| 20120044677 | WATERPROOF LED DIFFUSER - An LED waterproof diffuser has an LED substrate housing, a diffusing portion and an embedded locating portion. The housing is of a 3D holding space formed by an end wall and a periphery. An LED inlet is formed at the other end of the periphery. The hollow diffusing portion is protruded from the center of the end wall of the LED substrate housing in a reducing pattern. The embedded locating portion is formed externally onto the diffusing portion, and can also be embedded securely into the hole of an existing shell plate. The diffuser allows one to assemble a single or several LED units, thus reducing the manufacturing cost and realizing excellent waterproofing effects, while enabling partial replacement or maintenance of LED elements. Moreover, since the outer diameter of the diffusing portion is smaller than that of the LED substrate housing, a smaller hole area for assembly can be obtained. | 02-23-2012 |
| 20110234424 | LED WATER-PROOFING DIFFUSER EMBEDDED INTO A SHELL PLATE - An LED water-proofing diffuser embedded into the shell plate, said LED water-proofing diffuser includes an LED baseplate retaining shell, which is a 3D holding space formed by an end wall and a circumferential flange. An LED assembly port is formed at the other end of the circumferential flange. An LED diffusing portion has a hollow shape protruding from the end wall of the LED baseplate retaining shell. The LED diffusing portion is available with light transmittance. An embedded positioning portion is integrally formed onto the exterior of the end wall or circumferential flange of the LED baseplate retaining shell. Said embedded positioning portion can be embedded securely into the hole of existing shell plate. Said LED water-proofing diffuser can be assembled with a single or several LED units, and waterproofing is made possible within the space of the LED water-proofing diffuser. | 09-29-2011 |

The multifunctional integrated dimming controller includes a controller casing having an assembly surface and a terminal coupling portion. A contact block of solar photovoltaic panel is assembled on the coupling portion and connected with the solar photovoltaic panel. A contact block is assembled on the terminal coupling portion and connected with the electrical storage device. An LED contact block is assembled on the coupling portion and connected with the LED unit. An external sensing contact block is assembled on the coupling portion and connected with the external sensor. An integrated electrical control module is accommodated into the controller casing including a circuit board, a dimming processor on the circuit board and an electrical control unit. | 06-30-2011 |
| 20110138663 | MODULAR LED LIGHT-EMITTING MARKER - A modular LED light-emitting marker having a pedestal with a back side, a light-emitting marking side and a holding space. At least a LED circuit board is accommodated into the holding space of the pedestal. The LED circuit board contains a LED setup surface, which faces the light-emitting marking side of the pedestal. The LED circuit board also contains an electrical connecting line penetrating out of the pedestal. A waterproof cladding is assembled between the LED circuit board and the pedestal, and used to fully seal the LED circuit board. A reflecting surface is set onto the light-emitting marking side of the pedestal. The reflecting surface is provided with LED through-holes. A protruding LED unit is arranged onto the LED setup surface The exterior of the protruding LED unit is protruded out of the waterproof cladding and reflecting surface. | 06-16-2011 |
| 20110119975 | MARKING PANEL LED LIGHT EMITTING MODULE - A combined LED light-emitting module of marking panel has a rail-mounted rack, extended longitudinally containing a locating portion for positioning onto the marking panel, and an assembly portion. A plurality of LED light-emitting units are mounted onto the assembly portion in sequence or at interval. The LED light-emitting unit contains a support pedestal, a light-emitting faceplate, a circuit board and at least a light-emitting component on the circuit board. The light-emitting faceplate is sealed into the holding space of the support pedestal. The circuit board is mounted into the holding space and the light-emitting component is allowed to face the light-emitting faceplate. The circuit board is sealed by waterproof element. A limiter is used to limit securely the LED light-emitting units. A quick-release electrical connector, protruded from the back board of the support pedestal contains male and female conductive contacts that can be quickly removed and assembled. | 05-26-2011 |
| 20100271216 | OUTDOOR RAIN FOG DETECTOR SWITCH GEAR - An outdoor rain fog detector switch gear has a hollow housing with roof and wall; an assembly locating portion to assemble and locate the rain fog detector switch gear onto the object; a retaining space; a punch hole to connect the retaining space with ambient environment; a circuit board connected with a power supply line that protrudes out of the housing to connect electrically with the control circuit of the intended electrical device. The circuit board is also connected with a signal line to output a switching control signal or digital detection signal. A moisture probe senses and detects the moisture in ambient environment. The circuit board permits to turn on/off its automatic switching control function depending on the sensing state of the moisture probe. A protective film is covered externally onto the circuit board for waterproofing. The moisture probe is exposed outside of the protective film. | 10-28-2010 |
| 20100101127 | LIGHT EMITTING DIODE (LED) ROAD SIGN PLATE - An improved light emitting diode (LED) road sign plate includes a plate seat, fixed mount, light guide plate, LED lights and graphical text shield. The fixed mount is provided with grooved rail. Several LED lights are embedded into the holding tank, and the light guide plate adhered with graphical text shield is incorporated into the grooved rail. The LED light source emits rays towards the center, and the opening is sealed by the adhesive tape. After being energized, a few LED lights emit light sources for the central graphical road signs, then the light guide plate makes its uniform rays penetrate the graphical text shield for outwards irradiation and clear visualization of the graphical road signs, thus saving the electricity and extending the service life with better assembly. | 04-29-2010 |
