A lighting and/or signaling device, in particular for the automotive industry, comprising a container body which delimits a containment housing closed by a lenticular body, which accommodates at least one light source adapted to emit a light beam which at least partially crosses the lenticular body, at least one decorative element, applied on an external wall of the lenticular body, opposite to the containment housing. An internal wall of the decorative element, directly facing the external wall of the lenticular body, comprises at least one welding pin, which creates a welding point with the lenticular body. At least one spacer element defines a minimum clearance and a volume or gap between the external wall of the lenticular body and the internal wall of the element decorative element. At least one conveyor element favors the outflow of liquids which have penetrated through the clearance into the volume.

The present invention is related to an illumination system that enables installation conditions to be simplified, such that the gap area of the wall, ceiling or floor wherein said illumination system is integrated is minimised, in addition to facilitating the insertion of the electrical contacts of the functional unit and enabling the concealment thereof to be carded out without modifying the conductive properties thereof, minimising all the functional elements arranged inside the gap of the wall ceiling or floor.

Disclosed is a recessed lamp which includes a surface ring, a diffusing plate and a light emitting assembly, wherein the surface ring is provided with a light exiting opening and has an inner side surface and an outer side surface, and a protruding ring surrounding the light exiting opening is arranged on the inner side surface; the diffusing plate abuts against the inner side of the surface ring to cover the light exiting opening and is fusion sealed to the surface ring; and the light emitting assembly includes a substrate and LED lamp beads arranged on the substrate to emit light towards the light exiting opening.

A lighting system for fixtures comprising a removable façade configured to connect or being prior mounted or fabricated with a fixture, the removable façade including an outermost apron, a translucent panel including at least one opening, a sheet panel having at least one reinforcement element, and at least one light source disposed therein, wherein the apron includes at least one opening disposed thereon, and wherein the at least one light source is configured to emit light thought the at least one.

An optical module includes a beam-tilting light source enclosure. The enclosure is coupled to a substrate that includes a light emitter connected thereto. The enclosure has a geometry such that the enclosure has a first surface configured to couple substantially flat to the substrate and a second surface tilted with respect to the first surface and configured to couple substantially flat to a component of an electronic device through which the light is to project. The enclosure is optically transmissive and covers the light source when coupled to the substrate. In this way, the enclosure may be assembled and used in the electronic device by coupling the first surface to the substrate and coupling the second surface to the component.

The present disclosure relates to a method of manufacturing a tamper proof light emitting module comprising the steps of (a) pre-assembling the light emitting module into a testing configuration including a housing and one or more light emitting elements mounted within the housing, the housing including first and second housing components connected together using at least one removable fastener connecting the first and second housing components; (b) testing the light emitting module to confirm the light emitting elements are operable; (c) after step (b), removing the removable fastener; (d) replacing the removable fastener removed in step (c) with at least one breakaway fastener; and (e) tightening the breakaway fastener(s) until the head of the breakaway fastener(s) breaks off so that the breakaway fastener(s) is no longer removable, thereby creating a final, tamper proof configuration of the light emitting module.

A light sensing module and an electronic device using the same are provided. The light sensing module includes a substrate, a light sensing unit, a first light-transmissive component and a blocking wall. The light sensing unit is disposed on the substrate to sense an intensity of a working light beam. The first light-transmissive component covers the light sensing unit, and has a first refractive index that is between a refractive index of the light sensing unit and a refractive index of air. The blocking wall is disposed on the substrate, and surrounds the light sensing unit and the first light-transmissive component.

An optical member includes a curved portion comprising an optically transmissive material. The enclosure has an outer surface and an inner surface opposite the outer surface. At least one light redirection feature protrudes from the inner surface. At least one indentation defined on the outer surface is configured to refract light.

A light emitting diode (LED) tube lamp configured to receive an external driving signal includes an LED module for emitting light, the LED module comprising an LED unit comprising an LED; a rectifying circuit for rectifying the external driving signal to produce a rectified signal, the rectifying circuit having a first output terminal and a second output terminal for outputting the rectified signal; a filtering circuit connected to the LED module, and configured to provide a filtered signal for the LED unit; and a protection circuit for providing protection for the LED tube lamp. The protection circuit includes a voltage divider comprising two elements connected in series between the first and second output terminals of the rectifying circuit, for producing a signal at a connection node between the two elements; and a control circuit coupled to the connection node between the two elements, for receiving, and detecting a state of, the signal at the connection node. The control circuit includes or is coupled to a switching circuit coupled to the rectifying circuit, and the switching circuit is configured to be triggered on or off by the detected state, upon the external driving signal being input to the LED tube lamp, to allow discontinuous current to flow through the LED unit.

A backlight module and a display device are provided. The backlight module includes a back plate, a carrying member, a light guide plate, at least one optical film and a light source. The carrying member is disposed on the back plate, in which the carrying member includes a first step portion and a second step portion, and the first step portion is elevated higher than the second step portion. The light guide plate is disposed on the back plate. The at least one optical film is disposed above the light guide plate, in which the at least one optical film is held on the second step portion. The light source is disposed on the back plate, in which the light source is disposed adjacent to a light-incident surface of the light guide plate.
