Drawings
Fig. 1 is a structural diagram of an LED driving control apparatus according to an embodiment of the present invention.
Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
To explain the LED driving control device provided by the present invention in detail, fig. 1 shows a structure based on the LED driving control device according to an embodiment of the present invention.
As shown in fig. 1, the LED driving control device provided by the present invention includes an LED lamp group composed of LED lamps, a single chip microcomputer 2, and a driving module corresponding to the LED lamp group. The LED lamp sets are four groups, namely P0, P1, P2 and P3, the driving modules corresponding to the LED lamp sets are four, namely L1, L2, L3 and L4, the single chip microcomputer comprises four groups of I/O ports, namely Y1, Y2, Y3 and Y4, and each group of I/O ports is connected with one group of LED lamp sets and one driving module through leads; in an example of the invention, the single chip microcomputer 2 is an STC89C52 type single chip microcomputer, each group of I/O ports is composed of 8 single chip microcomputer pins, and each group of LED lamps is composed of 8 LED lamps. Namely: 8 LED lamps in P0 are connected with Y1 and L1 through lead wires, 8 LED lamps in P1 are connected with Y2 and L2 through lead wires, 8 LED lamps in P2 are connected with Y3 and L3 through lead wires, and 8 LED lamps in P3 are connected with Y4 and L4 through lead wires.
The four groups of LED lamp groups (P0, P1, P2 and P3) are controlled by the singlechip 2 in turn, and only one group of LED lamp group is lighted at each moment. It should be noted that, because the current of the single chip microcomputer is small, the LED lamp cannot be driven to be turned on, and therefore, a driving circuit (i.e., a driving module) needs to be added to drive the LED lamp to be turned on. Namely: the driving module converts the small current output by the I/O port of the singlechip into large current (amplifies the output current) so as to drive the corresponding LED lamp group to be lightened.
In addition, the present invention also provides a method for driving and controlling an LED by using the LED driving control device, and a driving control process of the LED driving control method provided by the present invention will be described in detail below.
The drive control process of the LED drive control device provided by the invention comprises the following steps:
1. the LED lamp bank, the I/O port of the singlechip and the driving module are correspondingly connected through leads;
2. the singlechip controls the four groups of LED lamp groups in turn, and only one group of LED lamp group is allowed to be lightened at each moment.
3. The current output by the I/O port of the singlechip is amplified through the driving module so as to drive the corresponding LED lamp group to be lightened.
Wherein, the control process of singlechip is: the four groups of LED lamp groups are controlled in turn, the lighting time of each group of LED lamp groups is set, only one group of LED lamp groups are lighted within the set lighting time, and the rest three groups of LED lamp groups are all in a non-lighting state.
In one example of the present invention, four sets of LED light sets may be controlled in turn by the following procedure to ensure that only one set of LED light sets is illuminated during a set illumination time. The procedure was as follows:
according to the LED drive control device and the control method provided by the invention, the four groups of LED lamp groups are driven and lightened in turn by the drive module through the four groups of I/O ports of the single chip microcomputer, and the effect of lightening the four groups of LED lamp groups simultaneously is generated by using the visual persistence effect of human eyes, so that the aim of further saving energy is fulfilled while the illumination effect is ensured.
The LED driving control apparatus and the control method according to the present invention are described above by way of example with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various modifications can be made to the LED driving control apparatus and the LED driving control method of the present invention without departing from the scope of the present invention.
