A laser-based light source includes a laser device configured to generate laser light of a predetermined laser wavelength and emit this laser light as a laser beam. A light-conversion device is configured to convert at least part of the laser light into converted light and a laser-output sensor is configured to determine a laser-output signal proportional to the output of laser light emitted by the laser device. Further, a converted-light sensor is configured to determine a converted-light signal proportional to the output of converted light emitted by the light-conversion device. A controller is configured to receive the laser-output signal and the converted-light signal, to determine a safe-to-operate parameter, based on the laser-output signal and the converted-light signal, and to control the operation of the laser-based light source based on a comparison of the safe-to-operate parameter with a at least one predefined threshold.

The present utility model discloses a safety focusing ignition flashlight device, including a cylinder, a housing, and several replaceable-members. The housing sleeves an end of the cylinder, and which extends and retracts axially along the cylinder; a first lens is arranged at a light-outlet of the cylinder, and the light-outlet is spliced with any replaceable-member to form a flashlight device; one replaceable-member includes a first end ring, and the ring and the housing hold the first lens; and another replaceable-member includes a second end ring and a second lens fixed on the second end ring wall, the ring and the housing hold the first lens, light emitted from the light outlet gathers to form an ignition point after passing through the first and second lens by adjusting an extension or retraction distance. By changing the replaceable-members, the flashlight device can provide a normal lighting function and satisfy an ignition requirement.

A new light apparatus (such as LED lamps) and lamp caps (30) for connecting the light apparatus to corresponding lighting fixtures for operation at higher voltages with existing lighting fixtures, by using modified caps (30) comprising groove/gap (32) patterns in the insulating materials of the caps (30). The new and/or improved lighting sources/light tubes operating at a higher voltage using the same interface caps (30) may require a larger minimum creepage distance between power coupling electrodes/pins (22a,22b). This can be accomplished by adding one or more grooves or gaps (32) of predefined dimensions in the electrically insulating materials on surface of cap (30) in a vicinity of the at least two conductive elements/electric pins (22a,22b). The light apparatus utilizing a same or a different lighting technology but operating at a higher operating voltage than the original/legacy light apparatus.

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.
