Description

Technical Field

[0001] This invention relates to lighting equipment, and more particularly to full-screen strip lights. Background Technology

[0002] Lighting fixtures are ubiquitous in our daily lives, especially full-screen strip lights, which have seen significant development in recent years.

[0003] However, the existing full-screen strip light's sensing and control unit and charging interface are located at both ends of the light fixture, occupying space within the strip light's dimensions. This reduces the light-emitting surface area while maintaining the same overall size, affecting the light's illumination. To maintain the same light-emitting surface area, the full-screen strip light would need to be larger, which is detrimental to miniaturization and limits its application scenarios. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a full-screen strip light that makes the light-emitting surface of the lamp larger.

[0005] One of the objectives of this invention is achieved through the following technical solution:

[0006] A full-screen strip light includes a bracket, a light guide assembly, a light emitter cover, and a sensing and control unit. The light emitter cover is mounted on the bracket and extends from one end of the bracket to the other end. The light guide assembly and the sensing and control unit are mounted between the light emitter cover and the bracket. The sensing and control unit does not block the light emitted by the light guide assembly towards the light emitter cover.

[0007] Furthermore, the support includes a bottom wall and a side wall, and the sensing and control unit is located on the side wall. By touching the side wall, the sensing and control unit senses changes in bioelectrical parameters, triggering the full-screen strip light to turn on and off.

[0008] Furthermore, the sensing and control unit is a radar sensor, and the sensing and control unit is located between the bracket and the light-emitting cover.

[0009] Furthermore, the sensing range of the radar sensor is less than 5m.

[0010] Furthermore, the full-screen strip light also includes an end cap, which is installed on the bracket and located at the end of the bracket. The end cap includes a cover body and a fixing post, which extends from the cover body and is inserted into and tightly fitted with the bracket. The cover body has a collection groove on the side facing the fixing post, which is located at the edge of the fixing post to collect debris generated during insertion.

[0011] Furthermore, the collection groove surrounds the fixed post.

[0012] Furthermore, the full-screen strip light also includes a charging interface, which is located between the bracket and the light-emitting cover and on one side of the end cover.

[0013] Furthermore, the charging interface is a USB interface, and the end cover is provided with a plug interface, through which the charging interface is connected to an external power source.

[0014] Furthermore, the bracket is provided with a snap-fit ​​groove and a mounting groove, and a pressure strip is formed between the snap-fit ​​groove and the mounting groove. The light-emitting cover includes a snap-fit ​​part and a light-emitting surface, and a light-emitting edge is formed between the snap-fit ​​part and the light-emitting surface. The snap-fit ​​part is installed in the snap-fit ​​groove, and the light-emitting edge contacts the edge of the bracket. The full-screen strip light also includes a light guide component, which is installed in the mounting groove. The pressure strip abuts against the light guide component, and the projection of the pressure strip on the light guide component does not overlap with the projection of the light-emitting surface on the light guide component, so as to prevent the pressure strip from blocking the light emitted by the light guide component to the light-emitting surface and avoid the formation of a black edge on the full-screen strip light.

[0015] Furthermore, the full-screen strip light also includes a light source, the bracket is also provided with a mounting groove, the pressure strip is located at the top of the mounting groove, the light source is installed in the mounting groove, and the pressure strip is located on one side of the light source to prevent the light source from detaching from the mounting groove.

[0016] Compared to existing technologies, the light-emitting cover of the full-screen strip light of this invention is mounted on the bracket and extends from one end of the bracket to the other. The sensing and control unit is located on the side of the full-screen strip light or between the bracket and the light-emitting cover, realizing a full-screen design for the strip light, increasing the light-emitting surface, improving the lighting effect, or enabling the lamp to be miniaturized. The end cap has a collection groove on the side facing the fixing post, located at the edge of the fixing post to collect debris generated during insertion. The projection of the pressure strip on the light guide assembly does not overlap with the projection of the light-emitting surface on the light guide assembly, preventing the pressure strip from blocking the light from the light guide assembly to the light-emitting surface, thus preventing the full-screen strip light from forming a black edge and making the light-emitting surface of the strip light fully bright, increasing the actual light-emitting surface area.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Figures 1 to 6 The first embodiment of the full-screen strip light of the present invention includes a bracket 10, a light guide assembly 20, a light emitter cover 30, an end cover 40, a light source 50, a motherboard 60, a charging interface 70, and a sensing and control unit 80.

[0030] The bracket 10 is made of an opaque material. Specifically, in this embodiment, the bracket 10 is made of metal. The bracket 10 includes a bottom wall 11 and two side walls 12. The two side walls 12 extend from both sides of the bottom wall 11 and are perpendicular to the bottom wall 11. The two side walls 12 are parallel to each other. Each side wall 12 has a snap-fit ​​groove 120, a pressure strip 121, a mounting groove 122, a boss 123, a fixing groove 124, and a receiving groove 125 in sequence from the end away from the bottom wall 11 to the end near the bottom wall 11. The snap-fit ​​groove 120 is used to install the light emitter mask 30. The pressure strip 121 is located between the snap-fit ​​groove 120 and the mounting groove 122. The pressure strip 121 is used to receive the snap-fit ​​portion 31 of the light emitter mask 30 and to press against the light source 50 and the light guide assembly 20, so that the light source 50 and the light guide assembly 20 are positioned. The vertical projection of the end of the pressure strip 121 is further away from the centerline of the bracket 10 than the vertical projection of the upper edge of the snap-fit ​​groove 120 (i.e., the pressure strip 121 is located inside the bottom of the snap-fit ​​groove 120). The mounting groove 122 is used to accommodate the light guide assembly 20. The boss 123 is used to receive the light guide assembly 20. The fixing groove 124 is used to fix the end cap 40. The fixing groove 124 is arc-shaped. The receiving groove 125 is located on one side of the mounting groove 122 and the boss 123, and below the pressure strip 121. The receiving groove 125 communicates with the mounting groove 122. The receiving groove 125 is rectangular.

[0031] The light guide component 20 is made of light guide material. The light guide component 20 is installed in the bracket 10 to guide the light.

[0032] The light emitter 30 is mounted on the bracket 10, and the light guided by the light guide assembly 20 passes through the light emitter 30 to emit a full-screen strip light. The light emitter 30 includes a light emitting surface 32 and a latching portion 31 extending from both sides of the light emitting surface 32. A light emitting edge 320 is formed between the light emitting surface 32 and the latching portion 31.

[0033] The end cap 40 includes a cover body 41, on which a plug-in interface 410 is provided. The plug-in interface 410 is located at the end of the end cap 40 and is used for USB interface plug-in. The end cap 40 is installed at the end of the bracket 10. Specifically, the end cap 40 is tightly fitted with the fixing groove 124 by means of a post or the end cap 40 is fixed to the bracket 10 by means of a nut. When the end cap 40 is fixed by means of a tight fit between the post and the fixing groove 124, since the end cap 40 is made of plastic and the bracket 10 is made of metal, debris will be generated from the end cap 40 during the tight assembly process. The cover body 41 is provided with a collection groove 411, which surrounds the post to collect the debris generated during the installation process, preventing debris from splashing and getting stuck between the end cap 40 and the bracket 10, creating a gap between the end cap 40 and the bracket 10, resulting in a loose installation and poor sealing.

[0034] The light source 50 is mounted on the side wall 12 inside the bracket 10. Specifically, the light source 50 is mounted in the receiving groove 125, facing the light guide assembly 20, and the light emitted by the light source 50 is transmitted along the light guide assembly 20. Specifically, in this embodiment, the light source 50 is an LED light source.

[0035] The mainboard 60 is mounted on the bottom wall 11 of the bracket 10, located in the cavity between the light guide assembly 20 and the bracket 10. The mainboard 60 is used to control the operation of the light source 50.

[0036] The charging port 70 is mounted on the motherboard 60 and located at the end of the bracket 10. In this embodiment, the charging port 70 is a USB port. The USB port is connected to an external power source through the connector 410 of the end cover 40 to provide power.

[0037] The sensing control unit 80 is installed in the cavity between the side wall 12 of the strip light or the light guide assembly 20 and the bottom wall 11. When the sensing control unit 80 is installed in the side wall 12 of the strip light, it functions as a touch controller. When a person touches the side wall 12, the sensing control unit 80 detects changes in bioelectrical parameters, triggering the strip light to turn on and off. When the sensing control unit 80 is located in the cavity between the light guide assembly 20 and the bottom wall 11, it functions as a radar sensor. The radar sensor's sensing range is less than 5 meters to prevent frequent on / off switching of the light due to an excessively large sensing range. Specifically, the sensing range of the radar sensor can be configured to 1-3 meters, which not only matches the appropriate range of light source illumination but also avoids untimely sensing due to an excessively small range, thus reducing the user experience.

[0038] When assembling the full-screen strip light, the motherboard 60 is mounted on the bottom wall 11 of the bracket 10, located in the cavity between the light guide assembly 20 and the bracket 10. The charging interface 70 is mounted on the motherboard 60 and located at the end of the bracket 10, connected to an external power source via the connector 410 of the end cover 40 for power supply. The sensing and control unit 80 is mounted on the side of the strip light or in the cavity between the light guide assembly 20 and the bottom wall 11. The light source 50 is mounted in the receiving slot 125. The light guide assembly 20 is mounted on two protrusions 123 with its side located in the mounting slot 122. At this time, the light source 50 faces the light guide assembly 20, and the light emitted by the light source 50 is transmitted along the light guide assembly 20. The latching part 31 of the light emitter 30 is mounted in the latching slot 120. At this time, the projection of the light-emitting edge 320 on the light guide component 20 does not overlap with the projection of the pressure strip 121 on the light guide component 20, preventing the pressure strip 121 from blocking the light emitted by the light guide component 20 onto the light-emitting surface 32 and avoiding the formation of black edges on the full-screen strip light.

[0039] Through the above design, the strip light is a full-screen design. The light-emitting cover 30 is installed on the bracket 10 and extends from one end of the bracket 10 to the other end. The sensing and control unit 80 is located on the side of the full-screen strip light or between the bracket 10 and the light-emitting cover 30, realizing the full-screen design of the strip light, making the light-emitting surface 32 larger, making the lighting effect better or the lamp can be miniaturized. The end cover 40 has a collection groove 411 on the side of the cover 41 facing the fixing post 42. The collection groove 411 is located at the edge of the fixing post 42 to collect the debris generated during the insertion. The projection of the pressure strip 121 on the light guide assembly 20 does not overlap with the projection of the light-emitting surface 32 on the light guide assembly 20, preventing the pressure strip 121 from blocking the light from the light guide assembly 20 to the light-emitting surface 32, causing the full-screen strip light to form a black edge, making the light-emitting surface 32 of the strip light fully bright, and increasing the actual area of ​​the light-emitting surface 32.

[0040] Please continue reading. Figure 7 and Figure 8This is a second embodiment of the full-screen strip light of the present invention. In the second embodiment, the structure of the full-screen strip light is the same as that of the first embodiment, except that the shapes of the fixing groove 124 and the receiving groove 125 of the side wall 12 are different. In the second embodiment, the receiving groove 125 is arc-shaped, and the fixing groove 124 is E-shaped. In the second embodiment, the end cap 40 has a different structure from that of the first embodiment. Specifically, the end cap 40 includes a cover body 41, fixing posts 42 extending from the cover body 41, and a mounting bracket 43. The fixing posts 42 are perpendicular to the cover body 41 and are used to fit tightly with the bracket 10. The mounting bracket 43 extends from the cover body 41 and is perpendicular to the cover body 41. There are two fixing posts 42, which are located at the two ends of the cover body 41, and the mounting bracket 43 is located between the two fixing posts 42. The cover body 41 is provided with an insertion interface 410 and a collection groove 411 is provided on the side of the cover body 41 facing the fixing posts 42. The number of collection grooves 411 is the same as the number of fixing posts 42. The collection groove 411 is a recessed structure surrounding the fixing post 42. Specifically, the collection groove 411 extends from the bottom of the fixing post 42. Each fixing post 42 includes a first post 420 and a second post 421. The shape of the first post 420 corresponds to the shape of the fixing groove 124. The cross-section of the first post 420 is U-shaped. The shape of the second post 421 corresponds to the shape of the receiving groove 125. The cross-section of the second post 421 is arc-shaped. The mounting bracket 43 is provided with an opening 430 for installing the charging interface 70. With the above design, the first post 420 of the end cap 40 is inserted into the fixing groove 124, and the second post 421 is inserted into the receiving groove 125. Debris generated by the tight fit of the first post 420 and the second post 421 falls into the collection groove 411, preventing debris from splashing and getting stuck between the end cap 40 and the bracket 10, creating a gap between the end cap 40 and the bracket 10, resulting in a loose installation and poor sealing.

[0041] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
