The UV-B LED 50 can use Seoul VIOSYS CA3535 series and LG Innotek 6060 model, and SEOUL VIOSYS CA3535 series CUD1GF1A model has It has a peak wavelength of , and the 6060 model of LG Innotek has a peak wavelength of 300 to 310 nm.

The reflector 60 is coupled to the guide 23 or to the individual frame 110, and is plate-shaped in the longitudinal direction, and the flange 64 and the bottom surface transmit UV-B emitted from the UV-B LED 50. A penetration hole 62 penetrated up and down at a position corresponding to the UV-B LED and an inclined surface 63 extending from the penetration hole 62, that is, extending from the top to the bottom, are configured to become wider. The UV-B has very weak penetrating power, so it cannot be transmitted if there is a medium or cover except for quartz in the middle. When fully exposed, a person's hand can come into contact with the terminal part of the UV-B LED 50, so that a person can get an electric shock due to careless use or installation, so the reflector 60 increases safety against electric shock. .

The penetration hole 62 is configured at a position corresponding to the UV-B LED 50 and is configured the same as the number of UV-B LEDs 50, and the center of each reflector 60 is an individual reflector 60 It is configured to substantially coincide with the center of each UV-B LED 50 corresponding to . It is effective that the cross section of the penetration hole 62 is the same as the plane of the UV-B LED 50 . Since the plane of the UV-B LED 50 is rectangular, the cross section of the penetration hole 62 is preferably rectangular, but it is also possible to have a circular cross section.

The UV-B has a characteristic of not transmitting UV radiation having a wavelength of 280 to 315 nm having a high energy level or materials other than quartz. In the position corresponding to the UV-B LED 50 in the reflector 60, quartz should be formed so that the UV-B emitted from the UV-B LED 50 is transmitted. To this end, the reflector 60 is entirely made of quartz or if the penetration hole 62 and the inclined surface 63 are made of quartz and the rest is made of plastic, that is, the reflector 60 in which quartz is inserted, the price of quartz is expensive and the manufacturing cost is high, so it is economically and practically preferable. will not do Therefore, a penetration hole 62 is formed at a position corresponding to the UV-B LED 50 in the reflector 60 .

The inclined surface 63 protrudes upward from the inner bottom surface of the reflector 60 and is embraced by the housing 20 or the reflector 60 to make the bottom surface of the reflector 60 beautiful. The inclined surface 63 is configured to be wider, that is, to be expanded, from the top to the bottom of the through hole 62, and toward the front from the edge of the through hole 62, that is, the UV-B light emitted from the UV-B LED 50 It is configured to gradually expand along the direction in which B is projected. The inclined surface 63 is composed of an inclined surface 63 extending outward from the center of the transmission hole 62 in the direction in which UV-B is projected.

The overall shape formed by the inclined surface 63 and the through hole 62 is a pyramid shape cut when the through hole 62 is formed in a square shape, and the through hole 62 is formed in a circular shape. In this case, the conical cylinder is in a cut shape, and according to the shape of the through hole 62, it may be configured in a cut cylinder corresponding to it. The cut pyramid or cone is configured to protrude from the lower surface of the reflector 60 in the direction of the UV-B LED 50, and the end of the pyramid or cone is approached and the UV-B LED 50 is cut. The pyramid or cone, that is, the inclined surface 63 and the penetration hole 62 minimize interference of light emitted from the UV-B LED 50.

Since the wide angle of UV-B emitted from the UV-B LED 50 is 120°, the inclination angle of the inclined surface 63 is 115 to 125°, preferably 120°. When the inclination angle of the inclined surface 63 is 115° or less, part of the UV-B light emitted from the UV-B LED 50 is reflected by collision with the inclined surface 63, and the wide angle of UV-B is reduced to irradiate UV-B. The area is reduced, and when the angle of inclination of the inclined surface 63 is 125 ° or more, the wide angle of UV-B is not reduced, but the portion of the reflector 60 where the thickness is reduced increases, so that the reflector with the inclined surface 63 ( 60) is lowered. The size of the UV-B penetration hole 62 and the angle of inclination of the inclined surface 63 can maximize the UV-B light emitted from the UV-B LED 50 while maintaining the maximum intensity of the reflector 60. It is composed of

In the reflector 60, the lower boundary of the inclined surface 63 extending to the transmission hole 62 and the inclined surface 63 extending to the adjacent transmission hole 62, that is, the belt surface 65 is a strip-shaped plane, and the belt surface (65) is connected to the same plane as the flange (64). For example, the through hole 62 is composed of four pieces of a first through hole, a second through hole, a third through hole, and a fourth through hole, and the first through hole, the second through hole, the third through hole, When the line connecting the fourth through-hole forms a square, that is, when the first through-hole, the second through-hole, the third through-hole, and the fourth through-hole are formed at each corner of the imaginary square, the first through-hole, the The belt surface 65 of the lower boundary where the four inclined surfaces of the second through hole, the third through hole, and the fourth through hole meet is composed of a +-shaped surface and is connected to the same plane as the flange 64. When the penetration holes 62 are composed of 6 pieces in 2 rows and 3 rows, the band surface 65 of the lower boundary where the inclined surface 63 meets is composed of a ╊╊-shaped surface, and the ╊╊ surface is in the same plane as the flange 64. connection is made up.

In the present invention, a controller (IC, 220) is configured to control lighting LEDs 40, UV-A LEDs 130, and UV-B LEDs 80 on and off. The controller (IC, 220) includes Vref and internal bias, undervoltage cutoff, internal OTP (Over-Temperature Protection), undervoltage cutoff, blanking time, switch (SW1, SW2) controller, VDD pin overvoltage protection (VDD pin Over-Voltage Protection) ), frequency foldback, VDD clamp, triangular wave oscillator, clock generator, filter and comparator, etc., maximum gate driving output clamp function, VDD terminal overvoltage protection function, current limiting function per cycle, LED overcurrent protection function Switch (SW1), switch (SW2), DRV terminal, GND terminal, COMP terminal, FB terminal while performing functions such as LED open loop protection function, LED short circuit protection function, and internal temperature over temperature protection function , CS terminal, VDD terminal, CLK terminal, etc.

The controller (IC, 220) turns on all of LED1, LED2, and LED3, simultaneously turns on LED1 and LED2, or lights only LED3 whenever the switch is turned ON/OFF.

SW1 of the controller (IC) 220 outputs control signals for LED1 and LED2 to operate the MOSFET transistor Q1, and SW2 outputs a control signal for LED3 to operate the MOSFET transistor Q2. In the controller (IC, 220), a switch controlling unit (SW1/SW2 Control) is connected to an external CLK terminal, a switch (SW1), and a switch (SW2). The CLK terminal senses the CLK signal of an external switch and applies a signal to the switch control unit (SW1/SW2 Control) so that the switch control unit (SW1/SW2 Control) is a MOSFET transistor (field effect transistor (FET: field effect transistor, Q1] and the on/off of the transistor Q2 are determined, and LED1 and LED2 are turned on by the number of repetitions of the on/off of the switch, and LED3 is individually turned on. Lights up selectively.

When only the MOSFET transistor (Q1) is turned on, LED1 and LED2 emit light, and when only the MOSFET transistor (Q2) is turned on, LED3 emits light, and both the MOSFET transistor (Q1) and the MOSFET transistor (Q2) are turned on at the same time LED1, LED2, and LED3 emit light at the same time. When AC power is converted to DC power through a bridge rectifier (BR: Bridge Rectifer, 210) and supplied to VDD of the controller (IC, 220), the controller (IC, 220) starts operating, and the DRV terminal operates as a driving circuit. By activating the MOSFET transistor in 200, the entire driving circuit 200 is activated, and LED1, LED2, and LED3 emit light.

The CLK terminal receives the on/off of the switch from the outside of the controller (IC, 220) as a CLK signal, operates the switch control unit (SW1/SW2 Control), and operates the switch control unit (SW1/SW2 Control) determines the switches SW1 and SW2 to control the driver. The alternating current (AC) power is converted to direct current (DC) through a bridge rectifier (BR, 210) and supplied to the input terminal of the circuit. With the supply of the direct current (DC) power, power is supplied to the VDD terminal of the controller (IC, 220) and the controller (IC, 220) operates, and the DRV terminal operates the external MOSFET transistor (Q1) to operate the entire driving circuit 200 is activated to induce the operation of LED1, LED2 and LED3.

The output current of the driving circuit 200 can cause LED1, LED2, and LED3 to emit light, but the cathode part of the connection of LED1, LED2, and LED3 is connected to the switching MOSFET transistors (Q1, Q2) to turn on the switching of the MOSFET transistors (Q1, Q2). Since the closed circuit of LED1, LED2, and LED3 is formed only in the (On) state, the light emission state of LED1, LED2, and LED3 emits (lights) when the MOSFET transistors (Q1, Q2) are on, and the MOSFET transistors (Q1, Q2) ) is off, it is controlled to not emit light (turn off).

The CLK terminal is applied with the CLK signal by DC input through the bridge rectifier (BR, 210) by the on/off of the switch, and the CLK terminal detects the CLK signal according to the presence or absence of the DC input to control the controller. A signal is applied to the switch control unit (SW1/SW2 Control) of (IC, 220). The voltage level of the COMP terminal determines the on time of the power switch and adjusts the energy of the transformer T1. The higher the voltage of the COMP terminal, the greater the duty cycle of driving, so that the illumination of LED1, LED2 and LED3 increases. The controller (IC, 220) integrates the compensated blanking-off time according to the voltage signal of the COMP terminal, and when the input voltage becomes higher or the load is lighter, the signal of the COMP terminal decreases and in the ZCD circuit of the controller (IC, 220) A longer blank-off time occurs, reducing the operating frequency and improving efficiency.

When the switch is turned on, the AC voltage is converted to DC power through the bridge rectifier (BR, 210) and supplied to the circuit for the first time. 220) operates to start a switching operation, and LED1 and LED2 are turned on by the MOSFET transistor Q1 (SW1 signal). The controller (IC, 220) outputs a DRV duty signal with an appropriate turn-on time, and LED1, LED2, and LED3 adjust the current to the current set level, and the MOSFET transistor (Q1) (SW1 signal) initially While turned on, the MOSFET transistor Q2 (SW2) is turned off.

When the switch is turned off and the AC input voltage is removed, both the VDD and CLK terminal voltages are reduced to activate the internal timer of the controller (IC, 220) and turn off the MOSFET transistor (Q1). When the switch is turned on, DC power is supplied to the driving circuit 200 again, and when the VDD voltage rises, the controller (IC, 220) operates to start a switching operation, and the MOSFET transistor Q2 (SW2 signal) LED3 is turned on by The voltage of the current of LED3 is compared with the internal reference voltage, and the controller (IC, 220) outputs a DRV duty signal with an appropriate turn on time to adjust the current to the current set level of LED3 and the MOSFET transistor ( While Q2 (SW2 signal) is turned on, the MOSFET transistor (Q1) (SW1) is turned off.

When the switch is turned off and the AC input voltage is removed, both the VDD and CLK terminal voltages are reduced, the internal timer of the controller (IC, 220) is activated, and the MOSFET transistor (Q2) is turned off. When the DC power is supplied again to the driving circuit 200 by the on of the switch, the controller (IC, 220) operates to start a switching operation, and the MOSFET transistors Q1 and Q2 (SW1/SW2 signals) LED1, LED2 and LED3 are turned on by The detected voltages of the currents of LED1, LED2, and LED3 are compared with the internal reference voltage, and the controller (IC, 220) outputs a DRV duty signal with an appropriate turn-on time so that LED1, LED2, and LED3 are currently While the current is adjusted to the set level and the MOSFET transistor Q1 (SW1 signal) is turned on, the MOSFET transistor Q2 (SW2) is also turned on. When the switch is turned off and the AC input voltage is removed, both the VDD terminal and CLK terminal voltages are reduced to activate the internal timer of the controller (IC, 220), and the MOSFET transistors (Q1 and Q2) are both turned off. )do.
