In fact, in order to improve visibility and viewing, LED landscape lights are more and more widely used. Mainly because LED landscape lights have the following four characteristics:
1. Good luminous uniformity, the emission angle is 100, and the luminous rate is 4050 mm/W.
2. The average life of the light source is 100,000 hours, and there is no serious light attenuation. The luminous attenuation is 10%, and the energy consumption is 24W.
3. The luminous wavelength must be consistent, and the luminous intensity of RGB must be able to change continuously. Red light: 630 nanometers, 650 nanometers, yellow light: 585 nanometers, 593 nanometers, green light: 525 nanometers, 528 nanometers, blue light: 467 nanometers, 473 nanometers
4. It can be programmed and controlled according to the overall requirements of the environment to produce an overall artistic landscape effect.
The lighting principle of energy-saving and environmentally friendly LED landscape lights is different from that of incandescent lamps and gas discharge lamps. The energy conversion efficiency of the LED light source is very high. In theory, it can reach 10% of the energy consumption of incandescent lamps. Compared with fluorescent lamps, LEDs can also achieve 50% energy-saving effects. Compared with incandescent lamps of the same brightness, LEDs with a luminous efficiency of 75mm/W consume about 80% less power and have significant energy-saving effects. This is undoubtedly of great significance to China, where energy is very scarce. LEDs can also be combined with solar cells, which is energy-saving and environmentally friendly. It does not contain toxic and harmful substances (such as mercury), avoiding secondary pollution of mercury overflowing from the ruptured fluorescent tube, and does not interfere with radiation. The LED light source is not only more environmentally friendly and energy-saving, but also has a wider color gamut and higher color saturation. More importantly, the service life of LED lighting sources is as long as 60,000 hours, which can solve the problem of short service life of traditional light bulbs.
Long service life Under normal conditions, the light attenuation of LED landscape lights can be reduced to 70%. The nominal service life is 100,000 hours, which reduces the frequency of replacement and other maintenance tasks.
Pure light color, because the spectrum range of typical LED landscape lights is relatively narrow, not full spectrum like incandescent lamps. Therefore, light-emitting diodes can be randomly and diversely matched and combined, which is particularly suitable for decoration and other aspects. Bright, saturated, and pure, without filters, red, green, and blue elements can be mixed into various colors, which can achieve variable, gradual, and mixed light effects, and the color rendering effect is good. It can realize continuous brightness adjustment, high color purity, dynamic color conversion and digital control.
Moisture-proof and shock-proof. Since the exterior of the LED is mostly protected by epoxy resin, the sealing performance and impact resistance are very good, and it is not easy to damage. Can be applied to underwater lighting.
Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation. Compared with other light sources, LEDs are called "green light sources".
