| LED lamps |
There's no secret the energy saving technologies’ topicality in every area of people’s activities is very high nowadays. That concerns the lighting devices as well. The ordinary bulb is more then 100 years old and can’t satisfy the present requirements and compete the modern energy saving lamps. It’s noted fact, that European Union uses new low to gradually decrease the ordinary bulbs’ sales. They’re going to completely forbid the bulbs distribution by the end of 2012. There’s a similar process in Ukraine as well, where the government is considering plans of termination the bulbs using and replacing them by energy saving (including LED) lamps. The LED lamps are of the biggest interest in that case and have very big perspectives. The LED lamp basis is a light-emitting diode – the semiconductor device, which converts electricity to a light flux of different spectrum and intensity. This leads to the following LED lamps’ advantages:
- Long operation life (up to 100000 hours) - High efficiency and economy, minimum of power consumption - Wide range of feeding voltage, insensibility the voltage drops - Standard range of bases (E-14, E-27, E-40, etc.) - High color saturation and purity without heliofilter using, high color rendering index - Instantaneous switching, no time for worming up is needed - Dimmer brightness control applicable - Minimum heat emission - Vibration and shock resistant case - No harmful substances and admixtures, harmlessness for environment, no utilization problems - Absolutely harmless for eyes, no ultraviolet and infrared side emission, no blinking
