[technical field]
The utility model relates to a kind of light-emitting diode, or rather, relates 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.
[utility model content]
Technical problem to be solved in the utility model 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 utility model is achieved through 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; the light-emitting diode that the utility model provides; 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.
[description of drawings]
Fig. 1 is the utility model light-emitting diode structure schematic diagram.
Fig. 2 is the vertical view of the utility model light-emitting diode.
Fig. 3 is the circuit diagram of the utility model light-emitting diode.
[embodiment]
See also Fig. 1 and shown in Figure 3, the light-emitting diode 5 that the utility model disclosed comprises first support 51, second support 52, light-emitting diode chip for backlight unit 53 and breaking protection circuit 54.Described light-emitting diode chip for backlight unit 53 is contained in the reverberation bowl of first support 51.Described breaking protection circuit 54 is packaged into an integrated circuit 55, and described integrated circuit 55 is fixed in above the top end face 520 of second support 52.Certainly, integrated circuit 55 also can be fixed in above first support 51.
See also shown in Figure 2ly, integrated circuit 55 1 utmost points are connected with first support 51, and another utmost point is connected with second support 52, forms in parallel with light-emitting diode chip for backlight unit 53.Described breaking protection circuit 54 comprises current-limiting resistance R1, divider resistance R2, R3 and voltage-stabilizing device M (adopting 431 electronic devices in the present embodiment), and an end of resistance R 1 is connected with the anodal A of voltage-stabilizing device M and the end of divider resistance R2 respectively; The other end of divider resistance R2 is connected with the reference utmost point REF of voltage-stabilizing device M and the end of divider resistance R3 respectively; The negative pole K of the other end of divider resistance R3 and voltage-stabilizing device M is connected.
When the circuit in parallel with breaking protection circuit 54 56 disconnected, light-emitting diode chip for backlight unit 53 no longer includes electric current to be passed through.Breaking protection circuit 54 holding circuit conductings.The output voltage of voltage-stabilizing device M is only relevant with divider resistance R2, R3, and the output voltage that light-emitting diode 5 disconnects back voltage-stabilizing device M remains unchanged, and light-emitting diode chip for backlight unit 53 both end voltage are also constant.In the present embodiment, the resistance of divider resistance R2, R3 is preferably very big, and the electric current by divider resistance R2, R3 is several microamperes, can ignore.The electric current that passes through before electric current by voltage-stabilizing device M and light-emitting diode 5 disconnect changes little.
The light-emitting diode 5 that the utility model provides; by a breaking protection circuit 54 in parallel with light-emitting diode chip for backlight unit 53 is set; make when circuit 56 disconnections in parallel with breaking protection circuit 54; this breaking protection circuit 54 is kept the conducting of light-emitting diode 5, has improved the reliability of the lighting device that uses this light-emitting diode.
More than describing is embodiment of the present utility model only, forgives and can understand, and under the prerequisite that does not depart from the utility model design, all should be included within the technical conceive of the present utility model simple modification of the present utility model and replacement.
