A projection device with dynamic light effect is provided, which includes at least one LED light source, a condensing lens, at least one external projection mono-convex lens, and further includes at least one filter. The filter is located between the condensing lens and the external projection mono-convex lens, an out-light surface of the condensing lens is provided with a first ripple. An upper and/or a lower surface of the filter are provided with a second ripple; being refracted by an interference pattern on the first ripple through the condensing lens, emitted light corresponding to the interference pattern on the first ripple is formed. Then, the light passes through the filter and undergoes two refractions. The light is refracted by the interference pattern on the second ripple, resulting in a refraction effect of the interference pattern superimposed on the first ripple and second ripple.

A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

A mirror assembly includes a mirrored surface, at least one frosted edge disposed along a side of the mirror surface, a fresnel lens, and a light source configured to generate light. The fresnel lens is configured to refract a primary light path of the generated light, the refracted light traveling through the at least one frosted edge.

The broad view headlamp includes a plurality of light sources that illuminate an area in front of the headlamp, an area adjacent to each side of the headlamp, and an area below the headlamp. The headlamp includes a number of lighting modes, such that any one of the light sources can be operated individually or in combination with any one or more of the remaining light sources. The headlamp housing has multiple lighting compartments, each having one or more light sources disposed therein. Each compartment includes an optical lens. The various light sources, together with the optical lenses, allow the headlamp to illuminate a view area extending to, at least, the outer boundaries of the far peripheral vision of the human eye, i.e., 110 degrees to the right and left of center. Thus, the total combined view area illuminated by the headlamp is at least 220 degrees.

A system for use with a billiards table may include addressable multicolor LED strips, a controller and a user device. The controller may be configured to send signals through the LED strips to control which one or more pixels are activated and one or more colors of light to be produced by corresponding one or more LEDs for the one or more activated pixels. The user device may communicate with the controller and may implement a program configured to enable a user of the user device to send lighting commands to the controller during gameplay. The lighting commands may indicate user-desired changes to lighting provided by the addressable multi-color LED strips. The controller may send corresponding signals to the addressable multi-color LED light strips to implement the changes to the lighting.

A light fixture assembly includes a housing having an interior surface, a ballast mounted on the interior surface of the housing, a first reflector releasably coupled to the interior surface of the housing, the ballast being substantially enclosed between the housing and the first reflector when the first reflector is in a first, closed position and being exposed when the first reflector is in a second, open position spaced from at least a portion of the interior surface, a lens releasably coupled to the housing, the first reflector being substantially enclosed between the lens and the housing when the lens is in a first, closed position and substantially exposed when the lens is in a second, open position. This construction provides relatively easy and quick access to the ballast for replacement and from below the fixture if it is mounted in or on the ceiling.

A luminaire includes a body including a lighting compartment and a bezel rim around at least a portion of a perimeter of the body. The luminaire also includes clamping plates that extend a length of the luminaire. As the clamping plates are secured in a lighting compartment of the luminaire, they provide a clamping force to secure an LED circuit board in the lighting compartment. A base of the lighting compartment may also serve as a heatsink for the LED circuit board. A low-profile luminaire according to such features is also provided.

A light emitting diode (LED) circuit board includes a power input configured to supply power, a driving circuit configured to convert power, and a light emitting circuit configured to generate light. The power input is configured to supply power to the driving circuit. The driving circuit is configured to provide proper power to the light emitting circuit. The light emitting circuit is configured to generate light with the power provided by the driving circuit. An LED circuit board including a driving circuit, a light emitting circuit, and a plurality of semiconductor switches electrically connected between the driving circuit and the light emitting circuit is also provided. Each of the plurality of semiconductor switches is configured to electrically connect and electrically disconnect power from the driving circuit to the light emitting circuit.

A modular luminaire which uses LED light sources. The basic frame comprises two end pieces compressed together by through bolts. At least one elongated heat sink is compressed between the end pieces. Each heat sink may bear a plurality of LEDs mounted on a printed circuit board which may have an integral metallic backplate, and is installed on one of the heat sinks with a layer of heat conductive grease therebetween. The heat sinks have fins projecting in three directions, the fourth direction being accounted for by the LEDs, and are rotatable about their longitudinal axes to adjust direction of light propagation. The heat sinks are arrayed in an arc, so that the outside heat sinks shield observers from direct glare from opposed heat sinks. Heat sinks may be extruded to form cooling fins and slots which may receive fasteners such as screws.

The invention discloses a tactical flashlight with camera function, which comprises a flashlight component, wherein the flashlight component comprises a main shell, a lamp component and a camera component located above the lamp component are arranged inside the main shell, the lamp component comprises a lamp panel and LEDs arranged on one side of the lamp panel, a lamp cup for covering the LEDs is also arranged on one side of the lamp panel, and the camera component comprises a lens mount. The camera function is integrated into the flashlight with laser aiming function, the flashlight is installed on outdoor equipment to record the situation in front of the flashlight as well as the actions of holding gun for self-defense and go hunting in real time, buttons are located at the tail of the main shell, and a storage slot is used to store a buckle.
