What is the difference between a light guide tube and a traditional skylight?

1.The light guide is installed in a flexible position, with low installation costs and good illumination.

2.The skylight is not equipped with any light enhancement devices to help improve the lighting effect. On the north side of the sloped roof, the normal sky is not equipped with these devices, and the amount of light is greatly reduced.

3.The Light Guide Tube captures more light from all angles and reflects it down the duct to increase the amount of light in the early morning, late afternoon, and winter when the sun is on the horizon.

4.Daylight lighting systems maximize the spread of light into the indoor sky with minimal light loss during transmission, enabling excellent illumination even on cloudy or rainy days.

1. The light guide lighting system can gather a large amount of light through the lighting device, which can avoid various structures inside the building, transmit the light with high efficiency, and then through the diffuser device, make the light evenly and glare-free irradiated to the room, and the lighting effect will not change due to the change of the incident angle of the light, and the irradiation area is large, and the local light gathering phenomenon will not be produced.

2. The lighting skylight directly irradiates the light into the room, and the irradiated surface changes with the change of the incident angle of the light, and the illumination distribution is uneven, which is easy to produce glare, and it is easy to produce local light intensity too high or local too dark, which causes adverse reactions to people's vision. With the change of the angle of incidence of light, the size and position of the irradiation area change accordingly.

3. The light guide lighting system is mainly composed of three parts: the light cover, the light pipe and the diffuser, the light cover and the diffuser are made of materials with ultra-low thermal conductivity, and the inside is completely in a sealed state, which can prevent the transfer of heat very well. Keeping warm in winter and insulating in summer can reduce the cost of using air conditioning. Ordinary skylights are generally made of glass or sun panels, the thermal insulation effect is not good, cold in winter and hot in summer, and the use of heating and air conditioning is increased in both winter and summer.

4. The light guide lighting system can achieve the effect of skylight lighting through a small lighting area (one-eighth), and the light efficiency ratio is much stronger than that of the skylight.

5. The light guide lighting system is a hollow sealing system, so it has good sound insulation performance, to achieve the same sound insulation effect, the building with the light guide lighting system only needs to be 10 meters away from the main traffic road, and the distance between the building with windows and the traffic artery must reach 50 meters.

6. Due to the large and flat lighting area of the skylight or lighting belt, it is easy to accumulate debris and dust, which affects the light transmission. Moreover, the sunlight panel is easy to be yellowed by the radiation of the sun's ultraviolet rays, which also affects the light transmission. The light guide lighting system is mostly spherical or arc-shaped, and the area is smaller than that of the skylight, and the surface is specially treated, which is not easy to accumulate dust.

A small amount of dust can also be washed by wind or rain to achieve a self-cleaning effect.

7. The coefficient of thermal expansion and contraction of skylight glass or sunlight board is different from that of the main building material, and it is easy to form a gap with the main body of the building for a long time, thus affecting the rainproof. The light guide lighting system has a small opening area, which will not be affected by the thermal expansion and contraction performance of the material itself, and can be combined with various roofs through the waterproof device of the equipment to achieve a complete waterproof effect.

8. The light guide lighting system can effectively reduce harmful radiation (ultraviolet light, infrared light) through the coating on the surface of the lighting cover, which can protect our physical and mental health to the greatest extent, and is a green, healthy, energy-saving and environmentally friendly product; The dome has strong impact resistance, etc.
