[0027] The following is combined with Figure 1-2 The utility model is further described in detail, but it is not intended to limit the utility model.

[0028] The utility model provides an LED lamp 22 bead, comprising a cover body 1 and a connecting plate 2, wherein the cover body 1 comprises a main body 11, wherein the main body 11 has a cavity 14 with an opening 15 at one end, wherein the connecting plate 2 is arranged in the cavity 14, wherein an adjusting device 21 is arranged on one side of the connecting plate 2, wherein an LED lamp 22 is arranged on the other side of the connecting plate 2, and wherein the adjusting device 21 is electrically connected to the LED lamp 22. The cover body 1 in the present application covers the entire connecting plate 2 in the cavity 14, and the connecting plate 2 is protected by the cover body 1 to prevent the connecting plate 2 from being damaged due to external reasons, and further protects the LED lamp 22. When the connecting plate 2 is connected to a power source, the current entering the connecting plate 2 is adjusted by the adjusting device 21, and different currents make the illumination brightness of the LED different. Meanwhile, in the present application, the adjusting device 21 is welded on the connecting plate 2, and the connecting plate 2 and the adjusting device 21 are integrated into one body, thereby greatly reducing the occupied space and preventing the adjusting device 21 from being disconnected from the LED lamp 22.

[0029] In some embodiments, the cover body 1 further includes a light focusing portion 12 , and the light focusing portion 12 is disposed on one side of the main body 11 .

[0030] Specifically, in this embodiment, the focusing portion 12 is arranged on one side of the main body 11, so that one side of the cover body 1 is convex, and the focusing portion 12 is a solid component, and the thickness of the focusing portion 12 is greater than the wall thickness of the main body 11. The focusing portion 12 can further protect the components inside the main body 11.

[0031] In some embodiments, the side of the connecting plate 2 provided with the LED lamp 22 faces the light focusing portion 12 .

[0032] Specifically, in the present embodiment, the LED lamp 22 is arranged toward the focusing portion 12. When the LED lamp 22 is turned on, the light is irradiated to the outside through the focusing portion 12, and the focusing portion 12 can concentrate the scattered light into a fixed range. For example, in the present application, the focusing portion 12 concentrates the light scattered by the LED into a circle, so that the light is more concentrated and the lighting effect is better.

[0033] In some embodiments, the cover body 1 is made of glass.

[0034] Specifically, compared to the rubber cover 1, the cover 1 with a glass structure is used in the present embodiment. Since the glass structure has better strength, higher smoothness and better penetration effect, the cover 1 in the present application is more resistant to friction and prevents the generation of static electricity that may damage the connecting plate 2. The cover 1 in the present application has better light transmittance, so that the light source emitted by the LED is more concentrated and the lighting effect is better.

[0035] In some embodiments, the cross-section of the cavity 14 is circular or rectangular, and the cross-section shape of the connecting plate 2 corresponds to the cross-section shape of the cavity 14 .

[0036] Specifically, in the present embodiment, the cross-sectional shape of the cavity 14 is circular, and the cross-sectional shape of the connecting plate 2 is also circular. After the connecting plate 2 is placed in the cavity 14, the cross-sectional shape of the connecting plate 2 corresponds to the cross-sectional shape of the cavity 14, so that the connecting plate 2 is positioned and limited by the cavity 14 to prevent the connecting plate 2 and the LED lamp 22 from being displaced, thereby causing the light source to be unfocused.

[0037] In some embodiments, the adjustment device 21 is a chip resistor.

[0038] Specifically, after the external power supply is connected to the connecting board 2 , the chip resistor limits the current flowing through, thereby controlling the magnitude of the current flowing through and preventing the excessive current from damaging the LED lamp 22 .

[0039] At the same time, the chip resistors in this application can use chip resistors with different resistance values ​​according to actual conditions, thereby improving the scope of use of this application.

[0040] In some embodiments, a lead 23 is further provided on the connection plate 2 , and the lead 23 includes a positive electrode wire and a negative electrode wire.

[0041] Specifically, the lead wire 23 on the connecting plate 2 is used to connect to an external power source, and current flows to the LED lamp 22 through the lead wire 23 , so that the external power source supplies power to the LED lamp 22 .

[0042] In some embodiments, the positive lead is connected to the adjustment device 21 and the LED lamp 22 .

[0043] Specifically, the current flows to the regulating device 21 through the positive wire, and the regulating device 21 regulates the flow of the current. Then, the current flowing out of the regulating device 21 flows to the LED lamp 22, and the LED lamp 22 lights up.
