Abstract
The utility model discloses a light emitting diode (LED) patch structure for outdoor display, which comprises a substrate and an LED lamp plate; the LED lamp plate is arranged on the substrate, and the LED lamp plate consists of a printed circuit board (PCB) and an LED light source which is arranged on the PCB; and the LED light source consists of a patch-type LED chip, a base plate for installing the LED chip and an epoxy resin transmission body for encapsulating the LED chip. Both the substrate and the PCB are provided with an annular groove for installing the LED light source, when vapor passes through the junction between the epoxy resin and the PCB, and the vapor can be concentrated inside the annular grooves without wetting and damaging the LED light source, so a strong waterproof function can be realized, and the LED patch structure is applicable to the outdoor display.
Description
Technical field
The utility model belongs to technical field of electronic components, relates to a kind of LED paster structure of outdoor demonstration usefulness.
Background technology
Along with the continuous maturation of light-emitting diode Manifold technology, the LED lamp is widely used in the decorative lighting technical field as light source.LED lamp as open air demonstration usefulness all will be taked fabulous waterproof measure.Traditional Waterproof LED illuminating module comprises the led circuit plate of glue shell and bar shaped; The upper surface of circuit board has paster LED; The led circuit plate is imbedded in the rectangular recess of glue shell, and the led circuit plate has the epoxy resin cure layer of high transmission rate to carry out water-tight with the top embedding in the glue shell strip groove.Embedding requires good technological level and high cost; When the technology of encapsulated epoxy resin is not consummate especially; Steam is easy to get into from colloid and glue shell junction, and led light source receives rainwater easily and soaks and damage when being applied to outdoor screen and outdoor lamp decoration.
The utility model content
The utility model technical problem to be solved provides a kind of LED paster structure of outdoor demonstration usefulness, effectively waterproof and be used for outdoor demonstration.
The technical solution of utility model is following:
A kind of LED paster structure of outdoor demonstration usefulness comprises substrate and LED lamp plate; Said LED lamp plate is arranged at above the substrate, and the LED lamp plate is made up of PCB circuit board and the led light source that is arranged on the PCB circuit board; Said led light source by SMD led chip, the epoxy resin light penetrating object that is used to the substrate of led chip is installed and is used for packaging LED chips forms.
Be equipped with the annular groove that is used to install led light source on said substrate and the PCB circuit board.
Beneficial effect:
The LED paster structure of the outdoor demonstration usefulness of the utility model; Be equipped with the annular groove that is used to install led light source on substrate and the PCB circuit board; When steam passes through epoxy resin and pcb board junction, can accumulate in the said annular groove, and can not soak the damage led light source; Thereby have extremely strong water-proof function, be applicable to outdoor demonstration.
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
