1. A lamp system comprising:
- a lamp,a first power source for the lamp;
a second power source for the lamp;
a controller configured for illuminating the lamp from either the first power source, or a combination of power from the first and second power source, the proportion of power from the first power source relative to the proportion of power from the second power source determined by the level of power available from the first power source.

Abstract
A hybrid lamp assembly according to the present invention comprises several different primary components, specifically, a lamp, lamp housing, and controller. The lamp may be powered by either of two different alternative power sources, a solar panel and grid power, and a combination of power from the solar panel and the grid power. An indicator lamp houses two LEDs that indicate the status of the lamp and which power sources are providing current to the lamp, and the relative amount of current being supplied. The hybrid lamp assembly may optionally include an emergency backup battery system to power the lamp when no grid power is available.

12. A lamp system comprising:
-
a lamp, a solar panel defining a first power source; a grid power source defining a second power source; a controller electrically connected to each of the first and second power sources and capable of powering the lamp in a first mode defined when power is available from the second power source, and wherein in the first mode the lamp may be illuminated by; (a) power solely from the first power source; (b) power from both the first and second power sources; and (c) power solely from the second power source; and wherein when the lamp is powered from both the first and second power sources, the controller determines the proportion of power from the first power source relative to the total combined power from the first and second power sources and provides a visual indication of said proportion of power. - View Dependent Claims (13, 14, 15)

16. A method of powering a lamp system, comprising the steps of:
-
(a) providing a lamp; (b) connecting the lamp to a controller; (c) connecting a first power source to the controller; (d) connecting a second power source to the controller; and (e) determining whether power is available from the second power source and if power is available from the second power source, determining the amount of power available from the first power source, and if the amount of power from the first power source is sufficient to illuminate the lamp, illuminating the lamp solely from the first power source, and if the amount of power from the first power source is insufficient to illuminate the lamp, illuminating the lamp with a combination of power from first and second power sources. - View Dependent Claims (17, 18, 19, 20)
