Referring to fig. 1 to fig. 6, in an embodiment of the present invention, the warning light 30 includes a circuit board 31, an optical lens 33 and a light-transmitting housing 35, wherein a light source 311 is mounted on a surface of the circuit board 31; the optical lens 33 is disposed on the circuit board 31 and is provided with an accommodating groove 331, the optical lens 33 covers the light source 311 through the accommodating groove 331, the optical lens 33 can diffuse light emitted by the light source 311, the optical lens 33 is further provided with a plurality of convex strips 332 on a wall surface deviating from the accommodating groove 331, and the convex strips 332 are sequentially distributed in a direction facing opposite sides of the optical lens 33; the light-transmitting housing 35 is connected to the circuit board 31 and covers the lens.

In one embodiment of the present invention, the circuit board 31 may be used to mount the light source and control the light source to perform corresponding operations (e.g., start, blink or shut down). The circuit board 31 may be a substantially rectangular parallelepiped structure, so that the shape thereof is regular and the processing and molding are convenient, and the circuit board may have a certain volume and size so that a certain amount of the light source 311 can be mounted. Of course, the present invention is not limited thereto, and in other embodiments, the circuit board 31 may have a substantially square structure or a cylindrical structure. The optical lens 33 may be used to cover the light source 311 to increase the efficiency of light utilization. And simultaneously, the light rays can primarily enlarge the illumination visual angle after being refracted by the optical lens 33. Then, under the action of the convex strips 332, the light can be refracted and diffused after passing through the convex strips 332, so that the light can be diffused again in the distribution direction parallel to the convex strips 332, and the irradiation viewing angle is further increased. So when this warning light 30 is applied to the warning light device, the definition warning light device has the left right direction that parallels with the distribution direction in proper order of a plurality of sand grips 332, and each sand grip 332 all extends the setting along upper and lower direction, and warning light 30 can have great illumination visual angle about the direction this moment to improve this warning light device at the ascending warning effect of left right direction. The light-transmitting housing 35 may be used to cover the optical lens 33, so that the light source 311 and the optical lens 33 are both located in the space enclosed by the circuit board 31 and the light-transmitting housing 35, and thus the light-transmitting housing 35 provides isolation protection for the light source.

At this time, the angle of view of the light irradiation can be increased by the refraction of the light by the tapered portion 334, thereby achieving a preliminary increase in the angle of view of the light irradiation. Of course, when the light emitted from the light source 311 partially irradiates the wall of the tapered portion 334 adjacent to the notch of the receiving slot 331, some of the light may be directly refracted to the outer surface of the flat plate portion 333. At this time, the flat plate portion 333 is configured such that the light refracted to the outer surface of the flat plate portion 333 from the outer circumferential surface of the tapered portion 334 or the light refracted to the outer surface of the flat plate portion 333 directly from the groove wall of the notch of the tapered portion 334 adjacent to the containing groove 331 refracts on a plurality of protrusions, so as to further increase the irradiation angle of the light in the left-right direction (as shown in fig. 5, the dotted line with an arrow in fig. 5 represents the light path).
