The utility model content
The purpose of this utility model provides a kind of high-power suction top lighting lamp circuit device that a kind of efficient is high, cost is low, easy for installation.
The purpose of this utility model is to realize like this, a kind of high-power suction top lighting lamp circuit device, it is characterized in that: comprise rectification circuit and led drive circuit, led drive circuit is the constant current linear drive circuit, the rectification circuit positive output end is divided into two-way, connect first via constant current linear drive circuit anode after the anode of one tunnel LED that is connected in series with the first via is electrically connected, first via constant current linear drive circuit negative terminal is electrically connected with the negative terminal of rectification circuit; Connect the second tunnel constant current linear drive circuit anode after the anode of the LED that another road and the second tunnel is connected in series is electrically connected, the second tunnel constant current linear drive circuit negative terminal is electrically connected with the negative terminal of rectification circuit.
The described LED that is connected in series is distributed on the lamp plate or on a plurality of lamp plate.
Every a string 90-125 of the having LED of the described LED that is connected in series.
The utility model has the advantages that: owing to adopting a plurality of constant current linear drive circuits and No. one rectification circuit, drive simultaneously the above LED that is connected in series of two-way or two-way, every a string LED at 90-150 has only improved light efficiency and cost greatly, improved simultaneously light efficiency, made light efficiency more than 90%.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the utility model embodiment circuit theory diagrams.
Among the figure, 1, AC power; 2, rectification circuit; 3, constant current linear drive circuit; 4, the LED that is connected in series.
Embodiment
As shown in Figure 1, comprise rectification circuit 2 and led drive circuit, led drive circuit is constant current linear drive circuit 3, rectification circuit 2 positive output ends are divided into two-way, connect first via constant current linear drive circuit 3 anodes after the anode of one tunnel LED4 that is connected in series with the first via is electrically connected, first via constant current linear drive circuit 3 negative terminals are electrically connected with the negative terminal of rectification circuit 2; Connect the second tunnel constant current linear drive circuit 3 anodes after the anode of the LED4 that another road and the second tunnel is connected in series is electrically connected, the second tunnel constant current linear drive circuit 3 negative terminals are electrically connected with the negative terminal of rectification circuit 2.
During work, AC power 1 is electrically connected with the ac input end of rectification circuit 2, by rectification circuit 2 220V or 110V AC rectification are become direct current, behind filter capacitor, rectification circuit 2 positive output ends split into two-way, enter first via constant current linear drive circuit 3 inputs behind the LED4 that the first via of leading up to is connected in series, the LED4 that 3 pairs of first via of first via constant current linear drive circuit are connected in series carries out linearity adjustment, makes on its constant-current circuit that is operated in setting.The input that another road enters the second tunnel constant current linear drive circuit 3 after by the second tunnel LED4 that is connected in series is carried on the constant current linear drive circuit 3,3 couples the second tunnel LED4 that are connected in series of the second tunnel constant current linear drive circuit carry out linearity adjustment, make on its constant-current circuit that is operated in setting.
Because rectification circuit 2 can be operated on the larger electric current, such as 1-2A, therefore, can connect LED and the constant current linear drive circuit that multiple series series connects behind the rectification circuit 2, can form like this led drive circuit of hectowatt.
The LED4 that is connected in series is distributed on the lamp plate or on a plurality of lamp plate.Every a string 90-125 of the having LED of the LED4 that is connected in series.The voltage of AC power 1 adopts 220V or 110V, and is also relevant with the wavelength of LED, and red LED tube voltage drop is at 2V, other look between 2.2-3.2V.
The parts that the present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not one by one narration.
