Description

Technical Field

[0001] The utility model relates to a lighting device with a visible light disinfection function, which can provide a disinfection function by using visible disinfection light harmless to human body in indoor space in addition to the traditional lighting function. Background Art

[0002] Generally, lighting lamps are used to illuminate dark places indoors and outdoors. The most commonly used lighting lamps such as fluorescent lamps are lighting equipment that is coated with fluorescent substances in a vacuum glass tube, and mercury and argon are added to convert ultraviolet rays generated by mercury discharge into visible light. However, compared with incandescent lamps, fluorescent lamps consume less electricity, but have a shorter life and a shorter replacement cycle. Fluorescent lamps require a stabilizer to provide high voltage for initial discharge. Compared with the power consumption and life of fluorescent lamps, LEDs (light emitting diodes) emphasize long life, low power consumption, compact size and environmentally friendly manufacturing, and are becoming the main lighting lamps.

[0003] Although LED lamps are expensive to manufacture, installation costs can be expected to be lower as the scope of application expands and mass production begins. In particular, LEDs generally have a lifespan of 100,000 hours, so initial installation costs may be higher, but electricity savings and reduced operating costs are expected.

[0004] On the other hand, according to their luminous properties, LEDs can be divided into infrared LEDs, visible light LEDs, and ultraviolet LEDs. Among them, ultraviolet (UV) LEDs have been proven to eliminate bacteria containing DNA or RNA, and are widely used as a disinfection method in various fields, and are also proposed for indoor purification combined with lighting. However, traditionally, the use of ultraviolet LEDs as a disinfection method for indoor purification has been adopted. Although ultraviolet rays can eliminate bacteria containing DNA or RNA, direct irradiation to the human body may be harmful to the human body. Utility Model Content

[0085] The following describes a lighting device with visible light sterilization function in a preferred embodiment of the present invention according to the aforementioned drawings.

[0086] According to an embodiment of the utility model, the lighting device is intended to provide lighting light for a specific area of ​​an indoor space according to the needs of the user, and selectively or simultaneously provide sterilization light for the indoor space. Figure 1 and Figure 3 As shown, it mainly includes a body part (10), a cover part (20), a converter part (30) and a control part (40).

[0087] The body part (10) is composed of a bottom and sides surrounding it, and its upper part is open, providing a space for the main functions of the lighting device, accommodating a lighting module (300), a disinfection module (400), a light diffusion part (500), a converter part (30) and a control part (40).

[0088] The cover part (20) is an outer shape surrounding the side and rear of the body part (10), and its function is to close the open upper part of the body part (10).

[0089] When the above-mentioned body part (10) and cover part (20) are combined, the open upper part of the body part (10) is closed by the inner surface of the cover part (20) to form a closed inner space.

[0090] Related to this, Figure 2 As shown, the body part (10) specifically includes a frame (100) and a support member (200).

[0091] First, the function of the frame (100) is to form the outer frame of the body part (10).

[0092] The frame (100) includes a linear outer frame (110) corresponding to a corner portion of a peripheral frame and a ┐-shaped corner connecting component (120) corresponding to the corner portion.

[0093] The frame (100) moves in parallel in the up-down and left-right directions through two pairs of outer frames (110), so that the adjacent ends of the two pairs of outer frames (110) contact each other. Then, the ends of the contacting outer frames (110) are connected to each other, thereby forming a quadrilateral frame-shaped external structure.

[0094] The outer frame (110) is formed by an integrated structure of a first frame (110a), a second frame (110b) and a connecting frame (110c).

[0095] Here, the first frame (110a) has an inner space with an open side. The second frame (110b) has a downward protrusion (212) on its upper surface, and the protrusion can slide in the left and right directions when inserted into a sliding groove (111) and one end of the protrusion is vertically extended upward. At this time, the connection frame (110c) is horizontally connected between the first frame (110a) and the second frame (110b), and the whole forms an integrated structure.

[0096] Here, the first frame (110a) has an inner space with an open side. The second frame (110b) has a downward protrusion (212) on its upper surface, and the protrusion can slide in the left and right directions when inserted into a sliding groove (111) and one end of the protrusion is vertically extended upward. At this time, the connection frame (110c) is horizontally connected between the first frame (110a) and the second frame (110b), and the whole forms an integrated structure.

[0097] A corner connecting component (120) vertically connects a pair of outer frames (110) to form a corner.

[0098] In addition, the corner connecting component (120) is formed with a protruding insertion piece (121) on the connecting surface with the outer frame (110) for inserting into the sliding groove (110) of the second frame (110b), and a protruding mounting piece (122) for mounting on the upper surface of the first frame (110a).

[0099] At this time, the corner connecting component (120) is preferably formed with the same width and height as the outer frame (110) so as to be interlocked with the pair of outer frames (110).

[0100] In addition, the corner connecting component (120) can form a receiving space at its lower part that communicates with the internal space of the first frame (110a), and wires connected to the circuit board of the lighting module (300) can be introduced into the receiving space, wherein part of the wires can be accommodated and the rest of the wires can be exposed to the outside.

[0101] First, a support member (200) is coupled to the inner side of the frame of the frame (100) to support the corner portion of each frame.

[0102] The support member (200) can be formed by interconnecting a plurality of connection units (210), a heat dissipation unit (220) and a central connecting component (230), and can form a cross-shaped support structure.

[0103] The connection unit (210) serves to connect the heat dissipation unit (220) and the central connecting component (230) to the frame (100).

[0104] One end of the connection unit (210) can be installed perpendicularly to the length direction of each corner at a position vertically offset from the lighting module (300) on the inner corners of the frame (100) in the up-down and left-right directions.

[0105] In addition, the connection unit (210) is as follows Figure 5 As shown, a downward protrusion (212) for mounting on a frame (100) may be formed on one side and an insertion protrusion (211) for connecting with a heat dissipation unit (220) may be formed on the other side.

[0106] At this time, the downward protrusion (212) may be in a shape protruding from the bottom surface of the connection unit (210) adjacent to the outer frame (110).

[0107] Furthermore, the insertion protrusion (211) can extend horizontally from the other end of the connection unit (210) toward the inner center of the frame (100), and preferably has the same width as the circuit board of the sterilization module (400) and extends a certain length to the outside so as to be inserted into the insertion groove (221c) of the heat dissipation unit (220), which is also called the disinfection module.

[0108] Here, the center of the upper surface of the connection unit (210) is as follows Figure 5 As shown, a screw hole (214) for fixing the connection unit (210) to the second frame (110b) may be provided.

[0109] The heat dissipation unit (220) is used to dissipate the heat released from the disinfection module (400).

[0110] Here, the upper surface of the heat dissipation unit (220) may be provided with an embedding groove (221a) corresponding to the outer peripheral surface of the diffusion lens (600), a connection groove (221b) vertically extending downward from the embedding groove (221a), and an insertion groove (221c) connected to the connection groove (221b) and corresponding to the shape of the substrate of the disinfection module (400).

[0111] Specifically, refer to Figure 6 The embedding groove (221a) has a first region and a second region. The first region gradually narrows in cross section with a certain slope from top to bottom, forming a first slope. The second region has a second slope with a slope opposite to the first slope, and settles to a certain depth from the inside to the inside. The shape of the insertion groove (224c) is the same as the width and height of the substrate of the disinfection module (400), and has a protruding hook at the top.

[0112] At this time, the lateral length of the insertion groove (224c) is preferably the total length of the base plate of the disinfection module (400), the insertion protrusion (211) of the connection unit (210) and the coupling end (231) of the central connecting component (230).

[0113] In this case, the disinfection module (400) is first inserted into the insertion groove (224c) so that it is located at the center, and then the insertion protrusion (211) and the coupling end (231) are respectively inserted at both ends so that they contact each other. Figure 4 As shown, the connection unit (210), the heat dissipation unit (220) and the central connecting component (230) are all integrated together.

[0114] The heat dissipation unit (220) may be provided in a number corresponding to the connection unit (210), and one end may be inserted corresponding to the insertion protrusion (211).

[0115] Here, the bottom of the heat dissipation unit (220) may be provided with a plurality of heat dissipation fins (225) arranged at regular intervals in a vertical direction in a housing shape.

[0116] At this time, the heat dissipation unit (220) may be manufactured by a casting or die-casting method of aluminum so that the heat dissipation fins (225) have a sawtooth shape.

[0117] In addition, both sides of the upper portion of the heat dissipation unit (220) may be provided with protruding outward guide rails (223).

[0118] A central connecting component (230) is located between two pairs of adjacent heat dissipation units (220) so that each pair is parallelly connected.

[0119] Here, the central connecting component (230) is as follows Figure 7 As shown, it includes a case (Case) (233), a through-hole (Through-hole) (232) and a protrusion (protrusion) (231).

[0120] The housing (Case) (233) has an open bottom and an internal space, a through-hole (232) is formed on each side of the housing (Case) (233) to introduce a cable connected to the substrate of the sterilization module (400), and a protrusion (231) protrudes a certain length upward and leftward from the top of the housing (Case) (233) and is inserted into the insertion groove (221c) of the heat dissipation unit (220) and connected.

[0121] The lighting module (300) is used to emit light to illuminate a specific area of ​​the indoor space, and determines whether to emit light according to the lighting mode selection of the user.

[0122] Here, a lighting module (300) is a substrate on which a plurality of LEDs (301) emitting a specific color temperature (for example, daylight color of 5700K) are mounted, and is installed at an inner corner of a frame (100).

[0123] The disinfection module (400) is used to emit ultraviolet rays for disinfecting the indoor space, and determines whether to emit light according to the user's lighting mode selection.

[0124] Here, the disinfection module (400) is a substrate on which a plurality of LEDs (401) emitting ultraviolet light and visible light boundary wavelengths (eg, 405 nm) are mounted, and is inserted into the interior of a support member (200).

[0125] When the disinfection LED (401) emits light and irradiates for more than a certain period of time, it can kill harmful bacteria such as Escherichia coli, Staphylococcus aureus, MRSA, Pneumococcus, Staphylococcus, and RNA series viruses such as COVID-19, MERS, and SARS.

[0126] At this time, the disinfection module (400) can be connected to the insertion groove (221c) of the heat dissipation unit (220) arranged in a cross shape with the central connecting component (230) as the center. When working in the disinfection operation mode (Ms), multiple disinfection LEDs (401) emit light at the same time, and the disinfection light emitted overlaps in a cross shape, thereby achieving the maximum disinfection effect instantly.

[0127] The aforementioned lighting module (300) and disinfection module (400) can both be configured in the form of a plurality of LED elements mounted on the upper surface of a printed circuit board (PCB) of a certain size.

[0128] At this time, the board length of the lighting module (300) should be relatively short and smaller than the width of the first frame (110a), and the board length of the sterilization module (400) should be relatively short and smaller than the horizontal length of the insertion groove (221c) of the heat dissipation unit (220).

[0129] A light diffusion part (500) is installed between a frame part (100) and a support member (200) to uniformly emit light irradiated from the side to the front.

[0130] One side of the light diffusion part (500) is adjacent to the light emitting surface of the lighting module (300). When the lighting LED (301) emits light, it can reflect, diffuse and refract the light, thereby evenly emitting the light to the front.

[0131] Here, both sides of the light diffusion part (500) are respectively inserted into the inner space of the first frame (110a) and the inside of the guide rail (223) which are parallel to each other.

[0132] In addition, the light diffusion part (500) may be formed as Fig. 9As shown in , a reflector (510), a light guide plate (520), a reflective sheet (530) and a diffuser (540) are stacked in sequence, and the emitting surface of the diffuser (540) can face forward.

[0133] At this time, the reflector (510) and reflective sheet (530) corresponding to the light reflection layer are preferably made of 6061 alumina material and RS / PET material with high light reflectivity. The light guide plate (520) corresponding to the light refraction layer is preferably made of PMMA (Poly methyl methacrylate) or PC (PolyCarbonate) material with high light transmittance. The diffusion plate (540) corresponding to the light diffusion layer is preferably made of PS (Polystyrene) material with high light diffusion properties.

[0134] The function of the diffusion lens (600) is to diffuse the irradiated light to the outside when the disinfection LED (401) emits light.

[0135] A diffusion lens (600) may be installed in front of the support member (200) at a position vertically corresponding to the light emitting surface of the disinfection module (400).

[0136] Specifically, the diffusion lens (600) can be Figure 8 As shown in FIG. 1 , the outer inclined surface (601) gradually narrows from top to bottom, a bottom groove (602) with a certain depth from the bottom to the inside, and a side protrusion (603) protruding in an inclined direction opposite to the outer inclined surface (601)

[0137] Here, the diffusion lens (600) is inserted into the embedding groove (221a) of the heat dissipation unit (220). To this end, the outer inclined surface (601) and the side protrusion (603) can have the same slope as the inclined surfaces of the first area and the second area in the embedding groove (221a) of the heat dissipation unit (220).

[0138] At this time, the diffusion lens (600) is preferably made of PMA (Poly methyl acrylate) material having high light diffusivity and high light transmittance.

[0139] The converter part (30) receives external AC power input and converts it into a preset DC voltage output for each LED of the lighting module (300) and the disinfection module (400).

[0140] A control part (40) controls a converter part (30) to drive an LED of a lighting module (300) or a disinfection module (400) according to a driving command of a user.

[0141] The control part (40) may receive a selection instruction about the driving combination of the lighting module (300) and the disinfection module (400) from the user. In this case, according to the above selection instruction, the LEDs of the lighting module (300) or the disinfection module (400) corresponding to the selected lighting mode may be selectively or simultaneously driven, thereby controlling the converter part (30).

[0142] The plurality of lighting modes include a lighting operation mode (M1), a disinfection operation mode (Ms), and a simultaneous operation mode (Mb). The lighting operation mode (M1) is a mode for driving only the lighting module (300), the disinfection operation mode (Ms) is a mode for driving only the disinfection module (400), and the simultaneous operation mode (Mb) is a mode for driving both the lighting module (300) and the disinfection module (400).

[0143] For example, it is assumed that two lighting modules (300) are respectively installed in the internal space of the first frame (110a) of the left and right outer frames (110), and four disinfection modules (400) are respectively installed on the heat dissipation unit (220) on the upper, lower, left and right sides.

[0144] When operating in the lighting operation mode (M1), the area corresponding to the light diffusion part (500) of the lighting device (1) emits the main light color. When operating in the disinfection operation mode (Ms), the cross-shaped area corresponding to the support member (200) of the lighting device (1) emits purple, and the surrounding area emits blue.

[0145] When operating in the simultaneous operation mode (Mb), the light diffusion part (500) and the corresponding area of ​​the support member (200) emit white and purple light respectively.

[0146] According to the utility model, the LED for lighting and the LED for disinfection are separately arranged in different areas inside the machine body. Therefore, according to the position of the LED that lights up, the lighting mode currently in operation can be intuitively identified.

[0147] At this time, the converter part (30) and the control part (40) may be electrically connected to the wires connected to the respective circuit boards of the disinfection module (400) and the lighting module (300).

[0148] Therefore, if Figure 1 and Figure 7 As shown, it can be housed in a case (233) of a central connecting component (230), or housed in a specific position of a closed internal space due to the combination of a body part (10) and a cover part (20).

[0149] In addition, according to an embodiment of the present invention, the lighting device with visible light disinfection function may further include, in addition to the above-mentioned components, an installation member (700) for installing the downlight structure on the ceiling.

[0150] The installation member (700) utilizes the hole drilled on the ceiling panel (ceiling panel) of the building for installing the lighting device, that is, the installation hole (not shown). In this way, the lighting device (1) according to the utility model can be embedded installed as a downlight structure.

[0151] Installation member (700) such as Fig.10 and Fig.11 As shown, it is composed of a bracket (720) and a spring clip (740). The bracket (720) can be detachably connected to the outer surface of the cover part (20) combined with the body part (10).

[0152] Bent Ribs (724) that are bent vertically downward are provided on both sides of the bracket (720), and a central hole (726) is provided in the center of the top.
