Suitable Environment vs. LED Lighting Design
LIGHTING DESIGN AND INSTALLATION, LIGHT SOURCE LUX DISTRIBUTION, ARCHITECTURAL LIGHTING DESIGN
In the quantitative design of lighting, there are too many factors and indicators considering, and which one should be considered first? What should be a reasonable design steps? How can designers create a comfortable light environment? Just like teaching students in accordance with their aptitude; treating the disease requires the right medicine, it is the same for lighting design. In different situations, the demands for light parameters are different, so what we have to do is to analyze the specific problem.
As a lighting designer, before the actual “fencing”, the first thing to do is to know ourselves and the others, just as the teacher should master the book knowledge before the class, the doctor must understand the efficacy of various drugs before writing down the prescription. Therefore, for lighting design, the first step is the collection and classification of large-scale environmental data, including the light source ontology capabilities and the requirements for different application scenarios.
The light source ontology capabilities include optical frequency, spectrum and light distribution. For optical frequency, we mainly study high-frequency driving; for spectrum, we need to understand brightness, chromaticity and radiant power; and in light distribution, we divide near field distribution and far field distribution, etc.
With this information, we need to give a reasonable choice of light source for specific application scenarios. Just as in commercial lighting, different application scenarios, different requirements for color temperature and illumination density, can refer to the following figure.
In the home environment, different places such as living room, bedroom, kitchen, restaurant, etc., are not the same in terms of the illumination angle of the light source. Please refer to here.
After the collection and classification of environmental big data are completed, it is necessary to comprehensively analyze the positive and negative effects of different light sources in distinctive application scenarios. What kinds of light source are suitable for the situation, the lighting designers must be fully confident in knowing what to do.
1. Professional color reproduction.
2. The color temperature light source required by the situation.
3. Non-distortion of color on the surface of the object.
4. Frequency variation of health requirements.
Lighting design is especially important for humans. A good light environment can make our lives healthier and better!
