A lighting device including at least one first light source emitting a visible light, at least one second light source spaced apart from the first light source and emitting a light having a wavelength for sterilization, and a housing, in which the first light source and the second light source are disposed, in which the first light source is disposed outside an area having an angle corresponding to about 50% of a maximum amount of light emitted from the second light source based on a line extending from a center of the second light source along a direction substantially perpendicular to a light emitting surface of the second light source.

Shades and/or reflectors for luminaires. The luminaires may be retrofitted with the shades and/or reflectors to selectively control the direction and/or spectrum of light emitted by the luminaires. In particular, the efficiency and/or color contrast of a luminaire may be improved by using wavelength shifting material, such as a phosphor, to absorb less desired wavelengths and transmit more desired wavelengths. The shade may provide a transmissive filter which reflects desired wavelengths such as red and green, while passing less desired wavelengths (e.g., blue) toward the wavelength shifting material which emits such as light of more desirable wavelengths.

An insert device for receiving an artistic medium thereon for use with a lampshade. The device may include an insert configured to be used in association with a lampshade. The insert may include a first side and a second side. A design may be located on the first side of the insert, where the insert with the design is configured to be drawn on using an artistic implement. The insert may be made from a translucent material that is capable of receiving and retaining an artistic medium thereon. The artistic medium can be erased or otherwise removed from the translucent material. The design on the insert may be used in association with a lampshade such that it is exposed for viewing in association with the lampshade when the insert is in a three-dimensional shape.

The present invention discloses a novel three-dimensional modeling lamp and a manufacturing method thereof. The lamp comprises a lamp shell and a light source arranged in the lamp shell, wherein the lamp shell forms a preset three-dimensional modeling by connecting a plurality of sheets with different shapes through connectors, and the sheets comprise a light-transmitting PET layer and a colorful film layer, the colorful film layer refracts light emitted by the light source, so that the lighting effect of the three-dimensional modeling lamp is better; and a plurality of indentations are formed on the sheets, and the indentations guide users to splice and shape the sheets more conveniently. The manufacturing method comprises the following steps: selecting corresponding sheets according to the preset size and external shape of the three-dimensional modeling lamp, and carrying out indentation treatment on the sheets to facilitate the installation of users.

The lamp shade is formed by a hollow enveloping body with laminar structure closed on itself. In an operative position it is assembled on a support structure and extends laterally around a light source, configuring an upper opening and a lower opening. The enveloping body comprises an exterior face and an interior face relatively rigid in the vertical direction and relatively flexible in the horizontal direction, the vertical direction being that which goes from the upper opening to the lower opening. The interior face comprises at least one corrugated surface portion vertically and at least one perimeter channel (6) perpendicular to the corrugations of the at least one portion for coupling the shade to the support structure.
