[0003] 2. Description of Related Art [0004] A large amount of electric energy is consumed every day by lamps used in large buildings, offices, parking lots, warehouses and the like. At present, many existing lamp light management systems employ a central control mechanism, and utilize the method of selecting the groups of the lighting devices in a wired connection mode or through using ZigBee wireless communication devices and then setting the dimming level of the individual lighting device groups. Meanwhile, a human pyroelectric infrared sensor or a microwave sensor for detecting the movement of human bodies or objects can also be additionally arranged on a single lamp to control the lighting device. The above design and modes have the following disadvantages: [0005] First, the central control mode and the wired mode need large investments in equipment in early stage and cause large work amounts. [0006] Second, maintaining a fixed brightness in a holding time in the control mode where the human pyroelectric infrared sensor is used wastes lots of electric energy in many cases. [0007] Third, the detecting range of the sensor is limited, and even if a person or an object moves in the detecting range of the sensor but the movement range fails to reach the detecting threshold of the sensor, the lighting device will turn off and suddenly plunge the occupant into darkness, resulting in poor use effect.; [0008] Fourth, use of a lighting control system in the wired or wireless mode requires setting IDs to the lighting devices, and only after the lighting devices are grouped can initial settings of parameters such as diming level and holding time be carried out, resulting in many resources put in manual commissioning and testing the an early stage, and large waste. [0009] Therefore, a fully-automatic lighting control system with low cost and without central control is urgently needed on the market BRIEF SUMMARY OF THE INVENTION [0010] The technical aim of the utility model is to provide a fully-automatic wireless lighting control system to overcome defects in the prior art.

All the plurality of lighting control units can communicate with each other through respective infrared transceiver modules to form a plurality of lighting control unit groups centered on any one of the lighting control units, the lighting control unit located at the circle center further sends lighting level signals to the plurality of lighting control unit groups through the infrared transceiver modules. The lighting control units in each lighting control unit group receive the lighting level signals and set the corresponding lighting levels matched with the lighting level signals. When the micro-controller of one lighting control unit receives ambient light detected by the lighting sensor and/or the occupancy detected by the human body detecting sensor, the micro-controller controls breakover of the optical coupler and work of the dimming driver so that the lighting device lights up with matched illuminance. [0012] As an explanation to the above technical scheme, in the technical scheme, the lighting control unit further comprises a status display component; the status display component is electrically connected with the micro-controller and the AC-DC power conversion unit; and the status display component displays in a mode matched with the network setting status of the lighting control unit circle. [0013] In the above technical scheme, the status display component is an LED or a liquid crystal display screen. [0014] In the above technical scheme, the lighting control unit located at the circle center can send the lighting level signals to the first lighting control unit group close to the circle center. The lighting control units in the first lighting control unit group receive the lighting level signals, andthe corresponding micro-controllers set the matched lighting levels and send lighting level signals to the second lighting control unit group close to the first lighting control unit group A plurality of circles of lighting control units send the lighting level signals in outwards sequence, and nine lighting control unit groups are configured with the e lighting levels gradually reducing from the circle center to the outside.

DETAILED DESCRIPTION OF THE INVENTION [0025] The utility model is further explained in detail with reference to Figures 1-4. [0026] Refer to Fig. 1-4. A fully-automatic infrared wireless lighting control system comprises a plurality of lighting control units; each of the plurality of lighting control units comprises a lighting sensor 9, an infrared transceiver module 10, a human body detecting module 8 which are electrically connected with a micro-controller 1 and an AC-DC power conversion unit 2; the micro-controller 1 is electrically connected with the AC-DC power conversion unit 2; and the lighting sensor 9 calculates the ambient light in the space. The AC-DC power conversion unit 2 is further electrically connected with an optical coupler 6, a dimming driver 5 and a direct current power output unit 7, and the AC-DC power conversion unit 2 is externally connected with an alternating current power source 3. The optical coupler 6 is further electrically connected with the dimming driver 5, and the dimming driver 5 is electrically connected with a lighting device 4. The lighting control unit is further electrically connected with a status display component 11 composed of an LED or a liquid crystal display screen, and the status display component 11 is electrically connected with the micro-controller 1 and the AC-DC power conversion unit 2. An AC-DC power source converts the external mains supply or alternating current into a direct current power source for working of the weak current parts such as the lighting sensor 9, the infrared transceiver module 10 and the human body detecting sensor 8, while the direct current power output unit 7 is a practical power source matched with the dimming driver 5. The plurality of lighting control units can communicate with each other through respective infrared transceiver modules 10 to form a plurality of lighting control unit groups centered on any one of the lighting control units, and the lighting control unit located in the circle center further sends lighting level signals to the plurality of lighting control unit groups through the infrared transceiver modules l0while the lighting control units in each lighting control unit group receive the lighting level signals and set the corresponding lighting levels matched with the lighting level signals. The status display component 11 displays in a mode matched with the network setting status of the lighting control unit circle. After networking is completed, when the micro-controller 1 of one lighting control unit receives ambient light detected by the lighting sensor 9 and/or occupancy detected by the human body detecting sensor 8, the micro-controller 1 controls breakover of the optical coupler 6 and work of the dimming driver 5, so the lighting device 4 lights up with the matched illuminance. Meanwhile, new network namely new lighting control unit groups, are formed, and the newly formed lighting control unit group will light up by the same matched illuminace in a gradient way. What should be explained is that the lighting control system can sense the movement of human bodies or objects according to a certain lighting control unit, and then generate a lighting control unit groups centered on the lighting control unit. In other words, a trigger source for triggering the lighting control unit varies with the position to make the corresponding lighting level of the lighting control unit change as well.. Moreover, the micro-controller 1 judges whether dimming is needed according to a measurement value of the ambient light collected by the lighting sensor 9, and when necessary, sends signals according to the required amount such that dimming driver can perform dimming , namely adjusting the lighting under the original lighting conditions.

[0027] The lighting control unit located at the circle center can send the lighting level signals to the first lighting control unit circle close to the circle center; the lighting control units in the first lighting control unit group receive the lighting level signals, and the corresponding micro-controllers 1 set the matched lighting levels and send the lighting level signals to the second lighting control unit group close to the first lighting control unit group. The plurality of lighting control unit groups send out the lighting level signals in sequence. There are nine lighting control unit groups, numbered from 1 to 9 in sequence, while the lighting control units are numbered as 2-10. The lighting levels decrease gradually from the circle center to the outside. The dimming driver 5 is a 0-10V dimming driver 5.. The optical coupler 6 is a three-end bidirectional silicon controlled coupler, and preferably, the three-end bidirectional silicon controlled coupler is a T1635-800 type three-end bidirectional silicon controlled coupler. The human body detecting sensor 8 is a human pyroelectric infrared sensor or a microwave sensor or an infrared sensor. The infrared transceiver module 10 is further connected with a wireless remote controller or a cell phone. The lighting control units are initially set through the wireless remote controller or the cell phone. [0028] The lighting control system has an application range. In order to ensure lighting where the lighting control system is used, the lighting control system permits a user to set the dimming maintaining status where the lighting is 10% 50% of the normal value by using the remote controller or the cell phone under the condition of maintaining a certain lighting all day, and also set the holding time of 100% lighting. Regarding parameter setting of the lighting device 4, the Broadcast function is adopted in the lighting control system. It is only required to set the parameters, including the number of the infrared broadcast lighting control unit groups, the corresponding dimming level and holding of lighting, in one lighting control unit, then automatically broadcast the set parameters to all the lighting control units in the same space (namely the same lighting control unit group) through the infrared transceiver module 10, and save the set parameters. [0029] The operation principle of the lighting control system is explained with examples below: [0030] Refer to Fig. 2-4, the human pyroelectric infrared sensor or the microwave sensor part or the infrared sensor of the lighting control unit senses movement of a person or an object; the micro-controller 1 of the lighting control unit gradually increases the brightness of the lighting device 4 to 100% by controlling the dimming driver 5; the lighting control unit sensing the movement of the human body is defined as No. 1 lighting control unit; the micro-controller 1 of the No. 1 lighting control unit sends the signals including the number of the groups, lighting levels and holding time to the peripheral lighting control units within the radius of the concentric circle through the infrared transceiver modules; the lighting control units receiving the signals are the No. 2 lighting control units; the No. 2 lighting control units automatically form a concentric circle and constitute a first lighting control unit group, and then all the No. 2 lighting control units in the first lighting control group send the signals outwards as well. lighting control unit groups constituted by 1-9 concentric circles are formed outside the No. 1 control units in the same way. The outward infrared broadcast communication distance of the lighting control units has a certain matched relationship with the installation height of the lighting control units. Centered on the lighting control unit sensing the movement of the object, the lighting control units in the total nine lighting control unit groups from the first to the ninth automatically identify which groups the lighting control units are in and keep preset lighting. The preset lighting is 0% - 100%, and the holding time is Is (second) - 24h (hours). [0031] Specifically, refer to Fig. 2 for the first case, wherein the lighting of the first lighting control unit group is set as 80%; the lighting of the second lighting control unit group is set as 40% ; and the lighting of the other lighting control unit groups at the outer end of the second lighting control unit group is set as 0% (put out). When the human body detecting sensor of the No. 1 lighting control unit senses the movement of the object, all No. 2 lighting devices 4 of the first lighting control unit group will light up with 80% dimming level ; all No. 3 lighting devices 4 of the second lighting control unit group will light up with 40% dimming level; and all the other lighting devices 4 will maintain the automatic put-out status. Regarding the holding operation over the set time, the micro-controllers 1 control the lighting devices 4 to maintain the already set dimming level all the time. [0032] Refer to Fig. 3 for the second case. When the object moves, for example, the object moves from the original position of the No. 1 lighting control unit to the position of the No. 2 lighting control unit in the Figure, the No. 2 lighting control unit changes into the No. 1 lighting control unit at the moment when the human body detecting sensor 8 of the No. 2 lighting control unit senses the movement, which means that, the No. 2 lighting control unit serves as the lighting control unit at the circle center, that the micro-controller 1 of the No. 2 lighting control unit automatically transmits the center moving signal to the peripheral lighting control units through the infrared transceiver module 10, and that new nine lighting control unit groups are formed around the new No. 1 lighting control unit as the center. The lighting settings changes are as follows: when the lighting of the first lighting control unit group is set as 80%, the that of the second lighting control unit group set as 40% and the other lighting control unit groups at the outer end of the second lighting control unit group as 0% (put out). In the moving status of the central lighting control unit, the lighting of the original No. 2 lighting control unit is changed from 80% to 100%, the lighting of the original No. 1 lighting control unit is changed from 100% to 80%, the lighting of the No. 3 lighting control units originally located in the second lighting control unit group are located in the first one of the newly formed lighting control unit groups and therefore has corresponding lighting of 80%. The other lighting control units are set and respond with the matched illuminance. [0033] The third case is mostly multi-point touch sensing. Refer to Fig. 4. If movement of people is captured at different places at the same time, two or more lighting control units broadcast at the same time to form the corresponding lighting control unit groups centered on respective lighting control units. According to the settings of the lighting control system, the lighting control units sensing the movement of the objects will be automatically set as the lighting control unit group with the largest number without any conflicts. With reference to the Figure, the dimming level of the first concentric circle is set as 80%; the second concentric circle is set as 40%, and all the other concentric circles outside the second concentric circle are set as 0% in the put-out state of the lighting devices 4. Refer to Fig. 4. In the first lighting control unit group centered on the lighting control unit which senses the movement of the human body from the left side, the lighting of the No. 2 lighting control units is needed to be set as 80%; the lighting of the No. 3 lighting control units (located in the second lighting control unit group) is needed to be set as 40%; and the No. 4 lighting control units and on the rest are all put out. In the lighting control unit groups centered on the lighting control unit which senses the movement of the human body from the right side, the lighting corresponding to the No. 4 lighting control units and the No. 6 lighting control units is in the put-out status However, the lighting control units receive the signals sent by the central lighting control unit from the left side and are located in the first one of lighting control unit groups formed on the left side, in other words from the central lighting control unit on the left side, and the No. 4 and No. 6 lighting control units are located in the first lighting control unit group, namely the No. 2 lighting control units, therefore the 80% dimming lighting can be maintained, and the lighting corresponding to the No. 3 lighting devices 4 can also be maintained at 40%. It is needed to be explained that, even if the lighting control unit groups in a composite concentric circle are generated due to the fact that several different sensing centers are generated in the same space, the lighting of the lighting devices 4 can also be maintained according to the highest priority of the lighting levels, wherein the highest priority means that a certain lighting control unit can have the highest lighting level by means of the broadcast information received. [0034] The lighting control system is initially set as below: the dimming or put-out status and holding time in a lighting control unit by utilizing an application program of a remote controller or an intelligent cell phone; then, by using the Broadcast function of the application program in the remote controller or the intelligent cell phone, the initially set lighting control unit automatically transmits the initially set contents to all lamps in the same space like concentric ripples waving on the lake surface through the infrared transceiver module; the micro-controllers 1 of the peripheral lighting control units automatically saves the received set contents; the lighting control units automatically start running according to the set contents after the contents are saved, and the contents do not disappear after power failure. In practical use, the setting contents of all the lamps in the same space can also be changed through the same Broadcast method if even the settings are changed. In order to complete the initial settings, it is required to utilize the wireless remote controller or the intelligent cell phone to execute and complete settings at night without solar light. The fully-automatic infrared wireless lighting control system can be applied to 0-1OVDC or 1-1OVDC dimming stabilizers or be used for connection of various types of lighting devices 4 using drivers. [0035] The above are not to limit the technical scope of the utility mode. Any changes, equivalents or modifications made to the embodiments according to the technical essence of the utility model shall still fall within the scope of the technical scheme of the utility model.
