Further, the diffuser 30 may be a diffuser plate, or may be a diffusing silicone lens.
The frame 10 includes a circular ring-shaped main body portion 11, and a first protruding portion 12 and a second protruding portion 13 protruding from an inner side edge of the main body portion 11 toward a center direction of the main body portion 11, the second protruding portion 13 is located below the first protruding portion 12, and a length of the second protruding portion 13 protruding toward the center direction of the main body portion 11 is greater than a length of the first protruding portion 12 protruding toward the center direction of the main body portion 11, so that the first protruding portion 12 and the second protruding portion 13 can form a step shape.

In order to ensure the aesthetic property of the decorative lamp 100, the main body 11 extends beyond the lower surface of the second protrusion 13 to form a receiving cavity 14 for receiving the second reflector 50 below the second protrusion 13. When the second reflector 50 is received in the receiving cavity 14, a lower surface of the second reflector 50 is flush with a lower surface of the main body 11.
The first reflector 40 is preferably a total reflection mirror, the second reflector 50 is preferably a half reflection mirror, and the first reflector 40 and the second reflector 50 are respectively located at two sides of the frame 10 in the thickness direction, so as to form a light mixing cavity (not numbered) between the first reflector 40 and the second reflector 50. The polarizing assembly 60 is located in the light mixing cavity and includes a polarizer 61 and a birefringent device 62, and the polarizer 61 and the birefringent device 62 are arranged up and down between the first reflecting member 40 and the second reflecting member 50.

As shown in fig. 6, a schematic diagram of the polarization component 60 is shown. From this figure it can be seen that: the light passes through the polaroid A to become linearly polarized light, the linearly polarized light is divided into o light and e light with mutually vertical polarization directions after passing through the birefringent device B, and the phase difference of the o light and the e light is as follows:
wherein n is e And n o The refractive index of the birefringent device B for o light and e light, λ is the wavelength of the incident light. If the wavelength of light meets the following formula:
when the polarization direction of the polarizer C is the same as that of the polarizer A, the emergent intensity is strongest, and when the incident light is white light, the emergent light shows the color due to the lack of light with other wavelengths; when the polarization direction of the polarizer C is opposite to that of the polarizer a, the emergent light intensity is 0, and when the incident light is white light, the emergent light shows complementary color due to lack of light with the wavelength. Thus, for the same type of birefringent material, its appearance color is related to the phase difference, i.e. to the thickness D of the birefringent device B.
As shown in fig. 7, for the light path diagram of the decorative lamp 100 of the present invention, it can be seen from the light path diagram: after the light emitted from the light strip 20 enters the light mixing cavity through the diffuser 30, a part of the light is emitted from the second reflector 50, and the other part of the light is reflected to the first reflector 40 through the polarization component 60, reflected by the first reflector 40 and emitted through the second reflector 50 through the polarization component 60, so as to realize color light emission.
Specifically, white light is emitted by the lamp beads 21, is homogenized by the diffuser 30 and is transmitted to the light mixing cavity between the total reflector 40 and the semi-transparent and semi-reflective mirror 50; then, a part of the light directly exits from the half mirror 50, and the other part of the light is reflected to the total reflection mirror 40 through the half mirror 50, and in this process, the light passes through the polarizer 61 and the birefringent device 62 and irradiates on the total reflection mirror 40, and at this time, the light has a polarization state (equivalent to passing through the polarizer a and the birefringent device B in fig. 6); then, the light beam is reflected by the total reflection mirror 40, passes through the birefringent device 62 and the polarizing plate 61 again (corresponding to the light beam passing through the birefringent device B and the polarizing plate C in fig. 6, the thickness of the light beam passing through the birefringent device B is corresponding to 2 × d), and is emitted from the half mirror 50, and at this time, the light beam is presented as a color light, and a part of the light beam is continuously reflected by the half mirror 50 back to the total reflection mirror 40, and the above process is repeated again.
In the above process, the polarization directions of the polarizer a and the polarizer C in fig. 6 are the same. Due to the polarization color-rendering principle, the thickness of the birefringent device 62 passed by each layer is increased, so that the color of each layer of light ring is different, and the color gradient effect can be realized.
