The technique scheme of passing through of the present utility model, this LED lamp can transmit the work operation conditions of data message such as the brightness of LED lamp, temperature and power circuit by serial interface and arrive remote control center, and can receive that this control centre sends over to LED lamp and power circuit control signal, can realize monitoring to the LED lamp, use more convenient operation, but also can reach better effects of energy conservation and environmental protection.
[description of drawings]
Fig. 1 is the structured flowchart with LED light fixture of serial interface described in the utility model.
Below in conjunction with accompanying drawing technical solutions of the utility model are elaborated.
See also Figure of description Fig. 1.The LED light fixture 100, LED lamp 101, control circuit 102, feedback module 1021, receiver module 1022, sensing module 1023, serial interface 103, the power circuit 104 that have serial interface among the figure.
As shown in FIG.:
The utility model provides a kind of LED light fixture 100 with serial interface, and this light fixture 100 is the LED lamp, includes LED lamp 101, control circuit 102, serial interface 103 (as the DB9 interface) and power circuit 104.Wherein,
LED lamp 1 is made up of 5 lamp pearls (photoelectron good as Shenzhen, model are CREE XPE) that employing is welded on the circuit board, and is connected with control circuit 2 conductings.
Control circuit 102 includes feedback module 1021, receiver module 1022 and sensing module 1023.Feedback module 1021 is connected with LED lamp 101, is mainly used in the constant current output of maintenance to LED lamp 101; The corresponding connection of output 3,4,7 signal pins of the input of receiver module 1022 and serial interface 103, the output of receiver module 1022 is connected with the input of LED lamp 101 and the input of power circuit 104, be mainly used in and receive the data-signal that serial interface 103 transmits, and send to LED lamp 101 and/or power circuit 104; Sensing module 1023 mainly is made up of photo resistance sensor and thermistor (temperature) sensor, its input is connected with the output of LED lamp 101, the corresponding connection of input 1,2,6 signal pins of output and serial interface 103, be mainly used in the brightness and the temperature information that detect LED lamp 101 and be sent on the serial interface 103, be transferred to remote control center by the external equipment (as EPON ONU equipment) that is connected with serial interface 103 again.
Power circuit 104 includes by civil power and transfers the dc voltage circuit of positive 15V to and transferred to the dc voltage circuit of positive 2.5V by civil power, and be used to control these two groups of transforming circuits and to the power control electrical chip (, not showing among the figure) of control of LED lamp 1, control circuit 2 as the LNK406 chip; This power circuit 104 all is connected with feedback module 1021, receiver module 1022 and sensing module 1023, the supply of the power supply that is used to finish the work.
During the utility model running, remote control center is transferred to control signal (as the On/Off of control power circuit) on the serial interface 103 that is attached thereto by Ethernet (as EPON), be transferred to receiver module 1022 then, be transferred to LED lamp 101 and/or power circuit 104 after treatment, electric current on 1021 pairs of LED lamps 101 of feedback module carries out constant current control simultaneously, sensing module 1023 is the brightness of LED lamp 101, after data message such as temperature and duty detects, be sent on the serial interface 103, arrive remote control center at last, can monitor the LED lamp according to this data message, use more convenient operation, but also can reach better effects of energy conservation and environmental protection.
Certainly, LED lamp 101 can be the other types illuminating lamp also, as incandescent lamp.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
