With all the introduction of LEED certification and also the general trend towards green technology and home efficiency, lighting technology has become a progressively critical component of “going green”. While these make nice catch phrases, hopefully to dive deeper in to the subject and give a solid knowledge base for all those seeking a better comprehension of energy efficiency because it relates to lighting technology.
incandescent lightIncandescent: This bulb includes glass bulb enclosure containing a wire filament. Electric current passes throughout the filament, which then heats up and radiates the vitality as visible light. Incandescent has been the most prevalent kind of bulb for more than a century and has long held the typical for color rendering and consumers’ expectations of methods LED Lamps should operate, but is slowly being phased out with the Energy Independence and Security Act of 2007 for its inefficiency. Most incandescent bulbs will likely be from production at the end of 2015. Incandescent lamps also emit a tremendous part of their energy as ultraviolet and infrared radiation, which can be invisible on the eye but potentially damaging to precious or light-sensitive objects.

halogen lightHalogen: An even more advanced kind of incandescent, the halogen bulb uses halogen gas as well as a tungsten filament to improve light output and efficiency of the incandescent bulb. They are recognized for slightly higher efficiency than typical incandescents, along with a brighter, whiter light than is supplied through the original incandescent bulb. Halogen lamps are generally the first choice for homeowners, since they are better suited for directional aiming of fixtures and supply more focused beam patterns when found in reflector-lamp formats. Halogen lamps tend to be applied to movie sets as well as in auto headlights, and so are typically seen in spotlights and floodlights. General Electric was the first one to patent and then sell on this bulb in 1959. The biggest drawback? The exceptionally short lamp life, much like that relating to incandescent lamps, makes these costly to maintain, specially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t utilize a filament to create light; instead they normally use a glass tube coated with phosphors that contains a tiny 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 produce visible light. Initially the bulb takes a little longer to turn on, but when on they utilize about 70% less energy compared to the LED Bulbs. The hue quality of compact fluorescent lamps is generally subpar compared to halogen and incandescent, as well as the dimming performance is not 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 as much as 10,000 hourrs and much more.

Metal halide: High intensity discharge technology is surely an arc lamp technology which had been created in the 1960’s. Inside a glass envelope loaded with argon gas is definitely an arc tube manufactured from either quartz or ceramic and contains mercury and metal halide salts. The mix of gas, mercury and halide salts in the tube generates a powerful bright white light once heated through the electric arc contained inside. Metal halide lamps are really efficient, have excellent lamp life (some over 20,000 hours), and are designed for putting out a huge amount of light, so they’re typically utilized for high ceiling applications where plenty of light is required, stadium lights, roadway lighting, and parking lot and also other exterior lighting applications. The main problem with metal halide lamps involves switching and dimming. Most metal halide lamps cannot switch on while “hot”, meaning when the power quickly scans the blogosphere, a restrike time period of 15 to twenty or so minutes is needed to ensure that the lamps to cool off enough to transform back on again. Furthermore, these are extremely hard to dim. So although they are great at putting out a lot of light, hopefully that’s what you wish – as there is just one single setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, are a solid state technology that have no filament, glass envelope, gas, or mercury. LEDs produce light with the movement of electrons that is a result of applying an electrical voltage difference across a semiconductor material. Each semiconductor material produces light of the specific wavelength range, so alone, LEDs are not competent at producing white light. Comparable to other technologies, white light might be generated with a phosphor coating, even though the excitation energy is usually given by a blue light LED. As they don’t get hot in the traditional sense, LEDs do generate heat, it’s not within the light path: it will come out the opposite end, and proper dissipation on this heat through careful thermal management is crucial in determining the lifespan of the light source. A hot LED will fail, but a properly-designed LED source of light might be rated for a 50,000 hr life and longer (in lab conditions some LEDs have been thought to last over 100,000 hrs). This surpasses the 48dexkpky of the incandescent bulb by tens of thousands of hours. While LED home lights are still not the most prevalent kind of residential lighting, LED Tubes have been employed in things for many years like cellular phones, Christmas lights, traffic lights and televisions. LED home lighting is 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.
