System for collimating and concentrating direct and diffused radiation
| Details |
Inventors: Vandenberg, Leonard B.;
Assignee: Vandenberg; Leonard (Scotia, NY)
Primary Examiner: Yeung; James C.

Attorney, Agent or Firm: Klarquist Sparkman, LLP
A method is disclosed for collimating light energy falling randomly from myriad directions on a fixed-positioned thin flat surface. The collimated rays are then concentrated by an assembly of prismatic slabs and optical or fiber optic means to achieve light concentrations of 700 or more times than that of normal sunlight. Applications are given for new products such as collimated beam non-blinding motor vehicle headlights; fixed-positioned solar collectors that collect and concentrate more than 80% of the direct and diffused radiation falling on their surfaces; generation of high pressure steam by means of solar energy; and efficient and economical photovoltaic and thermoelectric generators and fiber optic acceptors for concentrating and transmitting significant quantities of light energy. |

DETAILED DESCRIPTION I claim: 1.
Apparatus for collimating direct and diffused radiation, comprising: (a) a first collimator for receiving incident radiation, (b) a first lens operatively connected to the collimator, for concentrating radiation transmitted through the collimator, (c) a light funnel for further concentrating radiation that has been concentrated at least in part by the first lens, wherein the light funnel comprises an elongated v-shaped trough member, with two tapered side walls, each side wall having an upper edge and a bottom portion, the bottom portions adjoining each other while the upper edges being widely spaced apart, (d) a receiver positioned to receive radiation that has been focused at least in part by the first lens, and (e) a heat transfer system operatively connected to the receiver, for removing heat or energy from the receiver.
2.
The apparatus of claim 1, wherein each tapered side wall widens in thickness from top to bottom.
3.
Apparatus for receiving, collimating, concentrating, and absorbing diffused solar radiation, comprising: (a) a substantially flat and stationary collimator optically positioned to receive, collimate, and transmit diffused solar radiation; (b) a substantially stationary lens optically positioned to receive, concentrate, and transmit radiation transmitted by the collimator; (c) a light funnel optically positioned to receive, further concentrate, and transmit radiation that has been concentrated by the lens, the light funnel being wider at its end receiving said radiation than at its end transmitting said further concentrated radiation, wherein the light funnel comprises an elongated v-shaped trough member, with two tapered side walls, each side wall having an upper edge and a bottom portion, the bottom portions adjoining each other while the upper edges being widely spaced apart, and (d) a substantially stationary radiation-absorbing receiver optically positioned to receive and absorb radiation concentrated by the lens.
