The insulation layer is between the first metal layer and the second metal layer. The wireless circuit electrically connected to the second portion of the first metal layer. The antenna radiation part is used as an antenna for receiving a wireless signal.

The present utility model discloses a downlight that belongs to the technical field of downlights and is suitable for embedded tubes of different specifications; the downlight includes a lamp cup; a drive board is arranged inside the lamp cup, and a light source board is arranged below the drive board; a lampshade is arranged below the lamp cup, and two symmetrically arranged mounts are arranged on the lamp cup; and a spring is rotatably embedded in the mount. The spring of the present utility model can be rotated in the mount along the transverse axle at the bottom of the installation bracket, so as to adjust the relative distance between the two springs, such that one downlight can be applied to the installed embedded tubes of different specifications, thereby saving the cost of manufacturers in inventory storage and reducing the models of downlights purchased by users; the present utility model uses a triangular limit block, which has a horizontal bottom face for limiting the spring and an inclined side face for installing the spring.

Systems, methods, and computer program products for providing and managing a lighting system. A lighting device of the system is configured to receive an activation signal from a user interface of the lighting device, an external communication device, or another lighting device. In response to receiving the activation signal, and if certain operational conditions are met, the lighting device may activate a light source and transmit another activation signal. Additional lighting devices receiving the activation signal from the first lighting device may also activate their light sources and retransmit the activation signal. Data carried by the activation signals and signals received from one or more sensors in each lighting device may be used by the lighting device to determine whether to activate its light source, and one or more characteristics of the light to be emitted.

A hand-held spotlight, having: a housing provided with an accommodating cavity; a power supply box detachably disposed in the accommodating cavity; a switch base connected to the housing and provided with a first clamping block; and a cover body hinged with the housing, wherein the cover body is capable of covering an opening of the accommodating cavity to confine the power supply box within the accommodating cavity, and the cover body is provided with a second clamping block, which is clamped with the first clamping block when the cover body covers the opening of the accommodating cavity, thereby restricting the flipping of the cover body.

An electronic module can include a first housing defining a housing cavity, the first housing defining a first end and a second end positioned opposite from the first end, the first end defined by a shaft of the first housing, the shaft defining external threading, the first housing defining a housing opening to the housing cavity at the second end; an LED lamp board positioned within the housing cavity, the LED lamp board configured to emit light through the housing opening; a power supply driving module positioned within the housing cavity at least partially between the LED lamp board and the shaft; and a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending at least partially through the shaft, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal.
