[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] like Figures 1 to 3 As shown, this embodiment provides a linear light to prevent light leakage, including a lamp housing 1 and a light-transmitting cover 2. The lamp housing 1 is strip-shaped, and a partition 11 is provided in the middle of the lamp housing 1. An LED light source 3 is installed in the middle of the partition 11. In order to support the LED light source, thermally conductive silicone grease is applied between the partition 11 and the LED light source 3 for heat dissipation. An opening 101 is provided at the top of the lamp housing 1, and the light emitted by the LED light source 3 comes out through the opening 101. Extending edges 102 are provided on both sides of the opening 101 of the lamp housing 1, and the extending edges 102 extend inward. Light-shielding plates 12 are provided on both sides of the LED light source 3. The light-shielding plates 12 extend from the partition plate 11 to the edge 102. A fastening edge 103 is provided on the light-shielding plate 12 near the edge 102. The light-transmitting cover 2 is fastened to the opening 101 by the fastening edge 103. When the lamp housing 1 is connected to the end of the lamp housing 1, a little bit of light from the LED light source passes through the gap. Because most of the light is blocked by the light-shielding plates 12, even if a little bit of light comes out through the gap, it will not exist after the outer shell comes into contact. Therefore, by setting the light-shielding plates 12, the gaps that leak light can be effectively blocked.

[0029] As an optional embodiment, an end cap 5 is installed at the end of the lamp housing 1, and a blocking block 51 is provided on the end cap 5. The blocking block 51 is inserted between the light shield 12 and the side of the lamp housing 1, and the blocking block 51 effectively blocks light from leaking from the side.

[0030] As an optional embodiment, the light-shielding sheets 12 on both sides are tilted to the sides from the position of the partition 11, and the tilt angle can effectively increase the irradiation area.

[0031] In addition, reflectors 15 are provided on both sides of the opening 101 and on the surface of the light shield 12. The reflectors 15 can refract the light of the LED light source 3 onto the light-transmitting cover 2 to improve the light efficiency and achieve a high lumen effect. The reflectors 15 can be pasted on the light shield 12 or extended to the bottom of the LED light source 3 for pressing and fixing.

[0032] As an optional embodiment, the end cap 5 is provided with a crossbar 52, which contacts the light-transmitting cover 2 and is used to support the edge of the light-transmitting cover 2. The crossbar 52 can block light leakage between the end cap 5 and the light-transmitting cover 2 and can support the light-transmitting cover 2 to prevent it from being recessed inward.

[0033] In existing technology, the connection between linear lights, as described in the background section, typically involves inserting several connecting pieces into grooves at the edge of the housing, and then securing them with screws mounted on these connecting pieces. This method is cumbersome and time-consuming. Therefore, as... Figures 4 to 6As shown, a connection method for linear lights is provided. A connecting part 6 is provided between the lamp housing 1 and the lamp housing 1. Slots 13 are provided on both sides of the top of the lamp housing 1, and connecting pieces 7 are installed in the slots 13. The connecting pieces 7 are fixed with screws to prevent the lamp housing 1 from separating from the lamp housing 1. The connecting part 6 connects and fixes the linear lights together. The connecting part 6 includes a connecting female plug 61 and a connecting post 62. The connecting female plug 61 is installed at one end of the linear light and connects to another linear light with the connecting female plug 61 installed. The end of the connecting female plug 61 is installed with the lamp housing 1. The connecting female plug 61 has a groove 611. The two ends of the connecting post 62 are respectively inserted into the groove 611 of the connecting female plug 61. The outer periphery of the female connector 61 is provided with several spring clips 612. The spring clips 612 are designed to secure the female connector 61 and prevent it from falling off. The surface edge of the female connector 61 is provided with a limiting protrusion 613. The lamp housing 1 is provided with a slot 14 corresponding to the limiting protrusion 613. The limiting protrusion 613 is inserted into the slot 14, so that the female connector 61 is flush with the end of the lamp housing 1. The female connector 61 will be inserted into the end position of the lamp housing 1 and fixed by the outer spring clips 612. When inserted into the lamp housing 1, the limiting protrusion 613 will limit the female connector 61 from extending too deeply and prevent the female connector 61 from falling into the depth of the outer housing 1. The connection is made by the connecting part 6 and the connecting piece 7 is used to prevent separation. This structure is simple to install and the installation speed is fast.

[0034] In addition, the connecting female plug 61 is embedded into the end of the lamp housing 1 so that the surface is flush. When the lamp housing 1 is connected to the lamp housing 1, the end face of the lamp housing 1 fits together due to the flush surface, so as to achieve a seamless connection and prevent light leakage.

[0035] As an optional embodiment, the groove 611 of the connecting female plug 61 is provided with a first through hole 614, and the connecting post 62 is provided with a second through hole 621. The first through hole 614 and the second through hole 621 can be used for the passage of wires. The four corners of the connecting post 62 are chamfered for easier installation.

[0036] As an optional embodiment, a power driver is provided inside the lamp housing 1, and the power driver is connected to the LED light source 3. A third through hole 104 is provided on the lamp housing 1, and a terminal block 16 is provided inside the third through hole 104. The lamp housing 1 and the terminal block 16 are fixed together by a fixing bracket 17. The terminal block 16 is installed in the central groove of the fixing bracket 17, and both ends of the fixing bracket 17 are fixed to the lamp housing 1. A dust cover is installed on the third through hole 104. The terminal block 16 is electrically connected to the power driver, and the other end of the terminal block 16 is connected to the outside. The power supply driver extends a segmented wire, which passes through the first through hole 614 and the second through hole 621 to connect to the LED light source 3 at the other end. When a single linear light is started, the end caps 5 are inserted at both ends, and the external wire is connected to the terminal block 16 to start the LED light source 3. If two linear lights need to be connected together, the terminal block 16 of the first linear light is connected to the external wire, and then the power supply driver extends a segmented wire. The segmented wire passes through the first through hole 614 and the second through hole 621 to connect to the LED light source of the other linear light. This method is convenient to install and simple to wire.

[0037] In addition, a color temperature adjustment switch is installed on the lamp housing 1. The LED light source is divided into a first color temperature light source and a second color temperature light source. The color temperature adjustment switch is connected to the LED light source 3 and switches between the first color temperature light source and the second color temperature light source. The first color temperature light source is white light, and the second color temperature light source is yellow light. The color temperature adjustment switch can be used to switch between yellow light and white light, or to turn on both yellow light and white light.

[0038] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
