The atmosphere lamp and the display device in the embodiment of the present invention will now be described.

Referring to fig. 1 and 2, the display device described in this embodiment includes a housing 10 and any one of the atmosphere lamps described below.

Referring to fig. 3 to 5, the atmosphere lamp includes a lamp housing 100 and a light source assembly 200. The lamp housing 100 includes a light blocking member 110 and a light transmitting member 120. The light blocking member 110 has a light exit hole 111, the light transmitting member 120 is installed on the light entrance side of the light blocking member 110 and covers the light exit hole 111, and the light transmitting member 120 can scatter light incident therein and output scattered light to the light exit hole 111, so that the light passing through the light transmitting member 120 becomes uniform and soft, and the occurrence of lamp shadows is reduced.

Specifically, referring to fig. 4, the light-transmitting element 120 has a light incident surface 121 and a light emitting surface 122 disposed opposite to each other. The light emitting surface 122 is located on one side of the light incident surface 121 close to the light blocking member 110, and the light emitting surface 122 is used for scattering light.

Specifically, the light-transmitting member 120 may use a colloid material having a certain viscosity as a matrix, and the transmittance is greater than 60%, so that light can smoothly transmit through the light-transmitting member 120. Meanwhile, scattering particles are doped in the host colloidal material, so that light incident to the scattering particles is scattered, and scattered light in various directions is generated.

In some embodiments, the light-transmissive member 120 is a piece of polymethyl methacrylate, polycarbonate, or ground glass.

In some embodiments, the light emitting surface 122 of the light-transmissive member 120 is a rough surface to diffuse light, so that the light-transmissive member 120 only transmits light but cannot transmit light.

In some embodiments, the light-transmitting member 120 seals the light-emitting hole 111, so as to prevent a gap from occurring between the light-transmitting member 120 and the edge of the light-emitting hole 111, thereby avoiding a lamp shadow from occurring due to light leakage from the gap, and facilitating improvement of a rendering effect.

Alternatively, the light-transmitting member 120 is formed on the light blocking member 110 by two-shot molding. In other words, the light blocking member 110 is formed by molding the opaque plastic material in a primary plastic mold, and then the light blocking member 110 is taken out after molding and placed in a secondary mold to be injected with the transparent plastic material again, so as to form the light transmitting member 120.

Alternatively, the light-transmitting member 120 is formed on the light blocking member 110 by two-color injection molding. In other words, the opaque plastic material and the transparent plastic material are injected into the same mold, so as to obtain the lamp housing 100 by one-step injection molding. The lamp housing 100 includes a light blocking member 110 and a light transmitting member 120.

Therefore, the light-transmitting member 120 is formed on the light blocking member 110 by adopting a secondary injection molding process or a double-color injection molding process, the light-transmitting member 120 and the light blocking member 110 are stably installed, and compared with a glue bonding operation, the bonding process is saved, and the manufacturing cost is reduced. Simultaneously, light-transmitting member 120 can cover light-emitting hole 111 better, compares and adopts glue to bond, prevents to appear the gap between light-transmitting member 120 and the edge of light-emitting hole 111, prevents to lead to the lamp shadow to appear because of the light leak, is favorable to improving and renders up the effect.

In this embodiment, the shape, position, number and distribution relationship of the light exit holes 111 of the light blocking member 110, and the shape of the light blocking member 110 may be flexibly set according to the appearance modeling and the assembly requirement, which are not limited herein.

In the present embodiment, the light source assembly 200 includes a circuit board 210 and a plurality of light sources 220. The circuit board 210 is mounted on the lamp housing 100, and the plurality of light sources 220 are disposed on the circuit board 210 and located on a side of the light-transmitting member 120 away from the light-blocking member 110, so as to ensure that light emitted from the light sources 220 firstly passes through the light-transmitting member 120 and then the light-emitting holes 111. The intersection point of the side lines corresponding to the light emitting angles of the plurality of light sources 220 is staggered with the light exit hole 111. In other words, at least part of the light emitted by the light sources 220 faces the light exit holes 111, and at this time, through the structural design and the adjustment of the installation position, the intersection point of the edge light of the plurality of light sources 220 is controlled to fall on the light blocking member 110, but not on the light exit holes 111, so that the direct light emitted by the light sources 220 is prevented from interfering in the light exit holes 111 after passing through the light transmitting member 120 to form bright spots or bright spots, and the occurrence of lamp shadows is avoided, thereby improving the rendering effect of the atmosphere lamp.

It can be understood that the light emitted from the light source 220 partially enters the light exit hole 111 after being reflected once or multiple times by the housing 10 of the display device, and the reflected light is uniform and soft, and no bright spot or bright spot is formed in the light exit hole 111 due to interference.

Optionally, the light source 220 is a light emitting diode. For example, the light source 220 is an organic light emitting diode or a quantum dot light emitting diode.

Optionally, the light emitted by the light source 220 is color tunable.

Optionally, the circuit board 210 is a printed circuit board.

In this embodiment, the circuit board 210 is mounted on the lamp housing 100, and may refer to that the circuit board 210 is mounted on the light blocking member 110 or the light transmitting member 120, or that the circuit board 210 is connected to the light blocking member 110 and the light transmitting member 120 respectively.

Specifically, the circuit board 210 is detachably mounted to the light barrier 110, so as to facilitate replacement and maintenance of the light source assembly 200, and also facilitate replacement of the lamp housing 100 and change of the appearance of the atmosphere lamp.

Alternatively, referring to fig. 8, the light blocking member 110 is provided with a first connecting portion 113, the circuit board 210 is provided with a second connecting portion 211, and the circuit board 210 is connected with the first connecting portion 113 through the second connecting portion 211 so as to be mounted on the light blocking member 110. The first connecting portion 113 is a connecting column, the second connecting portion 211 is a connecting hole, and the connecting column can be inserted into the connecting hole, so that the circuit board 210 is connected with the light blocking member 110.

Of course, the first connecting portion 113 and the second connecting portion 211 may also be connecting holes, and the circuit board 210 and the light blocking member 110 are connected by fasteners penetrating through the first connecting portion 113 and the second connecting portion 211.

In addition, the first connection portion 113 and the second connection portion 211 may also be other connection structures as long as the circuit board 210 and the light blocking member 110 can be connected, and are not limited only herein.

Optionally, the number of the second connecting portions 211 is multiple, the multiple second connecting portions 211 are distributed at intervals along the circumferential direction of the circuit board 210, the number of the first connecting portions 113 is the same as that of the second connecting portions 211, and the circuit board 210 and the light blocking member 110 are connected in a multipoint and uniform manner through the multiple first connecting portions 113 and the multiple second connecting portions 211, so that the connection is firmer and more reliable.

Optionally, referring to fig. 8, the circuit board 210 is provided with a first fastening hole 212, the light blocking member 110 is provided with a first fastening block 114, and the first fastening block 114 is detachably inserted into the first fastening hole 212.

In an embodiment, referring to fig. 8, the circuit board 210 has a plurality of second connecting portions 211 and two or more first fastening holes 212, and the plurality of second connecting portions 211 and the two or more first fastening holes 212 are spaced apart from each other along a circumferential direction of the circuit board 210. For example, the outer contour of the circuit board 210 includes two oppositely disposed straight sides and two oppositely disposed semicircular arc sides, two ends of the semicircular arc sides are respectively connected with ends of the two straight sides, similar to a standard elliptical runway, the circuit board 210 has four second connecting portions 211 and two first fastening holes 212, each second connecting portion 211 is disposed near one end of the semicircular arc side, and each first fastening hole 212 is disposed near a midpoint of the corresponding straight side.

In some embodiments, referring to fig. 5, 6 and 8, the central portion of the lamp housing 100 is a mounting region 102, and the circuit board 210 is mounted to the mounting region 102. A plurality of light sources 220 are along the marginal circumference interval distribution of circuit board 210, and a plurality of light-emitting holes 111 are close to the edge setting of circuit board 210 to the light that light source 220 sent directly faces light-emitting holes 111, does not fall on circuit board 210, avoids light to be sheltered from by other devices on the circuit board 210, and a plurality of light-emitting holes 111 are close to light source 220, and the illuminance is better, and it is better to look the effect.

In some embodiments, the middle of the light-transmitting member 120 has a first hollow area 124 with a shape matching the outer contour of the circuit board 210, and the circuit board 210 is located in the first hollow area 124 and connected to the light-blocking member 110. In addition, the periphery of the circuit board 210 is in close contact with the light-transmitting member 120, thereby preventing light leakage.

In some embodiments, referring to fig. 7, the light sources 220 are sequentially distributed at intervals along the first curve 221, the light sources 220 emit light toward the same side of the first curve 221, the intersection points of the edge lines corresponding to the light-emitting angles of every two adjacent light sources 220 on the first plane are sequentially connected to form a second curve 222, and the light-emitting holes 111 are located on one side of the second curve 222 away from the first curve 221. The first plane is a plane parallel to the plane on which the first curve 221 is located.

Optionally, the second curve 222 lies in the first plane.

The plurality of light sources 220 emit light toward the same side of the first curve 221, which means that the number of light sources 220 illuminating the side area of the first curve 221 is increased, and the brightness of the side area is relatively uniform. Meanwhile, in the region between the first curve 221 and the second curve 222, there is a dead angle for illumination in a partial region, there is no light coverage, and the light intensity is too strong because the partial region is too close to the light source 220, thereby causing uneven brightness distribution. And the side of the second curve 222 far from the first curve 221 is covered by at least one light ray of the light source 220, most of the area is covered by the light rays emitted by more than two light sources 220, the brightness is uniform, and the light outlet 111 is arranged on the side of the second curve 222 far from the first curve 221, so that the light rays passing through the light outlet 111 are uniform, and the occurrence of lamp shadows is reduced.

Optionally, the first curve 221 is a straight line, a circular arc line, a wavy line or a closed line.

In one possible example, the first curve 221 is a closed line. For example, the first curve 221 is a circle, an ellipse, or a polygon.

After the first curve 221 and the distribution position of the light sources 220 are determined, the position and shape of the second curve 222 are determined accordingly. For example, when the first curve 221 is a straight line, if the plurality of light sources 220 are uniformly spaced, the second curve 222 is also a straight line, and if the plurality of light sources 220 are non-uniformly spaced, the second curve 222 may be a wavy line.

Referring to fig. 7, in an embodiment, the first curve 221 is a racetrack shape (fig. 7 is a partial view, so the first curve 221 is only shown as one arc segment of the racetrack shape). The intersection points of the sidelines corresponding to the light emitting angles of the two adjacent light sources 220 on the first plane are C, D and E, respectively, and the intersection points C, D and E are sequentially connected to obtain a runway-shaped second curve 222 (fig. 7 is a partial view, so the second curve 222 only shows one arc segment of the runway shape).

Specifically, referring to fig. 7, the intersections of the sidelines corresponding to the light emitting angles of the two light sources 220 separated by two light sources 220 on the first plane are sequentially connected to form a third curve 223, that is, the intersections of the sidelines corresponding to the light emitting angles of the light sources 220 at two ends among the four light sources 220 continuously disposed are sequentially connected to form the third curve 223. For example, referring to fig. 7, the intersection points of the side lines corresponding to the light emitting angles of the two light sources 220 separated by two light sources 220 are F and G, and the intersection points F and G are sequentially connected to obtain a third curve 223. The light exit hole 111 is located between the second curve 222 and the third curve 223.

According to the first law of illumination, the illumination of the light exit 111 is larger as the distance between the light exit 111 and the light source 220 is shorter. Thus, the light exit hole 111 is located between the second curve 222 and the third curve 223, the brightness of the light exit hole 111 is moderate, the light is uniform, and the visual effect is good.

Specifically, the second curve 222 and the third curve 223 form the annular intermediate region 101 therebetween, and the brightness distribution in the circumferential direction of the intermediate region 101 is uniform. The number of the light emitting holes 111 is multiple, and the light emitting holes 111 are sequentially distributed at intervals along the circumferential direction of the middle area 101, so that the brightness of each light emitting hole 111 is consistent, and the visual effect is good.

Optionally, the light blocking member 110 is disposed in an inclined manner toward a side close to the light source 220 corresponding to the sidewall of the annular middle area 101, which is beneficial to gathering light in the middle area 101 and the light exit hole 111, so that the illumination intensity is improved, and the rendering effect is good.

The light-transmitting member 120 is integrally formed and covers the light-emitting holes 111. In other words, the light-transmitting member 120 extends along the circumferential direction of the annular middle region 101, and covers the plurality of light-emitting holes 111 and the intervals between the light-emitting holes 111, so that the light-emitting holes 111 are better sealed, light is prevented from directly passing through the light-emitting holes 111 without passing through the light-transmitting member 120, and light leakage is prevented.

Specifically, the surface of the light-transmitting member 120 extending in the circumferential direction of the intermediate region 101 is a flat surface. In other words, the surface of the light-transmitting member 120 covering the light-emitting hole 111 and the space between the light-emitting holes 111 is a flat surface without a folded edge, so as to prevent light from being reflected by the folded edge and interfering in the light-emitting hole 111, thereby preventing the occurrence of lamp shadows.

When the light outlets 111 are located in the middle area 101, a junction of side lines corresponding to light emitting angles of two light sources 220 separated by one light source 220 on the first plane may fall into the light outlet 111, which may cause a light shadow due to light interference. Therefore, in a possible example, the position of the light exit hole 111 is staggered from the intersection point of the side lines corresponding to the light emitting angles of the two light sources 220 separated by one light source 220, so as to avoid the occurrence of lamp shadows.

Specifically, referring to fig. 7, the light blocking member 110 is provided with a light blocking sheet 112, the light blocking sheet 112 extends from the side wall of the light exit hole 111 to the middle of the light exit hole 111, and an intersection point of side lines corresponding to the light emitting angles of two light sources 220 separated by one light source 220 on the first plane falls on the light blocking sheet 112, so as to prevent the intersection point from falling in the light exit hole 111 to cause a lamp shadow.

It is assumed that the intersections of the edges corresponding to the light emitting angles of the two light sources 220 separated by one light source 220 are sequentially connected to form a fourth curve 224. That is, of the three light sources 220 that are continuously provided, the intersections of the side lines corresponding to the light emission angles of the light sources 220 located at both ends are sequentially connected to form the fourth curve 224. For example, referring to fig. 7, the intersections of the side lines corresponding to the light emitting angles of two light sources 220 separated by one light source 220 are H, I, J and K, and the intersections H, I, J and K are sequentially connected to obtain the fourth curve 224. In some embodiments, since there is no intersection point of the side lines corresponding to the light emitting angles of the light sources 220 between the second curve 222 and the fourth curve 224, when the light outlet 111 is located between the second curve 222 and the fourth curve 224, the occurrence of lamp shadows can be avoided.

In still other embodiments, the light exit 111 is located between the third curve 223 and the fourth curve 224, so that lamp shadows can be avoided.

In one embodiment, referring to fig. 5 and 8, the ambience lamp further comprises a lamp shade 300. The lamp cover 300 is mounted on the light blocking member 110 and is located on a side of the light blocking member 110 away from the light transmissive member 120. The light outlet 111 is covered by the lamp cover 300, which can prevent the appearance of the atmosphere lamp from being contaminated by dust.

In addition, the lampshade 300 enables the light-transmitting appearance of the atmosphere lamp to be more stereoscopic, and the shape of the lampshade 300 can be flexibly arranged according to the shape, so that the appearance color and the shape of the atmosphere lamp are more matched with the surrounding environment. The lampshade 300 is also used for shielding strong light to prevent the light from directly irradiating human eyes to cause dizzy.

Specifically, referring to fig. 4, a light exit gap 301 is formed between the outer edge of the light blocking member 110 and the outer edge of the lamp cover 300, a protrusion 123 for filling the light exit gap 301 is disposed on the outer edge of the light transmitting member 120, and an intersection point of sidelines corresponding to the light emitting angles of the plurality of light sources 220 is staggered from the light exit gap 301. Atmosphere lamp is except that the light-emitting of light-emitting hole 111, still through light-emitting clearance 301 light-emitting, and light-emitting position and light-emitting shape are abundanter, are favorable to improving and look the effect.

In one embodiment, referring to fig. 4, a protection cavity 302 is formed between the lamp housing 300 and the lamp housing 100.

Optionally, the protection cavity 302 is a sealed cavity to prevent light from leaking from the edge of the lamp housing 100 without passing through the lamp cover 300.

In one embodiment, referring to fig. 8, the lamp housing 300 is detachably mounted to the light barrier 110, so as to facilitate replacement and maintenance of the lamp housing 300.

Specifically, the light blocking member 110 is provided with the third connection portion 115, and the lamp cover 300 is provided with the fourth connection portion 303. The lamp cover 300 is connected to the third connection portion 115 through the fourth connection portion 303 to be mounted to the light blocking member 110.
