Recently, when illuminating the facades of buildings, tunnels and protected areas, to illuminate pools and fountains, you can increasingly find such lighting devices as LED spotlights. Why are they gaining so much popularity? What are their advantages and disadvantages? In the article we will try to answer these questions.
LED floodlights are able to work in all weather conditions: in heat and frost, in snow and rain; they are resistant to mechanical damage: shocks and falls; able to work for many years with minimal power consumption. In the modern world, the main item of expenditure is the cost of electricity. Due to the low consumption of electric current, LED spotlights have gained immense popularity: now there is no need to deny yourself lighting a personal plot, warehouse, industrial areas. You can realize any bold solutions for lighting your home, garage, shop windows or shop signs.
Let's consideradvantages and disadvantages of spotlights with LED lamps.
The advantages of such products include:
- low power consumption, 10 times lower than incandescent lamps, three times lower than energy-saving fluorescent lamps;
- incredibly long service life - 11 years of continuous operation;
- no mercury, which makes these lamps environmentally friendly.
Disadvantages include:
- high price;
- the manufacturer claims a service life of 11 years, but the warranty period does not exceed five years - this is due to the aging (degradation) of the LEDs, first they lose their sharpness, and then go out altogether;
- to increase the service life, it is necessary to use cooling systems and power supplies that will protect the spotlight from voltage surges, which greatly increases the cost of such devices.
And what are led spotlights? These fixtures are lighting equipment, consist of a voltage converter, a reflector, a heavy-duty LED lamp, an external heat sink that provides heat dissipation.
LED spotlights are classified according to the following criteria:
- according to the level of protection there are: IP 65 - outdoor use, IP 44 - indoor use, IP 68 - underwater, IP 67 - ground;
- by purpose: specialized (for the army - search, signal; concert, laser and others) and general use;
- by color (there are blue,red, yellow, green, white);
- by configuration (square, rectangular, linear, round);
- Voltage (12V, 24V, 220V).
There is a modification - an LED spotlight with a sensor. They belong to short-range searchlights, used to illuminate specified areas. They are interesting because they do not burn constantly, but turn on only when people, animals, objects appear in their area of action and go out after a certain period of time. This is due to the built-in sensor that responds to movement. This mode of operation provides additional energy savings and increases the life of the device.
