Description

Light-transmitting metal panel with microporous matrix and light-emitting device with the light-transmitting metal panel

This creation relates to a light-transmitting metal panel, especially a light-permeable microporous matrix pattern penetrating through a thin metal plate, which has micro-holes that are not easily detectable by the naked eye, impervious to water, and when matched with a backlight module, each micro-hole The light energy emitted by the hole blends with the light emitted by the surrounding micro-holes to form a visual surface light.

The production of micro-holes in metal plates generally includes punching with molds, drilling with laser light, and etching with chemical liquids; the resulting micro-porous metal plates are mainly used to filter gaseous or liquid fluids, such as filter residues. , Oil filter, etc. Use the above-mentioned etching technology.

Such micro-holes can be so small that it is difficult to recognize the presence of the naked eye, for example, micro-holes smaller than 0.1 mm on a metal plate.

Moreover, if the water droplets do not exert external force on this kind of micropores, due to the cohesion of water molecules and the effect of surface tension, the water will not pass through this kind of micropores. The more difficult it is for moisture to penetrate.

In addition, the micro-holes of this size are arranged in a matrix in a pattern on the metal sheet, and the light of the backlight module penetrates these micro-holes. When the light passes through each micro-hole from the bottom, the light radiates on the surface. The degree of divergence and the degree of fusion of light and light will also determine whether the matrix of point-like light is visually regarded as the pattern shape of planar light.

In view of this, the main purpose of this creation is to propose a light-transmitting metal panel with a microporous matrix, including the use of a thin metal plate to penetrate a light-transmissive microporous matrix pattern, and the thickness of the metal thin plate and the aperture of the micropores The size definition of the relative relationship between the hole distance of the micropores and the micropores can meet the following requirements:

1. By defining the aperture of the micro-holes on the metal sheet, it is not easy to detect the existence of perforations on the metal surface.

2. By defining the diameter of the micropores on the metal sheet, static moisture is not easy to penetrate.

3. The matrix surface formed by defining the aperture of the micropores and the pitch of the micropores on the thin metal plate allows each light spot to be visually diffused and connected to form a surface light pattern when the backlight is penetrated.

By defining the range, it is possible to make the microholes on the metal sheet hard to be noticed by the naked eye, the water droplets are not easy to penetrate from the surface, and the light emitted from the bottom of the microporous matrix pattern can be diffused into planar light due to the special definition of the hole pitch.
