LED or semiconductor are the light sources of the present and the future.
LED lamps or LED bulbs are created based on light-emitting diodes (LED). They have a long life and complete electrical efficiency, thanks to its very high light output, which is several times higher than that of incandescent lamps, and significantly higher than most fluorescent lamps.
LED bulb achieved after switching full brightness in milliseconds, without requiring warm-up time, similar to incandescent lamps. Fluorescent lamps do not have this property. If you combine properly cool white and warm white LED Lamps will completely mimic the spectrum of sunlight.
Most LED Lamps today are directly compatible with the socket of the lamp filament or that of fluorescent lamps.
Socket is called the base of the bulb. It is inserted into a socket and provides both electrical connection and mounting it in the luminaire.
When replacing standard fluorescent tubes with LED tubes must remove the choke, the starter and any electronics. LED tube is connected directly to the mains.
The packaging of each LED lamp purchased from 2R Bulgaria is specified light output in lumens, power consumption in watts, in kelvins is a color temperature or brief description – as “warm white” referred to are more hours of life equivalent power of incandescent lamp. How to write on the packaging of lamps?
1. If we divide these lumens per watts bulb will get its effectiveness.
Example: On incandescent bulb 100 W correspond 1300-1530 lumens bulb 75 W – 920-1060 lumens, 60 W – 700-810 lumens, 40 W – 410-470 lumens and 25 W – 220-250 lumens.
2. The life of the lamp is measured in hours.
Example: Conventional lamps have about 1000 h. LED lamps have a life of over 15,000 h. Energy efficient lamps pritezhavatsashto long life, which, however, depends on the frequency of inclusion and exclusion. In frequent commutations resource sharply reduced.
3. The color of the light emitted corresponds to the color temperature.
Example: Ordinary light emits only warm white light. In LED lamps the color temperature ranges from warm white, matching the 2700 K cool white – 5500-6500 K or neutral – 4000 K, which is closest to the sun. The greatest efficiency is obtained with cold white light.
4. Number of inclusions and exclusions.
Example: The number of inclusions and exclusions is especially important for energy-saving bulbs. LED lamps have no problem with frequent commutations.
5. How long it takes to reach maximum brightness or how fast heat lamp.
Example: Energy saving lamps heat up relatively slower than usual and LED lamps.
6. Ability to regulate and control the light output by dimiruemost lamp.
Example: If the lamp is dimmable, it can be used in lighting system with adjustable lighting.
7. The operating temperature indicates the sensitivity to changes in ambient temperature and humidity.
Example: If a lamp is used for outdoor lighting or higher as altitude places in the winter light output may be reduced at low temperatures.
8. The external dimensions orient us when you need to put a lamp in a specified location.
Example: LED lamps are the most compact of all.
