LED lighting has many advantages

Recently, the smog weather that has appeared in many places has once again caused everyone's attention to the natural environment. Green, environmental protection, and energy saving are even more than empty words and big words. The incandescent and LED lights that have lighting are characteristic of LED lighting. Obviously more in line with the requirements of environmental protection.

Compared to LED lighting fixtures, the luminous rate of incandescent bulbs is only 5%, and the remaining 95% translates into heat consumption. The LED lamp with environmental protection and energy saving not only has high luminous efficiency when the lamp is turned on, but also has a long service life, and can also save 90% of the power. More importantly, it does not contain toxic substances such as mercury.

In addition to time and place, people's wishes have strengthened the development of LED lighting. Recently, the National Development and Reform Commission and the Ministry of Science and Technology jointly issued the latest "Semiconductor Lighting Energy-saving Industry Plan." "Planning" shows that by 2015, all 60W incandescent lamps used in general lighting will be eliminated, the market share will drop below 10%; the market share of traditional high-efficiency lighting products such as energy-saving lamps will be stable at around 70%; LED functional lighting products Market share of more than 20%. The introduction of the "plan" led LED lighting to be superior to traditional lighting such as incandescent lamps.

LED lighting is widely used Edison invented the incandescent lamp, lit a bright light in the dark night, since then opened the home of lighting history. For a long time, incandescent lamps have also been playing the role of lighting. However, in 1962, the United States General Electric developed the world's first red LED, 70 years, the emergence of green, yellow and orange LED, 80 years, the development of new materials GaAlAs, so that the red LED luminous efficiency of 10Lm / W, until 1993, Japan's investment in the sub-globalization led to the emergence of blue LED, natural red, yellow, and blue primary colors together. This means that in addition to incandescent lamps, LEDs can also assume the function of lighting, and can also be applied to a wider range of fields.

At present, LED is mainly used for information display billboards, traffic lights traffic lights, commercial lighting, table lamps and other general lighting and military lighting and medical surgical lamps and smart lighting. With the advancement of technology and the development of social trends, people also want to give LED lighting fashion and art, but fluorescent lamps and incandescent lamps are far behind in this respect.

The promotion of LED lighting products meets the spring breeze and the south bank of the Green River. China's LED industry policy is favorable: In early January, LED lighting products were first selected for the “Public Procurement List for Energy-saving Products” publicized by the Ministry of Finance. On February 17, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Housing and Urban-Rural Development, and the six major ministries and commissions of the State Administration of Quality Supervision, Inspection and Quarantine formally issued the “Semiconductor Lighting Energy-Saving Industry Plan”, which stipulates that the development goal of the LED lighting energy-saving industry is the average annual output value. It increased by 30% to reach 450 billion yuan in 2015 (of which 180 billion yuan for LED lighting applications). Bathing policy spring breeze, LED stock market also ushered in a good start, however, LEDinside that the promotion of LED lighting products is a long way to go, in order to share the traditional lighting with the spring, still need to remove many obstacles.

1. How to balance cost and quality control?

Because the upstream core technology is subject to international companies, and the capital investment is large, the middle reaches are oversaturated and the profitability is low. Therefore, many small-scale, small-scale traditional lighting companies have even completely stopped the entry of light entry companies. Low downstream LED lighting industry. Many companies often take advantage of the speculative mentality and do not seek technological breakthroughs. They only seek puerile, copying, and plagiarism. The phenomenon of repeated production is serious. In addition, some dealers have strict control over prices and even offered to sacrifice quality to reduce costs. This also puts enterprises in a dilemma: if they meet the requirements of consumers, doing a low-end product will undermine the company's brand image; if it does not reduce costs, profits cannot be guaranteed. In this case, "What should we do?" has become a problem for most of the industry to think hard.

The technology and the channel are elbow, and the LED chess is on the opponent. At present, energy-saving lamps have become the main force of the home lighting market, LED lighting is the strongest opponent. Compared with LED, energy-saving lamp technology is mature, the product is stable, the price is only about 10 yuan, more likely to be favored by dealers and consumers.

Due to the characteristics of the point light source, the LED lamp needs a high luminance when it is used for indoor lighting. To achieve a certain space lighting brightness, it is difficult to avoid the glare of light; with the lamp shade, although it can soften the light to a certain extent, It is easy to cause heat dissipation problems. The LED luminous efficiency will decrease to dark when the temperature rises. In addition, blue light that damages the human eye is hidden in the LED light. These technical defects also make it difficult for LED lamps in the home lighting market to rival traditional lighting fixtures.

At the same time, there are fewer types of LED products, and the light intensity is insufficient, and the LED lighting effect of a single LED lamp is single. Therefore, there are many situations in which the LED lamp is used as an auxiliary light source. Although most shops are selling LED signboards, they are actually poorly stocked and offer less choice. Only when the customer asks, they will only buy goods from other families, and even turn to sell the dog meat. LED franchise, the main product is based on traditional lighting.

In addition, some small manufacturers, low-cost competition, product quality is not reliable, resulting in high return rate of customers, in the long run, will destroy the overall reputation of the LED lighting market. For this reason, distributors also have insufficient confidence in the distribution of goods, and they have a long way to go for LED products.

2, limited lighting effects, limited LED lighting promotion this year's Spring Festival Gala stage lighting design, so that people recognize the LED lighting to bring the stage effect. In the artistic process of achieving beauty, LED technology plays an increasingly important role. However, at present, the proportion of LED products used by lighting designers is still very small. Many domestic designers also reflect that, under certain requirements, due to the self-illumination, the area where the LED light sources project is not far, although there are strong The effect of light, but the effect of light and shadow formed by the LED spot light is not as good as that of a metal halide lamp, and the ideal height and distance cannot be reached. In addition, at this stage, LED products can only replace traditional spotlights such as MR16, QR111, PAR30, and PAR38. The lighting effects cannot completely replace traditional lamps such as high-pressure sodium lamps and metal halide lamps.

At the same time, in actual projects, the high price of LED products also determines that it is difficult to promote in large areas. According to industry insiders, the use of LED light strips, downlights, spotlights and other products can achieve the best engineering design results, but the project's Party A budget is limited, the cost of using LED products will rise, so the owners generally require Make partial adjustments based on the budget. In addition, the effect of traditional lighting products is not necessarily worse than that of LEDs. Therefore, the owners still choose traditional products as the main products.

In the recent period of time, various social circles have paid attention to the topic of "waste on the tip of the tongue." Many companies in the LED industry have sacrificed product quality, seized at a low price, and homogenized the phenomenon of repeated manufacturing. Is it not a waste? The phenomenon of massive waste of power resources and light pollution caused by the constant light of landscape lighting also deserves our attention. The newly released "Semiconductor Lighting Energy-Saving Industry Plan" also clearly points out the advantages of LED lighting: compared with traditional lighting products, LED road lighting saves more than 30%, indoor lighting saves more than 60%, and backlighting saves 50%. Above, landscape lighting saves more than 80% of electricity and achieves annual electricity savings of 60 billion kwh, equivalent to saving 21 million tons of standard coal and reducing carbon dioxide emissions by nearly 60 million tons. To enable consumers to truly see the economic benefits of LED energy saving and environmental protection, LED companies still need to continue their efforts in terms of quality, technology, price, and channels.
