一. Foreword
Landscape lighting refers to the outdoor lighting project that has both the function of lighting and the function of art decoration and beautification of the environment. Landscape lighting can be divided into garden square landscape lighting, road landscape lighting, architectural landscape lighting, cultural tourism landscape lighting. Landscape lighting usually covers a wide range of categories, requiring overall planning thinking, landscape lighting techniques are diverse, the choice of lighting fixtures is also complex, the overall ability of lighting designers higher requirements.
It is the general trend for LED to replace traditional lighting products due to its advantages of energy saving, environmental protection and easy control. Intelligent lighting system in LED application integrates monitoring, communication, instruction, lighting and other functions, which will play an important role in lighting management of all kinds of urban landscape in the future.
LED (Light Emitting Diode), also known as light-emitting diodes (leds), is the use of solid semiconductor chip as a luminescent material, when put forward voltage on both ends, carrier in the semiconductor compound, release caused by excess energy photon emission produces visible Light, infrared and near-infrared Light, make full use of the LED in landscape lighting engineering of visible Light.
LED light source by virtue of its luminescent close to the point light source, convenient for secondary optical design, light response time is short, easy to be made into a small volume lamps, save installation space and other characteristics of the landscape unique form and space connotation in a variety of ways to show a unique landscape. In recent years, with the continuous development of LED technology, many other related technologies have developed rapidly.

Second, the development of LED semiconductor technology
With the development of science and technology, LED semiconductor technology has been widely used in all walks of life. Its application fields mainly focus on signal indication, intelligent display, automobile lamps, landscape lighting and special lighting, etc. The following are the latest developments of LED technology:
1. Nanocrystalline LED: Bohr research institute studies nanocrystalline LED. The core of the nanowire is Gan material, with a length of about 2 microns and a diameter of about 10 ~ 500 nanometers. The light in the diode is determined by the mechanical tension between the two materials, and the nanowires can use less energy to provide greater brightness and energy efficiency.
2, quantum dots LED: quantum dots (QD) using nanotechnology, QD particles, generally between 2 ~ 12 nm nm, nuclear, semiconductor quantum dot light by emitting shell, organic ligand, such as light-emitting nuclear cdse particles of cadmium selenide (QD), its advantage is that can launch infrared and visible light, light stability, internal quantum efficiency can reach 90%, combined with the LED color is rich, is bright warm white.
3. LED close to sunlight: it has been studied that the surface plate of nanoparticles is used to scatter the white LED light source to get the light close to the sunlight. By using the principle of Rayleigh scattering, the white LED array can be diffused into the "blue sky" effect, or the tiny yellow spots can simulate the sunlight.
