Description
Technical Field
The utility model relates to a can carry out building intelligence solar protection devices of light guide illumination.
Background
In the prior art, building sunshade integration design, a technology is a design of integrating a building sunshade plate and a solar collector, and the technology is mainly characterized in that a photovoltaic power generation assembly is installed on a steel structure support on the outer wall of a building, so that photovoltaic power generation is carried out on one hand, and the outer sunshade of the building is carried out on the other hand. The technology is called building photovoltaic integration, and has the defect that indoor lighting is influenced while sunshade power generation is carried out by utilizing a photovoltaic power generation assembly.
In the prior art of light guide illumination, there is a light guide and photovoltaic integration technology, which is characterized in that a large-sized light-absorbing shade is arranged on a building roof, sunlight is collected through the light-absorbing shade, then a photovoltaic power generation assembly is arranged at the bottom of the light-absorbing shade, the sunlight collected by the light-absorbing shade is used for photovoltaic power generation, and the generated power is used for LED illumination and other purposes. The main defects of the technology are that the lighting cover is fixed and is influenced by the solar incident angle and the inherent light reflection of the lighting cover, so that the lighting efficiency is low, meanwhile, the photovoltaic power generation assembly is arranged below the lighting cover and is not beneficial to heat dissipation, the photovoltaic power generation efficiency is low, and the solar energy utilization rate is low.
The prior conventional technologies for building sunshade are mainly divided into three types, 1, sunshade by greening; 2. a window element sunshade treated in conjunction with the building structural element; 3. locate the fixed independent sunshading board of building outer wall. The three sun-shading measures have certain limitations and cannot effectively control indoor environment to achieve optimal comfort level, and the common defect of the three sun-shading measures is that the sun-shading effect is influenced at the same time.
Conventional light guide illumination systems are composed of three parts, a lighting cover (hemispherical or hemispherical diamond), a light pipe, and a diffuser. The disadvantages of this technique are:
1. in a conventional light guide illumination system, a light guide is generally an aluminum guide with a large size, and the installation of the light guide needs to reserve a special pipe space in a building, so that the installation requirement is high, and the limitation of the building condition is large. For the above-ground buildings, most of the existing conventional light pipe lighting systems are fixedly installed on roofs, the light pipes are large in size and heavy, the light pipe lighting systems are convenient to install for the top floors of the high-rise buildings, however, the light pipes are inconvenient to install for the lower floors of the high-rise buildings, the light pipes are too long, a large amount of natural light energy is lost, too little natural light reaches the space of the low-rise buildings, the lighting effect is poor, and the lighting effect is greatly influenced by the height of the buildings. For the underground building space, the existing lighting system lighting cover of the conventional light pipe is arranged on the underground roof, the system is used for making large lighting holes in the underground roof structure, then the large lighting cover is embedded into the lighting holes, and the sunlight collected by the lighting cover is directly used for basement lighting. The installation of the lighting cover needs to be provided with a building structure opening in advance, is limited by the internal functional layout of a building, and some areas cannot be provided with the structure opening (such as an underground peacetime and war combined parking garage), so the application range is greatly limited by the building function. Meanwhile, the lighting cover is arranged on the reserved hole, and a measure for strengthening the waterproof of the building needs to be considered, so that the building ceiling at the mounting position of the lighting cover is ensured to be watertight. When no building waterproof measure or waterproof protection measure fails, the installation position of the lighting cover is easy to leak water and seep water, and the use of the internal functions of the building is affected.
2. The lighting cover of the conventional technology is fixed, the lighting efficiency is greatly influenced by the solar incident angle, the period without too bright illumination is needed for rest at noon, the solar direct light is directly emitted, the lighting cover efficiency is maximum, the light guide illumination is maximum, the solar incident angle is smaller in the morning and afternoon periods, the lighting cover efficiency is lower, the light guide illumination is reduced, and therefore the light guide illumination is unstable.
3. The light-collecting cover of the conventional technology is large in size and is made of colorless transparent glass, when sunlight is collected, a part of light rays can be reflected back by the glass, and the light ray loss is large; the light refracted into the lighting cover through the colorless glass is full-spectrum light, namely light with wave bands of ultraviolet rays, blue light, visible light, infrared rays and the like. Ultraviolet rays and blue light are harmful to human bodies, and the infrared rays have heat effect, so that the indoor temperature is increased, and the energy consumption of the air conditioner is increased.
4. Light guide lighting fixtures of the conventional art can only transmit natural light transmitted into the lighting fixture for illumination when the light is sufficient. In cloudy days or at night when the light is insufficient, the light guide lighting fixture cannot emit light for illumination. At this time, an electric lighting lamp is additionally arranged. The lamps required to be installed are of various types.
