Embodiment Construction

[0025] Please refer to figure 1 , figure 2 and image 3 , the white LED rainbow display screen of the present invention comprises a plurality of white LED lamp bodies 1, a plurality of light-shielding black plastic tubes 2, a plurality of relief sculpture material rectangular gratings 3, a cylindrical plano-convex lens array panel 4 and an LED power supply circuit, and an LED power supply circuit It includes a circuit board 5 , circuit wiring arranged on the circuit board 5 and a dedicated white light LED driver integrated circuit.

[0026] The white LED lamp body 1 includes a transparent conical (bullet-shaped) mold head 11, a white LED tube core and pins, and the pins of each white LED lamp body 1 are respectively welded on the circuit board 5 through small holes. The central axis (direction of the output beam) forms an angle of 45° with the plane of the circuit board 5 . A side of the circuit board 5 corresponding to the white LED lamp body 1 is covered with a filling ...

Abstract

The invention discloses a white LED rainbow display screen, which comprises a white LED lamp body, a shading black plastic tube, an embossed plastic rectangular raster, a cylindrical plane convex lens array panel and a white LED power supply circuit. One end of the shading black plastic tube is embedded at a conical tip of the white LED lamp body, the other end of the shading black plastic tube is attached to the embossed plastic rectangular raster, and an embossed raster surface of the embossed plastic rectangular raster is towards the shading black plastic tube; and the cylindrical plane convex lens array panel is attached to the upper surface of the embossed plastic rectangular raster. The white LED rainbow display screen has the effect as natural and beautiful rainbow in the air, and belongs to an LED display screen personally having the rainbow effect; the color of the rainbow changes along with the movement of an observer; a rainbow display control circuit is not needed, while a drive circuit of the white LED rainbow display screen is the same simpleness as a drive circuit of a single base-color display screen; and the white LED rainbow display screen not only has low cost, but also has a simple and reliable structure.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a novel LED display screen and a novel LED advertisement board. Background technique [0002] With the advancement of electronic display technology and the diversification of product specifications, in addition to monochrome display and full-color display, large-screen electronic displays and billboards also adopt a rainbow display method to enhance the contrast between display screens and billboards. Attractiveness to the human eye. As an example, LED rainbow displays (including LED rainbow text displays) are widely used in shops, companies, business signs and billboards. The existing LED rainbow displays (LED dot matrix rainbow displays) are composed of three-color LED image The plain lamp is assembled according to the dot matrix. Driven by the controller, it produces a rainbow-like gradient effect, which is dazzling and shining, adding some romance and poetic cha...
