摘要:
Lighting devices comprising first, second and third strings of solid state lighting devices. One aspect further comprises means for supplying first fixed current through the first string, means for supplying second fixed current through the second string, and means for supplying current through the third string. In a second aspect, the first and second strings emit light within a specific area on a 1931 CIE Chromaticity Diagram, and the third string emits light of dominant wavelength 600-640 nm. A third aspect further comprises a power line and a power supply configured to supply a first and second fixed currents through the first and second strings, respectively, and supply a current to the third string. A method of making a lighting device, comprising measuring color output, adjusting current to first, second and/or third strings, and permanently setting currents to the first and second strings.

A circuit for a lighting device comprises a sub-circuit which comprises a series current regulator and a group of solid state light emitters. The current regulator and the solid state light emitters are arranged in series. In some embodiments, the circuit further comprises a fan electrically connected in series in the sub-circuit. In some embodiments, the circuit further comprises a second sub-circuit which comprises a second series current regulator and a second group of solid state light emitters, the first sub-circuit and the second sub-circuit being arranged in parallel. In some embodiments, an anode of the series current regulator is electrically connected to a cathode of one of the solid state light emitters. Also, methods of lighting wherein a sum of voltage drops across light emitters and a current regulator is in the range of from 1.2 to 1.6 times the line voltage.

Child carriers and methods for operating the same are disclosed. An example child carrier includes a child support pouch to receive a child in a substantially upright position and a harness to support the child support pouch on an adult. The harness includes first and second support straps, first and second waist straps, and first and second support strap connector pairs. The first support strap connector pair is located to releasably connect the first support strap to the first waist strap in a first orientation with the first support strap across a shoulder of the adult and to releasably connect the first support strap to the first waist strap in a second orientation with the first support strap around a waist of the adult. The second support strap connector pair is located to releasably connect the second support strap to the second waist strap.

摘要:
A mattress has an internal support structure and an external cladding that surrounds and covers at least a portion of the support structure. The mattress also has a vibrating device that is coupled to a part of the support structure. The vibrating device has a motor that operates to transmit vibrations throughout the support structure when turned on. The mattress can be adapted to gradually slow at a controlled rate to a complete stop over a period of time when turned off. The mattress can also be adapted to include the vibrating device internally where the device is water resistant. The mattress can also be adapted such that the vibrating device can be easily removed and installed from a pocket provided in the mattress.
