A light-emitting diode (LED) streetlight structure, which includes a light-emitting module, a power module, and a lamppost. The light-emitting module is disposed on side of the power module; the lamppost is disposed on the other side of the power module and corresponds to the light-emitting module. A heat-dissipating structure is disposed on the surface of a housing of the power module. The heat-dissipating structure corresponds to a power supply in the power module, and can dissipate the heat generated by the power supply and reduce the temperature thereof. Accordingly, heat dissipation of the power supply is enhanced, and hence increasing its lifetime.

An adjustable LED display module is provided, including a plurality of light-emitting units, and at least a set of spacing adjusting mechanism. The spacing adjusting mechanism is of a retractable grid-like structure or a retractable mesh-structure. The plural light-emitting units are distributed on different locations of the components of the spacing adjusting mechanism. When the spacing adjusting mechanism operates to adjust the spacing, at least spacing between some neighboring light-emitting units will change so that the location after adjustment will vary. Hence, the display module will have different form factor and light dots arrangement to provide higher flexibility for various application environments and conditions as well as convenience for storage and transportation when contracted.

The present invention is a digital lighting system controller with video input capability. The present invention provides both an interface for video input and VGA input, and can also be used with standard DMX-512 interface. Therefore, the present invention of a lighting system controller can be used both in lighting systems with standard DMX-512 interface, and regularly or irregularly arranged lighting systems without pre-defined address. In other words, the present invention has the versatility to be used in lighting systems with both types of lighting bulbs or dots.

Digital lighting control system with video input

A smart light emitting diode cluster and system includes a central processing unit (CPU) and a plurality of LED cluster strings, each comprising a plurality of LED cluster connected in series. Each LED cluster includes an LED drive circuit and a plurality of LEDs. The CPU receives external input image signal, and then desired control signal and image data are sent to the LED cluster strings by appropriate processing. The control signal is used to switch the LEDs in the cluster to generate desired image and related color variation. The control signal and image data are transferred to the next LED cluster by the present LED drive circuit. In this manner, the control signal and image data are progressively transferred from the first to the last cluster so that a whole image with color variation can be displayed by all the LEDs in the system.
