A gas lighting device having a casing fastenable to an electric household appliance by means of fastening means coupleable with corresponding perforations obtained on a carrying element of the electric household appliance; wherein the fastening means consist of at least one pair of elastically deformable fastening elements protrudingly carried by the casing, perpendicularly to the same, in a position immediately adjacent one to the other so that they are adapted to snappingly couple with only one and the same of said perforations of the carrying element of the electric household appliance.

Device for transfer of equipment for a wireline operation in a well connected to a drilling derrick via a top drive. The device comprises a beam structured for releasable connection to said top drive; wherein the beam is structured in a manner allowing it to extend, when in its position of use, transversely relative to a center line between the top drive and the well; wherein the beam is provided with at least one hoisting device with a lifting line for vertical movement of said equipment; wherein a support point for the lifting line is connected to the beam and is structured so as to be movable in the longitudinal direction of the beam, whereby said equipment may be moved horizontally relative to said center line; and wherein said hoisting device and support point are structured for remote-controlled operation.

An embodiment provides a method and a device for outputting a light, which can output a light in a safe manner. Specifically, disclosed are a method and a device for outputting a light, which control an output light to prevent the output light from being concentrated on a specific area.

A photosensitive lithographic printing plate comprising a hydrophilic support and a photopolymerizable photosensitive layer containing: (i) a sensitizing dye having an absorption maximum in a wavelength range of from 360 to 450 nm; (ii) a hexaarylbisimidazole compound; (iii) an addition polymerizable compound having an ethylenically unsaturated double bond; (iv) a binder polymer; and (v) a mercapto compound represented by the following formula (1) as defined herein.

A sealing process of LED modules, comprising: (1) a waterproof wire goes through a wire-through hole of a heat sink to be connected with a positive-negative solder joints on a PCB board, wherein the positive-negative solder joint and the position that the waterproof wire going through are subjected to glue sealing treatment, and a waterproof sealing process is operated between the waterproof wire and the wire-through hole; (2) fix the PCB board on the heat sink; (3) place one sealing ring into one of the grooves; (4) apply evenly a ring of liquid silica gel along the other groove of the lens set and the amount of the liquid silica gel is limited to completely sticking the solid silica gel sealing ring; (5) the heat sink installed with the PCB board and the waterproof wire as processed in step (2) is inversely buckled on the lens set which is set with the solid silica gel ring and the liquid silica gel as processed in step (4), so as to fix the heat sink entirety and the lens set. At least two waterproof sealing rings are used for completely isolating an LED chip from the outside so as to prevent all water vapor or other harmful gases from corroding the chip and the PCB, and the sealing rings are firmer when being compared with thin film sealing; the service life is longer and the guarantees to the sealing performance between the lens set and the heat radiation frame are realized.

A lighting apparatus having laser light as a light source is provided. The lighting apparatus includes: a light-emitter which radiates light of a wavelength different from a wavelength of the laser light; and a lens including a light distribution controlling structure that controls distribution of the light radiated from the light-emitter. The lens is disposed opposite a laser light entry side of the lighting apparatus. The light-emitter is disposed between the lens and the laser light entry side. The lens integrally includes, along an optical axis of the laser light, a light-dispersing structure configured to disperse the laser light.

Exemplary embodiments of the present disclosure are directed towards an integrated smart helmet system, comprising: a control unit-PCB 201 is wirelessly connected to a computing device 303 over network 305, computing device 303 is configured to enable a user to use different functionalities without having to remove helmet 102 and access the computing device 303 and the control unit-PCB 201 is configured to detect crashes while wearing the helmet 102 by the user and notify crash detected information to computing device 303 over network 305, buttons 213a-213d are positioned at the rear or side of helmet 102 and control unit-PCB 201 is electrically coupled to buttons 213a-213d, buttons 213a-213d are configured to initiate prompts to direct the user to put away the computing device 303 while driving and disable certain dangerous functions.

A lighting system and a method for a operating a lighting system, enabling to obtain an identification tag (7) comprised in lighting design data (5) directly from an output beam (3), i.e. from the emitted light of the at least one lighting unit (2). It is thus possible to trace any unauthorized distribution of a lighting design by monitoring the emitted light without the need to directly access the controller or any other part of the lighting system.
