In the lighting market model, it is estimated that the annual compound growth rate of the overall lighting terminal market will be about 5 in the next five years, and the long-term compound growth rate will be 3. The growth forecast of the terminal market is mainly based on expectations of construction speed, automobile output, etc. The long-term growth rate is expected to be consistent with the sustainable growth rate of GDP of 3. According to the lighting model, it is expected that the annual compound growth rate of LED lighting revenue will reach about 30 in the next six years and 24 in the next 10 years, driven by factors such as rising penetration rate, increased consumer awareness, and legislation prohibiting the sale of incandescent lamps. We also expect the compound annual growth rate of the traditional incandescent lamp market in the next 10 years to be-5. The lighting Terminal Market is subdivided into seven parts: office building and education, industry, automobile, residence, other indoor, outdoor and building. We expect the LED market to grow strongly in most areas as prices continue to fall and consumer awareness increases. The penetration rate in the residential sector is low today, but this situation will change with legislation prohibiting incandescent lamp sales and retailers pushing LED lights. On the other hand, in the outdoor field, LED lighting has already provided attractive cost performance, and its replacement cost is lower than that in other fields. Professional use the professional use of LED is more attractive from a financial point of view, because the energy and maintenance costs in this field are much higher, so the higher price of LED can be offset by the reduction of existing costs. In the current analysis of residential use, we assume that the lights are turned on for 6 hours a day. In the commercial field, the use time may be much longer. If we assume that a light bulb is turned on for 12 hours a day, the current period may be further shortened to one year. We believe that the current period is short enough, so as consumer awareness increases, the penetration rate will rise significantly. LED can greatly save energy, so LED is more attractive when the cost of electricity increases. In addition, LED provides greater flexibility in controlling color and temperature. Household LED in the residential market, for consumers, the upfront cost of use is more important than the total cost. In the past, compared with CFL bulbs, the advantages of LED bulbs were not obvious, because the original price of LED bulbs was much higher, which meant that the penetration rate of LED lighting in the residential market was still very low. But looking ahead, we expect LED to be more competitive than CFL in the next few years because its cost performance is still improving rapidly. We also believe that the upfront cost of LED bulbs (Retail Price) It may fall back quickly to match the price of CFL bulbs. Another growth driver for household LED is that interior designers/new buildings will use LED lighting more actively. In addition, information on the cost advantages of using LED bulbs will be transmitted, and consumers will begin to appreciate the design, controllability and flexibility of LED lamps. LED lights have other value-added features, such as the ability to change colors to match different atmospheres and occasions.
