A light fixture can include a housing having at least one housing wall having an inner surface that forms a cavity, where the inner surface of the at least one housing wall has at least one baffle coupling feature disposed thereon. The light fixture can also include a baffle removably coupled to the housing, where the baffle includes at least one baffle wall having an outer surface, where the outer surface of the at least one baffle wall has at least one housing coupling feature disposed thereon. The baffle can be coupled to the housing and decoupled from the housing without use of tools.

A large-angle LED working lamp comprising a shell, a lampshade clamped with the shell, light-emitting units arranged in the shell and a connector electrically connected with a power generation unit; the light-emitting unit comprises a circuit board and a convex lens; a light-emitting diode is arranged on the circuit board, and the convex lens covers the light-emitting diode; the number of the light-emitting units is three, comprising a central light-emitting unit and two side light-emitting units that are symmetrically arranged on the two sides of the central light-emitting unit; the angle formed between each side light-emitting unit and the central light-emitting unit is 20-30 degrees; through the central light-emitting unit and the two side light-emitting units that are symmetrically arranged on the two sides of the central light-emitting unit, the light-emitting angles in three different directions can be formed so that the illuminating angle can reach 90-120 degrees.

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.

A light fixture includes a lamp having a light source, a petal mechanism having a plurality of petals moveable between an open position and a closed position, and a petal actuator coupled to the petal mechanism to controllably move the petals of the petal mechanism between the open position and the closed position.

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.
