Abstract
Description
Technology Field
[0001] The present invention relates to a weatherproof SMD LED module and a wall light with a replaceable LED module using the same. More specifically, the invention relates to a weatherproof SMD LED module that has excellent weatherproofing capabilities even when installed as an upward light, and a wall light with a replaceable LED module using the same, which allows for the LED module to be quickly replaced by separating it from the fixture when the LED module of the wall light fails. Background Technology
[0003] Wall lights are installed on the exterior of buildings to serve as landscape lighting, illuminating blind spots, aiding safe pedestrian movement at night, and enhancing security. Wall lights are also installed at parking lot entrances.
[0005] As wall lights are primarily used outdoors, it is of utmost importance to have strong rain and moisture resistance against snow and rain. This is because wall lights with poor rain and moisture resistance have a very short lifespan due to LED module failure.
[0007] Therefore, conventional wall lights have primarily used COB LEDs (Chip On Board LEDs) rather than SMD LEDs as the light source for their LED modules. A COB LED consists of multiple small LED chips attached to a single substrate and connected by a single common electrode (anode / cathode). Wall lights using COB LEDs are designed with a sealed front structure to ensure the fixture also features rain and moisture resistance; after assembling the fixture and COB LEDs, the entire sealed fixture is often treated with molding or other methods to provide rain and moisture protection. However, because COB LEDs densely pack a large number of chips into a small area, they generate very high heat per unit area. Since wall lights using these LEDs are sealed and molded for rain and moisture protection, heat dissipation is difficult, leading to problems such as the LED chips burning out or a drastic reduction in lifespan. In particular, because COB LED wall lights struggle to dissipate heat properly, the light often starts bright but dims over time (luminous flux reduction) or flickers. Therefore, wall lights using COB LEDs are sometimes manufactured as integrated units where the fixture and LED module are combined into a single unit. This is because the integrated design is the most advantageous structure for dissipating this heat.
[0009] Meanwhile, enclosed or integrated wall fixtures using COB LEDs present a problem in that the entire fixture must be replaced when the COB LED fails. This is because it is very difficult to separate and replace only the COB LED in enclosed or integrated wall fixtures, and in some cases, it is easy to damage the entire wall fixture. Therefore, in reality, when a COB LED fails, the entire wall fixture is replaced. However, this significantly increases the cost of replacing the wall fixture.
[0011] Registered Patent Publication No. 10-2160057 discloses a heat dissipation, moisture-proof, and waterproof LED module. The heat dissipation, moisture-proof, and waterproof LED module according to Registered Patent Publication No. 10-2160057 comprises: a heat dissipation part including a mounting surface formed on one side, a rim protruding along the perimeter of the mounting surface, and a plurality of main heat dissipation fins protruding on the other side; a heat conduction part made of a material having a thermal conductivity at least higher than that of the heat dissipation part and mounted on the mounting surface of the heat dissipation part such that the other side contacts the mounting surface of the heat dissipation part; a circuit board mounted on the mounting surface such that the other side contacts the heat conduction part mounted on the mounting surface of the heat dissipation part, and includes a plurality of LED elements arranged at regular intervals on one side of the one side and a connector provided on one side of the one side; and a cover part coupled to the mounting surface of the heat dissipation part and configured to cover the circuit board. According to Registered Patent Publication No. 10-2160057, a heat dissipation, moisture-proof, and waterproof LED module includes a sealing part configured to fill the space between the edge of the heat dissipation part and the heat conduction part and the circuit board for moisture-proofing. The sealing part is provided between the edge of the heat conduction part and the circuit board and the heat dissipation part to prevent shaking of the heat conduction part and the circuit board, and to prevent rainwater or dust entering between the cover part and the edge from penetrating into the circuit board. In the heat dissipation, moisture-proof, and waterproof LED module according to Registered Patent Publication No. 10-2160057, the sealing part and the cover part are inserted into the edge of the heat dissipation part and fastened with screws to the bottom of the mounting surface of the heat dissipation part.
[0013] However, if an LED module with this structure is used as is in a wall light, the following problems arise.
[0015] When an LED module is installed to enable upward lighting on a wall light, rainwater or moisture mainly enters through the gap between the cover and the frame, screw holes, or the power line inlet connected to the connector.
[0017] As described in Patent Publication No. 10-2160057, when a rim is formed on the outer edge of the mounting surface facing upward, and a sealing part, a heat conduction part, a circuit board, and a cover part are inserted into the rim and assembled by screws, and this is used as an upward-facing wall light, moisture or rainwater mainly enters through the gap between the rim and the cover part and through the screw holes. In Patent Publication No. 10-2160057, only a connector is attached to the circuit board and power lead wires are not illustrated, but moisture or rainwater penetrates into the interior along the power wires connected to this connector. In particular, according to Patent Publication No. 10-2160057, even if the cover part is strongly assembled to the mounting surface by screws, the gap between the rim of the heat dissipation part, the cover part, and the edge of the sealing part is exposed upward, so if rainwater falls for a long time, the rainwater that penetrates through the gap accumulates on the bottom of the mounting surface. In addition, as described in Patent Publication No. 10-2160057, when a connector is attached to a circuit board and an LED power line is routed from this connector through a cover or the like, it is difficult to avoid the penetration of moisture and rainwater.
[0019] Therefore, the LED module disclosed in Patent Publication No. 10-2160057 is unsuitable for use as an LED module for wall lights, particularly for high-beam lights. Prior art literature
[0021] Registered Patent Publication No. 10-2160057 (Registration Date: September 21, 2020) The problem to be solved
[0022] The present invention is made to solve the problems of wall lights installed outdoors as described above. The first objective of the present invention is to provide a waterproof SMD LED module and an LED module replaceable wall light utilizing the same, which enhances the waterproof and moisture-proof functions by securing a structure that prevents water infiltration in the LED module itself, while simultaneously enhancing the replaceability of the LED module in the fixture so that the LED module can be quickly replaced while the fixture remains installed in the event of an LED module failure.
[0024] The second problem that the present invention aims to solve is to provide a rainproof SMD LED module capable of effectively blocking water penetration into the LED substrate even when the LED module is used for high beams, and a wall light with a replaceable LED module using the same. means of solving the problem
[0026] The above-described objectives of the present invention can be achieved by configuring a weatherproof SMD LED module comprising: an aluminum SMD LED substrate having a plurality of SMD LEDs mounted on an aluminum substrate; an aluminum heat sink having the aluminum SMD LED substrate mounted on the center of the upper surface of a plate-shaped body and a plurality of heat dissipation fins formed on the lower surface; a sealing pad having an opening provided to accommodate the aluminum SMD LED substrate in the center and having an outer shape and size capable of covering the entire planar area of the aluminum heat sink, and stacked around the aluminum SMD LED substrate on the aluminum heat sink; and a heat sink housing lens cover having four side walls formed downwardly to surround the side of the main body of the aluminum heat sink and the side of the sealing pad, a plurality of light-diffusing lenses formed in the center that can be positioned directly above each SMD LED mounted on the aluminum SMD LED substrate, and screw-coupled to the aluminum heat sink while at least a portion of the upper part of the main body of the aluminum heat sink and the sealing pad are accommodated within the four side walls.
[0028] The problems of the present invention described above can be solved by configuring an LED module replaceable wall light comprising: a bracket fixed to a wall; an open-type light fixture cover that is detachably attached to the bracket from the rear by means of a screw, with both sides extending from the rear and the front protruding forward from the rear, and having an open direction in which the weatherproof SMD LED module is installed, either upward or downward; a light fixture body that is detachably assembled by means of a screw while inserted into the light fixture cover, having a heat dissipation fin receiving space provided on the upper or lower surface to accommodate a heat dissipation fin formed on the aluminum heat sink of the weatherproof SMD LED module; and the weatherproof SMD LED module that is detachably assembled to the light fixture body by means of a screw while the heat dissipation fin is inserted into the heat dissipation fin receiving space of the light fixture body.
[0030] The heat dissipation fin receiving space provided in the above-mentioned lighting fixture body is one or two, and the light emission direction of the rainproof SMD LED module coupled to the heat dissipation fin receiving space may be at least one of upward or downward. Effects of the invention
[0032] According to the present invention, in an upward wall light, when a lens cover housing a heat sink of a rainproof SMD LED module and an aluminum heat sink are assembled, the side wall of the lens cover housing the heat sink wraps around the main body of the aluminum heat sink like the eaves of a building roof, thereby blocking rainwater from penetrating into the aluminum SMD LED substrate provided on the upper surface of the aluminum heat sink. Therefore, in the rainproof SMD LED module unit rather than the wall light fixture, the rainwater penetration prevention function provided by the lens cover housing the heat sink is further reinforced in addition to the rainproof / moistureproof function provided by the sealing pad. Accordingly, particularly in an upward wall light, it is possible to prevent rainwater penetration into the rainproof SMD LED module, thereby preventing failure of the rainproof SMD LED module.
[0034] In addition, according to the present invention, by configuring an LED module replaceable wall light with an open fixture cover that is open upward or downward, a fixture body that is coupled to the open fixture cover by screws alone, and a weatherproof SMD LED module that is assembled to the fixture body so as to be oriented upward or downward and fastened by screws, the weatherproof SMD LED module can be replaced without the need to replace the fixture cover or fixture body from the bracket when the weatherproof SMD LED module fails; instead, the faulty weatherproof SMD LED module can be removed from the fixture body, the wiring is disconnected, the wiring of a new weatherproof SMD LED module is reconnected, and the module is fastened to the fixture body by screws. This allows for a significant reduction in replacement costs when the wall light fails. Brief explanation of the drawing

[0037] Hereinafter, specific embodiments of a rainproof SMD LED module according to the present invention and an LED module replaceable wall light using the same will be described in detail with reference to the attached drawings.
[0039] FIGS. 1 to 7 show the structure of a rainproof SMD LED module according to one embodiment of the present invention.
[0041] As illustrated in FIGS. 1 to 7, the waterproof SMD LED module (101) according to the present invention includes an aluminum SMD LED substrate (1) on which a plurality of SMD LEDs (5) are mounted. When making the SMD LED substrate (1) according to the present invention, the LEDs (5) are mounted as SMD (Surface Mounting Device) on the aluminum substrate (3), so the heat generated from the LEDs (5) is directly transferred to the aluminum heat sink (17) and released into the air. Therefore, there is no need to provide a separate heat conduction part to transfer heat between the SMD LED substrate (1) and the heat sink (17). A plurality of position alignment holes (7a, 7b) may be formed in the aluminum SMD LED substrate (1) to facilitate position adjustment when combined with a heat sink housing lens cover (53).
[0043] The above aluminum SMD LED substrate (1) is directly attached to the main body (19) of the aluminum heat sink (17). The aluminum heat sink (17) has the aluminum SMD LED substrate (1) mounted on the center of the upper surface of the plate-shaped main body (19), and a plurality of heat dissipation fins (21) are formed on the lower surface. A plurality of tabs (23) are formed on the main body (19) of the aluminum heat sink (17) to screw-couple a heat sink housing lens cover (29). In addition, a plurality of screw holes (25) are formed on the main body (19) of the aluminum heat sink (17) to connect a rainproof SMD LED module (101) according to the present invention to a lighting fixture (105a~105c). Additionally, a power line hole (27) is formed in the center of the main body (19) of the aluminum heat sink (17), and after a power line (63) is introduced through this power line hole (27), the power terminal (65) of the power line (63) is connected to an aluminum SMD LED substrate (1) attached to the surface of the main body (19).
[0045] After the power line (63) is introduced into the above aluminum heat sink (17), the power line hole (27) can be molded with silicone resin or the like.
[0047] As illustrated in FIG. 7, after the power line (63) is inserted into the aluminum heat sink (17) and molded, a sealing plate (55) for fixing the molding part can be attached around the power line (63). The sealing plate (55) may have a power line hole (27) into which the power line (63) is inserted and a screw hole (59) for fixing the sealing plate (55) to the lower surface of the main body (19) of the aluminum heat sink (17). A tap (not shown in the drawing) may be formed on the lower surface of the main body (19) of the aluminum heat sink (17), and the sealing plate (55) may be fixed to the lower surface of the aluminum heat sink (17) by means of a sealing plate fastening screw (61). The power line (63) may further be equipped with a noise filter (67) capable of removing noise from the power supplied to the SMD LED (5). FIG. 2 shows an aluminum SMD LED substrate (1), an aluminum heat sink (17), and a power line (63) assembled in this way, as well as a sealing pad (9) and a heat sink housing lens cover (29) disassembled from the heat sink (17).
[0049] As shown in FIGS. 2 and 3, a sealing pad (9) and a heat sink housing lens cover (29) are further combined on the aluminum SMD LED substrate (1) attached to the aluminum heat sink (17).
[0051] The sealing pad is a plate-shaped pad with high elasticity and flexibility, such as a rubber pad, silicone pad, or urethane pad. The sealing pad (9) is provided with an opening (11) capable of accommodating the aluminum SMD LED substrate (1) in its inner center. The outer size of the sealing pad (9) has a shape and size capable of covering the entire planar area of the aluminum heat sink (17) and is laminated around the aluminum SMD LED substrate (1) on the aluminum heat sink (17). The sealing pad (9) has a screw hole (13) for a heat sink fastening screw (53) and a screw hole (15) for a light fixture fastening screw (see reference numerals 103a and 103b in FIG. 8). As shown in FIG. 3, the screw hole may be a non-penetrating screw hole (15a) with a thin film (15b) remaining on the bottom. With this structure, when fastening the heat sink fastening screw (53), the thin film (15b) adheres closely to the screw, thereby enhancing the rainproof and moistureproof functions.
[0053] The aluminum SMD LED substrate (1) and the sealing pad (9) laminated on the aluminum heat sink (17) are sealed by a heat sink housing lens cover (29).
[0055] As illustrated in FIGS. 4 to 6, one of the features of the present invention is that the heat sink housing lens cover (29) is formed as a roof eave structure capable of effectively performing a rainproof function. To this end, the heat sink housing lens cover (29) according to the present invention has four side walls (31) formed downwardly to wrap around the side of the main body (19) of the aluminum heat sink (17) and the side of the sealing pad (9). Due to this structure, at least a portion of the sealing pad (9) and the upper part of the main body (19) of the aluminum heat sink (17) is received inside the four side walls (31) of the heat sink housing lens cover (29) and is screw-coupled to the aluminum heat sink (17).
[0057] As shown in FIG. 4, a cylindrical compression projection (45) or a circumferential compression projection (47) may be formed around the screw hole (33) on the lower surface of the heat sink housing lens cover (29) so that when the screw is fastened, the sealing pad (9) may be closely attached in the direction of the heat sink fastening screw (53) to which it is fastened. This prevents water or moisture from penetrating through the heat sink fastening screw (53). Additionally, on the lower surface of the heat sink housing lens cover (29), a substrate mounting groove (41) into which the aluminum SMD LED substrate (1) can be inserted and an LED receiving groove (39) into which an SMD LED mounted on the aluminum SMD LED substrate (1) can be inserted may be formed. When an aluminum SMD LED substrate (1) is received in the substrate mounting groove (41) and an SMD LED (5) is received in the LED receiving groove (39), the heat sink receiving lens cover (29) can be fastened to the aluminum heat sink (17) with a sealing pad (9) inserted therein so that strong compression is achieved. This allows for enhanced rainproof and moisture-proof functions.
[0059] As illustrated in FIGS. 2 and 4, a plurality of position alignment holes (7a, 7b) are formed in the aluminum SMD LED substrate (1), and position alignment protrusions (51a, 51b) can be formed on the lower surface of the heat sink receiving lens cover (29) at the position where the aluminum SMD LED substrate (1) is seated in the substrate mounting groove (41) and the SMD LED (5) is seated in the LED receiving groove (39). Through this, when assembling the heat sink receiving lens cover (29) to the aluminum heat sink (17), the aluminum SMD LED substrate (1) is always accurately seated in the substrate mounting groove (41) and the SMD LED (5) is accurately seated in the LED receiving groove (39), so that the sealing pad (9) can be assembled in a strongly compressed state.
[0061] FIG. 5 is an assembly perspective view of a rainproof SMD LED module according to one embodiment of the present invention, and FIG. 6 is a cross-sectional view along the B-' cutting line of FIG. 5.
[0063] As illustrated in FIGS. 5 and 6, according to the present invention having the above-described configuration, when the heat sink housing lens cover (29) and the aluminum heat sink (17) are assembled, the side wall (31) of the heat sink housing lens cover (29) wraps around the main body of the aluminum heat sink like the eaves of a building roof, effectively blocking rainwater from penetrating into the aluminum SMD LED substrate (1) provided on the upper surface of the aluminum heat sink (17). Therefore, in a unit of a rainproof SMD LED module (101) rather than a wall light fixture, in addition to the rainproof / moistureproof function provided by the sealing pad (9), the rainwater penetration prevention function provided by the heat sink housing lens cover (29) is further reinforced, so that, especially in an upward wall light installed outdoors, rainwater penetration into the LED module can be prevented, thereby preventing the LED module from failing.
[0065] A plurality of light-diffusing lenses (37) are formed in the center of the heat sink housing type lens cover (29) according to the present invention, which can be placed directly above each SMD LED (5) mounted on the aluminum SMD LED substrate (1). A screw hole (33) for a heat sink fastening screw (53) and a screw hole (35) for a light fixture fastening screw (see reference numerals 103a and 103b in FIG. 8) are also formed in the heat sink housing type lens cover (29).
[0067] FIGS. 8 to 13 show various embodiments of an LED module replaceable wall light equipped with a waterproof SMD LED module.
[0069] FIGS. 8 and 9 show an LED module replaceable wall light manufactured to illuminate the upper and lower sides of a wall surface, wherein two heat dissipation fin receiving spaces (107a) are formed in a single light fixture body (105a) and open toward the upper and lower sides, and a rainproof SMD LED module (101) is mounted in each heat dissipation fin receiving space (107a). In the embodiment illustrated in FIGS. 8 and 9, the light fixture cover (115a) is an open light fixture cover with both the upper and lower sides open.
[0071] FIGS. 10 and 11 show an LED module replaceable wall light manufactured to illuminate the lower side of a wall surface, wherein a heat dissipation fin receiving space (107b) having an opening shape is formed in a single light fixture body (105b), and the rainproof SMD LED module (101) is mounted in the heat dissipation fin receiving space (107b). In the embodiment illustrated in FIGS. 10 and 11, the light fixture cover (115b) is an open type light fixture cover that is open only at the bottom.
[0073] FIGS. 12 and 13 show an LED module replaceable wall light manufactured to illuminate the upper and lower sides of a wall surface, wherein a heat dissipation fin receiving space (107c, 107d) having an opening shape is formed in each of the two light fixture bodies (105c, 105d), and the rainproof SMD LED module (101) is mounted in each of the heat dissipation fin receiving spaces (107c, 107d).
[0075] As illustrated in FIGS. 8 to 13, the LED module replaceable wall light according to the present invention includes a bracket (131a, 131b, 131c) fixed to a wall and an open light fixture cover (115a, 115b, 115c) screw-fastened to the bracket (131a, 131b, 131c). The above-mentioned open-type light fixture cover (115a, 115b, 115c) is detachable from the rear surface (117a, 117b, 117c) by means of a bracket fastening screw (129a, 129b, 129c) to the bracket (131a, 131b, 131c), and the two side surfaces (119a, 119b, 119c) and the front surface (121a, 121b, 121c) extending from the rear surface (117a, 117b, 117c) protrude forward from the rear surface (117a, 117b, 117c), and the direction in which a rainproof SMD LED module (101) is installed is open, either upward or downward. A light fixture body (105a~105d) having a heat dissipation fin receiving space (107a~107d) is screw-fastened inside the above-mentioned open light fixture cover (115a, 115b, 115c), and the above-mentioned rainproof SMD LED module (101) is installed facing upward or downward in the heat dissipation fin receiving space (107a~107d) of the light fixture body (105a~105d). In the main body of the light fixture (105a~105d), a heat dissipation fin receiving space (107a~107d) capable of receiving a heat dissipation fin (21) formed on the lower surface of the aluminum heat sink (17) of the waterproof SMD LED module (101) is provided on the upper or lower surface, or is provided through the upper and lower surfaces, and is assembled so as to be detachably attached by screws (103a, 103b, 103c) while inserted inside the light fixture cover (115a, 115b, 115c). The waterproof SMD LED module (101) is assembled so as to be detachably attached by screws to the main body of the light fixture (105a~105d) while the heat dissipation fin (21) is inserted into the heat dissipation fin receiving space (107a~107d) of the main body of the light fixture (105a~105d).
