An illumination module and a lamp, the illumination module is adapted to be assembled with at least two different installation components. The illumination module includes: a housing including a main body part, a side wall extending from the main body part, and an installation region for disposing the installation components, the installation region includes a first installation part and a second installation part, the first installation part is located on an outer periphery of a back face of the main body part of the housing and configured to be assembled with an installation component, and the second installation part is located on the side wall at the back face of the housing and configured to assemble with an installation component; and a light source component, installed on a front face of the main body part of the housing.

A method of illuminating a target area and driving rotation a driven tool comprises coupling a light attachment assembly to an elongated extension member by placing a portion of the elongated extension member within a hollow portion of a sheath of the light attachment assembly. Activating a light source of the light attachment assembly. Positioning the driven tool within the target area while grasping the light attachment assembly. Driving rotation of both the driven tool and the elongated extension member while grasping the light attachment assembly when the driven tool is positioned within the target are such that the portion of the elongated extension member housed within the hollow portion of the sheath rotates relative to the light assembly.

Optical lenses for illumination purposes (L) are proposed, comprising a lateral surface (C) and a light exit surface (B), wherein the underside is shapes in a plane fashion and has an optical relevant cutout for receiving a light source, which is distinguished by the fact that the lens (L) has a lateral surface (C) that is wholly reflectively coated, and has a light exit surface (B) having the two vertices (b1) and (b2), wherein (b1) and (b2) represent respectively the highest and lowest vertices upon the transition from the light exit surface (B) to the lateral surface (C).

The invention relates to a lighting device, which includes a light source, a pattern disc provided with a plurality of pattern sheets, a rotating shaft and a drive mechanism. The rotating shaft passes through the axial center of the pattern disc and is driven to rotate by the drive mechanism to rotate the pattern disc. The pattern sheets are then rotated in turn to a light path of the light emitted by the light source. The lighting device further includes a positioning unit for pattern disc including a Hall plate, a fixing bracket for the Hall plate and a magnet. The Hall plate is mounted on the fixing bracket for the Hall plate, and the magnet is mounted on the pattern disc. The pattern disc is rotated to bring the magnet close to the Hall plate to generate magnetic induction. According to the present lighting device using the Hall induction principle and the Hall plate, the reset and positioning of the pattern disc of the lighting device is effectively realized with less errors, and the precision of the reset positioning of the pattern disc and the artistic ambience effect of the light fixture are improved. Therefore, the lighting device is applicable to the reset and positioning of pattern discs of various kinds of light fixtures.

A waterproof lamp includes a housing having an inner cavity for receiving a lamp body, and at least one end forming a wiring opening for drawing out wiring; a wiring end cover is sealed on the wiring opening and can be threaded out; a first sealing member is formed between the wiring end cover and the interior surface of the housing and engages with the wiring end cover for the wire to pass through; the wiring end cover includes a fixed cover and a movable cover, the movable cover is detachably coupled to the outer side of the fixed cover; and a second sealing member is disposed between the movable cover and the fixed cover. The first sealing member of the waterproof lamp is filled with liquid and can be solidified to form a waterproof rubber layer sealed between the first sealing member and the inner wall of the housing.

A light emitting arrangement (100, 200, 300) is provided, comprising: a body (10) of solid material having a surface (11); a light guiding member (101, 110) partially embedded into said body, having a plurality of discrete light outcoupling regions (103) comprising light outcoupling means (230, 730, 830, 930) distributed along a longitudinal direction of the light guiding member, and a plurality of discrete, non-outcoupling regions (102) distributed along a longitudinal direction of the light guiding member, wherein said plurality of light non-outcoupling regions of the light guiding member are embedded by said body and said plurality of light outcoupling regions of the light guiding member are exposed on the surface of said body, wherein said non-outcoupling regions (102) form light incoupling regions comprising light incoupling means (220, 320, 420, 520, 620); and a plurality of solid state light sources (12) embedded within said body (10) of solid material arranged to emit light towards said light incoupling regions.
