摘要： A lighting apparatus includes a lens, a cup housing, a light source and a top cover. The cup housing has a surrounding wall and a light source holder. The cup housing is installed on a fixed platform. The light source is placed on the light source holder. The cup housing and the top cover form a container space for storing the lens and the light source. A top end of the lens is attached to the top cover. A second end of the lens faces to the light source. A relative distance between the lens and the light source is adjustable to change a light pattern of a output light of the light source. The output light is a light of the light source passing through the lens.

摘要： A light emitting device includes multiple light source parts each including at least one first light source part and at least one second light source part, each including a light emitting element and a light-guiding member to guide light of the light emitting element. Each light-guiding member has a taper shape narrowing toward the light emitting element. Light from each light source part satisfies condition of θ≤α≤tan−1×2 tan θ. (θ is an angle of a straight line connecting a position on the light-irradiation surface having an illuminance of at least one-half of that at center position and the center of the light emitting surface of the first light source part, and α is an angle of a straight line connecting a center of a light-irradiation region on a light-irradiation surface and a center of the light emitting surface of the second light source part.)

摘要： There is presented a lighting device comprising: several light-emitting filaments (15, 15′) with solid-state light sources and a circuit board (10) with first and second electrically conductive tracks (13, 14) following first and second paths, respectively. Each light-emitting filament (15, 15′) comprises a first electrical contact (19, 19′) electrically connected to the first track (13) at a first point on the first path, and a second electrical contact (20, 20′) electrically connected to the second track (14) at a second point on the second path. The first and second points associated with each light-emitting filament (15, 15′) are arranged on an axis (A) which is non-perpendicular to a tangent (T1) to the first path at the first point and to a tangent (T2) to the second path at the second point. The lighting device may be adapted to emit light from what appears to be a surface according to an observer.

摘要： An LED lamp and a power supply module thereof are provided. The power supply module includes a driving circuit, a OVP circuit, and an impedance detection circuit. The OVP circuit is configured to determine whether an OVP condition is detected by sampling the driving signal, and the impedance detection circuit is configured to determine whether a user touching state is detected. When either the OVP condition or the user touching state is detected, the power switch of the driving circuit will be controlled to limit the amount of a current flowing through the power switch. In addition, the impedance detection circuit could detect the user touching state by comparing signals with a defined level sampled during each pulse, thus enhancing the detection accuracy.

摘要： Light-emitting diode (LED) packages, and more particularly broad electromagnetic spectrum LED packages are disclosed. Individual LED packages are disclosed that are capable of emitting various combinations of peak wavelengths across a broad electromagnetic spectrum, including one or more combinations of ultraviolet, visible, and infrared peak wavelengths. Such LED packages may also be broadly tunable across portions of the electromagnetic spectrum ranging from ultraviolet to infrared wavelengths. By providing such capabilities within a single light source provided by a single LED package, larger and more complex systems for broadband emissions that include multiple light sources, complex optical systems, mirrors, filters, and additional components may be avoided. LED chip arrangements, control schemes, and encapsulant arrangements are also disclosed for such broad electromagnetic spectrum LED packages.

摘要： A low-profile recessed light fixture has a housing with a low height and forming a light engine enclosure with an aperture. A light engine assembly within the light engine enclosure as a heat sink assembly and a light emitting element. The heat sink assembly has first and second heat sinks, and the light emitting element is mounted to the first heat. The first heat sink is operable to tilt relative to the second heat sink about a tilt a tilt range. The light engine assembly is operable to translate between an operation position and an offset service position. In the operation position at a zero tilt an optical axis of the light emitting element is substantially parallel to a vertical axis passes through a center of the aperture. The light engine assembly being operable to rotate relative to the housing through a rotation range of at least 360 degrees.
