Definitions
- Figure 1C is a perspective illustration showing in further detail an array of LED collimation optics modules of figures IA and IB;
- an LED chip package 30 provides light to an optical conductor 32 that mixes the light.
- a CPC 34 is coupled to the optical conductor 32 to collimate the light received from the optical conductor 32. Following collimation, light exits the luminaire 10 as a substantially homogenous pupil. Components of or the entirety of the luminaire 10 may be considered an optics module for stage lighting and related applications.
- FIGs 2 and 3 depict other embodiments of the LED collimation optics modules 16.
- the LED collimation optics modules 16 are positioned in a single layer circular spaced-packing arrangement 36.
- the LED collimation optics modules 16-1 through 16-6 are respectively centered at peripheral points about a centrally positioned module, the LED collimation optics module 16-7.
- the spacing between the LED collimation optics modules 16 is approximately 0.19 inches (3 mm).
- the elongated base member 44 may comprise an electrically insulative housing 46, made for example, of plastic or ceramic that encases a metal heat sink with a silicon submount disposed thereon.
- the metal heat sink provides heat sinking to the LED chip package 30 disposed thereon. Further heat dissipation is provided by the heatsink subassembly 18 which, as alluded, includes a virtually silent fan that furnishes forced-air cooling proximate to the metal heat sink.
- the elongated base member 44 may further include lead wires, which are electrically isolated from the metal heat sink and the LED chips G, R, B, W by the housing. Bond wires electrically connect the LED chips G, R, B, W to the lead wires.
- the optical conductor 32 has at a first end an input aperture 48 of a cross-sectional area ⁇ r ⁇ , wherein the radius is r h and at a second end an output aperture 50 of a second cross- sectional area ⁇ r-i , wherein the radius is r 2 .
- the optical conductor 32 is superposed on the LED chip package 30 and the LED chips G, R, B, W to receive the light from the sources at the input aperture 48 and deliver the light to the output aperture 50.
- the first cross-sectional area ⁇ r ⁇ may be substantially equal to the second cross-sectional area ⁇ r ⁇ so that the input aperture 48 and output aperture 50 have substantially equal diameters and r ⁇ may equal r 2 .
- Figure 5A depicts a single light beam traversing the LED collimation optics module 16- 4.
- the optical conductor 32 which may be a light-mixing rod or lightpipe, homogenizes the light bundle transmitted therein by the light sources.
- the intensity centroid of the light bundle moves in a longitudinal fashion from the input aperture 48 to the output aperture 50.
- the reflecting surfaces of the reflecting material 54 disposed along the light-mixing rod include surface normals that are perpendicular or inclined relative to the longitudinal or axial direction of the movement of the light therethrough.
- the reflective material furnishing pathways, such as pathways 80, 82, for light beams to travel and thereby mix with each other.
- the LED chips (G, R, B, W) have at least a partial direction of orientation toward the interior space 56 of the optical conductor 32.
- Such a CPC construction is characterized by the all rays of light entering at the input aperture at angles smaller than +/- B 1 with respect to the axis z will exit the CPC after no more than a single reflection within the angle of +/- ⁇ 0 with respect to the axis z.
- a line 150 of peak luminous flux expresses the luminous flux in lumen (Im) as a function of current density (A/mm ).
