Abstract: In a LED warning light, straight light units are fixed to straight peripheries of a warning light body, and curved light units are fixed to joints adjacent to two respective straight peripheries. Each straight light unit includes a light base, a reflective plate, a heat dispersion cover and a front cover. LED lights are arranged on the light base. The front cover is perpendicular to the light base opposite to the reflective plate. The reflective plate has light reflective elements connected to each other in a straight line. Light rays emitted from the LEDs are reflected by the reflective plate and then given off perpendicularly to the front cover. The vertical distance from an upper periphery of the arc top of the light reflective element to the corresponding inner surface of the heat dispersion cover is more than or equal to zero.

Abstract: The present patent application provides a slim light bar. The light bar includes a base (1), two upper side covers (2), a top cover (3), a straight light unit (4), a curved light unit (5) and a plurality of supporting legs (6). The top cover (3) is disposed in the middle of the top of the base (1). The upper side covers (2) are disposed at the two ends of the top of the base (1). The straight light unit (4) is connected to the straight sides of the base (1). The curved light unit (5) is connected to the curved sides of the two ends of the base (1). The supporting legs (6) are connected to the bottom of the base (1). The height of the base (1) is 26 mm to 29 mm. The present patent application uses LEDs with a diameter of 4.5 mm and the corresponding lenses have a maximum diameter of 14 mm so that the height of the base (1) is only 26 mm to 29 mm and the materials used for making the light bar are saved.
