[0034] 3. The light source assembly 5 comprises: a light guide plate 8; a light emitting piece 12 is arranged on the side of the light guide plate 8.

[0035] Figure 4 is a perspective exploded view of the light source assembly 5 provided by the embodiment of the utility model; Figure 5 is a side view exploded view of the light source assembly 5 provided by the embodiment of the utility model; as Figure 4 and Figure 5 shown, the light emitting piece 12 is an RGBWW lamp bead. The lamp beads are arranged through spacing optimization to ensure the uniformity of the side light of the light guide plate 8 and optimize the light efficiency distribution;

[0036] RGBWW lamp beads are a kind of composite multi-channel light-emitting diodes (LEDs) that contain the following features and components:

[0037] (1) RGB channel: including red (Red), green (Green), and blue (Blue) three basic color channels; through different proportions of RGB combination, various colors can be realized for output, which is used to create atmosphere or enhance the color performance of panel lights.

[0038] (2) WW channel: containing warm white (Warm White) and cool white (Cool White) two white light channels; warm white (usually between 2700K and 3500K): suitable for creating a warm and comfortable environment; cool white (usually between 5000K and 6500K): suitable for work scenes, providing higher brightness and cold color temperature light.

[0039] In an optional embodiment, the RGBWW lamp beads are controlled by a driving control system. Specifically, RGBWW lamp beads are usually matched with PWM (Pulse Width Modulation) drivers to achieve precise color temperature and brightness adjustment by controlling the brightness of each channel. RGBWW lamp beads have five independent LED channels (red, green, blue, warm white, and cool white) inside. Each channel is controlled by an independent PWM signal. PWM is a technology that controls current output by changing the "duty cycle" of the pulse signal. The adjustment of the duty cycle determines the luminous intensity of the LED in the channel. When the duty cycle is high, the current output is more, and the brightness of the lamp bead increases; on the contrary, when the duty cycle is low, the current output is less, and the brightness of the lamp bead decreases. By adjusting the PWM signal ratio of the warm white channel and the cool white channel, white light output of different color temperatures can be achieved. For example, when the duty cycle of the warm white channel is higher than that of the cool white channel, the output light is biased towards warm color; on the contrary, the output light is biased towards cool color.

[0040] Further, the red, green, and blue channels achieve the output of almost all visible colors through the combination of PWM signals. For example: red + green = yellow light, green + blue = cyan light, red + blue = purple light.

[0041] RGBWW lamp beads can provide rich colors and meet different needs for color temperature and brightness in various scenes. Through reasonable lamp bead arrangement design, efficient and uniform light distribution of the light guide plate 8 can be achieved.

[0042] In an optional embodiment, the specific arrangement design of the RGBWW lamp beads can be: RGBWW lamp beads are evenly distributed along the side edges of the light guide plate 8; the distance between each group of RGBWW lamp beads is usually between 5-10 millimeters.

[0043] Further, the light source assembly 5 further comprises: a light reflecting film 9, a soft light film 10 and a diamond plate 11.

[0044] The light reflecting film 9 is arranged below the light guide plate 8; the soft light film 10 is arranged above the light guide plate 8; and the diamond plate 11 is arranged above the soft light film 10.

[0045] In a preferred embodiment, the light reflecting film 9 is arranged below the light guide plate 8, and a high reflectivity coating is coated on the surface of the light reflecting film 9, so as to reflect the downward scattered or lost light back to the light guide plate 8, thereby improving the utilization rate of light.

[0046] The soft light film 10 is arranged above the light guide plate 8; and the soft light film 10 is usually made of polycarbonate or PET material with high light transmittance, and the surface of the soft light film 10 is provided with micron-level diffusion particles or textures, so as to uniformly diffuse the light through the surface micro-particles, avoid the dazzling caused by direct illumination of light, make the light more uniform and softer, improve the visual comfort, and reduce the damage of glare to vision.

[0047] The diamond plate 11 is arranged above the soft light film 10, and the surface of the diamond plate 11 is engraved with micro-prism lines, so as to change the light propagation path through the micro-prism lines, effectively reduce the glare problem, and further smooth the light output, thereby improving the uniformity of illumination.

[0048] The panel lamp has the following beneficial effects:

[0049] The panel lamp comprises a shell, an end cover and a light source assembly 5, the shell comprises an upper shell 1 and a lower shell 2, the end cover comprises a left end cover 3 and a right end cover 4, the upper shell 1 and the lower shell 2 form a stable limiting structure through a plug-in structure, and are fixedly connected with the left end cover 3 and the right end cover 4 which are respectively sleeved at two ends of the upper shell 1 and the lower shell 2, so as to ensure the structural strength and durability of the light source assembly 5 as a whole; the plug-in structure design facilitates replacement of the light source assembly 5 or maintenance, thereby significantly reducing the maintenance cost; the light source assembly 5 adopts the light reflecting film 9, the soft light film 10 and the diamond plate 11, so as to make the light uniform and consistent, more soft, and also effectively reduce the problems of frequency flicker, glare and blue light, and the like, thereby improving the light efficiency of the panel lamp; and the light emitting piece 12 adopts an RGBWW lamp bead, so as to realize high color rendering, multi-color temperature and multi-color light effect output.
