Description

Technical Field

[0001] This invention relates to the field of LED display technology, and more particularly to an LED wide-viewing-angle dual-efficiency point light source pixel lamp. Background Technology

[0002] In the existing technology, many LED displays are composed of linear light strips and full-color display driver modules. Multiple full-color light sources are evenly arranged on the linear light strips, and the full-color display driver module is used to control the dynamic display of the full-color light sources. A light distribution lens is usually provided outside the full-color light source. The light distribution lens can make the light of the full-color light source spread evenly, forming a display effect with uniform distribution and soft color. However, such LED displays have insufficient brightness, insufficient color vibrancy, and low color contrast. Summary of the Invention

[0003] The purpose of this invention is to provide an LED wide-viewing-range dual-efficiency point light source pixel lamp, which can improve the brightness, color vividness and color contrast of LED displays.

[0004] This invention is implemented as follows: A wide-viewing-range dual-effect LED point light source pixel lamp includes a strip-shaped lamp panel, several monochromatic light sources, several full-color light sources, and a linear light-distributing lens. The light-distributing lens is installed parallel to the lamp panel and is located at the front end of the lamp panel. The full-color light sources are located on the center line of the lamp panel, forming a linear full-color light source group. The light-distributing lens spreads the light from the full-color light sources. The monochromatic light sources are symmetrically distributed on both sides of the center line of the lamp panel, forming a matrix-like monochromatic light source group. The light-distributing lens concentrates the light emission direction of the monochromatic light sources or allows the light emission direction of the monochromatic light sources to be projected normally along their original emission direction. The full-color light source group and the monochromatic light source group are arranged alternately and in a linear array on the lamp panel.

[0005] Furthermore, the light-distributing lens has a structure that is concave in the middle and convex on both sides.

[0006] Furthermore, both the monochrome light source and the full-color light source are grouped into sets of four to six.

[0007] Furthermore, the initial light emission angle of the full-color light source is 60-120 degrees, and the light distribution lens refracts and expands the light emission angle of the full-color light source to 180-210 degrees.

[0008] The beneficial effects of this invention are as follows: The monochromatic light source matrix group and the full-color light source linear group of this LED wide-viewing-range dual-effect point light source pixel lamp are alternately arranged and distributed in a linear array. The full-color light source is located on the center line of the lamp board, and the monochromatic light source is located on both sides of the center line of the lamp board. The full-color light source and the monochromatic light source are separated by a light distribution lens, so that the light emitted by the full-color light source is spread out, while the light distribution lens does not change the light emission direction of the monochromatic light source, or makes the light emission of the monochromatic light source relatively concentrated. This makes the pixel lamp form a uniform distribution of full-color light and soft light color in human visual effect, while the monochromatic light is dazzling and bright, with vivid colors and high color contrast, which can form a rich variety of light and color change effects.

[0011] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0012] As an embodiment of the LED wide-viewing-field dual-efficiency point light source pixel lamp described in this invention, such as Figures 1 to 5As shown, the system includes a linear lamp panel 11, a monochromatic light source 12, a full-color light source 13, and a linear light-distributing lens 14. The monochromatic light sources 12 are symmetrically arranged on both sides of the center line of the lamp panel 11, forming a matrix structure of monochromatic light source groups. The full-color light sources 13 are located on the center line of the lamp panel 11, forming a linear structure of full-color light source groups. The monochromatic light source groups and the full-color light source groups are arranged alternately and linearly on the lamp panel. The light-distributing lens 14 is installed parallel to the lamp panel 11 and is located at the front end of the lamp panel 11. The cross-sectional structure of the light-distributing lens 14 is a concave structure in the middle and a convex structure at both ends, that is, the light-distributing lens is a concave mirror structure and the two sides are convex mirror structures, so that it refracts the monochromatic light source 12 and the full-color light source 13. The light-distributing lens 14 is precisely coupled and matched with the full-color light source 13, and the luminous intensity curve and unfolding angle of the full-color light source 13 are redistributed according to the optical design requirements, so that the light emitted by the full-color light source 13 is unfolded. The light-distributing lens 14 maintains the light emission direction of the monochromatic light source 12, or concentrates the angle of the light emitted by the monochromatic light source 12.

[0013] Although the monochrome light source 12 and the full-color light source 13 use the same light distribution lens 14, the monochrome light source 12 and the full-color light source 13 are set in different positions. Through the refraction of the light distribution lens 14, different light distribution effects are obtained. In terms of human visual perception, the LED display formed by this pixel lamp presents a display effect with uniform full-color light distribution and soft light color, while the monochrome light is dazzling and bright with vivid light effect and color contrast.

[0014] In this embodiment, both the monochrome light source 12 and the full-color light source 13 are arranged in groups of four to six. Each group of monochrome light sources and the full-color light source group have the same number of light sources. The monochrome light sources 12 and the full-color light sources 13 are arranged alternately in groups. This arrangement results in a large number of monochrome light sources that are more concentrated, making the display effect bright and dazzling with more vivid color contrast, which can highlight the color of the monochrome light source 12.

[0015] In this embodiment, the monochromatic light source 12 is a single color such as gold, white, red, green or blue. The specific color of the monochromatic light source 12 can be set as needed. For example, gold is used to highlight a golden dragon or a golden phoenix; red is used to highlight flames; white is used to highlight the brilliance of diamonds, and so on.

[0016] In this embodiment, the initial light emission angle of the full-color light source 13 is 60 to 120 degrees (e.g., Figure 4 As shown), the light distribution lens 14 expands the angle to 180 to 210 degrees (as shown). Figure 5(As shown). The full-color light source 13 is a common type of light source. When expanded to 180 to 210 degrees, the full-color light distribution is uniform and the light color is soft. The monochromatic light source 12 also has an emission angle of 60 to 120 degrees, which is a common type of light source. However, the light distribution lens 14 does not change the emission angle of the monochromatic light source 12, or make the light of the monochromatic light source relatively concentrated. In this embodiment, the light distribution lens is a customized bat wing shape with a concave middle and convex ends. It can expand the light source located in the middle of the light distribution lens relatively evenly. However, for the monochromatic light source 12 that is off the center of the light distribution lens, it is gradually focused from one side of the middle of the light distribution lens 14 to one side of its edge. That is, the emission angle of the monochromatic light source 12 expands from a small angle near the middle of the light distribution lens, then remains unchanged, and finally focuses gradually.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
