[0030] In order to better understand the purpose, structure and function of the utility model, the specific embodiment of the utility model "a waterproof backlight panel lamp" is further described in detail below in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 7 In this embodiment, the panel light includes a face ring 100 and a bottom shell 200, a light outlet 101 of the face ring 100 is provided with a light guide component 300, the face ring 100 and the bottom shell 200 are detachably connected, the light guide component 300 covers the light outlet 101 to form a closed space, a first waterproof spacer 201 is provided between the face ring 100 and the bottom shell 200; a second waterproof spacer 202 is provided between the light guide component 300 and the face ring 100, and by providing waterproof spacers at the connection gaps of the components, the sealing and waterproof performance of the panel light is greatly improved, and the service life is improved. The bottom shell 200 has a light-transmitting backlight bevel 203, and a main light bar 102 close to the light guide component 300 and a backlight bar 204 close to the backlight bevel 203 are arranged in the closed space; the light of the main light bar 102 passes through the light guide component 300 and is transmitted from the light outlet 101, and the light of the backlight bar 204 passes through the backlight bevel 203. The light can be transmitted from the light outlet 101 at the lower end of the panel light and the backlight bevel 203 at the upper end, which increases the backlight illumination range and further increases the light output brightness; at the same time, the main light bar 102 and the backlight bar 204 can emit light of different colors, forming a combination of different colors above and below, thereby increasing the application scenarios of the panel light.

[0032] It should be noted that in this embodiment, the panel light is in a round shape, and of course other shapes can be presented in other embodiments. The main light bar 102 and the backlight light bar 204 are both in a circular shape, so that the light output of the entire panel light is more uniform. The first waterproof spacer 201 and the second waterproof spacer 202 are preferably waterproof silica gel / waterproof foam, which are highly corrosion-resistant and waterproof materials.

[0033] See also Figure 3-Figure 5In the present embodiment, a closed ring 103 surrounding the light outlet 101 and protruding upward is provided on the face ring 100, an inner groove is formed between the closed ring 103 and the outer ring of the face ring 100, a second waterproof spacer 202 is sleeved on the closed ring 103 and located in the inner groove, and the light guide component 300 covers the inner groove and abuts against the closed ring 103 and the second waterproof spacer 202 at the same time; in this way, the second waterproof spacer 202 can be fixed, further increasing the waterproofness and sealing properties of the connection between the light guide component 300 and the face ring 100.

[0034] See also Figure 3 and Figure 6 In the present embodiment, the bottom shell 200 extends circumferentially to form a cover ring 205, the downward projection of the cover ring 205 completely covers the upper end surface of the outer ring of the face ring 100, and the cover ring 205 extends out of the outer side surface of the face ring 100 to ensure that the face ring 100 is completely covered; when the bottom shell 200 and the face ring 100 are combined, the cover ring 205 simultaneously covers and abuts against the first waterproof isolation component 201 and the upper end surface of the outer ring of the face ring 100, fixing the first waterproof isolation component 201 at the connection position between the bottom shell 200 and the face ring 100, thereby improving the waterproofness and sealing of the connection between the bottom shell 200 and the face ring 100.

[0035] See also Figure 2 and Figure 3 In this embodiment, the light guide assembly 300 includes a light guide 302 and a diffuser 303 arranged at upper and lower positions. In order to save space, the main light bar 102 is arranged in a vertical ring shape, and the light emission direction is horizontally inward. The light guide 302 is penetrated by the main light bar 102. The light of the main light bar 102 passes through the light guide 302 and then diverges vertically. The light guide 302 guides and changes the illumination direction. The diffuser 303 is close to the light outlet 101, and diverges the light guided by the light guide 302, so that the light is evenly emitted from the light outlet 101.

[0036] More specifically, in the present embodiment, the light guide assembly 300 further includes a reflector 301, which is located above the light guide 302. The reflector 301 reflects the light guided upward by the light guide 302 downwardly, so that the light is reflected toward the diffuser 303, thereby increasing the brightness of the light output from the light outlet 101. Meanwhile, the reflector 301 is located between the light guide 302 and the backlight strip 204, so as to reduce the interference between the different colors of light emitted from the light outlet 101 and the backlight bevel 203.

[0037] See also Figure 3 and Figure 6 The bottom of the backlight inclined surface 203 extends downward to form an isolation ring 206, which is located between the main light bar 102 and the backlight light bar 204, further isolating the main light bar 102 and the backlight light bar 204, reducing the interference between different colored lights emitted by the light outlet 101 and the backlight inclined surface 203.

[0038] See also Figure 1 and Figure 2 In this embodiment, the panel light also includes a hanging plate 400, which is connected to the bottom shell 200 for hanging and fixing. A third waterproof isolation member 401 is arranged between the hanging plate 400 and the bottom shell 200. The third waterproof isolation member 401 is preferably waterproof silica gel / waterproof foam to increase the waterproofness of the connection position between the hanging plate 400 and the bottom shell 200.

[0039] More specifically, in this embodiment, a wire outlet hole 402 is provided on the hanging plate 400, and a waterproof protective coil 403 is provided on the wire outlet hole 402. The waterproof protective coil 403 prevents water vapor / moisture from entering the panel light through the wire outlet hole 402, thereby improving the waterproof performance.

[0040] More specifically, in this embodiment, a timing module and a power-off protection module are also provided in the panel light. Both the timing module and the power-off protection module are electrically connected to the main light bar 102 and the backlight bar 204. A timing switch function can be set for the panel light, and automatic power-off protection can be provided in case of overload / short circuit.
