Description

Technical Field

[0001] This utility model relates to the field of lamp tubes, and in particular to an energy-saving UV-resistant lamp tube. Background Technology

[0002] The semiconductor and printing industries typically require UV-resistant lamps, which filter out most of the ultraviolet light emitted by the ambient light. Existing UV-resistant lamps typically consist of a heat sink, a light strip, a UV-resistant transparent panel, and a reflector. The light strip is mounted on the heat sink, and the transparent panel is also mounted on the heat sink with the light-emitting side of the light strip facing the transparent panel. The reflector is mounted on the heat sink and reflects the edge light from the light strip back to the transparent panel. The single-layer structure of the UV-resistant transparent panel needs to simultaneously filter UV light and prevent glare, resulting in relatively poor light transmittance of the UV-resistant transparent panel. This necessitates the use of high-power light strips to meet lighting requirements, leading to relatively high energy consumption. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an energy-saving UV-resistant lamp tube that provides good lighting performance while being relatively energy-efficient.

[0004] An energy-saving UV-resistant lamp tube according to an embodiment of the present invention includes a heat sink, a light-emitting strip, a light-transmitting cover assembly, and a reflector. The heat sink has a light strip mounting position, the heat sink being strip-shaped and extending along a first direction; the light-emitting strip is disposed on the heat sink and located at the light strip mounting position, the light-emitting strip extending along the first direction, and the light-emitting strip having a light-emitting side; the light-transmitting cover assembly is disposed on the heat sink, the light-transmitting cover assembly being strip-shaped and extending along the first direction, the light-transmitting cover assembly including stacked diffuser light-transmitting plates and UV-resistant light-transmitting plates, the light-emitting side of the light-emitting strip facing the light-transmitting cover assembly; the reflector is disposed on the heat sink, the reflector being strip-shaped and extending along the first direction, and the side of the reflector facing the light-transmitting cover assembly has a reflective surface.

[0005] The energy-saving anti-UV lamp tube according to the embodiments of this utility model has at least the following beneficial effects: part of the light emitted by the light-emitting strip passes directly through the light-transmitting cover assembly, and part of it is reflected by the reflector and then passes through the light-transmitting cover assembly. The light-transmitting cover assembly includes a stacked diffuser light-transmitting plate and an anti-UV light-transmitting plate. The diffuser light-transmitting plate diffuses and prevents glare from the light emitted by the light-emitting strip, while the anti-UV light-transmitting plate filters ultraviolet light. By processing the two separately and stacking them to form the light-transmitting cover assembly, the anti-UV light-transmitting plate does not need to have both anti-glare and ultraviolet light filtering functions at the same time. This allows the thickness of the anti-UV light-transmitting plate to be reduced and the light transmittance to be better. Thus, a relatively low-power light-emitting strip can be used to achieve the required lighting effect, resulting in better lighting effect and relative energy saving.

[0006] According to some embodiments of the present invention, the cross-sections of the diffused light-transmitting plate and the anti-UV light-transmitting plate perpendicular to the first direction are both arc-shaped, and the light-transmitting cover assembly is detachably disposed on the heat dissipation base.

[0007] According to some embodiments of the present invention, the UV-resistant light-transmitting plate is provided with first plug-in blocks on both sides perpendicular to the first direction, the heat sink is provided with two first plug-in slots, the first plug-in slots extend along the first direction, the first plug-in blocks are inserted into the first plug-in slots one by one, and the light strip is placed between the two first plug-in slots.

[0008] According to some embodiments of the present invention, the diffused light-transmitting plate abuts against the side of the anti-UV light-transmitting plate near the light-emitting strip, and the two sides of the diffused light-transmitting plate perpendicular to the first direction abut against the heat sink respectively.

[0009] According to some embodiments of the present invention, the diffused light-transmitting plate is provided with reinforcing ribs on both sides perpendicular to the first direction, and the reinforcing ribs extend along the first direction.

[0010] According to some embodiments of the present invention, the heat sink is provided with two second insertion slots, which are respectively placed on both sides of the lamp strip mounting position. The reflector is configured as reflective paper, and the two sides of the reflective paper perpendicular to the first direction are inserted into the second insertion slots one by one.

[0011] According to some embodiments of the present invention, the light-emitting strip is provided with at least two lamp cores arranged along the first direction, and the reflector is provided with at least two light-transmitting holes arranged along the first direction. The light-transmitting holes correspond one-to-one with the lamp cores, and the lamp cores pass through the corresponding light-transmitting holes.

[0012] According to some embodiments of the present invention, the heat sink is provided with two third insertion slots, the third insertion slots extend along the first direction, and the two sides of the light strip perpendicular to the first direction are inserted into the third insertion slots one by one.

[0013] According to some embodiments of the present invention, the heat sink is provided with heat dissipation through holes, which extend along the first direction and penetrate to both ends of the heat sink.

[0014] According to some embodiments of the present invention, the diffuser plate is configured as a milky white plastic part, and the UV-resistant plate is configured as an orange plastic part.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 4 The energy-saving UV-resistant lamp tube of this utility model embodiment includes a heat sink 100, a light-emitting strip 200, a light-transmitting cover assembly 300, and a reflector 400. The heat sink 100 has a light strip mounting position, and the heat sink 100 is strip-shaped and extends along a first direction. The light-emitting strip 200 is disposed on the heat sink 100, extends along the first direction, and has a light-emitting side. The light-transmitting cover assembly 300 is disposed on the heat sink 100, is strip-shaped and extends along the first direction, and includes a stacked diffuser light-transmitting plate 310 and a UV-resistant light-transmitting plate 320. The light-emitting side of the light-emitting strip 200 faces the light-transmitting cover assembly 300. The reflector 400 is disposed on the heat sink 100, is strip-shaped and extends along the first direction, and has a reflective surface on the side of the reflector 400 facing the light-transmitting cover assembly 300.

[0023] The light emitted by the light strip 200 passes directly through the light-transmitting cover assembly 300, and is also reflected by the reflector 400 before passing through the light-transmitting cover assembly 300. The light-transmitting cover assembly 300 includes a stacked diffuser light-transmitting plate 310 and an anti-UV light-transmitting plate 320. The diffuser light-transmitting plate 310 diffuses and prevents glare from the light emitted by the light strip 200, while the anti-UV light-transmitting plate 320 filters ultraviolet light. By processing the two separately and stacking them to form the light-transmitting cover assembly 300, the anti-UV light-transmitting plate 320 does not need to have both anti-glare and ultraviolet light filtering functions at the same time. This allows the thickness of the anti-UV light-transmitting plate 320 to be reduced and its light transmittance to be better. As a result, a relatively low-power light strip 200 can be used to achieve the required lighting effect, resulting in better lighting effect and relatively energy saving.

[0024] Specifically, the reflector 400 can make full use of the light emitted by the light strip 200, thereby improving the luminous efficacy and illuminance of the lamp tube.

[0025] Reference Figure 2 In this embodiment, both the diffuser plate 310 and the UV-resistant plate 320 have arc-shaped cross-sections perpendicular to the first direction, and the light-transmitting cover assembly 300 is detachably mounted on the heat sink 100. Since both the diffuser plate 310 and the UV-resistant plate 320 have arc-shaped cross-sections, the cross-section of the light-transmitting cover assembly 300 formed by their stacking is also arc-shaped. This results in a larger light-transmitting area, better light transmission, and improved heat dissipation for the light-emitting strip 200.

[0026] Reference Figure 4In this embodiment, the UV-resistant light-transmitting plate 320 has first insertion blocks 321 on both sides perpendicular to the first direction, and the heat sink 100 has two first insertion slots 110 extending along the first direction. The first insertion blocks 321 are inserted into the first insertion slots 110 one by one, and the lamp strip is placed between the two first insertion slots 110. Through the insertion and cooperation of the first insertion blocks 321 and the first insertion slots 110, the diffused light-transmitting plate 310 and the heat sink 100 are detachably connected, the installation structure is simple, and the disassembly and assembly are relatively convenient. It is conceivable that in other embodiments, a first insertion slot 110 may be provided in the diffuser plate 310 and a first insertion block 321 may be provided in the heat sink 100; or the diffuser plate 310 may be detachably installed in the heat sink 100 in other ways, such as providing a slot in the heat sink 100 and a hook in the diffuser plate 310, and the two are detachably connected by the hook engaging with the slot.

[0027] Reference Figure 2 In this embodiment, the diffuser plate 310 abuts against the UV-resistant light-transmitting plate 320 on the side near the light-emitting strip 200, and the two sides of the diffuser plate 310 perpendicular to the first direction abut against the heat sink 100 respectively. The diffuser plate 310 and the UV-resistant light-transmitting plate 320 abut against the side near the light-emitting strip 200, and both ends of the diffuser plate 310 abut against the heat sink 100 respectively. The installation and fixation of the diffuser plate 310 are achieved by limiting the position of the two abutting against each other. The installation method is simple, and the diffuser plate 310 can also be removed simultaneously when the UV-resistant light-transmitting plate 320 is removed.

[0028] Specifically, the light-transmitting cover assembly 300 is detachably mounted to the heat sink 100 via a diffuser light-transmitting plate 310. It is conceivable that in other embodiments, the diffuser light-transmitting plate 310 may also be detachably mounted to the heat sink 100 independently. For example, the diffuser light-transmitting plate 310 may be detachably mounted to the heat sink 100 via a plug-in or snap-fit ​​connection. In this case, the light-transmitting cover assembly 300 is detachably mounted to the heat sink 100 via both the diffuser light-transmitting plate and the UV-resistant light-transmitting plate 320.

[0029] Reference Figure 2 In this embodiment, the light-transmitting diffuser plate 310 is provided with reinforcing ribs 311 on both sides perpendicular to the first direction, and the reinforcing ribs 311 extend along the first direction. The reinforcing ribs 311 make the structural strength of both sides of the light-transmitting diffuser plate 310 high and less prone to cracking.

[0030] Reference Figure 4In this embodiment, the heat sink 100 is provided with two second insertion slots 120, which are located on both sides of the lamp strip mounting position. The reflector 400 is configured as reflective paper, and the two sides of the reflective paper perpendicular to the first direction are inserted into the second insertion slots 120 one by one. The two sides of the reflective paper are inserted into the slots 120, so that the reflective paper is installed on the heat sink 100. The installation structure is simple and not easy to loosen.

[0031] It is conceivable that in other embodiments, the reflective paper may also be installed on the heat sink 100 by means of adhesive, for example, and those skilled in the art may choose according to actual needs.

[0032] It is conceivable that the reflector 400 could also be, for example, a reflector with a reflective coating on its surface, which can be selected by those skilled in the art according to actual needs.

[0033] Reference Figure 3 In this embodiment, the light-emitting strip 200 has at least two lamp cores 210 arranged along a first direction, and the reflector 400 has at least two light-transmitting holes 410 arranged along the first direction. Each light-transmitting hole 410 corresponds to one of the lamp cores 210, and the lamp core 210 passes through the corresponding light-transmitting hole 410. The lamp core 210 can pass through the corresponding light-transmitting hole 410, allowing the edge light emitted by the lamp core 210 to be reflected by the remaining area of ​​the reflective paper and pass through the light-transmitting cover assembly 300, thus achieving a high light reflection utilization rate of the reflective paper.

[0034] Specifically, the light strip 200 can be equipped with two or more LED light cores 210, and the corresponding reflective paper is also equipped with two or more light-transmitting holes 410, with the two corresponding one to one.

[0035] Reference Figure 4 In this embodiment, the heat sink 100 is provided with two third insertion slots 130, which extend along a first direction. The two sides of the light-emitting strip 200 perpendicular to the first direction are inserted into the third insertion slots 130 respectively. The light-emitting strip 200 is installed on the heat sink 100 by inserting its two sides into the third insertion slots 130, which is a simple and relatively secure installation method.

[0036] It is conceivable that in other embodiments, the light strip 200 can also be installed on the heat sink 100 by means of, for example, snap-fit. For example, the heat sink 100 is provided with a hook, and the light strip 200 is provided with a slot. The hook snaps into the slot, so that the light strip 200 is installed on the heat sink 100.

[0037] Reference Figure 2In this embodiment, the heat sink 100 is provided with heat dissipation through holes 140, which extend along a first direction and penetrate to both ends of the heat sink 100. The heat dissipation through holes 140 inside the heat sink 100 significantly increase the contact area between the heat sink 100 and the air, thereby significantly improving the heat dissipation performance of the heat sink 100.

[0038] Specifically, the heat sink 100 is typically made of aluminum or similar materials, which have high thermal conductivity. When the LED strip 200 is in operation, it generates heat, which is then transferred to the heat sink 100 for dissipation.

[0039] In this embodiment, the diffuser plate 310 is configured as a milky white plastic part, and the UV-resistant diffuser plate 320 is configured as an orange plastic part. The milky white plastic part has a relatively high anti-glare effect, can diffuse the passing light, and the light has strong penetration in the milky white diffuser plate 310, that is, good light transmittance and little impact on light intensity; the orange plastic part can block ultraviolet light while allowing other light to pass through, which is beneficial to achieving the function of filtering ultraviolet light.

[0040] Specifically, the diffused light-transmitting plate 310 and the UV-resistant light-transmitting plate 320 can be made of materials such as PVC, PC, or PE, and those skilled in the art can choose according to actual needs.

[0041] Optionally, in some embodiments, the diffused light-transmitting plate 310 may also have the ability to filter ultraviolet light, and may be used in conjunction with the anti-UV light-transmitting plate 320 to further improve the degree of ultraviolet light filtration.

[0042] Specifically, in this embodiment, after the lamp tube, the light-emitting strip 200 and the reflective paper are assembled, they are simultaneously inserted into the heat sink 100 along the first direction. Then, the light-transmitting cover assembly 300 is inserted into the heat sink 100 along the first direction to complete the assembly of the lamp tube.
