Deterrent device attachment having light source with thermal management
First Claim
Patent Images
1. A deterrent device attachment comprising:
- a housing having an open area defined by area walls and an end wall having a segment through which light can pass;
a support board having a metal layer with a first bend between a first end portion and a support portion;
a light source that generates light and heat when energized is positioned in the support portion;
a drive circuit adapted to controllably energize the light source; and
,a drive board positioned orthogonal to and above the light source board wherein the drive circuit is provided on the drive board;
wherein the support board is positioned at least in part between at least two of the area walls with the support portion arranged to direct light generated by the light source toward the opening and with the first end portion extending away from the segment at least in part in a direction along one of the area walls with the metal layer providing a first boundary free area along which the heat can spread from the light source and be dissipated.

13. A deterrent device attachment comprising:
-
a housing having an open area defined by area walls and an end wall having a segment through which light can pass; a support board having a metal layer with a first bend between a first end portion and a support portion; a light source that generates light and heat when energized is positioned in the support portion; a drive circuit adapted to controllably energize the light source; and
,a drive board positioned orthogonal to and above the light source board wherein the drive circuit is provided on the drive board; wherein the support board is positioned at least in part between at least two of the area walls with the support portion arranged to direct light generated by the light source toward the opening and with the first end portion extending away from the segment at least in part in a direction along one of the area walls with the metal layer providing a first boundary free area along which the heat can spread from the light source and be dissipated and wherein the drive board has an opening to receive a tab portion of the support board having electrical paths thereon that are adapted to allow energy to flow from the drive circuit to the light source and wherein the drive circuit has terminals positioned proximate to the contacts when the tab portion of the support board is positioned in the opening. - View Dependent Claims (14, 15, 16, 17, 19, 20, 21, 22, 23, 24)
