[0045] like Figures 1 to 4 , Figure 6 As shown, the downlight provided in the embodiment of the present application includes a lamp housing 10, a driver 20, an LED light source 30, a lens 40, a liquid crystal panel 50 and a reflective component 60. The lamp housing 10 is formed with an installation space 11 and a light outlet 12 connected to the installation space 11. The driver 20 and the LED light source 30 are both arranged in the installation space 11, and the LED light source 30 is electrically connected to the driver 20. The lens 40 is arranged in the installation space 11, and the lens 40 has a light incident side 41 and a light emitting side 42 opposite to each other. The light incident side 41 faces the LED light source 30 and is arranged opposite to the LED light source 30. The liquid crystal panel 50 is arranged at the light outlet 12, and the liquid crystal panel 50 is located on the side of the lens 40 away from the LED light source 30. The liquid crystal panel 50 is arranged opposite to the light emitting side 42, and the liquid crystal panel 50 is electrically connected to the driver 20. The reflective assembly 60 includes a mounting bracket 61 and a reflective cup 62. The mounting bracket 61 is connected to the lamp housing 10. The reflective cup 62 is mounted on the mounting bracket 61. The reflective cup 62 has a light input end 621 and a light output end 622 that are opposite and connected. The light input end 621 is arranged opposite to the liquid crystal panel 50. The inner wall surface of the reflective cup 62 is a reflective surface 623. Figure 8As shown, when the liquid crystal panel 50 is in the off state, the light irradiated to the reflective surface 623 is reflected to the light emitting end 622 for emitting light for illumination.

[0046] In the downlight, the driver 20 starts the LED light source 30 to emit light, and the light is focused and propagated by the lens 40 and irradiated to the liquid crystal panel 50. When the driver 20 turns on the liquid crystal panel 50, Figure 8 As shown, the liquid crystals 53 of the liquid crystal panel 50 are arranged regularly, and the liquid crystal panel 50 in the on state has no diffusion effect on the light beam, that is, the light beam angle does not change after the light beam is transmitted from the liquid crystal panel 50, and the light beam does not irradiate the reflective surface 623 of the reflective cup 62, but directly illuminates through the light input end 621 and the light output end 622 of the reflective cup 62, thereby realizing a focused lighting mode in the form of focusing, as shown in FIG. Figure 5 1 shows the simulated illumination and light distribution of the downlight when the liquid crystal panel is in the on state. When the driver 20 is disconnected from the liquid crystal panel 50, that is, the liquid crystal panel 50 is in the off state, such as Fig. 9 As shown, the liquid crystal 53 of the liquid crystal panel 50 is in a disordered state, so that the liquid crystal panel 50 is atomized as a whole. Therefore, the liquid crystal panel 50 in the disconnected state has a diffusion effect on the light beam. The light beam is transmitted through the liquid crystal panel 50 in the disconnected state and becomes a divergent light beam. A part of the divergent light beam is irradiated to the reflective surface 623 of the reflective cup 62. The reflective surface 623 reflects the light and emits light from the light emitting end 622 for illumination. In this way, the light emitting beam angle becomes larger, thereby realizing a general lighting mode in the form of divergent light, such as Figure 7 The figure shows the simulated illumination and light distribution of the downlight when the liquid crystal panel is in the off state. Therefore, when the downlight of the present application is used for lighting, the driver 20 switches the liquid crystal panel 50 on or off, and the downlight can be used in the accent lighting mode for accent lighting, or in the general lighting mode for general lighting.

[0047] It can be understood that the liquid crystal panel 50 includes a first conductive layer 51, a second conductive layer 52, and liquid crystal 53 filled between the first conductive layer 51 and the second conductive layer 52. Figure 8 and Fig. 9 Wherein, the first conductive layer 51 and the second conductive layer 52 are both electrically connected to the driver 20 .

[0048] In the downlight of the embodiment of the present application, the greater the difference between the transmittance of the liquid crystal panel 50 when it is in the on state and the transmittance when it is in the off state (i.e., the greater the difference in the transmittance of the liquid crystal panel 50), the greater the difference in the luminous flux of the light emitted by the entire lamp will be. Therefore, the difference between the transmittance of the liquid crystal panel 50 when it is in the on state and the transmittance of the liquid crystal panel 50 when it is in the off state is less than or equal to 20%. In this way, it can be ensured that the luminous flux of the light emitted by the downlight when the liquid crystal panel 50 is in the on state and the luminous flux of the light emitted by the liquid crystal panel 50 when it is in the off state differ by no more than 20%.

[0049] like Figures 2 to 4 , Figure 6 As shown, the lamp housing 10 includes a cylindrical housing 110 and a mounting cover 120. The cylindrical housing 110 forms an installation space 11, and the mounting cover 120 forms a light outlet 12. The inner wall of the installation space 11 is provided with a first connection structure 111. Fig.10 As shown, the mounting cover 120 includes a cover body 121 and a second connection structure 122 connected to the cover body 121, and the first connection structure 111 is connected to the second connection structure 122. Specifically, as Figures 2 to 4 , Figure 6 As shown, the first connection structure 111 is an annular groove, and the second connection structure 122 is a plurality of hooks uniformly distributed on the cover body 121 in the circumferential direction, and the plurality of hooks are hooked on the annular groove.

[0050] like Fig.10 As shown, the mounting cover 120 further includes a mounting structure 123 connected to the cover body 121, and the liquid crystal panel 50 and the lens 40 are both mounted on the mounting structure 123. Because the farther the distance between the liquid crystal panel 50 and the light-emitting side 42 is, the more uniform the brightness of the liquid crystal panel 50 is, so the surface of the light-emitting side 42 and the surface of the liquid crystal panel 50 are spaced apart. However, the farther the distance between the liquid crystal panel 50 and the light-emitting side 42 is, the lower the light-emitting efficiency of the light after being transmitted through the liquid crystal panel 50 will be, and the higher the overall height of the downlight will be. Based on this, in order to balance the light-emitting uniformity, light-emitting efficiency and the overall height of the downlight, both more uniform light-emitting and higher light-emitting efficiency can be obtained, and the overall height of the downlight can be prevented from being raised. Therefore, the distance between the surface of the light-emitting side 42 and the surface of the liquid crystal panel 50 is less than or equal to 25 mm.

[0051] In the downlight provided in the present application, the lamp housing 10 further includes a top cover 130, which covers one end of the barrel shell 110 away from the mounting cover 120. A mounting frame plate 113 is formed in the barrel shell 110, and the mounting frame plate 113 divides the mounting space 11 into an upper space and a lower space. When assembling the downlight, the driver 20 is installed into the upper space from one end of the barrel shell 110 assembled with the top cover 130, and the driver 20 is connected and fixed on the mounting frame plate 113, and then the top cover 130 covers the barrel shell 110 to complete the upper space. In addition, the LED light source 30, the lens 40, the liquid crystal panel 50 and the reflective component 60 are installed into the lower space from one end of the barrel shell 110 assembled with the mounting cover 120, and the LED light source 30 is connected and fixed on the mounting frame plate 113, and the lens 40, the liquid crystal panel 50 and the reflective component 60 are connected and fixed on the barrel shell 110.

[0052] Since the thickness of the liquid crystal panel 50 is only about 0.5 mm, the strength of the liquid crystal panel 50 is relatively low. In order to reduce the probability of the liquid crystal panel 50 being damaged during the assembly process, Figures 2 to 4 , Figure 6As shown, the downlight further includes a light-transmitting protective plate 54, which is mounted on the mounting structure 123, and is stacked with the liquid crystal panel 50, and is located on the side of the liquid crystal panel 50 away from the lens 40. In this way, the liquid crystal panel 50 is protected by the light-transmitting protective plate 54, thereby reducing the probability of the liquid crystal panel 50 being damaged during the assembly process. In addition, due to the protection of the liquid crystal panel 50 by the light-transmitting protective plate 54, the liquid crystal panel 50 is not easily damaged due to bumps and collisions during transportation even when the assembled downlight is in transportation.

[0053] like Figure 4 , Figure 6 and Fig.10 As shown, the mounting structure 123 includes a supporting periphery 124 and a plurality of barbs 125, and the plurality of barbs 125 are evenly distributed on the cover body 121 along the circumferential direction. In addition, the lens 40 is provided with an assembly periphery 43, and the light-transmitting protective plate 54, the liquid crystal panel 50 and the assembly periphery 43 are stacked in sequence. Then, the stacked light-transmitting protective plate 54, the liquid crystal panel 50 and the lens 40 are assembled together on the mounting cover 120, that is, the supporting periphery 124 and the plurality of barbs 125 clamp and fix the light-transmitting protective plate 54, the liquid crystal panel 50 and the assembly periphery 43. Next, the mounting cover 120, the light-transmitting protective plate 54, the liquid crystal panel 50 and the lens 40 are assembled together on the cylindrical shell 110, that is, the first connecting structure 111 is connected to the second connecting structure 122.

[0054] The light-transmitting guard plate 54 is generally made of optical materials with high transmittance, such as PC (Polycarbonate, also known as PC plastic; a high molecular polymer containing carbonate groups in the molecular chain), PET (Polyethylene terephthalate, commonly known as polyester resin), PMMA (Polymethylmethacrylate, a high molecular polymer, also known as acrylic or organic glass, with high transparency). In addition, the thickness of the light-transmitting guard plate 54 is greater than or equal to 0.8 mm to ensure that the light-transmitting guard plate 54 itself has sufficient strength.

[0055] In the downlight provided in the present application, the lens 40 is a condenser lens, wherein the lens 40 may be a TIR lens (total internal reflection, TIR, total internal reflection, also known as total reflection), or may be a condenser lens such as a Fresnel lens.

[0056] like Figure 2 , Figure 4 and Figure 6 As shown, the shell 110 is connected with a connecting ear 112, and the mounting bracket 61 includes a first bracket 611, and the first bracket 611 is provided with a slot 613, and the connecting ear 112 is snapped into the slot 613. In addition, the reflective cup 62 is installed in the first bracket 611. Figures 2 to 4 , Figure 6 As shown, the mounting bracket 61 also includes a second bracket 612, and the second bracket 612 is sleeved in the first bracket 611. Specifically, the first bracket 611 is provided with a plurality of hooks 624, and the inner wall of the second bracket 612 is provided with a circumferential annular protrusion, and the hooks 624 are hooked on the annular protrusion. When the connecting ear 112 is engaged with the slot 613 of the first bracket 611, the cylinder shell 110 and the second bracket 612 together restrict the first bracket 611, so that the first bracket 611 is stably sleeved in the second bracket 612. Figures 1 to 4 , Figure 6 As shown, the second bracket 612 is installed with a plurality of spring clips 70, and the plurality of spring clips 70 are evenly distributed along the circumference. Generally, the second bracket 612 is installed with two spring clips 70, and when the downlight is installed to the reserved lamp groove of the ceiling, the two spring clips 70 apply elastic force outward, thereby clamping the downlight as a whole in the reserved lamp groove.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
