Description

The board-like LED bulb of monolithic integrated circuit

Technical field

The utility model refers to the board-like LED bulb of a kind of monolithic integrated circuit, the technical field that relates to a kind of bulb being formed by one chip circuit board and lamp holder, and have to reduce costs and save assembling manpower and man-hour, reduce follow-up artificial welding, relatively can reduce defective products rate and Improving The Quality of Products.

Background technology

Press, prior art LED bulb used is (as Fig. 1, shown in Fig. 2) consider optical considerations, the light source of its LED6 must be upward, so LED6 is located at first circuit board 81 tops that a level is put, another second circuit board 82 vertical direction is put and is located in lamp holder 7, its main cause is for example bridge rectifier 91 of associated electrical part, AC step-down high-voltage capacitance 92, resistance 93, LED current-limiting resistance 94 can occupy certain space, so each electronic building brick cannot be arranged at same first circuit board 81 tops with LED6, because the aforementioned LED of commonly using bulb need to arrange first and second two circuit boards 81, 82, therefore do not increase cost, follow-up artificial welding is also many, relatively also can increase defective products rate.
