The invention relates to a light device for a motor vehicle, comprising a matrix light source having a matrix of elementary light sources with an electroluminescent semiconductor element. Each elementary light source has an emitting surface that is less than or equal to 0.2 mm2. The measures proposed by the invention allow such a matrix light source to be powered without any risk of damage due to overheating of the semiconductive junctions of the elementary light sources that make up the light source.

A LED light driver having a reduced overall thickness so as to facilitate placement within an octagon junction box and canopy. The LED light driver of the present invention includes a printed circuit board wherein the printed circuit board includes a first side and a second side and is planar in manner. The printed circuit board further includes a plurality of recesses formed on the first side and second side thereof so as to facilitate the reduction in the overall Z dimension of the LED light driver. The printed circuit board includes a metal base having an epoxy material utilized for insulation and an exterior case material. The metal base enclosed inside the epoxy further functions as a heat sink. The reduced height of the present invention further provides for less blockage of light and as such the LED light drive can be more proximate the light source.

A light-emitting module includes a first terminal, a second terminal, a first light source, a second light source, and a third light source. The first light source is connected between the first terminal and the second terminal. The second light source and the third light source are connected between the first terminal and the second terminal, in anti-parallel with the first light source. The first, second, and third light sources are aligned in a first direction along a light-emitting surface, with the first light source between the second light source and the third light source.

An LED light source module includes a circuit board, solid-state light emitting elements arranged on the circuit board, a heatsink disposed in contact with the circuit board and having a channel formed inside, through which refrigerant flows, and a switching unit configured to switch a flow direction of refrigerant through the channel to an opposite direction.

A method of controlling an LED system with a control signal having a first control scheme may include providing a lighting module including a control module, an LED driver connected to the control module, and at least one LED connected to the LED driver; receiving, at the control module, the control signal having a first control scheme; comparing the first control scheme to a predetermined second control scheme; when the comparing determines that the first control scheme is the same as the predetermined second control scheme, transmitting to the LED driver a driver control signal including the predetermined second control scheme; and when the comparing determines that the first control scheme is different from the predetermined second control scheme, translating, with the control module, the first control scheme into the predetermined second control scheme and then transmitting to the LED driver a driver control signal including the predetermined second control scheme.

An LED light source with a lens is mounted to a light housing. The lens is sealed to form an encapsulated atmosphere about the LED. The housing has a cylinder and a divider between the cylinder and the LED. A slidable and sealed piston in the cylinder creates an air chamber between its upper surface and the divider and a lower surface of the piston is exposed to air pressure of the outer atmosphere. A conduit is formed through the divider to interconnect the encapsulated atmosphere with the air chamber in the cylinder. LED heat causes the pressure of the encapsulated atmosphere to increase, and it flows through the conduit to press against the piston. This piston slides to create a larger air chamber to equal the increased pressure of the encapsulated atmosphere to the pressure of the outside atmosphere. The reverse occurs when the LED cools.

A lighting device includes a body, a lighting module, and a cap. The body includes a cavity, the cavity including an aperture. The lighting module is in the cavity and include a push button switch. The cap covers the aperture and include an outward side and an aperture side having a protrusion. The protrusion and push buttons switch are positioned such that they are proximate and when the cap is pushed inward near the protrusion, the protrusion pushes the push button switch and activates the lighting module. The cap includes a ridge surrounding the protrusion on the outward side, the ridge preventing the protrusion from being pushed into the push button switch, unless the cap is pressed at approximately a location of the protrusion.
