer shaft, a light beam, a steering control system and a lamp body, wherein the condensing lens and the scattering lens are placed in the day lighting barrel successively; the inner shaft is arranged outside the day lighting barrel and is connected to the outer support through an inner motor; the outer shaft is arranged outside the outer support and is mounted at a day lighting site through an outer motor; the light beam is further arranged in the day lighting barrel and comprises a central day lighting optical fiber and surrounding light sensing optical fibers; the other ends of the light sensing optical fibers are connected to the steering control system; the other end of the day lighting optical fiber is connected to the lamp body; and the lamp body can be turned on or turned off independently.

Description

technical field [0001] The invention relates to the field of lighting equipment, and more specifically, relates to a daylight lamp with compact structure, convenient use, high lighting efficiency, long service life of photosensitive elements, and the ability to conduct and utilize sunlight for lighting. Background technique [0002] As a new energy source, solar energy has the advantages of being inexhaustible, green and pollution-free. With the development of fiber optic technology, fiber optic lighting systems that directly use sunlight for lighting have developed rapidly. Its main applications include warehouses, underground parking lots, etc. When providing lighting, the safety problems of traditional circuit lighting are avoided. [0003] In the daylight fiber optic lighting system, the most critical technology is the real-time response to the sunlight angle. At present, in the daylight tracking scheme, there are mainly "solar motion trajectory tracking scheme" and "...

AI Technical Summary

Problems solved by technology

This method has two disadvantages: first, the photosensitive element or its guiding fiber is greatly affected by the surrounding stray light, which makes the tracking error larger; second, the photosensitive element works for a long time, so the cycle of replacement parts or maintenance is short

In order to improve the first shortcoming, there is a technical solution to add a filter plate, but it increases the complexity and cost of the device, and at the same time reduces the sensitivity
