US Patent:

6554459, Apr 29, 2003
Filed:

Mar 28, 2001
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.

US Patent:

61081949, Aug 22, 2000
Filed:

Mar 10, 1999
Appl. No.:

9/265785
Inventors:

Marvin Seligman - Teaneck NJ
Chi Yu - Brooklyn NY
Assignee:

Lowel-Light Manufacturing, Inc. - Brooklyn NY
International Classification:

H02B 100
US Classification:

361600
Abstract:

An electronics casing is formed from interlocking upper, lower and side panels and a pair of end plates. Grooves are formed in the outer surface of the lower panel for mounting the casing on the legs or struts of tripods or other lighting supports. The weight of the casing helps counter-balance lighting elements supported on the tripod and holds the casing in place. Multiple casings may be connected together using dovetail tongue and groove connectors on the sides of the casing.

US Patent:

61765988, Jan 23, 2001
Filed:

Apr 16, 1999
Appl. No.:

9/293412
Inventors:

Marvin Seligman - Teaneck NJ
Chi Yu - Brooklyn NY
Assignee:

Lowel-Light Manufacturing, Inc. - Brooklyn NY
International Classification:

F21V 106
US Classification:

362352
Abstract:

A light fixture for receiving commercially available reflectors or diffusers having flexible walls and a plurality of flexible struts, has a housing with a socket for receiving a lamp or lamps. A power connection is provided for supplying electrical power to the socket and a plurality of receivers are connected to the housing, each for receiving a free end of a strut. A mount is connected to the housing for mounting the housing to a stand or tripod or other appropriate support. Each of the receivers which are preferably in the form of tubes or blind bores, are positioned so that the free end of each strut must be bent into a braced position and inserted into a receiver. This deploys the flexible wall of the reflector or diffuser into its open reflecting position.
