Inflatable LED bulb and manufacturing method thereof

Abstract

The invention relates to an LED bulb. An inflatable LED bulb comprises a bulb housing, a core column, an LED, a lamp holder and an LED driver, wherein the bulb housing and the core column are enclosed to form a gas storage chamber, and the core column is provided with an inflation channel communicated with the gas storage chamber, a bulkhead provided with an on-position jack, a first spring driving the bulkhead to seal the inflation channel, a latch inserted in the on-position jack, a floating chamber and a floating plug which is moved based on the pressure of the gas stored in the gas storage chamber and drives the latch to be pulled out of the on-position jack. The floating plug is in sealing and sliding connection in the floating chamber, the floating plug divides the floating chamber into a sealing chamber and an opening chamber communicated with the gas storage chamber, and the opening chamber is positioned on the side of the floating plug facing the latch. The inflatable LED bulb has the advantages of less heat transmitted from an LED to the core column, uniform heat radiation, and automatic disconnection when the internal air pressure reaches a set value, and solves the problem that a conventional LED is poor in heat radiation uniformity and radiated heat influences the stability of an LED driver.

Description

technical field [0001] The invention relates to LED light bulbs, in particular to an inflatable LED light bulb and a manufacturing method thereof, belonging to the lighting field. Background technique [0002] Due to the advantages of small size, low power consumption, long service life, high brightness, environmental protection and durability, LEDs are widely used in lamps. [0003] The structural form of the LED bulb is that a heat transfer body (stem) with one end located in the bulb shell is installed on the lamp cap, and an LED is installed on the inner end of the stem. [0004] In the Chinese patent application publication number CN101893180A, a patent document titled "A LED Light Bulb" discloses an LED light bulb. The light bulb in this patent includes a lamp cap, a lamp holder, a lampshade, a radiator, and The driver is provided with an independent small light-emitting area on the bulb. The small light-emitting area is composed of an independent heat sink arranged a...

AI Technical Summary

Problems solved by technology

[0007] The first object of the present invention is to provide an inflatable LED light bulb and a manufacturing method that transmit less heat to the stem from the LED, uniform heat dissipation, and can be automatically disconnected when the internal air pressure reaches a set value, which solves the problem of existing LED bulbs. The heat dissipation uniformity of the bulb is poor, and the heat dissipated has a great influence on the stability of the LED driver

[0008] The second purpose of the invention is to further provide an inflatable LED bulb with a large lighting angle, which solves the problem of the small lighting angle of the existing LED bulbs
