After the invention of light-emitting diodes (LEDs) in 1962, most of the initial applications were concentrated on instrument display applications, and then gradually extended to 3C product backlights and lighting. With the increasing application field and scale of the market, in recent years, LED has made more rapid progress in various manufacturing and material technologies than in the past. The design of LED indoor lamps is more and more related to the future development of the industry. . First, the needs of indoor lighting and the use of lamps Humans have invented incandescent lamps for hundreds of years. They have a deep understanding of the functional requirements of lighting, lighting forms, types of lighting objects, and lighting scenes, as well as many different lamps. Generally speaking, according to the different illuminants, it can be divided into four stages: petrochemical fuel stage, tungsten lamp stage, fluorescent lamp stage and LED lamp stage. From the above-mentioned luminaire styles and performances, it can be seen that each revolution of the light source will lead to huge changes in the way of use, habits, and new range and method of use. Second, the different dimensions of the design So how should we make the LED lighting design reach its height, so that in addition to the price, the public can believe that LED lighting products can provide a more enjoyable life? First of all, some of the principles of lighting will not have Big changes still have great reference value. Human lighting needs generally include four aspects: site lighting, object lighting, context lighting, indicating and guiding lighting, and are divided into flat light type, line light type, light projection type and concentrated type according to the different objects. In addition, sometimes people need light to directly illuminate the object or the illuminated surface, and the illumination and contrast of the object are high. This is called direct irradiation. Sometimes it is necessary to illuminate a surface first and then reflect it to an object or surface that needs to be illuminated. This is called indirect illumination. This type of light is usually softer and the range of diffusion is wider. Designers need to design different products according to different lighting needs. In addition to considering different lighting needs, some design ideas can also be used to facilitate cutting: 1. Try free structure and appearance design As the LED heat dissipation problem tends to weaken, the design of the power supply circuit becomes more and more simple and effective. The limitations of structure and volume are also gradually diminishing. Such conditions make the LED luminaires more versatile in design and can be used in a wider range of locations. LED luminaires have access to many other places where traditional light source luminaires are inaccessible, providing light requirements that were previously unattainable in these locations. After mastering the design flexibility of LEDs, whether it is the use of subtractive design to reduce costs and increase the price competitiveness; or use the gorgeous addition design to add attractiveness and stimulate visual purchase, they are persuaded to buy A good way to accept LEDs. 2, provide more flexible control options The pleochroism of LEDs and the fast response characteristics make their control performance much better than other light sources. Therefore, we can limit the gap between lighting control requirements and the performance of traditional light sources. LEDs can not be used to design other light sources, but they can meet the needs of the public to have control performance. For example, it can change color temperature, dimming, and intelligent lighting that responds automatically according to the situation. In addition, for those who like to play a variety of high-tech products, provide LED lighting that can be freely controlled and set. For those who are not so obsessed with high technology, you can also design a fixture that can be easily handled with one finger. People who need to use light to create different moods and adjust their moods can also achieve the desired results through well-designed LED lamps. Special effects professional lamps that used to require various accessories and complex control circuits can now be reduced to general household and commercial lamps. These glare functions, which were originally in the professional field, can convince his products to have higher value when consumer decision makers choose whether to buy or not.
