Abstract
Description
- The invention relates to light sources and more particularly to an LED (light-emitting diode) having a heat removal device for sufficiently dissipating excess heat generated by a high power ("Hi-Power") LED.
- LED lamps have advantages including longer life, less power consumption (i.e., more energy-efficient), and no special ballasts being required. Thus, LED based light sources have gradually replace conventional incandescent lamps and fluorescent lamps as an ideal light source.
- One type of LED lamp has a Hi-Power LED as light source. However, excess heat can be generated by the Hi-Power LED. Hence, such LED lamps are limited in applications (e.g., in indoor environment). Hence, a need has arisen for an improved LED lamp having a heat removal device for dissipating excess heat generated by the Hi-Power LED so that the LED lamp can find applications in indoor environment.
- There have been numerous suggestions in prior patents for LED based light sources. For example,
U.S. Pat. No. 5,688,042 discloses an LED lamp andU.S. Pat. No. 7,086,767 discloses an LED bulb. - It is therefore one object of the invention to provide an LED bulb including a metal heat removal device mounted between a bulb and a housing, and a Hi-Power LED being in good thermal contact with the heat removal device such that excess heat generated by the Hi-Power LED can be sufficiently dissipated.
- In one aspect of the invention the heat removal device comprises an outer, inverted, truncated cone and a top mounting member secured to the bulb, the mounting member being integrally formed with the cone by die casting.
- In another aspect of the invention the heat removal device comprises an outer, inverted, truncated cone and a top mounting member secured to the bulb, the mounting member being formed separately prior to assembling with the cone.
- In yet another aspect of the invention the cone comprises a plurality of longitudinal heat radiating grooves so as to provide a large heat radiating surface.
- In a further aspect of the invention the heat radiating grooves have openings so as to provide a large heat radiating surface and space.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
