White light encapsulation new technology leads the new trend of LED lighting

With the deepening of the “energy-saving, emission-reducing and low-carbon economy”, green LED white lighting products have also entered the public view. After several years of development, LED white-light packaging technology has become more mature and the application market demand has been increasing. LED has gradually become the brightest star in the lighting world and has become a revolutionary light source to replace heat lamps and fluorescent lamps.

National policy: Strong support for the phase-out of incandescent lamps

A few days ago, the National Development and Reform Commission announced the “China Road Map for Phase-out of Incandescent Lamps (Draft for Soliciting Opinions)”. The article points out that from October 1, 2012, China will ban the sale and import of incandescent lamps for general lighting of 100 watts and above; From the 1st of the month, it is forbidden to sell and import incandescent lamps for general lighting of 60 watts or more, to issue halogen lamp efficiency standards, and to prohibit the production, import, and sale of halogen lamps below the limit of energy efficiency; effective from October 1, 2016. It is prohibited to sell and import incandescent lamps for general lighting of 15 W or more. The scope of elimination is incandescent lamps for general lighting. The specific type is the power supply voltage of 220V; the lamp head is E14, E27 screw type and B22 bayonet type. Among them, the elimination of target products does not include reflective incandescent lamps, spotlights, decorative lights and other types of incandescent lamps and incandescent lamps for special purposes. The release of the roadmap brings a good opportunity for LED and will accelerate the popularity of LED lighting. The bright expectations of LED white lighting from all walks of life have turned it into a tempting big cake that once again attracts numerous capital enthusiasts. Domestic packaging companies in the LED industry also significantly adjusted their development strategies and actively deployed the white-light device market. As the leading LED industry company, Lehman Optoelectronics closely follows the market development trend and develops new technologies for white-light encapsulation in an effort to seize market share in new areas.

Industry status: Immature technology prices are not accepted by the market

White LED devices have a long life span, a robust structure, low power consumption, and flexible dimensions. They have energy-saving and environmentally-friendly features and can contribute positively to the improvement of the ecological environment. It is widely used in lighting and backlighting, and is an extremely important field in the optoelectronics industry. It is also the link connecting upstream chips and downstream applications. Due to the broad prospects for the development of white packaging, and the relatively low funding threshold, a large number of companies are flooding into the packaging industry and the competition is extremely fierce. As a result, the current product positioning in the market is low-end, homogenous, and plunged into a price war crisis. Lehman Optoelectronics R&D personnel analysis said that in an emerging industry that “looks prosperous” in emerging industries, the crisis is actually surging. LED products have many problems, such as light efficiency, heat dissipation, color rendering, patent infringement, etc. LED power, light efficiency and high-efficiency fluorescent lamps and high-sodium lamps are not only unobvious, but there is still a certain gap; due to the chip Poor heat dissipation, poor material and structure handling, poor thermal performance of most products; LED's color rendering is not high at present, articles are easily distorted under LED lights; in addition, many domestic products have patent infringement problems, most of the core Technology is still in the hands of well-known foreign companies. For example, the technology of blue light and yellow phosphors that Nichia holds to create white light has made many domestic companies take risks. The most critical point is that although LED lighting has a longer life than incandescent lamps, the price is far higher than that of incandescent lamps. Currently, it is not accepted by the market. Only the white packaging technology is mature, the cost is reduced, and the price may drop sharply one day.

Lehman Optoelectronics: Technology Innovation Leads New Trends in LED Lighting

At present, most domestic package manufacturers mainly produce medium and low-end products, and conduct vicious competition at low prices. Lehman Optoelectronics, as the leading company in the LED industry, and Shenzhen's first listed company, has always occupied the mid-to-high-end market with leading technologies, and now focuses on R&D forces. Develop new technologies for white packaging. In response to the existing problems of white light devices in the industry, Lehman Optoelectronics recently launched the "White" series of products, including the bright vertical thermal conductivity SMD3528, 20mA light 8.5LM, light efficiency 130LM per watt; 30mA light 12.5LM, 3000 hours zero attenuation. The color temperature of the SMD5050 can be adjusted, and the temperature range of 3000-8000K can be adjusted. Effectively solve the problems of LED white light devices such as light efficiency, heat dissipation, color rendering, patent infringement, etc., and specially develop SMD for the Japanese market, all Japanese patent materials, no intellectual property rights disputes. According to Xu Gang, Sales Director of Lehman Optoelectronics Lighting Devices, the company is a leading professional, international, and high-quality LED manufacturer in China. He consistently implements Blue Ocean tactics, realizes differentiated strategies, and refuses to fight price wars. After the listing of the company, the scale has continued to expand, in addition to the traditional packaging business, it has gradually extended to the LED lighting, but also in the horizontal development and further vertical development. This series of "White Pelicans" is the starting point for the rise of Lehman Optoelectronics in the field of white light packaging. There will be more excellent products available in the future, and there will still be a leader in the new field, using new technologies to lead the new trend of LED lighting.
