LED lighting market opportunities, a vast space for development. LED lighting applications have been from the past, the development of outdoor landscape lighting LED indoor lighting applications. According to the analysis of the next five years LED indoor lighting development will have an exponential growth trend. Its output value will reach tens of billions of dollars in 2011. In particular, the EU took the lead in implementing the banned incandescent lamp plan in 2009, and the issue of energy conservation has attracted much attention and created a huge market opportunity and optimistic prospects for LED indoor lighting. High-power LED lighting development depends on two major elements: First, the chip itself; Second, lighting technology, including cooling, optical, drive. The first is the chip, at present, LED chip technology is the key to the development of substrate materials and epitaxial growth technology. Base material from the traditional sapphire materials, silicon and silicon carbide, zinc oxide, gallium nitride and other new materials. Whether it is high-power chips for accent lighting and solid-state lighting, or low-power chips for decorative lighting and some simple auxiliary lighting, the key to technology upgrading is how to develop more efficient and stable chips. In just a few years, LEDs have achieved a quantum leap in light efficiency with a series of technological improvements, including chip structure, surface roughening and multi-quantum well structure design. Thin film chip technology is the core technology in the production of super bright LED chips, which can reduce the light output loss of each side and can output more than 97% of the light from the front side through the bottom reflective surface. This not only significantly improves the luminous efficiency of the LED, but also creates superior convenience for the lens design. In fact, since the development of LED lighting has been concerned about its service life, if only rely on the use of low thermal resistance of LED components is not able to build a good cooling system for lighting devices, but must effectively reduce the PN node to the surrounding environment Thermal resistance, in order to greatly reduce the LED PN junction temperature, the successful practice of extending the life of LED lamps and improve the actual luminous flux of the goal. Different from the traditional lamps and lanterns, the printed circuit board is not only the LED power supply carrier, but also the LED heat carrier, so the heat sink and printed circuit board thermal design is very important. In addition, luminaire manufacturers must consider the quality, thickness and size of the thermal materials, the handling and connection of the thermal interface, and more. LED lighting optical design, compared with the traditional lamps, directional and point light is the most typical feature of LED lighting is also the key to the optical design. Through the LED's dual optical design, LED lamps can achieve better light distribution curve. As the current development of LED lighting applications, the largest indoor lighting lighting needs very bright, you can use high transmittance lampshade to improve light extraction efficiency. Or the light guide plate technology applied to the lamp, which will change the LED light source for surface light, not only can improve the light distribution uniformity, but also to prevent glare. Can also be used in conjunction with some condenser lenses or reflectors to highlight the condensing effect of illuminated objects to achieve the desired optical effect. The technical challenges of high-power LED lighting, even though LEDs have shown satisfactory performance in indoor accent lighting and decorative lighting applications, still present a number of challenges in general lighting and ambience lighting applications, including initial cost, low color temperature Light efficiency, color rendering index and system reliability. Cost is a relatively sensitive factor in indoor lighting, especially in home lighting applications. Despite the increasing number of LED lights and increasing luminous efficiency, the problem of high prices persists. However, when the price of LED light source is reduced and the overall system design is optimized, the total cost will inevitably fall. LED lamps to improve light efficiency at low color temperature 4000K below the low color temperature is usually the first choice for indoor home lighting. Warm white light makes the entire environment warmer and more relaxed; while cool white light gives a clean, efficient, bright feel, more suitable for office and outdoor lighting. LED lamps extend the service life, improve system reliability. In general lighting applications, the overall efficiency, lifetime, and reliability of the LEDs must be optimized through system optimization. LED light source: compact, efficient, with a variety of colors and output power to choose from. Power Conversion: Converts AC, battery and other power supplies efficiently to a safe, low-voltage, constant-current power supply. Control and drive: The use of electronic circuits to achieve constant current LED drive and control. Thermal Management: To achieve longer life, LED node temperature control is very important, thermal analysis is also indispensable. Optics: Lenses, reflectors, or light guide materials are the necessary optics for focusing light in the target area. With the rapid development of LED technology and the gradual improvement of LED luminous efficiency, the application of LED will be more and more widely. Especially with the increasingly serious global energy shortage, people are paying more and more attention to the development prospect of LED in the lighting market. LED will be the potential light source to replace incandescent lamps, tungsten lamps and fluorescent lamps. In addition, in the interior lighting design, LED will tend to energy-saving, humane and artistic.
