Abstract

A luminaire can include a power supply that receives AC mains power from a power source and delivers intermediate power, and can also include a lumen control module coupled to the power supply, where the lumen control module receives the intermediate power from the power source. The lumen control module can include at least one first switch that has multiple positions, and multiple resistors coupled to the at least one first switch, where each position of the at least one first switch corresponds to a resistance of the resistors, where the intermediate power received by the resistors is translated to a current level of a plurality of current levels based on the resistance. The luminaire can also include at least one light source coupled to the lumen control module, where the at least one light source emits a lumen output based on the current level received from the lumen control module.

First claim

What is claimed is:

1. A luminaire comprising:
a power supply that receives AC mains power from a power source and delivers intermediate power; and
a lumen control module coupled to the power supply, wherein the lumen control module receives the intermediate power from the power source, wherein the lumen control module comprises:
at least one first switch that has multiple positions; and
a plurality of resistors coupled to the at least one first switch, wherein each position of the at least one first switch corresponds to a resistance of the plurality of resistors, wherein the intermediate power received by the plurality of resistors is translated to a current level of a plurality of current levels based on the resistance; and

at least one light source coupled to the lumen control module, wherein the at least one light source emits a lumen output based on the current level received from the lumen control module.

2. The luminaire of claim 1 , wherein the lumen control module further comprises a controller.

3. The luminaire of claim 2 , wherein the controller of the lumen control module selects a position of the multiple positions of the at least one first switch.

4. The luminaire of claim 3 , wherein the controller comprises a transceiver, wherein the transceiver receives instructions from a user, wherein the instructions determine the position of the at least one first switch.

5. The luminaire of claim 4 , wherein the instructions are received from a remote control.

6. The luminaire of claim 1 , further comprising:
a second switch disposed in parallel with the at least one first switch between the power supply and the plurality of resistors.

7. The luminaire of claim 1 , wherein the at least one first switch is a physical switch that is manipulated by a user to select the position of the at least one switch.

8. The luminaire of claim 7 , wherein the at least one first switch is disposed within a housing of the luminaire.

9. The luminaire of claim 8 , wherein the housing has an access mechanism that allows the user to access the at least one first switch without disassembling the luminaire.

10. The luminaire of claim 7 , wherein the at least one first switch is disposed on a housing of the luminaire.

11. The luminaire of claim 10 , wherein the at least one first switch is removably coupled to the housing.

12. The luminaire of claim 7 , wherein the at least one first switch is inaccessible when the luminaire is installed.

13. A lumen control module for controlling lumens output by light sources of a luminaire, the lumen control module comprising:
at least one switch having a plurality of positions, and
a plurality of resistors coupled to the at least one switch and having a plurality of resistances, wherein each position of the at least one switch corresponds to a resistance of the plurality of resistors,
wherein the at least one switch is configured to receive power from a power supply of the luminaire,
wherein the plurality of resistors are configured to deliver, using the power received by the at least one switch, a current level of a plurality of current levels to the light sources of the luminaire,
wherein the current level is based on the resistance of the plurality of resistors.

14. The lumen control module of claim 13 , further comprising:
a controller coupled to the at least one switch, wherein the controller controls the plurality of positions of the at least one switch.

15. The lumen control module of claim 14 , further comprising:
a transceiver coupled to the controller, wherein the transceiver is configured to receive instructions for selecting the lumens output by the light sources of the luminaire.

16. The lumen control module of claim 15 , wherein the transceiver communicates using wireless technology.

17. The lumen control module of claim 14 , further comprising:
a memory storing a plurality of instructions; and
a hardware processor coupled to the memory, wherein the hardware processor executes the plurality of instructions for the controller.

18. The lumen control module of claim 13 , wherein the plurality of resistors comprises a plurality of discrete resistors coupled in parallel to each other and in series with the at least one switch.

19. The lumen control module of claim 13 , wherein a first resistor and a second resistor of the plurality of resistors are connected in series with each other, wherein a third resistor of the plurality of resistors is connected in parallel with the first resistor.

20. The lumen control module of claim 13 , wherein at least one resistor of the plurality of resistors is a variable resistor.
