Abstract
The invention relates to an open-circuit failure breakover element of LED illumination equipment and LED illumination equipment comprising the open-circuit breakover element, belonging to electronic components. According to the first technical scheme, the open-circuit breakover element of the LED illumination equipment comprises a silicon-controlled rectifier and a voltage regulator tube which are encapsulated in the same shell; the positive electrode of the silicon-controlled rectifier is the positive electrode of the whole element; the negative electrode of the silicon-controlled rectifier is the negative electrode of the whole element; the control electrode of the silicon-controlled rectifier is connected with the positive electrode of the voltage regulator tube; and the negative electrode of the pressure regulator tube is connected with the positive electrode of the silicon-controlled rectifier. The open-circuit breakover element and the LED illumination equipment comprising the element can maintain the breakover of an LED series circuit when a single LED has an open-circuit failure. Therefore, the normal light emitting of other LEDs is not influenced. As a loop is switched into conduction by using the silicon-controlled rectifier during the open-circuit protection, the voltage decrease is low, and the power consumption of the open-circuit protecting element is decreased.
