[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of the detachable anti-cross-light light guide lens provided by the utility model. The detachable anti-cross-light light guide lens includes a PCB board 10, at least two lamp body components 20 arranged on one side of the PCB board 10, and a shell 30 covering the outside of the PCB board 10. The detachable anti-cross-light light guide lens also includes some other functional modules, such as a connection structure arranged between the PCB board 10 and the shell 30, and a power supply component connected to the PCB board 10 and the lamp body component 20, etc., which should be technologies well known to those skilled in the art and will not be described in detail one by one here.

[0016] The PCB board 10 includes a main body 11 and at least one chip 12 disposed on the main body 11. The main body 11 is a bottom plate for carrying the above-mentioned functional modules, and is provided with a circuit structure connecting the chip and the lamp body assembly 20. The chip 12 is used to control the light emission of the lamp body assembly 20, and includes components such as a control chip and a resistor, which is a prior art and should be well known to those skilled in the art, so only a brief description is given here.

[0017] The number of the lamp body components 20 is at least two. In this embodiment, the number of the lamp body components 20 is five, and the lamp body components 20 are arranged at equal distances. All the lamp body components 20 are arranged to form a straight line.

[0018] Each of the lamp body components 20 includes an LED lamp 21 disposed on the PCB board 11, a lens 22 inserted into the housing 30 and corresponding to the position of the LED lamp 21, and a sleeve 23 sleeved outside the lens 22. At least one connecting rod 24 is respectively disposed between adjacent lenses 22 to connect all the lenses 22 to form a whole, which is convenient for installation and removal.

[0019] The lens 22 is cylindrical. The lens 22 includes a base 221 inserted into the sleeve 23, and a light-emitting portion 222 arranged at one end of the base 221 away from the LED lamp 21. The base 221 and the LED lamp 21 are arranged at intervals. The base 221 is located in the shell 30, and the light-emitting portion 222 passes through the shell 30 and exposes the end. The cross-sectional radius of the base 221 is larger than the cross-sectional radius of the light-emitting portion 222, so that an annular step is formed at the connection between the base 221 and the light-emitting portion 222, and the plane of the annular step is bonded to the shell 30 by an adhesive such as glue.

[0020] The end of the base 221 close to the LED lamp 21 and the end of the light emitting portion 222 are respectively convex along the axis direction of the lens 22. The light emitted by the LED lamp 21 is refracted through the two ends of the lens 22 to form convergent light, thereby ensuring the brightness of the light and facilitating accurate observation by the user.

[0021] The sleeve 23 is made of opaque material, such as opaque rubber or opaque plastic or aluminum alloy shell, etc. One end of the sleeve 23 is abutted and fixed to the PCB board, and the other end is flush with the end surface of the base 221. Glue is applied between the end of the sleeve 23 that is flush with the end surface of the base 221 and the shell 30 to adhere to the shell 30. Adjacent sleeves 23 are fixedly connected to form a whole. When a sleeve 23 is loosened from the shell 30, the remaining sleeves 23 can assist the sleeve 23 in positioning to ensure the light-shielding effect.

[0022] The housing 30 is made of opaque material, such as opaque rubber or opaque plastic or aluminum alloy. A mounting hole 31 is provided on the housing 30 at a position corresponding to the lens 22 , so that the light emitting portion 222 of the lens 22 can pass through the housing 30 .

[0023] Compared with the prior art, the detachable anti-cross-lighting light guide provided by the utility model is provided with a lens 22 on one side of the LED lamp 21, and a sleeve 23 is mounted on the outside of the lens 22, and the two ends of the sleeve 23 are respectively against the PCB board 10 and the inner wall of the shell 30 and are covered on the outside of each LED lamp 21, thereby isolating the light of the adjacent LED lamps 21 to avoid cross-lighting. The two ends of the lens 22 are convex surfaces, so that the light emitted from the LED lamp 21 can be converged to improve the brightness of the light and facilitate observation by users.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
