Description
Technical field
The utility model relates to a kind of ceiling light, particularly a kind of cheaply high-power suction top lighting lamp circuit device.
Background technology
Existing ceiling light mostly is the daylight cylinder structure usually, comprises that base, fluorescent tube, lampshade three parts consist of, and lampshade will absorb a part of light, but can have, and does not have lampshade to affect attractive in appearance.
The ceiling light that the LED lamp consists of then because drive circuit adopts the capacitance resistance partial pressure type, greatly reduces light efficiency, has affected greatly the high efficiency characteristics of LED lamp.
Large tracts of land area source or line source illuminating lamp also are embodied in the fluorescent tube illuminating lamp, fluorescent tube illuminating lamp and ceiling light also have the employing Switching Power Supply, when adopting Switching Power Supply LED exist simultaneously with series and parallel connections, because each road load capacity is different, make Switching Power Supply cannot adjust to optimum state, the one, affect constant current, the 2nd, reduce light efficiency.
The utility model content
The purpose of this utility model provides that a kind of efficient is high, cost is low, easy for installation a kind of cheaply high-power suction top lighting lamp circuit device.
The purpose of this utility model is to realize like this, a kind of cheaply 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, the anode of one tunnel LED that is connected in series with the first via is electrically connected, the anode of the LED that another road and the second tunnel is connected in series is electrically connected, the LED that the first via is connected in series connects constant current linear drive circuit anode with being connected after LED negative terminal that the road is connected in series connects, and 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.
The described LED that is connected in series has 90-125 only.
The voltage of described AC power adopts 220V or 110V.
The utility model has the advantages that: owing to adopting a constant current linear drive circuit and No. one rectification circuit, drive simultaneously the LED that two-way is connected in series, 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, the anode of one tunnel LED4 that is connected in series with the first via is electrically connected, the anode of the LED4 that another road and the second tunnel is connected in series is electrically connected, and the LED4 that the first via is connected in series connects constant current linear drive circuit 3 anodes with being connected after LED4 negative terminal that the road is connected in series connects, and constant current linear drive circuit 3 negative terminals are electrically connected with the negative terminal of rectification circuit 2.
During work, AC power 1 becomes direct current through rectification circuit 2 with 220V or 110V AC rectification, behind filter capacitor, rectification circuit 2 positive output ends split into two-way, enter constant-current contour drive circuit 3 inputs behind the LED4 that the first via of leading up to is connected in series, after confluxing, the same input that another road enters constant-current contour drive circuit 3 after by the second tunnel LED4 that is connected in series is carried on the constant current linear drive circuit 3, the LED4 that 3 pairs of two-way of 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 LED4 that is connected in series is distributed on the lamp plate or on a plurality of lamp plate.The LED4 that is connected in series has 90-125 only, and 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.
