the adjusting piece mounting part 12 is arranged between the light beam splitting area and the shell opening 11, and the adjusting piece mounting part 12 is used for mounting a light adjusting piece 60 capable of adjusting the angle of the first light beam 91; the first light beam 91 is emitted out of the split spotlight 100 from the housing opening 11; the second light beam 92 passes through the diffuser 40 to form a scattered light 93, and then exits the light splitting spotlight 100.
Specifically, the housing 10 is used for providing a component mounting space and an optical path channel; the housing 10 is provided with a light source installation part, and the light source assembly 20 is installed in the light source installation part in a detachable connection manner.
It can be understood that the detachable connection mode may be a connection mode such as a threaded connection or a snap connection.
In the light splitting spotlight 100 provided by the present invention, the light splitting element 30 is disposed on the light path between the light source assembly 20 and the housing opening 11, so that the light emitted from the light source assembly 20 is split into at least two light beams with different emission angles, that is, the first-order light beam emitted from the light source assembly 20 passes through the region of the housing 10 where the light splitting element 30 is disposed, and then the first light beam 91 and the second light beam 92 with different irradiation directions are formed; in addition, the light-splitting spotlight 100 is configured such that the diffusion member 40 is disposed on the light path of the second light beam 92, so that the light emitted from the diffusion member 40 is more uniform and softer due to the scattering effect of the diffusion member 40, and is suitable for supplementary lighting of a human face.
Current bathroom illumination lamps and lanterns, single lamps and lanterns can only satisfy single illumination demand, in order to satisfy wash platform illumination demand, need set up shot-light or down lamp that shines towards the wash platform specially, in order to satisfy face illumination demand, need set up mirror side wall lamp specially, this kind of lighting scheme need set up multiple lamps and lanterns, and the installation is troublesome, consumes the cost.
As shown in fig. 1-3, the light-splitting spotlight 100 of the present invention can simultaneously satisfy the illumination requirements of a washbasin and a human face through a single lamp; the light splitting beam-splitting component 30 is arranged on the light path channel of the light splitting spotlight 100, so that the light emitted by the same light source component 20 is split into two directions to be irradiated, and the illumination requirements of two target areas can be met by a single lamp; the first light beam 91 of the light splitting spotlight 100 can be directly emitted from the shell opening 11 without passing through the diffusion piece 40, so that the light characteristics of the spotlight are retained, and the atmosphere illumination of a wash basin can be realized; the diffusion member 40 is disposed on the emission channel of the second light beam 92 of the light splitting spotlight 100 to scatter the second light beam 92 before emitting, that is, the light beam emitted from the light splitting spotlight 100 in another direction is uniform and soft, has no glare, and is suitable for supplementing light to human faces or spaces.
The spot light for illuminating the wash basin is usually installed on a ceiling or a wall side wall, the shell opening 11 of the spot light generally faces the wash basin, and due to the fact that the installation positions of the spot light are different, the vertical distance between the installation position of the spot light and the wash basin is different, the heights of users in the wash basin are different, and the like, when the light splitting spot light 100 is used, one light beam or the scattered light beam 93 irradiates one target area, the other light beam or the light beam cannot irradiate the other suitable target area, namely, the situation that the scattered light beam cannot appropriately irradiate a human face and a nearby area when the first light beam 91 irradiates the specified area of the wash basin, or the situation that the first light beam 91 cannot appropriately irradiate the specified area of the wash basin when the scattered light beam irradiates the human face and the nearby area may occur.
Therefore, in order to make the split spot light 100 of the present embodiment suitable for more installation and use scenes, the split spot light 100 of the present embodiment is provided with an adjusting member mounting portion 12 on the inner wall of the housing 10, and the adjusting member mounting portion 12 is used for mounting the light adjusting member 60 capable of further adjusting the direction of the first light beam 91; thus, when one of the light beams or the light rays cannot be properly irradiated to the target area, the user only needs to adjust the irradiation angle of the split light lamp 100 first so that the scattered light 93 emitted by the diffuser 40 can be irradiated to the face area, and then the light adjusting member 60 capable of adjusting the angle of the first light beam 91 is mounted to the adjusting member mounting portion 12, so that the first light beam 91 can be properly irradiated to the target area of the wash basin.
The adjusting part mounting part 12 of the present invention is configured to mount the light adjusting part 60 on the emitting light path of the first light beam 91, so as to facilitate users who do not have professional knowledge, and when the split spotlight 100 needs to be adjusted so that the scattered light 93 can be irradiated on the face area while the first light beam 91 is irradiated on the designated area of the wash basin, the appropriate light adjusting part 60 can be simply and easily mounted on the adjusting part mounting part 12 of the housing 10 under the remote guidance of a technician.
The invention further adjusts the emitting direction of the first light beam 91 by arranging the adjusting piece mounting part 12 to match with the light adjusting piece 60, and is more suitable for the operation of a common user compared with directly replacing the light beam splitting piece 30, because if the light beam splitting piece 30 is replaced, the position of the diffusing piece 40 can be further adjusted, which is more troublesome; the light adjustment member 60 is arranged on the light path of the second light beam 92 relative to the member adjustment member mounting portion 12, so that the adjustment can be more effectively performed to ensure that the scattered light 93 is irradiated to the second target region and the first light beam 91 is irradiated to the first target region.
