A display device includes first and second display modules and first and second turning pieces that include a first coupling piece, a first turning piece, a second turning piece, and a third turning piece, a second coupling piece and a guiding device. When the first and second display modules are switched between folding and unfolding, the first turning piece pivots relative to the first coupling piece and the second turning piece, and the third turning piece pivots relative to the second coupling piece and the second turning piece. When the display module is switched from folded to unfolded, the other side of the first display module relative to the side is pulled, the side of the first display module is guided by one end of the guiding device and slides to the other end, the first and second display modules are symmetrically unfolded with the side edge as the center.

Multi-directional multi-joint turning piece and display device thereof

The present invention provides a multi-directional multi-joint turning piece and a display device including the multi-directional multi-joint turning piece. The multi-directional multi-joint turning piece is configured to connect a first display module and a second display module to provide a first display module unfolded or folded with the second display module. The multi-directional multi-joint turning piece includes a first coupling piece, a first turning piece, a second turning piece, a third turning piece, and a second coupling piece, wherein the first coupling piece is connected to the first display module, the second coupling piece is connected to the second display module, the first coupling piece is pivoted to the first turning piece, the first turning piece is pivoted to the second turning piece, the second turning piece is pivoted to the third turning piece, and the third turning piece is pivoted to the second coupling piece.

The present invention relates to a light-emitting apparatus, which comprises at least one reflective housing, at least one light-emitting module, and a reflective member. The reflective housing includes a housing body and a curved surface part. The curved surface part is located on the housing body. The light-emitting module is located below the reflective housing. The light-emitting module includes a light guide plate and at least one light-emitting device. The light-emitting device is located on one side of the light guide plate. The light guide plate includes a plate body and a hole. The hole corresponds to an opening on the curved surface part and is located on the plate body. The reflective member is located below the light-emitting module. The reflective member includes a body and a light-emitting hole. The light-emitting hole corresponds to the hole and located on the body.

Light-emitting apparatus

The present invention relates to a lamp structure, which comprises a light guide plate, a lamp plate, and a lamp housing. The light guide plate includes an inner loop, an outer loop, and an annular tortuous structure. The annular tortuous structure includes a plurality of top recesses and a plurality of bottom recesses. The plurality of top recesses and the plurality of bottom recesses are interlaced to give a continuous concave-convex structure. The lamp plate is disposed inside the inner loop. The lamp housing includes a top housing member and a bottom housing member. The top and bottom housing members are located on both sides of the lamp plate and disposed on the two loop openings of the inner loop and opposing to each other. Thereby, the light of the lamp plate illuminates outward via the shape and structure of the light guide plate.

A system and method for driving LED vehicle lights is provided, for diving an LED taillight and brake light, an LED reversing light and an LED direction indicator. The system and method uses direction indicator controller to receive the direction indicator enabling signal generated by vehicle light power controller and generate an direction indicator control signal to an enabling switch controller to avoid the flasher frequency of the direction indicator from being affected by the lighted taillight and brake light and reversing light so as to provide the driving capability that can stabilize the flasher frequency of the direction indicator.

System and method for driving LED vehicle lights

A method and system for LED calibration is provided for a plurality of LED modules cascaded in a series. Each LED module includes a plurality of LEDs, a driver and a controller. The control signal from a calibration host is transmitted to all the modules to light all LEDs in the LED module. Through the controller of the LED module, the calibration data transmitted from the calibration host is stored in the memory inside the driver so that all the LEDs will emit light according to the calibration. The present invention improves the uniformity of the light emission and improves the module maintenance convenience.

Method and system for LED calibration

A digital lighting control system for controlling a plurality of lighting elements is provided, including a PC, a signal control unit, a signal conversion unit, and a signal dispatching unit. The signal control unit has a video signal input decoder for receiving video signal input and a PC display interface for connecting to the PC. The PC can control the lighting elements through the addresses of the lighting elements stored in the signal control unit. The signal conversion unit is connected to the signal control unit to receive control signals. The received control data is converted into data including addressing and control codes of the lighting elements. The signal dispatching unit is connected to the signal conversion unit for receiving converted addressing and control codes of the lighting elements. The signal dispatching unit dispatches the address and control code to lighting elements, which are connected to the signal dispatching unit. In addition, a plurality of signal control units can be serially connected to a PC, a plurality of signal conversion units can be serially connected to a signal control unit, and a plurality of signal dispatching units can be serially connected to a signal conversion unit. Therefore, a large area or various combinations of lighting elements can be controlled by the digital lighting control system.

Digital lighting control system

A structure for a high diffuse efficiency and water-proof lighting device is provided, including a light tube and a base holder. The light tube and the base holder are each an enclosed structure. The light tube includes a circuit substrate inside the enclosed structure. The circuit substrate includes a plurality of LEDs. The light tube and the base holder each include two holes close to both ends. When the light tube and the base holder are assembled, the holes match so that the wire connecting the circuit substrate can go through the holes to enter the base holder. A water-proof and highly pull-resistant glue is used to fill the overlapping of the holes. A resilient element is used to connect the neighboring circuit substrates, the resilient element can absorb the deformation caused by the temperature changes so that the light diffusion remains uniform. Therefore, the lighting device can perform well even when operating in an environment with drastic temperature changes.
