The second end part is fixedly connected to the bottom fixing part. The simple net cover device is characterized by simple processing and assembly, low manufacture cost, not easy to wear in bottom and long life, and can ensure the net cover is supported. The present invention also provides a lamp including the simple net cover device, which can not only be used alone, but also can be strung into a string of lamps to meet the diversified use needs of the users.

In some embodiments, a lighting apparatus includes a back cover, a first light source, a second light source, a back cover, a first separator and a driver. The first light source is mounted on the back cover. For example, the first light source includes multiple LED modules mounted on a circular ring structure. The circular ring structure is fixed to the back cover. Each LED module may have a LED chip covered by a lens module for guiding an output light of the LED chip to desired directions, e.g. to form a condensed light beam or to diffuse evenly on a projected surface.

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.

A cove lighting system includes a plurality of cove extrusions and a plurality of mounting brackets. Each cove extrusion is a single extrusion defining a cove channel and mounting features. The mounting brackets are attached to the wall and the cove extrusions are hung from the mounting brackets with the mounting features. The cove extrusions are hung immediately adjacent to each other to define a continuous cove channel to receive one or more power boxes, and one or more luminaires.

A device and the method of installing and adjusting same, which provides reduction of glare from overhead lighting, including but not limited to “can” lighting, also referred to as recessed lighting.

A low profile lighting device for installation on a flat surface such as a ceiling. The low profile down light can have a housing comprising a generally planar surface and a sidewall rising from the planar surface; a PCB with a plurality of LEDs affixed to the generally planar surface of the housing; a lens in contact with the sidewall of the housing and having a first side facing the LEDs on the PCB such that light from the LED illuminates the first side of the lens; and a trim ring adapted to slide over the housing and having a first end and a second end opposite the first end, wherein the first end has a plurality of tabs adapted to secure the trim ring to a housing and the second end has an inwardly projecting lip adapted to contact the second side of the lens thereby securing the lens to the housing.

A lighting system includes a substrate element, one or more light sources mounted on a surface of the substrate element, and an optical device for modifying light distribution. The lighting system further includes one or more fastening elements each being attached on the surface of the substrate element and including at least one spring arm for elastically engaging the optical device to hold the optical device in place. The optical device includes one or more apertures and each fastening element is arranged to protrude through a corresponding aperture of the optical device, and the at least one spring arm of the fastening element is arranged to elastically engage edges of the corresponding aperture of the optical device.

A method and apparatus for forming a sealant coating on a fastener are provided. The apparatus comprises a light generator, a light housing, and a forming cup. The light generator is configured to generate light having a number of characteristics that cures the sealant coating on the fastener. The light housing surrounds the light generator. The forming cup is removably connected to the light housing. The forming cup has an internal cavity with an inner mold line complementary to an outer mold line for the sealant coating.

The present invention discloses a panel light mounting structure, a panel light and mounting method thereof. The panel light mounting structure comprises a fixing slot disposed on the back of the light body and a mounting bracket to snap-connect with the matching fixing slot. The present invention adopts a sliding and snap-in method to match and connect the panel light body with the mounting bracket. The installation is easy and fast, and the ceiling-mount effect is excellent. In addition, the present invention may also achieve the blinds operation during the panel light installation process.

A minimally complex, low cost/economical luminaire that distributes point source light for general lighting applications, the luminaire having a substrate with a linear array of discrete light sources positioned to emit light into an air-filled cavity and a light redirecting assembly on the other side the air-filled cavity, the assembly comprising a clear, light transmissive rigid cover and a clear, light transmissive semi-rigid flexible film positioned between the cover and the substrate, wherein the film is non-adhesively secured within the luminaire and flexed to generally conform to the shape of the cover and wherein the surface of the film facing into the air-filled cavity comprises an array of optical relief structures extending into the air-filled cavity.
