The positive and negative wire inlet ends of each LED lamp strip VL (or VLN) are respectively connected with an upper round metal sheet JC (or JCN) which is bonded on the lower outer part of the front end of the shell through a lead; each LED lamp strip VL (or VLN) is matched with a relay K1 (or K1N) arranged in the shell, the anode of the last LED lamp strip VL2 (or VL2N) connected in series of each LED lamp strip VL (or VLN) and the cathode incoming line end of each LED lamp strip 4 are respectively connected with the anode and the cathode of the relay K1 (or K1N) through leads, the control power input end of the relay K1 (or K1N) of each LED lamp strip VL (or VLN) is connected with the cathode incoming line end of each LED lamp strip VL (or VLN) through leads, and the normally closed contact end of the relay K1 (or K1N) is LED out of the rear end of the shell through a lead; two sides of the inner end of each groove are respectively adhered with a circular plastic sheet by glue, and a lower circular metal sheet JD (or JDN) is adhered to each plastic sheet; each LED lamp strip VL (or VLN) is attracted in each groove through a magnet, and the two upper metal JC (or JCN) and the two lower metal JD (or JDN) are respectively contacted and are electrically communicated.

As shown in fig. 1, 2 and 3, pins 1 and 2 of a power input end of a regulated power supply U1 and two poles of an alternating current 220V power supply are respectively connected through leads, two ends 3 and 4 of the power output of the stabilized voltage power supply U1, two ends 1 and 2 of the power input of the short message module U3, the other end of the photoresistor RL at two ends of the power input of the light control circuit and an emitting electrode of the NPN triode Q1 are respectively connected through leads, two ends 3 and 4 of the time control switch U2 and two lower metal sheets JD (or JDN) of four grooves at two ends of the power output of the light control circuit are respectively connected through leads, a trigger signal input end 3 of the short message module U3 is connected with four leads, the four leads are respectively LED out from openings in the four grooves to the outer ends of the grooves (the openings and the leads are sealed by glue), and a normally closed contact end of a relay K1 (or K1N) of four LED lamp beads and a trigger signal input end 3 pins (four leads) of the short.

As shown in fig. 1, 2 and 3, other using methods and processes of the novel multimedia information machine body are completely the same as those of the existing multimedia information machine, and are not described herein again. This is novel, four LED lamp strip VL (or VLN) are respectively through 45 actuation modes of magnet, install in the outer end recess of multimedia information machine body (magnet 45 and multimedia information machine 1's steel material actuation are in the same place), and keep level with multimedia information machine body 1's shell surface, the pleasing to the eye compactness of appearance, and divide into four, can conveniently not open LED lamp strip VL (or VLN) of carrying out the damage under the shell prerequisite of multimedia information machine body and change, can improve maintenance speed, and one of them LED lamp strip damages the back, do not need whole LED lamp strips of changing, can save the cost for the user. After the 220V ac power supply enters pins 1 and 2 of the regulated power supply U1, the regulated power supply U1 outputs a stable 24V dc power supply under the action of its internal circuit at pins 3 and 4, and enters the two ends of the power input of the light control circuit and short message module U3, so that the light control circuit and short message module U3 is in a power-on working state. After the light control circuit is powered on, the photoresistor RL has high illumination intensity and low resistance value of about 100K in the daytime, at the moment, a power supply output by the positive electrode of the stabilized voltage power supply U1 is subjected to voltage reduction and current limitation by the photoresistor RL, then the base voltage of the power supply which enters the NPN triode Q1 is higher than 0.7V, then the NPN triode Q1 is conducted with a collector to output low level to enter the negative power supply input end of the relay K, and the relay K is powered on to attract the control power supply input end and the normally closed contact end to be open. Because the positive power supply input end of the time control switch U2 is connected with the normally closed contact end of the relay K, the time control switch U2 cannot be powered to work at the moment, and then four LED lamp beads VL (or VLN) at the rear stage cannot be powered to emit light, so that the purposes of automatic control and energy saving are achieved. At night, the light intensity of the photosensitive resistor RL is small, the resistance value of the photosensitive resistor RL is higher than about 10M, at the moment, a power supply output by the positive electrode of the stabilized voltage supply U1 is subjected to voltage reduction and current limitation by the photosensitive resistor RL, the base voltage of the power supply entering the NPN triode Q1 is lower than 0.7V, then, the NPN triode Q1 stops a collector electrode and does not output low level to enter the negative power supply input end of the relay K, and the relay K is not electrified and does not attract the control power supply input end and the normally closed. Because the pin 1 of the positive power supply input end of the time control switch U2 is connected with the normally closed contact end of the relay K, the time control switch U2 is electrified to work at night every day.

As shown in fig. 1, 2, and 3, at night every day, after the time switch U2 is powered on, under the action of its internal circuit and the power supply output time of 3 and 4 pins set by a technician, the 3 and 4 pins of the time switch U2 will output power supply for 3 seconds (which can be set as required) every 5 seconds, and enter four groups of lower metal pieces JD (or JDN), and enter two ends of the power supply input of four LED light bars vl (vln) through four groups of upper metal pieces JC (or JCN), so that the four LED light bars vl (vln) will operate in a mode of powering on and lighting for 5 seconds every 3 seconds, thereby achieving the effects of decoration and illumination. In four LED lamp strips VL (VLN) and SMS module U3, when every LED lamp strip VL (VLN) normally works, namely eight LED lamp pearls are effectively connected in series, the positive pole of the 24V power supply enters the positive pole of the last LED lamp pearl VL2 (or VL2N) and the positive pole power supply input end of relay K1 after being stepped down by the eight LED lamp pearls connected in series, and the relay K1 is electrified to attract the control power supply input end and the normally closed contact end to be opened. Because the control power supply input end of the relay K1 (or K1N) is connected with the negative wire inlet end of each LED lamp strip, and the pin 3 of the trigger signal input end of the short message module U3 is connected with the normally closed contact end of the relay K1 (or LK1N) of the four LED lamp beads, the short message module U3 cannot send short messages at the moment. In four LED lamp strips VL (VLN) and SMS module U3, when arbitrary LED lamp strip VL (VLN) abnormal work, namely eight LED lamp pearls of it establish ties inefficiently (one LED lamp pearl damages and all can lead to establishing ties and become invalid), 24V power supply positive pole gets into the anodal (about 3V of voltage here) and relay K1 positive power input end of last LED lamp pearl VL2 (or VL2N) after eight LED lamp pearls that establish ties step down no longer, relay K1 loses the electricity and no longer attracts its control power input end and normally closed contact end closed. Because the control power supply input end of the relay K1 (or K1N) is connected with the negative pole incoming line end of each LED lamp strip, the 3 pins of the trigger signal input end of the short message module U3 are connected with the normally closed contact end of the relay K1 (or LK1N) of the four LED lamp beads, at the moment, the 3 pins of the short message module U3 can be input with low level signals, and the short message module U3 can automatically push a short message for the mobile phone of a manager under the action of the internal circuit of the short message module U3. It should be noted that, within 3 seconds of the time when the 3-pin of the time control switch U2 stops outputting the power, since the relay K1 (or K1N) controls the power input end to lose power, the short message module U3 does not send a short message. This is novel when night, can work under light-operated circuit control automatically, plays and decorates and the illumination effect, has beautified the municipal environment, and can in time change through the SMS suggestion managers by the very first time when having LED lamp strip to damage, has guaranteed the normal work of all LED lamp strips. The photoresistor RL model is MD 45; the model of the NPN triode Q1 is 9013; the relays K, K1 (or K1N) are DC24V, DC3V relays, respectively.
