Definitions
- Figure 1 shows an embodiment of the invention. It includes a light source, which is one or more LEDs, mounted on a heats ink.
- the output of the light source is coupled to the input end of a tapered light pipe (TLP) having an output with larger area.
- TLP tapered light pipe
- the cross- section of the TLP can be square, rectangular, circular, or other shapes.
- the TLP transforms the light from small area, large angle at the input to large area, small angle at the output.
- the output face of the TLP can be flat, but for more effective transformation, the output surface of the TLP is made convex.
- the output of the TLP is then coupled to a hollow light pipe with reflective walls inside.
- the hollow light pipe guides the light toward the output end.
- a mirror is used to reflect part of the light back to die hollow light pipe, TLP and the light source for recycling.
- the un-reflected light exits through the aperture, which is the output of the system.
- the output aperture can be square, rectangular, circular, etc. The light reflected back to the light source will be redirected towards the output together with the emitted light, increasing the brightness of the system.
- FIG 2a shows an embodiment of the invention applied to a light combining system.
- the system includes two of more of the recycling light system module (RLSM) as shown in Figure 1.
- RLSM recycling light system module
- Each RLSM consists of LEDs with color different from the others, As shown in Figure 2a, it consists of 3 RLSMs, one is RED, one is GREEN, and one is BLUE. These are the 3 primary color, when combined, produces color displays.
- a 4- color system can also be made using 4 RLSMs. for example, with RED, GREEN, BLUE, and YELLOW.
- FIG. 2a shows the outputs of the 3 RLSMs as shown in Figure 2a.
- Figure 2b shows the X-Cube indicating the reflective surface and apertures used.
- the reflective surface and aperture can be made as part of the X- Cube, or can be part of the hollow light pipe with the RLSM.
- Figure 3a shows an embodiment with two or more RLSMs assembled together producing combined output with recycling. As shown in Figure 3a, it is a 2 x 2 system consisting of 4- RLSMs with rectangular TLPs, and with, end view as shown in Figure 3b.
- Four independent hollow light pipes can be used.
- a single hollow light pipe is used with a single aperture for the output. A smal l portion of light from one light pipe can be reflected to the neighboring light pipe in the recycling process, which is fine as the light will be recycled by the neighboring LED,
- the TLP can be made with, glass or plastic. They can be polished or molded, A.R coatings can be added to the end surfaces.
- the hollow light pipes can be made with glass, plastic, or metal with reflective coating in the inside.
- the output mirror with aperture can be made with glass, plastic, or metal.
- the tapered light pipe transforms light from large angle to small angle desi gned to match the requirement of the application.
- It can be used for flashlight, search light, or spot light applications where the output from the RLSM can be collimated or have divergence changed with lenses.
- the combined output from the X-Cube can be used for projectors, entertainment lighting systems, and spot lights.
