Projection system

Disclosed herein is a housing for containing a laser and lens for use in a laser light projection display, and a lighting device incorporating the laser within the housing and other light sources, such as light-emitting diodes (LEDs). The laser and lens are secured within a housing and maintain a spaced distance using a spacer. The lighting device uses the laser in combination with LEDs arrayed around the laser to provide a dual source light.

Laser housing and dual light source lighting device with laser

The present disclosure is directed to projection devices that can project patterned light of different colors. In one implementation, the projection device can include a housing, within which reside multiple components. These components can include light emitting diodes (LEDs), a parabolic mirror reflector, a sinusoidal lenticular diffuser, and multiple spatial filters. The multiple LEDs can be provided in at least two distinct colors. The parabolic mirror reflector can be arranged to collimate light received from the multiple LEDs. The sinusoidal lenticular diffuser can be positioned at an output of the parabolic mirror reflector and arranged to diffuse the collimated light. The spatial filters can be arranged to diffuse the diffused and collimated light received from the sinusoidal lenticular diffuser. An imaging lens can be coupled to the housing and arranged to magnify the diffused light received from the spatial filters and display a cloud-like effect on a first surface.

Optical projection device

Embodiments of invention are directed to a lighting device for use in accent lighting applications. In one embodiment, the lighting device includes a coherent light source, such as a laser, and a diffractive optical element. The diffractive optical element may be, for example, a holographic optical element. The lighting device may be adapted to retrofit into a pre-existing light fixture. In one application, the lighting device may project a static or movable star field and/or static or movable clouds.

Lighting device for accent lighting and method

An improved particle effect projector is disclosed that reduces the energy density of a laser beam projected through a movie theater or other entertainment venue, comprising an F-theta lens, a beam expander and a beam focuser with a long focal length that approximates the distance between the particle effect projector and the movie screen or other surface onto which the particle effect beam is being projected.

A laser landscape lighting apparatus for use in accent lighting applications for landscapes and outdoor venues. In one embodiment, the laser landscape lighting apparatus includes a coherent light source in combination with a diffractive optical element and optionally a diffraction grating wheel. The diffractive optical element may be, for example, a holographic optical element. In some embodiments, the laser landscape lighting apparatus includes a temperature-controlled integral derivative system. In one application, the laser landscape lighting apparatus may project a static or movable star field.

Laser lighting apparatus with heatsink housing

A projection apparatus for generating a moving star field and a cloud-like effect comprises a means for generating a cloud-like effect using at least one non-coherent light source, a means for generating a moving star field using at least one coherent light source and a means for regulating and supplying electric power. The means for generating cloud-like effect using at least one non-coherent light source comprises at least one pair of condenser lenses and an interferential filter wheel rotated by a motor, disposed between at least one pair of condenser lenses. The means for generating the moving star field using a coherent light source comprises a grating wheel rotated by a motor and a diffractive optical element disposed between the at least one coherent light source and the grating wheel.

The present invention involves a system and method for detecting a graffiti-making act such as the spray of a spray paint can, the writing with a felt-marker pen on a surface, and the scratching with an abrasive instrument on a surface. The system includes one or more sensors adapted to sense the graffiti-making act and transmit a signal representative of the graffiti-making act, and a base unit including electronics adapted to process the signal and determined whether the signal represents a graffiti-making act, and a communication device coupled to the electronics and adapted to communicate to one or more entities that a graffiti-making act has been detected. The method includes sonically detecting the graffiti-making act, and initiating an alarm indicating that the graffiti-making act took place.
