2. The lens 100 is detachably connected with the housing 210, so that an operator can quickly disassemble and assemble the damaged housing 210 or lens 100, thereby improving the maintenance speed. In addition, since the incident portion 122 is formed with at least two inclined incident surfaces, the incident area of light can be further increased, so that the incident intensity of light is enhanced, the utilization rate of light is further increased, the light intensity of the light-emitting surface 111 is further enhanced, and the light of the light-emitting surface 111 can provide sufficient light and a visual field for the dartboard.
The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
