The specific embodiment

As Fig. 1, shown in Figure 5, it comprises lamp holder 1 and the housing 2 that is connected with lamp holder 1 the utility model, is provided with LED lamp 3 on housing 2, in the periphery of LED lamp 3 lampshade 4 is set, and lampshade 4 is connected with housing 2.Lighting circuit and plasma generation circuit are set on the wiring board of housing 2, and above-mentioned lighting circuit and plasma generation circuit are connected in parallel.Use for convenient, series connection is provided with light switch K2 in lighting circuit; Series connection is provided with gauge tap K1 in plasma generation circuit.In the utility model, lamp casing is streamlined column, also can be square body or the like.

As shown in Figure 2, specifically, behind the rectification circuit of 220V alternating current through four diode D2 formations, become Rectified alternating current, this direct current can make light emitting diode D1 luminous, and the LED lighting circuit is started working.Simultaneously, in each half period of power supply, charge to capacitor C 1 by potentiometer WR1 and resistance R 2, when capacitor C 1 two ends charging voltage reaches turning back during voltage of bidirectional trigger diode BD3, this bidirectional trigger diode BD3 conducting, capacitor C 1 forms the gate pole that spike is added to IGCT RS1 to resistance R 1 discharge at the two ends of resistance R 1, make IGCT RS1 open-minded, light emitting diode D1 electrified light emitting; Meanwhile, to ozone generation circuit supply, make ozone generation circuit operate as normal generate ozone by transformer E1.Need to prove that the primary coil T1 of transformer E1 is linear diameter 0.8 * 18 circle, secondary coil T2 is linear diameter 0.1 * 1800 circle.In addition, after IGCT RS1 opened, its anode-cathode voltage was reduced to about 1V.When the alternating current zero passage, IGCT RS1 treats following one-period, and capacitor C 1 is charged again, repeats said process.So regulator potentiometer WR1 can change the capacitor C speed in 1 charging interval, thereby can control the mean value that light emitting diode D1 goes up voltage, make adjustable brightness, thereby constitute light adjusting circuit.
