That's not a problem, Kish says: transistors can be a good source of noise when operated at low voltage, and we can already fit billions of them on a chip.
The LED fixture shall be operated at constant and carefully regulated current levels. LEDS shall not be overdriven beyond their specified nominal voltage and current.
LED灯具须在稳定的、精心调控的电流强度下运行，不应在超过其额定电压或额定电流的情况下超负荷运行。
