摘要： 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.

摘要： An optical pest repeller includes at least two first light sources, at least two first photosensitive members, at least one second light source, and a processing unit. The second light source is located between the first photosensitive members in a second direction. By comparing a light-shading area with a threshold value, no matter which side of the second direction a human body enters by mistake, the second light source can be turned off in time. The safety of use of the optical pest repeller is improved greatly.

摘要： A dimmable tamper resistant nightlight may include a body comprising at least one light emitting diode (LED). Plug blades may extend from the body. A dimming switch may be coupled to the at last one LED, the dimming switch configured to move between a first position that activates about 50% luminosity of the at least one LED, a second position that deactivates about 100% luminosity of the at least one LED, and a third position that activates about 100% luminosity of the at least one LED. A housing may be coupled to the body, the housing comprising an access opening through which the dimming switch may be moved among the first position, the second position, and the third position. A housing may also comprise a locking element configured to prevent the dimmable tamper resistant nightlight from being removed from the electrical receptacle.

摘要： Disclosed is a laser-based device for use primarily for laser light effects. The laser device comprises multiple red, green, and blue lasers. Each laser has a lens to collimate and focus each individual beam. The lasers are aligned such that each laser shares a common output axis. The intensity of each laser is adjustable thereby allowing the overall output color of the device to change. The overall output has over 16 million colors. Each laser-based device has a gimbal-like system to allow the devices change their orientation. A remote control system allows for the control and synchronization of multiple devices. Multiple devices may connect to the remote control system using cables, wireless transceivers, or both. Multiple devices may be located in close proximity to create a more powerful overall output beam. The remote control system allows for viewer interaction through an application installed onto a personal communication device.

摘要： An electronic device comprising a lens and a selector ring is disclosed. The selector ring is mounted for rotation about the lens and comprises a plurality of tabs projecting inwards towards the lens which engaging with and are held within a tab receiving groove comprising a plurality of spaced notches. Each of the notches is dimensioned to receive one of said tabs. A wave spring positioned between an annular ledge of the lens and the selector ring which biases the plurality of tabs against the groove and such that when each of the plurality of tabs is positioned adjacent a respective one of the notches, the tabs are biased into the notches thereby preventing said selector ring from being rotated. A user disengages the tabs from the notches by pressing said selector ring against the bias of the wave spring, thereby allowing the selector ring to be rotated.

摘要： The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.
