1. Functional principle:
The prerequisite of lighting design must meet the functional requirements, and the lighting design that cannot meet the basic functional requirements is of no evaluation value. Therefore, in the early stage of lighting design, different lighting methods and performance techniques should be planned according to different Spaces, different occasions and different objects to ensure proper illumination and brightness.
For example, the conference hall can use vertical lighting, requiring uniform brightness distribution to avoid glare, generally appropriate to choose comprehensive lighting fixtures; Shop window and commodity display, in order to attract customers, generally use strong light to highlight the image of the product, its brightness is 3 to 5 times higher than the general lighting, in order to strengthen the three-dimensional sense of the product, texture and advertising effect, often use directional lighting and color light to improve the artistic appeal of the product.
2. Aesthetic principle:
Lighting is an important means to decorate and beautify the environment and create an artistic atmosphere. To decorate the space, increase the level of space, render the environment atmosphere, you can use decorative lighting. The use of decorative lamps is very important. In the environmental design of modern home buildings, theater buildings, commercial buildings and entertainment buildings, lighting has become a part of the whole. Lamps not only play a role in ensuring lighting, but also pay attention to its shape, material, color, proportion, scale, lamps have become an indispensable decoration of indoor space. Through the rhythmic control of light and shade, recirculation, intonation, strength and so on, the lighting designer gives full play to the brilliance and color of the light. Through the control of transmission, reflection, refraction and other means, it creates a warm and soft, quiet and elegant, pleasant and romantic, brilliant, magnificent, joyous, rhythmic, mysterious, confusing and other artistic atmosphere. For people's living environment to add colorful interest.
3. Economic principles:
Lighting is not necessarily more good, to win strong, the key is scientific and reasonable. The lighting design is to meet the needs of people's visual physiology and aesthetic psychology, so that the indoor space can maximize the practical value and appreciation value, and achieve the unity of the use function and aesthetic function. Flashy lighting not only can not be icing on the cake, but it is icing on the cake, while causing power consumption, energy waste and economic losses, and even cause light environmental pollution and harm the health of the body. Lighting related data standards, due to the use and resolution of different clarity requirements, the selection of standards are also different.
4. Security principles:
Lamps are the carrier of lighting design implementation, requiring absolute safety and reliability. Because the lighting comes from the power supply, strict safety measures must be taken to prevent electric shock, prevent circuit breakers and so on to avoid accidents.
