Abstract
For illuminating an object and generating a light image, e.g. for presentation of the object, an illumination assembly comprises a reflective part for illumination and a diffractive part for generating the light image. A light source such as a LED Light source is used for generating the light.
Description
- The present invention relates to an illumination assembly for illuminating an object.
- In a shop, products are stacked in a rack, or the like, and presented to a customer. In order to attract the attention of the customer, the products should be clearly visible. Further, preferably, also other signs are provided for attracting the attention of the customer. Such a sign may provide information about the product, the price of the product or other relevant information, for example.
- In JP2006071690 it is described to use an image-creating body and a light emitting diode (LED) to project a light image on a first side of a translucent screen, thereby generating a shadow image on a second side of the translucent screen. Thus, using a text, a brand mark or the like may be shown as a light image.
- It is an object of the present invention to provide an illumination system for illuminating an object and for generating a light image.
- The object is achieved in an illumination assembly according to claim The illumination system comprises at least one light source, such as a LED, for generating light. The light source is arranged such that a part of the generated light is directed at a reflective part of the illumination assembly. The reflective part is arranged and configured to illuminate the object, such as an article for sale or a wall. Further, the light source is arranged such that another part of the generated light is directed at a diffractive part. The diffractive part is configured to shape a distribution of the light, thereby generating a light image.
- The reflective part may comprise a reflector to reflect the light generated by the light source and/or the reflective part may comprise a diffractive reflective part to re-direct the light. For example, a diffractive reflective part may be used to generate a light spot directed at a particular product on a shelf.
- In an embodiment, the reflective part may comprise a second light source. The second light source may be, for example, a reflective OLED (organic light emitting diode), thereby generating more light and illuminating the object even more.
- The diffractive part may comprise a transmissive diffractive element such that light generated by the light source may pass through the diffractive element. A person positioned on a side of the diffractive element opposite of said element compared to the light source may perceive a three-dimensional image, when looking at the diffractive element.
- The diffractive part may comprise a reflective diffractive element for generating a three-dimensional light image on the object. The object may be, for example, a wall. As mentioned above, it may also be used for highlighting a product on a shelf, or the like.
- Hereinafter, the present invention is elucidated with reference to the appended drawings showing non-limiting embodiments, wherein:
-
FIG. 1 shows a first embodiment of an illumination assembly according to the present invention; -
FIG. 2 shows a second embodiment of an illumination assembly according to the present invention; -
FIG. 3 shows a third embodiment of an illumination assembly according to the present invention; -
FIG. 4 shows a fourth embodiment of an illumination assembly according to the present invention; -
FIG. 5 shows a fifth embodiment of an illumination assembly according to the present invention; and -
FIG. 6 shows a sixth embodiment of an illumination assembly according to the present invention. - In the drawings, same reference numerals refer to same elements.
FIG. 1 shows anillumination assembly 10 arranged relative to a display D of products. The products are arranged on shelves, for example. Theillumination assembly 10 comprises alight source 12, for example a LED light source, for generating light. Theillumination assembly 10 further comprises areflective part 20 comprising areflector 22 and adiffractive part 30 comprising a transmissivediffractive element 32. Further, an eye E of a person, e.g. a customer, is shown, Also, an image I is shown. The image I is a virtual image that may be perceived by the person, as is elucidated below. Arrows A represent exemplary light ray trajectories. - In operation, the
illumination assembly 10 illuminates the products on the display D. To achieve this, the light generated by thelight source 12 is reflected by thereflector 22. Thereflector 22 is shaped such that substantially the whole display D, or a predetermined part thereof, is illuminated as illustrated by the arrows A. Further, a part of the generated light passes through the transmissivediffractive element 32. A part of said light reaches the eye E and the image I is perceived by the person. The image I may be a three-dimensional image of a logo, a brand name, a trademark or any other sign, for example. -
FIG. 2 shows a second embodiment of theillumination assembly 10. Compared to the first embodiment illustrated inFIG. 1 , the reflective part of the second embodiment is provided with a diffractivereflective element 24. The diffractivereflective element 24 may replace thereflector 22 or may be used in combination with thereflector 22. The diffractivereflective element 24 enables more accurate shaping of the reflected light and thus the illumination of the display D. -
FIG. 3 shows a third embodiment of theillumination assembly 10. Compared to the first embodiment illustrated inFIG. 1 , the reflective part of the third embodiment is provided with a reflective organic light emitting diode (OLED) 26, or a number ofOLEDs 26. TheOLEDs 26 generate additional light, thereby enabling better illumination of the display D. Moreover, since the display D receives light from theOLEDs 26, thefirst light source 12 may transmit more light through thediffractive element 32, thereby obtaining a brighter image 1. Thereflective OLEDs 26 may be used instead of, or in combination with, thereflector 22 and/or the diffractivereflective element 24. -
FIG. 4 shows a fourth embodiment of anillumination assembly 10. Theillumination assembly 10 is configured to illuminate a wall W and to project an image I on the wall W. Of course, the wall W may as well be a display D, or the like. In the fourth embodiment, a suitablyshaped reflector 22 is used to illuminate the wall WA reflectivediffractive element 34 is used to generate the image I on the wall W. -
FIG. 5 shows a fifth embodiment of theillumination assembly 10. Compared to the fourth embodiment, thereflective part 20 comprises a reflectivediffractive element 24 instead of, or in combination with, thereflector 22. As illustrated inFIG. 6 , thereflective part 20 may further comprise areflective OLED 26, or a number ofreflective OLEDs 26. - Although detailed embodiments of the present invention are disclosed herein, it is to be understood that the disclosed embodiments are merely exemplary embodiments of the invention, which can be embodied in various forms.
