Description

Technical Field

[0001] The utility model relates to the technical field of luminous glass, in particular to a high-brightness single-point controlled luminous glass. Background Art

[0002] Currently, in the field of LED-illuminated transparent glass, conductive film glass is typically produced using a laser engraving process. However, this process has a bottleneck: the density of LED light source layout is inversely proportional to the current in the engraving current channel. Given a given area of ​​conductive film, the greater the density of LED light source layout, the smaller the current flowing through the engraving current channel, and the lower the brightness of the LED light source. Conversely, the smaller the density of LED light source layout, the larger the current flowing through the engraving current channel, and the lower the brightness of the LED light source. Furthermore, this engraving process requires matching the length or internal resistance of each LED light source's current channel to ensure that each LED light source has essentially the same operating brightness. Therefore, when engraving lines, the line lengths of the farthest and closest LED light sources are often matched in a "U" shape. This extended engraving line length significantly reduces the efficiency of laser engraving. Since the layout density of LED light sources is inversely proportional to the current in the film current channel, LED light sources often use signal series control to save conductive film area, increase the current in the LED light source current channel, and ensure that the brightness of the LED light source is basically consistent. In a string of LED light sources, if a signal is not connected, the following LED light sources will not work, seriously affecting the use effect.

[0003] In the field of LED luminous transparent glass, there is another LED luminous glass technology that prints circuits directly on the glass. The advantages of this printed circuit are high brightness and high density of LED light source layout. However, when the conductive silver paste printed circuits are too dense, it will greatly affect the transmittance. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-brightness single-point controlled luminous glass with high laser engraving efficiency, which greatly improves the luminous brightness of the luminous glass. At the same time, point-to-point control is adopted to avoid the problem of large-area LED light sources not being bright.

[0005] The technical solution of the utility model is:

[0006] A high-brightness single-point controlled luminous glass comprising a conductive film glass, a plurality of LED light sources arranged in a matrix, and a positive power supply printed circuit. The conductive film of the conductive film glass is etched with a plurality of longitudinally extending insulating lines, which are divided into a plurality of groups. Each group of insulating lines demarcates an area electrically connected to a corresponding column of LED light sources.

[0007] The portion of the conductive film glass not etched with insulating lines is divided into a power positive input circuit, and the power positive input circuit is covered with a power positive printed circuit;

[0008] Multiple LED light sources are arranged on the portion of the conductive film glass where no insulating lines are etched. RGB pads are divided on the portion of the conductive film glass where no insulating lines are etched and in the area where each LED light source is arranged. The RGB pins of each LED light source are respectively connected to the corresponding RGB pads divided on the conductive film glass. In each group of insulating lines, a control circuit is formed between two adjacent insulating lines on the conductive film glass. In the portion of the conductive film glass where no insulating lines are etched, the portion serving as the RGB pad of each LED light source is respectively connected one by one with the three portions serving as the control circuits.

[0009] Each group of insulating lines is arranged on both sides of a column of LED light sources, and the bottom end of each group of insulating lines extends to the bottom end of the conductive film glass. In a column of LED light sources, the RGB soldering pads of the upper multiple LED light sources are connected one-to-one with the top end of the control circuit on their left side, and the RGB soldering pads of the lower multiple LED light sources are connected one-to-one with the top end of the control circuit on their right side.

[0010] The part of the conductive film glass serving as the positive power input circuit includes a horizontal circuit and multiple vertical circuits. One horizontal circuit is adjacent to the top of the conductive film glass. Each vertical circuit is arranged on one side of a column of LED light sources. The tops of the multiple vertical circuits are all connected to one horizontal circuit, and the bottoms of the multiple vertical circuits extend to the bottom of the conductive film glass. The positive power printed circuit includes one horizontal printed circuit and multiple vertical printed circuits. One horizontal printed circuit is completely covered and printed on one horizontal circuit, and multiple vertical printed circuits are completely covered and printed on multiple vertical circuits.

[0011] The power positive electrode printed circuit is a screen-printed conductive silver paste circuit.

[0012] Advantages of this utility model:

[0013] (1) The insulating lines of the present invention extend longitudinally along the conductive film glass. In each group of insulating lines, a control circuit is formed between two adjacent insulating lines on the conductive film glass, which reduces the length of the conductive film glass etching circuit, saves labor time, and improves the efficiency of laser etching.

[0014] (2) The portion of the conductive film glass of the present invention that is not etched with insulating lines is divided into a power positive input circuit. In the power positive input circuit, the bottom ends of multiple longitudinal lines serve as the power positive input terminals. Positive current is input through multiple power positive input terminals, effectively preventing the power positive input terminals from having poor contact, which would cause the working current of the LED power supply to decrease, the brightness to be dim or to decrease.

[0015] (3) The utility model covers the positive power input circuit with a printed positive power printed circuit. The positive power input circuit and the positive power printed circuit are both connected to the positive power supply, that is, the positive power input circuit and the positive power printed circuit are in a parallel relationship. By printing the positive power printed circuit, the input current is increased, so that the LED power supply presents a high brightness and high-density layout, and the positive power printed circuit is only printed on the positive power input circuit, which will not affect the transmittance of the luminous glass.

[0016] (4) The RGB pads of each LED light source of the present invention are connected to a corresponding control circuit respectively, and a single-point control method is adopted. Even if one LED light source works poorly or does not light up, it will not affect the normal operation of other LED power sources. BRIEF DESCRIPTION OF THE DRAWINGS
