Analysis: LED indoor lighting design thinking

After the light emitting diodes (LEDs) were invented in 1962, the initial applications were mostly focused on the use of the instrument display, and then gradually extended to 3C products such as backlighting and lighting. With the gradual increase of the market application area and scale, in recent years, LED has made rapid progress in various manufacturing and material technologies. The design of LED indoor lamps is increasingly related to the future development of the industry. .

First, the needs of indoor lighting and the use of lamps

The invention of incandescent lamps by humans, which has been in existence for hundreds of years, has an in-depth understanding of the functional requirements, lighting forms, types of lighting objects, and lighting scenes of lighting fixtures. At the same time, many different lighting fixtures have been designed. On the whole, according to the different light emitters, it can be divided into four stages: petrochemical fuel phase, tungsten filament lighting phase, fluorescent lighting phase, and LED lighting phase.

From the luminaire styles and performance mentioned above, it can be seen that each revolution of the light source will cause a drastic change in usage patterns and habits, and increase the scope and methods of new use.

Second, the design of different dimensions

So how should we make LED lighting fixture design reach its proper height, so that in addition to accepting the price, the public can believe that LED lighting products can provide a more pleasant life? First of all, there is no major change in the principle of lighting. It still has great reference value.

The lighting needs of human beings generally include four aspects: site lighting, object lighting, situational lighting, indicating and guiding lighting, and according to the different objects to be photographed, they are divided into planar light type, line light type, cast light type and concentrating type. In addition, sometimes people will need light directly to the object or the lighting surface. The illuminance and contrast of the object will be higher. This is called direct illumination. Sometimes it will be necessary to first irradiate light to a surface and then reflect it to the object or surface that needs to be illuminated. This is called indirect lighting. This kind of light is usually softer and spreads more widely. 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 to free the structure and shape design

As the LED heat dissipation problem tends to weaken, the design of the power supply circuit becomes more and more concise and effective. The limits of structure and volume are gradually diminishing. Such conditions allow the design of LED lamps to be more plentiful and free, and they can be used in a wider space. LED luminaires have access to places where many other conventional light fixtures cannot enter, providing the light requirements previously unavailable to these locations.

After mastering the design flexibility of LED, whether it is to use subtraction design to reduce costs and increase price competitiveness; or to use gorgeous design to increase the appearance of attraction, stimulate the visual desire to buy, are persuading to buy Home is a good way to accept LEDs.

2, to provide more flexible control options

The pleochroism and rapid response of LEDs make their 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 design LEDs with other light sources that cannot be achieved, but we can satisfy the lighting fixtures that the public hopes to have control performance. For example, it can change the temperature, dimmable, according to the situation of the automatic reaction of intelligent lamps.

In addition, for those who like to play with various high-tech products, they provide LED lamps that can be freely controlled and set. For those who are not so obsessed with high technology, it is also possible to design lamps that can be easily handled with one finger. People who need to use light to create different situations and adjust emotions can also achieve the desired effect through well-designed LED lamps. In the past, special effects lamps with various accessories and complicated control circuits were needed. Now, all channels can be converted into general household and commercial lamps. These dazzling functions, which are originally in the professional field, can persuade his products to have higher value when the consumer decision maker chooses whether or not to purchase.

3, built-in and combination

The structure of the LED luminaire is simple, the load on the power supply line is relatively low, and the light directing characteristic makes the LED luminaire design easier and more suitable for being built into other instruments and devices than the luminaires of other light sources, or The own cluster combines large devices.

New built-in possibilities can make the device or device more convenient to use or have previously had no lighting performance. LED backlight display and small refrigerator, cabinet LED lighting is a good example. The cluster approach uses LEDs to create new light environments and expressions. There is no need to drastically change the line or reduce the original space, but by adding LED lamps, you can create fantastic results.

Thinking about the development of LED products in the direction of built-in and clustering can effectively avoid fierce competition and find business opportunities in new areas.

4. Hidden evil

There are differences between LED light sources and other light sources. When applied to a conventional light source, there are many disadvantages, such as glare, poor heat dissipation, and poor light quality. Therefore, in the design of the use of traditional forms of lighting, we must pay attention to the use of methods to avoid these shortcomings; if the conditions permit, even according to the advantages of LED, as well as the aforementioned basic lighting needs, to make a new lamp design.

If you can grasp the characteristics and advantages and disadvantages of LED, plus the correct design concept, LED products can show more attractive than traditional lamps in appearance, light type and use mood.

In addition, it should be noted that although the size of the LED lamp, the high temperature generated by the huge power is often concentrated in a small area, if the design does not have the same as the traditional high-temperature lamps, with the design to protect the body from scalding, The chance of accidental injury will increase greatly. In addition, a large amount of light is squeezed onto a light spot that is smaller than a conventional light source, so that the visual damage caused by the light may be no less than the laser light. Therefore, there are still many issues that need attention in the design of LED lamps.

At present, the LED lighting industry blindly pursues a strong brightness, paranoid belief that a certain technology must be the mainstream, and often ignore the light that lighting fixtures should be pursued is to feel good light, can make people really use. Professional and difficult data and technical instructions do not attract most people to accept the value of LED lamps. Analyze and analyze the user's demand objectively, and then find out the balance between cost and performance according to the advantages and disadvantages of LED technology, and it is the method that can make the LED lamps and lanterns that have not yet entered the popularization stage enter the market faster.
