Accompanying drawing explanation
Fig. 1 is a kind of Novel LED illuminating schematic diagram of device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of Novel LED illuminating device, is characterized in that, comprises the LED drive circuit and LED array that connect successively, and described LED drive circuit comprises the input interface J1, rectification circuit, the control circuit that connect successively; Described LED array is rectanglar arrangement, and described rectification circuit comprises rectifier bridge chip U1, and described control circuit comprises main control chip U2.
Rectifier bridge chip U1 two input pin is connected with input interface J1 two input respectively; Described control circuit also comprises resistance R1, electric capacity C1; Rectifier bridge chip U1 output head anode is directly connected with the positive pole of LED array; No. 1 pin S1 of main control chip U2 is connected to No. 2 pins and rectifier bridge chip U1 negative pole of output end through resistance R1; No. 6 pin D1 of main control chip U2 are connected with LED array negative pole with one end of electric capacity C1 simultaneously; The other end of electric capacity C1 connects the negative pole of output end of rectifier bridge chip U1.
Rectifier bridge chip U1 adopts rectifier bridge chip MB8S, and described main control chip U2 adopts single-channel constant current LED control chip RM9003E.
LED array is four row eight rows, four row LED of LED array by two strings two and connect, namely, be divided into 4 row, often row 8, then two row series connection, last in parallel again, it is very few that this connected mode avoids series LED particle, the problem that when drive circuit output voltage is lower, efficiency is lower.
Described input interface is power input interface.
The main control chip U2 RM9003E that this lighting device adopts is that single channel LED flows over drived control chip, can Direct driver high-voltage LED lamp string, and output current is arranged by outer meeting resistance R1, and constant output current is in set point.Chip system structure is simple, and peripheral component is few, and circuit is simple.This lighting device achieves the Current adjustment function of constant current, for LED array provides stabling current; Whole circuit only needs 4 elements, reliable and stable, cost-saving; Simultaneously without the need to electrochemical capacitor, magnetic element, save space greatly, make circuit can miniaturized, flattening, be applicable to being applied to occasion volume or shape being had to particular requirement.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
