Abstract

The invention relates to a lighting device, comprising a lighting circuit unit and an open resistant circuit unit, wherein the lighting circuit unit is driven by a first drive voltage, the open resistant circuit unit is parallel connected with the lighting circuit unit and driven by a second drive voltage higher than the first drive voltage. The invention parallel connects the open resistant circuit unit and a light emitting diode, to avoid the lighting devices in closed circuit to fail to light, when one light emitting diode of a plurality of serially connected lighting device is fail to light by open circuit, and avoid open circuit caused by damaged one light emitting diode, with practicality.

Description

technical field [0001] The invention relates to a light-emitting device, in particular to a light-emitting device with a light-emitting diode, which can avoid the open circuit phenomenon caused by the damage of a single light-emitting diode. Background technique [0002] Light emitting diodes have a wide range of applications. In addition to being used as general lighting, light emitting diodes have recently been used as light sources in backlight modules of display devices. As far as the backlight modules of displays are concerned, they can generally be divided into two categories: direct-type backlight modules and edge-type backlight modules. A plurality of light-emitting devices (light-emitting modules) are used in the direct-type backlight module, while one light-emitting device is mostly used in the side-light type backlight module. What needs to be specially explained here is that as the size of the display is different and the light-emitting mode of the backlight mod...
