Comprehensive analysis of LED lighting design ideas

After the light emitting diode (LED) was invented in 1962, its initial applications were mostly concentrated on instrument display purposes, and then gradually expanded to the fields of 3C product backlight and lighting. With the gradual expansion of market application areas and scale, LED has made faster progress in various manufacturing and material technologies in recent years than in the past, and the design of LED indoor lamps is increasingly related to the future development of the industry.

1. The demand for indoor lighting and the lamps used

Humans have invented incandescent lamps for hundreds of years. They have a deep understanding of the functional requirements, lighting forms, lighting object types, and lighting scenarios of lighting fixtures, and have also designed many different lamps. Generally speaking, according to the different light sources, they can be divided into four stages: fossil fuel stage, tungsten filament lamp stage, fluorescent lamp stage, and LED lamp stage.

From the above-mentioned lamp styles and performances, it can be seen that every revolution in light sources will lead to huge changes in usage methods and habits, and add new scopes and methods of use.

2. Different angles of design

So how can we make LED lighting design reach its due height, so that the public can not only accept the price, but also believe that LED lighting products can provide a more pleasant life? First of all, some principles in lighting will not change much and still have great reference value.

Human lighting needs generally include four aspects: site lighting, object lighting, situational lighting, and indication and guidance lighting. Depending on the object being illuminated, it can be divided into plane light type, line light type, projection light type, and spotlight type. In addition, sometimes people need light to directly illuminate objects or illuminated surfaces, and the illumination and contrast of the illuminated objects are higher, which is called direct illumination. Sometimes light needs to be irradiated to a surface first, and then reflected to the object or surface to be illuminated, which is called indirect lighting. This type of light is usually softer and has a wider diffusion range. Designers need to design different products according to different lighting needs.

Sometimes light needs to be irradiated to a surface first, and then reflected to the object or surface to be illuminated, which is called indirect lighting. This type of light is usually softer and has a wider diffusion range. 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 entry:

1. Try free structure and appearance design

As the heat dissipation problem of LEDs is becoming less severe, the design of power circuits is becoming more and more simple and effective. The restrictions on structure and volume are also gradually fading. Such conditions allow the appearance design of LED lamps to be richer and freer, and the places where they can be used are wider. LED lamps can already enter many places where other traditional light source lamps cannot enter, providing light needs that these places could not meet before.

After understanding the design flexibility of LED, whether it is using subtractive design to reduce costs and increase price competitiveness, or using gorgeous additive design to increase appearance appeal and stimulate visual purchasing desire, both are good ways to convince buyers to accept LED.

2. Provide more flexible control options

LED's polychromaticity and quick response make its control performance far superior to other light sources. Therefore, we can limit the gap between the lighting control requirements and the performance of traditional light sources, and use LED to design lamps that other light sources cannot achieve, but can meet the public's desire for control performance. For example, smart lamps with variable color temperature, dimmable light, and automatic response according to the situation.

In addition, for those who like to play with various high-tech products, LED lamps that can be freely controlled and set are provided. For those who are not so obsessed with high-tech, lamps that can be easily controlled with one finger can also be designed. People who need to use light to create different atmospheres and adjust their emotions can also achieve the desired effect through well-designed LED lamps. Special effects professional lamps that previously required various accessories and complex control circuits can now be reduced and converted into general household and commercial lamps. These dazzling functions that originally belonged to the professional field can convince consumer decision makers that the product has higher value when they choose whether to buy it.

3. Built-in and combination

LED lamps have a simple structure, a low load on the power supply line, and the characteristics of light directionality, making it easier and more suitable for LED lamps to be built into other equipment or clustered into large devices than lamps with other light sources.

New built-in possibilities can make the device or equipment more convenient to use or have lighting performance that has never been seen before. LED backlit display screens and LED lighting for small refrigerators and cabinets are good examples. The cluster method uses LED to create a new light environment and expression. Without significantly changing the circuit or reducing the original space, you can create a magical effect by simply adding LED lamps.

Thinking about LED product development from the perspective of built-in and cluster can effectively avoid fierce competition and find business opportunities in new areas.

4. Concealing evil and promoting good

LED light sources are different from other light sources. When applied to traditional light source lamps, many disadvantages will occur, such as glare, poor heat dissipation, and unsightly light patterns. Therefore, when designing and applying traditional lamps, we should pay attention to using methods to avoid these disadvantages; if conditions permit, we should even make a completely new lamp design based on the advantages of LED and the basic lighting needs mentioned above.

If we can grasp the characteristics, advantages and disadvantages of LEDs, and add the correct design concept, we can make LED products more attractive than traditional lamps in terms of appearance, light type and usage emotions.

It should also be noted that, due to the size of LED lamps, the high temperature generated by the huge power is often concentrated in a small area. If the design does not have the design to protect the human body from burns like traditional high-temperature lamps, the chance of accidental injury will increase greatly. In addition, a large amount of light is squeezed into a smaller light spot than traditional light sources, so the visual damage caused by the light may be no less than that of laser. Therefore, there are still many things to pay attention to in the design of LED lamps.

At present, the LED lighting industry is obsessed with pursuing powerful brightness and believes that a certain technology must be the mainstream. It often ignores that lighting fixtures should pursue good light and light that people can really use. Professional and difficult data and technical descriptions cannot attract most people to accept the value of LED lamps. Objectively thinking and analyzing the needs of users, and then finding a balance between cost and performance based on the advantages and disadvantages of LED technology, is the way to accelerate the entry of LED lamps, whose prices have not yet entered the popular stage, into the market.
