Description
[technical field]
The present invention relates to a kind of light-emitting diode, or rather, relate to a kind of light-emitting diode with breaking protection circuit.
[background technology]
Light-emitting diode compare with the energy-saving lighting lamp of general photo-voltaic power supply adapted have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage.Along with led technology, especially the large-power light-emitting diodes technology is full-fledged, and light-emitting diode has begun to be widely used in lighting field, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.
In order to satisfy the demand of people's brightness of illumination, the lighting device that with the light-emitting diode is light source now all comprises a lot of light-emitting diodes usually, and these light-emitting diodes generally form an illuminating module with the form of many series connection earlier, then with these illuminating module common integrated light source that forms light emitting diode illuminating apparatus in parallel.Yet, there is following defective in this design: when a light-emitting diode in a certain illuminating module damages disconnection, cause the light-emitting diode of whole illuminating module do not have electric current by and can not work on, caused the waste of this illuminating module so on the one hand, also influence the illuminating effect of whole light emitting diode illuminating apparatus on the other hand to a greater extent, reduced the reliability of light emitting diode illuminating apparatus.
Therefore, people demand the appearance of a kind of new light-emitting diode of demand urgently, and this light-emitting diode can solve the above problems.
[summary of the invention]
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of light-emitting diode with breaking protection circuit is provided.
The present invention is achieved by the following technical solutions: a kind of light-emitting diode, comprise support and light-emitting diode chip for backlight unit, also comprise a breaking protection circuit, this breaking protection circuit is in parallel with described light-emitting diode chip for backlight unit, described breaking protection circuit comprises a current-limiting resistance, two divider resistances and a voltage-stabilizing device, and an end of wherein said current-limiting resistance is connected with the positive pole of voltage-stabilizing device and an end of divider resistance respectively; The other end of divider resistance is connected with the reference utmost point of voltage-stabilizing device and an end of another divider resistance respectively; The other end of described another divider resistance is connected with the negative pole of voltage-stabilizing device.
Described breaking protection circuit is an integrated circuit, is fixed on the described support.
Described support comprises first support and second support, and described integrated circuit is fixed on first support or second support.
Described voltage-stabilizing device is one 431 electronic devices.
Compared with prior art; light-emitting diode provided by the invention; by a breaking protection circuit in parallel with light-emitting diode chip for backlight unit is set; make when the circuit in parallel with breaking protection circuit disconnects; this breaking protection circuit is kept the conducting of light-emitting diode, has improved the reliability of the lighting device that uses this light-emitting diode.
