Intelligent lighting: new opportunities under the transformation of the lighting industry

Lighting industry pattern changes

China's lighting industry started from the early 1980s. After 30 years of rapid, stable and sustained development, it has grown from a small industry with an initial production value of less than 10 billion yuan to a total annual production value of 350 billion yuan in 2011. industry. In the meantime, even with the cyclical adjustment of the Chinese economy, the Chinese lighting industry has basically maintained a double-digit growth momentum.

Marketization has spawned the development of private enterprises. Lighting enterprises, especially the lighting industry, have the characteristics of low investment, quick effect, and strong product personalization. In the mid-1980s, when China changed from a planned economy to a market economy, it attracted a large amount of private capital into the lighting industry in a short period of time. The number of companies has increased rapidly. In this process, the state-owned lighting enterprises that led the lighting industry gradually withdrew. In the late 1990s, China's lighting industry was mainly dominated by private enterprises, and state-owned enterprises were few left.

Increased market competition has led to corporate integration. The rapid increase in the number of enterprises has intensified competition in the market. In order to ensure the competitiveness of the market, enterprises have increased investment, expanded the scale of enterprises, integrated upstream and downstream resources, and strived to minimize production costs. For example, the light source enterprises use mechanization to expand production capacity, and the lighting companies integrate the ballast industry. During this period, many light source companies and ballast manufacturers closed, stopped, and transferred.

Changes in end market demand have changed the market position of light source companies and lighting companies. The improvement of living standards has changed consumers' demand for lighting products. Consumers' understanding of brands has changed, which has led to changes in the market position of lighting companies, and further promoted the integration of upstream and downstream resources of the lighting industry. Many light source companies have developed downstream and started to produce lamps. The lighting companies have developed upwards and are involved in light source production. In the early 1980s, the debate about "chicken and eggs" in the field of lighting ended in vain.

Smart lighting or smart home energy saving preferred

The so-called intelligent lighting control products output an optimal lighting power to the lamps under the condition of ensuring the normal operation of the lamps. This can reduce the illumination glare caused by over-pressure, make the light emitted by the light softer, the illumination distribution is more uniform, and can save a lot of energy. The intelligent lighting control system can save 20%~40%.

At present, urban managers gradually realize the technological advantages of intelligent lighting products and begin to promote them in the society. At the Olympic Technology Outlook Forum, smart lighting was put on the agenda. The relevant departments of Shanghai decided to install an intelligent control system for the street lights on the main landscape roads in the center of Shanghai during the summer peak hours. Although the government promotes smart lighting products, the intelligent lighting control technology is complex, and there are few companies that master this technology, such as Lutron in the United States and Australia's Bonzi, Thorne, ABB and other powerful companies. There are only a few companies at the level.

From the current development of intelligent lighting control technology, various companies apply modern technologies such as PC, IC, IT, etc. to the switch technology, adding new functions such as wireless remote control and stepless adjustment of brightness to the lamps, which is convenient for users. From the perspective of the composition of the lighting control system, there are mainly bus type, power line carrier type, and wireless network type. From the perspective of technology development, wireless network technology has unique advantages. In recent years, it has developed rapidly in the IT field and has become a new hot spot in the IT industry and the semiconductor industry.

The wireless network lighting control system is a home intelligent network control system that uses radio to communicate. The control signals sent by each system control unit are transmitted in the form of radio waves. After receiving the propagation information, each system control unit performs corresponding actions according to the provisions of the system communication protocol to implement intelligent network control.

Like the power line carrier solution, the wireless lighting control system does not have a dedicated network cable, and installation or expansion is very simple. This solution can also be powered by a battery, without the need to connect the power cord, which is very flexible and convenient, and also reduces the cost of the user.

Industry experts pointed out that the intelligent lighting control system connects the dimming module, switching power, scene control panel, sensor and programmer, programming socket, pc monitoring machine and other independent control modules on the computer data line to form an independent lighting control system. Intelligent management and automatic control of the lighting system can be realized, which is convenient for creating a comfortable lighting environment and is beneficial to people's health. It will become a new trend in the development of lighting technology in the future.

Intelligent lighting expands LED smart home market

Some experts predict that intelligentization is an important way for the lighting industry to further move towards green and sustainable development. Intelligent lighting is expected to become the main force in the future smart home market. At present, intelligent lighting has changed from a single remote control switch to today's intelligent induction lighting, intelligent scene lighting, intelligent remote control lighting, and the effect achieved from single dimming to today's lighting soft start speed, Cool and warm lighting, high and low voltage dimming, LED full color spectrum dimming, etc.

The combination of intelligent and energy-saving lighting technology has built a technology platform for LED applications, embodying the concepts of green and sustainable lighting such as energy saving, consumption reduction, long life and people-oriented. In addition to energy saving, consumption reduction and environmental protection, LED lighting is also plastic, not only as a lighting tool, but also as a work of art or a multi-purpose object. The development of LED technology has stimulated the imagination of lighting manufacturers, which has created more creative products that subvert the mind and won a broader market.

LED lighting has a small size, its structure is simple, there are no additional parts and casings such as starters, ballasts or ultra-high voltage transformers, no volume limitation and complicated structure; it produces color by the semiconductor PN junction itself, three The basic color plus digital technology can evolve any color; the compact LED light source can adapt to the decorative lighting requirements of various geometric sizes and different space sizes. For example, shapes such as points, lines, faces, balls, and even any artistic sculpture. Therefore, LED smart lighting is used in the home field, and can be perfectly combined with home creativity to bring an imaginative home life.
