Abstract
A garden light 10 having a body (11) with a post (12), the lower end of which is provided with a spike (13). The upper end of the post (11) receives a lens assembly (12). Secured to the lens assembly (12) is a cap assembly (24) that has three LEDs that are activated to produce a varying color light.
Claims35
A lighting device to produce light, said device including:
- a base;
- a lens mounted on the base and generally enclosing a chamber;
- a circuit having at least one lamp to produce a light, the lamp being mounted to direct light into said chamber, connections for at least one rechargeable battery to power the circuit and a solar cell exposed to said chamber so as to receive light passing through said lens and operatively associated with the connections to charge the battery, and a primary switch operable to control said circuit;
- a battery compartment including a cavity to receive said battery and having said connections;
- a closure member attached to said compartment but movable relative thereto to expose said cavity to provide for insertion of said battery;
- and wherein
- said switch is exposed to said cavity so that upon movement of said closure member to expose said cavity, a user has access to said switch to operate the switch.

A lighting device to produce light of varying colour, said device comprising:
- a lens generally enclosing a chamber;
- a circuit including:
- at least two lamps of different colours to produce a desired colour including a varying colour, the lamps being mounted to direct light into said chamber;
- connections for at least one rechargeable battery to power the circuit;
- a solar cell mounted on a surface so as to be exposed to light and operatively associated with the connections to charge the battery;
- a light sub-circuit having an integrated circuit for controlling said lamps, and a selection switch, said selection switch being connected to said integrated circuit and operable to select a desired fixed colour;
- and
- a volatile memory retained for a period of time and associated with said integrated circuit, said memory causing operation of said circuit to produce said desired fixed colour.

A lighting device to produce light of varying color, said device including:
- a lens;
- a circuit having
- at least two lamps of different colors mounted to direct light through said lens,
- an activation sub-circuit to provide power to said lamps only at low light levels, and
- a light sub-circuit to independently control delivery of power to each of said lamps so as to vary intensity of light emitted over time to produce a continuous color changing cycle,
- connections for at least one rechargeable battery to power said circuit, and
- at least one solar cell mounted so as to be exposed to light and operatively associated with said connections to charge said battery;
- and a spike for positioning said connections above a ground surface.
