A lamp having a first illumination module, a second illumination module and a control circuit is provided. The first illumination module has a first light-emitting surface, and the second illumination module has a second light-emitting surface connected to the first light-emitting surface. The control circuit is coupled to the first illumination module and the second illumination module. When the control circuit increases the luminance of the first illumination module and the luminance of the second illumination module, a percentage of increasing the luminance of the first illumination module is less than a percentage of increasing the luminance the second illumination module.

A lighting device for use with one or more other networked devices is disclosed. In embodiments, the lighting device may comprise an outer globe, a diffuser, an outer cowling, a power input connector, a power control printed circuit board, a communication and control printed circuit board, an indicator printed circuit board, one or more microprocessors, a real-time clock, a supercapacitor, and an LED lighting printed circuit board. In embodiments, the real-time clock may be powered by the supercapacitor to track time without power from an input power source for the lighting device, enabling the lighting device to implement time-dependent settings, such as pre-programmed color temperatures and/or light intensities. The lighting device may communicate with one or more other networked devices, such as second lighting devices, mobile phones, servers, remote controls, and/or home or office automation equipment. The lighting device may be powered through a light socket.

An article of illuminated headwear having a top portion, a left side, and a right side, the article of headwear including a controllable power source, a lamp disposed on the top portion of the article of headwear, the lamp in electrical communication with the power source, a first lens configured to cast white light in a 360 degree pattern around the lamp, a second lens disposed on the right side of the headwear, the second lens configured to cast light of a first color to the right side of the headwear, and a third lens disposed on the left side of the headwear, the third lens configured to cast light of a second color to the left side of the headwear.

The invention provides a lighting unit (1) comprising (a) a light source (10) configured to provide a beam of light (11), the light source (10) having a light exit surface (12) for escape of the light from the light source (10), (b) a lamp shade (20) partly surrounding the light source (10), wherein the lamp shade (20) has an internal lamp shade surface (21) and a lamp shade light exit (22), and (c) a light conversion element (30), configured partly between the light exit surface (12) of the light source (10) and the lamp shade light exit (22) of the lamp shade (20), wherein the light conversion element (30) comprises a light transmissive part (31), wherein the light transmissive part (31) comprises a luminescent material configured (40) to convert at least part of the beam of light into luminescent material light.

A lamp shade is provided for covering a light source. The lamp shade has a hoodlike base body which is open at least at the bottom and at least partly transparent, which is placed over the light source and covers it. The base body can have on its outer surface at least one encircling indentation, in which a decorative ring is adapted to be fitted and braced there.

A rotatable illuminator has a housing and an illuminating body. The housing has an inner space and an opening. The illuminating body is rotatably mounted in the housing, and has an illuminating element. When the illuminating body is rotated until the illuminating element is toward the opening of the housing, the rotatable illuminator can be hanged to be used as a hanging lantern, or the user can directly hold the housing to use the rotatable illuminator as a flashlight. When the illuminating body is rotated until the illuminating element is toward the inner space of the housing, the rotatable illuminator can be put on a table to be used as a table lamp. As a result, the rotatable illuminator can be used as the hanging lantern, the flashlight, and the table lamp, and thus can reduce the cost and facilitates ease in portability.

A light emitting diode (LED) bulb includes a connecting body, a lamp cap located at a first end of the connecting body, a mounting base located at a second end of the connecting body opposite to the first end, a plurality of LED modules mounted on the mounting base and a sheath assembled to the second end of the connecting body. The sheath includes a first portion and a second portion detachably engaged with the first portion to cooperatively define an enclosed space enclosing the mounting base and the LED modules therein.

A deck light assembly for attachment to a deck railing includes a C-shaped body with a core nesting within a cover and a top plate extending between two legs. The body includes a top plate extending between a first leg and a second leg. An LED light and a battery may each be disposed within the body between the core and the cover. Each of the legs of the core may define a clamping member, with the clamping members in mirror-image pairs across from one-another for securing the deck light assembly upon the deck railing, and each clamping member having a V-shaped cross-section with a top portion extending downwardly and inwardly away from the associated leg to a knuckle, and with a bottom portion extending downwardly from the knuckle and outwardly toward the associated leg. The clamping members may be flexible outwardly for allowing the deck light assembly to be easily removed or repositioned on the deck railing.
