Same led lighting module, provides different driving currents, realizes driving the led of different capacity.
Described master control circuit board has detection led lighting module both end voltage and drives led function, and be also stored with difference
The corresponding driving current data of voltage led lighting module.
The effect of described mcu is just used to detect and judge the classification of LED lamp group, controls led to drive electricity according to voltage
The output current on road.
One two core socket is had on described master control circuit board, two pins of this socket are the driving electricity of led
Stream interface, is also detection mouth.
Described master control circuit board, can be driven to LED lamp and dim, and store the bright of various led lighting modules
Degrees of data.
Pin on two core plugs of two described core sockets and led lighting module is corresponding.
Described led lighting module connecting cable, cable has plug；Cable plug connects master control circuit board
Socket.
Described radiator had both supplied led to radiate, and was also the shell of led lighting module.
Advantage:
The present invention relates to one kind can provide different electric currents according to specific led combination, realize on same socket
What the led of different capacity powered judges different led lighting modules according to voltage.
Present configuration is simple, practical, provides led well and changes efficiency.
Brief description
Accompanying drawing described herein is used for providing patent of the present invention is further understood, and constitutes of patent of the present invention
Point, the schematic description and description of patent of the present invention is used for explaining patent of the present invention, does not constitute to patent of the present invention
Improper restriction.In the accompanying drawings:
Fig. 1 is one 3 watts led lighting module electrical schematics.
Fig. 2 is two 2 watts led series lighting module electrical schematics.
Fig. 3 is 48 0.06 watt led lighting module electrical schematic.
Fig. 4 is master control circuit board theory diagram.
Specific embodiment
The present invention is further illustrated with instantiation below in conjunction with the accompanying drawings.
As shown in Fig. 1,4, a kind of judge different led lighting modules according to voltage, by master control circuit board 4, led illumination
Module, two core connector compositions；Master control circuit board 4 has detection led lighting module both end voltage and drives led function, also deposits
Contain the corresponding driving current data of different voltage led lighting modules；Led lighting module is by LED lamp 1, substrate and 2 groups of radiator
Become, led lighting module is connected composition loop with master control circuit board 4；Led lighting module passes through cable and socket and main control electricity
After road plate 4 connects, master control circuit board 4 judges different led lighting modules by detecting the voltage of led luminaire, provides
Different driving currents, thus realize driving the led of different capacity.
One two core plug 3 is had on led lighting module, two pins of plug are connected to positive pole and the negative pole of LED lamp 1,
It is the driving interface of LED lamp 1.
As shown in figure 4, being master control circuit board 4 theory diagram of this example, master control circuit board 4 there is led drive electricity
Road and a microcontroller mcu, the effect of mcu is just used to detect and judge the classification of LED lamp group, controls led according to voltage
The output current of drive circuit.One two core socket 5 is had on master control circuit board 4, two pins of this two cores socket 5 are
The driving current interface of led, is also detection mouth.This two cores socket 5 is relative with the pin on two core plugs 3 of led module
Answer.
Mcu control after the plug 3 of led lighting module inserts socket 5 of master control circuit board 4, in master control circuit board 4
Led processed drives, the Constant Electric Current being less than 5 milliamperes to the output of led lighting module by two pins of two core sockets 5 on circuit board
Stream, and then detect the voltage of this led lighting module, according to the characteristic of white light led, forward voltage when only one of which led
It is between 2.8v ~ 3.5v, when two led series windings, forward voltage is between 5.6v ~ 7v, positive when three led series windings
Voltage is between 8.4v ~ 10.5v；Mcu was just originally corresponded to default current value according to different magnitude of voltage couplings and was sent to led
On drive circuit, led drives the pipe just connecting LED lamp 1 positive pole and negative pole according to this current value by socket 5 on plug 3
Pin, thus realize driving corresponding LED lamp 1.
As shown in figure 1, situation when using 13 watts of led；As shown in Fig. 2 being the situation that two 2 watts of led connect, such as
Shown in Fig. 3, it is 48 0.06 watt of led connection diagrams.So when plug 3 and the master control circuit board of these different in figures
After 4 socket 5 connects, master control circuit board 4 just can be judged different lighting modules, provide not according to different voltage
Same electric current；
As shown in figure 1, being 13 watts of led, the electric current of use is 700 milliamperes；As shown in Fig. 2 being two 2 watts of led string
Even, the use of electric current it is 500 milliamperes；As shown in figure 3, being 3 strings 16 and combine of 48 0.06 watt of led, the use of electric current is 320 millis
Peace.
The led lighting module so making various power has different forward voltages, you can to obtain presetting corresponding drive
Streaming current.When user prepares to change lighting module, directly the plug 3 of lighting module is inserted in master control circuit board 4 socket 5
?.So can achieve plug and play, need not in addition dose any switching mechanism or change drive circuit.
