High-efficiency light-emitting diode (LED) lamp

Abstract

The invention relates to a high-efficiency light-emitting diode (LED) lamp. A lamp board and a light guiding pillar are respectively arranged in a lamp holder, a lamp shade is arranged at the upper end of the lamp holder, and a connector electrically connected with the lamp board is fixedly arranged at the bottom end of the lamp holder. The lamp holder is formed by sintering fine ceramics and alumina ceramics at high temperature and can have ideal radiating characteristics due to fine pores. The light guiding pillar is formed by high borosilicate glass and has high transparency, the bottom end of the light guiding pillar corresponds to a light-emitting diode on the lamp board, and a reflecting casing is arranged at the top end of the light guiding pillar; and the reflecting casing has a conical reflecting mirror surface and corresponds to the light-emitting diode on the light guiding pillar. By means of the structure, the light-emitting diode generates light rays and ejects the light rays on the whole light guiding pillar, and the light rays are simultaneously reflected on the reflecting mirror surface, so that the whole circumference surface of the light guiding pillar shines, and light-emitting efficiency is remarkably improved.

Description

technical field [0001] The invention relates to an LED lamp, especially an LED lamp with ideal heat dissipation characteristics and luminous efficiency. Background technique [0002] Due to the low power consumption and long working life of light-emitting diodes, light-emitting diodes of various colors have come out one after another in recent years, especially after white light-emitting diodes are launched, light-emitting diodes have become the main light source of environmentally friendly lamps. Due to the needs of lighting, high-power and high-brightness light-emitting diodes are applied to lamps, but the problem of heat dissipation inevitably arises from the increased power of light-emitting diodes, that is, the lamp itself must provide good heat dissipation measures for the light-emitting diodes. In order to ensure the normal operation of light-emitting diodes, for example, the shells of many LED lamps in the market are composed of many cooling fins, which use the heat-...

Problems solved by technology

Due to the needs of lighting, high-power and high-brightness light-emitting diodes are applied to lamps, but the problem of heat dissipation inevitably arises from the increased power of light-emitting diodes, that is, the lamp itself must provide good heat dissipation measures for the light-emitting diodes. In order to ensure the normal operation of light-emitting diodes, for example, the shells of many LED lamps in the market are composed of many cooling fins, which use the heat-dissipating fins to evaporate the high heat generated by the light-emitting diodes when they are working. Traditional light bulbs are very different, and the structure is bound to be more complicated

[0003] Furthermore, traditional light bulbs can emit light on the entire circumference of a spherical lampshade, but the light-emitting diodes used in LED lamps have certain restrictions on the angle of light emission, and it is bound to be unable to provide lighting functions that emit light on the entire circumference. The solution may be More light-emitting diodes are directed at different angles to provide wide-angle lighting, but this will inevitably increase the complexity and manufacturing cost of LED lamps

[0004] In addition, as far as the power supply is concerned, the existing LED lamps use a transformer to convert AC into DC and then supply it to the LED. improve
