Recently, the National Development and Reform Commission issued the "Notice on Strengthening Work to Ensure the Implementation of the Tasks of Energy Conservation and Emission Reduction in 2013". According to the spirit of the "Notice", relevant departments will promote 130 million high-efficiency lighting products. It is foreseeable that LED products are constantly replacing traditional lighting products. In contrast, LED lighting products have significant advantages such as long service life, high luminous efficiency, more energy saving and environmental protection, no stroboscopic, no radiation and low efficiency.
In the market survey, the reporter found that today's LED lights can not only protect your eyesight, but also protect your vision. Progress has also been made in technologies such as using LED lights to access the Internet. In addition, with the maturity of LED technology, product prices continue to be reduced, the promotion surface will become larger and larger, and in the future, the application field of LED lamps will become more and more extensive.
"No Blu-ray" into a sales signboard
In the lighting sales area of ​​a large home store outside the West Fourth Ring Road in Beijing, the reporter saw that a variety of LED lights have occupied half of the country. The reporter entered a comprehensive lighting store, where the desk lamps are varied, with student eye lights, LED table lamps, ordinary table lamps, etc., as well as multi-function table lamps such as touch dimming, folding, charging, and clamping on the bed. .
The owner told reporters that at present, most consumers choose the desk lamp in addition to the price factor, the most considered is the "eye protection" problem. "Many people come to buy lamps for their children and learn to use them, so whether or not they have an impact on the eyes has become the most important consideration. The price has become the second." The owner introduced that many people now choose LED desk lamps when they buy lamps. "The price is not expensive, a little better than 200 yuan, and save electricity." The owner took a few LED lights for the reporter to pick, the reporter saw that most of the LED table lamps are domestic brands, such as, long-term, complex Light, Boshi, Yage, Yaxin, Gaoliang, Tongjian, Kangming, Good Vision, Xiao Erlang, etc., the price also ranges from 20 yuan to 200 yuan. Although there are international brands such as Philips and Osram, the varieties are relatively small, and the price is nearly double that of domestic brands.
For the previous question about "LED light blue light source ruined", the reporter also asked the owner. Some media reports have caused serious blue light overflow problems in many LED lamps. Long-term use will cause irreversible damage to the human retina, which may even lead to blindness. Most LED luminaires on the market use blue light from the chip to excite yellow phosphors to reconcile into white light. Therefore, the blue light problem of LEDs is particularly prominent.
The owner told reporters that some high-quality LED lights have already solved these problems. The LED eye protection table lamp of a domestic brand is marked on the introduction: the first eye-protection reading lamp that eliminates the blue light hazard in China; no electromagnetic radiation, no ultraviolet light, no glare, no stroboscopic, real health eye protection table lamp. The reporter saw that many LED desk lamps with a price of around 200 yuan are marked with "no blue light". In addition to the desk lamps, many LED ceiling lamps have also launched products without blue light. "No Blu-ray" has become a selling point for many companies to promote their products, and even directly labeled "no Blu-ray" on advertising slogans to attract consumers.
"Color temperature parameter" becomes the next focus?
In the lighting store, the reporter also found that many LED lights also marked the "color temperature parameters." What does the "color temperature parameter" mean? According to professionals, the natural light is high at noon, and the color temperature is low in the morning and dusk. Due to the high blue light content in high color temperature lighting products, the use of such products in the office space is beneficial to boost the spirit. However, if used at night, it may affect sleep, causing the biological clock to be disordered, thereby reducing human immunity.
In this way, while paying attention to the potential damage of the LED blue light to the retina, we must also pay attention to the "color temperature parameter." The reporter saw in a product introduction that the color temperature of the LED without blue eye protection lamp is "4100K", while the color temperature of another brand LED table lamp is "5500K-6500K". There is also a LED eye protection lamp with a price of more than 600 yuan, which is marked as "warm white (2700K - 3200K)".
For the labeling of color temperature, the owner said that the color temperature does not mean the quality of the product. "The average person does not feel any difference." However, the reporter searched on the network for "color temperature parameters" and found that "rich blue" LED The influence of lighting products, that is, high color temperature lighting products on the human body's rhythm is still a frontier topic. Zhang Haijun, honorary chairman of the Shanghai Lighting Society, suggested that the color temperature of indoor LED lighting products should not exceed 4000K, and LED lighting products with color temperature of 5000K and above should be avoided.
In this regard, some companies have also introduced LED lights that can be color-toned, but the price is much more expensive than ordinary products. For example, Philips Coolxiang 30086LED eye protection main function can adjust the color temperature, "according to personal habits, easily adjust the brightness and color temperature (3000K-6000K)." However, its price of nearly 700 yuan is indeed not low. There is also a domestic LED table lamp that can realize yellow, white and natural light three-color temperature dimming.
LED lights can go online?
In a lighting market near Beijing Guanzhuang, a store gave the consumer Mr. Shan a demonstration of the Internet function of LED lights. Store introduction, no need for WiFi signal, as long as a light LED light can achieve wireless Internet access. The seller turns on the LED light and turns on the wireless connection in the phone settings. The phone shows that the network connection is successful. It is reported that this kind of Internet access is achieved through light waves.
Previously, according to Shanghai media reports, researchers at Fudan University realized the technology of using the visible light transmission network signal in the house in the laboratory. According to reports, the network signal is connected to a 1 watt LED light, and the four computers under the light can be connected to the Internet, with a maximum speed of 3.75G and an average network speed of 150Mbps. This form of using LED lighting to access the Internet is called visible light communication (VLC).
Compared to WiFi, visible light communication is also known as LiFi. In fact, domestic technology is not the first time in the world.
As early as 2011, Harald Hass, a professor at the University of Edinburgh in the United Kingdom, proposed this concept at the TED Global, and in October 2012 realized the use of optical transmission of data. Technology.
However, domestic LiFi technology, whether it is the highest rate of 3.75Gbps or the average rate of 150Mbps, is not behind the world. Moreover, the width of the visible light spectrum reaches 10,000 times the radio frequency spectrum. This means that visible light communication can bring higher bandwidth. Another benefit is that there is no need to add more infrastructure.
