LED (Light-Emitting Diode) stage lamp lens assembly and LED stage lamp

Abstract

The invention discloses an LED (Light-Emitting Diode) stage lamp lens group. The LED stage lamp lens group comprises a collector lens for focusing light rays emitted via an LED light source, a first fly eye lens and a second fly eye lens, wherein the collector lens is provided with at least one discontinued reflecting face and is positioned between the first fly eye lens and the LED light source; the first fly eye lens and the second fly eye lens are formed via a plurality of fly eye lens units which are tightly connected together; the optical axes of the fly eye lens units of the first and second fly eye lenses are overlapped with one another, and thus the fly eye lens units of the first and second fly eye lens are in one-to-one correspondence; and moreover, the surfaces of the corresponding fly eye lens units of the first and second fly eye lenses can be embedded with one other. According to the LED stage lamp lens group provided by the invention, the light rays emitted via the LED light source are reflected, overlapped and collected via the collector lens and then are overlapped with one another on an illumination field through the first fly eye lens and the second fly eye lens, thereby forming light spots with uniform illumination transition and consistent color difference on the illumination field.

Description

technical field [0001] The invention relates to the technical field of LED stage lights, in particular to an LED stage light lens group and an LED stage light using the lens group. Background technique [0002] The LED light source is a green, pollution-free, energy-saving light source with a long service life, so the LED light source has gradually become the first choice for development and application in the lighting field. The LED light source can emit a variety of monochromatic light, and use the principle of RGB three-color light to obtain mixed light of any color by adjusting the LED current that emits red light, green light and blue light, so the LED light source can be used as a stage light. light source application. Since the emission spectrum, brightness and temperature characteristics of each color LED chip are different, when the light emitted by each color LED chip is projected onto the stage or screen through the optical system, the color uniformity of the ill...
