The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] The utility model provides an emotional lighting fixture. Figure 1 FIG. 4 shows an exploded structural diagram of an emotional lighting fixture according to an embodiment of the present utility model. Figure 1 As shown, the mood lighting fixture includes a lamp body 1, on which a plurality of light sources 2 are arranged, an optical component 3 is arranged on one side of the light source 2, the optical component 3 includes a light guide plate 4 and an electrophotochromic film 5, the electrophotochromic film 5 is arranged on the side wall of the light guide plate 4, and a driving component 6 is also arranged on the lamp body 1, and the driving component 6 is electrically connected to the light source 2 and the optical component 3 respectively.

[0029] The technical solution of this embodiment is to simply add an optical component 3 with an electrophotochromic film 5 on the lamp body 1, and realize different color change rules through the control of the driving component 6, while giving people a pleasant and soothing atmosphere and mood lighting, enriching the functions of the ceiling lamp.

[0030] Further, such as Figure 1 and 2 As shown, the heat sink 7 is also provided inside the lamp body 1, and the plurality of light sources 2 include a main lighting 21 and an ambient lighting 22. The main lighting 21 is provided around the inner wall of the heat sink 7, and the ambient lighting 22 is provided around the outer wall of the heat sink 7. In this embodiment, the heat sink 7 is in the shape of a hollow shell, and a mounting hole 8 for accommodating the heat sink 7 is provided on the optical component 3. The heat sink 7 is installed in the mounting hole 8, and the ambient lighting 22 abuts against the inner wall of the mounting hole 8.

[0031] By installing the heat sink 7 in the mounting hole 8 of the optical assembly 3, the ambient lighting 22 is in contact with the inner wall of the mounting hole 8, and the ambient lighting 22 works in a side-emitting manner. The main lighting 21 provides the main lighting effect of the lamp, and the ambient lighting 22 presents different light colors and change rules, providing a pleasant and soothing ambient mood lighting. The main lighting 21 and the ambient lighting 22 are installed on the heat sink 7, which can ensure a good heat dissipation effect of the lamp.

[0032] In this embodiment, if Figure 3 As shown, the electrophotochromic film 5 is arranged on the side wall of the light guide plate 4 close to the rear shell 10. Specifically, the electrophotochromic film 5 is attached to the back of the light guide plate 4. The light source 2 emits light through the light guide plate 4, and the color of the electrophotochromic film 5 can be from transparent to milky white, or from transparent to blue, orange, brown, etc., or from blue, orange, brown, etc. to transparent. In a specific embodiment, a ready-made algorithm control module can be added to control the current of the driving component 6, so as to achieve different light color change effects.

[0033] Specifically, the electrochromic phenomenon (EC) refers to the continuous reversible change in the optical properties of a material under the action of an electric field or current. The electrochromic film 5, i.e., the electrochromic (EC) film, is a very commonly used material. The electrochromic film 5 can achieve different haze changes by loading different current duty cycles, and the electrochromic film 5 with different haze changes can present different transmittances and reflectivities. For example, the electrochromic film 5 with periodic changes in a sinusoidal curve can present periodic changes in reflective brightness. In a specific embodiment, the electrochromic film 5 can be formed by superimposing two or more films of different colors, and different color changes can be achieved through the combination of algorithms, such as gradual changes from orange to transparent, transparent to blue, green to transparent, and other effects.

[0034] Further, such as Figure 1 and 5 As shown, a sensor is also included, and the sensor is electrically connected to the driving component 6. In the present embodiment, the sensor is set as a spectral sensor 9, and the spectral sensor 9 is arranged on the lampshade 11. The spectral sensor 9 collects ambient light, so that the lamp can output different dynamic color changes according to different light environments. In other embodiments, a clock module can also be added, and the spectral sensor 9 collects ambient light, combines the physiological rhythm work and rest time, and feeds back to the microcontroller unit MCU in the driving component 6. The MCU controls the color change and transparency of the electrophotochromic film 5 in combination with the existing algorithm. Thereby, it is reflected in the color change of our lamps, and different dynamic color changes are output according to different light environments. At the same time, adjusting the color and intensity of the light according to the time period can better simulate natural light, help maintain the law of the biological clock, and be beneficial to the user's sleep and physical health.

[0035] Further, such as Figure 1 and 5 As shown, it also includes a rear shell 10 and a lampshade 11, and the heat sink 7 is detachably connected to the rear shell 10 and the lampshade 11 respectively. Among them, a plurality of positioning posts 12 are arranged on the lampshade 11, and corresponding positions of the heat sink 7 are provided with positioning holes 13 that cooperate with the positioning posts 12. It also includes a mounting plate 14, which is detachably connected to the rear shell 10, and the mounting plate 14 is also provided with a hook 15, which further facilitates the installation of the lamp. It should be noted that the driving component 6 on the lamp body 1 and the rear shell 10, the heat sink 7 and the rear shell 10 and the lampshade 11, and the rear shell 10 and the mounting plate 14 are also fixedly connected by screws or bolts.
