Summary of the Invention

Problems to be Solved by the Invention

[0004] However, there is room for improvement in the above-mentioned conventional technology. For example, in the above-mentioned conventional technology, the water discharged from the faucet device lands on the water receiving part that slopes downward toward the back side in the washbasin, and then flows into the groove part located on the back side of the water receiving part. Therefore, it may occur that the water after landing on the washbasin flows into the central part of the groove part and no water flows to the side end part side of the groove part. Thus, in the above-mentioned conventional technology, the flow of water after landing on the washbasin is not particularly considered, and there is room for improvement in the flow of water after landing on the washbasin.

[0005] An object of the disclosed embodiment is to provide a washbasin vanity in which the water after landing on the washbasin flows appropriately inside the washbasin.

Means for Solving the Problems

[0006] A washbasin vanity according to one embodiment includes a washbasin having a water receiving section and a faucet device disposed above the water receiving section, wherein the washbasin has a water receiving surface where water discharged from the spout of the faucet device falls, an inclined section that slopes upward toward the rear from the rear end of the water receiving section, a groove located in front of the water receiving section and recessed below the water receiving section, side walls provided at both ends of the groove and the water receiving section, and a drain for draining the water that flows into the groove, wherein at least a portion of the water that falls into the water receiving section flows toward the inclined section, and after colliding with the inclined section, it splits into one flow that flows toward one of the side walls along the inclined section and another flow that flows toward the other side wall, the first flow flows into the groove along the one side wall, and the other flow flows into the groove along the other side wall.

[0007] According to one embodiment of the washbasin vanity, the water flow towards the inclined section, that is, the water flow toward the front (rear) side (also called the "main stream"), after colliding with the inclined section, splits into one flow toward one side wall (e.g., the left side) (also called the "first flow") and another flow toward the other side wall (e.g., the right side) (also called the "second flow"). Each of the first flow and the second flow flows into the groove from their respective ends in the left-right direction. As a result, the washbasin vanity can guide the water that has landed in the water receiving section toward the side wall located at the left-right end of the inclined section, thus ensuring that the water flows into both the left and right ends of the groove. Therefore, the washbasin vanity allows the water to flow properly within the washbasin after it has landed in the washbasin.

[0008] For example, in a configuration like that described in Patent Document 1, the water discharged from the faucet device hits a water receiving section in the washbasin that slopes downward toward the back (front) and then flows into a groove located at the back (front) of the water receiving section. In such a configuration, water does not flow to the left and right ends of the groove, resulting in residual water remaining in the groove at the left and right ends, which leaves room for improvement in terms of ease of cleaning. Therefore, according to a washbasin vanity according to one embodiment, by having the above-described configuration, the water that hits the washbasin can be reliably allowed to flow to the left and right ends as well, and the water that hits the washbasin can flow properly inside the washbasin.

[0009] In a washbasin vanity according to one embodiment, the inclined portion has a rounded shape in plan view and protrudes further to the rear towards the center, and the first flow and the other flow flow along the rounded inclined portion and spread out to both ends of the groove.

[0010] According to one embodiment of the washbasin vanity, water can be guided along the inclined section to the left and right ends, making it possible to more reliably ensure that water flows into the left and right ends. Therefore, the washbasin vanity allows water to flow properly inside the washbasin after it has entered the basin.

[0011] In a washbasin vanity according to one embodiment, the water receiving portion is trapezoidal in shape with the groove side as the upper base when viewed from above, and the distance between the side walls decreases towards the front.

[0012] According to one embodiment of the washbasin vanity, the force of the main stream can be maintained and directed to the rear wall, allowing it to be guided to the left and right ends. Therefore, the washbasin vanity allows the water to flow properly inside the washbasin after it hits it.

[0013] In a washbasin vanity according to one embodiment, at least the water landing surface of the water receiving portion is flat in the front-to-back direction, or has a downward slope toward the rear.

[0014] According to one embodiment of the washbasin vanity, the reduction in the force of the water that hits the water receiving section is suppressed, a strong main flow can be guided toward the inclined section, and the first flow and the second flow can be spread over a wider area in the left-right direction. As a result, the washbasin vanity can guide the water to the edge of the groove more reliably, regardless of the width of the washbasin. Therefore, the washbasin vanity can ensure that the water flows properly inside the washbasin after it hits it.

[0015] In a washbasin vanity according to one embodiment, the water landing surface and the drain opening are positioned to overlap in the left-right direction, and the width of the water landing surface in the left-right direction is greater than the width of the drain opening in the left-right direction.

[0016] According to one embodiment of the washbasin vanity, the water that hits the basin does not go towards the inclined section but instead forms a film of water that goes directly towards the groove, which allows the first flow and the second flow to spread more easily to the left and right. Therefore, the washbasin vanity allows the water to flow properly inside the basin after it hits the basin. [Effects of the Invention]

[0017] According to one embodiment, water can flow properly inside the washbasin after it has entered the washbasin. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments and modification examples of the washbasin and washbasin vanity disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited by the embodiments and modification examples shown below.

[0020] <1. Embodiment> First, the washbasin vanity 1 according to the embodiment will be described below. In each drawing, the same components are denoted by the same reference numerals, and detailed descriptions thereof are appropriately omitted. As shown in FIG. 1, the washbasin vanity 1 includes a mirror cabinet 2 and a washbasin 3. The washbasin vanity 1 is installed, for example, along the wall surface of a structure. FIG. 1 is a schematic perspective view of the washbasin vanity according to the embodiment. In this specification, when using the washbasin vanity 1, the left - right direction, the up - down direction, and the front - back direction are defined as shown in FIG. 1 with reference to the user standing in front of the washbasin vanity 1.

[0021] Furthermore, the configuration of the washbasin 10 and other components of the vanity unit 1 is defined below using the front-to-back direction. In this specification, the direction away from the user in the vanity unit 1 is defined as "front," and the direction approaching (facing) the user in the vanity unit 1 is defined as "rear." For example, the direction away from the user from the center of the front-to-back direction of the washbasin 10 is defined as "front," and the direction approaching (facing) the user from the center of the front-to-back direction of the washbasin 10 is defined as "rear." In this way, in the configuration of the washbasin 10 and other components of the vanity unit 1, the front side corresponds to the rear side, and the rear side corresponds to the front side. That is, below, "rear" may be read as "front," "front" as "rear," "front" as "rear," and "rear" as "front."

[0022] Mirror cabinet 2 has a cabinet with multiple mirrors that can be opened and closed, located on the front (rear) side. A washbasin 3 is located below mirror cabinet 2.

[0023] The washbasin 3 comprises a cabinet 4, a washbasin 10, and a faucet device 20. The faucet device 20 is located at the lower end of the mirror cabinet 2. The faucet device 20 discharges water from its spout. The faucet device 20 is located in the center of the washbasin vanity 1 in the left-right direction. The cabinet 4 is located at the lower end of the washbasin vanity 1. The cabinet 4 has multiple drawers. The cabinet 4 supports the washbasin 10. The washbasin 10 is located at the upper end of the cabinet 4.

[0024] As shown in Figure 2, the washbasin 10 comprises a bowl portion 30, a counter portion 60, and a drain plug 70. Figure 2 is a schematic perspective view of the washbasin according to the embodiment. For example, in the washbasin 10, the bowl portion 30 and the counter portion 60 are molded as a single unit. Also, for example, in the washbasin 10, the bowl portion 30 and the counter portion 60 are molded from the same material. For example, the washbasin 10 may be made of at least one of the following materials: ceramic, resin, and metal.

[0025] The above is merely an example, and the washbasin 10 can be configured in any way that provides the desired function. For example, the bowl portion 30 and the counter portion 60 may be individually molded and then joined together. Also, for example, different materials may be used for the bowl portion 30 and the counter portion 60. For example, the counter portion 60 may be formed by individually molding and joining together each component of the counter portion 60. Also, for example, different materials may be used for each component of the counter portion 60.

[0026] The counter section 60 has a front counter section 61, which is the rear counter section located at the back; a side counter section 62, which is the left counter section located on the left side; a side counter section 63, which is the right counter section located on the right side; and a rear counter section 64, which is the front counter section located at the front. In Figure 2, the front part of the front wall of the washbasin 10 is the front counter section 61, which is the part above the surface passing over the top surfaces of the side counter sections 62, 63 and the rear counter section 64, and the part below the surface passing over the top surfaces of the side counter sections 62, 63 and the rear counter section 64 is the front wall section 51, which will be described later.

[0027] Thus, the counter sides 62 and 63 of the counter section 60 are located at both the left and right ends of the washbasin 10. The counter sides 62 and 63 of the counter section 60 have the same shape as each other. The upper surfaces of the counter sides 62 and 63 have a planar shape. In this case, the counter sides 62 and 63 are flat surfaces.

[0028] Furthermore, the upper surface of the rear counter portion 64 may have a planar shape. In this case, the rear counter portion 64 may be a flat portion. Note that if the bowl portion 30 (for example, the rear wall portion 54) extends to the front end, the washbasin 10 does not need to have a rear counter portion 64. The counter portion 60 of the bowl portion 30 does not need to include a rear counter portion 64.

[0029] The bowl portion 30 is positioned within the counter portion 60. As a result, the bowl portion 30 is positioned between a pair of counter side portions 62 and 63. The bowl portion 30 is positioned in the center of the washbasin 10 in the left-right direction. The bowl portion 30 has a shape that is recessed downward from the upper surfaces of the counter side portions 62 and 63 and the rear counter portion 64.

[0030] The bowl portion 30 comprises a bottom portion 40 and an inner circumference portion 50. The bottom portion 40 is located at the very bottom of the bowl portion 30. As shown in Figure 3, the bottom portion 40 is surrounded by the inner circumference portion 50, which is the side portion (also called the "side portion") of the bowl portion 30. Figure 3 is a plan view of the washbasin.

[0031] The inner circumference 50 comprises a front wall portion 51 which is a rear side surface portion that is continuous with (connected to) the rear end (front end) of the bottom portion 40, a side wall portion 52 which is a left side surface portion that is continuous with the left end of the bottom portion 40, a side wall portion 53 which is a right side surface portion that is continuous with the right end of the bottom portion 40, and a rear wall portion 54 which is a front side surface portion that is continuous with the front end (rear end) of the bottom portion 40.

[0032] Each of the front wall portion 51, side wall portion 52, side wall portion 53, and rear wall portion 54 has a predetermined surface shape. For example, each of the front wall portion 51, side wall portion 52, side wall portion 53, and rear wall portion 54 may have a planar shape or a curved shape. For example, each of the front wall portion 51, side wall portion 52, side wall portion 53, and rear wall portion 54 may have a planar shape in part or a curved shape in other parts.

[0033] The bottom portion 40 is connected to the inner circumference portion 50 at both ends in the left-right direction and at both ends in the front-back direction. The bottom portion 40 comprises a bottom surface 41, a groove portion 42, and a drain opening 43. For example, the portion of the bottom portion 40 other than the groove portion 42 corresponds to the bottom surface 41. In Figure 3, the bottom surface 41 is shown distinguishing it from the surrounding portion by adding multiple dots, but these multiple dots are for indicating the range of the bottom surface 41 and do not indicate the shape of the bottom surface 41. Note that Figure 3 is merely an example, and the bottom surface 41 may be set to any range depending on the shape of the bowl portion 30.

[0034] The bottom surface 41 has a predetermined surface shape. The bottom surface 41 is a water receiving section that receives water from the faucet device 20, etc. For example, the bottom surface 41 is a flat surface having a planar shape. The bottom surface 41 is continuous with the side wall 52, the side wall 53, and the rear wall 54. For example, the bottom surface 41 has a planar shape parallel to the left-right direction. In this case, the bottom surface 41 is not inclined in the left-right direction. As shown in Figure 4, the bottom surface 41 is inclined downward toward the rear along the front-rear direction. Figure 4 is a cross-sectional view of AA in Figure 3. For example, Figure 4 shows a cross-sectional view with the drain plug 70 removed. Also, a groove 42 is connected to the rear edge of the bottom surface 41. Thus, a groove 42 is connected to the lowest edge of the bottom surface 41.

[0035] As shown in Figure 3, the groove 42 is formed parallel to the left-right direction along the front wall 51. The left end of the groove 42 is continuous with the side wall 52. The right end of the groove 42 is continuous with the side wall 53.

[0036] As shown in Figure 4, the groove 42 is recessed downward from the bottom surface 41. The groove 42 is located adjacent to the front wall 51. For example, the groove 42 is formed in a roughly rectangular shape with the left-right direction as the longitudinal direction in a plan view. The inner wall surface of the groove 42 is formed by the front wall 51. For example, in Figure 3, the area between the front wall 51 and the convex line below it corresponds to the groove 42. In Figure 3, parallel diagonal lines are used to distinguish the groove 42 from the surrounding area, but these parallel diagonal lines are only to indicate the range of the groove 42 and not to indicate the shape of the groove 42. Note that Figure 3 is merely an example, and the groove 42 may be set to any range depending on the shape of the bowl 30, the arrangement of the drain 43 (drain plug 70), etc.

[0037] The groove 42 is formed with a curved surface in a cross section perpendicular to the left-right direction corresponding to the longitudinal direction, that is, in a cross section along the front-back direction. For example, the groove 42 is formed such that in a cross section passing through the front-back and up-down directions, both ends are higher and it slopes downward towards the center.

[0038] For example, the groove 42 slopes downward from the left-right ends towards the center. The groove 42 is located at its highest point at each of the left-right ends and at its lowest point in the left-right center. A drain opening 43 is located in the center of the groove 42. The groove 42 slopes downward towards the drain opening 43 in the left-right direction.

[0039] The drain opening 43 penetrates the bowl portion 30. The drain opening 43 is connected to the drain pipe. For example, when viewed from above, the drain opening 43 has a circular shape. A portion of the rear side of the drain opening 43 overlaps with the groove portion 42. The rear surface portion 431 of the groove portion 42, which extends upward from the drain opening 43, is located on the front side of the drain opening 43.

[0040] The rear section 431 surrounds the front portion of the drain opening 43. The rear section 431 is connected to the bottom section 40 (for example, the bottom surface 41) at its upper end. The drain opening 43 is positioned so as to be recessed downward from the bottom section 40 at the left and right center of the rear side of the bottom section 40. A drain plug 70 is inserted into the drain opening 43. Note that the configuration of the drain opening 43 and the drain plug 70 is the same as in conventional designs, so a detailed explanation will be omitted.

[0041] <1-1. Water flow in a washbasin> From here, we will describe in detail the points related to the water flow in the washbasin 10 of the vanity unit 1.

[0042] As described above, the washbasin 10 has a bottom surface 41 which is a water receiving section. The rear wall 54 is an inclined section that slopes upward toward the rear from the rear end of the bottom surface 41. The groove 42 is located in front of the bottom surface 41 and is formed as a recess below the bottom surface 41. The side wall sections 52 and 53 are provided at both ends of the groove 42 and the bottom surface 41. The drain 43 drains the water that flows into the groove 42 (to the drain pipe). For example, as shown in Figure 3, the side wall sections 52 and 53 are formed to slope outwards.

[0043] As shown in Figures 1 and 2, the faucet device 20 is positioned above the bowl portion 30 (bottom surface 41, etc.) of the washbasin 10. In Figure 2, the imaginary line LC extending from the spout (discharge part) of the faucet device 20 toward the bottom surface 41 of the bowl portion 30 is a straight line extending in the direction facing the spout of the faucet device 20. For example, in the washbasin vanity 1, the point on the bottom surface 41 where the imaginary line LC intersects is the point where the water hits. As shown in Figure 2, the faucet device 20 discharges water diagonally downward (diagonally backward) from the spout (discharge part).

[0044] Here, as shown in the water discharge IR in Figure 4, the water discharged from the faucet device 20 is released toward the bowl portion 30 with a certain width. Therefore, the water discharged from the faucet device 20 lands within a predetermined range on the bottom surface 41, as shown in the landing range WA in Figure 5. Figure 5 is a plan view showing the relationships between the elements of the washbasin.

[0045] The area of ​​the bottom surface 41 where water discharged from the spout of the faucet device 20 lands is also called the landing surface 411. As shown in Figure 5, the range of the landing surface 411 corresponds to (matches) the landing range WA. Note that the landing range WA shown in Figure 2, etc., is merely an example, and the landing range may change depending on the shape of the water discharge from the spout of the faucet device 20. For example, the landing range WA shown in Figure 2, etc., may be the landing range when the faucet device 20 is spraying water in a shower. For example, water may be discharged from the spout of the faucet device 20 at a flow rate of 3 liters per minute.

[0046] As shown in Figure 6, at least a portion of the water that lands on the bottom surface 41 forms a main flow F11, which is a flow of water that flows toward the rear wall 54, which is an inclined section, and a flow of water that flows toward the front (rear). Figure 6 is a plan view showing an overview of the water flow in the washbasin. After the main flow F11 collides with the rear wall 54, it splits into a first flow F12, which flows toward one of the side walls 52 (left side), and a second flow F13, which flows toward the other side wall 53 (right side). The first flow F12 flows into the groove 42 along the side wall 52, which is the left side continuous with the left end of the bottom 40, and the second flow F13 flows into the groove 42 along the side wall 53, which is the right side continuous with the right end of the bottom 40.

[0047] Furthermore, as shown in Figure 5, the water landing surface 411 and the drain opening 43 are positioned to overlap in the left-right direction. In Figure 5, the left-right width W11 of the water landing surface 411 is greater than the left-right width W12 of the drain opening 43. As a result, in the washbasin vanity 1, a portion of the water that hits the vanity goes directly to the groove 42, and the film of water heading towards the groove 42 makes it easier for the first flow F12 and the second flow F13 to spread out to the left and right.

[0048] Note that the landing surface 411 shown in Figures 2, 5, and 6 is merely an example, and the landing surface 411 may be set to any range including the landing point. For example, the landing surface 411 is merely an example, and the landing surface 411 may be set to a range that includes at least a part of the landing range WA. Also, in Figure 5, the landing surface 411 is positioned behind the center in the front-rear direction of the bottom surface 41. For example, the landing surface 411 is positioned such that at least a part of it is located behind the center in the front-rear direction of the bottom surface 41. In Figure 5, the landing surface 411 is positioned such that the entire landing surface 411 is located behind (in front of) the center line CL in the front-rear direction of the bottom surface 41.

[0049] Thus, in the vanity unit 1, water that hits the bottom surface 41, which is the water receiving section, can be guided by the inclined rear wall section 54 towards the side walls 52 and 53 located at the left and right ends, so that water can be reliably supplied to both the left and right ends of the groove section 42. Therefore, the vanity unit 1 allows water that hits the washbasin 10 to flow properly within the washbasin 10.

[0050] <2. Variant> The embodiments described above are merely examples, and the configuration of the washbasin and other components of the vanity unit may have various structures. In this regard, several embodiments will be described below as modifications.

[0051] <2-1. First variation> First, the configuration shown in Figure 7 will be described as the washbasin 10A according to the first modified example. Figure 7 is a plan view of the washbasin according to the first modified example. Note that explanations of points similar to those described in the above-mentioned embodiments will be omitted as appropriate.

[0052] In the washbasin 10A according to the first modified example, the inclined rear wall portion 54 has a rounded shape in plan view and protrudes further to the rear as it approaches the center. Of the side wall portions 52 and 53, one flow flows toward one side wall portion 52 (left side), and the other flow flows toward the other side wall portion 53 (right side) flows along the rounded rear wall portion 54, and the flow spreads out to both ends of the groove portion 42.

[0053] As shown in Figure 8, at least a portion of the water that lands on the bottom surface 41 forms a main flow F21, which is a water flow toward the rear wall 54, which is an inclined section, and a water flow toward the front (rear). Figure 8 is a plan view showing an overview of the water flow in a washbasin.

[0054] As shown in Figure 8, after the main flow F21 collides with the rear wall 54, it splits into a first flow F22, which flows toward one of the side walls 52 (left side), and a second flow F23, which flows toward the other side wall 53 (right side). The first flow F22 flows into the groove 42 along the side wall 52, which is the left side continuous with the left end of the bottom 40, and the second flow F23 flows into the groove 42 along the side wall 53, which is the right side continuous with the right end of the bottom 40.

[0055] In the washbasin 10A, because the rear wall portion 54 has a rounded shape, as shown in Figure 8, the first flow F22, which flows toward the side wall portion 52, and the second flow F23, which flows toward the side wall portion 53, flow along the rounded rear wall portion 54, and the flow spreads out to both ends of the groove portion 42.

[0056] Thus, the washbasin 10A shown in Figure 7 can guide water to the left and right ends along the inclined rear wall portion 54, making it possible to more reliably ensure that water flows into the left and right ends. Therefore, in the washbasin vanity 1 according to the first modified example, water that has entered the washbasin 10A can flow properly within the washbasin 10A.

[0057] <2-2. Second variation> Next, the configuration shown in Figure 9 will be described as the washbasin 10B according to the second modified example. Figure 9 is a plan view of the washbasin according to the second modified example. Details similar to those described in the above-mentioned embodiments will be omitted as appropriate.

[0058] In the second modified washbasin 10B, the bottom surface 41 is trapezoidal in plan view, with the groove 42 side as the upper bottom (shorter bottom (side)). In the washbasin 10B, in plan view, the distance between the side walls 52 and 53 decreases towards the front. In the example shown in Figure 9, the distance W22 between the side walls 52 and 53 on the front side of the bowl 30 is shorter (smaller) than the distance W21 between the side walls 52 and 53 on the rear side.

[0059] As shown in Figure 10, at least a portion of the water that lands on the bottom surface 41 forms a main flow F31, which is a water flow toward the rear wall 54, which is an inclined section, and a water flow toward the front (rear). Figure 10 is a plan view showing an overview of the water flow in a washbasin.

[0060] As shown in Figure 10, after the main flow F31 collides with the rear wall 54, it splits into a first flow F32, which flows toward one of the side walls 52 (left side), and a second flow F33, which flows toward the other side wall 53 (right side). The first flow F32 flows into the groove 42 along the side wall 52, which is the left side continuous with the left end of the bottom 40, and the second flow F33 flows into the groove 42 along the side wall 53, which is the right side continuous with the right end of the bottom 40.

[0061] In the washbasin 10B, the distance W22 between the side walls 52 and 53 on the front side of the bowl portion 30 is smaller than the distance W21 between the side walls 52 and 53 on the rear side of the bowl portion 30. In other words, in the washbasin 10B, the bowl portion 30 is formed so that its width narrows as it moves towards the front. Therefore, in the washbasin 10B, as shown in Figure 10, the flow gathers along the side walls 52 and 53 as it moves towards the groove portion 42, and flows into both ends of the groove portion 42.

[0062] Thus, the washbasin 10B shown in Figure 9 can cause the water flow (main stream, etc.) to collide with the rear wall 54 without weakening its force, and can be guided to the left and right ends. Therefore, in the washbasin vanity 1 according to the second modified example, the water that hits the washbasin 10B can flow properly within the washbasin 10B.

[0063] <2-3. Third variation> Next, the configuration shown in Figure 11 will be described as the washbasin 10C according to the third modified example. Figure 11 is a plan view of the washbasin according to the third modified example. Note that explanations of points similar to those described in the above embodiments will be omitted as appropriate.

[0064] In the third modified example, the washbasin 10C has a flat shape in the front-to-back direction, or a downward slope toward the rear, on at least the water landing surface 411 of the bottom surface 41. In Figure 11, the water landing surface 411 of the washbasin 10C has a flat shape in the front-to-back direction. In addition, in the washbasin 10C, the portion of the bottom surface 41 other than the water landing surface 411 has an upward slope in the front-to-back direction, similar to the bottom surface 41 of the washbasin 10 shown in Figure 4. The water landing surface 411 of the washbasin 10C may also have a downward slope toward the rear in the front-to-back direction.

[0065] Thus, the washbasin 10C shown in Figure 11 has a flat shape in the front-to-back direction, or a water landing surface 411 that slopes downward toward the rear, which suppresses the decrease in the force of the water that lands on the bottom surface 41, which is the water receiving section, and can guide a strong main flow toward the rear wall section 54, which is the sloped section, making it easier to spread the first flow and the second flow over a wider area in the left-to-right direction. As a result, the washbasin vanity 1 according to the third modified example can guide the water to the end of the groove section 42 more reliably, regardless of the width of the washbasin 10C. Therefore, the washbasin vanity 1 according to the third modified example can allow the water that lands on the washbasin 10C to flow properly inside the washbasin 10C.

[0066] It should be noted that the embodiments and modifications described above are merely examples, and any configuration can be adopted for the washbasin and vanity unit as long as they have the desired functions. For example, a washbasin may be constructed by combining two or more of the embodiments and modifications that can be combined.

[0067] Further effects and modifications can be readily derived by those skilled in the art.
