摘要： An LED light, such as used as a vehicle backup light, includes an LED board having first and second sides. At least one LED is mounted on the first side. A lens is positioned at a distance from the LED board to face the first side of the LED board. A potting compound is provided on the second side of the LED board. The potting compound can completely fill the second side of the LED board. The lens can include a first surface facing an external side of the LED light that is substantially smooth, to prevent collecting dust therein, and a second surface facing the LED board. That second surface can be contoured to include an upper region to refract light in a first direction, a lower region to reflect light in a second direction opposite to the first direction, and a middle region including horizontal grooves. That middle region may diverge light in a horizontal direction and converge light in a vertical direction.
