Abstract: A flashlight with a sidelight structure is provided and is for use in illumination in dim environments or at night. A sidelight is peripherally disposed at a predetermined position on the flashlight and emits light in a second direction different from the direction of light emitted from a frontlight of the flashlight such that, depending on the required direction of irradiation, a user presses a frontlight switch to turn on the frontlight or presses a sidelight switch to turn on the sidelight. Therefore, the flashlight provides illumination broadly and flexibly.

Abstract: A pixel structure comprising an N-side light emitting surface, several reflectors and several light emitting elements is provided. N is a nature number equal to or greater than 3. The light emitting surface has a first normal line. The reflectors surround peripherals of the light emitting surface. Each reflector, which correspondingly connects with a side of the light emitting surface, is connected to its adjoining reflectors and comprises a first reflecting portion and a second reflecting portion having a second normal line and a third normal line, respectively. The second and the first normal lines intercross to form an acute angle ?, and the third and the first normal lines intercross to form an obtuse angle ?. The lights emitted by the light emitting elements are reflected by the second reflecting portion of the reflectors so that the lights are directed towards the light emitting surface.

Abstract: The present invention provides an anti-opening structure of a lighting device. A recess area preset at a lower portion under an external thread section formed at a lighting source main body is disposed with a restraining member. A hole preset at a lower end of an internal thread section, formed inside of a cap, combines with a nut to allow a screw to be screwed out through the nut outwards the cap. The screw is formed with a projecting circular portion. The cap screwing into the end of the lighting device main body is configured with the anti-opening structure. The screw is screwed into the restraining member by inserting an end of a tool into the screw protruding out of an outside of the cap. The screw is unable to screw in when the projecting circular portion abuts against the restraining member to provide the cap with the anti-opening structure.

Abstract: A waterproof-breathable structure for a flashlight includes a housing and a ventilative plug. The housing is penetrated by a hole with one or more chamfered segments, and the ventilative plug has an outer diameter greater than the hole to be closely fit therein. The ventilative plug has a capping portion, an abutting flange extending from an outer part thereof, and a rim extending from an inner part thereof. Thereby, inner pressure generated in the flashlight due to battery oxidation over time is allowed to escape through an interval formed between an inward retracted periphery of the ventilative plug and the chamfered segments formed at the inner periphery of the housing hole, while the ventilative plug closely fit in the hole of the housing of the flashlight serves to effectively prevent external moisture from incursion.
