The invention relates to a method for forming a luminaire (1), which has a trough-shaped luminaire housing (10, 110) having a region (25, 125) for accommodating illuminants, which is surrounded by a seal (40), a cover (70, 80) which spans the region (25, 125) and abuts the seal (40) in a peripherally closed manner, a frame-like holding element (50, 150), which presses the cover (70, 80) into abutment with the seal (40). For the luminaire housing (10 110), the cover (70, 80) and the holding element (50, 150), are each available in at least two different variants, which can be combined in any way, wherein in order to form the luminaire (1) according to desired output properties and/or properties with regard to heat dissipation or moisture resistance, a suitable luminaire housing (10, 110), a cover (70, 80) and a holding element (50, 150) are in each case selected and the selected components are assembled to form the luminaire (1).

A light bundle control member comprises: an incident plane which is an inner surface of a recess opening toward a back side so as to intersect a central axis of the light bundle control member; an exit plane disposed on a front side so as to intersect the central axis; a back surface which is connected to an opening edge of the recess and formed so as to be spaced apart from the opening edge of the recess; and a protrusion disposed on the back surface and protruding from the back surface toward the back side. A tip-end surface of the protrusion and at least an area surrounding the protrusion on the back surface have different properties.

A dazzle lamp structure of a microphone speaker comprises a shell, a mounting base, a microphone, a microphone cover, and an LED lamp panel, wherein multiple LED chips are disposed on the LED lamp panel, a white semi-transparent inner lampshade is disposed at the top of the shell and covers the LED lamp panel, the top of the inner lampshade is covered with a dark transparent outer lampshade, and lights emitted by the LED chips sequentially penetrate through the inner lampshade and the outer lampshade to shine out. The dazzle lamp structure can shield strong lights and has a better lighting rendering effect.

A lamp bracket and bracket-type UV fluorescent lamp. The lamp bracket includes: a backboard component, the first lamp base component, the second lamp base component and an inductive component; the first lamp base component is provided on one end of the backboard component; the second lamp base component is provided on the other end of the backboard component, connects to the first lamp base component electrically and is provided with a mounting groove, and works with the first lamp base component and backboard component to form a containing groove in an enclosure way which is used for installing UV fluorescent tube; inductive component is provided in the mounting groove, connects to the second lamp base component and/or the first lamp base component electrically, is used for sensing humans, works with the second lamp base component and/or the first lamp base component to turn on or turn off the fluorescent tube.

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 lighting unit includes a light source configured to radiate a light, a circuit board on which the light source is mounted, and multiple stages of condenser lenses configured to condense the radiation light radiated from the light source. A first-stage lens that is located closest to the light source and given a maximum positive power among the multiple stages of condenser lenses has a partition wall portion and a positioning portion. The partition wall portion partitions an accommodation space in which the light source is accommodated in a range from a composite focal point of the multiple stages of condenser lenses to the first-stage lens by projection toward the circuit board side. The positioning portion 222 is provided on the partition wall portion and positioned relative to the circuit board by concavo-convex fitting.

A segmentally extendable modular handheld flashlight and a respective kit-of-parts for assembling the same are described, in which at least one battery segment configurable as an electric charger, in a dismantled conformation.

The lighting apparatus includes a top cover, a light passing cover, a lens, a light source plate, and a bottom cover. The top cover has a light opening. The light passing cover is fitting the light opening. A diffusion illumination or a light beam is selected by placing the light passing cover or the lens to the top cover respectively. The light source plate is mounted with a LED module. A base plate is used for mounting the light source plate and for connecting to the top cover forming a container space. The base plate has at least one receiver socket for connecting to an external device to electrically connect the LED module.
