1262353 IX. Description of the invention: [Technical field to which the invention belongs]

The invention relates to a light source device for an image display comprising an illuminator of one or a complex light panel, the light panel further comprising - or a plurality of solid-state light-emitting units having a high f-direction (four) ... the light panel comprises a height of the height The illuminating light is in an array of arrays, and no additional optical components are needed to align or illuminate the light emitted by the light panel. The invention also relates to the use of an illuminator in an electronic device such as an image display device, a rear projection television, a printer, a wiper, and a photocopier. [Prior Art] It is common to use a front projection lens or a large screen, and usually use a light source such as a (four) lamp or an arc lamp. Although such light sources have high luminance, they have the following disadvantages, such as high energy consumption, ancient operating temperature, insufficient color gamut, ultraviolet or infrared radiation, glass bulbs = bursting, large volume and weight, and long lighting. With switching time, shorter use of life, higher prices and environmental problems caused by the use of mercury. Therefore, such bulbs are usually only used where high brightness is required. Light-emitting directional semiconductor optical components such as Photonic Crystal Ught Emitting Di〇des (pc_LEDX), Laser Diodes (LD), and vertical cavity surface-emitting laser fields ( Vertical Cavity Surface Emitting Lasers (VCSEL) and other such sources are viable alternatives to these sources. Conventional light-emitting diodes use built-in focusing and diffusing optical elements, and have reflective optical elements in their outer package to achieve beam collimation and focusing. The first figure shows an optical package of a light-emitting diode disclosed in US Pat. No. 6,603,148, the disclosure of which is incorporated herein by reference. Inside 'Shi Xijiao! The i-type is covered by an upwardly convex hemispheric lens 13, and the light emitted from the side of the light-emitting diode (7) is reflected by the coated reflecting surface 14 to increase the overall optical collection efficiency. The package has a built-in coated reflective surface and a lens having a particular outer shape. The lens concentrates light and protects the light-emitting diode wafer. All of these additional optical packages account for the vast majority of the overall volume, while the reflective surface of the built-in = film and the lens construction with a special external shape are cost-effective to manufacture and are not easily aligned, thus resulting in a luminescence The functional performance of the diode to the other coil is inconsistent, and the distribution of the luminous flux output varies greatly between different light-emitting diodes. "The second figure shows a digital microlens (DMD) projector that is disclosed in U.S. Patent No. 6,644,814, which uses three separate light-emitting diodes. Array light source 1G, 丨3 and 1R (not = in Figure 2), green, blue, and red light from three light sources, respectively, through fly-eye lens 2G, 2B & 2R (not shown) Second), then pass through the second fly's eye lens and 3R, respectively, and then through a cross dichroic prism (DXP) 21 as a color combiner (C〇1〇r _biner) The white light is modulated and reflected by the optical elements 22, 23, 24, 2, and 2, and then by the digital microlens (DMD) panel 27. The modulated, reflected light is illuminated by a digital microlens (dmd). And 28 and the projection lens (pr〇jecti〇n lens) 29. Although this projector exhibits a good uniformity, but the volume and weight are too large, and when respectively emitted from three separate 1262353 LED array light sources The color beam passes through the separation and combination of cross-separation 稜鏡 (DXP) Caused by lateral color smearing of the projected image. The third figure is disclosed in US Patent Publication US Pub. Ν〇β 2004/0062044 "Illumination device and image projection device using the same". The utility model is composed of a small-plane light source 31, a columnar light leading member 32 and an angle position converting member 33. The lighting device further includes a A light modulation element 34 and a projection lens 35. Since the facet light source 31 has the characteristics of diffusion illumination, some of the larger color light beams cannot enter or propagate away. The columnar light guiding element 32. The reason why the columnar light guiding element 32 cannot be separated is that the color light beam has a large incident angle, so that repeated reflection in the columnar light guiding element 32 cannot be performed. Leaving. This will result in a reduction in the system's luminous flux output. Moreover, since each of the facet light sources must have a columnar light guiding element', the system is bulky. In the manufacturing cost and the production line is difficult to align. Figure IV is disclosed in U.S. Patent No. U.S · Pat. No · 6,517,211 "means a lighting element of the projection displays and projection displays." This system consists of three laser light sources 41G, 41B and 41R, three light guides 42G, 42B and 42R, three diffusive reflection surfaces 43G, 43B and 43R, three lights. Light integrator 44G, 44B and 44R, three concentrating lenses 45G, 45B and 45R, three light valves (light 1262353

ValVe) 46G, 46B and 46R, synthesizer Prism 47 and a projection lens element (pr〇jecti〇n membe) 48. In this 3-laser projection display, the angle of incidence from the laser to the diffuse reflection surface and the reflection angle from the no-reflection surface to the optical integrator have a limit (four), since the two limits the incidence of two large angles Light will not reach the light valve. This system is difficult to manufacture and align, and the light pipes it uses also lose light. In the light integral, there is a hole for causing light to be incident on the diffuse reflection surface from the t-ray, and the hole will cause light loss and long-term use, because the hole may become deteriorated after long-term use. At the office. An optical isolator placed between the laser source and the diffuse reflecting surface for preventing optical feedback problems causes an increase in cost and difficulty in manufacturing the display device. "The fifth figure shows the undressing of the US patent Pat. No. 6,547,421. The green light emitted from the green light source is led to the light valve by the green illuminating 〇ptical system 51G. Valve) 52G, and then through the cube separation 稜鏡 (cubk dichroicprism) 53, and reach the projection lens ((4) know (4) (10) iens) 54. Red and color light through this - system is also like green light. Cube color separation 稜鏡 53 combined Green, red, and blue light, and conduction of its synthetic light to the projection lens. Here, a conventional display device has a coupling lens such as a coupling lens and two rope eyes between the light source and the light valve. The lens (fly-e/ele曰ns) and the three concentrating lenses (c〇ndenseriens) make this optical system expensive and powerful, and it is difficult to become a compact device. Moreover, the luminous flux from the light source passes through After so many lenses, the system's light energy utilization efficiency and brightness are reduced. The six-figure diagram shows the "additional display device color gamut" disclosed in U.S. Patent 6, 648, 475 1262353. Method and apparatus", a green p-polarized green light is emitted from a green light source 6 1G, through a uniformizing optics 62G, a telecentric condenser lens 63G, a A dichroic mirror 64, a polarization beam-splitter 65G, and then reaches a reflective spatial light modulator (R-SLM) 66G. The modulated green The s-polarized green light is reflected by the reflective spatial light modulator and then incident on the polarized beam splitter 65G, which is then reflected by Lu to an intersecting cube (X-cube) 67 and then passed through a projection lens. (projection lens) 68, finally reaching a display surface 60. The blue-green light, the red light, and the blue light pass through the system as well as the green light. The cross-cube combines the modulated green light and the blue-green light. , red light and blue light, and combined light is sent to the projection lens. This conventional device uses four separate color light sources from different light paths. A method for the extended color gamut, using a large number of optical elements caused by system complexity, high cost, bulky, reducing the optical path length of light energy and light use efficiency of the system * degrees. Moreover, the length of the optical path also causes difficulty in adjusting the four optical paths to achieve color balance. As a result, a lateral color smearing phenomenon appears on the display surface. In short, increasing the durability, luminous flux and practicality of the light source is an urgent development goal, increasing the brightness, uniformity and light energy efficiency of the system, reducing the manufacturing cost and energy consumption, expanding the color gamut and dynamic color control, and realizing Small, light and colorful image display devices are areas that can be improved. 10 1262353 SUMMARY OF THE INVENTION The object of the present invention is to provide a luminaire, ((1) leg _ listening) or a light module, the illuminator or optical module comprising one or more light panels (light Panel) 'The light panel further comprises at least one solid-state light-emitting unit (solid_statelighting unit), wherein the light emitted by the sad light-emitting unit has a high directivity and an illuminating color, and the array consists of solid-state lighting units.
