A lens system for LED based light fixtures having a substantially coplanar array of LED's with a requirement for a wide angle of illumination. And in particular, light fixtures comprising LED lights used in low bay applications.

An optical component includes a support member having a through-hole, a second light-transmissive member disposed inside the through-hole, and having a light incidence face, a light emission face, and an outer peripheral side surface, and at least one functional film selected from a group consisting of a short pass filter, a long pass filter, and a heat dissipation member and disposed on a surface of the second light-transmissive member.

The present invention provides an artificial candle includes a hollow cylinder, an electric wire, and a light bulb. The light bulb includes a light source with a long strip shape, a cup sleeved on and fixed to the electric wire at a position near the first end of the electric wire, an outer cover covered on the cup, and an inner cover sleeved on the light source and defining a receiving space with the cup for receiving a part of the light source and the second end of the electric wire. The light transmitted of the inner cover is less than that of the outer cover and that of the cup. The inner cover is configured for reflecting light emitted from the part, received in the receiving space, of the light source towards the wire holder and an exposed part of the electric wire. A simulating effect of flame is improved.

Provided in this disclosure is an apparatus for marking an implement, such as a snow plow. An elongated tubular member retains an illuminated member such a high lumen LED lighting element mounted substantially adjacent to the bottom end of the elongated tubular member and configured to shine light through the interior of the elongated tubular member toward the top end. Conductor wiring connects a source of electrical energy to the LED. An enclosing cap includes a crimped end portion secured to the bottom end of the elongated tubular member. A cylindrical end portion has a hollow interior for admitting the conductor wiring for connection to the source of electrical energy. A mounting bracket can include a first mounting surface and a second mounting surface, formed together to support the illuminated member.

Disclosed is an ultraviolet ray emitting diode lighting device. The disclosed invention comprises: an ultraviolet ray emitting diode for emitting ultraviolet rays; a substrate on which an ultraviolet ray emitting diode is mounted; a base on which a space for accommodating the substrate is formed and an electrode pin electrically connected to the substrate is installed; and a cover, which is provided to surround the ultraviolet ray emitting diode and the substrate and is coupled to the base, wherein the base includes a support guide fitted in the substrate to support the substrate on the base so as to restrict movement of the substrate.

Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.

An illumination device system includes: an illumination device including an engaging portion configured to engage with an illumination device support base, a main body portion, a light emitting portion configured to swing around a turning axis in relation to the main body portion, and a cable extending from the main body portion; and a diffuser, and the diffuser swings around the turning axis between an advanced position positioned in front of the light emitting portion and a withdrawn position withdrawn from the front of the light emitting portion, and includes a first locking portion configured to engage with the illumination device support base and holds the diffuser at the advanced position, and a second locking portion configured to engage with the cable and holds the diffuser at the withdrawn position.

A show effect system may include a plasma tube configured to generate an electric arc within the plasma tube and a light strip extending along the plasma tube. The light strip may include a plurality of light emitters configured to output light through the plasma tube and backlight the electric arc generated by the plasma tube.

A lighting device for a motor vehicle having a light source, a light guide with an entrance surface, and a hologram disposed on or in the light guide. The lighting device is configured such that light emanating from the light source enters the entrance surface of the light guide and interacts with the hologram so that an image stored in the hologram is reconstructed and is visible to an observer of the lighting device. The light guide has a first exit surface and a second exit surface. The lighting device is configured such that light that has interacted with the hologram exits through the first exit surface and that light that has not interacted with the hologram exits through the second exit surface.

A method of lamp assembly that etching a glass tube body to increase a texture of the surface of the sidewall of the glass tube body, the sidewall of the glass tube body enclosing a hollow interior; and positioning a circuit board including a plurality of light emitting diodes (LEDs) within the hollow interior of the glass tube, wherein the increase in the texture of the surface increases the light diffusivity of the glass tube body.
