Abstract

An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

First claim

What is claimed is:

1. A method of retrofitting a HID lighting system with a LED lighting system, the method comprising:
physically disconnecting a motor of a cam motor assembly from a power source.

2. The method of claim 1 , further comprising changing the capacitance supplied to a power supply line.

3. The method of claim 2 , further comprising connecting a LED luminaire to the power supply line.

4. A method of retrofitting a HID lighting system with a LED lighting system, the method comprising:
disconnecting one or more ballasts from a power supply line; and
connecting one or more ballasts to a circuit including a power surge protection subcircuit.

5. The method of claim 4 , further comprising connecting one or more ballasts to a wire end bracket.

6. The method of claim 4 , further comprising removing one or more ballasts from an enclosure.

7. The method of claim 4 , further comprising connecting the one or more ballasts to a rectifying subcircuit.

8. The method of claim 7 , further comprising connecting the one or more ballasts to an open circuit protection subcircuit.

9. The method of claim 8 , further comprising connecting the one or more ballasts to output conditioning subcircuit.

10. The method of claim 4 , wherein the power surge protection subcircuit is configured to withstand at least a 10 kV surge measured via common mode, or at least a 5 kV surge measured via differential mode.

11. The method of claim 9 , wherein a plurality of components of the power surge protection subcircuit, the rectifying subcircuit, the open circuit protection subcircuit, and the output conditioning subcircuit are connected to each other in parallel.

12. A method for creating uplight, the method comprising:
attaching a lens, an optic, or a diffuser to a free end of a visor of a light source; and
redirecting light at an upward trajectory relative to the light source.

13. The method of claim 12 , further comprising aiming a collimated light beam at a portion of the lens, the optic, or the diffuser.

14. The method of claim 13 , further comprising aiming a collimated light beam from a third row of LEDs from a top of a LED array.

15. The method of claim 12 , further comprising moving the lens, the optic, or the diffuser relative to the light source to adjust the redirected light.
