Organic light system

RELATED APPLICATIONS

This application claims priority from taiwan patent application No. 108129185, filed 2019, 8, 15, the entire disclosure of which is incorporated herein by reference in its entirety.

Technical Field

The present invention relates to lighting technology, and more particularly to an organic lighting system.

Background

In today's society, a vehicle is not just a vehicle, but more likely an office or other home, another living area. Therefore, many people have bright demands for the interior space of the car, such as for example make-up, reading, even friendship, and the like.

However, conventional interior lighting fixtures often fail to meet such requirements, sometimes with insufficient brightness and sometimes too harsh. Therefore, there is a need for a lighting system that can be used in a vehicle to protect the eyes and provide sufficient brightness.

Disclosure of Invention

The invention provides an organic light system which is used for a vehicle. The organic light system may include an organic planar light source having a light emitting surface that emits light within the vehicle. The organic lighting system may further include a lamp assembly surrounding the organic planar light source, wherein the lamp assembly is connected to the vehicle body. The organic lighting system may further include a movable cover plate partially covering the organic flat light source and connected to the lamp body assembly.

The lamp body assembly does not need to be used for accommodating a plurality of traditional lamp bodies of point-shaped luminous bodies in space, and only needs to be used for accommodating one organic plane light source. The organic plane light source can have a continuous, soft and even luminous surface. The light emitted by the organic light system is soft, not dazzling and relatively uniform, so that the brightness of the organic light system can be brighter than that of a traditional light source.

The movable cover plate may include four edges, any three of which may be separated from the lamp assembly, such that the movable cover plate may be partially separated from the lamp assembly. Alternatively, the movable cover plate may be an openable cover plate.

The organic light system of the present invention may further comprise a circuit assembly electrically connected to the organic planar light source. The organic lighting system of the invention can further comprise a connector, so that the circuit assembly is electrically connected with the vehicle power supply. The organic light system can be a cosmetic mirror lamp, a reading lamp, an atmosphere lamp or a trunk lamp.

Thus, with the structure of the above embodiment, the lamp body assembly of the organic lighting system does not need to accommodate a plurality of lamp bodies of the traditional point-shaped luminous bodies in space, and only needs to accommodate one organic plane light source. The organic planar light source can have a continuous, soft, uniform light emitting surface. In addition, the light emitted by the organic light system is soft, not dazzling and relatively uniform, so that the brightness can be brighter than that of the traditional light source.

The foregoing is merely illustrative of the problems to be solved, the technical solutions to the problems, and the effects that can be produced thereby, and the details of the present invention will be described in the following embodiments and the related drawings.

Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, these implementation details are not necessary in the embodiments of the present invention. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

It will be understood that, although specific terms such as "first," "second," etc. may be used herein to describe various elements, spaces, or regions, these elements, spaces, or regions should not be limited by these terms. These terms are used to distinguish one component, space, or region from another component, space, or region. Thus, a first element, space, or region described below could be termed a second element, space, or region without departing from the spirit and scope of the present invention.

Spatially relative terms, such as "within …," "between …," "about …," "above …," and the like, are used herein to facilitate describing the relationship of one element or feature to another element or feature. It will thus be appreciated that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "on" other elements or features would then be oriented "under" the other elements or features. Thus, these exemplary terms "on …" may encompass both an upper and lower orientation. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein should be interpreted accordingly.

It will be understood that when an element is referred to as being "on" or "connected" to another element, it can be directly on or connected to the other element or intervening elements or layers may be present. In addition, it will be understood that when an element is referred to as being "between" two elements, it can be the only element or layer between the two elements, or one or more intervening elements or layers may also be present.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a", "an" and "the" include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, "and/or" includes any and all combinations of one or more of the associated listed words. When a list of elements is preceded by a term such as "at least one of …," the entire list of elements is modified rather than modifying the individual elements of the list.

FIG. 1 is a schematic diagram illustrating a first method for using an organic light system according to a preferred embodiment of the invention. Referring to fig. 1, the organic light system 150 of the present invention may include an organic flat light source 102, a lamp assembly 130, and a movable cover plate 140. The lamp body assembly 130 may surround the organic planar light source 102. The movable cover plate 140 may partially cover the organic flat light source 102.

FIG. 8 is a schematic diagram of an organic light system used in a vehicle according to a preferred embodiment of the invention. Referring to fig. 8, the organic light system of the present invention can be used in a vehicle 500. The vehicle 500 may include a body 800 and a vehicle power supply 802. The organic light emitting system 150 may be connected to the vehicle body 800. The organic light emitting system 150 may be connected to the vehicle body 800 in various ways; one is embedded, one is external, and can also be electrically connected, or mechanically connected, or a combination of the above four ways, depending on various needs in the vehicle 500. The location of the organic light emitting system 150 within the vehicle 500 is also contingent on various needs. The organic lighting system of the present invention may also be a vanity mirror light, reading light, atmosphere light, or trunk light, depending on the location or need.

Referring to fig. 1, the organic planar light source 102 is different from a conventional light source composed of point-like light emitters. Each lamp body of the conventional point-shaped luminous body needs space, so the luminous surface of the conventional light source is limited by the occupation of the space by a plurality of lamp bodies, and a continuous and uniform luminous surface cannot be formed under the discontinuous condition.

With reference to fig. 1, the organic flat light source 102 of the present invention has soft and non-glare light and is relatively uniform, so that the brightness can be brighter than that of the conventional light source. Therefore, the organic planar light source 102 of the present invention can have a continuous, soft, and uniform light emitting surface 100. The movable cover plate 140 may have a light-transmitting region 142 to expose the light-emitting surface 100, so that the light-emitting surface 100 can emit light toward or in the vehicle. The light emitting color may be white light, red light, blue light, pink light, etc., but not limited thereto. The Organic planar Light source 102 may be an Organic electroluminescent (Organic electroluminescent) Light source, such as an Organic Light-Emitting Diode (OLED) Light sheet.

With continued reference to fig. 1, the lamp body assembly 130 surrounds the organic planar light source 102, and may be, but is not limited to, surrounding the periphery of the organic planar light source 102. For example, the lamp body assembly 130 may provide an accommodating space 132, and the accommodating space 132 may be slightly larger than the organic planar light source 102, but substantially conformal to the organic planar light source 102. At this time, the organic planar light source 102 can be stably placed inside the lamp body assembly 130. It should be noted that the shape and size of the accommodating space 132 are not limited to the above examples, and the organic planar light source 102 can be stably placed without departing from the scope of the invention. On the other hand, the accommodating space 132 may accommodate not only the organic light source 102 but also the movable cover plate 140, so that the movable cover plate 140 is not visible when the lamp body assembly 130 is viewed from the side, as shown in fig. 5. However, the lateral area of the movable cover 140 may be slightly larger than that of the accommodating space 132. Thus, even if the lamp body assembly 130 is turned upside down, the movable cover plate 140 can still be stably placed in the accommodating space 132, and the organic planar light source 102 is ensured not to fall out. Furthermore, during the traveling of the vehicle, the lateral area of the movable cover 140 is slightly larger than that of the accommodating space 132, so that the movable cover 140 does not shake, which is helpful for the stability of the movable cover and the organic planar light source 102.

Referring to fig. 1, the movable cover 140 may be partially separated from the lamp assembly 130. FIG. 7 is a partially exploded view of an organic light system according to a preferred embodiment of the invention. Referring to fig. 7, the movable cover plate 140 may include four

edges

140a, 140b, 140c, 140d and four

ends

145a, 145b, 145c, 145 d. Any three adjacent edges (e.g., 140a, 140b, 140c) can be separated from the lamp body assembly 130, so that the movable cover plate 140 can be partially separated from the lamp body assembly 130. The movable cover 140 may also be entirely removed from the lamp body assembly 130, if desired. Alternatively, the movable cover plate may be an openable cover plate.

Referring to fig. 7, each of the

terminals

145a, 145b, 145c, 145d may be an outwardly protruding bump or a pivot device. When each of the

terminals

145a, 145b, 145c, 145d is an outward protruding bump, the four

terminals

145a, 145b, 145c, 145d can respectively abut against the four ends of the organic planar light source 102, so as to improve the stability thereof. The abutting method can be two methods, one is to press the organic planar light source 102 into the accommodating space 132, and the other is to slightly buckle four ends of the organic planar light source 102. Portions of the end points (e.g., 145c, 145d) can exit the lamp body assembly 130, as shown in fig. 1. Referring to fig. 1, for example, the

terminals

145c and 145d may be separated from the lamp body assembly 130, so that the movable cover plate 140 may be partially separated from the lamp body assembly 130 and not fixed in the lamp body assembly 130. More specifically, two adjacent ends (e.g., 145c, 145d) of the four ends can be separated from the lamp body assembly 130, and the border line formed by the connection of the other two

adjacent ends

145a, 145b and the lamp body assembly 130 nearby can form a rotation mechanism, so that the movable cover plate 140 can rotate along the border line, and the movable cover plate 140 can still be partially connected to the lamp body assembly 130.

For another example, referring to fig. 2, the

ends

145a, 145b can be separated from the lamp body assembly 130, so that the movable cover plate 140 can be partially separated from the lamp body assembly 130 without being fixed in the lamp body assembly 130. More specifically, two

adjacent ends

145a, 145b of the four ends can be separated from the lamp body assembly 130, and the border 146 formed by the connection of the other two

adjacent ends

145c, 145d and the lamp body assembly 130 nearby can form a rotation mechanism, so that the movable cover plate 140 can rotate along the border 146, and the movable cover plate 140 can still be partially connected to the lamp body assembly 130.

Referring to fig. 2, after the movable cover plate 140 is partially or entirely separated from the lamp body assembly 130, the organic flat light source 102 can be placed or replaced. For example, the organic planar light source 102 may be disposed in the accommodating space 132. Alternatively, after the organic planar light source 102 in the lamp body assembly 130 is taken out, another organic planar light source 102 may be placed. After the organic flat light source 102 is placed inside the lamp body assembly 130, the movable cover plate 140 may be covered again, as shown in fig. 3. FIG. 3 is a schematic front view of an organic light system according to a preferred embodiment of the invention. FIG. 6 is a perspective view of an organic light system according to a preferred embodiment of the invention.

Referring to fig. 9, the organic light system 150 of the present invention may further include a connector 120 for electrically connecting the organic planar light source 102 and the vehicular power supply 802. There may be a connection 300' between the connector 120 and the organic planar light source 102. The connection 300' may be an electrical connection or a mechanical connection. Additionally, there may be a connection 200' between the vehicle power supply 802 and the connector 120. The connection 200' may be an electrical and/or mechanical connection. Referring to fig. 12, a front view of the connector 120 is shown in fig. 12, which is a schematic front view of the connector 120 of fig. 9 according to the preferred embodiment of the invention.

Referring to fig. 7, the organic light emitting system of the present invention may further include a circuit assembly electrically connected to the organic planar light source 102. The Circuit assembly may be a Flexible Printed Circuit Board (FPCB) 300 or a rigid Printed Circuit Board (PCB) 307. The flexible circuit board 300 may also be the connection 300' shown in fig. 9. The lamp assembly may further include a through hole 305 for allowing the flexible circuit board 300 to pass through and electrically connect to the vehicle power supply 802, as shown in fig. 9.

Referring to fig. 1, the organic planar light source of the present invention may include at least one anode contact 100a and at least one cathode contact 100 b. The position of the positive contact 100a and the at least one negative contact 100b may be planned according to various needs. One of the planning methods is to arrange all the organic planar light sources on one edge 102a of the four

edges

102a, 102b, 102c, 102d, as shown in fig. 1, but not limited thereto. Referring to fig. 1, the negative contacts 100b may be disposed on the left and right sides of the positive contact 100a, for example.

FIG. 11 is a schematic diagram of the circuit board internal circuitry 302 of FIG. 10 according to the preferred embodiment of the invention. Referring to fig. 11, the internal circuitry 302 may include a rectifier bridge diode D1 for Reverse Voltage protection (Reverse Voltage protection). Referring to fig. 12 and 11, it is to be noted that the left and right contacts V in fig. 11 are connected to the left contact 12a or the right contact 12r of the connector 120 in fig. 12, respectively, or vice versa, so as to ensure the normal operation of the organic light emitting system without short circuit problem. Fig. 13 is a perspective view of the connector 120 of fig. 9 according to the preferred embodiment of the invention. Fig. 14 is a side view of the connector 120 of fig. 9 according to the preferred embodiment of the invention.
