The utility model discloses a laser snowfall light, which comprises a laser module, a drive motor and a cambered-surface multi-directional reflecting mirror, wherein the drive motor drives the cambered-surface multi-directional reflecting mirror to rotate, and a light beam emitted by the laser module is irradiated on a surface of the cambered-surface multi-directional reflecting mirror. The light beam emitted by the laser module of the scheme is irradiated on the cambered-surface multi-directional reflecting mirror to exhibit the effect of snowflakes flying all over the sky, and then the cambered-surface multi-directional reflecting mirror is rotated by the drive motor to exhibit the effect of snowflakes falling from the sky.

A bolt locking structure for a waterproof LED lamp contains: a first casing and a second casing. The first casing includes multiple first protrusions and multiple first recesses which are arranged on each of four peripheral walls thereof respectively. The second casing includes multiple second protrusions and multiple second recesses which are arranged on each of four peripheral walls thereof respectively. The multiple first protrusions retain with the multiple second recesses, and the multiple first recesses retain with the multiple second protrusions. Multiple through holes are coaxial and form on each peripheral wall of each of the first casing and the second casing respectively, wherein each of the multiple through holes passes through each of the multiple first protrusions and the multiple second protrusions, such that each of multiple connection bolts inserts into the multiple through holes, thus locking the first casing and the second casing together.

A sensor support for use with a lighting refractor includes a housing defining an interior cavity configured to receive and support a sensor for sensing at least one of motion or light. The sensor support further includes a locking structure operatively associated with the housing and configured to selectively attach the housing to a peripheral portion of a lighting refractor, and an aperture in the housing and arranged to expose the sensor to an environment around the lighting refractor. Sensor and lighting unit assemblies are also disclosed. A sensor assembly includes the sensor support and a sensor configured to sense at least one of motion or light. A lighting unit assembly includes the sensor support and a lighting unit having a refractor with a peripheral portion.

A luminaire includes a rail assembly including a first rail and a second rail. A light bar assembly is releasably connected to the rail assembly extending between the first rail and the second rail. The light bar assembly includes a light bar and a light emitter connected to the light bar. A control component assembly is releasably connected to the rail assembly extending between the first rail and the second rail and operatively connected to the light bar assembly. The control component assembly includes a control component housing containing at least one control component.

An LED filament light including a bulb, a support bar, at least two electrode wires and at least two LED filament strips. Each LED filament strip including a base, an LED chip is set on the base and an electrode is fixed at both ends of the base. One end of the electrode is electrically connected with an LED chip on the base, the other end of the electrode is electrically connected with an electrode of another LED filament or electrically connected to one end of the electrode wires so that the support bar is fixed to the bulb, and the other end is connected with at least one. As the support bar is set to replace the existing LED filament light core and metal wire, and creatively the LED filament electrodes directly is connected to each other.

A multifunctional LED bulb comprises a lamp base, a light-transmitting bulb shell, a driving power supply, electric lead wires, a stem, at least one LED light source and a support column, wherein the tail of the light-transmitting bulb shell is fixedly connected with the lamp base; the driving power supply is located in the lamp base, and the LED light sources and the support column are wrapped in an inner cavity of the light-transmitting bulb shell; the light-transmitting bulb shell is sealed by the lower portion of the stem which is of a hollow structure, an exhaust pipe is arranged in the stem, and a hole is formed in the joint of the upper end of the exhaust pipe and the stem. The multifunctional LED bulb is good in light transmission performance, has the same light-emitting mode, size and shape as ordinary incandescent bulbs, and is attractive in appearance, simple in structure, capable of saving energy, environmentally friendly, good in heat dissipation effect, capable of emitting light in all directions, and good in light-emitting effect.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.

In accordance with at least one example embodiments, a swivel lamp may include a primary housing, a lamp housing enclosing at least one light emitting member at a first end of the lamp housing and at least one light emitting member at a second end of the lamp housing, and a switch configured to control power to the light emitting members.
