A lighting system operating using a digital mirror as its operative device. The digital mirror is used to shape the light which is a passed through advanced optical devices in order to produce an output.

Electronically controlled stage lighting system

A moving light which has an electronic brake that automatically engages when power is released, to prevent movement of a moving head of a light whenever the power is released.

Pan and tilt servomotor with brake

An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter with three positions is placed between a light source and a DMD. The first position of the shutter is a mask, preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open, allowing substantially all the light to pass. The third position of the shutter is completely closed, blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs can be used in illumination devices without creating undesirable rectangular penumbras.

Illumination obscurement device

A hook clamp has surfaces allowing the clamp to be placed on a support and clamped thereto. The surfaces are such that the clamp can be placed on the support and its weight held by the support prior to tightening. The clamp has a built-in connector for supplying power to the lamp. The clamp has one or more fail-safe holes for securing the clamp to the support with a safety cable. The clamp also has one or more flanges that can be received by a separate mounting bracket, for mounting the clamp and any attached element during storage, staging, or when otherwise not being used.

Dual hook clamp

A super cooler device including a thermo electric cooler on a digital micro mirror device.

Super cooler for a heat producing device

A high output light source, such as a stage lighting luminaire, produces light along a path. The belt which drives a driven device is kept away from that path by passing it around the opposite side of the pulley.
