Abstract

The invention relates to a LED lighting device which comprises a shell and a plurality of LEDs, wherein a plurality of series of light-emitting module groups are formed by the LEDs, both ends of each LED in the light-emitting module are connected to a breaking protective circuit (3) in parallel, the breaking protective circuit (3) comprises a current-limiting resistance (R2), two divider resistances (R3, R4) and a voltage regulator chip (IC), one end of the current-limiting resistance (R2) is respectively connected to the anode (A) of the voltage regulator chip (IC) and one end of the dividerresistance (R3), the other end of the divider resistance (R3) is respectively connected to the reference pole (REF) of the voltage regulator chip (IC) and one end of the other divider resistance (4),the other end of the other divider resistance (R4) is connected to the cathode (K) of the voltage regulator chip (IC).

Description

【Technical field】 [0001] The present invention relates to an LED lighting device, more precisely, relates to an LED lighting device with an open circuit protection circuit. 【Background technique】 [0002] Compared with the energy-saving lighting fixtures used by general photovoltaic power sources, LED has the outstanding advantages of long life, low heat generation, not easy to be damaged, low power consumption and more energy saving. With the development and maturity of LED technology, especially high-power LED technology, LED has begun to be widely used in the lighting field, and people call it the fourth-generation lighting source that replaces fluorescent lamps and incandescent lamps in the 21st century. [0003] In order to meet people's demand for lighting brightness, current lighting devices that use LEDs as light sources usually contain many LEDs, and these LEDs are generally connected in series to form a light-emitting module, and then these light-emitting modules a...
