Abstract

A luminaire comprises a relatively thin and flat light-emitting panel (1) having a light-emitting window (2) and, opposite said light-emitting window, a rear wall (3) with opposed edge surfaces (4, 14). At least one of the edge surfaces (4) is light transmitting and associated with a plurality of light sources (5, 5', 5"", ...). Light originating from the light sources (5, 5', 5"", ...) is spread in the panel (1). The invention is characterized in that a plurality of deformities (7, 7', 7'', ...; 8, 8', ...) is provided in the panel (1) for extracting light from the panel (1) via the light emission window (2). The deformities (7, 7', 7"", ...; 8, 8', ...) are clustered so as to form at least one light symbol (27; 28). The configuration of the clusters (17; 18) of deformities (7, 7', 7"", ...; 8, 8', ...) corresponds to the shape of the light symbol (27; 28). Preferably, the luminaire has a first and a second light-transmitting edge surface, with respectively, a first and a second plurality of light sources being associated with said surfaces. A first cluster of deformities only couples light from the first light source out of the panel, thereby forming a first light symbol, while a second cluster of deformities only couples light from the second light source out of the panel, thereby forming a second light symbol, independent of the formation of the first light symbol. The luminaire according to the invention provides independent lighting and coloring possibilities of light symbols in a single-panel luminaire.

Description

V. Description of the invention (1) The present invention relates to a light-emitting body including a light-transmitting panel including a light-emitting window; a back wall located opposite the light-emitting window; and an edge surface located on the light-emitting window At least one edge surface of the panel is transparent to the back wall, at least one light source is associated with the transparent edge surface, and during operation, light from the light source enters the transparent edge surface and is distributed on the panel. The invention further relates to a light-emitting panel used in a light-emitting body. For their part, such luminaries are well known and are also called edge lighting systems. In particular, this kind of luminous body is used in so-called luminous signs, which are used for advertising purposes. It can also be used in guidance boards such as "exit" signs, billboards, traffic lights, traffic flow systems, etc .; , And can be used as (instrument board) lighting in vehicles. This body can be further used as a backlight for a display device such as a liquid crystal display (LCD) device. This luminous body is used as internal lighting and external lighting. In this kind of light-emitting body, the light emitted by a lamp (such as a TL lamp) is used as a thin and flat panel in a light waveguide. The panel is made of ester, Perspe X (Pasper), and the light is lost. Text or marks (for example, in the process of carving, etching or appropriately providing scratches, a tubular low-voltage source is usually used, and the content is coupled after the operation, and the optical waveguide is made of synthetic resin, acrylic glass) PMMA's brand name under the effect of total internal reflection) is engraved in the way of diffusing light-emitting blocks. Alternatively, during the period of mercury vapor discharge, the light source tube is usually composed of: I; acid-based, polycarbonate, or glass materials that penetrate the panel light-transmitting waveguide. Carving is on the panel by mistake

Page 7 459213 V. Description of the invention (2) Provide a text or trademark by laying a (light scattering) layer. Alternatively, text or a logo is provided on the tape spread on the panel, and the tape may exhibit a difference in refractive index. This type of light emitter can also be equipped with a light source in the form of another optoelectronic element, also called an electro-optical element, for example, an electroluminescent element such as light emitting diodes (LEDs). These light sources are usually located near or close to the transparent edge surface of the panel, so that during operation, light from the light source enters the transparent edge surface and is distributed on the panel. The LED edge lighting system from DE-A 38 33 3 1 5 is well known. It includes one or more light-emitting diodes. The light-emitting diode system is coupled to the light-emitting panel through an optical waveguide to light up the light-emitting window. Light surface or light mark. The light surface or light mark provided is used as a light scattering layer on the surface of the panel, or as a light scattering groove in the surface of the panel. The aforementioned luminaires have several disadvantages. For example, only a part of the light in the panel that touches the light mark is coupled outside the panel, and in addition, a part of the light is emitted toward the back wall. In addition, light mark illumination is like a diffused light-emitting area. As a result, the attractiveness of the light-emitting body is weakened. °. In particular, the present invention aims to provide external coupling of light, and the purpose of the present invention is to eliminate the above-mentioned disadvantages of the luminous body mentioned in the first paragraph, in which a specific light distribution a is obtained. In order to achieve this, according to the invention The luminous body is characterized by a plurality of deformations on the board. Xiao Yi consumes the external light of the panel through the luminous window, and the deformations form at least ~ light marks after clustering, and

469213 V. Description of the invention (3) The configuration of the cluster is equivalent to the shape of a light mark. According to the method of the present invention, the attracting effect, attractiveness and attention value of the luminous body according to the present invention can be increased. In general, the term "deformation" as used in the description and patent application of the present invention refers to a device that can be used to couple light outside the panel. Distortion is a light structure with a predetermined geometry and size. Deformation can be used to couple light outside the panel in a well-defined way. The light is externally coupled in a predetermined direction, which also varies depending on the shape and location of the deformation on the panel. In particular, this means that an observer moving through the luminous body can see the light emitted by the luminous body according to the present invention "from its perspective" at a specific instant without having to look specifically toward the panel. The sudden appearance of light will attract the observer's attention and "force" the observer to see the luminous body. In turn, the luminous body's attention value is increased. Deformation acts as a secondary light source. An additional advantage of these deformations is that the deformed clusters can selectively emit light. Due to its advantages, different light marks can be lit independently and / or continuously. By lighting the light mark, or using control electronics, the associated deformations cluster the light outside the panel to obtain moving light objects (for example, people who seem to be walking), or by continuously lighting the letters, So that you can see the text. It is also possible to switch on and off various colored light sources in order to illuminate the light mark with various colors. In this method, the luminaire according to the present invention can obtain a dynamic lighting device having a high attention value. The advantage of these deformations is that more light is coupled outside the panel, which can guide the directional reflection of these deformations, thereby improving the brightness of the light emitter. In order to orient the light coupled outside the panel by these deformations, the deformed boundary surface is most

Yau, Description of Invention (4) It is better to have a specular reflection surface ', for example, an aluminum or silver reflective layer, or a reflective multiple coating. In another preferred embodiment, the deformed shape is plasticized so that in the deformation, total internal reflection causes light to be coupled outside the panel. An important advantage of total internal reflection as a method of coupling external light to the panel is that it is not necessary to provide a reflective surface for the deformed part. According to the known illuminant, when the incident diffuse reflection light is reflected back and forth in the panel, it will be emitted in all directions, for example, it will also be emitted in the direction of the back wall. As a result, the brightness of the luminous body in the lateral direction of the panel is lower than that of the light source, which reduces the attractiveness of the luminous body. Note that it is known to provide a plurality of deformations to couple external light from the luminaire. In such edge lighting systems, a plurality of so-called "deformation" or "disruptions" light absorption devices are provided on the light-emitting panel. The shape and / or size of these deformations may gradually change, and / or the distance between the deformations on the panel may gradually change β. However, the purpose of such edge lighting systems is to 'get as uniform a light distribution as possible, especially these systems A lighting panel used as a (flat) display device, for example, a liquid crystal display device. The light distribution of the luminous body according to the invention is intentionally heterogeneous and inconsistent. (Dynamic) deviations from homogeneous and consistent light-emitting panels can increase the attention value of the light-emitting body. "A preferred embodiment of the luminous body according to the present invention is characterized in that at least the first and second edge surfaces are transparent, at least one first light source is associated with the first transparent edge surface, and at least one second light source is associated with the first Two light-transmitting edge surface associations, and during operation, the first deformation cluster couples light originating from the first light source

V. Description of the invention (5) line in order to form the first light mark, and in the order of the operation process, the second deformation cluster consumes the light from the second light source to form the second light mark. In the known light-emitting body, only a specific light mark (for example, the letter "P") 'or a light mark set (for example, "ACCESS DENIED") can be lighted at a specific position on the panel. In the foregoing specific embodiment of the light-emitting body according to the present invention, two independent light marks (for example, the letter “E” and the letter “A”) may be lit on the panel, or two light mark sets may be lit. (For example, "EXIT" and "NO ENTRY") In addition, these light tokens or light token sets may partially or completely overlap. In this way, the specific embodiment can switch from a certain character to other characters. You can also add text to the existing text (for example, "NO ENTRY" instead of "ENTRY"). The name or trademark of the opening or closing body has a different name. It is colored in yellow to match the light source. And, generally, This type of occupation is arranged in a descriptive manner, or, by marking the name of the trademark 'and according to the requirements, the two sets of light signs according to the present invention may also be blue to lighten the text or the trademark and / or the crown is red And / or the cluster is associated with the first light source to deform the cluster and the second or other rabbit light body can increase the amount of attention by substantially increasing the amount of illumination. Must be, for example, parallel to each other to be able to light independently of each other. Attached light mark. In the embodiment, two light marks or colors are used (for example, lit with green and / or stars on the text or brand name). By deforming the first 'and by consuming the light by the second or the other, in this way, the light-emitting windows of the' plurality of panels' according to the present invention are generally increased so that they appear to be overlapping light recording spaces and require Many materials

Page 11 5 'Invention Note (6) The panel stack is quite bulky and bulky and therefore very expensive. To ensure that light is coupled outside the panel so that it can move in a specific direction, it is best to place a deformation on the back of the panel. If the light reflected back and forth from the panel enters the deformation or light structure 'in the back wall, it will be reflected, causing the light to be transmitted toward the light emitting window' and leaving the panel located in the light emitting window. In another embodiment, deformation is provided on a light-emitting window of the panel. These deformations may have, for example, a lens structure. The deformed shape, size, and location affect how light leaves the panel. For example, a preferred embodiment of the luminous body according to the present invention is characterized in that the deformed shape is selected from the group consisting of a triangular prism, a tetrahedron, a quadrangular pyramid, and a cone. This type of shape is ideal for coupling light from a light emitter in various ways. It may be very suitable to use the deformation in the form of a triangle, so that the light can smoothly travel in a certain direction, and couple the light outside the panel and its lateral direction. The preferred embodiment of the luminous body according to the present invention is characterized in that the deformation is a triangular ridge, and the sides of the triangular ridge are transverse to the back wall. If the deformation constitutes a part of the first deformation cluster, during operation, the edge The prism of the mirror extends in the lateral direction of the light emitted by the first light source, and if the-part @ that deforms to form the second deformed cluster, during operation, the prism of 稜鏡 extends in the lateral direction of the light emitted by the second light source. In this specific embodiment, the triangular prism is located on the side of the back wall of the panel. The following effects will occur in the illustrated specific embodiment. The light from the first light source is reflected from the side of the first deformation cluster, and from the second light source

Page 12

2. The light of invention description (7) passes through. Please note that the upper surface for the sake of time is derived from the first shot, and from the upper surface and the bottom to form the first cluster. These deformed light sources are then two light rays that make up different colors. In this method, light emitters are used. In this case, the dynamic lighting is developed, for example, ‘if the light source associated with the surface is directed toward the respective light source, it ’s raining. As for the triangle surface, then the ‘C9 ® H first deformation group is easy to understand, the surface and the lower layer surface—the layer surface of the first light source of the light source constitutes and points & the deformation deformation to form and light up the deformation cluster ^. In addition, the line, you can get the extraordinary method, borrow, f〆 0A, especially. The surface of the luminous body is reversed, and for the shadow panel that disperses the luminous lines, each side of the prism sets the upper surface of the prism. Through the second variation, only the first light will be turned on to couple the light marks outside the panel. Also the light marks outside the panel. If the external light is coupled first, the second light will be coupled. If the first light is on, the absorption and the second light have different color effects, and the light source is highly switched. Then the light, the ground, and the line can be hit at the same time, so that the light can be attracted to the surface by coupling colorful light. Column of. The opposite side is the only way to construct the side. There are two ways to open the side to mark the panel. The value has a triangle, which has three triangular prisms extending laterally in the process of working with the edges of the three sides. In this case, a part of the light emitted by a ringing light source helps to use a tetrahedron Deformation of form. The surface is related to one of the edge surfaces of the panel. It is especially suitable for the upper surface and lower surface of the concrete. It is transverse to the back wall.

459213 V. Description of invention (8). Or the light reflected from the surface between the lower layers is medium. Such light rays have the side of the prism presenting the protected light-emitting panel of the present invention. See below for more and other points. In the diagram: Figure 1 A shows according to Figure 1 B shows Figure 1 A Figure 2A shows according to the plan view; Figure 2B shows Figure 2A and by virtue of this, because light is transformed on this class of J = = The upper surface or clothing surface of the mirror exudes in the same but opposite directions. The layer table cannot be consumed outside the panel. Its further mega volume, Jie Ye, is suitable for the case of total internal reflection. The specific examples of the detailed description of the deformation can be understood, and the scope also includes a cross-section of a specific embodiment of the luminous body used in the luminous body such as this specification and the patent application of the present invention. _, The front view of the luminous body shown; ^ the ring type of another specific embodiment of the luminous body of the present invention is broken; the detailed embodiment of the luminous body shown is shown in FIG. 3 in the form of a triangle 稜鏡Light rays path. The drawings are purely schematic, not drawn on a scale. In particular, some deformations are deliberately exaggerated in order to be easily solved. In the drawings, similar reference numerals represent similar parts as much as possible. FIG. 1A shows a cross-sectional view of a specific embodiment of a light emitting body according to the present invention. The light emitter contains a panel of a light transmitting material. Panel 1 is made of synthetic resin, acrylic acid, polycarbonate I, perSpex

Page 14 4b92l3 V. Description of the invention (9) PMMA or glass is made of materials. During operation, light penetrates the panel 1 under the influence of total internal reflection. The panel 1 has a light-emitting window 2 and a back wall 3 located opposite the light-emitting window 2. There are edge surfaces 4, 14 between the light-emitting window 2 and the back wall 3. In the example of FIG. 1A, the edge surface 4 is transparent, and the light sources 5, 5 ', 5 ", ... are associated with the edge surface 4. In this example, the light sources 5, 5 ', 5 ", ... include a plurality of light emitting diodes (LEDs)'. However, the different light sources may also be discharge lamps or (usually) a plurality of optoelectronic components, and also It is called an electro-optical element, such as an electroluminescent element. The source brightness of LEDs is many times higher than the source brightness of fluorescent tubes. In addition, when LED materials are used, the efficiency of coupling light inside the panel is better than that of fluorescent tubes. The advantage of using an LED as a light source is that the LED can abut a panel made of synthetic resin. LEDs emit almost no heat and no harmful (ultraviolet) radiation. An additional advantage of using LED is that there is no need to couple the light source from the LED inside the panel. The use of LEDs further reduces the size of the luminous body. In order to obtain a luminous body of high attention value, so-called LED power units can be used as the material. For example, 'Barracudaj-type (Hewlett-Packard) high-efficiency, high-output LEDs can be used. Luminous flux per LED: Red LED is 10 lumens (1 m), green [£ d is 13 lumens (1 m). Use these high The unique advantage of high-efficiency, high-output LEDs is that 'the number of LEDs required is relatively small for the relatively high level of light output desired. Therefore, smaller and more cost-effective light emitters can be manufactured. In another specific embodiment, use

"Barracuda" type (Hewlett-Packard) high efficiency, high output LED, in this case, the luminous flux per LED: red [rib is ⑵lumen

Page 15 Λ 5 V. Description of the invention (ίο) (lm), the green LED is 30 lumens (U). By using LEDs as light sources, luminous bodies visible in the picture can be obtained. The 7C degrees of these luminous bodies can be beautiful or better than the luminous bodies based on the light generated by fluorescent tubes or camp lights. LEDs are best mounted on metal chip core printed circuit boards ^ If power LED (power LED) is mounted on such metal sheet core printed circuit boards (11161 ^ b core printed circuit board; MC-PCB), then It is easy to dissipate the heat generated by the LED through the heat conduction of the PCB. A specific embodiment of the light emitting body includes a housing accommodating the LED 'which is made of a metal material and equipped with a cooling fan, and in this embodiment, the metal core printed circuit board contacts the metal housing via a thermally conductive connection. This type of thermally conductive connection is best constructed by mounting on a metal panel connected to a metal case ... ^ ". The heat generated by the LED can be conducted by MC-PCB (thermal) conduction, connected to the metal panel of the case, and a cooling fan To dissipate the heat, so that the heat can be dissipated to the surrounding environment. The advantage is that it does not require forced air cooling to eliminate the heat, as is the case in known illuminants. During operation 'from the light source 5,5' 5 ..., the light is coupled in the panel 1 via the light-transmitting edge surface 4, and the light is distributed on the panel 1. According to the principle of total internal reflection, the light continues to move back and forth in the panel 1 unless (for example) by deformation Coupling light outside the panel. Opposite the light-transmitting edge surface 4 is the edge surface 14, which is preferably provided with a reflective coating (not shown in Fig. 1A) 'in order to absorb the light source 5, 5, 5 "inside the panel, ... the light. Without the use of a reflective coating, an attractive edge surface can be obtained. In another specific embodiment, two opposite edges

Proper combination of mirror inversion 4+ deformation is a preferred embodiment of diffusion inversion. With the ball continuing to eight, the hall has determined that, st, 4 * # β ^ is wrongly composed of 4, and S achieves the lighting effect of showing off. For example, a light sign capable of absorbing attention can be used in the 'expansion reflection first sign'. The distortion in the panel acts as a secondary light source. The light source may be associated with a specific optical system this time, for example, this optical system is available on the light-emitting window (not shown in Figure 丨 A). The optical system may be used to form a parallel beam β. Fig. 1 A shows the light source from the light source 5, 5, 5, 5 11, ..., a light ray in a schematic view.

The number of sides of such deformation can be supplemented by: The number of edge surfaces varies depending on the number of panels, and one or one is soiled. Aggregation Surface association. With the far edge of the cone (not shown in the figure), the light from all directions is not shown) This is enough to light the outside of the panel. It is very suitable for the deformation in the form of a triangular prism, so that the light can travel smoothly in a certain direction.
