1. An outdoor illumination system comprising:
- (a) an electrical lamp illumination means being operable in a dimmed mode and a full bright mode and being contained in a light fixture;
(b) electrical power supply means connected in circuit to said electrical lamp illumination means;
(c) means mounted adjacent said fixture for sensing when ambient light intensity is higher than a preselected level and for de-energizing the electrical lamp at said level;
(d) means mounted adjacent said fixture for inputting and storing data concerning a preselected daily chronological period inside of which period the electrical lamp illuminations means should be dimmed; and
(e) bilateral switching means for reducing electrical power to the electrical lamp illumination means based on instructions from said means for inputting and storing data concerning a preselected daily chronological period as to whether time is within said preselected chronological period, such that said instructions will result in the electrical lamp illumination means being operated in its dimmed mode unless said lamp illumination means is de-energized by said means for sensing when ambient light intensity is higher than a preselected level as a result of ambient light intensity being higher than said preselected level.

Abstract
An outdoor illumination system having a dimmed and bright mode and is a moprocessor-based, dimming photocontrol unit for reducing the energy consumed by single, outdoor high intensity discharge light fixtures by combining a dimming and photocontrol circuit into one unit which plugs directly into the existing photocontrol jack located on most outdoor high intensity discharge fixtures.

19. A method for operating an outdoor illumination system comprising:
-
(a) providing an electrical lamp illumination means being operable in a dimmed mode and a full bright mode and being contained in a light fixture; (b) providing an electrical power supply means connected in circuit to said electrical lamp illumination means; (c) sensing by means mounted adjacent said fixture when ambient light intensity is higher than a preselected level and de-energizing the electrical lamp at said level; (d) inputting and storing data by means mounted adjacent said fixture concerning a preselected daily chronological period inside of which period the electrical lamp illuminations means should be dimmed; and (e) providing bilateral switching means for reducing electrical power to the electrical lamp illumination means based on instructions from means for inputting and storing data concerning a preselected chronological period as to whether time is within said preselected chronological period, such that said instructions will result in the electrical lamp illumination means being operated in its dimmed mode unless said lamp illumination means is de-energized by said means for sensing when ambient light intensity is higher than a preselected level as a result of ambient light intensity being higher than said preselected level. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
