Abstract

The invention discloses a light-emitting diode (LED) bulb lamp. A radiating casing in the LED bulb lamp comprises a hollow annular fin group, a first port and a second port, wherein the hollow annular fin group is formed by at least three fins evenly distributed on a circumference at intervals, and the first port and the second port extend out from two ends of the radiating casing. The first port and the second port are respectively combined with a first annular guide rail in a lamp holder installation base and a second annular guide rail in a lamp shade installation base in a sleeved mode through a first ball and a second ball, so that the radiating casing can rotate along the lamp holder installation base and the lamp shade installation base. During working of the LED bulb lamp, air in the radiating casing is heated by an LED chip, the hot air rises up, a radiating casing group can be pushed to rotate along the first annular guide rail and the second annular guide rail by utilizing the air heat convection theory, air flowing is accelerated, and natural radiating is combined with air cooling forced radiating, so that the radiating effect is enhanced. Gaps are reserved among adjacent fins of the annular fin group, so that the radiating casing is of an opened structure, and the heat can be radiated conveniently.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED bulb lamp. Background technique [0002] LED (full name in English: Light Emitting Diode, translated as: Light Emitting Diode) is a solid semiconductor device that can directly convert electrical energy into light energy. As a light source, LED has the characteristics of short lighting delay, wide color temperature range, high luminous intensity, high luminous efficiency, and good shock resistance. [0003] The LED lamp with LED as the light source has a domestic standard life span of 60,000 to 100,000 hours, which is much higher than the 8,000 hours of ordinary energy-saving lamps. Therefore, LED lamps, especially high-power LED lamps, have begun to appear in various occasions as substitutes for incandescent lamps and energy-saving lamps. [0004] When the LED is on, except for the electricity consumed as visible light, the other electricity is converte...
