LED candle lamp dissipating heat by utilizing bottom-up free mobility of air

Abstract

The invention provides an LED candle lamp dissipating heat by utilizing bottom-up free mobility of air. The LED candle lamp comprises a lamp cup, LED lamp beads, a heat conducting column, a candle-shaped lampshade and a flexible circuit board. The LED lamp beads are installed on the flexible circuit board. The flexible circuit board is tightly attached to the surface of the heat conducting column in a surrounding mode. The candle-shaped lampshade and the lamp cup are fixedly assembled. The LED candle lamp further comprises an upper partition plate and a lower metal partition plate. An upper vent hole is formed in the upper partition plate. A lower vent hole is formed in the lower metal partition plate. The heat conducting column is of a cylindrical structure which is vertically communicated. The upper vent hole in the upper partition plate and an upper port in the heat conducting column are assembled in a matched mode. The lower vent hole in the lower metal partition plate and a lower port in the heat conducting column are assembled in a matched mode. A plurality of air inlet holes are formed in the lamp cup. A plurality of air outlet holes are formed in the candle-shaped lampshade. A ventilation and heat dissipation system with air flowing from bottom to top is composed of the air inlet holes, the lower vent hole, the heat conducting column, the upper vent hole and the air outlet holes. The LED candle lamp has the advantages that the heat is dissipated during free convection of the air to the exterior of a lamp body, the heat is rapidly dissipated, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an LED candle lamp which uses air to freely flow from bottom to top to dissipate heat. Background technique [0002] Currently available LED candle lamps on the market, the structure of the candle lamp is that the upper part is an LED light source and a candle-like lampshade, and the lower part is a metal shell with thermal conductivity and a built-in power supply for heat dissipation. The traditional heat dissipation method of LED candle lights is that the heat generated by the LED light source is transmitted downwards to the metal shell, and then the heat is released into the air through the metal shell to achieve the heat dissipation effect of the lamps. However, in daily life, LED candle lights are generally used as light sources. It is installed and used vertically upwards, and from the principle of thermodynamics, heat flows from bottom to top, so the heat dissipa...

Problems solved by technology

The traditional heat dissipation method of LED candle lights is that the heat generated by the LED light source is transmitted downwards to the metal shell, and then the heat is released into the air through the metal shell to achieve the heat dissipation effect of the lamps. However, in daily life, LED candle lights are generally used as light sources. It is installed vertically upwards, and from the principle of thermodynamics, heat flows from bottom to top, so the heat dissipation effect of traditional LED candle lamps cannot reach the ideal state

At the same time, in order to avoid the risk of electric shock caused by the metal shell of the traditional LED candle lamp, this kind of LED candle lamp must use the drive power of the isolated circuit, and the isolated drive power will also generate a lot of heat when it is working, resulting in a higher temperature of the shell. At the same time, the work efficiency of LED candle lamps using isolated drive power is not high, and electromagnetic interference is also difficult to deal with
