Abstract

The invention discloses a light-emitting diode (LED) lamp with a rotary radiating function. The LED lamp comprises a lamp body and an LED light source, wherein the LED light source is arranged on a panel of the lamp body. The LED lamp is characterized by also comprising a radiating substrate and a rotary light guide plate, wherein the radiating substrate for radiating is arranged below the panel of the lamp body; and the upper part of the panel of the lamp body outside the LED light source is connected with the rotary light guide plate capable of rotating. The invention solves the problems that the LED lamp does not have a radiating structure, and is poor in radiating effect, quickly aged, and low in use stability, and the illuminating angle cannot be regulated in the prior art, and provides an LED lamp with a rotary radiating function, which has good radiating effect and long service life and of which the illuminating angle can be adjusted as required to make the illumination of light more concentrated.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a rotating heat dissipation function. Background technique [0002] Traditional lighting mostly uses high-pressure sodium lamps, but with the development of technology, LED lamps have been widely used in various lighting fields due to their advantages such as high luminous efficiency, low power consumption, no need for high voltage, and high safety. When lighting large areas (such as headlights, street lights, tunnel lights, square lighting, factory lighting, park lights, etc.), the power of LED lights is relatively high at this time, and the life of LED light sources is closely related to the operating temperature of nodes. During the working process of LED lamps, only 15% to 25% of the electrical energy is converted into light energy, and the rest of the electrical energy is almost converted into heat energy, which increases the temperature of the LED lamp, and its reliability wi...
