Novel LED candle lamp and LED light source module

Abstract

The invention provides a novel LED candle lamp and an LED light source module. The LED candle lamp comprises a lamp holder, a drive power source, a lamp support, the LED light source module and a lamp shade. The lamp holder is fixedly connected with the lamp support. The drive power source is arranged in an inner cavity of the lamp support. The LED light source module is fixed at the front end of the lamp support. The lamp shade is sleeved on the periphery face of the lamp support and surrounds the LED light source module and the lamp support. The LED light source module comprises a ceramic body, an LED chip and a packaging lens, wherein the electric conduction structure is formed on the ceramic body, the LED chip is installed on the front end portion of the ceramic body, and the packaging lens wraps the LED chip. As heat is dissipated through the lamp shade, the LED candle lamp has the advantages of being simple in structure, large in illumination angle and high in safety. According to the LED light source module, the ceramic body with high thermal conductivity has the functions of mechanically supporting the LED chip, and conducting electricity and heat, and therefore the structure of the LED light source module can be simplified, and the heat-dissipation property of the LED light source module is improved.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to a novel LED candle lamp and an LED light source module. Background technique [0002] Existing LED candle lights usually include an external metal heat sink or ceramic heat sink. For example, the Chinese invention patent application CN201110428623.5 discloses an LED candle light including a metal heat sink. The heat generated is exported to the outside of the LED candle lamp. In such an LED candle lamp, the light emitted from the LED toward the lamp cap is blocked by an external metal radiator, and it is difficult to obtain the same light distribution characteristics as a conventional lighting device. In addition, the external metal radiator is conductive. If there is a leakage defect in the circuit structure of the LED candle lamp, there may be a leakage current on the radiator, which will cause unsafe hazards for users to get an electric shock. However, if the metal radiator is cance...

AI Technical Summary

Problems solved by technology

In such LED candle lamps, the light emitted from the LED toward the lamp cap is blocked by the external metal radiator, making it difficult to obtain the same light distribution characteristics as traditional lighting devices.

In addition, the external metal heat sink is conductive. If there is a leakage defect in the circuit structure of the LED candle lamp, there may be leakage current on the heat sink, which will cause unsafe hazards for users to get an electric shock.

However, if the metal radiator is canceled, there will be a problem that the LED candle lamp cannot dissipate heat efficiently
