Abstract:
An illumination device power control module is capable of dynamically adjusting power consumption of a light-emitting diode (LED) illumination device by adjusting the output voltage to different levels to control the power of the light emitting diode illumination device. An alternating current power source terminal is configured to receive an alternating current voltage. A rectifier is configured to convert the alternating current voltage to a rectified voltage.
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.

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.

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.

The protective cover includes a first housing and a second housing. The first housing includes a first engaging portion and the second housing includes a second engaging portion corresponding to the first engaging portion. When the second engaging portion engages with the first engaging portion, the first housing contains the lamp base assembly cooperatively with the second housing, and a surface of the lamp base assembly respectively is separated from a surface of the first housing and a surface of the second housing by a distance.
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 light emitting device includes a frame, a plurality of first light emitting units and a plurality of second light emitting units. The frame includes a base, a plurality of first pillars and a plurality of second pillars, wherein the first pillars and the second pillars are extended from a periphery of the base and arranged interlacedly, the first pillars are bent inwardly with respect to the base, and the second pillars are bent outwardly with respect to the base. Each of the first light emitting units is disposed on one of the first pillars. Each of the second light emitting units is disposed on one of the second pillars.
Abstract:
A planar light apparatus is disclosed and includes a reflection part, a secondary optic device, and a light-emitting device. The secondary optic device has a light incident surface, a light emitting surface, and a side surface, which is an elliptic surface, between the light incident surface and the light emitting surface. A reflecting surface of the reflection part and the light emitting surface face a void space formed between the secondary optic device and the reflection part. Light beams emitted by the light-emitting device into the secondary optic device through the light incident surface can be reflected by the side surface to emit out of the secondary optic device through the light emitting surface into the void space to be reflected by the reflecting surface. Thereby, the planar light apparatus without a conventional light-guiding plate still can offer a planar light source with certain uniformity and can be structured thinner.
