New technology of LED white light packaging leads the new trend of LED lighting

As the concept of "energy conservation, emission reduction and low-carbon economy " has gained popularity, green and environmentally friendly LED white light lighting products have also entered the public's field of vision. After several years of development, LED white light packaging technology has become increasingly mature, and the application market demand has continued to increase. LED has gradually become the brightest new star in the lighting world and a revolutionary light source that replaces incandescent lamps and fluorescent lamps.
National policy: vigorously support the gradual elimination of incandescent lamps

Recently, the National Development and Reform Commission announced the "China's Roadmap for Eliminating Incandescent Lamps (Draft for Comments)", which pointed out that from October 1, 2012, China will ban the sale and import of 100-watt and above ordinary lighting incandescent lamps; from October 1, 2014, it will ban the sale and import of 60-watt and above ordinary lighting incandescent lamps, publish halogen tungsten lamp energy efficiency standards, and prohibit the production, import and sale of halogen tungsten lamps below the energy efficiency limit; from October 1, 2016, it will ban the sale and import of 15-watt and above ordinary lighting incandescent lamps. The scope of elimination is ordinary lighting incandescent lamps, and the specific types are Power supply Voltage is 220V; lamp caps are E14, E27 screw-type and B22 bayonet-type. Among them, the target products for elimination do not include reflective incandescent lamps, spotlights, decorative lamps and other types of incandescent lamps and special-purpose incandescent lamps. The release of the roadmap brings a good development opportunity for LED and will accelerate the popularization of LED lighting . The good expectations of all walks of life for LED white light lighting have turned it into an attractive big cake, which has once again attracted countless capitals to chase it frantically. The large packaging companies in the domestic LED industry have also significantly adjusted their development strategies and actively laid out the white light device market. As a leading company in the LED industry, Leman Optoelectronics has closely followed the market development trend and actively developed new white light packaging technologies, striving to seize market share in new fields.

Industry status: The technology is immature and the price is not accepted by the market

White light LED devices have long life, strong structure, low power consumption, flexible dimensions, energy-saving and environmentally friendly characteristics, and can contribute to the improvement of the ecological environment. They are widely used in lighting and backlight sources. They are an extremely important field in the optoelectronics industry and a link between upstream chips and downstream applications. Due to the broad development prospects of white light packaging and the low capital threshold, a large number of companies have entered the packaging field, and the competition is extremely fierce. As a result, the current LED white light products on the market are positioned in the middle and low end, are highly homogenized, and are caught in a price war crisis. Leman Optoelectronics R&D personnel analyzed that the emerging industry that looks "thriving" to outsiders is actually undercurrents of crisis. LED products have problems in many aspects such as luminous efficiency , heat dissipation, color rendering, and patent infringement. Compared with the performance of high-efficiency fluorescent lamps and high-sodium lamps, the power and luminous efficiency of LEDs not only do not have an outstanding advantage, but there is still a certain gap; due to poor chip heat dissipation, poor material and structural processing, most products have poor heat dissipation performance; the color rendering of LED white light is not high, and the color of objects is easily distorted under LED lights ; in addition, many domestic products have patent infringement problems. At present, most core technologies are still in the hands of well-known foreign companies. For example, Nichia ’s process of making white light by adding blue light and yellow phosphor has made many domestic companies take risks; the most critical problem is that although the life of LED lighting is longer than that of incandescent lamps, the price is much higher than that of incandescent lamps. It is not accepted by the market now. Only when the white light packaging technology matures and the cost decreases, the price will drop significantly.

Leman Optoelectronics: Technological innovation leads the new trend of LED lighting

At present, most domestic packaging manufacturers mainly produce low-end and mid-range products, and engage in vicious competition with low prices. As a leading enterprise in the LED industry and the first listed company in Shenzhen, Leman Optoelectronics has always occupied the mid-to-high-end market with leading technology. It is now focusing on the development of new white light packaging technology. In response to the problems of white light devices in the industry, Leman Optoelectronics recently launched the "Daytime" series of products, including high-brightness vertical thermal conductive SMD3528, 20mA lighting 8.5LM, luminous efficiency 130LM per watt; 30mA lighting 12.5LM, 3000 hours of zero attenuation. Adjustable color temperature High-display SMD5050, color temperature adjustable in the range of 3000-8000K, Ra85 or so. Effectively solve the problems of light efficiency, heat dissipation, color rendering of LED white light devices, and specially develop SMD for the Japanese market, all Japanese patented materials, no hidden dangers of intellectual property disputes. Xu Gang, Sales Director of Ledman Optoelectronics Lighting Devices, said that the company is a leading professional, international, high-quality LED manufacturer in China, and has always implemented the blue ocean strategy and differentiated product strategy, and refused to engage in price wars. After the company went public, its scale continued to expand. In addition to the traditional packaging business, it has gradually extended to LED lighting, and has begun to develop vertically while developing horizontally. This "Daytime Series" is the starting point for Ledman Optoelectronics to rise in the field of white light packaging. In the future, there will be more outstanding products launched, and it will continue to maintain its position as a leader in new fields and lead the new trend of LED lighting with new technologies.
