Filed:

Appl. No.:

09/821307

Inventors:

Chi Yu - Brooklyn NY
Dale Marks - Houston TX

Assignee:

Lowel-Light Manufacturing, Inc. - Brooklyn NY

International Classification:

F21S 808

US Classification:

362418, 362401, 362410

Abstract:

A support bracket for a device, such as a light, has a swivel mount provided at one end of a bent support arm, the other end of which can be held in a conventional stand. The support arm is shaped to position a light or other device connected to the swivel mount so that the center of gravity of the light is over the vertical axis of the stand. Positioning the center of gravity over the vertical axis of the stand is essential, so that the need for counterweights, counterbalances and ballasts is reduced in order to keep the light stable when mounted on the connector bracket held by a stand. When the center of gravity of the light is also aligned with a horizontal axis of the swivel mount bracket, the light can be pivoted and rotated on the bracket without affecting the balance. The tilt bracket is preferably used with portable lights so that the amount and weight of equipment needed to mount the light is reduced.
