Under the background of the government's promotion of green energy-saving lamps, energy-saving lamps have gradually become the first choice for urban households to replace incandescent lamps. The recent radical view in the market is that LED lights are more energy efficient than energy-saving lamps and are expected to completely replace the market position of energy-saving lamps in two or three years. It is noted from the feedback of the readers that when consumers select energy-saving lamps in the store, the staff of the merchants enthusiastically recommend them to purchase LED bulbs. Is the LED light really more energy-efficient, environmentally friendly and longer lasting as the business advertises? Has the home LED era arrived? Experts said that household LED lights are still in a period of rapid development, home selection and slow.
Unannounced visits to the store to eagerly sell LED lights Recently, the reporter visited Shilihe Lighting City and Jiahe Jiamei Lighting City found that although the current sales in the store are still mainly energy-saving lamps, but in most stores selling ordinary lamps and light bulbs, From the point of view of product promotion, LED bulbs are basically in the same position as energy-saving lamps, and for consumers who purchase energy-saving lamps, sales people will recommend LED bulbs.
The salesperson's propaganda reasons basically include LED bulbs, new types, brighter than energy-saving lamps, more power-saving, and longer life. Sales staff will also turn on the lights demonstration. The reporter saw at the scene that the brightness of the 3W LED bulb was indeed similar to the brightness of the 8W energy-saving lamp, and there was no obvious difference in the visual inspection.
In addition to LED bulbs that can replace incandescent and energy-saving lamps, LED light sources seem to cover all of the light source requirements in the home. In major physical stores (including Carrefour and other large supermarkets) and Jingdong, excellence and other electronic malls, spotlights, downlights, ceiling lamps, ceiling lamps, table lamps, nightlights and other common household lighting have LED products. Ai Diguang lighting product manager Yang Wei said that LED lights have exceeded the specification limits, no matter what specifications of incandescent lamps and energy-saving lamps, you can find the corresponding LED lamp replacement in the market.
The price gap is difficult for big-name reporters to find that compared with the high concentration of energy-saving lamps, LED bulb manufacturers rarely see NVC, Philips, Op. In the authorized stores of Schneider, Opt and other brands, the LED bulbs sold are also produced by unknown manufacturers; the brand-name LED desk lamps and LED tube lamps are mainly exhibits. The salesperson's explanation is: These big brands are all producing LED bulbs, which have not been officially put on the market.
According to the reporter's rough statistics, among the more than 10 stores visited, only 3W LED bulb products are sold, and the brands sold by different stores are different, but most of them are products of unknown brands, and the price difference between products is very high. Large, a 3W LED bulb lamp prices range from 28 yuan to 135 yuan. One of the products is priced at 135 yuan. According to the salesperson, this is the company's patented technology products, so the price is also higher.
Compared with the well-known brands of energy-saving lamps, the price of LED bulbs is no more than 15-30 yuan. In this regard, the salesperson admitted that this is a common reflection of consumers, but the salesperson said that after many consumers understand it (after the seller has recommended it by the salesperson), they will buy it.
LED lighting or Light Emitting Diode, a solid-state semiconductor device that converts electricity directly into light. In terms of lighting, LEDs have unique advantages. The merchants, production companies and association experts interviewed by the reporter all agreed that LED products are the future development trend of the lighting field. Wang Xiaoying, secretary general of the Beijing Lighting Society, said that in terms of longevity, the standard index of LED chips can indeed reach 20,000-hour hours. The average bulb life is 25,000 hours, and the life of the energy-saving lamp is about 8000-10000 hours. In terms of light efficiency, the brightness of LEDs is indeed higher. Generally, a 5.5-watt LED lamp is equivalent to an incandescent lamp of 70-80 watts.
As for environmental protection issues, Wang Xiaoying said that compared with mercury-containing energy-saving lamps, there are mercury pollution hazards in the later recovery. Although LED lamps also contain harmful metals, they are relatively easy to handle and more environmentally friendly.
In addition to the above features, Philips Lighting China market director Yu Yongtao said that for home, because LED lights can produce different color temperature and color, you can match the home decoration style, create a different home atmosphere, which vase LED lights, ice wine lights, candle lights It is a master of home atmosphere.
Whether home technology is mature or not, household LED lighting has come from the industrial development. After the 2008 Beijing Olympic Games, LED lighting gradually moved to the home market. Chang Yi, secretary-general of Beijing Lighting Association, said that the first market for LED is urban lighting, and the second market is display devices, such as display screens for instrumentation and home appliances; the third largest market is backlighting for TVs and mobile phones. Home lighting accounts for a small proportion.
Chang Yi believes that most of the current LED home lighting is in the experimental stage, and there are not many mature products. In addition, the problem of light decay of LED illumination is more serious, and the color reproduction of LED lamps is not so good with time and temperature changes. He said that if the chip quality is better, there will be less light decay, and the United States, Japan and Germany are all doing technical research in this area. He also pointed out that with the continuous development of LED lamp technology, various standards for LED lamps are gradually being enriched and improved.
Philips Lighting, which has won the US Department of Energy (DOE) LPrize competition award for its successful development of LED light sources that can replace traditional 60W incandescent bulbs below 10 watts, also said that it will produce an ideal light source that can replace traditional incandescent bulbs. Mass production requires overcoming the many challenges of integrating various innovative technologies. According to the reporter, the current product has been listed in the United States, and the price is nearly 400 yuan. The price of the small prince products, which is about 10 lower than the indicators of the product, is 250-300 yuan. It can be seen that letting mature LED products enter home lighting at an acceptable price, enterprises still need to work hard.
The product quality is not good as a new light source with energy saving, long life and environmental protection. The experts and enterprises interviewed have affirmed the development prospect of LED, but for home lighting, consumers should choose carefully.
A lighting company said that many LED home lighting products are currently produced by LED semiconductor companies. These companies lack the knowledge of lighting, and some products made by LED technology have different quality. In addition, the replacement of LED chips is very fast, manufacturers often only mark the life provided by LED chip suppliers on the packaging. In fact, the life of an LED lamp is not equivalent to the life of an LED chip.
Chang Yi pointed out that at present, the country has safety standards for lamps, but there are no performance standards, and there are not many manufacturers who actively carry out performance testing and quality certification before leaving the factory. This will inevitably lead to products with disparity in price and quality in the market. At the same time, the situation of many production enterprises, many products, and large price differences have also caused consumers to choose at a loss.
