Since their inception they have gotten exponentially better. LED stands for light emitting diode, which produce light approximately 90$ more efficiently than incandescent light bulbs. As an electrical current passes through a microchip, which in turn illuminates the tiny light sources and creates visible light. To aid in their performance, any head that the LEDs produce is absorbed into its heat sink.
LEDs are used for many different lighting applications. From desktop lighting to overhead lighting to vehicle lights and many other variations. Because of their small size they can be used in any number of ways and color combinations. They provide very unique design opportunities and have been used extensively in art work around the world. Many match the appearance of traditional bulbs and offers a great opportunity of innovative lightning and energy savings.
LED heat sings are used to absorb heat produced by LED and released it into the environment around it. This keeps the lights from burning out and overheating. It is said that thermal management is the single most important aspect in a long term LED. The higher it burns the shorter its life will be. LED products have a wide range or different kind of head sinks. Different designs and layouts in order to better manage the heat depending on the type and number of LEDs that are being used. Regardless of whichever heat sink design is applied, all products that are Energy Star tested have shown to properly manage their heat so that the LEDs will have the longest life cycle possible.
As directional light sources, LEDs emit light in a specific direction, unlike traditional bulbs which release light and heat in all directions. That means that LEDs can be used to point light in one certain area, allowing for a more fine tuned control option. They come in many different colors, typically amber, red, green, blue, and yellow. Colored lights are typical used as signal lights and indicator lights, lights for buttons as well as for festive events. With CFL bulbs, the current flows between electrodes at each end of a gas filled tube. This creats UV light and heat which is turned into visible light when it strikes a phosphor coating on the inside of the bulb. Incandescent bulbs produce light using electricity that heats a metal filament until it becomes so hot it goes white. Because of this heat, they release 90% of their energy that way.
With ENERGY STAR certified LED lighting, you know that the bulbs you are getting have been subjected to very rigorous and specific testing requirements. Color quality, light output, and compliance with more than 20 other requirements means that these LED bulbs will give you a good run for your money. So move from the car seat to the front seat, replace those ancient bulbs with LEDs and you wont have to worry about buying new ones for years to come.…
