Abstract

A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.
