LED domestic market outlook, resulting in the LED business at home and abroad merger integration and downstream industry chain accelerated, attracting a large number of investors have entered the industry, the climax of the investment industry appears again, for a time a wide range of lighting products throughout the market . LED state of the market compared to the previous year, this year s LED investment boom presents a version of the cooling state lighting giant is no longer a high-profile face of the LED industry, but the direction of the publicity back to the energy-saving lamps, but the focus is on the LED After all, by the national policy to guide the development of energy-saving LED light source are lighting the mainstream of development. Another reason for the LED market confusion for investors blindly Herd, another more important reason is that market mature enough. Spot checks of a domestic LED lighting products, LED luminous efficiency of the domestic, the color is relatively low. And the source of the chip is mainly dependent on imports, so that the cost of the product becomes greater. Compared to the same brightness LED, than the price higher, so that with the energy saving compared to weaken the LED efforts to attract the right consumers. The lack of core competitiveness-oriented terminal, expensive, filled with defective lighting market in the face of competition from foreign-funded enterprises, many of the local market advantage becomes tasteless. However, a new starting point in the lighting business, only to break the bottleneck of the technology in order to find more outlets, this is a trend in the development of LED industry, innovation research and development core technologies in order to step ahead of others in the lighting market .

Consumers \\ needs are constantly changing to meet consumers\\ requirements, lighting products also need to constantly retreat once new. With the continuous progress of modern lighting technology, new materials, new processes, new technology widely used, as well as in-depth study of a variety of lighting principle and use of the environment, breaking the previous simple lighting, lighting the traditional concept of the environment, greatly a wealth of modern lamps, lighting and the lighting environment, the performance of the power and beauty means. Through the brightness of the lighting place, with light curves requires the function of lighting computer-aided design, structural design, so that the lamps meet the practical needs and maximize their light source efficacy under the premise, pay more attention to lighting on the appearance of decorative aesthetic effect , thus forming a four trends of development of modern lighting.

The application of energy efficient light sources

In recent years, with the promotion of energy-efficient lighting, energy-efficient lighting design has become the greatest concern of lighting manufacturers, and recognize that the lamps to achieve energy efficient, the first energy-saving light source should be used, which is the premise to promote energy efficient lighting; followed by the effective utilization in accordance with the size and shape of the energy-saving light source designed lamp optical system, improve lighting and decorative effect.

Lamps integrated technology development attention

With the development and application of the integration of lamps and luminaires, electronic ballasts for lighting electronics technology is the rapid development of a variety of integrated devices and the computer control system of lamps and lighting systems has made significant progress lamps and lighting dimmer, remote control light and color are greatly improved.

Modern lamp dimmer means more advanced than ever before, convenience and flexibility, in addition to set the dimming device and switch gear in the fixture, but also with an integrated IR receiver or remote control dimming device to cast light source dimming or use the computer programming dimming. This dimming method is applicable to the current ceiling transformation, and existing dimming system can be implemented in different places in the following ten stepless dimming and delay lighting.

Use the scene selector and light and low voltage lighting system to work, combined with the usual connection to the flexible lighting design and multi-point control. This scene dimmer and long-range field controller multi-channel installation, random combination for conference rooms, museums and other places, convenience, flexibility, control effect is significant.

Use of the remote computer stations and indoor computer lighting control system can be used with natural lighting levels, day and night time and the user\\ s requirements, and automatically change the state of the indoor decorative lighting source, change the entire lighting system parameter setting, and monitoring to achieve through the screen. This control method is suitable for hotels, shopping malls and other civilian facilities.

The integrated technology is the gradual integration with the development of modern lamps. A variety of lamps integrated circuit, the energy saving effect is remarkable. Integrated circuits such as directional lighting spotlight with the production of a U.S. company, the lighting energy consumption decreased substantially, integrated technology will become the trend of modern lighting design.

From simple illumination to the development of both lighting and decoration

Modern lighting is in the transition from \"light up\" to \"pretty up\", more emphasis on the decorative and aesthetic effect. The modern lighting design and production application of modern science and technology, combining the classic styling with contemporary, reflecting the achievements of modern lighting technology. European style of decoration is generally optional Crystal series of lamps to highlight its luxurious. The characteristics of the development of composite lighting: in order to ensure the lighting conditions and visual comfort, lighting mostly with various series of complete selection of accessories so that users need to adjust. Emphasis on personality, and also stressed that coordination and the surrounding environment. In short, an important symbol to reflect the level of modern lighting products one is to see its ability to coordinate the whole environment at the same time to highlight their features and decorative effect.

To the development of a multi-function direction

With the development of compact light sources, and new technologies, new processes, ballast lamp miniaturization of electrical accessories, modern lamps are small, practical, multi-direction.

compact fluorescent lamps increased range of applications in modern lighting. The first fluorescent lamp is mainly concentrated in table lamp development, is now gradually extended to the development of various types of lighting, a variety of lighting situations and functional lighting lamps. We can make a simple categorization: low-power compact fluorescent lamps are generally used in table lamps, grille with; high-power compact fluorescent lamps are generally used in a variety of road lights, garden lights, lawn; three compact fluorescent lamps with most of the electronic ballast and with a uniquely designed reflector, high luminaire efficiency, coupled with the computer and infrared remote control devices, it is even more economical and practical.

The small lamp design is more compact and reasonable. : English Thorne produced a mini-spotlight, this light each light woven terminals are equipped with a variety of optical accessories, including prisms, lenses, grating, etc., to control the beam, features a unique, compact .

In order to adapt to the flexibility of modern building interior size varied, functional and varied requirements, the use of architectural space as possible, to facilitate people\\ s lives, multi-functional combination lamps came into being. : Ceiling fan lights for home and office, set lighting dimming and fan speed control function, the control system as a whole, both the whole range of dimming of the light source, the implementation of the third gear speed control of fans, convenient and practical . Another example is the multi-functional lighting fixtures for use in the wards, either as background light reception visiting, and both table lamp, a medical examination lights and night nurse rounds lights four kinds of functions.

 Laser (a laser) means light amplification by stimulated emission, is a high quality light source.

    The characteristics of the laser: 1. Directional monochromatic. Energy concentration. Coherence
 
    Laser biological tissue effects:

    Photothermal effect. Photochemical effect. Electromagnetic effects 4. Pressure effect
  
    Laser biological tissue: a high-power laser coagulation, burning in addition to two low-power laser irradiation of vaporization
  
    Three. "Knife" finely divided
 
    Laser is a nature originally does not exist, due to the shock issue has good directionality and high brightness, good color and good coherence properties of light. Physicists to generate the laser mechanism traceable to the 1917 hypothesis of Einstein to explain the blackbody radiation law, the light absorption and emission via stimulated absorption, stimulated emission and spontaneous emission are three basic processes. As we all know, any kind of light emission is related to its state of motion of material particles within. When the particles (atoms, molecules or ions) in the low-en ergy level of absorption of external energy (light) of the appropriate frequency to be excited (stimulated absorption) transition to the corresponding energy level is always trying to transition to a lower level go, the excess energy released form of a photon. Without external photon effect alone released spontaneously (spontaneous emission), then release the light is the ordinary light (such as lights, neon signs, etc.), which is characterized by the size of the frequency of light, the direction and pace of very inconsistent. But if it is under the direct role of foreign photon transition to low energy levels by the high energy level, the excess energy released form of a photon (stimulated emission), the photon is released outside the incident photon frequency, phase, direction of propagation exactly the same, which means that the external light has been strengthened, which we call optical amplification. Obviously, if adopted by the shock absorption, so that the number of p articles in a high energy level more than at the low levels of (inversion), the magnification of this optical phenomenon is more obvious, then there is likely to form the laser.

    The laser is labeled the magic of light, because it is the ordinary light do not have any of the four features.

    Good direction - ordinary light source (sun, incandescent or fluorescent) light-emitting in all directions, the direction of the laser light can be restricted within the solid angle of less than a few milliradians, which makes the illumination in the irradiation direction to improve ten million times. Laser collimation, orientation and distance measurement is to use a good direction this feature.

    (2) high brightness - the laser is of the brightest light only flash can be comparable to the hydrogen bomb explosion instantly strong. The brightness of the sunlight is about 103 W / (cm 2 steradian), a high-power laser output brightness of the sunlight of 7 to 14 orders of magnitude higher. Thus, although the total energy of the laser are not necessarily great, but since the energy is highly concentrated, it is easy to generate high pressure and tens of thousands of degrees Celsius or even millions of degrees Celsius in a tiny point. Laser drilling, cutting, welding and laser surgery is to use this feature.

    3 monochromatic - the light is an electromagnetic wave. The color of light depends on its wavelength. Ordinary light source light emitted typically contain a variety of wavelengths, the mixing of the various colors of light. Sunlight contains red, Tang, yellow, green, green, blue, purple seven colors of visible light and infrared light, UV and visible light. The wavelength of a laser, only concentrated in a very narrow spectral band or frequency range. Such as helium-neon laser wavelength of 632.8 nm, the wavelength range of less than one ten thousandth of nano. Monochromaticity of the laser, for precision instruments to measure and motivate some chemical reactions and other scientific experiments provide a very favorable means.

    Coherence - interference is a property of the wave phenomena. Laser-based, highly directional and monochromatic features, it is bound to the excellent coherence. This feature of laser holography to become a reality. - The so-called laser technology, is to explore these features to develop a variety of laser and explore the application of laser technology general benefit of mankind. Since 1960 successfully developed the world s first ruby ??laser, China has also successfully developed in 1961 made the first ruby ??laser, laser technology is considered the 20th century, following the quantum physics, radio technology, nuclear technology, semiconductor technology, electronic another new major scientific and technological achievements in computer technology. 30 years, laser technology, the rapid development of not only the development of the various characteristics of a variety of lasers, laser applications, expanding the field, and formed a compact disc juk ebox, laser medical treatment, laser processing, laser holography, laser photo-typesetting printing , laser printing, and laser weapons and other emerging industries. The rapid development of laser technology, making it one of today s new technological revolution, "leading technology".
