In one possible design, the first reflector has a first end to second end length that is greater than a first end to second end length of the second reflector.

In this design, the first end of the first reflector and the first end of the second reflector are connected to the supporting member, and the second end of the first reflector and the second end of the second reflector extend in a direction away from the supporting member. In the extending direction of the second end of the first reflector, the length of the first reflector is greater than that of the second reflector. The length of the first light reflecting piece is different from that of the second light reflecting piece, so that the orientation direction of the first opening is limited, and the irradiation direction of the light emitted by the light source and passing through the first opening is limited.

In any of the above embodiments, as shown in fig. 3, the first reflector 125 has a length from the first end to the second end that is greater than the length from the first end to the second end of the second reflector 126.

In this embodiment, the first end of the first reflector 125 and the first end of the second reflector 126 are connected to the carrier 124, and the second end of the first reflector 125 and the second end of the second reflector 126 extend away from the carrier 124. The first reflector 125 has a length greater than that of the second reflector 126 in the extending direction of the second end of the first reflector 125. By making the lengths of the first reflector 125 and the second reflector 126 different, the direction in which the first opening 123 is oriented is defined, thereby defining the irradiation direction in which the light emitted from the light source 140 passes through the first opening 123.

In some embodiments, the light emitting assembly 100 is used in a household lighting device such as a desk lamp, the first reflector 125 is located above the second reflector 126, and the length of the first reflector 125 is greater than that of the second reflector 126, so that the first opening 123 faces downward, that is, the light finally exits the light emitting assembly 100 through the first opening 123 after being reflected by the first reflective surface 121 located above.

In any of the above embodiments, the ratio of the length from the first end to the second end of the first reflector 125 to the length from the first end to the second end of the second reflector 126 is in the range of 2.5: 1 to 5: 1.

in this embodiment, the first end of the first reflector 125 and the first end of the second reflector 126 are connected to the carrier 124, and the second end of the first reflector 125 and the second end of the second reflector 126 extend away from the carrier 124. In the extending direction of the second end of the first reflector 125, the ratio of the length of the first reflector 125 to the length of the second reflector 126 ranges from 2.5: 1 to 5: 1. because the first opening 123 is disposed at the second end of the first reflector 125 and the second end of the second reflector 126, the size of the first opening 123 can be adjusted by reasonably configuring the ratio of the lengths of the first reflector 125 and the second reflector 126, so as to adjust the light-emitting range of the light-emitting assembly 100.

It is understood that the larger the ratio of the first light reflecting member 125 to the second light reflecting member 126, the larger the size of the first opening 123 is, and thus the larger the light emitting range of the light emitting assembly 100 is. The smaller the ratio of the first light reflecting member 125 to the second light reflecting member 126, the smaller the size of the first opening 123, and thus the smaller the light emitting range of the light emitting assembly 100.

As shown in fig. 4, in any of the above embodiments, the spacing between the first reflector 125 and the second reflector 126 decreases in a direction away from the carrier 124.

In this embodiment, the distance between the first reflector 125 and the second reflector 126 decreases from the direction close to the carrier 124 to the direction away from the carrier 124, so as to ensure that the light can be reflected on the first reflecting surface 121 and the second reflecting surface 122 for multiple times. Because the first end of the first reflector 125 and the first end of the second reflector 126 are connected to the supporting member 124, and the second end of the first reflector 125 and the second end of the second reflector 126 extend in a direction away from the supporting member 124, it can be ensured that the light is reflected by the first reflector 125 and the second reflector 126 and then output through the first opening 123.

It will be appreciated that the tendency for the spacing between the first reflector 125 and the second reflector 126 to decrease is designed according to actual needs.

Setting the magnitude of the reduction in the interval to be larger, the path that the light passes through in the light reflecting member 120 is shorter, and setting the magnitude of the reduction in the interval to be smaller, the path that the light passes through in the light reflecting member 120 is longer.
