Shifting to LED lighting is a small but fast-growing trend that is redefining the century-old conception of lighting. Replacing energy-wasting disposable bulbs with efficient fixtures that are often semi-permanent, like those used in plumbing.
What are LED’s?
LED’s are essentially small “light bulbs” which do not contain a filament that can burn out or get extremely hot, and instead use a diode. A diode is the simplest form of a semiconductor, which is able to convert electrical current into light. When turned on, current flows from the anode side to the cathode side, passing over holes within the diode, where it re-combines and releases energy in the form of photons. This effect is known as electroluminescence, and the color of the light emitted is determined by the bandgap and materials between the anode and cathode. Unlike traditional bulbs, colored LED’s produce very narrow bandwidths of light measured in nano-meters, abbreviated nm. For example, a LED rated at 660nm peak output, emits trace amounts of light at 640nm and 680nm (bottom photo), focusing the vast majority of its light directly at 660nm.
Standard HID light bulbs emit a broad spectrum of light from 400-700nm, which is very inefficient for plant growth. This kind of light is labeled “white light”, as it appears white in color to the human eye. All in all, about 30% of the light emitted by these broad-spectrum “white” sources, is converted by plants via photosynthesis, while the rest is wasted. It is for this reason that microled lights have been developed, as they are able to tailor their spectral outputs to the wavelength used most efficiently for photosynthesis. This allows nearly 100% of the light created to be used by plants, which is why you need less power to achieve the same results with LED as you are accustomed to with HID.
LED bulb is clear that as long as the cost of LED lights with LED technology continues to improve adversely affected. Energy-saving LED bulb lights and incandescent bulbs will certainly be replaced. At present, more and more attention to lighting energy conservation and environmental protection issues, has been vigorously promoting the use of LED bulbs in. LED bulbs are available in both screw type and pin type bases in a variety of brightnesses and wattages.
LED Indoor & Outdoor Lighting
Residential lighting gives colors of life to your house and its surroundings. The real beauty of home lighting is that it can be a continuous evolution in and of your home whether it is designed at the start or thought about it later during a redesign project. LEDs are more than twice as efficient as CFLs – compact fluorescent lights — currently the standard for greener lighting. And the longer life saves the replacement time, which can be more of savings than the bulbs or energy itself.
Unlike compact fluorescents, LEDs turn on quickly and are compatible with dimmer switches. Fluorescent bulbs also contain mercury, which requires special disposal, and LED lights contain no toxic elements, are so small, and last so long that disposal is not much of an issue.
