Description

    BACKGROUND OF THE INVENTION (a) Field of the Invention
  • The present invention relates to a LED bulb, especially to a remote-controlled LED bulb.
    • (b) Description of the Prior Art
  • Compared to conventional lighting such as incandescent lamps, tungsten halogen Illuminator, fluorescence lights, the LED lighting technology has following advantages:
  • 1. Low energy requirement: the LED light source, compared to the traditional light source with the same luminous efficiency, can save over 80 % energy consumption. For example, lights on a 2000-meter-long bridge consume only 10 watt of electricity per hour so that several hundred thousands can be saved per year.
  • 2. Reduced maintenance cost: LEDs do not require any special equipment or drivers, to deal with various environments. And there is no need to replace the light source frequently, the maintenance costs and replacement expenses are reduced dramatically.
  • 3. Longer lifetime: the LED made of semiconductor can convert electric power into light energy. Sealed by epoxy, it can stand high shock and vibration. The LED illuminator normally works for at least twenty thousand hours, even lasts up to hundred thousand hours. Calculation based on 12 hours per day, the light source would be used over 5 years.
  • 4. Higher energy efficiency: the luminous efficiency of the incandescent or halogen sources is 12-24 Im/W and that of the fluorescence lights is 50-120 Im/W. Incandescent or halogen sources, generates most of their light as heat and only produce 10% useful visible light. In order to have a single color, it is necessary to use a color filter to eliminate other colors thus causes the waste of energy. The luminous efficiency of the LED light is 50-200 Im/W with narrow spectrum and single color, no need to user a color filter. The useful visible light only consume 10% energy emitted from the light source.
  • 5. Easy assembling with stableness: even with the temperature extremes, high shock and vibration environment , the LEDs driven by direct current still works stably.
  • 6. Higher safety: the light strength of LED light is adjustable and stable, with lower glare, heat generation, and less ultraviolet light. As a cold light source, users can touch the lamp. No mercury content thus has no harm.
  • The LED illuminator based on new LED technology with features in low power waste, long life span, shock resistance, easiness of control.
