what is hybrid solar lighting

Mixed lighting is composed of general lighting and local lighting. A new technology that combines natural light and electrothermal light in a single floodlight is a technology that counters traditional fluorescent design knowledge. Hybrid lighting technology is more energy-efficient than traditional electrothermal lighting systems, providing designers with unprecedented design flexibility, and can be used in places where sunlight is used inside buildings.

For a long time, domestic countries have not paid enough attention to the mixed lighting of natural light and artificial light. Most office buildings still use traditional lighting methods. At the same time, natural light can provide a lighting environment that cannot be achieved by artificial light sources. In fact, the use of natural light for lighting does not save energy, but reduces the power consumption of artificial light after using natural light. Therefore, natural light should be used for indoor lighting as much as possible, and at the same time, a good indoor lighting environment should be satisfied.

Although it is currently possible to obtain sufficient daylighting for office buildings through technical means, the nature of natural light determines its variability. Under different weather conditions, it can be divided into various sunny and full sky models. And the indoor illuminance will also become uneven, so it is necessary to use artificial light sources to compensate lighting.

At this stage, daylighting of natural light in office buildings is mostly achieved by adjusting the amount of light entering through blinds. In the control of blinds, sensors are often used to collect relevant data, and the corresponding control strategies are obtained after analysis and processing. At present, the control strategies are mainly neural networks or fuzzy control. Among them, the choice of control method determines the control effect of the entire system. As early as the middle of the last century, architectural lighting and lighting scientist Hopkinson proposed a theory called indoor constant auxiliary artificial lighting, which can reasonably combine natural light and artificial light to form a good indoor lighting environment. ^[1]

For a long time, lighting

Today, with electric lighting dominating, the use of natural light lighting has become an issue of increasing concern in modern commercial buildings. Natural light lighting can not only reduce energy consumption, but also improve the quality of indoor lighting environments. Nowadays, traditional glass and specific doorway design have become the usual methods of introducing daylight into buildings, but there are problems in introducing regional limitations. With the development and use of new and efficient optical materials, light guide technology has emerged at the historic moment, and to some extent, it has made up for the problem of area limitation. The tube-type natural light introduction system is currently used as a light guide product, and is used as a lighting device for transmitting sunlight. Therefore, in order to achieve high-efficiency applications of daylighting and electric lighting in the same space, the development and research of hybrid lighting systems has become The inevitable trend. ^[2]

During the day, natural light enters the office through the window. The value of the illuminance at the location near the window is large, and the value of the illuminance at the location far from the window is small. In order to meet the requirements of indoor illuminance uniformity, the illuminance should be balanced. Therefore, the artificial light illumination should be reduced near the window, and the artificial light illumination should be increased at a distance from the window. ^[1]

Also during the day, the brightness near the window will be very high, and the indoor staff will feel the surrounding of the window is very dark. In addition, the shadow of staff and facilities will appear indoor, which will also affect the indoor light environment. In order to avoid this situation, it is necessary to make the indoor brightness ratio reach a certain balance, that is, "brightness balanced lighting". In this case, when the brightness near the window decreases, artificial lighting should be reduced accordingly to maintain the balance of brightness. In fact, the brightness of the window is determined by the brightness of the sky, and the weather conditions are changeable. Therefore, it is difficult to use this method to achieve indoor intelligent lighting control. ^[1]

Hybrid lighting system is designed to distribute natural light and electric lighting to the interior of the building at the same time to meet the needs of indoor contrast. In short, a hybrid lighting system uses a concentrator to track the sun, collect daylight, and transmit the daylight to an indoor luminaire via an optical fiber or a highly reflective pipe. The luminaire is equipped with a controller capable of maximizing the use of natural light, thereby realizing a mixed lighting process in which natural light and electric lighting are combined and distributed. At present, the hybrid lighting technology is mainly based on the tube-type natural light introduction system. Currently, the hybrid lighting systems on the market are still in the following three forms: hybrid solar lighting (HSL), fiber-optic solar lighting system (Parans), and sun umbrella lighting System (SCIS).

This is an intelligent control type power saver based on the electromagnetic superposition coupling technology, which is widely used in various three-phase power places. Break through the traditional electromagnetic power-saving technology, and take the lead in adopting advanced magnetic superposition coupling technology. Optimize the power supply system so that the power consumption system such as lighting is always in the best working state, and the power saving effect is significant. The main circuit adopts special energy-saving reactors, no thyristor components, no harmonic pollution to the power grid, resistance to surge voltage shock, and strong resistance to instantaneous large load impact: the main circuit has no contacts and no ignition occurs. Reliable quality and significant power saving effect.
