An amplifier comprising a main branch amplifier and an auxiliary branch amplifier, wherein one branch is a constant current-biased branch, and another branch is a voltage biased branch, with the branches connected in cascode configuration to form a load modulated amplifier.

High efficiency ultra-wideband amplifier

A Light-Emitting Diode (LED) light apparatus has a housing and a printed circuit board (PCB) received in the housing. The PCB has one or more first openings and one or more LEDs on a front side thereof about the first openings. The housing has a rear-wall structure with a plurality of fins spaced from each other and one or more second openings at locations corresponding to those of the first openings for heat management. The LED light apparatus may also have a plurality of rotatable LED panels having PCBs and LEDs thereon. The LED panels are spaced from each other with gaps therebetween for heat management, and are rotatable for controlling light distribution, light angular-span, and light direction. A LED grow-light system uses a light-distribution structure such as reflectors and/or fiber-optic cables for distributing at least a portion of the light towards the plant.

High-performance high-power LED lighting systems and methods thereof

A lighting system has a power source formed by a solar panel and a battery assembly, a lighting assembly having a plurality of lighting devices arranged into a plurality of lighting groups, the light assembly having a predetermined maximum power, and a multiple-input power converter electrically coupled to the power source and the lighting assembly for powering the lighting assembly using the power source, and for charging the battery assembly using the solar panel. The multiple-input power converter is configured for calculating a power upper-bound based on the level of stored energy in the battery assembly and the length of a night time, and selecting at least a subset of the lighting groups and powering the selected lighting groups for illumination using the battery assembly for preventing exhausting the stored energy of the battery assembly before the battery assembly can be charged by the solar panel.
