1. Field of the Invention
The present invention relates to projectors and more particularly pertains to a new projector with light emitting diodes for projecting images with less heat being generated.
2. Description of the Prior Art
The use of projectors is known in the prior art. More specifically, projectors heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural, configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
The prior art includes a light emitting diode (LED) light source comprising an LED die, or a closely packed die array or matrix of die arrays, substantially and efficiently coupled to non-imaging collection optics. The non-imaging collection optics operate to provide a homogenized LED output having a near field whose intensity is highly uniform and a reduced far field extent substantially preserving the etendue (area, solid angle, index squared product) of the LED output. The near field, in turn, is imaged by a downstream relay lens to an illumination plane a specific distance away. Another prior art includes a multi colour LED, in which layers for generating light of different colors are arranged one above the other, is used as the light source in a projector. While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new projector with light emitting diodes.
The general purpose of the present invention which will be described subsequently in greater detail, is to provide a new projector with light emitting diodes which has many of the advantages of the projectors mentioned heretofore and many novel features that result in a new projector with light emitting diodes which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art projectors either alone or in any combination thereof. The present invention includes a housing having side walls and front and back end walls and a first opening extending transversely through the front end wall and an image projecting assembly including a mirror disposed in the housing, a light source spatially arranged relative to the mirror and adapted to reflect an image off the mirror, and a lens assembly aligned with the first opening in the housing to project the reflected image outside the housing. None of the prior art includes the combination of the elements of the present invention.
There has thus been outlined, rather broadly, the more important features of the projector with light emitting diodes in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
It is an object of the present invention to provide a new projector with light emitting diodes which has many of the advantages of the projectors mentioned heretofore and many novel features that result in a new projector with light emitting diodes which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art projectors, either alone or in any combination thereof.
Still another object of the present invention is to provide a new projector with light emitting diodes for projecting images while less energy and generating less heat.
Still yet another object of the present invention is to provide a new projector with light emitting diodes that provides more linear and even lighting rather than scattered lighting from incandescent bulbs to effectively project the image.
Even still another object of the present invention is to provide a new projector with light emitting diodes positioned at a particular angle relative to a mirror to effectively and efficiently project the image.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses. reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the shove description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the projector with light emitting diodes. Further, since numerous modifications and chances will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
