Referring to fig. 1A to fig. 1G, the warning light 10 of the present embodiment includes a base 100 and two light source assemblies 600. The base 100 extends along the extending direction f1 and has an elongated shape, and the two light source assemblies 600 are respectively coupled to two sides of the base 100 in the extending direction f1 (the X-axis direction in fig. 1A). Specifically, the base 100 has two opposite openings 150 in the extending direction f1, and the two second light source assemblies 600 are respectively assembled in the two openings 150. The second light source assembly 600 may be coupled to the opening 150 by, for example, engaging or clamping.

In the present embodiment, each light source assembly 600 includes a light emitting module 610 and a lamp housing 620. The light emitting module 610 includes a substrate 611 and a plurality of light emitting elements 612. The substrate 611 has a mounting surface 613, and the light emitting element 612 is disposed on the mounting surface 613. The light emitting elements 612 are aligned in a row along the arrangement direction f2 (the Z-axis direction in fig. 1A). The lamp housing 620 includes a lamp housing body 621 having an accommodating space S for accommodating the light emitting module 610, and the lamp housing body 621 includes a light emitting surface 622 disposed opposite to the light emitting element 612. Along the arrangement direction f2, the light emitting surface 622 has a first light emitting area 623 parallel to the arrangement direction f2 and two second light emitting areas 624 located at two sides of the first light emitting area 623 and inclined to the setting surface 613. The second light-exiting region 624 inclined to the mounting surface 613 deflects a portion of the light emitted from the light-emitting element 612 in the Z-axis direction.

In the present embodiment, each light emitting device 612 is a light emitting diode or a solid state light emitting device different from a conventional light source.

As shown in fig. 1B, in the present embodiment, the first light emitting areas 623 are flat surfaces, and each of the second light emitting areas 624 is a curved surface having a dioptric effect of a convex lens. The light L1 emitted from the light emitting element 612 opposite to the first light emitting region 623 can be directly emitted from the first light emitting region 623. Since the second light exiting region 624 has a curved surface, the light L2 emitted from the light emitting element 612 can be effectively dispersed.

As shown in fig. 1A and 1B, in the present embodiment, each light source assembly 600 further includes two side-emitting modules 630, and in the arrangement direction f2, the two side-emitting modules 630 are disposed on the substrate 611 and located at two sides of the light-emitting element 612. Each side light emitting module 630 is used for emitting light towards each second light emitting area 624. Specifically, each side light module 630 is configured to emit light toward a portion of each second light exiting region 624 farthest from the first light exiting region 623, so as to avoid a dark region in a local area of the warning light 10. Each side light emitting module 630 includes a carrier 631 vertically connected to the mounting surface 613 of the substrate 611 and at least one side light emitting element 632 disposed on the carrier 631.

As shown in fig. 1C, in the present embodiment, in a cross-sectional view in a direction (i.e., the extending direction f1) parallel to the disposing surface 613 and perpendicular to the arranging direction f2, the light emitting surface 622 is a curved surface having the refractive effect of the convex lens. Therefore, the light exiting surface 622 can also effectively disperse the light emitted from the light emitting element 612 in the Y-axis direction.

In this embodiment, the lamp housing body 621 further includes a top surface 625 and a bottom surface 626 opposite to the top surface 625. The light emitting surface 622 is connected between the top surface 625 and the bottom surface 626, and the light transmittance of the light emitting surface 622 can be higher than that of the top surface 625 and the bottom surface 626. The lamp housing body 621 may have an atomizing structure (not shown) on the housing corresponding to the top surface 625 and the bottom surface 626 to reduce the transmittance, so that the light emitted from the light emitting element 612 can be emitted from the light emitting surface 622 as much as possible.
