Description

LED bulb easy to assemble and disassemble
Technical Field
The invention relates to a bulb, in particular to an LED bulb easy to assemble and disassemble.
Background
At present, an LED lamp is used as a household lighting lamp for replacing a tungsten lamp and a fluorescent lamp, and due to the advantages of low energy consumption, high lighting effect, no mercury, no radiation pollution, renewable materials and the like, the LED lamp is increasingly popular with consumers today with increasingly tense energy sources. In every day, the existing LED bulb is troublesome to disassemble and assemble, and a specific PCB (printed circuit board) needs to be fixed on a radiator by adopting screws.
Disclosure of Invention
The invention aims to solve the technical problem of providing an LED bulb easy to assemble and disassemble.
In order to solve the technical problems, the invention provides an easily-detachable LED bulb, which comprises a lamp cap, a radiator and a lampshade, wherein the lamp cap is connected with the top of the radiator, the lampshade is connected with the bottom of the radiator, a PCB is arranged below the radiator, a plurality of LED wafers for emitting light are uniformly arranged on the PCB at intervals,
the lamp shade has a drum section, the PCB board is arranged in the drum section, the top of the PCB board is connected with the cylinder, a plurality of jacks are arranged on the drum section along the circumferential direction at uniform intervals, each jack is provided with a cutting, and the cutting can be pushed to the surface of the PCB board and press the PCB board on the cylinder.
The back of the PCB is connected with the bottom wall of the radiator through a heat conducting adhesive layer.
A plurality of radiating fins are formed on the surface of the radiator at uniform intervals.
The lamp cap is detachably connected with the radiator.
The lamp cap is connected with the radiator in a threaded fit mode.
And a fluorescent layer is arranged on the outer surface of the lampshade.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, the cylindrical section is provided with a plurality of jacks at uniform intervals along the circumferential direction, each jack is provided with the cutting, and the cutting can be pushed onto the surface of the PCB and can press the PCB against the cylinder. Thus, the PCB 8 can be prevented from being fixed by screws, and the assembly and disassembly are convenient.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but the present invention is not limited thereto.
Referring to fig. 1, the LED bulb easy to assemble and disassemble of the present invention includes a lamp cap 2, a heat sink 4 and a lamp shade 6, the lamp cap 2 is connected to the top of the heat sink 4, the lamp shade 6 is connected to the bottom of the heat sink 4, a PCB 8 is disposed below the heat sink 4, a plurality of LED chips 9 for emitting light are disposed on the PCB 8 at uniform intervals, the lamp shade 6 has a cylindrical section 60, the PCB 8 is disposed in the cylindrical section 60, the top end of the PCB 8 is connected to a cylinder 62, a plurality of insertion holes 64 are disposed on the cylindrical section 60 at uniform intervals in the circumferential direction, each insertion hole 64 has an insertion strip 66 therein, and the insertion strip 66 can be pushed onto the surface of the PCB 8 and press the PCB 8 against the cylinder 62. Thus, the PCB 8 can be prevented from being fixed by screws, and the assembly and disassembly are convenient.
In addition, as shown in fig. 1, in the present invention, the back surface of the PCB 8 is connected to the bottom wall of the heat sink 4 through the thermal conductive adhesive layer, so that a large heat exchange area between the PCB 8 and the heat sink 4 can be ensured, thereby ensuring a good heat dissipation effect of the present invention. Meanwhile, a plurality of radiating fins are formed on the surface of the radiator 4 at uniform intervals, and due to the existence of the plurality of radiating fins, the radiator has a larger radiating area, and the radiating effect of the radiator can be improved, so that the radiator has a longer service life. In addition, the lamp cap 2 is detachably connected with the heat sink 4, preferably, the lamp cap 2 is in threaded fit with the heat sink 4, so that the lamp cap 2 and the heat sink 4 can be assembled or disassembled conveniently, and a user can conveniently manufacture and maintain the LED lamp. Finally, a fluorescent layer (not shown) is arranged on the outer surface of the lampshade 6, and due to the existence of the fluorescent layer, after the lamp is extinguished, residual light still exists in the fluorescent layer, so that a user can conveniently perform next action by means of the residual light, and the purpose of facilitating the user is achieved.
