From the actual use situation, LED indoor lighting is roughly divided into industrial, commercial and home applications. Industrial indoor lighting is a market where LEDs are cut early and demand is large. The demand for products is more focused on safety, energy saving and long life. For example, industrial and mining lamps generally take high-quality, energy-saving routes and save costs. Commercial lighting focuses on scene effects and user experience, and sometimes introduces special lamps with different angles of color temperature and color rendering for various application environments; while home lighting tends to pay more attention to cost performance, the current characteristic of this field is that it is used in home applications. Mainly downlights, bulbs, etc. have entered the era of low cost. Quality reliability needs to be improved Recently, the proportion of LEDs in the field of general lighting has increased rapidly. It has opened up a broader world for the application of LED indoor lighting in the commercial field. This market is generally mostly for engineering procurement, and the demand for products is large. Therefore, it has become a key market that every manufacturer is striving for now. On the other hand, the general civil lighting market has also been fully opened, and its development speed can not be underestimated. More and more manufacturers have introduced relatively mature LED lighting products, and some products have broken through the traditional lighting in terms of functions and design. category. In 2014, LED indoor lighting faced three major tests. However, while the indoor lighting developed rapidly, the application market still had a lot of knowledge about the quality of LED lamps. LED indoor lamps have many advantages, such as energy saving, long life, safety and reliability, etc., Wu Hongfeng, sales director of Jiangsu International Sales Department Co., Ltd., but in many practical cases, because the end user's perception of LED is not comprehensive, In order to attract users' attention and rapidly increase market share, some merchants have used poor products and technologies, such as: for the brightness, abandoned the life; in order to save energy, abandoned the security, so that some terminal market feedback information is: LED lights have Good, but most are easy to break and the price is not cheap. In response to the negative impact of this short-term interest behavior, he further pointed out that the lighting market is undergoing a new round of changes, including the friction between the traditional lamps and LED lamps, once the advantages of LEDs Being artificially manufactured into shortcomings will make market promotion more difficult, especially in the initial stage of the LED application market being opened. Therefore, enterprises in the industry are urgently required to consciously abide by the technical and quality standards and jointly build a healthy industry development path. Taking the current thermal management problem that has a great influence on the quality of LED indoor bulbs as an example, although LED lighting can significantly save energy, the overall life of the bulb is said to be 30,000 to 50,000 hours; in fact, often because of LED Many components in the drive circuit, especially electrolytic capacitors, age with increasing temperature, causing excess heat in the retrofitted luminaire to significantly reduce the life of the solid-state lighting bulb, which also allows consumers to expect a high quality LED luminaire. discount. Hubie Notohamiprodjo, Director of Solid State Lighting Product Marketing at Dialog Semiconductors, explains that the main reason for these problems is that some bulb designers are unclear about the environment and state of use of the bulb (for example, in closed luminaire systems where air flow is limited, or air freedom). Flowing open luminaire systems), and sometimes poorly designed thermal energy systems are used in applications where air flow is limited, resulting in overheating of the luminaire and greatly reducing the life of the solid state lighting bulb.
