Description

Technical Field

[0001] The utility model relates to the technical field of exhibit lighting, in particular to an exhibition lighting lamp. Background Art

[0002] Exhibition lighting refers to lamps used to provide lighting in exhibitions, exhibition halls or exhibition venues. These lamps are designed to illuminate exhibits or displays to highlight their characteristics, beauty or importance.

[0003] There are many kinds of lighting for exhibits, including spotlights, chandeliers, showcase lights, projection lights, etc. In the exhibition hall, in order to show the prominence of the exhibits, the light in the scene is often dim. The exhibits are illuminated on the surface by lighting, so as to clearly show the appearance of the exhibits.

[0004] Existing lighting lamps are often installed in a fixed position to shine light directly on the exhibits. Due to the contrast between the bright light and the surrounding dim environment, the exhibits are clearly visible on the illuminated side, but shadows are likely to exist on the backlit side. People's viewing or camera framing are often at multiple angles. When the observation angle is inconsistent with the light irradiation angle, it is easy to see the shadow area, which can easily reduce the display effect of the exhibits. Existing lighting lamps are also installed at multiple angles for illumination, but for some exhibits that often appear irregular in shape, long or wide, or have protrusions or depressions, the superposition and uneven distribution of light can easily cause the phenomenon of light and shadow interlacing, forming light spots, which can still easily affect the display effect of the exhibits.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1-Figure 5 A display lighting lamp includes a display stand 1 and an exhibition cover 2 on the upper side of the display stand 1. The upper surface of the display stand 1 is provided with a base 11 for placing exhibits. The upper surface of the display stand 1 and the outer side of the base 11 are provided with a lighting mechanism 3, and another lighting mechanism 3 is invertedly provided on the top of the inner side of the exhibition cover 2.

[0026] The utility model is further described below in conjunction with embodiments.

[0027] The lighting mechanism 3 includes an annular light frame cover 31 arranged on the outside of the base 11. The cross-section of the annular light frame cover 31 is triangular, and the side close to the base 11 is an upward, hollow slope, on which an elastic soft light cloth 32 is laid, and an adjustment ring 34 is suspended near the bottom of the slope, and a plurality of electric push rods 341 for supporting the adjustment ring 34 are provided on the lower side of the adjustment ring 34. The adjustment ring 34 is fixedly connected to the lower side of the elastic soft light cloth 32, and an elastic shading cloth 33 is also connected to the lower edge of the hollow slope of the annular light frame cover 31. The inner wall of the annular light frame cover 31 is provided with a plurality of annular ring light belts 35, and the surface of the annular light belts 35 is provided with lamp beads 351.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the lamp beads 351 in the annular light frame cover 31 emit bright light, and the bright light is irradiated onto the elastic soft light cloth 32, and the elastic soft light cloth 32 converts the direct light of the lamp beads 351 into flexible light, which is evenly irradiated onto the surface of the exhibit placed on the upper side of the base 11. Since the elastic soft light cloth 32 is arranged in a ring shape around the base 11, the light can be evenly sprinkled on the outer surface of the exhibit at the lower side of the exhibit. By setting the upper and lower lighting mechanisms 3, the flexible light can be fully irradiated onto the surface of the exhibit. The generation of shadows is caused by the strength of light in different planes. The light emitted by the lamp beads 351 is softened and evenly processed by the upper and lower lighting mechanisms 3 and the elastic soft light cloth 32, so that the intensity of the light on the irradiated surface of the exhibit is evenly uniform, thereby avoiding the generation of shadows.

[0029] The tilt angle of the elastic soft light cloth 32 can be controlled by synchronously controlling the extension and retraction of multiple electric push rods 341 to control the lifting and lowering of the control adjustment ring 34, thereby controlling the tilt angle of the elastic soft light cloth 32 so that the flexible light emitted by the elastic soft light cloth 32 can directly hit the surface of the exhibit, avoiding inaccurate illumination area.

[0030] In one embodiment, the color of the elastic soft light cloth 32 is white, the color of the elastic light shielding cloth 33 is black, and the lower surface thereof is coated with reflective material.

[0031] The working principle and beneficial effects of the above technical solution are as follows: by setting the elastic soft light cloth 32 to white, the light can be effectively scattered, making the light softer and more uniform, avoiding the generation of overly strong shadows, and the white color will not change the color temperature of the light, thereby maintaining the natural color of the photographic scene. The setting of the elastic shading cloth 33, on the one hand, prevents light from leaking from the elastic shading cloth 33, causing waste of light source and affecting the lighting effect of the elastic soft light cloth 32, and on the other hand, can make the shadow produced by the adjustment ring 34 clear. During the process of controlling the lifting and lowering of the adjustment ring 34, the irradiation area of ​​the elastic soft light cloth 32 can be accurately controlled by observing the shadow.

[0032] In one embodiment, an annular tube 38 is fixedly mounted on the inner bottom surface of the annular light frame cover 31 , a plurality of vent holes 381 are opened on the side of the annular tube 38 , and an air supply pump 382 is provided on the bottom surface of the annular light frame cover 31 and communicated with the annular tube 38 .

[0033] The working principle and beneficial effects of the above technical solution are as follows: by controlling the air supply pump 382, ​​the annular tube 38 is allowed to blow or exhaust air toward the inner side of the annular lamp frame cover 31 through the air vent 381. When exhausting air, the surface of the elastic soft light cloth 32 will be concave. At this time, the light passing through the elastic soft light cloth 32 is easy to focus and concentrate the irradiation area. When gas is blown in, the surface of the elastic soft light cloth 32 will bulge outward in an arc shape. At this time, the light passing through the elastic soft light cloth 32 is easy to disperse, so that the irradiation area can be expanded.

[0034] In one embodiment, the ventilation hole 381 is located away from the elastic diffuser fabric 32 .

[0035] The working principle and beneficial effects of the above technical solution are as follows: since the outer opening of the air vent 381 will generate blowing force or suction force when the annular tube 38 blows or inhales through the air vent 381, by opening it on the side away from the elastic soft light cloth 32, it is possible to avoid the force acting on the surface of the elastic soft light cloth 32 for a long time, thereby causing local unevenness on the surface of the elastic soft light cloth 32 and affecting the lighting effect.

[0036] In one embodiment, a lighting assembly 36 is embedded and installed on the lower surface of the annular light frame cover 31 , an optical fiber line 364 is connected to the lower side of the lighting assembly 36 , and one end of the optical fiber line 364 is connected to the lighting assembly 37 .

[0037] In one embodiment: the lighting component 36 includes a lighting tube 361 embedded in the lower surface of the annular light frame cover 31, a convex lens 362 is arranged on the upper side thereof, and penetrates into the inner side of the annular light frame cover 31, the focal length of the convex lens 362 is located at the end of the optical fiber line 364, and a gate valve 363 is also arranged on the side surface of the lighting tube 361.

[0038] In one embodiment, the lighting assembly 37 includes a focusing tube 371 connected to the optical fiber line 364 , a suction cup 373 is provided on one side of the focusing tube 371 , and a rotating adjustment member 372 is connected between the suction cup 373 and the rotating adjustment member 372 .

[0039] The working principle and beneficial effects of the above technical solution are as follows: the convex lens 362 on the upper side of the light collecting tube 361 is responsible for collecting the light in the annular light frame cover 31 and focusing it on the optical fiber line 364. The amount of light entering can be controlled by adjusting the door valve 363. The optical fiber line 364 transmits the light to the focusing tube 371, and then the focusing tube 371 focuses the light and emits it.

[0040] For areas on exhibits with deep depressions, it is inconvenient for the light emitted by the elastic soft light cloth 32 to directly illuminate the inside. The light beam focused by the focusing tube 371 can be irradiated therein to illuminate the local area so that the exhibits can be fully displayed. The suction cup 373 can be used to absorb and fix the focusing tube 371 on the inner wall of the exhibition cover 2 to fix the position of the focusing tube 371. The rotating adjustment member 372 can be used to adjust the angle of the focusing tube 371 so that the light beam emitted by the focusing tube 371 can illuminate the depressed area.

[0041] In one embodiment: the lower surface of the annular lamp frame cover 31 is also provided with an annular slider 312, the inner side of the annular slider 312 is provided with a sliding annular rail 311, the annular slider 312 is sealingly and slidably connected with the annular rail 311, and the lighting assembly 36 is embedded and installed in the annular slider 312.

[0042] The working principle and beneficial effects of the above technical solution are as follows: by arranging the lighting assembly 36 on the annular slider 312, it is convenient to adjust the position of the lighting assembly 36, so that the position of the lighting assembly 36 can be adaptively adjusted according to the recessed area of ​​the exhibit. It has a simple structure, is easy to use, has a reasonable design, and is highly practical.
