Light panel used in building wall lighting and sunshade lighting

Abstract

The invention provides a light panel used in building wall lighting and sunshade lighting, which can be arranged on the outer wall of the building or substitute ordinary building outer wall, or arranged on the window top to substitute ordinary sunshade components to realize the integration of sunshade and lighting. The invention is characterized in that the light panel is transparent materials; the section shape of the light panel is in the shape of a cuniform, thus controlling the angle of the cuniform to ensure that the incident sunlight rays can be reflected for many times in the cuniform light panel, restraining the light ray path to a specified position and evenly arranging light rays, realizing the full-reflection of light rays in the light panel, and restraining the light rays at the end part of the light guide to be emitted indoors. The invention utilizes the reasonable design of the light panel, fully utilizes natural lighting to reduce the waste of electro-energy and achieves the purpose of large lighting quantity and even lighting.

Description

technical field [0001] The invention relates to a technical field for solving building indoor lighting, in particular to a light guide plate capable of refracting light into a room. Background technique [0002] In real life, the role of light is very important, and among all kinds of light sources, natural light (sunlight) is inexhaustible, and there is no pollution. In architectural engineering, uneven lighting and distribution is a common problem. Therefore, in the utilization of natural light, how to fully collect light and allow natural light to be evenly introduced into the room is an urgent problem to be solved at present. [0003] In architectural lighting design standards, the lighting illuminance suitable for study and work is generally ideal between 200-1000lux (lux), but it is often encountered that the position in front of the indoor window is exposed to too much direct sunlight (50,000-120,000 lux). , and at the same time, the inner illuminance away from the w...

Problems solved by technology

[0003] In architectural lighting design standards, the lighting illuminance suitable for study and work is generally ideal between 200-1000lux (lux), but it is often encountered that the position in front of the indoor window is exposed to too much direct sunlight (50,000-120,000 lux). , and at the same time, the inner illuminance away from the window is less than 100lux; this kind of severely uneven and excessively strong and weak light does not meet the needs of study and work, and is not good for eye hygiene and production safety.

In order to solve this situation, and at the same time make full use of natural lighting to reduce the waste of electric energy and reduce the greenhouse effect caused by it, in the prior art, there are various skylights or roofs with different heights for indoor lighting and uniform lighting. This kind of lighting is characterized by a large amount of lighting and uniform effect, but the structure is complex and the cost is high; there are also light pipes, condenser lenses or parabolic condensers used on the outer walls and window tops to transmit sunlight into the room, but the lighting effect is not good. it is good
