A lighting device using a light pipe for transmission

Abstract

The invention provides an illuminating device utilizing a light pipe for transmission. The illuminating device comprises a light collecting unit, the light pipe, a reflecting mirror, a side fluorescent optical fiber and a substrate, wherein the light collecting unit is arranged at one end of the light pipe, the reflecting mirror is arranged at a corner in the light pipe, the other end of the light pipe is connected with the side fluorescent optical fiber, and the side fluorescent optical fiber is fixedly mounted on the substrate. The illuminating device utilizing the light pipe for transmission, provided by the invention, utilizes the light collecting unit and the light pipe to guide outdoor sunlight into a room, and enables the side fluorescent optical fiber to emit light to replace an electrical illuminating appliance, so that the problem of poor indoor illumination in the daytime is solved, and the energy consumption of indoor illumination in the day time is reduced. The illuminating device conforms to a modern life concept that people pursue high-quality life and high-quality living environment.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device transmitted by a light guide. Background technique [0002] Lighting is one of the most energy-consuming needs of humans. According to statistics, lighting energy consumption in developed countries accounts for more than 9% of total energy consumption, and lighting energy consumption in developed areas of my country accounts for 6% to 9% of total energy consumption. In the United States, for example, the cost of lighting is as high as 100 million U.S. dollars per day, accounting for about 1 / 4 of the total power generation. Second, only 25% of the electricity used for lighting is actually used for lighting, and the rest is converted into heat. [0003] As we all know, sunlight is the most typical and most powerful natural light source, and it is inexhaustible and inexhaustible. In fact, only a small amount of sunlight can be used as indoor lighting for people ...
