The silicone optical array has a plurality of silicone optics formed in the silicone optical array. The silicone optical array is located so as to cover one side of the substrate and the plurality of light emitting sources. The silicone optical array may further include a silicone mat and a plurality of silicone optics formed in the silicone mat and being arranged in an array corresponding to the array of light emitting sources.

The present disclosure provides a lamp holder rotating assembly, comprising a foundation support, an inserted rod, and a rotating head. The foundation support defines a locating slot. The inserted rod comprises a head end and a tail end coupled to the head end. The rotating head defines a groove. The inserted rod is rotatably mounted on the foundation support. The tail end passes through the locating slot. The head end passes through the groove of the rotating head. The head end rotates in the groove along a first direction which causes the tail end rotating in the locating slot along a second direction opposite to the first direction. The present disclosure further provides an illuminating apparatus.

The present invention provides a patch LED light bulb comprising a lampshade and a base. It further comprises a light source baseboard and a power supply board which are disposed inside the lampshade and electrically connected to each other. The light source baseboard is pasted or soldered with more than one LED chip. The lampshade comprises a cover body and an assembly portion integrally connected to the cover body. The assembly portion is inserted into the base. A limiting slot is provided on the assembly portion. A positioning slot is provided on the light source baseboard. The power supply board abuts against the light source baseboard and is perpendicular to the light source baseboard. The power supply board is integrally connected with a limiting protrusion for inserting to the limiting slot and a positioning protrusion for inserting the positioning slot.

The present disclosure discloses an illumination device, which includes: a housing, a plurality of light source modules positioned in the housing, and a plurality of connection lines electrically connecting the plurality of light source modules. Each of the light source modules includes a base, a light source substrate provided on the base, a plurality of light sources provided on the light source substrate, electrical connection elements provided on the light source substrate, and a light distribution element connected with the base and/or the light source substrate. The light source substrate and the electrical connection elements are disposed between the light distribution element and the base, and the connection lines and the electrical connection elements are electrically connected.

Methods and apparatus are presented for retaining a dome lens in a lighting element that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting element includes a dome lens that is removably positioned proximal to a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

An airfield light, components thereof, and associated methods. The airfield light can include a baffle including a baffle body and one or more baffle members secured to the baffle body. The baffle members are configured to cover portions of a baffle window. At least one light source is mounted in association with the baffle and emits light out of the baffle window. The baffle members cover portions of the baffle window for blocking light transmission therethrough. A method of assembling an airfield light includes arranging a baffle to shroud a light assembly and removing a baffle member to permit light from the light assembly to emit through a portion of a baffle window opened by removing the baffle member. A baffle for an airfield light is also disclosed.

A light emitting device module including a substrate including a plurality of light emitting areas, light emitting devices disposed in each light emitting area and to emit light, windows disposed on the substrate, each of the windows covering one of the light emitting areas and having an asymmetrical shape with respect to one direction, and a holder for coupling the windows, the holder including a plurality of openings each having an asymmetrical shape, in which each of the windows is individually disposed in a corresponding one of the openings and is detachably coupled to the holder.

The present invention provides a lens (i.e., luminous flux control member) for an optical element of a backlight, capable of easily aligning the orientation in the plane direction. The luminous flux control member according to the present invention includes a lens main body and legs. The lens main body includes a light-entering area for light emitted from a light-emitting element to enter on the lower surface side and a light-emitting area for emitting the light entered from the light-entering area to the outside on the upper surface side. The legs are legs for mounting the luminous flux control member on a substrate on which the light-emitting element is mounted and are disposed on the lower surface of the lens main body so as to project downward. The luminous flux control member satisfies the following condition 1 or 2: (Condition 1) at least one of the legs is accommodated in one of two grooves having different widths, and all of the other legs are accommodated in the other groove only when the lens main body is oriented in one predetermined direction or an opposite direction thereto; and (Condition 2) the lens main body or all of the legs are accommodated in one groove only when the lens main body is oriented in one predetermined direction or an opposite direction thereto.

A light module includes at least one light source, a light source support, and an optical element suitable for receiving rays emitted by the light source. The optical element includes structure for positioning the optical element in a predefined position on the support and an elastic attachment device for attaching the optical element in the predefined position on the support.
