Problems solved by technology

At present, in the existing LED bulb lamp, the LED chip is welded on the PCB circuit board, and the lower part of the circuit board is connected to the radiator. The radiator adopts a tubular structure, and the bottom of the radiator is directly connected to the lamp holder. Form a closed space, mainly relying on the closed space for heat dissipation; this heat dissipation mode cannot achieve convective heat dissipation, and the heat can only flow inside the closed space and cannot be taken out of the LED bulb quickly, making the LED bulb The lamp maintains a high temperature for a long time, resulting in low heat dissipation efficiency, which cannot fundamentally solve the heat dissipation problem of LED bulb lamps

Abstract

The invention relates to a light emitting diode (LED) lamp fittings, in particular to an inner shaft radiation type LED bulb. The inner shaft radiation type LED bulb, from the bottom to the top, comprises an LED bulb holder, an LED power supply, a radiator, a printed circuit board (PCB), an LED chip and an LED lens. The LED bulb is characterized by also comprising a radiation cover, wherein the lower end of the radiation cover is connected with the LED bulb holder, and the upper end of the radiation cover is connected with the LED lens; and the radiator is positioned in the radiation cover. In the LED bulb, the radiator is arranged, a radiation space is formed between the radiation cover and the radiator, and the axial aluminum radiator is arranged under the PCB printed circuit board, so that heat can be quickly transferred from the LED bottom; and the radiation cover provides an opening convection environment for LED radiation, and the emitted heat can exchange heat with air outside the LED bulb, so that quick radiation is realized.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an inner shaft heat dissipation LED bulb lamp. Background technique [0002] As a new type of energy-saving lighting source in the 21st century, LED lights have the characteristics of high luminous efficiency, long life, low radiation, low voltage, small size, fast start-up speed, safety, environmental protection, shock resistance and pressure resistance, and easy control. commonly used by people. There are many types of LED lamps, including LED bulb lamps, LED tube lamps, LED solar lamps and so on. The core light-emitting part of the LED lamp is the LED tube core. The LED tube core will generate a lot of heat during work. If the heat is not discharged in time, it will affect the service life of the LED tube core. This is also the main factor affecting the service life of the LED lamp. . [0003] In order to solve this problem, most LED lamps are equipped with radiators, which solves the proble...
