Abstract

The invention relates o a novel LED display screen module. The adopted technical scheme is as follows: a transparent device is connected with a decoration housing through a sealing rubber ring to form a closed body, an LED control device, a power supply device and an LED light-emitting array plate are arranged in the closed body, and an LED reflection shield is assembled on each light-emitting pipe of the LED light-emitting array plate. Compared with the prior art, the novel LED display screen module has the advantages of reducing cost, decreasing light pollution and being capable of being largely applied to the wall decoration industry.

Description

New LED display screen module

Technical field

The invention relates to a kind of New LED display screen module in wall decoration industry large-area applications.

Background technology

In LED photoelectric display field; LED display is used and is approved by the people gradually; Conventional products can not large-area applications in industries such as wall decorations because of the cost reason, because consider the problem of lumination of light emitting diode angle and brightness, luminous point all is that focusing is luminous simultaneously; Brightness is very big, closely stimulates very big to human eye.Under therefore a lot of environment, the light pollution phenomenon is very serious.

Summary of the invention

The purpose of the invention has provided and has a kind ofly compared with prior art reduced cost, and reduces light pollution and power consumption, can be on the wall decoration industry New LED display screen module of large-area applications.

The technical scheme that the invention is adopted is: New LED display screen module: transparent unit connects and composes obturator through O-ring seal and decorative shell; Be provided with LED control device, supply unit and LED light-emitting array strake in the obturator, assembling LED reflection shield on each luminotron of LED light-emitting array strake.

Above-mentioned New LED display screen module: described transparent unit is tempered glass or plastic sheeting or transparent resin.

In numerous LED screen factories; The LED module of all size of producing all is to adopt on conventional shell, the circuit board paster welding chip for driving and another side directly welds luminotron, carries out encapsulating again and handle, and water proof and dust proof, the luminotron of selecting for use are the circle or the ellipse luminotron of band focusing function; Outdoor screen lighting angle is 90 °--110 °; Indoor is 120 °, and especially outdoor screen is very high in brightness at night, and light pollution can not be avoided.Every square metre of area of generalized case sub-screen is 3906 or 17222 of 10000 points (outdoor) or 27777 points (indoor) etc., and cost is higher relatively, and the installation of metope large tracts of land influences popularization because of expense is high; The invention is on the technical foundation of LED screen, with the luminous point minimizing of unit area, on each luminous point, adds a reflection shield; Enlarge the display area of each luminous point; So, cost reduces significantly, on metope, can large tracts of land install; Reduced the power consumption and the brightness of whole screen simultaneously, the problem of light pollution is improved at night.

The invention is in order to realize the widespread use of LED screen cheaply; Create the new approaches of on each luminous point, adding reflection shield; The LED reflection shield can be transformed into the light of LED luminotron the uniform light of a branch of no hot spot, compares conventional mode from the utilization factor of the light source of single luminous point and improves a lot, though luminous point quantity reduces much on whole screen; But enlarged the display area of each luminous point, can effectively embody video effect preferably equally.Not only reduced the cost of whole project, also reduced power consumption simultaneously, installed for the metope large tracts of land and created possibility.

The LED reflection shield is compared traditional lighting and is had different effects, and in the invention, its effect is to converge in the scattered light that each luminous point of LED luminous tube array sends on the end face of reflection shield; Show that end face enlarges free from glare, no hot spot; Visual effect is soft; Dazzling sensation can not appear, simultaneously quasi-complement because of the LED luminous point reduces the problem of the video effect variation that occurs, therefore the metope screen can be able to application.

Adopt the New LED display screen module of the invention, compare, have the advantage that obviously reduces on the cost, reduced the light pollution of present conventional display screen simultaneously and reduced the power consumption of whole screen with traditional metope display screen.Because the invention designs for the module mode, the internal element function is independent, is convenient to produce, and compares other materials simultaneously when mounted and has in light weightly, easy for installation, do not need the metope of installing is selected, and assembled arrangement, positive fixing.

Embodiment

Like Fig. 1-shown in Figure 2; New LED display screen module: tempered glass (6) connects and composes obturator through O-ring seal (4) and decorative shell (3); Be provided with LED control device (1), supply unit (2) and LED light-emitting array strake (7) in the obturator, assembling LED reflection shield (5) on each luminotron of LED light-emitting array strake (7).

The LED reflection shield can be selected ABS plastic for use according to needs of the present invention, and is injection molded, and the reflection shield inwall adopts aluminum plating process; The diffusion part that LED is luminous reflexes on the end face to greatest extent; Improve light utilization, mounting means is: on each luminotron of color LED light-emitting array strake, assemble, the base and the wiring board of reflection shield are combined closely; Two pillars on the reflection shield are passed the pilot hole that wiring board is reserved; With the mode of heating pillar is dissolved and wiring board is integrated at opposite side, accomplish assembling.

The LED control device comprises signal drive circuit, horizontal drive circuit and column drive circuit etc.Its principle of work is as shown in Figure 3.Selecting for use of the invention circuit theory part is the routine use.
