LED comprehensive analysis of the history of human lighting

"Landscape lighting", always let people think of the can't help city and colorful, bright lights above reflects the color light clouds. LED, lighting the fourth revolution of LED is a semiconductor light emitting element, is recognized as one of the high-tech products in twenty-first Century the most promising, in the LED lighting revolution at the same time, but also make a significant contribution to the promotion of energy conservation, environmental protection. With the government's promotion and global industry echelon transfer, the future landscape lighting, will be dancing in the LED generation.

LED, lighting the fourth revolution

LED is a semiconductor light emitting element, is recognized as one of the high-tech products in twenty-first Century the most promising, in the LED lighting revolution at the same time, but also make a significant contribution to the promotion of energy conservation, environmental protection. With the government's promotion and global industry echelon transfer, the future landscape lighting, will be dancing in the LED generation.

LED what is the beauty of landscape lighting, has been favored

(1) LED lighting has a huge role in energy saving, power only LED, only 0.03-0.06W, and low driving voltage (1.5-3.5V), current (15-18mA), formed in the same lighting effect, power consumption of only 1/8 of incandescent lamp, fluorescent lamp 1/2. It can be seen that the use of LED light source instead of ordinary lamps and fluorescent lamps for the huge power consumption of landscape lighting, the energy saving effect is very obvious, with a strong market competitiveness. And LED light source life is 100 times the incandescent lamp, fluorescent lamp 20-30 times, eliminating the pain of frequent maintenance, coupled with its rich color and good controllability, for urban landscape lighting is no better. Now, LED is 50% growth rate to replace the traditional light source, will lead to the history of human lighting in the fourth revolution, greatly improving the living environment of mankind, to ease the increasingly serious global energy crisis.

(2) light source structure of LED (epoxy resin package), small size, can adapt to various geometric sizes and different size of the space, which belongs to the solid light source, not inflated, not gas sealing problem, does not need the glass shell, impact resistance, vibration resistance, not easily broken, determines the lamp it is the strength and stiffness than the other electric light source low requirement. Moreover, LED is a cold light source, good controllability, fast response time, can be repeated frequently bright out, not tired.

(3) LED light source color pure, rich, change any color, color is better than the metal halide lamp, decorative incomparable. LED light source, so that its flexibility is very good, can form a variety of points, lines, surfaces, balls and other shapes. According to the landscape lighting decoration, LED light source through the microcomputer intelligent control technology, the changes can be made for point, line and plane, ball and other forms, including: flicker (flashing) control, suitable for the formation of "point line"; gradient (flexible) control, suitable for the formation of "face"; variable (jump) control, suitable for forming a pattern of vertical and horizontal dynamic change. The above three kinds of changes can also form the rotation of the ball, in addition to a single lamp control and group lamp control.

Of course, LED is not without drawbacks.

(1) LED is "delicate", supporting the need for excellent heat dissipation, constant current drive solutions such as support, improper use, it is prone to decay even "dead lights" phenomenon.

(2) single LED low power, in order to obtain high power, the need for multiple parallel use.

(3) LED color index low. In the LED display of the color of the lamp is not real, it is from the spectral distribution analysis, is a technical problem.

LED landscape lighting needs of engineers and designers together into eye stone

While LED, also in landscape lighting function is obvious, but the landscape lighting is not a simple technical parameters, the new carrier as the city was appreciated and promoted, landscape lighting must be the perfect combination of art and technology, are indispensable.

Which based on technology, art and technique support, and art is perfect in technology based on sound extension, like a strong plant, a beautiful flower.

In LED landscape lighting design and installation, engineers and designers must pay attention to the following:

(1) the goal is to make the landscape lighting landscape lighting and landscape coordination, due to the specific scene, the architectural features to the system to a new level, beautify the environment. At the same time, we should pay attention to humanization and intellectualization. The art of landscape lighting must be endowed with vitality through light and lighting.

(2) LED lamps used in landscape lighting, the design should be flexible, do daytime landscaping, night lighting art. The future of landscape lighting, will jump out of crochet, simple running stereotypes, combining the advantages of LED, to provide high quality products and lighting engineering. For example, the use of LED lamps outline architectural outline, or embedded in the construction of LED lights on the facade, through the combination of light and electricity into a pattern, or with a small LED light to illuminate the building or components of the local facade, etc.. The way through the lighting brightness and position of its body to outline the building outline form or decorate the facade, but should be considered as the illuminated object building and style is suitable for use
