LED Landscape Lighting Development Analysis

Landscape lighting always reminds people of the city's colorful scenery and the clouds of light shining above the lights. LED, the fourth revolution in the history of human lighting LED is a luminous semiconductor component, and it is recognized as one of the most promising high-tech products in the 21st century. It also promotes energy-saving emission reduction and environmental protection while igniting the lighting revolution. Protection makes a significant contribution. With the vigorous promotion of the government and the shift of global industry ladders, the future landscape lighting will be the generation of LED dancing.

Why LED is favored by landscape lighting

(1) LED lighting has a huge energy-saving effect, single LED power is only 0.03-0.06W, and the driving voltage is low (1.5-3.5V), the current is small (15-18mA), in the case of forming an equivalent lighting effect, The power consumption is only one-eighth that of incandescent lamps and half that of fluorescent lamps. It can be seen that the use of LED light sources instead of ordinary lamps and fluorescent lamps is used for landscape lighting with large power consumption. The energy-saving effect is very obvious, and it has a strong market competitiveness. And the life of the LED light source is 100 times that of the incandescent lamp and 20-30 times that of the fluorescent lamp, which eliminates the need for frequent maintenance. With its rich colors and good controllability, the LED light source is excellent for use in urban landscape lighting. . Now, LED is replacing traditional light sources by 50%, which will trigger the fourth revolution in the history of human lighting, greatly improve the living environment of human beings, and ease the increasingly severe global energy crisis.

(2) LED light source structure is lightweight (epoxy resin package), small and exquisite, can adapt to a variety of geometric sizes and different space sizes, is a solid light source, not inflated, there is no gas sealing problem, no glass housing, resistant Impact, vibration resistance, and not easily broken, determine its light intensity and rigidity lower than other electric light source requirements. Moreover, the LED is a cold light source, which has good controllability, fast response time, and can be repeatedly turned on and off without fatigue.

(3) LED light source color is pure, rich, can evolve any color, better than the color metal halide lamp, its unparalleled decorative. The compactness of the LED light source makes it very flexible and can form a variety of points, lines, surfaces, balls and other shapes. According to the purpose of landscape lighting decoration and beautification, the LED light source adopts microcomputer intelligent control technology, and its changes can be made suitable for points, lines, surfaces, balls and other forms, including: flicker (flicker) control, suitable for forming "points, lines" "Graduate (flexible) control, suitable for the formation of "face"; dynamic change (jump) control, suitable for the formation of patterns of vertical and horizontal dynamic changes. The above three kinds of changes can also form the rotation of the ball, in addition to single lamp control and group lamp control.


Of course, LEDs are not without their drawbacks.

(1) The LED is more "precious" and requires supporting solutions such as excellent heat dissipation and constant current drive. If it is used improperly, it is prone to light decay or even "dead light".

(2) The power of a single LED is low, and in order to obtain high power, multiple parallel use is required.

(3) LED color rendering index is low. The color displayed under the LED illumination is not true to the incandescent lamp. This has to be analyzed from the spectral distribution and is a technical problem.
