Specific embodiments
[0037] The core of the present utility model lies in disclosing a grid lamp to improve the brightness of the grid lamp and reduce the occurrence of light leakage phenomenon.
[0038] Another core of the present utility model lies in disclosing a vehicle including the above grid lamp.
[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0040] As Figure 2 shown, an embodiment of the present utility model discloses a grid lamp, including a lamp housing 10, a transparent mask 20, a lamp board 30, a light-shielding bracket 40, and a front face skin 50.
[0041] Among them, the transparent mask 20 is connected to the lamp housing 10 to form an installation space. The lamp board 30 is arranged in the installation space, and a plurality of light-emitting elements 31 are arranged on the lamp board 30. The light-emitting elements 31 are preferably LED particles. The light-blocking bracket 40 is connected to the transparent mask 20, and the front face skin 50 is connected to the transparent mask 20. That is, the light emitted by the light-emitting elements 31 is emitted after passing through the transparent mask 20, the light-blocking bracket 40, and the front face skin 50 in sequence. The structural schematic diagram of the front face skin 50 is as Figure 1 shown.
[0042] In order to improve the brightness of the grille lamp and make the light emission more uniform, a light-condensing arc surface 21 and an optical pattern 22 are arranged on the transparent mask 20, as Figure 4 and Figure 9 shown. The setting of the light-condensing arc surface 21 can concentrate the light and improve the light illumination efficiency. The setting of the optical pattern 22 can convert the light diverged by the light-emitting elements 31 into parallel light and emit it, which can reduce the occurrence of light leakage phenomenon.
[0043] In some specific embodiments, the transparent mask 20 is connected to the lamp housing 10 through a connecting piece, and specifically, it can be fixed by means of glue-coated screws.
[0044] For the grille lamp disclosed in the embodiment of the present invention, by arranging the light-condensing arc surface 21 and the optical pattern 22 on the transparent mask 20 to improve the brightness of the grille lamp, the setting of the light-condensing arc surface 21 makes the light emitted by the light-emitting elements 31 more concentrated, which can improve the brightness of the grille lamp. The setting of the optical pattern 22 can convert the light emitted by the light-emitting elements 31 into parallel light and emit it, which can reduce the occurrence of light leakage phenomenon, further improve the light efficiency, and make the light emission more uniform. At the same time, for the grille lamp disclosed in the embodiment of the present invention, compared with the prior art of improving the brightness of the grille lamp by adding reflection parts, the number of parts will not be increased additionally. Therefore, the assembly difficulty of the grille lamp can be reduced, and the cost can be reduced at the same time.
[0045] As Figure 4 shown, the light-condensing arc surface 21 is arranged opposite to the light-emitting elements 31, and the optical pattern 22 is arranged on both sides of the light-condensing arc surface 21. The light-condensing arc surface 21 can gather the direct light of the light-emitting elements 31, and the optical pattern 22 arranged on both sides of the light-condensing arc surface 21 can convert the diverged light of the light-emitting elements 31 into parallel light and emit it, reducing the occurrence of light leakage phenomenon.
[0046] In some specific embodiments, the optical pattern 22 is serrated. Of course, the optical pattern 22 can also be other shapes, such as triangular, square, etc.
[0047] In some specific embodiments, a plurality of light-emitting elements 31 are combined to form a plurality of light-emitting units. For any light-emitting unit, the transparent mask 20 is provided with a corresponding condensing arc surface 21 and an optical pattern 22. It should be noted that a light-emitting unit may include one light-emitting element 31 or may include a plurality of light-emitting elements 31, which can be specifically set according to the actual situation.
[0048] For different light-emitting units, the curvature of the condensing arc surface 21 can be the same or different. It should be noted that the curvature of the condensing arc surface 21 can be specifically determined according to actual needs, such as Figures 5 - 8 shown, Figure 5 the curvature of the condensing arc surface 21 shown is greater than Figure 7 the curvature of the condensing arc surface 21 shown. The greater the curvature, the more focused the light pattern can be, Figure 6 a bright line is shown in the middle of the light-emitting surface; when the curvature is small (straighter), the light on the light-emitting surface is more uniform. The specific light pattern is as shown in Figure 8 shown.
[0049] As Figure 4 shown, the light-blocking bracket 40 is provided with light-emitting holes 42 corresponding to the light-emitting units one by one. The shape of the light-emitting holes 42 can be rectangular, triangular, square or circular, and is not specifically limited. The front fascia skin 50 is provided with a light-emitting surface corresponding to the light-emitting holes 42 one by one, and the light-emitting surface is formed by laser engraving after painting the front fascia skin 50.
[0050] The inventor conducted a design verification on the average brightness of one of the light-emitting surfaces. After setting the condensing arc surface 21 and the optical pattern 22 on the transparent mask 20, the average brightness increased by about 1 time. The original brightness was about 1000 nit, and now it is greater than 2400 nit, and the efficiency increased by about 2.4 times.
[0051] At the same time, the inventor conducted a design verification on the average brightness of the first light-emitting surface 51 and the second light-emitting surface 52 shown in Figure 11 When the transparent mask 20 and the optical pattern 22 were not set, the average brightness of the first light-emitting surface 51 was about 36 cd / ㎡, and the average brightness of the second light-emitting surface 52 was about 1408 cd / ㎡. After adding the condensing arc surface 21 and the optical pattern 22, the average brightness of the first light-emitting surface 51 was about 14.7 cd / ㎡, and the average brightness of the second light-emitting surface 52 was about 1408 cd / ㎡. The light-blocking effect was improved by 2.5 times compared with before. It was 38:1 before, and it is 95:1 after adding the condensing arc surface 21 and the optical pattern 22.
[0052] It can be seen that the setting of the condensing arc surface 21 and the optical pattern 22 can improve the brightness of the grille lamp, improve the light efficiency, and can reduce the occurrence of light leakage phenomenon.
[0053] As Figure 10As shown, a light-shielding side wall 41 is provided on the light-shielding bracket 40. The light-shielding side wall 41 is arranged corresponding to the light-emitting units, that is, any two adjacent light-emitting units are separated by the light-shielding side wall, so as to further reduce the occurrence of light leakage and improve the light efficiency.
[0054] In the grid lamp disclosed in the embodiment of the present utility model, the material of the front skin 50 is preferably PP material (polypropylene), which is resistant to chemical corrosion and has strong heat resistance.
[0055] In addition, the present utility model also discloses a vehicle including the above grid lamp, so it has all the technical effects of the above grid lamp, which will not be elaborated here.
