The diffusion cover 50 is fastened to the frame 10 or the housing 20 and is configured in front of the lighting LED 40 to diffuse the light emitted from the lighting LED 40 and diffuse it to the outside. A penetrating through hole 51 through which the reflector 90 is inserted is configured. Since the lighting LED 40 has a small angle at which light is diffused unlike the discharge lamp, the diffusion cover 50 expands the lighting angle of the light of the lighting LED 40 to increase the illuminated area to obtain a more efficient lighting effect. do. In addition, the material of the diffusion cover 50 may be transparent glass, acrylic or polycarbonate to improve light transmittance, and a diffusion agent is formed therein. The diffusion cover 50 is composed of a plate shape corresponding to the shape of the space formed by the frame 10, and when the frame 10 is not formed, it is composed of a plate shape corresponding to the bottom shape of the housing 20. .

The reflector 90 is configured in front of the UV-B LED 80, is inserted into the through hole 51 of the diffusion cover 50, and is perpendicular to the flange 94 protruding from the lower circumference and around the flat edge. The vertical portion 91 composed of a closed band shape and the penetration hole 92 corresponding to the UV-B LED 80 and extending to the penetration hole 92 and the penetration hole 92, that is, the inclined surface configured to become wider from the top to the bottom ( 93). The reflector 90 is configured with a transparent hole 92 having a rectangular or circular shape so that UV-B light emitted from the UV-B LED 80 can pass through the lower surface.

The reflector 90 has a transmission hole 92 so that the UV-B light emitted from the UV-B LED 80 can pass through the lower surface. Since UV-B has very weak penetrating power, it cannot be transmitted if there is a medium or cover other than quartz in the middle, so if the penetration hole 51 of the diffusion cover 50 is completely exposed to transmit UV-B, the human Since hands can come into contact with the terminals of the UV-B LED 80 and people can get an electric shock due to negligence in use or installation, safety against electric shock is improved by the reflector 90.

In the reflector 90, the lower boundary between the inclined surface 93 extending to the transmission hole 92 and the inclined surface 93 extending to the adjacent transmission hole 92 is a band-shaped plane, that is, a belt surface 95, and the belt surface ( 95) is connected to the same plane as the flange 94. For example, the through hole 92 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 95 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 94. When the penetration holes 92 are composed of 6 pieces in 2 rows and 3 rows, the band surface 95 of the lower boundary where the inclined surface 93 meets is composed of a ╊╊-shaped surface, and the ╊╊ surface is in the same plane as the flange 94. connection is made up.

The penetration hole 92 is configured at a position corresponding to the UV-B LED 80 and is configured the same as the quantity of the UV-B LED 80, and the center of each penetration hole 92 is It is configured to substantially coincide with the center of the UV-B LED 80. It is effective that the cross section of the penetration hole 92 is identical to that of the plane of the UV-B LED 80. Since the plane of the UV-B LED 80 is rectangular, the cross section of the penetration hole 92 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. 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.

The controller (IC, 220) controls lighting of the lighting LED 40 and UV-B LED 80 or lighting of only the lighting LED 40 whenever the switch is turned ON/OFF. Only the UV-B LED 80 is controlled to light. SW1 of the controller (IC, 220) outputs a control signal of the lighting LED 40 to operate the MOSFET transistor Q1, and SW2 outputs a control signal of the UV-B LED 80 to operate the MOSFET transistor Q2 make it work 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 the lighting LED 40 and the UV-B light are determined by the number of repetitions of the on/off of the switch. The LED 80 is selectively lit.

When the lighting LED 40 and the UV-B LED 80 are turned on, they become indoor lighting and can induce vitamin D synthesis in the body even if indoor residents or patients do not expose themselves to sunlight outdoors, and the lighting LED 40 When only turned on, it becomes indoor lighting, and when only the UV-B LED 80 is turned on during the night life time, indoor residents or patients can induce vitamin D synthesis in the body even during sleep.

When only the MOSFET transistor Q1 is turned on, the lighting LED 40 emits light, and when only the MOSFET transistor Q2 is turned on, the UV-B LED 80 emits light, and the MOSFET transistor Q1 and the MOSFET transistor ( When Q2 is turned on at the same time, the lighting LED 40 and the UV-B LED 80 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 operating the MOSFET transistor in 200, the entire driving circuit 200 is operated so that the lighting LED 40 and the UV-B LED 80 emit light.

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 roughness of (80) 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.
