The heat radiating member includes a lower face portion, a side face portion and a rear face portion disposed so as to respectively face a lower face and a side face of the light emitter and the emission control substrate.

The present invention relates to a light emitting accessory for a portable terminal and an accessory light emitting system for a portable terminal, and to a light emitting accessory for a portable terminal, which is detachably coupled to the portable terminal to emit light using light of a flash of the portable terminal based on an external signal, a location of the portable terminal, and the like, and an accessory light emitting system for a portable terminal. A light emitting accessory for a portable terminal according to the present invention includes: a fixing unit that is detachably coupled to a portable terminal to cover a flash that is formed on a rear surface of the portable terminal; and a light emitting unit that receives light of the flash from the fixing unit to emit light.

A method of assembling or disassembling a housing shelf configured at least from shelf plates and frames, including a step in which a chuck holds a frame; a step of determining, based on an image captured by an imager that captures an image of the frame held by the chuck and positioned at an imaged position, a position of a target portion of the frame on the image; and a step of determining, based on the determined position on the image, at least one correction value for causing a change in a release position for the frame when the frame is released from the chuck onto the shelf plate. The target portion may be an inner wall surface of the frame. An illumination unit may be arranged between the imager and the imaged position of the frame.

an external light source is designed as an external flashgun for mobile devices consisting of a xenon flash tube with associated electronic circuitry, whereby the external light source is arranged to operate in at least two modes, in the single flash mode and in the apparent uniform flash mode. The mode of the external light source's operation is set automatically based on the exposure time set on the linked mobile device. One or several external light source are arranged to connect to a mobile device via a radio link, whereby the external light source sends timestamps to the linked mobile device in regular intervals via the radio link. Based on the timestamps, an algorithm in the software running on the mobile device calculates the time delay between the moment photo capture starts on the mobile device and the moment of the flash of light being triggered by the external light source, resulting in the entire frame/subject/scene being uniformly lighted.

An insect trap and a method of using the same. The insect trap includes a housing. The insect trap also includes a glue board receiving space located inside the housing. The insect trap further includes one or more light sources for attracting insects into the housing. The insect trap also includes a camera having a lens. The lens has a front element. The camera is positioned to capture images of a glue board when the glue board is received in the glue board receiving space. There is no line of sight between the or each light source and the front element of the lens. This may prevent light from the or each light source reaching the front element directly. The method can include using an image captured by the camera to determine that a glue board received in the glue board receiving space needs to be replaced.

An accessory strobe device for a mobile device may operate to provide illumination at the same time as an internal built-in strobe (flash) of the mobile device. The accessory strobe device may receive a single, unidirectional signal from the mobile device that provides signals related to the timing of the internal strobe. The accessory strobe device may process the received signal to control its illumination using the timing and relative intensity levels of the internal strobe during metering and main (normal) flash operations associated with a camera on the mobile device. With the accessory strobe device operating using timing and relative intensity levels in a predetermined relationship with the timing and relative intensity levels of the internal strobe, the accessory strobe device may be used to complement the internal strobe during the metering and main (normal) flash operations for the camera.

The invention discloses a lamp with a zoom lens, which comprises the zoom lens and a lamp body, the lamp body is connected with the zoom lens, the zoom lens comprises: a rear fixed group, comprising a first biconvex lens; a zooming group, comprising a first concave-convex meniscus lens and a plano-convex lens; a compensating group, comprising a biconcave meniscus lens and a second concave-convex meniscus lens; and a front fixed group, comprising a second biconvex lens. The four groups are sequentially arranged in the direction of an optical axis; and the lamp realizes zooming by movement of the zooming group and the compensating group in the direction of the optical axis. A change of a pattern or a beam size is realized; the number of lenses is reduced; zooming of the zoom lens is realized only by movement of the zooming group and the compensating group.

A color correction device comprises a light-emission information collection circuit, a first communication circuit and a color correction processing circuit, wherein the light-emission information collection circuit is used for collecting light-emission information of an external flash; the first communication circuit is used for communicating with a terminal device, so as to receive a color correction control instruction sent by the terminal device; the color correction processing circuit receives the color correction control instruction transmitted by the first communication circuit and then performs color correction processing on the basis of the light-emission information to generate color correction result information; and the color correction result information is used for being transmitted to the external flash so as to correct light-emission of the external flash. The color correction device can be used for color correction of the external flash.
