A stage light free from damage of sunlight includes a light body and a control assembly, and a light avoiding system. When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action. According to the present invention, smart light avoiding according to a sunlight status can be achieved by means of a light avoiding system. The light avoiding system has advantages of a high automatic recognition level, a flexible access system, and being cost-effective and easy to implement.

Methods, devices, and systems for airfield luminaire vibration monitoring are described herein. In some examples, one or more embodiments include a computing device comprising a memory and a processor to execute instructions stored in the memory to receive a vibration signal from a sensor on an airfield luminaire, compare the vibration signal from the sensor to a vibration profile for the airfield luminaire, and determine a status of a bolt of the airfield luminaire based on the comparison.

An exemplary lantern comprising a breakaway handle mechanism that allows the handle of the lantern to break away from the body of the lantern. An exemplary lantern may comprise a ratcheting mechanism that allows the handle to rotate relative to the body of the lantern, thereby allowing the lantern to be arranged on the ground in a variety of different positions. An exemplary lantern may comprise a reflector that is specifically designed to increase the far beam throw of light relative to conventionally known lanterns.

A childproof light switch cover apparatus for preventing a child from accessing a light switch includes a cover plate configured to engage a standard light switch box. The cover plate has a switch aperture extending therethrough that is dimensioned to receive a switch of the standard light switch box. A tubular extension is coupled to the cover plate around the switch aperture. A locking tab is coupled to a sidewall of the extension adjacent an outer threaded portion of the extension. A cap has a main portion and a flanged bottom portion. The cap is threadingly engageable with the outer threaded portion of the extension and the flanged bottom portion is selectively engageable with the locking tab to prevent the cap from rotating to disengage from the extension. The locking tab is substantially flexible to be depressed and to allow the cap to rotate freely.

A light bulb apparatus includes a bulb shell, a light source module, a bulb head, a bottom pin and a driver module. The bulb shell has a light passing cover and a neck portion. The bulb head has a body portion and an Edison cap. A bottom pin is used for connecting a second electrode of the Edison socket. The driver module is enclosed by the bulb head. The driver module has a driver plate mounted with a driver component and a driver input terminal. The driver input terminal has a guiding groove. The driver input terminal has a first wiring clip, the bottom pin is inserted into the guiding groove via the entrance and engages the first wiring clip for electrically connected to the driver component.

A linear light-emitting diode (LED) lamp comprising a normally-operated portion and an emergency-operated portion is used to replace a luminaire operated only in a normal mode with alternate-current (AC) mains. The normally-operated portion comprises a fly-back converter whereas the emergency-operated portion comprises a rechargeable battery, a bidirectional circuit, a boost converter, a self-diagnostic circuit, and a control circuit. The linear LED lamp can auto-switch from the normal mode to an emergency mode according to availability of the AC mains and whether a rechargeable battery test is initiated. The bidirectional circuit is configured to convey a forward electric current and a reverse electric current to and from the rechargeable battery, respectively. The self-diagnostic circuit is configured to provide multiple sequences and to auto-evaluate battery performance according to the multiple sequences. During an auto-evaluation period, a terminal voltage on the rechargeable battery is examined with test results displayed in a status indicator.
