Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Fig. 1 is a schematic structural view of a light-emitting device of an indoor unit of an air conditioner according to an embodiment of the present invention; fig. 2 is a schematic perspective view of the light guide member of the light emitting device of the indoor unit of an air conditioner. As shown in fig. 1-2, the light emitting device of the indoor unit of an air conditioner provided in this embodiment includes a lamp wick 200 and a light guide 100, where the light guide 100 includes an incident area 110, a light transmitting portion 120 and a light emitting portion 130, the incident area 110 is used for receiving light emitted by the lamp wick 200, the lamp wick 200 faces the incident area 110, the incident area 110 and the light emitting portion 130 are located on two opposite sides of the light transmitting portion 120, and the width of the light transmitting portion 120 increases from a side facing the incident area 110 to a side facing the light emitting portion 130.

The light emitting device of the indoor unit of an air conditioner in this embodiment is applied to a cabinet of an air conditioner, and the light emitting device of the indoor unit of an air conditioner is installed inside a panel, and a part of the incident area 110 located at the top is exposed out of a certain upper surface of the panel to transmit light outwards. Therefore, the concepts of "top" and "bottom" used in the present invention are expressed based on the placement posture of the cabinet in the normal use state. In fact, the light guide 100 does not exclude application to a wall-mounted indoor unit, and therefore, in this case, the concept of "top" and "bottom" does not necessarily mean that the distance from the floor is different.

By setting the width of the light transmitting portion 120 to be increased from the side facing the incident area 110 to the side facing the light emitting portion 130, the light emitted from the wick 200 can be received by the incident area 110 and propagated in the light transmitting portion 120, so that the light can be emitted toward the light emitting portion 130 in a radial shape, the light emitting portion 130 has brightness over the entire length thereof, the local concentrated point light source is changed to emit light as the strip light emitted by the light emitting portion 130, and the light emission of the light emitting device is more uniform, thereby improving user experience.

As shown in fig. 1 and 2, preferably, the light guide 100 is an arc-shaped plate.

Specifically, the light guide 100 is an arc plate, and when the panel on which the light guide 100 is installed is an arc, the light guide 100 may also be arc-shaped, and the curvature radius of the light guide 100 may be smaller than that of the panel on which the light guide 100 is installed. In another implementation, if the lighting device of an air conditioning indoor unit of the present embodiment is installed in an air conditioning indoor unit having a square prism shape, the light guide 100 may also be a flat plate.

Through setting up leaded light spare 100 into the arc, make it be convenient for install at indoor cabinet-type air conditioner's panel inboard, only expose out light portion 130 for the user can only see the light that light portion 130 sent, avoids making whole leaded light spare 100 all outwards send light, produces too big luminous region, dazzles at night.

In addition, the light transmitting portion 120 has a top side and a bottom side which are oppositely disposed, and a first side and a second side which are oppositely disposed and respectively connect the top side and the bottom side; the top side is adjacent to the light emitting portion 130, and the bottom side is adjacent to the incident area 110.

The shape of the light guide member 100 of the arc-shaped plate after being unfolded onto a plane on the arc-shaped cylindrical surface may be approximately trapezoidal, and correspondingly, the first side edge and the second side edge are two trapezoidal waists, which are both straight lines. Alternatively, in this embodiment, the first side edge and the second side edge of the light transmitting portion 120 may be a polygonal line, and the polygonal line may be formed by two or three or more straight lines. When the fold line is two pieces, the fold line opening may be toward the top edge. That is, the included angle between the two side edges of the middle lower portion of the light transmitting portion 120 is larger than the included angle between the two side edges of the upper portion of the light transmitting portion 120. The included angle between the first side and the second side of the light transmitting portion 120 may be 100 to 150 ° after the light transmitting portion 120 is unfolded to a plane. In addition, in the present embodiment, the base is not a straight line. In this embodiment, if the incident area 110 is unfolded, it may be rectangular or square, or rounded rectangular or rounded square, and the bottom side of the light transmitting part 120 is matched with the left, upper and right three sides of the incident area 110. Accordingly, the bottom side of the light-transmitting portion 120 may be a fold line with a downward opening, and whether rounded transitions are used between segments of the fold line may be determined according to the shape of the incident area 110.

In addition, in the present embodiment, the light transmitting portion 120 may be an axisymmetric pattern. In another implementation, the light transmitting part 120 may be an asymmetric pattern, and one end of the top surface of the light part 130 may be slightly brighter than the other end.

As shown in fig. 1, the thickness of the light-transmitting portion 120 is preferably reduced from the bottom edge to the top edge.

Specifically, in the present embodiment, the thickness of the light transmitting portion 120 may gradually decrease from the bottom edge to the top edge over the entire height thereof. In another implementation, the light transmitting portion 120 may be provided to be gradually thinner toward the light emitting portion 130 only in a middle portion thereof, for example.

By setting at least a part of the thickness of the light transmission part 120 to be gradually reduced toward the top edge, the light in the light transmission part 120 can be reflected more forward when being projected to the rear side of the light transmission part 120, that is, when being deviated from one side of the panel, thereby increasing the light intensity of the light emergent part 130 at the top.

FIG. 3 is a top view of the light guide shown in FIG. 2. As shown in fig. 3, the thickness of the light transmitting portion 120 preferably decreases from the line connecting the midpoints of the top and bottom edges to the first and second side edges.

Specifically, in the present embodiment, the thickness of the middle portion of the light transmitting portion 120 is 2 to 4 times that of the two side edge portions. Accordingly, the thickness of the light emitting portion 130 may be the same as the thickness of the top surface of the light transmitting portion 120. Even if the thickness distribution of the light emitting portion 130 is different from the thickness distribution of the light transmitting portion 120 in the horizontal direction, for example, the thickness of each part of the light emitting portion 130 is the same, the light flux transmitted to the light emitting portion 130 by the top surface of the light transmitting portion 120 is not uniform, so that the light emitting portion 130 can display different light fluxes in the length direction thereof, thereby obtaining the effect of gradual light and shade change.

The thickness of the light transmission part 120 is set to be thicker in the middle and thinner at both ends, so that the light flux passing through the top edge of the light transmission part 120 can be increased in the middle and decreased at both ends when the light intensity in the light transmission part 120 is relatively uniform. Further, the light flux emitted from the light emitting portion 130 is more in the middle and less at both ends, thereby realizing a gradual change in brightness.

As shown in fig. 2, preferably, the light transmitting part 120 is further provided with a first chamfered part 121, and the first chamfered part 121 is formed at a boundary between a side surface of at least one of the first side edge and the second side edge and an outer side surface of the arc-shaped plate.

Specifically, in this embodiment, the lower half portion at the intersection of the side surface of the first side and the second side and the outer side surface of the arc plate is provided with the first chamfering part 121, specifically, in the case that the first side and the second side are folding lines, the folding lines below the folding angles are provided with the first chamfering part 121. The first chamfered portion 121 may extend upward above the corner portion.

In addition, an included angle between the first chamfer portion 121 and the outer side surface of the light guide 100 may be 30 to 60 °, and further may be 45 °, that is, an included angle between the first chamfer portion 121 and the outer side surface of the light guide 100, and included angles between the first chamfer portion 121 and the surfaces where the first side edge and the second side edge are both 45 °.

By providing the first chamfered portion 121 at the above-described position, the light beam emitted toward the side surface where at least one of the first side edge and the second side edge is located can be reflected toward the inside of the light transmitting portion 120 by the outer side surface of the chamfered portion, and can be transmitted to the light emitting portion 130 through the side surface where the top edge is located as much as possible. Thereby improving the utilization rate of the light emitted by the lamp wick 200, further reducing the power of the lamp wick 200 under the condition of meeting the total light emission quantity output externally, and being beneficial to reducing the energy consumption.

As shown in fig. 1 to 3, it is preferable that the surface of the light transmitting part 120 is provided with a concave pit 122.

Specifically, the form of the concave pit 122 can refer to the concave pit 122 on the surface of the golf ball, wherein, preferably, the concave pit 122 can be arranged on the inner side surface and the outer side surface of the light transmitting part 120, the outer side surface is the side of the light transmitting part 120 facing the panel, and the inner side surface is the side of the light transmitting part 120 facing away from the panel.

Fig. 4 is a schematic perspective view of the light guide member shown in fig. 2, viewed from the inner side. As shown in fig. 4, in addition, when the wick 200 is located on the inner side of the incident region 110, the pits 122 may also be distributed on the outer side of the incident region 110, so as to prevent the light emitted from the wick 200 from directly passing through the incident region 110 in the thickness direction as much as possible, and improve the utilization rate of the light emitted from the wick 200. The respective entrance area 110 is directed towards a side of the wick 200, i.e. the inner side of the entrance area 110, and in this implementation the recess 122 is not provided to reduce the attenuation of the light intensity.

By providing the concave portion 122 on the surface of the light transmitting portion 120, the light emitted to the surface of the light transmitting portion 120 is reflected to the inside of the light transmitting portion 120 by the outer side surface of the concave portion 122, and is transmitted to the light emitting portion 130 through the side surface where the top edge is located as much as possible. Thereby improving the utilization ratio of the light emitted by the lamp wick 200, and further reducing the power of the lamp wick 200 under the condition of satisfying the total light emission quantity output externally, and being beneficial to reducing the energy consumption.

As shown in fig. 1, 2 and 3, a surface of the light emergent portion 130 facing away from the light transmitting portion 120 is preferably a frosted surface. That is, when the indoor unit lighting device is applied to a cabinet, the top surface of the light emitting portion 130 is a frosted surface.

By providing the surface of the light emergent portion 130 away from the light transmitting portion 120 as a frosted surface, the light emitted from the light emergent portion 130 can be made softer, and the eyes of the user can be prevented from being irritated at night.

As shown in fig. 1 and 2, the incident area 110 is preferably provided with a second chamfered portion 111, and the second chamfered portion 111 is formed at a boundary between a side surface of the incident area 110 far from the wick 200 and a side surface of the incident area 110 far from the light-transmitting portion 120.

Specifically, the included angle between the second chamfered portion 111 and the outer side surface of the light guide 100 may be 30 to 60 °, and further may be 45 °, that is, the included angle between the second chamfered portion 111 and the outer side surface of the light guide 100, and the included angle between the second chamfered portion 111 and the bottom surface of the light guide 100 are both 45 °.

The second chamfered part 111 is arranged, so that when the lamp wick 200 is positioned behind the incident area 110, the light emitted from the lamp wick 200 is reflected upwards, the light can mainly pass through the light transmission part 120 and is transmitted to the light emitting part 130, the proportion that the light emitted from the lamp wick 200 into the incident area 110 is directly emitted from the incident area 110 is reduced, the utilization rate of the light emitting line of the lamp wick 200 is improved, the power of the lamp wick 200 is reduced under the condition of meeting the same light emitting amount, and the energy consumption is reduced.

The operation principle of the embodiment is as follows:

the light ray exits from the wick 200, enters the incident region 110, encounters the second chamfered portion 111 of the incident region 110, and is reflected upward. Although the light reflected upward is not absolutely parallel light, a part of the light directly reaches the light exit portion 130 upward. Since the concave pits 122 are formed on the inner side and the outer side, the light encounters the concave pits 122, is reflected toward the solid interior of the light transmitting portion 120, passes through the solid portion of the light transmitting portion 120, and continues to be reflected by the inner side or the outer side, or is transmitted to the light emitting portion 130. Of course, if the light in the light transmitting portion 120 directly encounters the inner side and the outer side of the light transmitting portion 120, instead of the concave pit 122, a part of the light is reflected toward the inside of the light transmitting portion 120.

In addition, due to the first chamfered portion 121, light emitted outward in a fan shape from among the light rays in the light transmitting portion 120 can be reflected inward, so that more light rays can be emitted from the light emitting portion 130, rather than from the side surfaces of the first side edge and the second side edge of the light transmitting portion 120.

After the light is emitted to the light emitting portion 130, since the top surface of the light emitting portion 130, i.e. the light emitting surface of the light emitting portion 130, is a frosted surface, the uniformity of the light is improved, and the light can be emitted from the light emitting portion 130 more softly, so as to avoid dazzling at night.
