Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to an ultra-narrow edge background lamp. Background Art

[0002] Many background lights currently on the market have large shadows on their edges and large margins on their profiles. This means that when two identical background lights are put together, a large shadow will appear. Furthermore, to prevent visible light spots and light leakage on the light-entering edges, common background lights on the market often have very wide margins on the profiles on the light-entering edges, or use very thick light guide plates. This results in a large dark area when looking straight ahead at the background light. Because of the large margins, the overall thickness of the background light will also be very large. Using a thick light guide plate will also be very expensive and heavy.

[0003] To prevent visible light spots and light leakage, profiles with large margins are often used, which will increase dark areas. If the thickness of the light guide plate is simply increased, the cost of the backlight will be extremely high and the overall thickness will also increase. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an ultra-narrow edge background light. The background light of the utility model comprises a profile with an extremely narrow edge and a diffuser plate with a specific structure. The combination of the two can reduce the dark area of ​​the background light so that multiple pieces can be used together without particularly obvious dark areas.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the embodiment of the present utility model is:

[0006] An ultra-narrow edge background light, comprising a profile, a diffuser plate, a light guide plate and an LED light strip, wherein the diffuser plate is arranged above the light guide plate, and the profile is arranged on the sides of the diffuser plate and the light guide plate;

[0007] The profile is integrally formed and comprises a horizontal plate and a vertical plate connected to one end of the horizontal plate, wherein the horizontal plate divides the vertical plate into an upper portion and a lower portion;

[0008] The upper portion of the vertical plate is provided with a first slot plate and a second slot plate in sequence from top to bottom, a first slot is formed between the first slot plate and the second slot plate, and a second slot is formed between the second slot plate and the upper surface of the horizontal plate;

[0009] The end of the light guide plate is arranged in the second groove, the LED light strip is arranged between the end of the light guide plate and the vertical plate, and the LED light strip is arranged in the second groove;

[0010] A portion of the end portion of the diffusion plate is disposed in the first groove, and another portion is disposed in the second groove.

[0011] Furthermore, the width L1 of the first slot plate is smaller than the width L2 of the second slot plate, and the width of the second slot plate is larger than the thickness L0 of the LED light strip;

[0012] The width of the first slot plate is 0.5 mm ≤ L1 ≤ 4 mm.

[0013] Furthermore, the thickness of the first trough plate and the thickness of the connection portion between the first trough plate and the second trough plate are smaller than the thickness of the remaining portion of the profile.

[0014] Furthermore, the lower surface of the horizontal plate is sequentially provided with a third groove, a fourth groove and a fifth groove, wherein the third groove and the fourth groove are circular opening grooves, which cooperate with bolts to connect the profiles provided on the side edges of the diffuser plate and the light guide plate into a whole;

[0015] The fifth slot is a rectangular opening slot for installing a supporting component.

[0016] Furthermore, the third slot is arranged close to the vertical plate, the opening size of the fifth slot is smaller than the inner size thereof, and the opening of the fifth slot is on the same plane as the end of the horizontal plate away from the vertical plate.

[0017] Furthermore, the diffuser plate includes an upper portion and a lower portion, the upper portion has a uniform width, the lower portion has a smaller width than the upper portion, and the lower portion is provided with an inwardly concave V-shaped groove;

[0018] An upper end portion of the diffusion plate is located in the first groove, and a lower end portion of the diffusion plate is located in the second groove and a transition portion between the first groove and the second groove.

[0019] The beneficial effects of the technical solution provided by the embodiment of the utility model are:

[0020] The margins of this new backlight can be as small as 0.5mm-4mm, and there will be no light spots or light leakage. Multiple pieces can be spliced ​​together to achieve excellent results, solving the problem of large dark areas in conventional backlights. Compared with conventional profiles, this new profile has a first slot plate and a second slot plate. The width of the first slot plate is smaller than the width of the second slot plate. This allows the second slot plate to form a raised structure to block the light, rather than simply installing a light strip to clamp the diffuser. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] like Figure 1-3 As shown, an ultra-narrow edge background light includes a profile 1, a diffuser plate 2, a light guide plate 3 and an LED light strip 4. The diffuser plate 2 is arranged above the light guide plate 3, and the profile 1 is arranged on the sides of the diffuser plate 2 and the light guide plate 3.

[0032] like Figure 4 As shown, the profile 1 is integrally formed and includes a horizontal plate 11 and a vertical plate 12 connected to one end of the horizontal plate 11. The horizontal plate 11 divides the vertical plate 12 into upper and lower parts.

[0033] The upper portion of the vertical plate 12 is provided with a first slot plate 13 and a second slot plate 14 in sequence from top to bottom. A first slot 15 is formed between the first slot plate 13 and the second slot plate 14, and a second slot 16 is formed between the second slot plate 14 and the upper surface of the horizontal plate 11.

[0034] The end of the light guide plate 3 is arranged in the second groove 16 , and an LED light strip 4 is arranged between the end of the light guide plate 3 and the vertical plate 12 , and the LED light strip 4 is arranged in the second groove 16 ;

[0035] A portion of the end portion of the diffuser plate 2 is disposed in the first groove 15 , and the other portion is disposed in the second groove 16 .

[0036] The width L1 of the first slot plate 13 is smaller than the width L2 of the second slot plate 14 , and the width of the second slot plate 14 is greater than the thickness L0 of the LED light strip;

[0037] The width of the first groove plate 13 is 0.5 mm ≤ L1 ≤ 4 mm.

[0038] Specifically, as an embodiment, the width L1 of the first slot plate 13 is 2.5 mm.

[0039] The thickness of the first groove plate 13 and the thickness of the connection portion between the first groove plate 13 and the second groove plate 14 are smaller than the thickness of the remaining portion of the profile 1 .

[0040] Specifically, as an embodiment, the thickness of the first slot plate 13 is 0.8 mm.

[0041] The lower surface of the horizontal plate 11 is provided with a third groove 17, a fourth groove 18, and a fifth groove 19 in sequence. The third groove 17 and the fourth groove 18 are circular opening grooves that cooperate with bolts to connect the profile 1 provided on the side edges of the diffuser plate 2 and the light guide plate 3 into a whole.

[0042] The fifth slot 19 is a rectangular opening slot for mounting a supporting component.

[0043] The third slot 17 is disposed close to the vertical plate 12 . The opening size of the fifth slot 19 is smaller than the inner size thereof. The opening of the fifth slot 19 and the end of the horizontal plate 11 away from the vertical plate 12 are in the same plane.

[0044] like Figure 5 and 6 As shown, the diffuser plate 2 includes an upper portion and a lower portion, the width of the upper portion is the same, the width of the lower portion is smaller than the width of the upper portion, and the lower portion is provided with a concave V-shaped groove 21;
