Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lighting device that emits light uniformly. Background Technology
[0002] Current LED strip products typically involve laying LED strips at the bottom of a profile and then mounting a lampshade on top of the LED strips. To achieve uniform light projection, it is necessary to ensure that a large number of LED beads are evenly distributed on the LED strip. Taking a common household LED strip with a specification of 320 beads per meter as an example, the large number and dense arrangement of LED beads increases hardware and processing costs. Furthermore, if some beads are damaged, the lighting effect will be significantly degraded.
[0003] Furthermore, even if patterns are added to the lampshade, it only changes the visual effect of the lampshade. The actual projected light effect does not change substantially. In essence, the light is still emitted uniformly through the entire lampshade, making it difficult to obtain the projected light effect of patterns such as particles and textures. Utility Model Content
[0004] This embodiment discloses a lighting device that emits uniform light, specifically including:
[0005] An LED light panel 200 is assembled in the mounting groove 110 of the profile base 100;
[0006] The surface of the LED light panel 200 is fitted with a reflective film 300 and a light guide plate 400, and the left end cap 500 and the right end cap 600 encapsulate the two ends of the profile base 100;
[0007] The LED light board 200 is provided with LED beads 210 that illuminate the light guide plate 400 and a connecting terminal 220 at both ends;
[0008] The light guide plate 400 is provided with several light guide areas 410.
[0009] As an optional implementation, the LED beads 210 at both ends of the LED light board 200 synchronously illuminate both ends of the light guide plate 400.
[0010] As an optional implementation, the light guide plate 400 has a plurality of light guide areas 410 on its inner wall surface, and the reflective film 300 is attached to the outer wall surface of the back of the light guide plate 400.
[0011] As an optional implementation, the inner wall surface of the light guide plate 400 reflects the light emitted by the LED beads 210, and the light is evenly projected into the interior of the light guide plate 400.
[0012] As an optional implementation, the light guiding area 410 on the inner wall of the light guide plate 400 refracts light, so that the light is emitted uniformly from the front of the light guide plate 400.
[0013] As an optional implementation, several projection patterns are printed on the outer wall surface of the front side of the light guide plate 400.
[0014] As an optional implementation, the bottom of the left plug 500 and the right plug 600 are provided with tenons 510, and the sides are provided with positioning blocks 520.
[0015] A wiring hole 610 is provided at the end of the right plug 600.
[0016] As an optional implementation, the tenon 510 is inserted into the limiting groove 120 of the profile base 100, and the positioning block 520 is placed into the inner walls of both sides of the mounting groove 110 of the profile base 100.
[0017] As an optional implementation, the wiring hole 610 of the right plug 600 is used to lay the power cable connected to the connection terminal 220.
[0018] As an optional implementation, the profile base 100 is externally fitted with a plurality of mounting clips 700, which are used to reassemble the profile base 100 in the installation area.
[0019] Compared with the prior art, this embodiment has the following beneficial effects:
[0020] In this embodiment, LED beads are only placed at both ends of the light guide plate. The light emitted by the LED beads is uniformly projected into the interior of the light guide plate through reflection from the inner wall surface. Then, the light guiding area on the inner wall surface of the light guide plate refracts the light, causing it to be uniformly emitted from the front of the light guide plate. This achieves uniform light effect while significantly reducing hardware and processing costs. In addition, by imprinting projection patterns on the surface of the light guide plate, clear light and shadow effects can be projected. Attached Figure Description

[0028] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] Please see Figures 1-4 This embodiment discloses a uniformly emitting lighting device, comprising:
[0030] The profile base 100 is fitted with an LED light panel 200 in the mounting groove 110 of the profile base 100;
[0031] The surface of the LED light board 200 is fitted with a reflective film 300 and a light guide plate 400, and the left end cap 500 and the right end cap 600 encapsulate the two ends of the profile base 100.
[0032] LED lamp beads 210 that illuminate the light guide plate 400 and connecting terminals 220 are respectively provided at both ends of the LED lamp board 200.
[0033] The light guide plate 400 is provided with several light guiding areas 410.
[0034] Here, the light guide plate 400 uses optical grade acrylic as the substrate, so that the light emitted by the LED beads 210 is evenly projected into the interior of the light guide plate 400 through reflection from the wall surface.
[0035] Furthermore, by rationally configuring the shape, area, and position of the light guide area 410, the light inside the light guide plate 400 is refracted, so that the light is emitted uniformly from the front of the light guide plate 400. Thus, with only two LED beads 210 assembled, the same uniform light projection effect as existing light strip products with hundreds of LED beads 210 is obtained, which greatly reduces hardware and processing costs.
[0036] As an optional implementation, the LED beads 210 at both ends of the LED light board 200 synchronously illuminate both ends of the light guide plate 400.
[0037] As an optional implementation, a plurality of light guiding areas 410 are provided on the inner wall surface of the back of the light guide plate 400, and a reflective film 300 is attached to the outer wall surface of the back of the light guide plate 400.
[0038] Here, the reflective film 300 effectively directs the scattered light onto the front of the light guide plate 400, achieving a light-focusing effect.
[0039] As an optional implementation, the inner wall surface of the light guide plate 400 reflects the light emitted by the LED beads 210, and the light is evenly projected into the interior of the light guide plate 400.
[0040] As an optional implementation, the light guiding area 410 on the inner wall of the light guide plate 400 refracts the light, so that the light is emitted uniformly from the front of the light guide plate 400.
[0041] Specifically, through reflection from the inner wall of the light guide plate 400, the light emitted by the LED beads 210 is uniformly projected inside the light guide plate 400.
[0042] Furthermore, the specifically designed light-guiding area 410 refracts light outwards.
[0043] Understandably, for light guide areas 410 at different distances from the LED beads 210, those closer to the LED beads 210 should have a relatively smaller area; conversely, those farther away should have a relatively larger area. This ensures that light guide areas 410 at different positions project light of the same intensity, achieving uniform light effect.
[0044] As an optional implementation, several projection patterns are printed on the outer wall surface of the front of the light guide plate 400.
[0045] Here, by printing projection patterns on the outer wall of the light guide plate 400, clear and realistic light and shadow effects can be projected, which is significantly better than printing patterns on the lampshade.
[0046] As an optional implementation, the bottom of the left plug 500 and the right plug 600 are provided with tenons 510, and the sides are provided with positioning blocks 520.
[0047] A wiring hole 610 is provided at the end of the right plug 600.
[0048] As an optional implementation, the tenon 510 is inserted into the limiting groove 120 of the profile base 100, and the positioning block 520 is placed into the inner walls of both sides of the mounting groove 110 of the profile base 100.
[0049] As an optional implementation, the wiring hole 610 of the right plug 600 is used to lay the power cable connected to the connection terminal 220.
[0050] As an optional implementation, the profile base 100 is externally fitted with several mounting clips 700, which are used to reassemble the profile base 100 in the installation area.
[0051] Therefore, by fixing and assembling the mounting clip 700 in the installation area, the profile base 100 can be easily snapped into the mounting clip 700.
[0052] Compared with the prior art, this embodiment has the following beneficial effects:
[0053] In this embodiment, LED beads are only placed at both ends of the light guide plate. The light emitted by the LED beads is uniformly projected into the interior of the light guide plate through reflection from the inner wall surface. Then, the light guiding area on the inner wall surface of the light guide plate refracts the light, causing it to be uniformly emitted from the front of the light guide plate. This achieves uniform light effect while significantly reducing hardware and processing costs. In addition, by imprinting projection patterns on the surface of the light guide plate, clear light and shadow effects can be projected.
