Abstract
The utility model discloses an outdoor LED display screen, which comprises a bottom housing and a face mask, wherein the face mask is formed by transparent colloid; a PCB with a plurality of LED lamp beads is mounted on a position next to the face mask and between the bottom housing and the face mask; a power supply for supplying power for the LED lamp beads is arranged on the back face of the PCB; packaging glues are filled between the PCB and the face mask; positions, corresponding to each LED lamp bead, of the packaging glue are reflective light cavities; and waterproof rubber rings are arranged at connecting parts of the face mask and the bottom housing. The outdoor LED display screen has simple and practical structure, is easy to mount, and has well waterproof effect by overally adopting the waterproof measure, allows the display effect of the display screen to be better by adopting the design of the reflective light cavities, improves the phenomenon that the conventional screen has spots, dim spots and bright spots, and has wide application range.
Description
Technical field
The utility model relates to a kind of LED display, particularly outdoor LED display screen, belongs to the LED lighting technical field.
Background technology
LED is the abbreviation of light emitting diode, is a kind of solid luminescence material that can convert electrical energy into luminous energy.Because its advantages of energy saving and environmental protection has the trend that replaces conventional light source gradually at present.LED display is an important application in this field, but existing LED outdoor display screen is from the diode package operation, the slotting weldering, embedding, the marine glue technology that comprise the later stage, the display screen that produces of structure influences the display screen quality because the wafer optical axis does not overlap with the diode mechanical axis and the diode later stage inserts to be welded and joins the luminotron optical axis and screen body plane 3 D stereo direction generation angle, height tolerance that causes in the process in the diode support cup thus.In addition, the heat radiation of LED display also is a problem of relatively paying close attention at present, and the high temperature that sunlight is exposed to the sun and self heat production forms is the major reason of the outdoor screen brightness decay of present LED.
The utility model content
The utility model namely is the problems referred to above that exist at present outdoor LED display screen, and a kind of outdoor LED display screen that has great heat radiation effect and improve existing screen spot, dim spot, bright spot phenomenon is provided.
Specifically, outdoor LED display screen described in the utility model, comprise drain pan and face shield, face shield is made of transparent colloid, nearly face shield place is provided with the PCB circuit board that plurality of LEDs lamp pearl is installed between drain pan and face shield, and the back side of PCB circuit board is provided with to the power supply of LED lamp pearl power supply, is filled with packaging plastic between PCB circuit board and the face shield, packaging plastic is reflector cavity corresponding to the position of every LED lamp pearl, and the position that face shield is connected with drain pan is provided with waterproof apron.
Further, the edge of described face shield protrudes and forms flange, and the place that drain pan matches with face shield then has groove, and flange inserts in the groove and locks through bolt.
Further, described reflector cavity inwall is arcwall face, planarea or parabolic profile.
Further, described reflector cavity inner wall surface is provided with reflecting coating.
Further, described reflecting coating is aluminium, silver or nickel coating.
Further, described PCB circuit board is aluminium base or copper base.
Outdoor LED display screen described in the utility model, simple and practical, install easily, and integral body is taked waterproof measure, have the excellent waterproof effect, and adopted the design of reflector cavity, make that the display effect of display screen is better, and existing screen spot, dim spot, bright spot phenomenon have been improved, applied range.
