LED Technical


What is an LED? LED is the common abbreviation for a Light Emitting Diode. As indicated by its name, the LED is a diode that emits light. Because LEDs are illuminated by the movement of electrons in semiconductor material, they last for an amazing amount of time, give off virtually no heat and don' t contain any hazardous substances. Highly efficient and environmentally friendly, LED street lighting  are widely used to light homes, offices, shops, hospitals and hotels as well as outdoor spaces.
What are the benefits of LED solutions? 
• Big energy savings – over 60% in comparison to traditional street lighting 
• Good colour rendering, making colours more natural 
• Long life – up to 100,000 hours, resulting in less maintenance
 • Uniform, high quality white light. LED lighting provides better facial recognition for security and CCTV cameras and therefore helps to make areas safer. 
• LEDs can be dimmed when light is not needed, resulting in additional energy savings. LEDs can also be connected to sensors and controls and networked so that they can be controlled remotely
Do LED' s contain hazardous chemicals?
No, the street lighting LED' s contain no hazardous chemicals, unlike most fluorescent or High Intensity Discharge (traditional street lighting) lamp sources which contain mercury. In addition, the LED luminaires are RoHS (Restriction of Hazardous Substances) compliant.
Is it true LED lights produce blue light that can disrupt sleep by suppressing the body’s production of melatonin?

LEDs can be made in cool white and warm white light. Adding more red light creates a warmer white light, whereas the addition of blue light produces cool white. When a white light solution replaces traditional discharge street lighting it does usually mean adding more blue. But it is a tiny fraction of the content in natural daylight, and does not have any detrimental effect on people.
