Description

      The present invention relates to an illuminating lamp, and more particularly to an LED lamp that is convenient for a kind of assembly and has a base exchangeable.

      A light emitting diode (LED) applies a positive voltage to the light emitting chip to emit a monochromatic discontinuous beam. Further, by changing the chemical composition inside the light emitting chip, the necessary wavelength of the emitted light can be obtained from the light emitting diode. Since the development of white light LEDs, they have been widely used in lighting devices. The LED has advantages such as high efficiency, small volume, long life, and less damage than conventional light sources. As an example, since high light energy can be generated at a low voltage, 80% or more of electric energy can be saved. Furthermore, LEDs have a service life of 35,000 to 50,000 hours in an appropriate heat dissipation system and application environment, and have a much longer life than conventional light sources. There is no pollution.

      An LED is an illumination light source in which a kind of light source is concentrated and a light emission angle is small. With special design, it can be used as an illumination lamp with the required irradiation angle and range. For example, an LED bulb for home use, a spiral electric input part of a conventional light bulb, or various bulb sockets are screwed or inserted into one end, and positive and negative conductive columns or pin type for taking in electricity and emitting light An electrical input is provided. In order to improve the brightness of the LED bulb, the output power must be increased. However, raising the power generates high heat, and if the heat is not dissipated quickly, not only the brightness is lowered, but the service life of the LED is shortened. Therefore, many commercially available LED bulbs have additional heat dissipating devices for accelerating the heat energy dissipation effect.
