Problems solved by technology

The LED display screen is composed of several LED module arrays. The smallest assembly unit of the LED display screen is the LED module, and the LED module is made of a light-emitting dot matrix composed of several LED light-emitting chips. Once the LED chip on the LED module is broken, there will be a "dead point" on the display screen, resulting in incomplete or unclear display on the display screen. In this case, the unit board assembled with the LED module must be removed from the display screen. Down, the LED module cannot be repaired, and the LED module containing the dead point (one or more LED chips cannot work) must be replaced as a whole, resulting in waste of resources; if the LED display is installed on the wall, the entire display must be replaced. The screen box is removed from the wall, and then the above-mentioned LED module is replaced; therefore, the structure of the existing LED module brings problems of high maintenance cost, inconvenient maintenance, and low maintenance efficiency to the later maintenance of the LED display.

Abstract

The invention discloses an easy-maintaining LED module. A circuit module is provided with a light spot matrix consisting of a plurality of reflection cups, and an LED welding line pad and a pad of an LED lamp covered and protected by the reflection cup are arranged in the reflection cup; an LED chip in the reflection cup is electrically connected with the welding line pad which is electrically connected with the pad, and a layer of encapsulation glue is filled in the reflection cup; and the pad at the bottom of the reflection cup is electrically connected with the circuit module. The LED luminous chip is directly encapsulated in the reflection cup by glue to form the LED lamp, and the pad of the LED lamp at the bottom of the reflection cup can be welded with the pad reserved on the circuit module; and when an LED display screen has a luminous 'dead spot', the 'dead spot' on the LED module is replaced by using an LED lamp standard component, and the integral LED module does not need to be replaced, so the maintenance program is simplified, the maintenance efficiency and the maintenance safety of the LED display screen are improved and the maintenance cost is lowered.

Description

technical field [0001] The invention relates to an LED light-emitting diode light-emitting module, in particular to an easy-to-maintain LED module that can repair "light-emitting pixels" of an LED display screen conveniently and quickly. Background technique [0002] At present, large-screen LED displays have been widely used in various digital display fields. The LED display screen is composed of several LED module arrays. The smallest assembly unit of the LED display screen is the LED module, and the LED module is made of a light-emitting dot matrix composed of several LED light-emitting chips. Once the LED chip on the LED module is broken, there will be a "dead point" on the display screen, resulting in incomplete or unclear display on the display screen. In this case, the unit board assembled with the LED module must be removed from the display screen. Down, the LED module cannot be repaired, and the LED module containing the dead point (one or more LED chips cannot wor...
