Abstract

The invention discloses an LED bulb lamp. The LED bulb lamp is formed by sequential connection of a lamp holder, a lamp socket, a radiator, an LED lamp panel and a lamp shade, a circuit board is arranged inside the lamp socket, an LED lamp bead is arranged on the LED lamp panel, the LED lamp panel is fixed on the radiator through an LED lamp panel containing groove, the lamp shade is clamped on the radiator, a chimney-type cooling channel is arranged on the inner wall of the radiator, and cooling fins are arranged on the outer wall of the radiator. According to the bulb lamp, dual cooling schemes such as chimney-type cooling and fin-type cooling are provided, heat produced by the LED bulb lamp is emitted from the chimney-type cooling channel through air convection, and the heat produced by the LED bulb lamp is led into cooling fins in a heat conduction mode to be subjected to heat exchange in the air to reduce the temperature inside the bulb lamp, so that the cooling effect of the LED bulb lamp is improved, and the service life of the LED bulb lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED bulb lamp. Background technique [0002] Due to the long service life of LED lamps, low energy consumption, and significant energy saving, LED lamps have been widely used in daily life as light sources, such as LED bulb lamps. However, with the increase in the number of LEDs in the LED bulb lamp, as well as the increase in power and brightness, the heat generated by the LED lamp during operation has risen sharply. Therefore, how to improve the heat dissipation effect of the LED bulb lamp has become a major problem in the technology of the LED bulb lamp. [0003] In the prior art, an LED bulb lamp includes: a substrate, an LED lamp and a power module arranged on the substrate, and a heat dissipation device. When the LED bulb lamp is working for lighting, the heat generated by the LED lamp is transmitted to the heat sink through the substrate, and then radiated out by the...
