摘要:
A light-emitting diode is provided, which comprises a baseplate; at least one semiconductor light-emitting element installed on the baseplate; and at least one deformable lens conducting a light beam emitted by the semiconductor light-emitting element. The deformable lens not only has a varifocal function but also can deform into a convex, plane, concave or irregular lens, and thus can adjust the light beam emitted by the semiconductor light-emitting element to have different patterns and present different optical signals.

A brightness adjusting device for a light-emitting diode (LED) display panel has at least one photo sensor, a control circuit, a timing controller and a driving circuit. The LED display panel is composed of multiple LEDs being divided into groups according to color. The photo sensor sequentially senses brightness of the groups of LEDs and generates brightness values. The control circuit compares the brightness values to standard brightness values. Based on the compared results, the driving circuit adjusts the brightness of corresponding LEDs.
摘要:
An apparatus for controlling the growth of an organism includes a parameter control system, a remote control center, a control box, at least one environment-regulating device and at least one sensor. The parameter control system is stored with a plurality of operation modes, and environmental parameters that correspond to the respective operation modes and govern a variety of growth conditions for different species of organisms. The apparatus can automatically change the environmental conditions from one state to another, so as to meet the user's requirements and enhance the productivity without being limited by the ambient conditions.
