Outdoor lighting is a kind of lighting used outdoors. The selection of this lighting should fully consider factors such as outdoor environmental conditions and whether it consumes power. LED lights are energy-saving and environmentally friendly, and are often used for landscape lighting. So what are the advantages of LED lights? Let's find out together.
1. Can adapt to outdoor environment, reasonable and safe
When it comes to landscape lighting, LEDs are ideal due to their high color rendering index (CRI) and numerous color temperature options.
Advances in plastic technology and optics and integration with LEDs have paved the way for the ideal combination of optoelectronics. Another benefit of LEDs is that they don't use any filament and are inherently stronger. Also, LEDs are less fragile, and pouring water repellents such as silicon or epoxy over the light source is simple, reasonable, and safe.
Since the light source of LEDs is small, it is very simple to produce efficient luminaires in a compressed size. For example, it is quite possible to create a fountain light to cover the entire fountain, as long as the light sources are separate, small and connected in parallel.
The main function of landscape lighting is safety and decoration. LEDs are considered a bright form of light that can achieve 170-180 lumens per watt and provide reliable light. In addition to this feature, LEDs are less likely to explode or burn out at the light source in the event of overheating conditions or short circuits.
2. Environmentally friendly
LEDs do not emit any infrared or ultraviolet radiation and are completely mercury free. In addition, these lamps are ROHS compliant, which means that the LEDs do not contain any hazardous substances such as cadmium, mercury, etc. In contrast, metal halide lamps contain high levels of cadmium and also emit ultraviolet light while fluorescent lamps have mercury. Since landscape lights are installed near bodies of water or trees in close proximity to nature, LEDs are preferred.
3. Low maintenance cost
The presence of a light source in a backyard light is very important because the location of backyard lights is often in vulnerable areas. For example, underwater lights in swimming pools are difficult to replace because the pool has to be emptied if the lights are to be replaced. Another example is floodlights, which, in the event of a problem, require a crane to restore. In most cases, the cost of replacing the light is much higher than the cost of the light.
4. Low voltage operation
The LEDs function at less than 4VDC, to make them run on 220V we usually use a switching power supply, step down the voltage, thus converting AC to DC. If it is any light that is in direct contact with water, it is recommended to run it at a lower voltage to avoid disasters when the current flows.
When it comes to traditional light sources, we need to use a specific inverter circuit to increase the voltage and convert it to AC. This reduces the safety and longevity of the luminaire while increasing the cost of the luminaire. Also LEDs are a safer option, operate at low voltages and are very safe to operate.
