Technical Field
[0001] This utility model relates to the technical field of linear lamps, and more specifically to a linear lamp fixture. Background Technology
[0002] With technological advancements, people's demands for lighting methods and effects are gradually increasing, requiring different special lighting effects (color temperature, brightness, etc.) for different occasions and locations. Linear lights are commonly used and relatively common lighting fixtures in daily life, but their function is relatively limited. Traditional linear lights have fixed color temperature and wattage, and changing the color temperature or adjusting the brightness requires replacing the entire fixture, which is limiting and gradually fails to meet people's needs for varied lighting. If users want to achieve applications in various scenarios, they need to purchase linear lights with different wattages and beam angles, resulting in a large inventory requirement and significantly increasing capital and warehousing costs.

[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0038] See Figures 1 to 6 The following is an assembly diagram of two embodiments of this utility model, including: a back cover 1, a lamp profile 2, a light source board 3, optical accessories, a left cover 5, a right cover 6, a color temperature switch 7, a brightness adjustment knob 8, and a track head 9.
[0039] The light source board 3 is installed in the lamp profile 2. The rear cover 1 is fixed to the upper end of the lamp profile 2. The color temperature toggle switch 7 is connected to the light source board 3 and installed on the lamp profile 2. The brightness adjustment knob 8 is also electrically connected to the light source board 3. The brightness adjustment knob 8 and the track head 9 can be fixed to the left cover 5 or the right cover 6 at the same time. The side cover on the other side, which is not fixed to the brightness adjustment knob 8 and the track head 9, is provided with a buckle for fixing the linear lamp to the track. The left cover 5 and the right cover 6 are fixedly locked at the left and right ends of the lamp profile 2. The optical accessories can be anti-glare grille lenses 41 or diffuser plates 42. The optical accessories are installed in the lamp profile 2 and are located below the light source board 3.
[0040] In the above embodiments, both color temperature and brightness can be adjusted via the brightness adjustment knob 8 and the color temperature toggle switch 7. The linear lamp has multiple color temperatures and multiple light intensities, making it flexible and suitable for various occasions, and can reduce the user's inventory costs.
[0041] exist Figure 1 , Figure 3 , Figure 5 The first embodiment of this utility model is shown below. In this example, an anti-glare grille lens 41 is used as an optical accessory. The beam angle of the anti-glare grille lens 41 includes 20D, 24D, 40D, 60D, and 80D. Figure 2 , Figure 4 , Figure 6 In the second embodiment of this utility model, a diffuser plate 42 is used as an optical accessory. In this second embodiment, the diffuser plate 42 works in conjunction with PET microstructure reflective paper 421. Two lower slots 23 are provided on the inner walls of the lower sides of the lamp profile 2, and two upper slots 24 are provided on the two sides of the light source plate. The upper and lower ends of the two PET microstructure reflective papers 421 are respectively sandwiched in the upper slots 24 and lower slots 23. The two PET microstructure reflective papers 421 are obliquely arranged in the lamp profile 2, forming a trapezoidal light-guiding space with the light source plate 3 and the diffuser plate 42, thereby further improving the light efficiency. Because the linear lamp structures of the first and second embodiments are simple and easy to assemble, manufacturers can easily produce linear lamps with different types, specifications, and sizes of optical accessories. Users can choose linear lamps with suitable optical accessories according to their needs. Furthermore, in different embodiments of this utility model, users are not limited to the anti-glare grille lens 41 and the diffuser plate 42, but can select and assemble suitable different types of optical accessories and suitable specifications and sizes according to actual usage requirements.
[0042] See Figures 15 to 18 To broaden the application scenarios of linear luminaires and make them more flexible, the linear luminaires in the first and second embodiments may further include a polarizing film 10. The polarizing film 10 is detachably mounted on the light-emitting surface of the optical accessories and is located below the optical accessories. The polarizing film 10 can be selected as a single polarizing film 10 or a double polarizing film 10 depending on the specific situation, so that the light emitted by the linear luminaire has a single polarized or double polarized effect (refer to the situation of light illuminating the left and right walls A in the figure). Users can directly insert the single polarizing film 10 or the double polarizing film 10 into the original linear luminaire to use with the optical accessories according to different application scenarios, thereby adjusting the light emission angle without replacing the new linear luminaire.
[0043] The shielding angle of conventional lighting fixtures is set to greater than 30° based on the normal eye level angle, which prevents direct light from entering the eyes and causing glare. (See also...) Figure 9 In the first embodiment, when the anti-glare grille lens 41 is used in conjunction with the polarizing film 10, the anti-glare grille lens 41 enables the linear luminaire to have a 57° shielding angle, resulting in a better glare reduction effect. (See also...) Figure 10 In the second embodiment, when PET microstructure reflective paper 421 is used in conjunction with diffuser plate 42 and polarizing film 10, it increases luminous efficiency. Therefore, the optical accessories enable linear luminaires to provide both illumination and comfort.
[0044] Further reading Figure 7 , Figure 8 The two embodiments described above also include a driver 11, which is mounted on the rear cover 1 plate. Two press-fit studs are fixedly provided on the lower surface of the rear cover 1 plate, and the driver 11 can be fixed to the lower surface of the rear cover 1 plate by the press-fit studs. In this way, not only is the driver 11 fixed to the rear cover 1 plate, but the driver 11 is also prevented from directly contacting the lamp profile 2, thereby reducing the temperature of the driver 11 and extending its lifespan.
[0045] For ease of assembly, please refer to Figure 11 , Figure 12 In the above embodiment, the brightness adjustment knob 8 is assembled on the right cover 6 by screws and nuts. The brightness adjustment knob 8 extends out of the right cover 6. The user can adjust the brightness of the linear lamp by rotating the knob left and right. Preferably, the brightness adjustment knob 8 can adjust the brightness from 0% to 100%.
[0046] Further reading Figure 13 , Figure 14The upper edge of the lamp profile 2 has a track groove 21 for mounting the rear cover 1. The rear cover 1 slides onto the upper end of the lamp profile 2 via the track groove 21. The lamp profile 2 has an opening groove 22 corresponding to the color temperature toggle switch. The color temperature toggle switch 7 can be assembled onto the opening groove 22 on the lamp profile 2 via a switch fixing plate 71. Preferably, the opening groove 22 is a straight, strip-shaped opening groove 22, and the toggle switch on the color temperature toggle switch protrudes from the opening groove 22, facilitating the installation of the color temperature toggle switch 7 and its operation. The color temperature toggle switch 7 includes six settings: 2700K, 3000K, 3500K, 4000K, 5000K, and 6500K. During use, the user can adjust the color temperature of the linear lamp by moving the color temperature toggle switch 7 left and right.
[0047] Preferably, the light source board 3 of this utility model is provided with multiple LED beads, each LED bead including 4 SMDs.
[0048] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
