Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a light-type cut-off structure and a wall lamp thereof. Background Art

[0002] The existing wall lamps on the market use LED lamp beads as the light source. The blue light generated by the internal LED chip and the yellow light generated by the phosphor are superimposed to obtain white light. Since the light-emitting area of ​​the phosphor is different from that of the LED chip, the edge of the light beam is not superimposed and is still the yellow light of the phosphor. Therefore, when the light of the wall lamp shines on the wall, yellow light will be generated at the edge of the cut-off light beam, affecting the overall lighting effect. Utility Model Content

[0003] Aiming at the problem that yellow light is generated at the edge of the cutoff light beam of the wall lamp due to the different light-emitting areas of the LED chip and the phosphor in the wall lamp, the utility model proposes a light-type cutoff structure and a wall lamp thereof, which are used to solve the above problem.

[0004] On the first aspect, the present application proposes a light-type cutoff structure, including a shading plate and a light source plate arranged in parallel, wherein LED lamp beads are arranged on the light source plate facing the shading plate, and baffles are arranged on both sides of the LED lamp beads perpendicular to the light source plate, and the baffle, the light source plate and the shading plate form a cavity for accommodating the LED lamp beads. Shading parts are also arranged on both sides of the light-emitting surface of the LED lamp beads, and the shading parts block the light beams emitted from the edges of the LED lamp beads, and shading holes for the light beams in the middle of the LED lamp beads to pass through are formed between the shading parts. The light beams at the edge of the light-emitting surface of the LED lamp beads are blocked by the shading parts, thereby reducing the light-emitting area of ​​the fluorescent powder of the LED lamp beads, thereby eliminating the yellow light at the edge of the LED lamp beads.

[0005] In some specific embodiments, a light homogenizer is further provided in the light shielding hole. With this arrangement, the light beam emitted by the LED lamp bead can be mixed with the help of the light homogenizer, which can improve the quality of the light beam and increase the uniformity of the light beam.

[0006] In some specific embodiments, a lens is further provided on the side of the shading hole away from the light source plate. With this setting, the light beam emitted by the LED lamp bead can be converged with the help of the lens, which not only increases the brightness of the light, but also enhances the directionality of the light beam, makes the edge of the light beam clearer, and enhances the cutoff effect.

[0007] In some specific embodiments, a light exit hole is provided at a position of the shading plate corresponding to the cavity. With this structure, the light beam emitted by the LED lamp bead can pass through the cavity and then leave the interior of the lamp body through the light exit hole.

[0008] In some specific embodiments, the size of the light-emitting hole is larger than the size of the light-shielding hole. With this arrangement, the light beam emitted by the LED lamp bead can be completely emitted from the light-emitting hole after being shielded, thus avoiding secondary shielding.

[0009] According to the second aspect of the utility model, a wall lamp is proposed, comprising the light cutoff structure as described above, and also comprising a lamp body, wherein the upper and lower parts of the lamp body are provided with brackets for mounting a light source board, and the lower part of the lamp body is also provided with a diffusion cover covering a shading plate. With this arrangement, the light emitted from the lower part of the lamp body can be made more uniform and soft with the help of the diffusion cover, thereby achieving a better lighting effect.

[0010] In some specific embodiments, the bracket includes a fixing portion and a light-cutting cavity, the light-cutting cavity has a size adapted to the light source board, and one end of the light-cutting cavity cooperates with the light-shielding plate.

[0011] In some specific embodiments, a driving module and a sensing module are also installed in the lamp body, and the sensing module, the light source board and the driving module are electrically connected.

[0012] In some specific embodiments, the top of the sensing module protrudes from the front of the lamp body, and a hole that adapts to the size of the top of the sensing module is opened on the front of the lamp body. With this structure, the sensing module protruding from the outside of the lamp body can sense whether someone is passing by, so that the light can be automatically turned on when someone passes by.

[0013] In some specific embodiments, a wall-mounted bracket is further provided on the back of the lamp body, and the lamp body can be fixedly mounted on the wall by means of this structure.

[0014] Compared with the prior art, the beneficial effects of this application are:

Because the components of the embodiments can be positioned in several different orientations, directional terms are used for the purpose of illustration and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be adopted in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0024] In the first aspect, the utility model proposes a light-type cutoff structure. Figure 1The schematic diagram of the light cut-off structure according to an embodiment of the utility model is shown. Figure 1 a, Figure 2 A schematic diagram of a light cutoff structure according to another embodiment of the utility model is shown. Figure 1 b. As shown in the figure, the structure includes a light source board 10 and a shading plate 11 arranged in parallel. The light source board 10 is provided with an LED lamp bead 12 facing the shading plate 11. Baffles 13 are arranged on both sides of the LED lamp bead 12 perpendicular to the light source board 10. The baffle 13, the light source board 10 and the shading plate 11 form a cavity for accommodating the LED lamp bead 12. Shading parts 14 are also arranged on both sides of the LED lamp bead 12. Shading holes 15 are formed between the shading parts 14 on both sides. The size of the shading hole 15 is smaller than the size of the LED lamp bead 12, so that the shading part 14 only blocks the light beam emitted from the edge of the light emitting surface of the LED lamp bead 12. The light beam emitted from the middle part of the LED lamp bead 12 passes through the cavity and then emits from the light emitting hole 16 corresponding to the shading plate 11. The light beam emitted by the fluorescent powder at the edge of the LED lamp bead 12 is blocked by the shading part 14, thereby solving the problem of yellow light generated at the edge of the light beam emitted by the LED lamp bead 12.

[0025] In a specific embodiment, a light homogenizer 27 is further provided in the light shielding hole 15. The light homogenizer 27 can mix the light beam entering the light shielding hole 15, thereby eliminating the yellow light at the edge of the LED lamp bead 12 and increasing the uniformity of the light beam.

[0026] In a specific embodiment, a lens 26 is further provided on the side of the shading portion 14 away from the light source board 10. The lens 26 can converge the light beam emitted by the LED lamp bead 12, thereby increasing the brightness of the light and enhancing the directionality of the light beam, making the edge of the light beam clearer and enhancing the cutoff effect.

[0027] In a specific embodiment, the light exit hole 16 can be offset from the light shielding hole 15 , and the lens 26 can be adjusted according to the position of the light exit hole 16 , thereby adjusting the emission angle of the light beam so that the light beam can pass through the light exit hole 16 smoothly.

[0028] In a specific embodiment, the size of the light exit hole 16 is larger than that of the light shielding hole 15. This structure can improve the emission rate of the light beam at the light exit hole 16 and avoid the problem that the light beam is blocked by the light shielding plate again after being blocked by the light shielding portion 14.

The diffusion cover 19 can further make the light emitted from the lower part of the lamp body 17 more uniform and soft, thereby improving the lighting effect.

[0030] In a specific embodiment, a driving module 20 and a sensing module 21 are further provided inside the lamp body 17. The sensing module 21 and the light source board 10 are electrically connected to the driving module 20 respectively, and a hole is opened on the front of the lamp body 17 for the top of the sensing module 21 to protrude. Then, the sensing module 21 is used to sense whether there is someone passing by the front of the lamp body 17, thereby realizing the function of automatically turning on the light when someone passes by.

[0031] In a specific embodiment, the sensing module 21 includes but is not limited to a PIR infrared sensing module.

[0032] In a specific embodiment, a wall-mounted bracket 22 is installed on the back of the lamp body 17 , and a hole is opened on the wall-mounted bracket 22 for fixing the lamp body 17 on the wall.

Figure 3-4 As shown, the bracket 18 includes a fixing portion 23 and a light-cutting cavity 24 . The fixing portion 23 is used to cooperate with the inside of the lamp body 17 , and one end of the light-cutting cavity 24 cooperates with the shading plate 11 .

[0034] Figure 5 FIG. 2 shows a schematic cross-sectional view of an embodiment of the present invention taken along the line AA. Figure 1-5 As shown, the light source board 10 is installed in the light cutting cavity 24 and is fixed by a buckle 25 arranged around the edge of the light source board 10, one end of the light cutting cavity 24 cooperates with the shading plate 11, and a baffle 13 and a shading portion 14 are arranged inside the light cutting cavity 24 corresponding to the position of the LED lamp bead 12, and the inside of the light cutting cavity 24 is divided into a plurality of cavities by the baffle 13, and a corresponding lens 26 can be installed in each cavity according to the position of the shading hole 15 and the light emitting hole 16, so that the light beams emitted by the LED lamp beads 12 in different cavities can pass through the light emitting hole 16 smoothly.

[0035] The utility model mainly solves the problem in the prior art that yellow light is generated at the edge of the cutoff light beam due to the different light-emitting areas of the chip and the phosphor of the LED lamp bead 12. The present application proposes a light-type cutoff structure and a wall lamp thereof, by setting a shading portion 14 on both sides of the light-emitting surface of the LED lamp bead 12, the shading portion 14 can block the light beam emitted by the phosphor at the edge of the LED lamp bead 12, and a shading hole 15 is formed between the shading portions 14, and a light-homogenizing sheet 27 is set in the shading hole 15, and the light beam emitted by the LED lamp bead 12 is further mixed, which can improve the quality of the light beam and increase the uniformity of the light beam. A lens 26 can be set on the side of the shading hole 15 away from the LED lamp bead 12, which can increase the brightness of the light while enhancing the directionality of the light beam, making the edge of the light beam clearer and enhancing the cutoff effect.
