Abstract:
An illumination apparatus includes a light emitting module and a containing base. The light emitting module includes a light guide bar and a light emitting device disposed on an end of the light guide bar. The light emitting device includes a heat dissipating sheet and a light emitting element. The heat dissipating sheet has a first positioning component. The light emitting element is disposed on the heat dissipating sheet for emitting light to the light guide bar. The containing base is used for containing the light emitting module. A second positioning component is formed on a side of the containing base corresponding to the first positioning component. The second positioning component is used for engaging with the first positioning component when the light emitting module is disposed on the containing base, so as to fix a position of the light emitting module relative to the containing base.
Abstract:
A rotatable illumination device includes a first casing, a light emitting module, a first fixing member and a second fixing member. The first casing has a first rotating portion and a first protruding portion is formed on the first rotating portion. The light emitting module is disposed in the first casing. A first indentation is formed on the first fixing member and the first protruding portion can pass through the first indentation. A second indentation and a second protruding portion are formed on the second fixing member and the first protruding portion can pass through the second indentation. The first and second fixing members are fixed together, and the first and second protruding portions are coplanar. The first protruding portion cooperates with the second protruding portion to limit rotating angle of the first casing.
Abstract:
A connection structure of an electronic device includes a circuit board, a plurality of conductive contact pads and a conductive pattern. The conductive contact pads and the conductive pattern are disposed on the circuit board. The conductive contact pads are electrically insulated from one another. The conductive pattern is electrically insulated from the conductive contact pads. The conductive pattern is disposed on at least three sides of the conductive contact pads so as to generate an electrostatic discharge protection effect for the conductive contact pads.
Abstract:
An illumination device comprising a light guide bar, a light source and a reflective sleeve is provided. The light guide bar comprises a first end surface, a second end surface, and a cylindrical surface. The cylindrical surface is disposed between the first end surface and the second end surface and has a light-emitting surface and a reflective surface. The light source is disposed at the outside of the first end surface of the light guide bar. The reflective sleeve covers the second end surface of the light guide bar and has a reflective cavity, which tapers inward to form a vertex angle. A part of the incident light of the light source is reflected to the light-emitting surface via the reflective surface by the reflective cavity or directly reflected to the light-emitting surface by the reflective cavity.
Abstract:
A light source device is disclosed and includes a reflective cup, a light-emitting chip, and a light transmissive substrate. The reflective cup has an opening. The light-emitting chip has a light-emitting layer, a first light-emitting surface, and a second light-emitting surface. The first and second light-emitting surfaces are opposite right to a first side and a second side of the light-emitting layer. The light-emitting chip is disposed inside the reflective cup, such that light emitted from the first and second sides emits out of the light-emitting chip through the first and second light-emitting surfaces respectively to be reflected by the reflective cup to be emitted out of the reflective cup through the opening. Therefore, the light extraction efficiency of the light-emitting chip can be improved.
Abstract:
An illumination apparatus includes a transparent case, an opaque member, a ring-shaped light emitting device, and a ring-shaped transparent cover. The transparent case has a central region. The opaque member is disposed on the central region. The ring-shaped light emitting device is disposed in the transparent case corresponding to the central region. The ring-shaped transparent cover is disposed on the ring-shaped light emitting device and has a first arc-shaped ring portion relatively close to the opaque member and a second arc-shaped ring portion relatively away from the opaque member. A refraction microstructure region is formed on an inner surface of the first arc-shaped ring portion for refracting light emitted by the ring-shaped light emitting device.
Abstract:
An illumination apparatus includes a light emitting device and a fluorescent lamp base having first and second sockets. The light emitting device is disposed on the fluorescent lamp base and includes a light guide bar, first and second plug structures, and a first LED assembly. The light guide bar has first and second ends corresponding to the first and second plug structures respectively. The first and second plug structures are respectively disposed on the first and second ends of the light guide bar for electrically connecting to the first and second sockets respectively. The first LED assembly is disposed in the first plug structure and has two first cables. The two first cables are electrically connected to the first and second plug structures respectively, so as to make the first LED assembly receive power provided by the fluorescent lamp base for emitting light to the light guide bar.
Abstract:
