Description

lamp module

[0001] The present invention relates to a lamp module that generates ultraviolet rays.

[0002] Generally, ultraviolet lamps generate ultraviolet rays and are used in various applications for the purpose of sterilizing bacteria and fungi. Ultraviolet lamps generate ultraviolet rays (UV) of various wavelengths based on materials supplied inside the lamp. For example, they can generate UV-A (315 nm to 400 nm), UV-B (280 nm to 315 nm), and UV-C (100 nm to 280 nm). Among these, ultraviolet rays with a wavelength of 2537 nm, corresponding to UV-C, have the most superior sterilizing power; when bacteria and fungi are irradiated with UV-C, their DNA is damaged, causing them to die. Therefore, sterilization using ultraviolet lamps is more efficient than sterilization by heat, chemicals, ozone, or radiation. However, since ultraviolet rays damage the DNA of living organisms, caution is required to prevent exposure to humans.

[0003] The magnitude of the initial onset voltage is very important for igniting such UVC ultraviolet lamps. Depending on the structure of the lamp, the minimum ignition voltage is significantly affected by the contact area between the lamp and the electrode at adjacent positions of the counter electrode; if the electrode contact area is small relative to the lamp size at ignition, a high ignition voltage is required. In other words, as the lamp size increases, the distance between the electrodes also increases, requiring a high ignition voltage. In this case, the allowable voltage of the inverter must be increased, which leads to an increase in the volume of the transformer and other components, affecting the size of the application product and also increasing the amount of harmful electromagnetic waves generated.

[0004] Meanwhile, conventional general lamp modules utilize fastening pieces to maintain constant contact between the lamp and the electrode. As one of the prior art methods for fastening the lamp and the electrode with such pieces, Korean Published Patent Application No. 10-2023-0144213 (published on October 16, 2023; hereinafter referred to as the prior art) discloses a technology for inducing large-area ultraviolet light by arranging multiple tubular lamps. However, the technology disclosed in the prior art had limitations, such as a complex lamp assembly process and the risk of lamp damage due to strong pressure applied to the lamp during fastening with the pieces. Furthermore, when the lamp is lit for a long time, a minute gap is created between the electrode and the lamp at the fastening point due to thermal shrinkage, which affects the lighting. Moreover, since the modules are fastened using multiple screws, the process consumes a significant amount of time, and costs inevitably increase.

[0005] The present invention aims to improve upon the limitations of the prior art as described above.

[0006] Accordingly, the present specification aims to provide an embodiment that can fix a lamp without fastening a piece.

[0007] In addition, we intend to provide an embodiment that can effectively generate a lamp discharge without fastening a piece.

[0008] Furthermore, we intend to provide an embodiment in which efficient and safe ultraviolet radiation can be achieved while continuously maintaining the coupling between the lamp and the electrode.

[0009] The present invention, for solving the problem described above, provides a solution means in which an electrode formed in the longitudinal direction of a lamp comes into contact with the lamp, and a housing is fitted and coupled to both ends of the electrode.

[0010] Specifically, a lamp is mounted on a pair of electrodes and housings are attached to both ends, so that contact between the lamp and the electrodes is maintained by the housings at both ends.

[0011] Accordingly, the module can be configured without fastening pieces, and the high voltage required between the two electrodes can be maintained constant even if the length of the lamp is increased, thereby enabling the induction of ultraviolet rays with a low voltage regardless of the length of the lamp.

[0012] An embodiment of a lamp module having such technical features as a means of solution comprises a lamp formed in a rod shape, a plurality of electrodes formed in the longitudinal direction of the lamp such that a portion of the radiating surface of the lamp contacts and is seated thereon, and a housing comprising a first housing portion and a second housing portion to which the assembly is fitted at both ends in the longitudinal direction of the assembly in which the lamp is seated on the plurality of electrodes, wherein the housing has an opening formed from one end to the other end of its upper surface so that a portion of the radiating surface protrudes into the opening when coupled with the assembly, and the opening is formed such that the one end and the other end have a first width, and the central portion excluding the one end and the other end has a second width that is wider than the first width.

[0013] The embodiments of the lamp module described above are not limited to those described above and may include embodiments described in the specific description below or inferred / derived from the specific description.

[0014] According to an embodiment of the lamp module of the present specification, an electrode formed in the longitudinal direction of the lamp is in contact with the lamp, and by fitting a housing to both ends of the electrode, the contact between the lamp and the electrode can be fixed without fastening a piece.

[0015] In addition, by forming the electrode along the length of the lamp, the contact area between the lamp and the electrode can be maximized, and the lamp's discharge can be effectively generated.

[0016] Accordingly, not only can the lamp module be manufactured even if the length of the lamp is changed, but the lamp module can also be utilized in various ways, thereby increasing the usability and versatility of the lamp module.

[0017] Furthermore, since the housing is formed of a material having a certain elasticity, it is possible to continuously maintain close contact between the lamp and the electrode even if minute thermal expansion and contraction occur between them.

[0018] Accordingly, the ultraviolet radiation from the lamp can be efficiently sustained.

[0019] In addition, by ensuring that the electrode is not exposed to the radiating surface where ultraviolet rays are emitted, the safety of using the lamp can be increased.

[0020] In addition, by connecting the lamp and the electrode simultaneously without fastening the pieces, the assembly process can be simplified, thereby reducing the time and cost consumed in the assembly process of the lamp module.

[0032] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings; however, in describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art may obscure the essence of the embodiments disclosed in this specification, such detailed description will be omitted.

[0033] In addition, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included.

[0034] A lamp module (100) according to an embodiment includes a lamp (10), an electrode (20), and a housing (30), as shown in FIG. 1, wherein a portion of the radiating surface of the lamp (10) is exposed to the upper part of the lamp module (100).

[0035] In this way, the lamp module (100) has a portion of the radiating surface of the lamp (10) exposed to the upper surface of the housing (30), and the electrode (20) is blocked from being exposed to the upper surface by the housing (30).

[0036] The configuration and assembly process of the lamp module (100) including the lamp (10), the electrode (20), and the housing (30) may be as shown in FIGS. 2 and FIGS. 3.

[0037] In the lamp module (100) above, the lamp (10) is formed in a rod shape.

[0038] The above lamp (10) may be a lamp formed in a cylindrical shape.

[0039] The above lamp (10) may be a tubular lamp.

[0040] The above lamp (10) may be a lamp that emits ultraviolet light through a radiating surface.

[0041] For example, the lamp (10) may be a Far-UVC ultraviolet lamp.

[0042] The lamp (10) is combined with the electrode (20) and the housing (30), so that a portion of the radiating surface may be exposed to the upper surface of the housing (30).

[0043] As shown in FIG. 3, the lamp (10) is seated on the electrode (20) at the top of the electrode (20), and the housing (30) can be fitted and coupled at both ends of the state (A) in which it is seated on the electrode (20).

[0044] Here, the above ends may correspond to the left and right ends of the lamp module (100) when the lamp module (100) is viewed from the Z-axis, which is orthogonal to the X-axis corresponding to the length direction of the lamp (10).

[0045] In the lamp module (100), the electrode (20) is formed in the longitudinal direction of the lamp (10), so that a portion of the radiating surface of the lamp (10) comes into contact with and is seated.

[0046] The above electrode (20) may be composed of a plurality (21, 22).

[0047] A plurality of electrodes (21, 22) are positioned on each of the lower sides of the lamp (10) when viewed from the front in the longitudinal direction, so that a portion of the lower radiating surface of the lamp (10) can be contacted and seated as shown in FIG. 3.

[0048] In this way, by contacting and settling the lamp (10) on the plurality of electrodes (21, 22), a combined body (A) in which the lamp (10) and the plurality of electrodes (21, 22) are combined can be formed.

[0049] The plurality of electrodes (21, 22) can be electrically connected to the lamp (10) by contacting a portion of the lower radiating surface of the lamp (10).

[0050] The plurality of electrodes (21, 22) are connected to an external power source, so that the power source and the lamp (10) can be electrically connected.

[0051] Accordingly, power is applied to the lamp (10) from the power source through the plurality of electrodes (21, 22), thereby allowing ultraviolet light to be generated in the lamp (10).

[0052] In this case, the plurality of electrodes (21, 22) can be connected to power terminals of different polarities.

[0053] For example, a + terminal can be connected to the first electrode (21) and a - terminal to the second electrode.

[0054] Accordingly, the plurality of electrodes (21, 22) may have different polarities.

[0055] The plurality of electrodes (21, 22) may include a pair of electrodes formed in shapes symmetrical to each other.

[0056] That is, the plurality of electrodes (21, 22) may consist of at least one pair of electrodes that are symmetrical to each other.

[0057] Each of the above plurality of electrodes (21, 22) may also be composed of one or more electrode parts.

[0058] For example, the first electrode (21) may include a first-1 electrode part fitted into the first housing part (31) and a first-2 electrode part fitted into the second housing part (32).

[0059] Additionally, the second electrode (22) may include a second-1 electrode portion fitted into the first housing portion (31) and a second-2 electrode portion fitted into the second housing portion (32).

[0060] The plurality of electrodes (21, 22) may be formed such that one or more of their specifications and shapes are identical.

[0061] The plurality of electrodes (21, 22) above can preferably be formed with the same specifications and shape.

[0062] Accordingly, the plurality of electrodes (21, 22) can be formed using two identical electrodes.

[0063] As shown in FIG. 3, the plurality of electrodes (21, 22) can be formed with a length (L) such that when the lamp (10) is seated, both ends of the lamp (10) do not protrude at both ends in the longitudinal direction.

[0064] That is, the plurality of electrodes (21, 22) can be formed with a length greater than the length of the lamp (10).

[0065] The plurality of electrodes (21, 22) can preferably be formed with a length equal to the length of the lamp (10).

[0066] In the lamp module (100), the housing (30) includes the first housing part (31) and the second housing part (32) to which the assembly (A) is fitted at both ends in the longitudinal direction of the assembly (A) on which the lamp (10) is seated on the plurality of electrodes (21, 22) as shown in FIG. 3.

[0067] One end of the assembly (A) can be fitted into the first housing part (31), and the other end of the assembly (A) can be fitted into the second housing part (32).

[0068] Each of the first housing part (31) and the second housing part (32) may have an opening (E1, E2) formed on its upper surface.

[0069] The openings (E1, E2) of the first housing part (31) may include one end (E1) in the outer direction (-X) of the first housing part (31) and the other end (E2) in the inner direction (X) of the first housing part (31).

[0070] The openings (E1, E2) of the second housing part (32) may include one end (E1) in the outer direction (X) of the second housing part (32) and the other end (E2) in the inner direction (X) of the second housing part (32).

[0071] The first housing part (31) and the second housing part (32) may be formed with one or more of the same specifications and shapes.

[0072] The first housing part (31) and the second housing part (32) can preferably be formed with the same specifications and shape.

[0073] Accordingly, the first housing part (31) and the second housing part (32) can be configured using two identical housing parts.

[0074] As each of the first housing part (31) and the second housing part (32) is fitted together at both ends of the assembly (A), the lamp module (100) in which the lamp (10), the electrode (20), and the housing (30) are combined can be formed as shown in FIG. 1.

[0075] That is, the lamp module (100) can be assembled into a module shape as shown in FIG. 1 by having the lamp (10), the plurality of electrodes (21, 22), the first housing part (31), and the second housing part (32) arranged as shown in FIG. 2, and then having the lamp (10) placed on the plurality of electrodes (21, 22) as shown in FIG. 3, and then having the first housing part (31) and the second housing part (32) each joined at both ends of the assembly (A).

[0076] In the lamp module (100) in which the lamp (10) is formed in a rod shape and the plurality of electrodes (21, 22) are formed in the longitudinal direction of the lamp (10), so that the lamp (10) is seated in contact with a portion of the radiating surface, and the first housing part (31) and the second housing part (32) are each fitted together with the assembly (A) at both ends in the longitudinal direction of the assembly (A), the housing (30) has an opening (E) formed from one end (31E1) of the upper surface to the other end (32E1), so that when combined with the assembly (A), a portion of the radiating surface protrudes into the opening (E).

[0077] That is, the lamp module (10) may have a portion of the radiating surface of the lamp (10) exposed through the opening (E) formed on the upper surface of the housing (30).

[0078] Here, the first end (31E1) corresponds to the first end (E1) of the first housing part (31), and the other end (32E1) may correspond to the first end (E1) of the second housing part (32).

[0079] The specific configuration of the opening (E) described above may be as shown in FIG. 4.

[0080] FIG. 4 is a top view of the housing (30) as seen from above. As shown in FIG. 4, the opening (E) is formed such that the first end (31E1) and the other end (32E1) have a first width (D1), and the central part (31E2, 32E2), excluding the first end (31E1) and the other end (32E1), has a second width (D2) that is wider than the first width (D1).

[0081] That is, the opening (E) is formed such that the width of the central part (31E2, 32E2) is wider than that of the first part (31E1) and the other part (32E1).

[0082] Here, the central part (31E2, 32E2) may correspond to the other end (E2) of the first housing part (31) and the other end (E2) of the second housing part (32).

[0083] In this way, the first end (31E1) and the other end (32E1) are formed with a first width (D1) that is narrower than the second width (D2), so that both ends of the lamp (10) are covered by the housing (30) and can be supported in a fixed state.

[0084] In addition, by forming the central portion (31E2, 32E2) with a second width (D2) that is wider than the first width (D1), the limitation of the amount of light generated from the central radiating surface of the lamp (10) can be minimized.

[0085] The first width (D1) and the second width (D2) may vary depending on the specifications of one or more of the lamp (10) and the electrode (20).

[0086] Each of the above-mentioned first end (31E1) and the above-mentioned second end (32E1) can be formed with a first length (P1).

[0087] That is, each of the first housing part (31) and the second housing part (32) can be formed with the first length (P1).

[0088] In this case, each of the above central portions (31E2, 32E2) may be formed with a second length (P2) greater than or equal to the first length (P1).

[0089] That is, the other end (E2) of the first housing part (31) and the other end (E2) of the second housing part (32) can each be formed with a second length (P2) greater than or equal to the first length (P1).

[0090] Accordingly, the central portion (31E2, 32E2) may be formed with a length (P1+P1 ≤ P2 * 2) that is the sum of the first portion (31E1) and the other portion (32E1).

[0091] The first length (P1) and the second length (P2) may vary depending on the specifications of one or more of the lamp (10) and the electrode (20).

[0092] In this way, each of the first end (31E1) and the other end (32E1), formed with the first width (D1) and the first length (P1), can be formed in the shape of a rectangle.

[0093] Each of the above-mentioned first end (31E1) and the above-mentioned second end (32E1) may also be formed in a shape other than a rectangle.

[0094] Each of the above-mentioned first end (31E1) and the above-mentioned second end (32E1) can be formed in a shape where both sides are symmetrical with respect to the center when the housing (30) is viewed in the length direction (X).

[0095] The first end (E1) of the first housing part (31) and the second housing part (32) corresponding to the first end (31E1) and the other end (32E1) can preferably be formed in the same shape.

[0096] The first end portion (E1) of the first housing portion (31) and the first end portion (E1) of the second housing portion (32) may also be formed in different shapes.

[0097] Additionally, each of the central portions (31E2, 32E2) formed by the second width (D2) and the second length (P2) can be formed in the shape of a rectangle.

[0098] Each of the above central portions (31E2, 32E2) may also be formed in a shape other than a square.

[0099] Each of the above central portions (31E2, 32E2) can be formed in a shape that is symmetrical on both sides with respect to the center when the housing (30) is viewed in the length direction (X).

[0100] The other end (E2) of the first housing part (31) and the other end (E2) of the second housing part (32), corresponding to the central part (31E2, 32E2), can preferably be formed in the same shape.

[0101] The other end (E2) of the first housing part (31) and the other end (E2) of the second housing part (32) may also be formed in different shapes.

[0102] In this way, the lamp module (100) is formed such that the plurality of electrodes (21, 22) are formed in the longitudinal direction of the lamp (10), and the housing (30) is joined and fixed at both ends, thereby allowing the lamp module (100) to be assembled without fastening pieces.

[0103] In addition, the lamp module (100) has the plurality of electrodes (21, 22) formed along the length of the lamp (10), and the housing (30) is connected and fixed at both ends, so that the configuration according to the length of the lamp (10) can be easily achieved.

[0104] Accordingly, even if the length of the lamp (10) is changed, if the electrode (20) and the housing (30) are manufactured in correspondence with the length of the lamp (10), the assembly and configuration of the lamp module (100) can be easily achieved.

[0105] In addition, the lamp module (100) can improve the support strength and light efficiency of the lamp (10) through the opening (E), thereby enabling stable and efficient radiation compared to conventional lamp modules.

[0106] Specific embodiments of the lamp module (100) are described below.

[0107] FIGS. 5 to 7 are cross-sectional views of each configuration of the lamp module (100) viewed from the X-axis direction, and the lamp module (100) may be implemented in a form different from that shown in FIGS. 5 to 7.

[0108] FIG. 5 is a cross-sectional view of the assembly (A) in which the lamp (10) is seated on the plurality of electrodes (21, 22), FIG. 6 is a cross-sectional view of the housing (30), and FIG. 7 is a cross-sectional view of the assembly (A) and the housing (30) combined.

[0109] As shown in FIG. 5, at least a portion of the contact surface (F) that contacts the radiating surface of the lamp (10) of the plurality of electrodes (21, 22) may be formed as a curved surface.

[0110] The plurality of electrodes (21, 22) may have the contact surface (F) formed as a concave surface corresponding to the radiating surface.

[0111] Accordingly, as the radiating surface formed in an arc shape is seated on the contact surface (F) formed in a concave shape, each of the plurality of electrodes (21, 22) can stably support the seating of the lamp (10) on both sides of the lower part of the lamp (10).

[0112] The plurality of electrodes (21, 22) can be positioned such that when the lamp (10) is seated, the center circle of the lamp (10) is positioned at the height of the upper surface.

[0113] That is, the plurality of electrodes (21, 22) may cover a portion of the lower semicircle of the lamp (10).

[0114] Each of the above plurality of electrodes (21, 22) may be in contact with less than half of the lower radiating surface of the lamp (10).

[0115] Accordingly, each of the plurality of electrodes (21, 22) may cover a portion of the lower radiation surface, less than 50%.

[0116] Each of the above plurality of electrodes (21, 22) may have at least a portion of the outer surface (R) that contacts the housing (30) when fitted into the housing (30) formed as a curved surface.

[0117] Each of the above plurality of electrodes (21, 22) may have at least a portion of the outer surface (R) formed as a concave surface.

[0118] That is, each of the plurality of electrodes (21, 22) may have at least a portion of the outer surface (R) formed concavely.

[0119] As shown in FIG. 5, each of the plurality of electrodes (21, 22) may have an upper portion (R1) and a lower portion (R3) of the outer surface (R) formed as convex surfaces, and a concave surface formed between the convex surfaces (R1, R3) (R2).

[0120] In this case, the housing (30) may have guide grooves (H1, H2, H3) formed in a shape corresponding to the outer surfaces (R1, R2, R3) on the inner surface (H) of the coupling part to which the coupling member (A) is fitted, as shown in FIG. 6.

[0121] Accordingly, as shown in FIG. 7, the outer surfaces (R1, R2, R3) are in close contact with the guide grooves (H1, H2, H3), and the assembly (A) can be fitted into the housing (30).

[0122] In this way, each of the upper portion (R1) and lower portion (R3) of each of the plurality of electrodes (21, 22) is formed as a convex surface, and a concave surface is formed between (R2) the convex surfaces (R1, R3), and guide grooves (H1, H2, H3) corresponding to the convex surfaces (R1, R3) and the concave surface (R2) are formed on the inner surface (H) of the housing (30), thereby increasing the coupling support force on both sides when the assembly (A) and the housing (30) are coupled, and making it easy to perform a snap-fit ​​coupling.

[0123] In particular, by forming an upper convex surface (R1) on the upper side of the concave surface (R2) and a lower convex surface (R3) on the lower side of the concave surface (R2), it is possible to prevent vertical direction (Y) vibration and detachment of the assembly (A).

[0124] Accordingly, the bonding strength between the assembly (A) and the housing (30) is improved, thereby allowing the structure of the lamp module (100) to be maintained stably.

[0125] The plurality of electrodes (21, 22) can also be spaced apart by a certain distance (G) between their respective lower portions when the lamp (10) is seated, as shown in FIG. 5.

[0126] In this way, the lower portions of the plurality of electrodes (21, 22) are spaced apart by the aforementioned predetermined distance (G), thereby preventing contact between the plurality of electrodes (21, 22) and preventing the influence between each electrode according to the voltage intensity, so that the light emission of the lamp (10) can be achieved stably.

[0127] Here, the above constant distance (G) may be a distance within the range of 2 to 10 [mm].

[0128] In this case, the housing (30) may have a guide tab (T) formed on the lower surface of the coupling part to which the coupling member (A) is fitted, as shown in FIG. 6, in a shape that is inserted between the lower parts.

[0129] Accordingly, when the assembly (A) and the housing (30) are combined as shown in FIG. 7, a certain distance (G) between the plurality of electrodes (21, 22) can be maintained by the guide tab (T).

[0130] Meanwhile, the guide tab (T) can be formed at a height that does not come into contact with the lamp (10) when the assembly (A) is fitted together.

[0131] Accordingly, when the assembly (A) and the housing (30) are combined as shown in FIG. 7, the guide tab (T) is not in contact with the lamp (10), and a gap (S) is formed between the lamp (10) and the guide tab (T), thereby preventing the burning / breakage of the lower part of the lamp (10) by the guide tab (T) and the deformation of the combined structure of the lamp module (100) due to the heat generated from the lamp (10).

[0132] In addition, heat dissipation and cooling of the heat generated in the lamp (10) can be achieved through the above-mentioned gap (S), thereby enabling stable operation and increased lifespan of the lamp (10).

[0133] Meanwhile, each of the first housing part (31) and the second housing part (32) may be fitted together at both ends of the assembly (A) to form the exterior of the lamp module (100) as shown in FIG. 1.

[0134] FIG. 8 is an exemplary diagram for explaining the internal coupling state of the assembly (A) and the housing (30) in the lamp module (100) as illustrated in FIG. 1, showing a state in which the coupling of the second housing part (32) of the housing (30) is omitted.

[0135] Each of the first housing part (31) and the second housing part (32) may have an upper frame formed such that both sides of the upper portion protrude in the longitudinal direction of the assembly (A).

[0136] In this way, the upper frame is formed on both sides of the upper portion of each of the first housing portion (31) and the second housing portion (32), so that when the housing (30) is combined with the assembly (A), the upper frame of the first housing portion (31) and the upper frame of the second housing portion (32) can be in close contact with each other as shown in FIG. 1.

[0137] Accordingly, the upper frame prevents each of the plurality of electrodes (21, 22) from being exposed to the upper part of the lamp module (100), and also protects the lamp (10) and each of the plurality of electrodes (21, 22) from external impact.

[0138] That is, the upper frame may cover the plurality of electrodes (21, 22).

[0139] When the above housing (30) is combined with the above assembly (A), a portion of each of the plurality of electrodes (21, 22) may be exposed on both sides of the lower part of the upper frame.

[0140] As such, the portions where the plurality of electrodes (21, 22) are exposed on both sides of the lower part of the upper frame can be a mounting portion for mounting the lamp module (100) to a device in which it is used.

[0141] For example, a power supply terminal of an external power source for supplying power to each of the plurality of electrodes (21, 22) may be connected to the portions on both sides of the bottom of the upper frame where the plurality of electrodes (21, 22) are exposed.

[0142] Meanwhile, as shown in FIGS. 2, FIGS. 3, FIGS. 6 and FIGS. 7, the housing (30) may be formed such that the exposed surface of the upper frame exposed to the opening (E) has a slope.

[0143] Here, the exposed surface may correspond to the edge (EDGE) of the upper frame forming the opening (E).

[0144] The above housing (30) may have the exposed surface of the one end (31E1), the exposed surface of the other end (32E1), and the exposed surface of the central part (31E2, 32E2) formed at different slopes.

[0145] One or more of the exposed surfaces of the above-mentioned first end (31E1) and the above-mentioned second end (32E1) may be formed with a slope such that the width decreases in the direction (-Y) toward the interior of the housing (30) from the upper surface, as shown in FIGS. 2, 3, 6 and 7.

[0146] That is, one or more of the exposed surfaces of the first end (31E1) and the other end (32E1) may be formed with an incline facing the lamp (10).

[0147] Preferably, the exposed surfaces of each of the first end (31E1) and the other end (32E1) may be sloped so that their width decreases in the direction (-Y) toward the interior of the housing (30) from the upper surface.

[0148] In this way, in order to support the connection of the assembly (A) at both ends, the exposed surfaces of the first end (31E1) and the other end (32E1), which are formed with a first width (D1) narrower than the central part (31E2, 32E2), are formed with a slope such that the width decreases in the direction toward the interior of the housing (30) from the upper surface, thereby preventing the ends of the lamp (10) from being disengaged from the opening (E).

[0149] The exposed surface of the central portion (31E2, 32E2) may be sloped so that its width increases in the direction (-Y) toward the interior of the housing (30) from the upper surface, as shown in FIGS. 2, 3, 6 and 7.

[0150] That is, the exposed surface of the central part (31E2, 32E2) may be formed with a slope facing the upper surface.

[0151] In this way, to secure the amount of light from the lamp (10), the exposed surface of the central part (31E2, 32E2), which is formed with a second width (D2) wider than the first part (31E1) and the other part (32E1), is sloped so that its width increases in the direction toward the interior of the housing (30) from the upper surface, thereby allowing the amount of light emitted from the lamp (10) to spread along the exposed surface of the central part (31E2, 32E2) and be emitted toward the upper surface.

[0152] FIG. 9 is a graph showing the results of measuring the high voltage when the lamp module (100) is configured with the length of the lamp (10) as 4 [cm], 5 [cm], and 6 [cm]. As shown in FIG. 9, it can be confirmed that even if the length of the lamp (10) increases, the change in the high voltage required to drive the lamp (10) is not significant.

[0153] Accordingly, the lamp module (100) is configured such that the high voltage does not change significantly even when the length of the lamp (10) is changed, so that the operation of the lamp (10) can be performed stably.

[0154] FIG. 10 is a graph showing the assembly time of the lamp module (100) and the assembly method of the conventional screw fastening method. As shown in FIG. 10, the time consumed by the assembly method of the lamp module (100) that does not use screws is 4 seconds, and it can be seen that the assembly time is reduced by 50% compared to the screw fastening method which takes 8 seconds or more.

[0155] Accordingly, the lamp module (100) can reduce the time and cost consumed in the assembly process and prevent the lamp (10) or the housing (30) from being damaged by fastening the pieces.

[0156] Although embodiments of the lamp module described above have been explained so far, various modifications are possible to the described embodiments without departing from the scope of the present invention, and the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
