In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-6, the intelligent panel with uniform light display of the present invention comprises a front cover, a uniform light plate 20, a circuit board 30 and a rear cover 40 from the front to the rear. The front cover includes a cover 11 and a frame 12, the cover 11 is installed in the frame 12, the cover 11 and the light-equalizing plate 20 have corresponding key holes 13, and the keys 51 penetrate through the key holes. The keys 51 are mounted on a key holder 52, and the key holder 52 is mounted on the circuit board 30. The edge of the circuit board 30 is provided with a plurality of first LEDs 31, and a second LED32 is arranged below the key support 52.

For the sake of aesthetic appearance, the key hole 13 has several bar-shaped light-transmitting areas 14 around it, and the inside can be emitted through the bar-shaped light-transmitting areas 14. Preferably, the strip-shaped light-transmitting areas 14 are formed in a honeycomb shape, as shown in fig. 1-2.

In order to make the light emitted by the LED inside the panel uniform, a light equalizing plate 20 (the light equalizing plate can be made of acrylic material) is arranged behind the front cover, a corresponding key hole is arranged on the surface of the light equalizing plate 20, a plurality of first notches 23 are arranged on the side edge of the light equalizing plate 20, a plurality of first LEDs 31 are arranged on the edge of the circuit board 30, the first LEDs 31 correspond to the first notches 23 and are located in the first notches 23, and therefore the light of the first LEDs 31 is emitted into the light equalizing plate 20 to be refracted, and the light can be uniform.
