The specific embodiment
A kind of LED lamp as shown in Figure 1, comprise working of plastics 1, last working of plastics 1 top is with the lamp holder 2 that connects power supply, last working of plastics 1 bottom connects working of plastics 3 down, shown in Fig. 1 (b), array has a plurality of LED light emitting diodes 31 in the following working of plastics, increase the quantity of LED light emitting diode, can increase the power of LED lamp, shown in Fig. 1 (a), in last working of plastics 1, also be provided with electronic control board 12, electronic control board 12 comprises circuit plate body and electronic control circuit, the duty of electronic control circuit control LED light emitting diode 31, last working of plastics and the following working of plastics shell two-piece structure for adopting fire retardant plastic material to make, volume is little, and is in light weight.
The theory diagram of the internal electron control circuit of LED lamp of the present invention as shown in Figure 2 is after main circuit is connected the 220V alternating current, through C
0Step-down, R
0Current limliting, bridge rectifier 4 rectifications and C
1Main circuit is divided into battery charge control circuit after converting alternating current to direct current after the filtering, and high light, low light level control circuit and three supply circuits of function control circuit also are provided with resistance R in main circuit
1, C
1* R
1Time constant, decision has a power failure the time expand that the back emergency light is opened.The terminal of described three supply circuits connects LED light emitting diode current stabilization circuit respectively, connect by LED light emitting diode current stabilization circuit again and control LED light emitting diode combined, described function control circuit connection and control battery charge control circuit and high light, low light level control circuit, described function control circuit is provided with light-sensitive device 13, light-sensitive device is photo resistance R, photo resistance R is arranged on working of plastics 1 housing and with function control circuit and links to each other, described battery charge control circuit also connects battery 5, change the capacity of battery 5, can prolong discharge time.Battery charger can be according to battery 5 capacity status, and charging stops behind the full charge to dash automatically automatically, make the interior battery 5 of LED lamp remain at full power state.After battery 5 discharges reached setting voltage value, function control circuit outputed signal to LED light emitting diode current stabilization circuit, it was stopped to the power supply of LED light emitting diode combined, battery 5 not overdischarge in the protection LED lamp.
As shown in Figure 3 for LED lamp of the present invention when general lighting to the control procedure of LED light emitting diode duty, when general lighting, open the 220V ac power switch, the LED lamp is luminous by above-mentioned electronic control circuit, when the LED lamp is in the high light state, if ambient light intensity is greater than LED lamp wiring intensity settings, the function control circuit of band photo resistance R signals to high light, low light level control circuit, and the LED lamp is transformed into low light level state from high light automatically; If ambient light intensity less than LED lamp wiring intensity settings, then needs manual-lock 220V alternating-current switch, opens the 220V alternating-current switch again, the LED lamp just can be transformed into low light level state.When after the LED lamp is luminous, being in low light level state, if ambient light intensity greater than LED lamp wiring intensity settings, the LED lamp still just keeps low light level state; If ambient light intensity less than LED lamp wiring intensity settings, then needs manual-lock 220V alternating-current switch, open the 220V alternating-current switch again, the LED lamp just can be transformed into the high light state.Whenever close or open once just 220V alternating-current switch, the LED circuit for lamp is luminance of conversion automatically, and is easy to use, and saves electric energy under the condition that does not influence use significantly, prolongs the service life of LED lamp.
