Embodiment Construction

[0017] according to figure 1 , the LED general-bubble bulb is mainly divided into two parts: a glass bulb 12 and a lamp cap 6. A plurality of LED lamp beads 2 in the glass bulb 12 are aggregated on the illuminant bracket 1 connected with the metal base 14 to form an LED illuminant, and the LED illuminant It is screwed on one end of the metal heat conducting element 3 with heat dissipation fins. The stem 8 with the metal wire 13 is connected to the other end of the metal heat conduction element 3 through the elastic sleeve 11, and the heat conduction glue 10 is filled therebetween to ensure its good heat conduction performance. The glass bulb 12 is fused together with the stem 8 . The air in the glass bulb is evacuated through the sealing exhaust pipe 7 and then filled with heat-conducting gas helium, and the whole glass bulb 12 is a closed body. The metal heat sink 4 is fixed on the tail of the glass bulb, and a thermal conductive glue 9 is filled between the metal heat sink...

Abstract

The invention provides a common LED lamp bulb, which comprises a core column and a lamp holder which are in sealing connection with a glass envelope, wherein the bottom part of a hollow metal heat-conducting lamp column is connected with the core column through a heat-conducting adhesive; the side wall of the top part of the hollow metal heat-conducting lamp column is embedded with LED lamp beads; the tail part of the glass envelope is connected with the lamp holder through an external metal radiation piece and a plastic transitional piece; the heat-conducting adhesive is arranged between the tail part of the glass envelope and the metal radiation piece; a heat-conducting gas is charged in the glass envelope. The common LED lamp bulb solves a radiation problem that a component formed by assembling a plurality of groups of LED lamp beads influences the service life of the LEDs in use when a common lamp envelope is adopted.

Description

technical field [0001] The invention relates to an LED common bubble type light bulb. Background technique [0002] For a long time people have been accustomed to using ordinary incandescent bulbs as the lighting source for daily life. Due to the low luminous efficiency and high energy consumption of incandescent bulbs, they have been gradually banned by many countries in recent years. How to combine the shape of incandescent bulbs with the characteristics of low power, low energy consumption, high luminous efficiency, and long life of LEDs? The key problem to be solved is that the components composed of multiple sets of LED lamp beads will affect the long life of LEDs during use. cooling problem. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the above problems, to provide an LED ordinary bulb with low energy consumption, fast heat dissipation and long service life. [0004] The present invention is achieved...
