1. Application of Optical Materials and Coatings
Electric Lighting Skylight achieves energy saving in the lighting process, which first depends on the clever use of optical materials and coatings. Glass is the main lighting medium, and the use of low-emissivity (Low-E) glass is a common and effective way to save energy. The surface of Low-E glass is coated with multiple layers of metal or other compound films, which can selectively reflect and transmit light. When lighting, it allows a large amount of visible light to pass through, ensuring sufficient natural light in the room, while reflecting most of the infrared rays to reduce heat transfer. For example, in summer, the infrared rays in solar radiation are reflected back, reducing the heat absorption in the room and reducing the burden of air conditioning and cooling; in winter, it can reduce the indoor heat dissipation through the glass and reduce heating energy consumption.
In addition, some skylight glasses also use photochromic coatings. This coating will automatically adjust the color depth according to the light intensity. When the sunlight is strong, the coating color becomes darker, reducing the light intensity and heat entering the room, and avoiding discomfort caused by excessive indoor temperature and excessive light. When the light becomes weaker, the coating color becomes lighter to ensure sufficient lighting.
2. Lighting Angle and Light Guiding Design
The lighting angle and light guiding design of Electric Lighting Skylight are also crucial to energy saving. Reasonable lighting angles enable sunlight to enter the room more effectively in different seasons and times. Through precise architectural design and adjustment of skylight installation angles, sunlight can penetrate deep into the room in winter, increasing the warmth of the room, while in summer, when the sun's altitude angle is large, the depth of direct sunlight into the room is reduced, reducing the need for cooling.
At the same time, the light guiding structure inside the skylight helps to optimize the lighting effect. Some skylights are equipped with reflectors or light guides inside. The reflector can reflect sunlight to the area in the room that needs lighting, improve the uniformity of lighting, and reduce the energy consumption of additional shading or light adjustment due to excessive local light. The light guide can change the propagation direction of light, guide more light deep into the room, so that areas far away from the skylight can also get sufficient natural light, reducing dependence on artificial lighting.
3. Energy-saving adjustment of intelligent control system
The intelligent control system plays a key role in the energy-saving lighting of Electric Lighting Skylight. Light sensors are an important part of the intelligent control system. They can monitor the light intensity indoors and outdoors in real time. When there is sufficient light outdoors, the intelligent control system automatically adjusts the degree of opening of the skylight according to the sensor data, ensuring the lighting needs while avoiding excessive lighting that causes excessive indoor temperature or excessive light.
In addition, the intelligent control system can also be integrated with other systems of the building, such as linkage with the lighting system. When natural lighting can meet the indoor lighting needs, artificial lighting equipment is automatically turned off or dimmed to further reduce energy consumption. In addition, the system can accurately control the lighting of the skylight according to different usage scenarios and time settings, such as daytime office hours and evening rest time, to maximize energy saving.
