[0014] Figure 2 This is a control block diagram of a lamp bead series circuit of a lamp bead anti-circuit breaking control module provided by an embodiment of the present utility model; DETAILED DESCRIPTION
[0015] The lamp head of the spectrum therapy device is composed of several lamp boards in parallel, and each lamp board has the same function. The lamp board is composed of several lamp beads in series circuit in parallel, and each lamp bead series circuit has the same function. The lamp bead series circuit is composed of several lamp beads, current detection modules, and anti-circuit-breaking control modules; each lamp bead has an anti-circuit-breaking control module in parallel at both ends, and the main control MCU can control the anti-circuit-breaking control module to achieve short circuit at both ends of the corresponding lamp bead. In addition, the main control MCU realizes current detection of the circuit through the current detection module.
[0016] like Figure 1 As shown, the present invention provides a lamp bead anti-disconnection control module. The anti-disconnection control module is connected in parallel to both ends of the lamp bead. The anti-disconnection control module includes a voltage regulating unit, a diode D1 connected to the voltage regulating unit, a voltage maintaining unit connected to the voltage regulating unit and diode D1, and a lamp bead LED1-1 having its cathode connected to the voltage maintaining unit, and its anode connected to the anode of the lamp bead. The anti-disconnection control module uses the voltage regulating unit to generate a voltage signal that turns on the voltage maintaining unit. The voltage maintaining unit is used to maintain the conduction voltage, allowing LED1-1 to be connected to the series lamp bead circuit, thereby replacing a damaged lamp bead and maintaining continued operation.
[0017] The voltage regulating unit includes a transistor Q4, a diode D2, a capacitor C1, a relay switch SW1 and a relay switch SW2. The base of the transistor Q4 is connected to the main control MCU, the emitter of the transistor Q4 is connected to the positive electrode of the power supply, the collector of the transistor Q4 is connected to the positive electrode of the diode D2, the cathode of the diode D2 is respectively connected to the positive electrode of the diode D1 and one end of the capacitor C1, the other end of the capacitor C1 is respectively connected to one end of the relay switch SW1 and one end of the relay switch SW2, and the other end of the relay switch SW1 is connected to GND.
[0018] The voltage maintaining unit includes a capacitor C2, an electron R1 and a field effect transistor Q1. The gate of the field effect transistor Q1 is respectively connected to one end of the resistor R1, one end of the capacitor C2 and the cathode of the diode D1. The source of the field effect transistor Q1 is respectively connected to the other end of the relay switch SW1 and the cathode of the lamp bead. The drain of the field effect transistor Q1 is connected to the cathode of the lamp bead led1-1. The other end of the capacitor C1 and the other end of the resistor R1 are both connected to GND.
[0019] The working process of the anti-circuit-break control module is as follows:
[0020] Step 1. In the normal state, the relay switch SW1 and the relay switch SW2 of the anti-circuit-breaking control module are disconnected. The base of the transistor Q4 (i.e. G1-1) is controlled by the main control MCU to output a high level. At this time, the voltage at the cathode of the diode D1 (i.e. G1) is 0v, the field effect tube Q1 is turned off, and the current flows through the lamp bead 1.
[0021] Step 2: When it is necessary to short-circuit lamp bead 1, G1-1 outputs a low level. At this time, transistor Q4 is turned on, relay switch SW1 is disconnected, relay switch SW2 is turned on, and the voltage at the connection point of capacitor C1 and diode D1 is U1=5v-(diode D2 voltage drop)=5v-0.7v=4.3v.
[0022] Step 3, G1-1 outputs a high level, at which time the field effect tube Q4 is turned off; the relay switch SW1 is turned on and the relay switch SW2 is turned off. At this time, the voltage at the connection point between the capacitor C1 and the diode D1 is U2=U1+U(Q1-S) (Note: U(Q1-S) indicates that the voltage at the S terminal of the MOS tube Q1).
[0023] Step 4. At this time, U(Q1-G)=U2-U(D1)=U2-0.7v=U1+U(Q1-S)-0.7v; (the voltage drop of diode D1 is 0.7v), the voltage difference across GS of field effect tube Q1 is U(Q1-G)-U(Q1-S)=U1-0.7v=4.3v. At this time, field effect tube Q1 is turned on, and current passes through lamp bead led1-1, and field effect tube Q1 achieves the purpose of short-circuiting lamp bead 1.
[0024] Relay switch SW1, relay switch SW2, and G1-1 periodically execute the above steps 2 and 3 to stably turn on G1. Note that the lamp bead led1-1 is of the same type as the lamp bead 1.
[0025] The following table is used to describe the changes in control signals in normal state and when the lamp bead 1 needs to be short-circuited:
[0026]
[0027] A spectrum therapy device, which includes the anti-circuit-breaking control module, and also includes a main control MCU, a constant current source, a current detection module and a lamp holder. The anti-circuit-breaking control module is connected to the main control MCU and the lamp holder, the current detection module is connected to the main control MCU and the lamp holder, and the lamp holder is connected to the constant current source.
[0028] The lamp holder includes a plurality of lamp boards connected in parallel, the lamp boards include a plurality of lamp bead series circuits connected in parallel, the lamp bead series circuit includes at least two lamp beads, and the anti-circuit breaking control module is connected in parallel at both ends of each of the lamp beads.
[0029] like Figure 2As shown, in normal operation, each lamp bead series circuit is connected with a current detection module, and the current of each lamp bead series circuit is detected by the current detection module. Assume that the current i1 on one of the lamp bead series circuits is 1a. When the lamp bead in the lamp bead series circuit is damaged and the circuit is broken, the current on the lamp bead series circuit is i1=0a. At this time, when the main control MCU detects the current i1=0a, it starts to execute the detection program, enables the anti-circuit control module 2 to the anti-circuit control module n, and short-circuits the corresponding lamp bead 2 to lamp bead n. At this time, the constant The current source circuit is only connected to lamp bead 1. If i1=1a at this time, it means that lamp bead 1 is not damaged. If i1=0a, it means that lamp bead 1 is damaged. Enable other anti-circuit breaking control modules except anti-circuit breaking control module 2, so that the constant current source circuit is only connected to lamp bead 2. If i1=1a at this time, it means that lamp bead 2 is not damaged. If i1=0a, it means that LED2 is damaged. Through the above process, the damaged lamp bead in the lamp bead series circuit is detected, and the anti-circuit breaking control module corresponding to the damaged lamp bead is enabled, so that the current lamp bead series circuit can continue to work.
[0030] This anti-circuit-break control module is connected in parallel to each lamp bead in the series, so that no matter which lamp bead in the series has a problem, the lamps can continue to work normally, and the problem of the entire series lamp bead not working due to damage to a certain lamp bead will not occur. At the same time, the spectrum therapy device connects the anti-circuit-break control module in parallel to each lamp bead, so that the light board of the spectrum therapy device can continue to provide treatment even if some lamp beads are damaged. In addition, this anti-circuit-break control module has a simple structure and low cost.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
