The laser device includes a substrate, a laser element disposed on the substrate for emitting a laser light ray, a light guide member disposed on the substrate, and a wavelength conversion layer. The light guide member is light-transmissible and thermally conductive, and has at least one reflection surface for reflecting the laser light ray from the laser element so as to change travelling direction of the laser light ray. The wavelength conversion layer converts wavelength of the laser light ray from the light guide member to result in a laser beam, and contacts the light guide member so that heat from the wavelength conversion layer is transferred to the substrate through the light guide member.

Laser device and light guide member used with the same

A light apparatus for generating a mixed light output. The light apparatus includes multiple LED modules. Each LED module includes multiple LED regions. The multiple LED regions have separate electrodes. The multiple LED regions share the same package housing but at least two LED regions are covered with different fluorescent layers for emitting lights with different optical characteristics.

A hybrid light emitting device includes a full-wave bridge rectifier, an AC-to-DC converter, a hybrid illumination module, a luminance control module and a linear constant current circuit. The full-wave bridge rectifier transforms a full sinusoidal wave voltage into a positive half sinusoidal wave voltage. The AC-to-DC converter is electrically coupled to the full-wave bridge rectifier. The AC-to-DC converter transforms the positive wave voltage into a constant DC voltage. The hybrid illumination module includes a plurality of illuminating elements having different or partially same luminance properties. The plurality of illuminating elements are disposed in respective proximities. The luminance control module generates a plurality of control signals that determine the duty cycles of the plurality of illuminating elements. The linear constant current circuit controls duty cycles of the plurality of illuminance elements using the plurality of control signals.

A packaged illuminating device includes a hybrid light emitting device, a first plurality of bonding wires, a linear constant current circuit, a soldering plate, a second plurality of bonding wires and a protection layer. The hybrid light emitting device includes a plurality of illuminating elements having different or partially same luminance properties. The plurality of illuminating elements are disposed in respective proximities. The linear constant current circuit is electrically coupled to the hybrid light emitting device via the first plurality of bonding wires at a first plurality of pins of the linear constant current circuit. The linear constant current circuit powers up the plurality of illuminating elements using a constant DC voltage and controls duty cycles. The protection layer encapsulates the hybrid light emitting device, the first plurality of bonding wires, the linear constant current circuit, and the second plurality of bonding wires with the aid of the soldering plate.

Packaged illuminating device

A director's chair includes two support frames and two cross rod assemblies connected to the front ends and rear ends of the two support frames. The director's chair is folded or unfolded by controlling support rods of the cross rod assemblies to be folded or unfolded. The height of the folded director's chair is only the height of leg rods of the support frames. An armrest rod, a seat rod and a backrest rod of the support frame can be folded at the side of the leg rods, so that the size of the director's chair is small enough to facilitate the storage and transportation.
