Document Type and Number:
WIPO Patent Application WO/2015/192864
Kind Code:
A4
Abstract:
Apparatus and method embedding a camera in a street light includes structure and/or function whereby the street light, comprising has a first compartment having an LED array configured to illuminate an area beneath the street light. A second compartment is coupled to the first compartment and has a camera directed toward the area beneath the street light. The second compartment has a window covering the camera such that the camera can receive light from area beneath the street light, but passers-by do not see the camera. A third compartment is coupled to the second compartment and is configured to attach the street light to a vertical support. A passive air channel is disposed between the first compartment and the second compartment, and is configured to direct air from beneath the street light to the top of the street light. Preferably, the power supply for the LED array is disposed in a compartment different that the first compartment. An anti-glare device is preferably mounted to a bottom of at least one of the first compartment and the second compartment, and is configured to shield the camera from light glare and/or reflections from the LED array.

an LED light compartment (2) having an array of LED lights (3) disposed to direct light to an area to be observed;

a camera compartment (4) coupled to but thermally insulated from the LED light compartment, the camera compartment having a camera (8) with a lens that is (i) disposed vertically below said array of LED lights, and (ii) disposed to capture an image from the area to be observed;

a power supply compartment (5) coupled to at least one of the LED light compartment and the camera compartment, the power supply compartment configured to support a power supply (30) of said array of LED lights; and

a passive cooling air channel (12) disposed between the LED light compartment and the camera compartment, enhancing thermal insulation therebetween, each of the LED compartment and the camera compartment being weatherproofed, at least with respect to the air channel.

9. The LED street light according to Claim 8, wherein the cooling air channel slopes at an angle from a bottom of the streetlight to a top thereof.

10. The LED street light according to Claim 8, further comprising a shield device vertically oriented between the LED light compartment and the camera compartment, and configured to (i) block light from the array of LED lights from reaching the camera lens, and (ii) direct air into the cooling air channel.

11. The LED street light according to Claim 8, wherein the camera compartment is disposed between the LED light compartment and the power supply compartment, and further comprising a light pole connection mechanism configured to couple the LED streetlight to a vertical light pole.

12. The LED street light according to Claim 8, further comprising a light control unit (28) disposed in at least one of the camera compartment and the power supply compartment.

13. The LED street light according to Claim 8, wherein the power supply compartment is heavier than the camera compartment, and wherein the camera

compartment is heavier than the LED light compartment.

14. The LED street light according to Claim 8, further comprising at least one antenna (9) configured to (i) receive commands from a remote center (94), and (ii) transmit plural captured images from the camera to the remote center.
