Incandescent era Rest in Peace. It’s time to move on. Traditional incandescent light bulbs are gone—not banned, but phased out. manufacturers have shifted to more energy-efficient technologies, such as compact fluorescents (CFLs), halogens, and LEDs.
As demand has increased and manufacturing processes have become more streamlined, costs have plummeted. Due to awareness programmes People are inclined towards LED Lighting. We are Volume LED Bulb Supplier deal in economical LED bulbs as well as bulbs with warranty periods. For further details please contact us.
LED Lighting Products
LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.
Incandescent light bulbs are gone—not banned, but phased out. manufacturers have shifted to more energy-efficient technologies, such as compact fluorescents (CFLs), halogens, and LEDs.
As the demand of LED lighting has increased and manufacturing processes have become more streamlined, costs have plummeted.
Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot or is said to incandesce. As a result, incandescent bulbs release 90% of their energy as heat.
In a CFL, an electric current flows between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb.
LED Lighting The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or CFL. This is because LEDs typically do not “burn out” or fail. Instead, they experience lumen depreciation, where the amount of light produced decreases and light color appearance can shift over time. Instead of basing the useful life of an LED product on the time it takes for 50% of a large group of lamps to burn out (as is the case with traditional sources), LED product “lifetime” is set based on a prediction of when the light output decreases 30 percent.
LEDs and Heat
Because LED lighting systems don’t radiate heat the way an incandescent or halogen light bulb does, the heat produced from the power going into the product must be drawn away from the LEDs. This is usually done with a heat sink, which is a passive device that absorbs the heat produced and dissipates it into the surrounding environment. This keeps LEDs from overheating and burning out. Thermal management is probably the single most important factor in the successful performance of an LED product over its lifetime because the higher the temperature at which the LEDs are operated, the more quickly the light will degrade, and the shorter the useful life will be.
After less than a year of use, a poorly designed LED product can flicker, shift in color, look dim, offer uneven light, or continue to use power when turned off, among other problems.
LED products use a variety of unique heat sink designs and configurations to manage heat, so they may look very different from each other. Regardless of the heat sink design, all LED products that have earned the ENERGY STAR have been tested to ensure that they properly manage the heat so that the light output is properly maintained through the end of its rated life.
