Embodiment Construction

[0090] The core point of the present invention is that when a plurality of light spots or light sources form an image array of light spot gaps, optical reduction is carried out through optical elements to reduce the size of the optical surface of the image after the light spots or light sources pass through the optical elements, and at the same time the light spots or The gap between the light sources passes through the optical elements, and the image light spots or the gaps between the light sources are also proportionally reduced. When the image light spots or the gaps between the light sources are small, the light spots themselves are also focused to increase the brightness of the light spot size. Reduced light point optical image, due to the diffusion effect of such light point optical image when it is imaged on an imaging component with a diffusion effect, such as a projection screen, the gap between adjacent luminous light points in the light point optical image is diffuse...

Abstract

The invention provides an illuminating system, comprising the following parts: a lattice luminescent display unit and a first optical element, wherein, the light emitted from the lattice luminescent unit is optically collected by the first optical element on a first image-forming block with scattering effect to generate a first optical illumination. A second optical element is comprised when in actual needs, the first optical illumination output is optically enlarged or diminished by the second optical element to generate a second optical illumination output; by adjusting the focus of the first optical element or the distance between the lattice luminescent display unit and the first optical element, the space among the luminous spots of the formed first optical illumination is less than the size of the luminous spots and no gap exists among the luminous spots in the first optical illumination. By adopting lattice illuminating source and forming single light source illuminating effect through optical processing, the system has the advantages of higher reliability and lower price.

Description

technical field [0001] The invention relates to a lighting system, in particular to a lighting system realized by using an LED dot matrix array. Background technique [0002] LED lights, also known as solid-state light-emitting devices, can be made smaller because of their long service life, and their brightness can be controlled by controlling the current loaded on the LED lights, and the LED lights can have multiple colors. Therefore, LED lights are used as image display devices, which are widely used in large-screen advertising systems and large-screen TV receiving systems. [0003] However, because the LED lights need to be fixed on the circuit board to form an LED light array, there are gaps between the LED lights. When people watch the image displayed by the LED array at a relatively close distance, they will see obvious pixel interval areas, resulting in blurred images. Problem with low image quality. [0004] Similarly, in a cathode ray tube display based on a fluo...
