The present invention provides a light-emitting diode (LED) device and a method for manufacturing the same. The LED device comprises: a substrate (1); a chip (2) disposed on the substrate (1); and a first lens (3) disposed on the substrate (1) and spaced from the chip (2); wherein the first lens (3) comprises luminescent powder (7) and at least one of light-diffusing particles (8) and light-reflecting particles (10). The LED device provided by the present invention has a high luminous efficiency, and solves the problem in the prior art that the LED device has a small angle of emergence and the emergent light emergence lacks of uniformity.

An ornamental device including a decorative plated surface and a backlit assembly is described, and includes a light engine including a light-emitting diode (LED), a light pipe optically coupled to the LED, a light diffuser and a lens assembly. The lens assembly includes a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate. When the LED is not illuminated, the lens assembly exhibits a chrome appearance, and when the LED is illuminated, light emanates through the lens assembly.

A lighting device (1) is provided comprising at least one light source (3), a wavelength converting element (8) adapted to convert a wavelength of light emitted by the at least one light source, at least one support (7) arranged to support the wavelength converting element remote from the at least one light source, and an envelope (2) adapted to enclose the wavelength converting element and at least a portion of the at least one support. The at least one support is arranged to be able to pivot relative to the wavelength converting element. The present lighting device enables using a rigid wavelength converting element and an at least partially rigid support, as these two components may be moved relative to each other for facilitating insertion of the unit in the envelope.

A light diffuser includes: a thermoplastic resin base which has a thermal expansion coefficient of at least 4×10.sup.−5/K and at most 8×10.sup.−5/K; and a light diffusion layer which is disposed on a surface of the thermoplastic resin base and includes an acrylic resin film and an acrylic resin particle, the acrylic resin film including one or more acrylic resins having a glass transition temperature of at least 30° C. and at most 50° C., the acrylic resin particle being included in the acrylic resin film and having an average particle size of at least 1 μm and at most 15 μm.

The present invention relates to a lighting device for creating a light beam comprising a light source and an optical element positioned along an optical axis (80) between said light source and an outlet for said light beam wherein said optical element comprises an at least partially transparent or translucent effects wheel (1), said effects wheel (1) being movable between a first active position in which the effects wheel (1) is positioned along said optical axis (80) and a second inactive position, in which the effects wheel (1) is positioned outside said optical axis (80), and actuation means suitable for moving the effects wheel (1) in a back-and-forth movement between its first active position and its second inactive position.

A laundry treating apparatus is disclosed. The laundry treating apparatus includes control panel body that defines an opening with a circular perimeter and a diameter. The laundry treating apparatus further includes at least one light source. The laundry treating apparatus further includes a rotary knob that is configured to manipulate a rotary switch and that has an outer circumferential surface that is spaced apart from the circular perimeter of the opening to define a clearance between the rotary knob and the control panel body. The laundry treating apparatus includes further a knob decorative member that is located between the rotary knob and the circular perimeter of the opening. The laundry treating apparatus further includes a window that includes a light transmission portion through which light emitted from the at least one light source passes.

A lighting device with a lighting function includes a coating layer coated onto the outer surface of a main body, and the coating layer is made of an antiviral material, so that the main body of the lighting device is coated with an antiviral material mainly composed of titanium dioxide and nanosilver to provide the self-cleaning and deodorizing effects, and the advantages of resisting viruses and bacteria, removing pollutants from the environment, and preventing mildews and algae effectively.

The present invention relates to a lamp (1), comprising a lamp base (3), a semi-reflective envelope (2), at least one first solid state light source filament (4a-d) arranged inside the semi-reflective envelope (2), and a second solid state light source (5) arranged inside the semi-reflective envelope (2), wherein the reflectivity of the semi-reflective envelope (2) is in the range from 30% to 70% for light emitted by the at least one first solid state light source filament (4a-d) and the second solid state light source (5), wherein the at least one first solid state light source filament (4a-d) is arranged at a first distance lower than 7 millimeters from the semi-reflective envelope (2), and wherein the second solid state light source (5) is arranged at second distance higher than 15 millimeters from the semi-reflective envelope (2).
