[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1.

The third segment 330 is located above the base 110 and spaced apart from it. The bottom of the third segment 330 abuts against the second bent segment 122. The third segment 330 is provided with a first connecting hole 331 extending vertically through it. The first connecting hole 331 is opposite to and communicates with the second connecting hole 123. The two ends of the second segment 320 are respectively connected to one end of the first segment 310 and one end of the third segment 330. One end is connected; a first connector passes through the first connecting hole 331 and the second connecting hole 123, and the first connector is detachably connected to the third segment 330 and the second bent segment 122; a light-emitting element 400 is disposed on the base 110; the light-emitting element 400 includes a circuit board 410 and lamp beads 420; the circuit board 410 has a ring structure and is arranged around a vertical axis; multiple lamp beads 420 are provided and are disposed on the side end of the circuit board 410 near the vertical axis; the upper end of the circuit board 410 abuts against the bottom of the second bent segment 122.

In this embodiment of the utility model, the light-emitting element 400 is disposed on the base 110, and the light emitted by the light-emitting element 400 can be emitted outward through the diffuser plate 300; the first bent section 121 of the bent circumference 120 abuts against the side end of the base 110 away from the vertical axis, the first section 310 of the diffuser plate 300 abuts against the side end of the base 110 near the vertical axis, and the surrounding second bent section 122 abuts against the third section 330 of the diffuser plate 300, so that the bent circumference 120 and the base can be made to... The base 110, together with the diffuser plate 300, protects the light-emitting element 400 from the influence of external substances and prevents light leakage. The light-emitting element 400 is set on the base 110, and the upper end of the circuit board 410 abuts against the bottom of the second bending section 122, so that the base 110 and the bending circumference 120 can limit the position of the circuit board 410, reduce the vibration of the light-emitting element 400 between the housing 100 and the diffuser plate 300, and improve the working stability of the light-emitting element 400.

[0030] 2. In this low-cost industrial ring light source, the outer shell 100 consists of a bent circumference 120 and a base 110. The base 110 supports the light-emitting element 400, while the diffuser plate 300 is disposed on top of the base 110. The position of the circuit board 410 of the light-emitting element 400 is defined by the base 110 and the second bent section 122 of the bent circumference 120.

The third segment 330 of the diffuser plate 300 abuts, thereby making the housing 100 compatible with the diffuser plate 300. The diffuser plate 300 and the bending ring 120 can surround the light-emitting element 400, thus protecting the light-emitting element 400. Since the bending ring 120 forms the first bending segment 121 and the second bending segment 122 through bending, the processing difficulty and processing cost are low, and the replaceability is high. When the bending ring 120 or the base 110 is damaged, the bending ring 120 and the base 110 can be replaced accordingly, and the replacement cost is also low.

[0034] Specifically, a first limiting groove 111 is provided on the top of the base, a second bending segment 122 of the bending circumference 120 is located above the first limiting groove 111, a light-emitting element 400 is located inside the first limiting groove 111, the top and bottom of the circuit board 410 of the light-emitting element 400 abut against the second bending segment 122 and the bottom wall of the limiting groove, respectively, while the side of the circuit board 410 away from the light-emitting element abuts against the side wall of the limiting groove.

[0035] Reference Figure 3 and Figure 4 In some embodiments of this utility model, the side wall of the first limiting groove 111 away from the vertical axis is an inclined surface 114. The side end of the circuit board 410 away from the light-emitting element 400 abuts against the inclined surface 114, so that the circuit board 410 is inclined in the first limiting groove 111, thereby making the lamp beads 420 on the circuit board 410 face the inclined direction, controlling the light emission direction of the light-emitting element 400. Furthermore, since the circuit board 410 is a ring structure, the light emission direction of the light-emitting element 400 is inclined towards the vertical axis, improving the light-gathering effect.

The first bent section 121 of the circumference abuts against the bottom wall and side wall of the third limiting groove 113 to prevent the first section 310 of the diffuser plate 300 from moving excessively in the direction close to the vertical axis.

[0047] Specifically, the second bent segment 122 of the bent circumference 120 abuts against the third segment 330 of the diffuser plate 300 and is connected by the first connector.
