A light-emitting diode (LED) light bulb includes an outer housing assembly, an inner housing assembly, an LED circuit board and a lamp cap. The outer housing assembly has a non-metallic outer shell and an inner shell affixed to an inner wall of the outer shell. The inner housing assembly is mounted inside the outer housing assembly through a lower opening of the outer housing assembly and is non-metallic and elongated with one end thereof securely connected with the base. The LED circuit board is mounted on a top of the LED mounting disc. The lamp cap is non-metallic and covers the upper opening of the outer housing assembly. Because the outer housing assembly and the lamp cap enclose the LED circuit board therein, users do not easily get an electric shock when holding the outer housing assembly or the lamp cap upon mounting or dismounting the LED light bulb to or from an LED lamp holder.

A light emitting diode (LED) module is in thermal communication with front and back heat sinks for dissipation of heat therefrom. The LED module is physically held in place with at least the back heat sink. A mounting ring and locking ring can also be used to hold the LED module in place and in thermal communication with the back heat sink. Key pins and key holes are used to prevent using a high power LED module with a back heat sink having insufficient heat dissipation capabilities required for the high power LED module. The key pins and key holes allow lower heat generating (power) LED modules to be used with higher heat dissipating heat sinks, but higher heat generating (power) LED modules cannot be used with lower heat dissipating heat sinks.

A light emitting diode module is removably coupled to a heat sink with screws and includes slots configured to receive at least a portion of the screw therethrough, the width of the slot being greater than the thread-width of the screw but less than the width of the screw head. Some slots also include a keyhole having a diameter greater than the width of the screw head. For embodiments without keyholes, the module is coupled to a heat sink by loosening the screws, sliding them into the slots, and tightening the screws to hold the LED module in place. For embodiments with one or more keyholes, the keyhole is vertically aligned with the screw, the module is moved down over the screw, and the screw is moved into the narrower portion of the slot. Then, the screws are tightened to hold the module in place against the heat sink.

A method is provided for removing a light-emitting diode (LED) module from a luminaire that has a controller and a housing. The housing encloses an optical system that includes the LED module and other optical devices. The method includes electrically uncoupling an LED circuit board of the LED module from the controller. The method further includes mechanically uncoupling the LED module from the luminaire without removing other optical devices of the optical system from the housing.

Example embodiments relate to luminaire systems with improved fastening means. One example luminaire system includes a first support provided with a recess. The luminaire system also includes a plurality of light sources arranged on said first support. In addition, the luminaire system includes a second support arranged opposite said first support. Further, the luminaire system includes one or more optical elements provided to said second support, and associated with the plurality of light sources. Additionally, the luminaire system includes a fastening element that includes a head portion and a rod portion. The second support is provided with a through-hole for receiving said head portion. Said rod portion extends through said through-hole and said recess in order to be fixed in the first support and/or in a portion of the luminaire system. The second support is provided with a protruding portion.

The present disclosure provides a safety light. The safety light includes a top housing; a printed circuit board assembly coupled to the top housing, the printed circuit board assembly having a top surface and a bottom surface; a plurality of light elements coupled to the bottom surface of the printed circuit board assembly, the printed circuit board assembly programmed to energize the plurality of light elements following depression of a first control button; a lens coupled to the bottom surface of the printed circuit board assembly and the plurality of light elements, the lens having a first angled reflective surface and a plurality of side surfaces; and a bottom housing coupled to the lens.

A holding device of a lighting module of a lighting unit of a vehicle, comprising a securing section for securing the holding device to the rest of the lighting module and a bearing section for supporting the holding device on a bearing pin of the lighting unit, wherein the bearing section has at least one lock which forms a locking connection together with the bearing pin when the holding device is assembled, and wherein the lock is designed such that the locking connection simultaneously forms a joint which enables the lighting module to rotate about a longitudinal axis of the bearing pin. A lighting module and a lighting unit of a vehicle are also provided.

The invention provides a luminaire (200) comprising a hollow light transmissive body (210), an LED assembly (100) comprised by the hollow light transmissive body (210), and a first end cap (220) closing the hollow light transmissive body (210) at a first end (211) of the hollow light transmissive body (210) and functionally coupled to the hollow light transmissive body (210); wherein (i) the LED assembly (100) is functionally coupled to a connector part (132); (ii) the first end cap (220) is functionally coupled to a complementary connector part (222), complementary to the connector part (132); and (iii) the LED assembly (100) and the first end cap (220) are associated with each other through the connector parts (132, 222), while allowing a translational movement of the LED assembly (100) along a longitudinal axis (115) relative to the hollow light transmissive body (210).

A lamp module group can include a housing defining a first housing end and a second housing end, the housing defining a first protruding column at the first housing end, the housing defining a cavity with a housing opening to the cavity defined at the second housing end and a column opening to the cavity defined by the first protruding column; an LED lamp board positioned within the cavity, the LED lamp board configured to emit light through the housing opening; a power supply driving module positioned within the cavity between the LED lamp board and the first protruding column, the power supply driving module connected in electrical communication with the LED lamp board; and a concentric terminal extending through the column opening, the concentric terminal connected in electrical communication with the power supply driving module.

Provided is a custom printed, side and/or back lit with a LED lighting system (referred to as INK LITES) that can be used as a hard wired device as well as a battery powered mobile unit. More specifically, our custom printed LED lights (INK LITES) can be used as a wall decoration, desk light, ceiling light, mobile light for a vehicle, or mobile light used in a personal backpack. Custom and licensed images are printed in the removable, translucent acrylic insert, which can easily be exchanged throughout the lifetime of the lighting system. The screw in pegs on the back of the light can be used to support the desk light in a horizontal or vertical position or removed so that the light can be placed on the wall. When used with the motion sensor and battery pack, it's a night light that turns on via motion sensor or thru the light sensor that can be adjusted based on the consumers desired preferences. The light can be powered by a standard plug with direct current, the attached 12 volt battery, or a larger eight hour plus rechargeable battery that fits in the vehicle or backpack.
