Description of the preferred embodiments

[0019] To make the purpose, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments in this invention, all other embodiments obtained by those skilled in the art without creative effort fall within the scope of this invention.

[0020] This embodiment provides a backlight structure. The backlight structure may be arranged on the edge of the electronic device. When the electronic device is in use, the backlight structure may emit colorful light to enhance the atmosphere. Among these, the electronic device may be a display screen of a desktop computer, a television, etc., or it may be a central control screen or an access control screen, etc. In this embodiment, it is exemplified by a wall-mounted central control screen of a smart home.

[0021] In one embodiment of the present invention, the above-mentioned backlight structure is arranged on the edge of the wall-mounted central control screen. If the wall-mounted central control screen is round, the backlight structure can be arranged on the round outer peripheral wall. If the wall-mounted central control screen is polygonal, the backlight structure can be arranged on the outer wall of one or more sides.

[0022] As in Fig. 1 to 5, the wall-mounted central control screen in the embodiment of the present invention includes a side frame 5 and a rear cover 6. The backlight structure is arranged inside the side frame 5 and the rear cover 6. The backlight structure includes light-emitting lamp beads 1, a lamp panel 2, and a specially shaped light guide strip 3. The specially shaped light guide strip 3 is provided with a straight groove 31 along its extending direction. The side of the specially shaped light guide strip 3 with the straight groove 31 is in contact with the lamp panel 2. The specially shaped light guide strip 3, the side frame 5, and the lamp panel 2 form a light space 4. A plurality of light-emitting lamp beads 1 are evenly arranged in the light space 4. The lamp beads 1 are mounted on the lamp panel 2.

[0023] How Fig. As shown in Figures 3 to 5, the specially shaped light guide strip 3 has a light entry surface 32 and a light exit surface 33. The side of the specially shaped light guide strip 3 facing the lamp panel 2 in the light space 4 forms the light entry surface 32. The light exit surface 33 is located on the edge surface of the wall-mounted central control screen. Preferably, the light exit surface 33 runs tangentially to the edge surface of the wall-mounted central control screen.

[0024] In the embodiment of the present invention, the plurality of light-emitting lamp beads 1 use LED lamp beads in RGB mode, which can achieve colorful lighting effects. By adjusting the spacing between the LED lamp beads, uniform light distribution can be achieved. Multiple light-emitting lamp beads 1 can also be replaced with a colorful light strip.

[0025] In the embodiment of the present invention, the specially shaped light guide strip 3 is a hard light guide strip, which has lower cost and better light emission characteristics.

[0026] Therefore, the uniformity of the light emission can also be achieved by the opacity and light transmittance of the material of the specially shaped light guide strip 3.

[0027] In the embodiment of the present invention, the light-emitting surface 33 is formed as a frosted surface. The light emitted by the light-emitting surface 33 can be diffusely reflected onto the wall, thereby creating a more atmospheric atmosphere.

[0028] The light from the light-emitting lamp beads 1 enters through the light entrance surface 32, is refracted and reflected in the specially shaped light guide strip 3, and finally exits from the light exit surface 33. Then, the light is diffusely reflected onto the wall, which can enhance the atmospheric effect.

[0029] As in Fig. As shown in Figure 5, in the embodiment of the present invention, a bottom plate 7 is connected to the side frame 5. The bottom plate 7 runs parallel to the rear cover 6. The rear cover 6, the specially shaped light guide strip 3, the lamp panel 2, and the bottom plate 7 are placed in order from top to bottom. The bottom plate 7 and the rear cover 6 are connected by screws 8. The screws 8 may also pass through the specially shaped light guide strip 3 and the lamp panel 2 at the same time.After tightening the screws 8, the specially shaped light guide strip 3 and the lamp panel 2 are pressed against each other, so that the specially shaped light guide strip 3 and the lamp panel 2 are fixed inside the wall-mounted central control screen to achieve a better fixing effect and avoid the sudden shock of the light guide strip 3 during use, which may affect the lighting effect.

[0030] As in Fig.As shown in FIGS. 3 to 5, the specially shaped light guide strip 3 in the embodiment of the present invention includes a plate-shaped fixing portion 34, a luminous extension portion 35, and a stepped connecting portion 36. Among them, the plate-shaped fixing portion 34 is sandwiched between the rear cover 6 and the lamp panel 2. The stepped connecting portion 36 is connected between the luminous extension portion 35 and the plate-shaped fixing portion 34. Pressing ribs 61 are provided on the inner surface of the rear cover 6. When the rear cover 6 is pressed against the stepped connecting portion 36, the pressing ribs 61 can be pressed against the plate-shaped fixing portion 34. A light exit gap is provided between the side frame 5 and the rear cover 6.After the plate-shaped mounting portion 34 is clamped by the rear cover 6 and the lamp panel 2, the luminous extension portion 35 extends through the light-emitting gap. The light-emitting surface 33 is tangential to the outer surfaces of the rear cover 6 and the side frame 5.

[0031] In summary, the wall-mounted central control screen of the present invention has a backlight structure on the sides. In the backlight structure, a plurality of light-emitting lamp beads are provided on the lamp panel. The light emitted by the light-emitting lamp beads 1 enters the interior of the specially shaped light guide strip 3 through the light entrance surface 32 of the specially shaped light guide strip 3 and is then refracted and diffused onto the light exit surface 33. Since the light-emitting lamp beads 1 use LED lamp beads with RGB mode, they can emit colorful colors. Furthermore, the light uniformity of the light exit surface 33 can be achieved according to the opacity and light transmittance of the material of the specially shaped light guide strip 3 and the pitch of the LED lamp beads.Furthermore, the surface of the light-emitting surface 33 is formed as a frosted surface. The emitted light is diffusely reflected onto the wall. Finally, the backlight effect of the wall-mounted central control screen can be achieved to enhance the atmospheric effect.
