Light with housing, a plurality of illuminants arranged in the housing, a covering disc that closes the housing in the direction of radiation and a film for altering the radiation characteristics of the illuminants, which is arranged in front of the illuminants in the direction of radiation, wherein the film is arranged between the covering disc and a supporting disc, wherein the film is in direct contact with the two discs.

A theftproof lamp (100), including a lamp body (110) and a lamp cap (120). A spring member (140) and a ratchet wheel mechanism (130) are provided inside the lamp for cooperating with each other and enabling theftproof effect. When turning the lamp clockwise, the lamp can be screwed down to a lamp socket. When turning the lamp counter-clockwise, the lamp can only make repetitive circular motions around the ratchet wheel and therefore achieve the theftproof effect. When a user needs to remove the lamp in a safe way, a bolt (170) can be moved inwardly to block the spring member from moving upward, so that the lamp body, ratchet wheel and lamp cap form a whole, without any movement in relation to each other, and therefore allowing easy removal of the lamp.

A lamp system (10) includes a straight tube type lamp (13) and a socket (14). The straight tube type lamp (13) includes a straight tube type cover (20) containing a light-emitting element, and caps (23) arranged at both ends of the cover (20). A pair of lamp pins (30) whose tips respectively protrude in directions intersecting a lamp longitudinal direction are protrudingly provided on end faces of the caps (23) at both the ends. The socket (14) includes a socket body (41), a rotor (42) which is arranged in the socket body (41) and on which the pair of lamp pins (30) of the straight tube type lamp (13) are mounted, and a pair of terminals to which the pair of lamp pins (30) mounted on the rotor (42) are connected. At least the rotor (42) can move in the lamp longitudinal direction.

An LED filament, comprising: an enclosure; a linear array of LED devices; and an electrical connector, wherein: the enclosure includes an optically transmissive binder; and the linear of LED devices is conformally wrapped around by the enclosure to be operable to emit light when energized through the electrical connector.

A light guiding structure includes a resilient base and a plurality of light guiding columns. A plurality of through holes is separately formed on the resilient base. The plurality of light guiding columns resiliently engages with the plurality of through holes. Each of a plurality of light emitting components is disposed on an end of each of the plurality of the light guiding columns. The light guiding structure utilizes the plurality of light guiding columns for guiding the light transmitted from the plurality of light emitting components and further utilizes the resilient base for allowing the light transmitted from one of the plurality of light emitting components to pass through the corresponding light guiding column only. Therefore, the light transmitted from the plurality of light emitting components can be guided to a correct position, which effectively reduces human misjudgment.

A ceiling light apparatus includes a base plate, a light passing cover, a driver and a light source module. The base plate has a center protrusion portion and a peripheral protrusion portion. In addition, the base plate has a peripheral wall. The driver is disposed in the center protrusion portion. The light source module is disposed on the front side of the base plate. The driver is disposed on the front side of the base plate.
