Abstract: An LED light module free of jumper wires has a substrate and multiple LED chips. The substrate has a positive side circuit, a negative side circuit, multiple first chip connection portions and multiple second connection portions. The first and second chip connection portions are respectively connected to the positive and negative side circuits, and are juxtaposedly and alternately arranged on the substrate so that a width between each first chip connection portion and a corresponding second chip connection portion is smaller than a width of each LED chip. Each LED chip can be directly mounted on corresponding first and second chip connection portions to electrically connect to the positive and negative side circuits. Accordingly, jumper wires for connecting the LED chips and the positive and negative side circuits can be removed to avoid broken jumper wires occurring when the LED light module is shipped or assembled.

Abstract: An LED area light module has a substrate and a circuit layer and a solder mask layer formed on the substrate. The solder mask layer partially covers the circuit layer for the partially exposed circuit layer to form multiple electrical contacts. An embankment wall is formed on the solder mask layer with a solder mask material for the electrical contacts to be located within the embankment wall. Multiple LED chips are mounted on the solder mask layer within the embankment wall and electrically connected to the electrical contacts. Optically-transmissive adhesive is filled and concentrated within the embankment wall and covers the LED chips by a tension force thereof, and forms an optically-transmissive adhesive layer after congealed. Accordingly, the LED area light module eliminates the use of thick frame made of metal or rubber and steps of manufacturing and mounting the frame to simplify the packaging processes.

Abstract: A tubeless light-emitting diode (LED) based lighting device includes at least one base, at least one LED lighting module, and at least one control circuit. The base includes a heat dissipation body. The LED lighting module is mounted to the base so that the base provides the LED lighting module with the functions of retention and heat dissipation. The control circuit is mounted to the base and is electrically connected to power wiring of the LED lighting module for ON/OFF switching of the LED lighting module and supplying of operation power. As such, a tubeless lighting device that emits light in a power saving manner and is constructed in a volume reduced manner is provided.

Abstract: A multifunctional emergency lighting device includes at least one base formed of a heat sink, at least one LED lighting module, at least one emergency LED lighting module, a power control circuit, and at least one backup power supply device. The LED lighting module and the emergency LED lighting module are both mounted in the base. The power control circuit is connected to the LED lighting module and the emergency LED lighting module for converting AC to DC current for charging the backup power supply device and powers the LED lighting module and the emergency LED lighting module. In case of power failure of the electric main, the backup power supply device supplies electrical power to the power control circuit for powering the emergency LED lighting module in order to activate the emergency lighting of the emergency LED lighting module.

Abstract: A light-emitting diode (LED) lighting device includes at least a base, at least an LED light source, and at least a driver. The LED light source is of a rectangular parallelepiped form and is directly mounted to and packaged on an outer surface of the base. The driver is electrically connected to the LED light source for driving the LED light source to emit light.
