LED模块在标准上的定义是一种组合式照明光源装置..不包括控制装置.,作者: oahemr 时间: 2012-1-27 18:20
其实标准中关于定义已经讲得很清楚，估计很多朋友看标准时不重视定义的理解。作者: 59779520 时间: 2012-1-27 18:20
UL 8750:
3.10 LED (LIGHT EMITTING DIODE) – A solid-state component embodying a p-n junction, emitting
optical radiation when excited by an electric current.
3.11 LED ARRAY (LED MODULE) – An assembly of one or more LED discrete electronic components
on a printed circuit board, typically with optics and additional thermal, mechanical, and electrical
interfaces.
3.12 LED CONTROL MODULE (LED CONTROLLER) – Electronic circuitry interposed between the
power source and an LED array to dim, switch, or otherwise control the electrical energy to the LED
array. The device does not contain a power source and is not connected directly to the branch circuit.
3.13 LED DRIVER – A power source that adjusts the voltage or current to LEDs, ranging in complexity
from a resistor to a constant voltage or constant current power supply. Also referred to as Lamp Control
Gear. (See also Power Source.)
3.14 LED PACKAGE – An assembly of one or more LED die that contains wire bond connections and
may include an optical element and thermal, mechanical, and electrical interfaces. The package does
not include a power source and is not connected directly to the branch circuit.作者: MS168 时间: 2012-1-28 12:05
