[0035] According to some embodiments of the present application, referring to Figure 1 The present application provides a composite panel 1, comprising a metal plate 11 and a light-transmitting film 12. The metal plate 11 has a first surface 111 and a second surface 112 arranged opposite to each other along a first direction X, the first direction X being parallel to the thickness direction of the metal plate 11. The metal plate 11 is provided with a through hole 113 penetrating the first surface 111 and the second surface 112. The light-transmitting film 12 is provided on at least one of the first surface 111 and the second surface 112, and the light-transmitting film 12 at least covers the through hole 113.

[0036] The metal plate 11 may be made of aluminum, steel, iron, copper or other common metals.

[0037] The thickness of the metal plate 11 is the smallest of its three dimensions (length, width, thickness). Figure 1 As shown, the first direction X is the thickness direction of the metal plate 11 .

[0038] The first surface 111 and the second surface 112 of the metal plate 11 are two surfaces disposed opposite to each other along the thickness direction thereof. The first surface 111 and the second surface 112 may be substantially planes.

[0039] The metal plate 11 can be formed with a through hole 113 penetrating the first surface 111 and the second surface 112 by stamping or laser. The number of the through hole 113 can be one or more, which is not limited in the embodiment of the present application. Figure 1 Two through holes 113 are shown in FIG. The shape of the through holes can be square, circular or other shapes, which is not limited in the embodiment of the present application.

[0040] The light-transmitting film 12 is a transparent or translucent film with light-transmitting properties. The light-transmitting film 12 can be disposed on the first surface 111 or the second surface 112. Figure 1 As shown, the light-transmitting film 12 is arranged on the first surface 111.

[0065] Optionally, the tensile strength of the light-transmitting film 12 may be 10 MPa, 20 MPa, 30 MPa, 40 MPa, 50 MPa, 55 MPa, 60 MPa, 70 MPa, 80 MPa, 90 MPa, 100 MPa, or the like.

[0066] The tensile strength of the light-transmitting film 12 is 10 MPa to 100 MPa, which can provide the light-transmitting film 12 with good structural strength and reduce the probability of the light-transmitting film 12 being torn.

[0067] According to some embodiments of the present application, the melting temperature of the light-transmitting film 12 is 100° C. to 200° C.

[0070] The melting temperature of the light-transmitting film 12 is 100° C. to 200° C., which can make the light-transmitting film 12 have better high-temperature resistance and improve the reliability and stability of the light-transmitting film 12 .

[0071] According to some embodiments of the present application, the elongation at break of the light-transmitting film 12 is 5% to 30%.

[0072] The elongation at break refers to the elongation of the sample when it breaks, expressed as the percentage of the elongation increment to the original length. The elongation at break of the light-transmitting film 12 can be obtained according to the test method in GB / T 1040.3-2006.

Of course, more through holes 113 can be provided on the metal plate 11, for example, three, five, ten, twenty, fifty, one hundred, etc. Figure 3 As shown, fifteen through holes 113 are provided on the metal plate 11 .

[0077] In the case where a plurality of through holes 113 are provided on the metal plate 11, the light-transmitting film 12 may cover only a portion of the through holes 113 or may cover all of the through holes 113.

[0078] A plurality of through holes 113 are provided on the metal plate 11 , and the light-transmitting film 12 covers a part or all of the plurality of through holes 113 , so that more light can pass through the through holes 113 of the metal plate 11 and the light-transmitting film 12 , thereby obtaining better lighting or decorative effects.
