Abstract: An electronic face mask control system includes an electronic face mask. The electronic face mask includes an LED screen configured to display images, a first driving device configured to control an operation of the LED screen, a first detecting device connected with the first driving device, and a first storage device connected to the first driving device. The first detecting device is configured to detect control signals. The first storage device is configured to storage local data. By performing signal detection on the first detecting device, a display content controlled by the first driving device is changed, and a display content of the LED screen is changed.

Abstract: A half-round zipper is provided, including chain teeth, top stops and teeth stringers. Each of the chain teeth has a tooth root provided with a left tooth and a right tooth curved with respect to each other, and has a tooth top provided with an engaging boss and an engaging groove which are arranged respectively on both sides of the tooth top and configured to be engagable with each other, and has an arc-shaped longitudinal cross-section with the center angle of a right angle. Two of the chain teeth are engaged with each other to form a half-round shape. Each of the top stops includes an upper end portion with an arc cross-section and a lower end portion with a horizontally or obliquely flat bottom surface, and is engaged to the inner side of the respective one of the teeth stringers by means of a first holding groove.

Abstract: Embodiments of the present invention generally relate to an integrated compact fluorescent reflector flat panel lamp. In one aspect, an integrated compact fluorescent reflector flat panel lamp is provided. The integrated compact fluorescent reflector flat panel lamp includes a housing, a flat panel lamp portion disposed in the upper part of the housing, lamp circuitry/ballast disposed in the lower part of the housing and a screw type base.

Abstract: Embodiments of the present invention generally relate to a fluorescent flat panel lamp. In one aspect, a flat panel lamp is provided. The flat panel lamp includes a substantially flat glass plate. The flat panel lamp further includes a formed plate attached to the substantially flat glass plate. The glass plates are hermetically sealed and define a channel. The channel is configured to hold gas and mercury. The flat panel lamp further includes an electrode at each end of the channel, wherein a ratio of the active area of the channel to a surface area of the electrode is less than 10.

Abstract: An apparatus for fixing an LED light engine includes a lamp fixture base with a fixing seat, a light emitting module with a basal seat having a light source, a heat dissipating module with a plurality of heat dissipating fins having an embedding groove concavely formed at laterals of the heat dissipating fins and the heat dissipating module being installed around the light emitting module and provided for dissipating heat, a fixing device with first and second fixing elements coupled to the heat dissipating module, and the first and second fixing elements being embedded into the embedding grooves and having at least one fixing plate installed at edges of the first and second fixing elements and fixed to the fixing seat, so as to fixing the heat dissipating module with the lamp fixture base quickly and easily, while overcoming the repair and maintenance problems and providing an excellent practical application of an LED lighting device.

Abstract: An external electrode surface emission fluorescent lamp for LCD backlighting includes (a) a serpentine-shaped upper sheet having a section for maximizing brightness uniformity within a predetermined distance from its surface; (b) a plate-shaped lower sheet combined with the upper sheet to form mutually connected channels; (c) external electrodes installed on surfaces of both ends of the upper sheet; and (d) auxiliary electrodes installed along the surface of channels.
