Embodiments consistent with the present disclosure provide an LED lighting device and speaker. The LED lighting device and speaker may include an LED lighting unit, a speaker, an outer casing, and a power supply module. The LED lighting unit and the speaker are placed on the outer casing. There is also a sound guiding tube on the outer casing. The sound guiding tube on the outer casing may expand the audio bandwidth, enhance bass quality, reduce speaker vibration displacements, and protect the speaker. Further, the gap between the sound guiding tube and the bottom of the outer casing provides a heat dissipation path for the heat generated by the power supply module. In addition, the sound guiding tube and the hollowed lampshade forms a path that increases the air circulation between the interior and exterior of the LED lighting device and speaker. Finally, the sound guiding tube adds to the heating dissipating surface of the LED lighting device and speaker and therefore improves the efficiency of heat dissipation.

LED lighting device and speaker

Embodiments consistent with the present disclosure provide a multifunctional LED device and a multifunctional speaker system. The multifunctional LED device includes a power supply unit configured to supply power; a control unit configured to process audio signals and control signals; a speaker configured to play audio signals, an audio power amplifier configured to drive the speaker, a wireless transceiver configured to receive and send data, and an LED lighting unit. Further, the wireless transceiver may communicate with both remote smart terminals and other multifunctional LED devices. The multifunctional speaker system may include several multifunctional LED devices and a smart terminal. The smart terminal may communicate with all the multifunctional LED devices. The multifunctional LED devices may communicate with each other. Two of the multifunctional LED devices may form a 2.0-channel speaker system. Other speaker systems such as 2.1-channel, 5.1-channel, 7.1-channel, speaker systems etc., may also be realized by using more multifunctional LED devices. Embodiments consistent with the present disclosure are easy to install, require little wiring, and do not require adding a separate wireless transceiver, or a separate remote control unit or a light switch. Embodiments consistent with the present disclosure support wireless lighting control and provide efficient indoor lighting.

The invention relates to a portable electric lamp with a light source generating at least one light beam; and a pane of glass arranged in front of the light source. The pane of glass has an electro-optical diffusion device controlled by an electrical signal in order to generate electrically adjustable diffusion. This diffusion generates a light beam with variable geometry from the single narrow beam. This results in headlamps with improved control of the geometry of its lightbeams.

Portable Lamp Fitted with Electric Control of the Geometry of the Beam

A remote control system is used for remotely controlling controlled devices. The remote control system includes an input device and a data process device. The input device includes a first communication device. The data process device includes a second communication device for communicating with the first communication device, a storage unit storing an identification table, a controller, and a transceiver. The controller determines whether the data process device receives a control signal from the input device, the control signal including an identification of the input device. When receiving the control signal, the controller determines if the identification of the input device is stored in identification table. The controller outputs a code signal corresponding to the control signal if the identification of the input device is stored in the storage unit. The transceiver receives the code signal and transmits the code signal to a specific one of the controlled devices.

Remote control system and method

Provided is a lighting apparatus which may include an audio system, a light emitting device including a plurality of LEDs, a communication module to receive data for the audio system or the light emitting device, a switch provided between the communication module and the audio system to control a connection between the communication module and the audio system, and a controller to control the audio system and the light emitting device. The controller may be configured to determine whether the received data is associated with the lighting emitting device or the audio system, and controls the switch to connect to the audio system when the received data is associated with the audio system.
