Abstract

The invention relates to the technical field of bulbs, and particularly discloses an efficient radiating type LED lamp which comprises a lamp holder, a substrate seat and a lampshade. One end of the substrate seat is connected with the lamp holder, a substrate with a circuit board is arranged at the other end of the substrate seat, a plurality of LED light emitting assemblies are arranged on the substrate, the substrate seat is in the shape of a circular truncated cone, a heat conduction plate is arranged at a large-diameter end of the substrate seat, the large-diameter end of the substrate seat axially extends to form a convex ring, the substrate is mounted in the convex ring, a small-diameter end of the substrate seat inwardly and radially extends to form a clamp ring, an isolation pipe is arranged between the clamp ring and the heat conduction plate, a closed annular radiating cavity is enclosed by the substrate seat, the isolation pipe, the clamp ring and the heat conduction plate and is filled with nitrogen or inert gas, and metal sodium is arranged inside the annular radiating cavity. The efficient radiating type LED lamp has the advantages of good radiating performance and long service life.

Description

technical field [0001] The invention relates to the technical field of bulbs, in particular to a ceramic-based LED energy-saving bulb. Background technique [0002] At present, LED light bulbs have gradually replaced commonly used incandescent lamps and fluorescent lamps. LED light bulbs have the characteristics of high luminous efficiency and low power consumption, and are deeply loved by people. Due to the low power and low brightness of a single LED, it is not suitable to be used alone. However, a practical LED lighting fixture designed by assembling multiple LEDs has broad application prospects. However, the combined use of many LED chips will generate heat. If the heat emitted by the LED chips cannot be transmitted and dissipated in time, it will cause light decay and affect the service life of the LED chips. The combination of dozens of LED chips generates a lot of heat. Therefore, it becomes a big problem in the LED field to maximize the heat dissipation of LED chips...
