Description

Technical Field

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

[0002] At present, in the field of LED luminous glass, most conductive film glasses use laser engraving technology, and some use engraving plus printing technology.

[0003] The existing conductive film glass still has the following problems: (1) If the LED density is large and the resolution is high, the working current is not only limited, but also the LED brightness is insufficient and uneven, brighter at a distance from the power supply end and darker at a distance from the power supply end. At the same time, a "U"-shaped circuit is used to match the internal resistance of the LED working circuit, and the laser engraving efficiency is low; (2) If the LED density is small, the resolution is low. Although the working current is large and the brightness is improved, it is difficult to meet the actual use due to the low resolution. At the same time, a "U"-shaped circuit is used to match the internal resistance of the LED working circuit, and the laser engraving efficiency is still low; (3) The power input terminal and the signal input terminal on the conductive film glass are on the same side, and the gold finger surface contact connection is used. After a period of use, poor contact will occur, seriously affecting normal use. In addition, it is time-consuming and laborious to install the gold finger. At the same time, it is easy to cause the gold finger and the socket to loosen and have poor contact during transportation, which is very laborious during maintenance. (4) Even if a conductive film circuit is combined with a printed circuit, only the positive or negative pole is often printed. There is still a difference in the internal resistance of each LED series working circuit, and there is still a difference in brightness if you observe carefully. (5) Transparent glass is used, and the circuit is printed on the transparent glass. This method greatly improves the LED density and brightness uniformity. However, since the printed circuit is an opaque visible circuit, it affects the light transmittance, the cost is high, and the process is complex, and the application field is limited.

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

[0006] A high-density and high-brightness LED luminous glass, comprising a conductive film glass, a plurality of LEDs arranged in a matrix, a positive and negative single-row pin socket and a signal single-row pin socket;

[0007] The conductive film glass is provided with a plurality of longitudinally extending scribed lines, which divide the entire conductive film on the conductive film glass into a plurality of positive conductive films, a plurality of negative conductive films, and a plurality of signal conductive films. The ends of each positive conductive film, each negative conductive film, and each signal conductive film are located at the longitudinal ends of the entire conductive film, and a corresponding positive conductive film and a corresponding negative conductive film are provided on the left and right sides of each signal conductive film, respectively. Each column of LEDs is electrically connected to a corresponding signal conductive film, as well as the positive conductive film and the negative conductive film on the left and right sides.

[0008] The positive and negative single-row pin sockets and the signal single-row pin sockets are respectively connected to the two longitudinal ends of the conductive film glass. Multiple positive conductive films and multiple negative conductive films are electrically connected to the positive and negative single-row pin sockets, and multiple signal conductive films are electrically connected to the signal single-row pin sockets.

[0009] The multiple engraving lines include multiple LED grouping engraving lines and multiple area division engraving lines. Both ends of the multiple LED grouping engraving lines and the multiple area division engraving lines pass through the two ends of the entire conductive film in the longitudinal direction. Each LED grouping engraving line divides the entire conductive film into multiple LED conductive films. Each column of LEDs is connected to a corresponding piece of LED conductive film. Two area division engraving lines are provided on each LED conductive film. The two area division engraving lines divide each LED conductive film into a positive conductive film, a negative conductive film and a signal conductive film. The positive power supply pin at the left end of each LED in each column of LEDs is electrically connected to the positive conductive film, the negative power supply pin at the right end is electrically connected to the negative conductive film, and the signal pin is electrically connected to the signal conductive film.

[0010] Each of the positive conductive films is divided into a plurality of positive electrode pads uniformly distributed along the longitudinal direction of the entire conductive film, and each of the negative conductive films is divided into a plurality of negative electrode pads uniformly distributed along the longitudinal direction of the entire conductive film. The positive power supply pin at the left end of each LED in each column of LEDs is electrically connected to the corresponding positive electrode pad, and the negative power supply pin at the right end of each LED in each column of LEDs is electrically connected to the corresponding negative electrode pad.

[0011] Each of the signal conductive films is divided into a plurality of signal blocks, the plurality of signal blocks are evenly distributed along the longitudinal direction of the entire conductive film, and each signal block is located between two adjacent LEDs in the longitudinal direction.

[0012] Each of the positive conductive films is printed with a positive power supply printed circuit, and each of the negative conductive films is printed with a negative power supply printed circuit. The distance between the positive power supply printed circuit and the positive power supply pin of a corresponding column of LEDs is equal to the distance between the negative power supply printed circuit and the negative power supply pin of a corresponding column of LEDs.

[0013] The conductive film glass is provided with a whole conductive film on the front side of which a transparent glass is bonded via an EVA film. The plurality of LEDs arranged in a matrix are packaged between the conductive film glass and the bottom surface of the EVA film. The top surface of the EVA film is bonded and fixed to the transparent glass.

[0014] The number of PIN pins of the positive and negative single-row pin socket and the signal single-row pin socket are not equal.

[0015] Advantages of this utility model:

[0016] (1) The utility model is provided with a film etching line extending longitudinally along the conductive film glass. The film etching line divides the entire conductive film into multiple positive conductive films, multiple negative conductive films and multiple signal conductive films, thereby reducing the length of the conductive film glass film etching line, saving work time and improving the efficiency of laser etching.

[0017] (2) The positive and negative single-row pin sockets and the signal single-row pin sockets of the present invention are respectively connected to the two ends of the conductive film glass in the longitudinal direction, so that the power supply and signal electrical channels are not led out from one end of the conductive film glass, but from both ends. At the same time, the single-row pin sockets are used to connect the electrical connection with the collection end, which avoids the interference and short circuit problems that may exist in the mixed input of power and signal, and is convenient for production and manufacturing and on-site installation, commissioning and maintenance. The number of PIN pins of the positive and negative single-row pin sockets and the signal single-row pin sockets is not equal, which can not only clearly distinguish the functions of the two single-row pin sockets, but also absolutely prevent the risk of short circuit caused by wrong insertion during construction, which is more reliable than the gold finger connection.

[0018] (3) The utility model divides each signal conductive film into multiple signal blocks, thereby reducing the attenuation during signal transmission.

[0019] (4) The utility model prints a positive power supply printed circuit on each positive conductive film, and prints a negative power supply printed circuit on each negative conductive film, thereby increasing the power supply current of the LED, saving the conductive film glass area, reducing the internal resistance, greatly improving the LED brightness and LED luminous uniformity, and allowing more LEDs to be arranged, greatly improving the density of the LED layout.
