[0035] As Figure 1 and Figure 2As shown, the lamp barrel 100 is a hollow cylindrical structure with openings at both ends. The lamp barrel 100 can be a cylindrical barrel, a square barrel or other cylindrical shapes. The interior of the lamp barrel 100 is hollow to form an inner cavity 110. The first lamp group 200 is installed on the outer wall of the lamp barrel 100 and is installed along the circumferential direction of the lamp barrel 100. The driving board 300 and the second lamp group 400 are both installed in the inner cavity 110. The driving board 300 is a circuit board integrated with electrical components and circuits such as capacitors, resistors, multi-stage tubes, and controllers. The first lamp group 200 can be electrically connected to the driving board 300 through a conductive structure such as a wire or a conductive sheet. The second lamp group 400 can be electrically connected to the driving board 300 through a conductive structure such as a wire or a conductive sheet. As Figure 7 and Figure 8 , the first lamp group 200 and the second lamp group 400 can be monochromatic lights or color-changing lights. The driving board 300 controls functions such as the on / off or color change of the first lamp group 200 and the second lamp group 400. The light-transmitting component 500 is installed at one end of the lamp barrel 100, and the light-transmitting component 500 can be used to cover one end of the lamp barrel 100. The second lamp group 400 irradiates outward through the light-transmitting component 500. The conductive base 600 is installed at the other end of the lamp barrel 100, and the conductive base 600 can be a component such as a threaded conductive head. The driving board 300 and the conductive base 600 can be electrically connected through a structure such as a wire or a conductive sheet. Specifically, the driving board 300 can be connected to the end of the conductive base 600 through a live wire and to the side wall of the conductive base 600 through a neutral wire. During use, the conductive base 600 can be connected to the mains system, and the first lamp group 200 and the second lamp group 400 are controlled to emit light through the conductive base 600 and the driving board 300. The first lamp group 200 irradiates directly in all directions around the lamp barrel 100, and the second lamp group 400 irradiates outward through the light-transmitting component 500, thereby realizing multi-directional and multi-angle lighting of the LED bulb. The first lamp group 200 and the second lamp group 400 can be set to the same or different lamp colors, brightness, etc. to achieve diversified lighting.

[0036] In some specific embodiments of the present invention, such as Figure 1 and Figure 2As shown, the first lamp group 200 includes a first flexible circuit board 210 and a plurality of first lamp beads 220 mounted on the first flexible lamp board. The first lamp beads 220 are preferably LED lamp beads. The first flexible circuit board 210 can be bent for use. The first flexible circuit board 210 and the driving board 300 can be electrically connected through wires or other conductive components. The first flexible circuit board 210 can be one or more pieces, and the first flexible circuit board 210 is mounted on the outer wall of the lamp cylinder 100. Among them, one side of the first flexible circuit board 210 is the mounting surface 211 for mounting the first lamp beads 220, and the other side is the connection surface 212. Adhesive can be provided on the connection surface 212, and the connection surface 212 is attached to the outer wall of the lamp cylinder 100 through the adhesive. In this embodiment, the first flexible circuit board 210 is set to be one piece, and the first flexible circuit board 210 is wrapped around the outer wall of the circumferential line of the lamp cylinder 100. The plurality of first lamp beads 220 are distributed on the mounting surface 211, so as to irradiate all around the lamp cylinder 100.

[0037] Further, as Figure 6 shown, a wire passing hole 120 is provided on the side wall of the lamp cylinder 100. The first flexible circuit board 210 and the driving board 300 are connected by a wire. The wire passes through the wire passing hole 120 and extends into the inner cavity 110. One end of the wire is welded to the first flexible circuit board 210, and the other end is welded to the driving board 300. If the first lamp group 200 is set to be capable of emitting variable-color light, then several wires are welded to the first flexible circuit board 210 according to actual needs and are electrically connected to the driving board 300.

[0038] In some embodiments of the present invention, the second lamp group 400 is integrally provided on the driving board 300 and is installed into the inner cavity 110 together. The substrate of the driving board 300 can be a rigid board.

[0039] In some embodiments of the present invention, as Figure 1 shown, the substrate of the driving board 300 is a second flexible circuit board 310. The second flexible circuit board 310 can be bent and deformed to a certain extent for use. The second lamp group 400 includes a third flexible circuit board 410 and second lamp beads 420 mounted on the third flexible circuit board 410. The second lamp beads 420 are preferably LED lamp beads. The third second flexible circuit board 310 can be bent and deformed to a certain extent for use. The second flexible circuit board 310 and the third flexible circuit board 410 can be electrically connected through a wire, and the second flexible circuit board 310 and the first lamp group 200 can be electrically connected through a wire. The second flexible circuit board 310 and the third flexible are placed into the inner cavity 110 and can be deformed by the extrusion of the inner cavity 110 without affecting conductivity. This can reduce the design size of the inner cavity 110.

[0040] Further, as Figure 3 and Figure 4As shown, the second flexible circuit board 310 and the third flexible circuit board 410 are integrally formed. That is, the same substrate is shared between the second flexible circuit board 310 and the third flexible circuit board 410. During use, the third flexible circuit board 410 is folded relative to the second flexible circuit board 310, and the third flexible circuit board 410 is stacked on the second flexible circuit board 310. A fixing plate 700 is provided between the third flexible circuit board 410 and the second flexible circuit board 310, and the fixing plate 700 is an insulating plate. On the one hand, the fixing plate 700 prevents the second flexible circuit board 310 and the third flexible circuit board 410 from short-circuiting when stacked, and on the other hand, the fixing plate 700 can increase the structural strength after the second flexible circuit board 310 and the third flexible circuit board 410 are stacked, and then it is fixedly installed in the inner cavity 110.

[0041] In some embodiments of the present invention, the conductive base 600 can be fixed to the lamp barrel 100 by means of bonding, snap connection or threaded connection, etc. The bonding method is through gluing, the snap connection is through a snap structure, and the threaded connection is a structure in which an external thread and an internal thread cooperate.

In some specific embodiments of the present invention, as Figure 1 and Figure 2 shown, the light-transmitting component 500 includes an inner light-transmitting cover 510 and an outer light-transmitting cover 520. The outer light-transmitting cover 520 covers the outside of the inner light-transmitting cover 510, and the inner light-transmitting cover 510 covers the second lamp group 400. The outer light-transmitting cover 520 is used to protect the inner light-transmitting cover 510. The second lamp group 400 irradiates outward through the inner light-transmitting cover 510 and the outer light-transmitting cover 520 in sequence. The inner light-transmitting cover 510 can be selected from components of different shapes, and the light of the second lamp group 400 forms a specific shape and projects outward through the inner light-transmitting cover 510.

[0043] Furthermore, as Figure 5 and Figure 6 shown, a clamping convex 130 is provided on the inner wall of the end of the lamp barrel 100. The inner light-transmitting cover 510 is provided with a clamping groove 511 along the circumference. During installation, the inner light-transmitting cover 510 is placed on the end of the lamp barrel 100, the clamping convex 130 and the clamping groove 511 are aligned, and then the inner light-transmitting cover 510 is rotated so that the clamping convex 130 slides into the clamping groove 511, thereby fixing the inner light-transmitting cover 510 on the end of the lamp barrel 100. The outer light-transmitting cover 520 can be fixed to the lamp barrel 100 by means of glue, snap connection, etc.
