Accordion mount for solar cells including point-of-purchase display with leds
First Claim
1. An energy converting assembly for operative association with a light source mounted in a housing, comprising:
- (a) a solar cell;
(b) mounting and spacing means for mounting said solar cell and for occupying space between a light source and a housing for the light source, and having a first portion and a second portion remote from aid first portion;
(c) means for holding said solar cell on said first portion of said mounting means;
(d) means disposed on said mounting means second portion for connecting said mounting means to the housing for the light source, so that the solar cell is positioned by the mounting means in close proximity with the light source, with the mounting and spacing means occupying space between the housing and the light source;
(e) a display electrically connected to said solar cell, and powered thereby when the solar cell receives light rom the light source; and
wherein said mounting and spacing means comprises sheet material having first and second faces, and an undulating configuration between first and second opposite side edges thereof, said first portion comprising part of said first face at an undulation substantially centrally between said first and second side edges.

Abstract
A display assembly particularly for the point-of-purchase field utilizes a light source to power the display. A solar cell is electrically connected, through a simple flashing circuit, to an array of light emitting diodes (LEDs). The diodes have a current usage of about 2 ma or less; e.g., they may be double heterojunction AlGaAs/GaAs material. The circuit has a current drain of about 0.1 ma or less. The solar cell may be mounted between an artificial light source (such as a fluorescent bulb) and a surrounding metal housing by sheet material having an undulating (e.g., accordion) configuration. Transparent UV inhibited plastic film tape may attach the solar cell to a central undulation of the sheet material while magnets strips attach side edges of the sheet material to a metal housing, so that the solar cell is in close proximity to (e.g., touches) the light source.

12. A point-of-purchase display assembly, comprising:
-
a solar cell; means for mounting said solar cell adjacent a light source; an array of light emitting diodes, each having a maximum current draw of about 2 ma, in a point-of-purchase display; circuit means for effecting flashing of said light emitting diodes having a current drain of less than about 0.1 ma, and consisting essentially of an integrated circuit, a capacitor, a resistor, and a transistor, all operatively electrically connected to each other; and electrical connector means for electrically connecting said circuitry means, array, and solar cell so that when said solar cell receives light from a light source, it flashes said light emitting diodes. - View Dependent Claims (13, 14)

15. An energy converting assembly in combination with an artificial light source mounting in a housing that is at least in part metal, said combination comprising:
-
a solar cell; a piece of sheet material having opposite first and second faces, and opposite first and second side edges, with an undulating configuration between said side edges; means for mounting said solar cell on said first face of said sheet material at an undulation approximately centrally between said first and second side edges; first and second magnet strips, said first strip mounted on said sheet material adjacent said first side edge, and said second strip mounted on said sheet material adjacent said second edge; and
said sheet material attached to said housing by said magnet strips with said undulation extending toward said light source, so that said solar cell is disposed in close proximity to said light source. - View Dependent Claims (16)
