摘要:
The present disclosure relates to a programmable underwater lighting system for pools and spas. A plurality of underwater lights, each having a plurality of LEDs for producing light of various colors, a microprocessor for controlling the plurality of LEDs, and a memory in communication with the microprocessor containing one or more stored control programs, allow for the generation of various lighting effects in a pool or spa. A central controller is provided in communication with the plurality of underwater lights, and allows a user to define or select a desired lighting effect (such as a sequence, a fading effect, a “moving” color pattern, etc.) using a display and a keyboard. Optionally, a handheld remote control could be provided, in wireless communication with the central controller, for allowing a user to remotely control the plurality of lighting fixtures. When a desired lighting effect is defined by a user, the central controller transmits an instruction to each of the plurality of underwater lights instructing each light to execute a specific stored control program in its memory to produce the desired lighting effect. Each of the lights could be in communication with the central controller using a power line and an associated power line carrier data protocol, and each light could be provided with a thermal management system for monitoring the operating temperature of the light and automatically adjusting the brightness of the light to prevent dangerous temperatures.
摘要:
A lamp tube (100) and an end cap structure (101) thereof are provided. The end cap structure (101) includes a first cover (110), a rotatable body (120), at least one electrode pin (130) and a circuit board (150). The rotatable body (120) is disposed on the first cover (110). The at least one electrode pin (130) is disposed on the first cover (110) for receiving an external power (200). The circuit board (150) is disposed within the first cover (110). The circuit board (150) has at least one contact point (151). The at least one contact point (151) and the at least one electrode pin (130) are electrically connected or insulated via the rotation of the rotatable body (120).
摘要:
An emergency lighting module for providing emergency power to a solid state luminaire. The emergency lighting module includes a first input configured to receive a DC input voltage from the solid state luminaire, a second input configured to receive a status signal indicative of the status of an AC line voltage, and a first output configured to supply a DC output voltage to the solid state luminaire. The emergency lighting module is configured to supply the DC output voltage to the solid state luminaire in response to a reduction of the AC line voltage.
