A connection device according to an embodiment disclosed herein is a connection device connected to a flexible lighting device and includes a body part, a connection terminal protruding toward the flexible lighting device from the body part and electrically connected to the flexible lighting device, a lighting device guide part provided to protrude toward the flexible lighting device from the body part, configured to guide the flexible lighting device to be inserted into the connection device and having one or more side surfaces provided to be open, and a clip part coupled to an outer side of the lighting device guide part at one open side surface of the lighting device guide part and provided to be fixed to one side surface of the flexible lighting device, which is exposed to the outside due to the one open side surface.

A linear lighting system and apparatus configured for easy and efficient installation and to reduce unattractive shadows, gaps, or light leaks is provided. In certain embodiments, the linear lighting system comprises a plurality of lighting assemblies joined contiguously together with a draw latch assembly and each of the lighting assemblies comprising a housing, a light source, and a power source. More specifically, the draw latch assembly comprises a draw latch and a latch keeper which, when engaged, removably secures a first lighting assembly to a second lighting assembly. In use, there may be more than two lighting assemblies which may be removably secured to one another in this manner in a variety of configurations.

Devices and methods for optical-based tamper detection using variable light characteristics are disclosed. In one embodiment, an electronic device may include a housing, a light source within the housing configured to emit light having an output light characteristic that is variable, a light detector within the housing configured to receive the light emitted by the light source, the light received by the light detector having a received light characteristic, and an optoelectric controller in communication with the light source and the light detector, wherein the optoelectric controller controls the output light characteristic, and compares the received light characteristic to a known received light characteristic.

A support for mounting at least one lighting element on a safety helmet, the support comprising a body having: (i) at least one helmet attaching portion configured for directly or indirectly connecting the support to a portion of the safety helmet, and (ii) a plurality of lighting element attaching portions configured for directly or indirectly connecting the at least one lighting element to the support, wherein the plurality of lighting element attaching portions are configured to facilitate the attachment of the at least one lighting element in a corresponding plurality of positions, such that light projected from the at least one lighting element is focused or directed at a plurality of corresponding angles.

An outdoor area LED lighting system including: a housing containing a large array of LEDs mounted to an aluminum direct thermal path printed circuit board and a single lens. The large array of LEDs are capable of producing light rays directed through the single lens to produce a beam of light to illuminate the outdoor area. The single lens is preferably a Fresnel lens. The housing is preferably capable of being sealed in a weather-tight manner. A second housing may at least partially surround the first housing such that at least one air passage is provided between the first housing and the second housing. A heat sink including a heat block in thermal communication with a plurality of heat tubes and fin assemblies may be in partial thermal contact with the LED module and in fluid communication with the at least one air passage. At least one fan may be provided in or in fluid communication with said at least one air passage to cool the heat sink. A digital interface may connect the LED module to a host computer to monitor and track information and trending for statistical process control.

This device includes an electronic board including a front surface; at least one light emitter assembled on the front surface; a protective cover configured to protect the electronic board and the at least one light emitter; a thermally-conductive resin layer having a heat exchange surface meant to be in direct contact with the aquatic environment, the thermally-conductive resin layer being configured to transfer the heat generated by the at least one light emitter to the heat exchange surface, and configured to ensure the sealing of the protective cover with the heat exchange surface.
