FLUORESCENCE-LIKE LED ILLUMINATION UNIT AND APPLICATIONS THEREOF

摘要

A fluorescence-like LED illumination unit and various applications thereof are disclosed, wherein the fluorescence-like LED illumination unit comprises a radiator (100), an LED substrate (400) fixed on the radiator (100), and multiple LED illuminants (410) encapsulated on the LED substrate (400). The first face (110) of the radiator (100) is in the shape of paraboloid (161) with reflective effect; a bar-shaped convex lens (500) with radially converging effect is provided in the space surrounded by the paraboloid (161); the bar-shaped convex lens (500) located in front of the multiple LED illuminants (410) radially converges part of the light rays emitted by the multiple LED illuminants (410) but axially diffuses it. The illumination unit emits uniform and soft light rays, with a high brightness in the irradiated region and a light emitting mode which is basically not different from that of a conventional daylight lamp, and meets the long-term using habit and approval of people.
