Embodiment 1

[0025] like figure 1 As shown, a light concentrating and combining system for multiple LED light sources includes an LED light source 1, a light combiner 2 and a condenser lens group 3 in sequence according to the direction of the light path.

[0026] like figure 1 As shown, the LED light source 1 includes an LED substrate and more than three groups of LED lamp bead units 11 arranged on the same plane and evenly distributed on the LED substrate. Since the LED light source 1 has a powerful light-gathering accessory, the LED lamp bead The spacing between the units 11 can be relatively large, and the heat treatment is simpler. Each LED lamp bead unit 11 of the LED light source 1 is the same, and the LED lamp bead unit 11 is a single-color lamp bead, an all-in-one color lamp bead or a combination of multiple small lamp beads, wherein the small lamp bead can be a single color or color.

Embodiment 2

[0031] like figure 2 As shown, a light concentrating and combining system for multiple LED light sources includes an LED light source 1, a light combiner 2, a condenser mirror 4, and a light output mirror 5 in sequence according to the direction of the light path.

[0032] like figure 2 As shown, the LED light source 1 includes an LED substrate and more than three groups of LED lamp bead units 11 arranged on the same plane and evenly distributed on the LED substrate. Since the LED light source 1 has a powerful light-gathering accessory, the LED lamp bead The spacing between the units 11 can be relatively large, and the heat treatment is simpler. Each LED lamp bead unit 11 of the LED light source 1 is the same, and the LED lamp bead unit 11 is a single-color lamp bead, an all-in-one color lamp bead or a combination of multiple small lamp beads, wherein the small lamp bead can be a single color or color.

Abstract

The invention provides a light condensation and composition method for multiple LED light sources. An optical system based on the method sequentially comprises the LED light sources, a light composition device and a condensing lens according to the direction of an optical path. Each LED light source comprises three or more LED bead units located on the same plane, and the distances between every two adjacent LED bead units are identical. The light composition device comprises three or more light guide columns which are in one-to-one correspondence with the LED bead units. A light inlet of each light guide column is opposite to the corresponding LED bead unit, and the diameter of the light inlet is larger than that of the light emitting face of the corresponding LED bead unit. The condensing lens is close to the light outlet surface of the light composition device. Light rays emitted by the LED bead units are mixed uniformly through total reflection in the light guide columns, the light outlets of all the light guide columns form the light outlet surface of the light composition device, and even light spots are formed on the light outlet surface of the light composition device; and even light spots with smaller angles are formed through further focusing of the condensing lens.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a system and method for concentrating and combining light of multiple LED light sources. Background technique [0002] At present, the combined light and concentrated light method of multiple LEDs is generally achieved by changing the luminous angle of each LED light bead of the LED light source, such as a multiple LED light bead combined light imaging system with Chinese patent publication number 202432431 Including the light-combining part and the imaging part, the light-combining part includes more than two LED lamp beads, and each LED lamp bead is equipped with a concentrating device that gathers the flux of the LED lamp bead within 5~15 degrees. The devices form a light concentrating device group, and a light combining lens is arranged in front of the light concentrating device group. The optical system has high requirements on the light-gathering device, the light is first conc...
