Description

Technical Field

[0001] The utility model relates to the technical field of LED bulbs, in particular to a high-efficiency heat dissipation type LED bulb. Background Art

[0002] The bulb is a new energy-saving lamp that replaces the traditional incandescent bulb. The traditional incandescent lamp has high energy consumption and short lifespan. In the context of global resource shortage, it has gradually been banned by governments around the world. The subsequent replacement product is the electronic energy-saving lamp. Although the electronic energy-saving lamp improves the energy-saving effect, it uses many heavy metal elements that pollute the environment, which goes against the general trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the only choice for new green lighting. LED is far superior to traditional lighting products in terms of light-emitting principle, energy saving and environmental protection. LED is a commonly used light-emitting device that releases energy through the recombination of electrons and holes. It is widely used in the lighting field. Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society.

[0003] Chinese patent CN216383662U discloses a new type of LED bulb lamp with high efficiency and heat dissipation, comprising a base for installation and fixation, a heat dissipation tube connected and installed below the base, and a light-transmitting cover connected and installed below the heat dissipation tube. The base comprises an electrode contact connected and installed at the top, a connecting thread provided on the side wall of the base, a connecting pipe connected and installed at the bottom of the base, a connecting cable provided inside the connecting pipe, and a ventilation hole provided on the side wall of the connecting pipe. A connecting pipe is provided below the base, and the connecting cable is placed inside the connecting pipe and connected to the circuit board, so that the heat dissipation tube is separated from the light-transmitting cover to prevent dust from entering the light-transmitting cover and affecting the light. A thermal conductive pad is provided at the bottom of the light-transmitting cover to accelerate heat conduction and ensure uniform temperature throughout the light-transmitting cover to prevent cracking. A heat dissipation tube is provided. When the bulb lamp is in operation for a long time, a heat dissipation fan is started to dissipate the high temperature generated inside through the thermal conductive pad and the heat dissipation hole to ensure the normal operation of the LED bulb lamp. However, this structure has certain defects, such as poor thermal conductivity, difficulty in dissipating heat, and easy to cause short circuit, which is difficult to meet the user's usage requirements.

[0004] Therefore, in order to solve such problems, we propose an efficient heat dissipation type LED bulb. Utility Model Content
