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. At a position corresponding to the UV-B LED 80 in the reflector 90, quartz should be formed so that the UV-B emitted from the UV-B LED 80 is transmitted, but for this, the reflector 90 When the whole is made of quartz or the through hole 92 and the inclined surface 93 are made of quartz and the rest is made of plastic, that is, when the reflector 90 in which quartz is inserted is made of quartz, the price of quartz is expensive and the manufacturing cost is high, so it is economical, Practically undesirable.

The inclined surface 93 protrudes upward from the inner bottom surface of the reflector 90 and is embraced by the vertical portion 91 of the reflector 90, making the bottom surface of the reflector 90 beautiful. The inclined surface 93 is configured to be wider, that is, to expand, from the top to the bottom of the through hole 92, and toward the front from the edge of the through hole 92, that is, the UV-B light emitted from the UV-B LED 80 It is configured to gradually expand along the direction in which B is projected. The inclined surface 93 is composed of an inclined surface 93 extending outward from the center of the transmission hole 92 in the direction in which UV-B is projected.

The overall shape formed by the inclined surface 93 and the through hole 92 is a pyramid shape cut when the through hole 92 is composed of a square, and the through hole 92 is formed into a circular shape. In this case, the cone is in a cut shape, and according to the shape of the through hole 92, it may be configured in a cut barrel corresponding to it. The cut pyramid or cone is configured to protrude from the lower surface of the reflector 90 in the direction of the UV-B LED 80, and the end of the pyramid or cone is approached and the UV-B LED 80 is cut. The pyramid or cone, that is, the inclined surface 93 and the penetration hole 92 minimize interference of light emitted from the UV-B LED 80.

Since the wide angle of UV-B light emitted from the UV-B LED 80 is 120°, the inclined angle of the inclined surface 93 is 115 to 125°, preferably 120°. When the inclination angle of the inclined surface 93 is 115° or less, a part of the UV-B emitted from the UV-B LED 80 is reflected by collision with the inclined surface 93, and the wide angle of UV-B is reduced to irradiate UV-B. The area is reduced, and when the inclination angle of the inclined surface 93 is 125 ° or more, the wide angle of UV-B is not reduced, but the portion of the reflector 90 where the thickness is reduced increases, so that the reflector with the inclined surface 93 ( 90) is lowered. The size of the UV-B penetration hole 92 and the inclination angle of the inclined surface 93 are such that the maximum intensity of the reflector 90 can be maintained while maximally accepting UV-B emitted from the UV-B LED 80. it is composed

The flange 94 is composed of a flat surface that protrudes horizontally and integrally around the entire lower edge of the vertical portion 91 in an outer quadrangle. That is, the flange 84 is formed in a band shape extending in a radial direction from the portion where the vertical portion 91 formed at the edge of the bottom surface of the reflector 90 is located, so that the reflector 90 is formed through the through hole 51 of the diffusion cover 50. ), the reflector 90 is no longer inserted into the interior of the diffusion cover 50.

Since the outer surface size of the vertical portion 91 is inserted into the through hole 51 of the diffusion cover 50 while being closely attached to the flange 84, the size of the flange 84 is larger than the size of the through hole 51 of the diffusion cover 50. While the flange 84 is configured not to be inserted into the through hole 51 of the diffusion cover 50, the upper part of the inclined surface 93 and the lower surface of the UV-B LED 80 do not come into contact.

The flange 94 is formed on the edge of the lower four sides of the vertical portion 91 of the short square cylinder in the case of a rectangular plate shape of the UV-B LED substrate 70, and is formed on the outer circumference of a short cylindrical shape in the case of a disk shape. When the reflector 90 is inserted into the diffusion cover 50, the top surface of the flange 94 adheres to the bottom surface of the diffusion plate 50, that is, the outer surface of the diffusion plate 50. The vertical portion 91 protrudes upward from the circumference adjacent to the edge of the bottom surface of the reflector 90, is fastened to the diffusion cover 50, embraces the inclined surface 93 inside, and is configured in a closed band shape.

The diffusion cover 50 and the reflector 90 are fastened to each other by a one-touch fastening means (not shown) formed of a previously known coupling protrusion (not shown) and coupling groove (not shown). The one-touch fastening means is configured on the inner surface of the diffusion cover 50 and the outer surface of the reflector 90, and the coupling protrusion protrudes in a hemispherical or triangular shape on the inner surface of the diffusion cover 50 or the outer surface of the reflector 90, and the coupling groove is the reflector It is configured at a position corresponding to the outer surface of 90 or the inner surface of the diffusion cover 50 as a hemispherical or triangular groove. When the coupling protrusion is formed on the inner surface of the diffusion cover 50, the coupling groove is formed on the outer surface of the reflector 90, and when the coupling groove is formed on the inner surface of the diffusion cover 50, the coupling protrusion is formed on the outer surface of the reflector 90. do.

On the outer surface of the reflector 90, a one-touch fastening means (not shown) made of a known coupling protrusion (not shown) is configured, and by this fastening means (not shown), the diffusion cover 50 is a light diffusion cover ( 50) is concluded. The coupling between the diffusion cover 50 and the vertical portion 91 according to the contact surface between the diffusion cover 50 and the reflector 90, that is, the contact surface between the diffusion cover 50 and the vertical portion 91. The installation position of the protrusion and coupling groove is changed. The vertical portion 91 is bent upward around the edge of the bottom surface of the reflector 90 and is inserted into the through hole 51 when the reflector 90 is placed on the diffusion cover 50 .

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 detects the CLK signal of the external wall switch and applies the signal to the switch control unit (SW1/SW2 Control) so that the MOSFET transistor (field effect transistor (FET) : field effect transistor, Q1] and determining the on/off of the transistor Q2, turning on LED1 and LED2 by the number of repetitions of the on/off of the switch, and turning on LED3 Individual lighting is optional.

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 wall 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). ) controls the drive by determining the switches SW1 and SW2. 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 wall 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 wall 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 wall 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.
