LED Lighting – the Varieties of Offered LED Lighting.

With the introduction of LEED certification and the general trend towards green technology and home efficiency, lighting technologies have become a progressively critical aspect of “going green”. While these make nice catch phrases, hopefully to dive deeper into the subject and provide a solid knowledge base for people seeking a much better idea of energy efficiency mainly because it pertains to lighting technology.

incandescent lightIncandescent: This bulb includes a glass bulb enclosure containing a wire filament. Electric current passes with the filament, which in turn gets hot and radiates the power as visible light. Incandescent is the most common form of bulb more than a hundred years and contains long held the typical for color rendering and consumers’ expectations of methods LED Lamps should operate, but is slowly being eliminated from the Energy Independence and Security Act of 2007 for its inefficiency. Most incandescent bulbs will probably be out from production in the end of 2015. Incandescent lamps also emit a substantial percentage of their energy as ultraviolet and infrared radiation, that happen to be invisible towards the eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A much more advanced form of incandescent, the halogen bulb uses halogen gas along with a tungsten filament to improve light output and efficiency from the incandescent light bulb. They can be recognized for slightly higher efficiency than typical incandescents, and a brighter, whiter light than is provided by the original incandescent bulb. Halogen lamps are usually the 1st selection for homeowners, since they are more appropriate for directional aiming of fixtures and give more focused beam patterns when found in reflector-lamp formats. Halogen lamps are often applied to movie sets as well as in auto headlights, and are typically present in spotlights and floodlights. General Electric was the first to patent then sell this bulb in 1959. The most significant drawback? The exceptionally short lamp life, just like that from incandescent lamps, makes these costly to maintain, specially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to make light; instead they utilize a glass tube coated with phosphors which contains a modest amount of argon and mercury vapor and electrodes at one end. When electricity is used, the electrodes generate an invisible ultraviolet light that then excites the fluorescent coating on the inside of the tube to generate visible light. Initially the bulb has a little longer to transform on, but when on they use about 70% less energy compared to the LED Candle Lights. The colour quality of compact fluorescent lamps is often subpar compared to halogen and incandescent, as well as the dimming performance will not be as smooth either, rarely getting down to the minimum light levels that incandescent and halogen can. However, the lamp every day life is significantly longer – lasting around 10,000 hourrs and more. Learn more about replacing compact fluorescent lighting and our Color Curve Dimming products.

Metal halide: Intense discharge technology is an arc lamp technology which was created in the 1960’s. In a glass envelope filled up with argon gas is an arc tube created from either quartz or ceramic and features mercury and metal halide salts. The mix of gas, mercury and halide salts inside the tube generates an intense bright white light once heated through the electric arc contained inside. Metal halide lamps are incredibly efficient, have excellent lamp life (some over 20,000 hours), and are designed for putting out a huge volume of light, so they’re typically employed for high ceiling applications where a lot of light is needed, stadium lights, roadway lighting, and parking lot as well as other exterior lighting applications. The principle problem with metal halide lamps involves switching and dimming. Most metal halide lamps cannot start up while “hot”, meaning in the event the power goes out, a restrike period of 15 to 20 mins is essential to ensure the lamps to cool off enough to make back on again. Furthermore, they are extremely difficult to dim. So while they are great at putting out plenty of light, hopefully that’s what you need – because there is just one single setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, certainly are a solid state technology which may have no filament, glass envelope, gas, or mercury. LEDs produce light through the movement of electrons that results from applying an electrical voltage difference across a semiconductor material. Each semiconductor material produces light of your specific wavelength range, so on their own, LEDs are certainly not effective at producing white light. Comparable to other technologies, white light may be generated by using a phosphor coating, while the excitation energy is usually given by a blue light LED. Whilst they don’t get hot in the traditional sense, LEDs do generate heat, it’s hardly in the light path: it comes the opposite end, and proper dissipation of the heat through careful thermal management is essential in determining the lifespan of the light source. A hot LED will fail, but a well-designed LED source of light may be rated for the 50,000 hr life and longer (in lab conditions some LEDs have been believed to last over 100,000 hrs). This surpasses the 48dexkpky of your incandescent bulb by hundreds and hundreds of hours. While LED home lighting is still not the most frequent type of residential lighting, LED Tubes have been employed in things for years like mobile devices, Christmas lights, traffic lights and televisions. LED home lights are also popular because LEDs use 90% less power than incandescent lights, are ecologically friendly, have zero UV emissions or mercury, and they are very durable.
