LED illumination equipment and Open-circuit breakover element thereof

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.

Description

technical field [0001] The invention belongs to electronic components and devices, and relates to an open circuit fault conduction element of LED lighting equipment and the LED illumination equipment including the open circuit conduction element. Background technique [0002] At present, because LED lighting has the advantages of low power consumption and long life, it is gradually becoming a trend to replace traditional lamps with LED lighting. However, due to the characteristics of LED devices, large-scale lamps such as LED lighting fixtures usually use a structure in which multiple LED tubes are connected in series in the circuit. LED lights in series with it. Therefore, such lamps are usually equipped with an open circuit protection circuit to ensure that the entire circuit can be kept on when an open circuit fault occurs in one LED tube. Most of the existing open-circuit protection circuits use Zener diodes and other devices, which consume high power consumption durin...
