Hidden light source is a kind of healthy lighting that has been developed recently and widely used in the future. The hidden light source illumination distinguishes the traditional point light source, and the surface light is illuminated. The uniform brightness of the whole space is the most obvious feature, which is different from the effect of the spatial point light source shape or the light or dark effect;
From the structural point of view, the hidden light source uses a homogeneous light-transmitting material as the light-emitting surface to hide the light source behind it and achieve the effect of the light-emitting surface;
From the composition point of view, hidden light source illumination is divided into: light source, light surface material, structure and light source control.
Light source: The most commonly used ones are fluorescent tubes and LED strips.
Luminous surface materials : more common: acrylic, light-transmissive film, Class A fire curtain and glass.
Structure: Mainly based on metal structure.
Light source control: ordinary switch, voice control, light control, intelligent control - can control brightness and color temperature, color and so on.
The biggest advantage of hidden light source is that the brightness is even, the light is soft, which improves the comfort of human habitat and is more healthy.
In this paper, we focus on the latest technology materials - light-transmissive film and light curtain as the hidden light source design of the light-emitting surface material.
Look at the picture before introducing it:
The above figures show the spatial representation of the transparent film material, which can be longitudinal, transverse and planar.
At the same time, the color of the film is very rich, and the color of the design can also be adjusted from the color of the light.
The main component of the light-transmissive film is PVC, the thickness is 0.18mm, fire-retardant and fire-resistant, anti-aging. From the history of product development, there are French barrisol and German dukiee brand, which plays a very important role in the development of the industry.
Drawings, textures, etc. can be printed on the film, as shown in the figure:
Design structure:
Of course, not only this kind of design structure, complex structures need to be deepened by professional companies, and they are not listed one by one.
After the famous CCTV fire, Shanghai Jiaozhou Road fire and certain commercial buildings and other fires, began to reflect on the safety performance of building materials, the materials used at the top must reach Class A fire protection, so after these accidents, the requirements for the top building materials are greatly improved. The Class A fire curtain is also born for safety.
As shown in the figure, the application of light curtain hidden light source:
