For achieving the above object, the utility model adopts following technical scheme:
LED driver module circuit based on the CRD current regulator diode is characterized in that: comprise female straight cutting and curved female plug, and the branch road that is electrically connected on many parallel connections between described female straight cutting and the described curved female plug; Every constant current branch road that described branch road includes LED lamp pearl and connects with described LED lamp pearl wherein, many parallel with one another forming of branch road that are in series by CRD current regulator diode and resistance of route are propped up in described constant current.
The beneficial effects of the utility model are: this circuit can constant-current driving LED, and can many branch roads optionally in parallel, drives a plurality of LED simultaneously.
Description of drawings
Fig. 1 is the circuit diagram based on the LED driver module circuit of CRD current regulator diode of an embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, introduce preferred implementation of the present utility model in detail.Be illustrated in figure 1 as preferred embodiment of the present utility model.
Should comprise female straight cutting 10 and curved female plug 20 based on the LED driver module circuit of CRD current regulator diode, female straight cutting 10 has positive and negative polarities, and curved straight cutting 20 has 4 anode interface and 1 negative pole interface.Above-mentioned LED driver module circuit also comprises the branch road that is electrically connected on 2 parallel connections between female straight cutting 10 and the curved female plug 20.Every constant current branch road that branch road includes LED lamp pearl and connects with its LED lamp pearl, constant current prop up parallel with one another the forming of branch road that route CRD current regulator diode and resistance are in series.
Particularly, wherein article one is propped up route circuit b, c, d, i, a composition, and second props up route circuit b, e, f, g, h, a composition.Wherein, article one branch road comprises the constant current branch road of a LED lamp pearl 51 and series connection with it; This constant current is propped up following two the branch branch roads of route and is formed in parallel: the branch branch road that (1) is made up of CRD current regulator diode 43 (30MA) series resistance 33, the branch branch road that (2) are made up of CRD current regulator diode 44 (30MA) series resistance 34.The second branch road is similar to article one branch road, comprise LED lamp pearl 52 with and the series connection the constant current branch road; This constant current is propped up following two the branch branch roads of route and is formed in parallel: the branch branch road that (1) is made up of CRD current regulator diode 42 series resistances 31 (20MA), the branch branch road that (2) are made up of CRD current regulator diode 41 series resistances 32 (20MA).Certainly, in other embodiment of the utility model, can also several first above-mentioned branch road or second branch roads in parallel as required.
In the foregoing circuit, adopt each two of the current regulator diodes of 20MA, two kinds of specification electric currents of 30MA to constitute 4 tunnel constant currents output, allow suitably to increase way as fruit volume, current regulator diode is more than 20 in addition, 30MA, also having 10MA, 15MA, 40MA, mainly is to mate according to different small-power paster lamp pearls.
Above-mentioned constant current value all is the driving current value of paster lamp pearls commonly used such as general general 3528,3014 on the market, each road output current in the module can be controlled (continuous current of each current regulator diode is between 10-40MA, and 10,20,30,40 is regular size) by corresponding single current regulator diode.
As if wanting big current drives, then need in parallel use of the current regulator diode of same specification got final product, if want the electric current of 60MA, just can adopt the diode of 2 30MA to carry out the parallel connection use such as me.
Because input is the high direct voltage of volt more than 300; so input should prevent the both positive and negative polarity reversal connection in circuit; burn out circuit, each road of output circuit all adds an OR resistance (such as resistance 33,34,31,32) in case prevent that current regulator diode from burning out the back lamp pearl is played a protective effect.
In addition, the input of module adopts the straight busbar of 2P to insert, and output adopts the curved busbar of 5P to insert, and the wiring of giving up is in the past installed, and improves the process Installation mode.
Described above only is preferred embodiment of the present utility model, can not limit scope of the present utility model with this.For the equivalents and the replacement of technical solutions of the utility model, all in the utility model protection range.
