LED spotlights are used as the main light sources and as decorative lighting. Such devices can be used for lighting architectural design. By what criteria an LED spotlight is chosen - in this article.
Color and power
There are two types of these devices:
- Single color. Such a spotlight cannot change the color of the glow. Models with white light are suitable for lighting a protected area and video surveillance. They provide accurate color reproduction. Devices of other colors can be used for decorative purposes. For example, to illuminate the walls of buildings, trees in a city park.
- Full color. RGB spotlights are used for lighting design, stage decoration during the show. They can be equipped with an infrared or radio remote control to select the color of the glow. They can also be connected to controllers and microprocessors for automatic control.
The power of the device determines the strength of the light flux it creates. Industrial models have a glow brightness of up to 72 thousand lm. At the same time, they are powered by an alternating voltage of 220 V and consume up to 500 W.
Entry-level models with a power of 5-6 W are connected to a 12 V source. They use a constant voltage for operation.
Performance and maintainability
Outdoor models are equipped with a waterproof housing according to IP67 and IP68 standards. There are spotlights that can be installed in fountains, pools. They withstand immersion in water. There are also models for installation in the ground.
Repairability is determined by the possibility of replacing the LED module. In professional models, it is designed for a long service life - up to 50 thousand hours. After that the LED matrix for the spotlight is replaced with a new one. This allows you to restore the device and extend its service life.
Mounting method
LED spotlights can be installed in the following ways:
- To be fixed on the wall or under the roof visor. The device may have a swivel arm. This allows you to choose the direction of the light after installation. For example, to illuminate the territory or illuminate the facade.
- Installed on the ground. Such devices can be used as portable. For example, for lighting a construction site, carrying out installation or emergency work at the facility.
- Installed into the ground. This type of device includes some models of architectural lamps. They are used for landscape design.
Options
- With motion sensor. Models with a motion sensor can automatically turn on when a person or car is detected in the protected area. They can be installed on commercial buildings and on the territory of private homes.
- Solar-powered and battery-powered. The use of such spotlights allows you to save electricity. During the day, the battery is charged by the sun. In the dark, the device turns on and works until the battery is completely discharged. In combination with a motion sensor, you can ensure its operation throughout the night.
- With a lens. Such spotlights can create a directional narrow beam of light. They can be used to illuminate advertising structures. Lens devices are also used in the lighting design of fountains, aquariums.
