Abstract

The invention discloses a radiating structure of a heat accumulating light emitting diode (LED) lamp. The radiating structure comprises a lampshade, an LED chip, a radiating pedestal, a heat accumulating box, a lamp body, a screw mouth and a lamp electrode tip, wherein the LED chip is tightly attached to the radiating pedestal; the lamp body is fixedly connected with the radiating pedestal by the heat accumulating box; a control circuit is arranged in the lamp body; and the control circuit is connected with the LED chip by using a lead. The heat accumulating box is sealed, a heat accumulating material is put into the heat accumulating box, and the heat accumulating material is sodium thiosulfate pentahydrate, the melting point of which is about 50 DEG C. The radiating structure has the advantages that: a fan for radiating is not used, and a moving component is not installed; the LED lamp is reliable in use and energy-saving, and has no noise; heat generated when the LED chip works is absorbed by using melting latent heat of the heat accumulating material, so that the temperature of the LED chip is controlled, and the LED chip is effectively prevented from being impacted by heat; and the radiating structure is easy to make and install and convenient to produce.

Description

technical field [0001] The invention relates to a heat dissipation structure, in particular to a heat dissipation structure of a heat-storing LED lamp. Background technique [0002] Existing LED lighting lamps generate a lot of heat during work. If the heat is not dissipated to the outside in time, the temperature of the LED chip will rise, and the chip will often fail when working at high temperature. In order to increase the reliability of the work, a radiator should be designed to dissipate heat from the chip. Existing heat sinks for LED lamps generally use the surface of the lamp shell to dissipate heat. When the LED lighting lamp works for a long time, the service life of the LED lighting lamp is likely to decrease, or even burn out. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat-storage LED lamp heat dissipation structure with good heat dissipation performance. [0004] Technical scheme of the pre...
