Description

Technical Field

[0001] The utility model relates to an integrated lamp tube and an LED light tube. Background Art

[0002] LED fluorescent tubes are gradually replacing traditional fluorescent tubes due to their low energy consumption, high light efficiency, long life, and environmental protection. Most of the existing LED fluorescent tube housings are split-type designs, including a metal base and a translucent plastic lampshade, the base is used to hold the light source, and the translucent plastic lampshade covers the light source and is buckled with the metal base; such as the LED fluorescent tube disclosed in Chinese invention patent CN103423627B.

[0003] However, the lamp housing is a split design and needs to be assembled, which has low production efficiency and the lampshade is easily damaged when buckled; in addition, the metal base is relatively expensive. Utility Model Content

[0004] The purpose of the utility model is to propose an integrated lamp tube, comprising a circular tube body, wherein the circular tube body comprises a light-transmitting portion and a light-impermeable portion; the light-transmitting portion and the light-impermeable portion are made of an integrally formed plastic material; the light-impermeable portion is provided with a light source mounting groove extending along the length direction of the circular tube body, and the light source mounting groove has a light outlet facing the light-transmitting portion; the light-transmitting portion is formed above the light-impermeable portion; the inner wall of the light-transmitting portion is provided with an arc segment directly opposite to the light outlet and sawtooth segments respectively located on both sides of the arc segment; the sawtooth segment comprises a plurality of sawtooth units connected end to end; each sawtooth unit is inclined upward so that its tooth tip faces the arc segment.

[0005] The utility model also provides an LED light tube, comprising the above-mentioned integrated light tube, an LED light source and two plugs; the LED light source is installed in the light source installation groove; the two plugs are respectively installed at both ends of the circular tube body.

[0006] The LED light tube of the utility model adopts an integrated light tube, which improves production efficiency by molding materials with different light transmittances into one body, without the need for assembly operations. Moreover, the light-transmitting part and the light-impermeable part of the round tube are both made of plastic, which has low production cost, mature processing technology and is easy to implement; and the plastic material is light, which simultaneously reduces transportation costs.

[0007] In addition, when existing fluorescent tubes emit light, it is easy for the lampshade to be bright in the middle and dark on both sides. The light-transmitting portion of the integrated lamp tube of the utility model is provided with a serrated section, which can regularly diffusely reflect the light of the light source to form uniform light output, avoiding the situation where the light tube is bright in the middle and dark on both sides.

[0013] The present application scheme is further described as follows in conjunction with the accompanying drawings:

[0014] Embodiment 1

[0015] See attached Figure 1-3 An integrated lamp tube includes a circular tube body 100, wherein the circular tube body 100 includes a light-transmitting portion 1 and a light-impermeable portion 2; the light-transmitting portion 1 and the light-impermeable portion 2 are integrally formed of a plastic material. Specifically, the plastic material can be selected from polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), polycarbonate (PC), etc.

[0016] The light-proof part 2 is provided with a light source installation groove 21 extending along the length direction of the circular tube body, and the light source installation groove 21 has a light outlet 22 facing the light-transmitting part 1. Specifically, the light-proof part 2 is formed with two limit arms 23 extending along the length direction of the circular tube body 100, and the limit arms 23 include a bending portion 24. The bending portions 24 of the two limit arms 23 are arranged oppositely, and the space between the two limit arms 23 forms the light source installation groove 21. The light source is installed at the bottom of the light-proof part 2, and has a larger light output angle.

[0017] The light-transmitting portion 1 is formed above the light-impermeable portion 2; the inner wall of the light-transmitting portion 1 is provided with a curved surface segment 11 directly opposite to the light outlet 22 and sawtooth segments 12 respectively located on both sides of the curved surface segment 11; the sawtooth segment 12 includes a plurality of sawtooth units 120 connected end to end; each sawtooth unit 120 is tilted upward so that its tooth tip 123 faces the curved surface segment 11.

[0018] The LED light tube of the technical solution adopts an integrated light tube, which improves production efficiency by molding materials with different light transmittances into one body, without the need for assembly operations. The light-transmitting part 1 and the opaque part 2 of the circular tube body 100 are both made of plastic, which has low production costs, mature processing technology and is easy to implement; and the plastic material is light, which simultaneously reduces transportation costs.

[0019] In addition, when existing fluorescent tubes emit light, it is easy for the lampshade to be bright in the middle and dark on both sides. The light-transmitting portion 1 of the integrated lamp tube of the utility model is provided with a serrated section 12, which can regularly diffusely reflect the light of the light source to form uniform light output, thereby avoiding the situation where the light tube is bright in the middle and dark on both sides.

[0020] Each sawtooth unit 120 includes a lower side portion 122 and an upper side portion 121; the upper side portion 121 of the sawtooth unit 120 is located above the lower side portion 122, and one end of the upper side portion 121 and the lower side portion 122 intersect to form a tooth tip 123. The lower side portion 122 of each sawtooth unit 120 is a convex arc surface and faces the light outlet 22; the upper side portion 121 of each sawtooth unit 120 is a concave arc surface and faces the arc surface segment 11.

[0021] The lower edge 122 and the upper edge 121 of the sawtooth unit 120 of the present technical solution are arc surfaces, which increase the reflection direction of the reflection surface area and form a more uniform light output effect.

[0022] The cross-sectional area of ​​the light-transmitting portion 1 is larger than that of the light-impermeable portion 2 ; the light source installation groove 21 is arranged at the inner side of the bottom of the light-impermeable portion 2 .

[0023] The central angle α of the light-transmitting portion 1 is 240-270°; the central angle of the arc segment 11β is 80-85°; and the central angle γ of the sawtooth segment 12 is 80-92.5°.

[0024] In order to facilitate the installation of the lampshade and the light source, the base of the existing lamp tube housing usually needs to occupy one-half of the housing, resulting in a limited light transmission area of ​​the lampshade and a light output angle limited to 180°.

[0025] The light-transmitting portion 1 of the present technical solution is directly formed on the light-impermeable portion 2, and the cross-sectional area of ​​the light-transmitting portion 1 can be larger than that of the light-impermeable portion 2. The central angle of the light-transmitting portion 1 can reach 240°-270°, which is not less than two-thirds of the circular tube body 100, thereby expanding the light output angle and improving the light efficiency.

[0028] The LED light source 200 is a long strip-shaped light board.

[0029] The plug 300 has an inner cavity 310 for inserting the end of the circular tube 100 ; the two ends of the circular tube 100 are respectively inserted into the two plugs 300 .

[0030] The plug 300 is provided with a power connection electrode 400 , and the power connection electrode 400 is located in the extension direction of the light source installation groove 21 , so as to facilitate the power connection of the LED light source 200 .
