4 is a diagram comparing the circuit scheme of a switching power supply (AC-DC converter).

The circuit method of the conventional switching power supply (AC-DC converter) is a flyback method, a forward method, a push-pull method, a half-bridge method, and a full-bridge method.

The flyback method is a circuit method that accumulates power in the inductor when the switching element is ON and outputs this power when it is OFF. It is not suitable for models with large output power capacity and is used in small capacity models. It has the advantage of ensuring a wide input voltage range, but has a disadvantage in that a relatively large peak current flows through the switching element and the inductor. The Ringing Choke Converter (RCC) method is a type of flyback method.

The forward method is a circuit method that transfers power from the primary side to the secondary side when the switching element is ON, and is used for many switching power supplies because the circuit configuration is simple and stable control is possible. It is used not only for models with a small output power capacity, but also for relatively large models. Although high power conversion efficiency can be obtained, there is a drawback that the amount of noise generated in the MHz band is large.

The push-pull method is a circuit method in which two transformers are alternately used by using two switching elements. Since the use efficiency of the transformer is increased, it can be applied to a model having a relatively large output power capacity.

The circuit operation of the half-bridge method is the same as that of the push-pull method, but since the voltage applied to the transformer is lower than about half of the input voltage, there is an advantage that a variety of low withstand voltage can be used as a switching element. It is applicable to models with large output power capacity and is used for models up to 1kW.

The full bridge method is a circuit method in which the input portion of the half bridge method is changed to a full bridge, and the advantage of using a switching element having a low withstand voltage is similar to that of the half bridge method, but the circuit configuration and control are more complicated than the half bridge method. . High power conversion efficiency can be obtained. It is applied to a power source having a large output power capacity.

(S60) remote ON / OFF control of the LED luminaire, and further comprising a step of performing dimming control (dimming control, dimming control) controlling the brightness at the on and off duty ratio according to the PWM signal (S70).

In the above method, since a person does not exist at the time of going out or vacation using the app on the smartphone, if the UV LED ON / OFF and the LED for general lighting are turned off for a certain period of time (from-to), the smartphone is set Data is transmitted to a dedicated LED converter and stored in a storage unit connected to the control unit of the LED lighting control device, and by operating a timer connected to the control unit, the LED lighting control device according to the setting data of the smartphone automatically according to the preset setting data It further comprises the step of providing a reservation function.

In the above method, when the wireless communication unit in the form of separation to the LED-only converter breaks down, the failure diagnosis data is transmitted to the smartphone, and when the wireless communication unit module is detached from the LED-only converter when the wireless communication unit malfunctions, the wireless communication unit module is automatically removed. Further comprising the step of providing the same function as the normal lighting so that only the ON / OFF of the LEDs for general lighting is turned off by the LED lighting control device.

The sensor uses one of a microwave (M / W) Doppler sensor, an IR sensor, a human body detection (PIR) sensor, an ultrasonic sensor, or a proximity sensor.

The dimming control uses a pulse width modulation (PWM) for a constant driving current of the LED to change the dimming control of the LED by changing the duty cycle of the current pulse to a size of 3 to 4 times the average light output.
