System and method for horticultural lighting
A method and apparatus are described herein for capturing images of plants using a broad spectrum camera while illuminating the plants with specific light wavelengths from light sources such as light emitting diodes (LEDs). A first light source may be activated, wherein the first light source emits light having a first spectrum toward a bed of a plurality of plants. On a condition that the first light source is activated, a first image of the bed of the plurality of plants may be captured with a broad spectrum camera. A second light source may be activated, wherein the second light source emits light having a second spectrum toward the bed of the plurality of plants. On a condition that the second light source is activated, a second image of the bed of the plurality of plants may be captured with the broad spectrum camera.
1. A method comprising:
activating a first light source that emits light having a first spectrum toward a bed of a plurality of plants;
capturing a first image of the bed of the plurality of plants with a broad spectrum camera on a condition that the first light source is activated and a second light source that emits light having a second spectrum different than the first spectrum, towards the bed of a plurality of plants, is deactivated;
activating the second light source; and
on a condition that the second light source is activated, capturing a second image of the bed of the plurality of plants with the broad spectrum camera if the second light source is activated and if the first light source is deactivated.
2. The method of claim 1 , wherein the first light source includes a blue light emitting LED and a red light emitting LED.
3. The method of claim 1 , wherein the second light source includes an LED that emits white light.
4. The method of claim 1 , wherein the first image and second image are stored in a memory device and transmitted over a network.
5. A system comprising:
a first light source configured to emit light having a first spectrum toward a bed of a plurality of plants;
a second light source configured to emit light having a second spectrum toward the bed of the plurality of plants;
a broad spectrum camera configured to capture a first image of the bed of the plurality of plants if the first light source is activated and the second light source is deactivated; and
the broad spectrum camera further configured to capture a second image of the bed of the plurality of plants if the second light source is activated and the first light source is deactivated.
6. The system of claim 5 , wherein the first spectrum is different from the second spectrum.
7. The system of claim 5 , wherein the first light source includes a blue light emitting LED and a red light emitting LED.
8. The system of claim 5 , wherein the second light source includes an LED that emits white light.
9. The system of claim 5 , further comprising:
a third light source configured to emit light having a third spectrum toward the bed of the plurality of plants; and
the broad spectrum camera further configured to capture a third image of the bed of the plurality of plants on a condition that the third light source is activated.
10. The system of claim 5 , further comprising:
a sensor configured to detect occupancy of a location near the bed of the plurality of plants;
a processor configured to activate the first light source in response to detection of non-occupied space; and
the processor further configured to activate the second light source in response to detection of occupied space.
11. The system of claim 5 , wherein the first light source, the second light source, and the broad spectrum camera are mounted on a printed circuit board with a communication interface to a network.
12. The system of claim 5 , wherein the broad spectrum camera is mounted such that it does not absorb light from the first light source or second light source.
13. A method comprising:
detecting for occupancy in a location, wherein occupancy is detected via motion in the location;
on a condition that occupancy is not detected, activating a first light source such that the first light source emits light toward a bed of a plurality of plants from a blue light emitting LED and a red light emitting LED; and
on a condition that occupancy is detected, activating a second light source such that the second light source emits light toward the bed of the plurality of plants from a white light emitting LED.
14. The method of claim 13 , further comprising:
on a condition that the first light source is activated, capturing a first image of the bed of the plurality of plants with a broad spectrum camera.
15. The method of claim 14 , further comprising:
on a condition that the second light source is activated, capturing a second image of the bed of the plurality of plants with the broad spectrum camera.
16. The method of claim 13 , further comprising:
detecting a status change in the location.
17. The method of claim 16 , further comprising:
on a condition that the status change is not detected, activating the first light source; and
on a condition that the status change is detected, activating the second light source.
18. The method of claim 17 , wherein the status change is reception of a wireless signal.
19. The method of claim 17 , wherein the status change is a change in temperature or humidity.
