If the current outdoor lighting still uses old-fashioned lighting products, the cost will be higher in terms of power consumption, and there will be great defects in the service life of the products. The production of LED lighting products in the 21st century makes up for this. A huge flaw, here, landscape lamp manufacturers analyze the many advantages of LED in landscape lighting.
In addition to the five advantages of no mercury, energy saving, material saving, no electromagnetic interference to the environment and no harmful radiation, LED light source has many advantages in the field of lighting, especially in landscape lighting. Such as: low-voltage power supply - no high-voltage link, the cost of insulation is much smaller, high reliability; simple accessories - no starter, ballast or ultra-high voltage transformer; simple structure - the greatest advantage of solid light source, Non-inflatable, no glass casing, no gas sealing problem, impact resistance; good controllability - fast response time (on the order of microseconds), can be repeated frequently and repeatedly, basically no inertness, no fatigue; pure color - by The semiconductor PN junction itself produces color, pure, thick; rich colors - three primary colors plus digital technology, can evolve any color; lightweight structure - material saving, cost saving; low requirements on the strength and stiffness of the lamp; Large LED luminaires can be seen as consisting of LED cells, the smallest LED is only on the order of square millimeters or less; flexibility is good - the compactness of the LED light source allows the LED to adapt to decorative lighting requirements of various geometric sizes and different space sizes Such as: points, lines, faces, balls, different forms, and even any artistic sculpture of light.
There are many kinds of light sources that can be used for landscape LED street lighting, and the effects, performance, and cost should be considered when selecting a light source. When comparing the cost of different solutions, not only compare the price of the light source, but also compare the comprehensive economic analysis of the whole life period, because some high-efficiency, long-life light sources, although the price is higher, but the use is reduced, the operation and maintenance costs are low. Economically and technically reasonable.
The traditional light sources used in landscape LED street lighting, such as incandescent lamps and halogen lamps, are bright and bright, and have good color rendering; however, they have low luminous efficiency and relatively short lifetime. Therefore, they are rarely used. At present, the commonly used floodlight LED street light illumination source is a high-pressure discharge lamp, such as a high-pressure mercury lamp, a high-pressure sodium lamp and a metal halide lamp. These light sources have large power and can realize large-area floodlight illumination. However, the common disadvantage of these sources is that it takes a while for the lamp to stabilize after it has been illuminated; moreover, if the lamp is accidentally extinguished, it needs to wait for the lamp to cool sufficiently before it can be restarted. In addition, these lamps are not easy to achieve dynamic effects such as light color change, and if the color filter is used, the color change can be realized, but this will greatly affect the system efficiency. LED street lights will gradually replace high-pressure sodium lamps because of energy-saving needs?
As a fourth-generation solid-state light source, LED street lights are illuminated differently from conventional light sources. It uses the recombination of electrons and holes in a semiconductor PN junction to emit light. The difference in lighting patterns determines the essential difference between LED street lights and traditional light sources, and it also has its own unique characteristics.
Solar LED land lamp uses sunlight as the energy source, charges during the day and uses at night, does not need complex and expensive pipeline laying, can arbitrarily adjust the layout of lamps and lanterns, safe and energy-saving, pollution-free, stable and reliable without manual operation, saving electricity and maintenance. Solar LED street lamp is mainly composed of solar cell module (including bracket), LED lamp holder, control box (with controller, battery) and lamp pole.
