With the rapid development of China's economy, especially the real estate industry continues to heat up, the supporting lighting industry is developing rapidly. With the introduction of LED lighting, the intelligent lighting industry is also ushered in rapid development. Various types of products are emerging in the market. Intelligent switches, lamps, etc. However, the author recently visited and found that the price of LED lamps of different brands is very different, and because there are no relevant standards at present, the uneven quality of products also makes consumers buy as if they are in the fog.
The traditional lighting one-button-one-switch type is too old-fashioned. The master must remember the switch when entering or leaving the room. If you don't pay attention, you will forget to turn off the light and waste energy. Especially when there is an emergency, it is very easy to forget to turn off the lights. If you need to adjust the light, you need to bend over and debug slowly, which is very troublesome. Moreover, the current people's residences are spacious and there are many rooms. If there is no remote control function, the switch lights are really inconvenient.
However, intelligent lighting can intelligently set up all the lamps such as chandeliers, hanging lamps and wall lamps in the home to be scientifically and rationally used, thereby achieving maximum convenience and energy saving effects. For example, it is possible to set up a visitor and return through scene setting. Home, dinner, home, sleep and other modes, according to actual needs and living habits to adjust the use, to meet the needs of people in a variety of life scenarios, enrich the environmental effects, the owner has become more worry-free.
Intelligent lighting not only enriches life, but also saves energy to the utmost. It not only sets the light to people, but also removes the effect of light. It can also take into account the natural light angle during use, so that the light in the dark is strong and bright. The light is weak, so that the overall balance. The data shows that the use of intelligent lighting systems can save ordinary households 20 to 40 electricity bills than originally, which is undoubtedly an irresistible temptation for many families.
But it needs to be recognized that LED is an emerging industry and an immature industry. Due to the rapid development of the industry in recent years, and the lack of uniform standards, the LED terminal market is chaotic, and the products are mixed, and the LED products are also foggy.
A few days ago, the author visited Haicheng's major lighting building materials market and learned that many merchants' understanding of LED products still stays on product prices and appearance and packaging, but they don't know the core things of LED products such as quality, technology and life. .
The author visited the lighting city and learned that most of the merchants have sold LED lighting as the main product. However, the price of LED lamps of different brands varies greatly. Taking 9-watt LED spotlights as an example, the price ranges from 20 yuan to 200 yuan. In terms of service life, many merchants claim that the life of LED bulbs can reach 20,000 to 30,000 hours, and the life span of households is 8 to 10 years. However, the author noticed that in fact, the shelf life of most LED lamps and packaging is only 2 years.
During the visit, the author asked several staff members who sold LED lights, but they introduced the opposite. The light that is generally better for LEDs and the like is very bright and penetrating. A salesperson told the author that the LEDs that are generally better should cost more than 50 yuan. Another staff member told me that good LED lighting, although very bright, but its advantage is that it is very energy-efficient, and also has a protective effect on people's vision, compared to conventional lighting, LED lighting is softer, The more expensive it is, the darker it is. From this point of view, some of the sales staff of LED lighting, their products are different, and there is not much understanding.
According to industry insiders, LEDs currently do not have national standards, and all companies produce according to their own standards. The quality supervision bureau's supervision of LEDs is based only on conventional application indicators, and it is impossible to judge which is better and which is worse, but the energy-saving effect of LEDs is obvious. If used as decorative lights, LEDs can save energy by 60 to 80 than energy-saving lamps. Energy saving 40 to 50 for lighting applications. However, the light decay (light attenuation) of LEDs is also obvious. At present, there are three main problems in domestic LED home lighting. First, the use of aluminum heat sink, if not attached to the LED chip, directly affects the service life; second, the brightness of the brightness requires a controller, the quality of the controller itself is uneven; the third is the drive power A core technology, only a few companies are willing to increase investment in scientific research on this core technology.
Relevant people suggest that consumers should pay more attention to product packaging, price comparison and demonstration effects when choosing LED intelligent lighting. See if there are product trademarks and certification marks, 3C certification, CE certification, etc., in addition to see whether the product's rated voltage, voltage range, color temperature, precautions, safety instructions, applicable environment, etc. are clearly marked; due to the special process in the production of LED lamps Process, the cost is relatively high, the average domestic LED lamp price is above 40 yuan, the import is higher; carefully observe the color change of the lamp, if in a short time, from yellow light to white light, or by White light turns into white light with blue, and such products should be abandoned. Because it is very likely to be a power problem or a light source selection error. In addition, the color of the light should be consistent and not flash. After the LED lamp is lit, the heat dissipation of the product can be detected by touching the surface temperature of the product. If the temperature of the product continues to rise within 1 hour, instead of the temperature being stable for up to 30 minutes, do not select the product because the heat is not Good results in a shortened product life.
