LED indoor lighting faces "three major tests"
From the actual use situation, LED indoor lighting is generally divided into industrial lighting, commercial lighting and household lighting. Industrial indoor lighting is an LED for early entry and demand market. It emphasizes safety, energy saving and longevity in product demand. For example, industrial and mining lamps generally adopt high-quality and energy-saving routes to save cost; HTIN focuses on scene effects. And the user experience, sometimes for a variety of application environments, introduced the color temperature display of special lamps from different angles; and home lighting tends to pay more attention to cost performance, obvious FE. The current field of application is that tube lamps and light bulbs based on home applications have entered the era of low cost.
Quality reliability needs to be improved
In recent years, the proportion of LEDs in the field of general lighting has increased rapidly. It opens up a growing field for the application of LED indoor lighting in the commercial field. This market is usually used mainly for engineering procurement, and the demand for products is very large, so it has become a key market for all manufacturers. On the other hand, the general civil lighting market has also been fully open, and its development speed cannot be underestimated. More and more manufacturers have introduced more mature LED lamps, and some products have broken through the traditional lighting category in function and design.
However, with the rapid development of indoor lighting, there is still a big gap between the application market and the quality of LED lamps. LED indoor lamps have the advantages of energy saving, long life, safety, etc. "Wu Hongfeng, Sales Director of International Sales Department of Jiangsu Stable Electro-optical Co., Ltd." In many practical situations, LED users are not fully aware of LEDs. Some companies are rapidly attracting users' attention and driving the rapid development of the market. Sharing, using poor products and technologies, such as: for brightness, give up life; save energy, give up security, makes part of the feedback message in the terminal market is LED lights are good, but most are bad, the price is not cheap. In response to the negative impact of this short-term interest, he further pointed out that a new round of changes in the lighting market is taking place, including the friction between the cognitive differences between traditional lamps and LED lamps. Once the advantages of LEDs are artificially manufactured, it will make the market more difficult, especially in the LED application market. Therefore, industrial enterprises urgently need to consciously abide by technical standards and quality standards, and create a healthy industrial development mode.
As an example of the current thermal management problem that has a large impact on the quality of LED indoor bulbs, although LED lighting can significantly save energy, the total life of the bulb can be estimated to be 30,000 to 50,000 hours, but in fact, many components. In LED drive circuits, especially electrolytic capacitors, they age with increasing temperature. The excess heat in the modified luminaire results in a significant reduction in the life of the solid state lighting bulb, which also allows consumers to discount the expected quality of the LED lamp.
Hubie Notohamiprodjo, director of marketing for solid-state lighting products at Semiconductor Co., Ltd. explained: "The reason for these problems is mainly because some bulb designers don't know the use and status of the bulbs (for example, in limited enclosed fixtures). Air flows, and they are free. The airflow is in the outdoor light system. Therefore, sometimes in a limited air flow application, a poorly designed thermal energy system is used, causing the lamp to overheat, which greatly reduces the life of the solid state lighting bulb.
