Semiconductor lighting is the development trend in the field of lighting in the future, which has become the consensus of all countries in the world. The development of the domestic semiconductor industry has made great progress today, and the support at the national level is also increasing. At the 7th China International Semiconductor Lighting Forum "Policy and Industry Development Summit" held recently, the National Development and Reform Commission promoted Lu Fang, deputy director of the Energy Saving Lamp Project Management Office, said: In the next few years, China's green lighting project will focus on promoting and supporting the healthy development of the semiconductor lighting industry. It is planned that by 2015, the annual output value of semiconductor lighting energy-saving industry will increase significantly year by year: functional lighting will reach 20%, LCD backlight will reach 50%, and market share of landscape decoration and other products will reach 70%.
However, on the one hand, the government's strong support, on the other hand, the popularity of led in the field of general lighting is still not high. In order to understand the reasons behind this phenomenon, the author conducted a random interview in the semiconductor lighting forum.
According to industry insiders, LEDs want to be popularized in the field of general lighting. The performance is only a prerequisite, and the cost is the real determinant. At this stage, the cost of LED lighting equipment is 5-10 times that of fluorescent lighting fixtures and HID appliances. The reason for the high cost is the price of light source per unit brightness and peripheral components. The price of white high-power LED is much higher than that of traditional lighting fixtures. Luminaire products also require peripheral components such as heat sinks, power supplies, and lenses.
According to relevant business sources, it is necessary for domestic enterprises to focus on strong performance in the early stage of semiconductor lighting development. When the industry develops to a certain stage, enterprises should shift their attention to how to reduce costs significantly under the premise of ensuring performance. Only in this way can it be accepted by the general public.
The analysis of the person in charge of a certain LED lighting company, LED products to reduce costs, there are generally several ways: First of all, to reduce the cost of materials, in the original product program to lower the supplier's material price, reduce the material grade or select alternative materials, this method is the most direct Effective, but limited in scope, and there are certain quality risks; secondly, it is to reduce the cost of technology, adopt new technology routes, change the original product plan, reduce the materials and manufacturing links, this method is considerable, but not all companies can To do, after all, technical research is a problem that has long plagued domestic companies; in addition, it can enhance production efficiency to reduce costs, which depends on advances in technology, equipment and management.
As a new industry, the semiconductor lighting industry will inevitably have various problems in the development process, and cost is one of the key factors. With the continuous improvement of the industrial chain, the continuous improvement of enterprise technology, and with the increase of government support, it is only a matter of time before the large-scale popularization of semiconductor lighting in the field of general lighting.
