Abstract
The utility model discloses an outdoor light emitting diode (LED) double-color display screen module which comprises a shell body. The shell body is provided with a drive circuit board. A plurality of LED units are distributed on the drive circuit board in a matrix mode. Each LED unit is formed by two red LEDs and a green LED in a combining mode. The drive circuit board is covered with a waterproof glue layer which is provided with an insulating mask, and the insulating mask is fixed on the shell body and provided with a plurality of rows of through holes which correspond to the LED units. Each LED unit penetrates through the through hole and is exposed out of the insulating mask, and sun shields which are placed among each row of through holes are arranged on the insulating mask. Insulating property among the LED units is good, dustproof effect and waterproof effect are good, service life is long, bad effect of reflection rays to light emitting of the LED units is effectively lowered under shining of the sun, and displaying quality is improved.
Description
Technical field
The utility model relates to a kind of LED display, relates in particular to a kind of outdoor LED double-color display screen module.
Background technology
Along with the fast development of science and technology, the technology of LED display and industry have all obtained significant progress.Because it has that brightness is high, operating voltage is low, power consumption is few, maximization, life-span are long, shock-resistant, steady performance, and is widely used in the fields such as traffic, civil aviaton, finance, education, medical treatment, bank, security, communication, media advertising.LED display is that the LED pixel unit module that the LED luminotron consists of is arranged in matrix according to the assembly unit of actual needs size, with special-purpose display driver circuit, D.C. regulated power supply, software, framework and the outer a kind of display screen that consists of of decorating.
LED display is divided into indoor, open air and semi-outdoor by environment for use, divide by color monochrome is arranged, three kinds of dual base color and three primary colours (full-color, very color).Existing outdoor dual base color LED display module generally by housing, be located at the led drive circuit plate on the housing, the LED unit that welds or be mounted on the led drive circuit plate forms, insulating property between its LED unit are poor, and the LED unit is without the sunshade measure, under solar radiation, can produce the harmful effects such as reflection ray, affect display effect; In addition, because LED display exposes to the open air for a long time outdoor, be subject to the intrusion of rainwater and dust, cause the electronic devices and components in the housing to damage, affect its serviceable life.
Summary of the invention
Therefore, for the problem of above-mentioned existence, the utility model provides a kind of outdoor LED double-color display screen module, the good insulation preformance between its each LED unit, dustproof and waterproof is effective, effectively reduces the harmful effect that produces when reflection ray is luminous to the LED unit under the solar radiation.
For solving this technical matters, the utility model is taked following scheme: a kind of outdoor LED double-color display screen module, comprise housing, described housing is provided with drive circuit board, matrix distribution has a plurality of LED unit on the described drive circuit board, each LED unit is respectively by two red LED, a green LED is composited, be coated with a Waterproof glue line on the described drive circuit board, Waterproof glue line is provided with an insulation face shield, described insulation face shield is fixed on the housing, this insulation face shield is provided with the multirow through hole corresponding with described LED unit, and each LED unit passes the through hole lamp body and exposes the insulation face shield, the upper sunshading board that is provided with between the hole in respectively working of described insulation face shield.
Further, the height of described sunshading board is higher than described LED unit.
Further, be provided with water proof ring between described insulation face shield and the housing.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the utility model is owing to being provided with Waterproof glue line and insulation face shield at drive circuit board, in the insulating property that improved between each LED unit, played the effect of dustproof and waterproof, thereby the electronic devices and components of display screen module are not fragile, prolong its serviceable life; In addition, be provided with sunshading board at the insulation face shield, effectively reduce the harmful effect that produces when reflection ray is luminous to the LED unit under the solar radiation, improve display quality.Therefore, adopt the assembled outdoor dual-colored LED display screen of the utility model that outdoor environment complicated and changeable is had stronger adaptive faculty, display effect is good, dustproof and waterproof is effective, long service life.
Description of drawings
The structural representation of Fig. 1 the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment.
Embodiment
Now with specific embodiment the utility model is further specified by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, the utility model embodiment discloses a kind of outdoor LED double-color display screen module, comprise housing 1, described housing 1 is provided with drive circuit board 2, matrix distribution has a plurality of LED unit 3 on the described drive circuit board 2, and each LED unit 3 is composited by two red LED, a green LED.Be coated with a Waterproof glue line 4 on the described drive circuit board 2, this Waterproof glue line 4 effectively prevents rainwater intrusion drive circuit board 2, prevents that the electronic devices and components on the drive circuit board 2 from suffering damage.Waterproof glue line 4 is provided with an insulation face shield 5, and described insulation face shield 5 is fixed on the housing 1, and this insulation face shield 5 has also played dustproof effect in the insulating property that improve between each LED unit 3.For the sealing of further reinforced insulation face shield 5 with housing 1, all sides that are connected with housing 1 at insulation face shield 5 are provided with a water proof ring 6.This insulation face shield 5 is provided with the multirow through hole 7 corresponding with described LED unit 3, each LED unit 3 passes through hole 7 lamp bodies and exposes insulation face shield 5, be provided with sunshading board 8 between the hole 7 respectively working on the described insulation face shield 5, the height of described sunshading board 8 is higher than described LED unit 3, this sunshading board 8 effectively reduces the harmful effect that reflection ray under the solar radiation produces when luminous to LED unit 3, has improved the display quality of LED display.
Because the good insulating between each LED unit of the utility model, dustproof and waterproof is effective, and shadow shield can effectively reduce the harmful effect of reflection ray under the solar radiation when LED unit was luminous, improves display quality.Therefore, adopt the assembled outdoor dual-colored LED display screen of the utility model that outdoor environment complicated and changeable is had stronger adaptive faculty, display effect is good, dustproof and waterproof is effective, long service life.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, the technician in relevant field is not breaking away under the spirit and scope of the present utility model, and the various conversion of making and variation all belong to category of the present utility model, should be limited by each claim.
