- the electromagnetic radiation assembly 10 of the present invention and which is shown and described herein, is discussed as it would be configured if it was installed on an overland vehicle 11 of conventional design.
- the electromagnetic radiation assembly (hereinafter referred to as assembly 10) of the present invention is adapted to operate as a combination rearview mirror and visual signaling device, and wherein the visual signaling device provides a visual signal which is capable of being seen from locations which are laterally and rearwardly of the overland vehicle 11 , when the invention is operating in a first mode.
- the visual signal at a significantly reduced intensity, can normally be seen by the operator of the same vehicle.
- the invention when operating in a second mode, is operable to illuminate the side, and region adjacent to the overland vehicle, in order to assist an operator or passenger when they are entering or exiting the vehicle during reduced periods of visibility.
- the assembly 10 of the present invention is mounted on an overland vehicle 11 of conventional design.
- the overland vehicle 11 has a front or forward portion 12, and a rearward portion 13.
- the overland vehicle 11 further has a passenger compartment 14 which includes a front seat 15.
- the overland vehicle 11 has a longitudinal axis which is generally indicated by the numeral 16, and an operator's position 20.
- the overland vehicle also includes locations 21 for a pair of exterior rearview mirrors.
- the overland vehicle 11 also has a hand operated directional signaling switch; and brake (not shown), and which when utilized, provides an electrical signal which may alert drivers of other vehicles in the immediate vicinity that the overland vehicle 11 is about to change directions, turn, change lanes, etc. Yet further, other signals may also be provided from the overland vehicle from other devices such as a hazard warning switch.
- the overland vehicle 11 may be equipped with a radio frequency receiver 22 and which receives an RF signal which is transmitted from a key fob held by the operator of the overland vehicle (not shown).
- This radio signal is operable to unlock the various doors of the overland vehicle, and further, is useful in actuating the second mode of operation of the electromagnetic radiation assembly 10, as will be discussed below.
- an operator 30, when positioned in the operator's position 20, has a field of view which extends approximately 180 degrees from the operator's position towards the forward portion 12 of the vehicle. Further, and by using a pair of the assemblies 10, which are individually located at the positions 21 on the exterior portion of the overland vehicle 11 , the operator may, by looking along predetermined lines of sight, view areas beyond his normal field of view, and rearwardly of the operator's position 20.
- the operator 30 has a first line of sight 31 , which extends from the operator 30 to the assembly 10, which is located on the driver's side of the overland vehicle 11 , and which permits the operator to view rearwardly of the vehicle along the driver's side thereof.
- the operator 30 additionally has a second line of sight 32 which extends from the operator 30 to the passenger side of the overland vehicle and therefore permits the operator to view rearwardly along that side of the overland vehicle.
- the operator has a third line of sight which extends from the operator's position to the interior rearview mirror (not shown).
- the assembly 10 of the present invention in a first mode of operation, provides illumination zones 33 which extend rearwardly of the overland vehicle 11 and predominately out of the line of sight of the operator 30. These illumination zones have a predetermined beam spread 34 of approximately six meters when measured at a distance of about 8 meters from the assembly 10. Further, the deviation angle of the driver's side and passenger's side illumination zone may be varied based upon the geometry of the overland vehicle 11 upon which the assembly 10 is utilized.
- the assembly 10 In a first mode of operation 35, and when energized, the assembly 10 is operable to produce visibly discernible electromagnetic radiation which is provided to the illumination zones 33 in order to signal adjacent vehicles or other interested parties regarding the actions of the operator of the overland vehicle 11.
- the assembly 10 when energized, is operable to produce visibly discernable light which illuminates the side, and region adjacent the overland vehicle to aide, and assist an operator or passenger who may be entering, exiting, or working along the side of the overland vehicle 11.
- the assembly 10 of the present invention is incorporated into a mirror housing which is generally indicated by the numeral 40, and which is operable to be mounted at mirror locations 21 on the exterior surface of the overland vehicle 11.
- the mirror housing or enclosure has a rear wall 41 (Fig. 6), and a sidewall 42 which extends outwardly therefrom.
- the sidewall 42 has a peripheral edge 43 which defines an aperture 44 having given dimensions.
- the rear wall 41 , and sidewall 42 further defines a cavity 45 which is operable to receive and enclose the assembly 10 and other associated devices such as a bezel 46.
- the bezel may provide a cavity 47 which receives the assembly 10, and which further will movably support the assembly 10 within the housing 40.
- the assembly 10 can then be positionally adjusted, either manually, or remotely, as by a motorized actuator (not shown) to a given angular orientation relative to the first and second lines of sight 31 and 32 of the operator 30 of the overland vehicle 11. This provides a means by which the operator 30 may adjust his given field of view rearwardly of the overland vehicle 11.
- the assembly 10 of the present invention as shown in Fig.
- the semitransparent mirror 50 includes a semitransparent mirror which is generally indicated by the numeral 50, and which has a front or exterior facing surface 51 , and an opposite, or rearward facing surface 52.
- the semitransparent mirror further is defined by a peripheral edge 53, which substantially corresponds in shape and size to the aperture 44 which is defined by the peripheral edge 43 of the housing 40.
- the semitransparent mirror 50 substantially occludes the aperture 44.
- the semitransparent mirror 50 of the subject invention 10 may take on several forms. Referring now to Figs. 8 and 9, the semitransparent mirror 50 comprises, in a first form, a supporting, substantially transparent or translucent substrate 54, which has a forward facing surface 55, and an opposite rearward facing surface 56. A highly reflective mirror coating 60 is formed on the rearward facing surface 56.
- the mirror coating may be applied, in an alternative form, to the forward facing surface of the substrate 54.
- the discussion which follows, therefore, is applicable to mirrors where the mirror coating is applied to either the forward or rearward facing surfaces thereof.
- the highly reflective mirror coating 60 may comprise any number of different highly reflective, or mirror like coatings, or substances, such as chromium and the like, and which may be applied or formed in a manner which provides a commercially acceptable reflective surface.
- the resulting reflectance of the semitransparent mirror 50 should generally be, on average, greater than about 35%.
- the semitransparent mirror 50 has a first or primary region 61 and through which a visibly discernable electromagnetic radiation signal may pass; and an adjacent secondary region 62.
- the first or primary region 61 passes a portion of the visibly discernible electromagnetic radiation directed at same, while simultaneously reflecting a given percentage of the visibly discernible electromagnetic radiation which comes from the ambient environment.
- the secondary region is operable to reflect visibly discernible electromagnetic radiation, and is otherwise considered nominally opaque.
- the combined average reflectance of the overall surface area of the semitransparent mirror 50, including both the primary and secondary regions is normally greater than about 35% when employed for automotive applications. In other industrial applications, the average reflectance may be lower or higher depending upon the desired end use.
- the secondary region 62 is substantially continuous and reflects, for automotive applications, greater than about 35% of visible electromagnetic radiation and passes less than about 10% of visibly discernable electromagnetic radiation.
- the first or primary region 61 passes less than about 50% of visible electromagnetic radiation, and further reflects on average less than about 40% of visible electromagnetic radiation.
- the ranges noted above have been found suitable for automotive applications, however, it will be recognized that other broadened, or narrowed ranges may be useful for other industrial applications.
- the mirror coating 60 in the first or primary region 61 , of the semitransparent mirror 50 includes a plurality of discreet apertures 63, and which may be formed in a number of given patterns, and in various densities.
- the plurality of discreet apertures extend, in this form of the invention 10, through the mirror coating 60 to the rearward surface 56 of the transparent substrate 54.
- reduced thickness areas 64 may be formed in the mirror coating 60. These reduced thickness areas allow increased amounts of visibly discernable electromagnetic radiation to pass therethrough in relative comparison to the adjacent thicker areas in the secondary region 62. Therefore, the secondary region 62 has a first thickness dimension for the mirror coating 60 which is greater than the thickness dimension of the mirror coating 60 which defines the first or primary region 61. Still further, these two approaches may be combined, and wherein the apertures 63 be joined with a reduced thickness area 64. Referring now to Fig.
- a semitransparent mirror 50 is shown, and which is useful in the present invention 10.

- the dichroic mirror coatings 65 which are useful for such mirrors are also well known in the art, and further discussion regarding these dichroic mirror coatings is not warranted.
- a substantially opaque masking layer 66 is applied over the secondary region 62 thereby making the secondary region substantially opaque, and further permitting visible electromagnetic radiation to be passed through the first or primary region 61 which is unmasked.
- the dichroic mirror coating 65 may be selected to pass given bands of visibly discernable electromagnetic radiation in greater amounts than other bands of electromagnetic radiation thereby making the resulting semitransparent mirror 50, on average, an acceptable reflector of visibly discernable electromagnetic radiation, while simultaneously allowing increased amounts electromagnetic radiation of the selected band of electromagnetic radiation to pass therethrough.
- Fig. 11 a further form of an acceptable semitransparent mirror 50 which may be employed in the present invention 10 is seen in Fig. 11 , and which illustrates a prior art arrangement for a signaling assembly which incorporates an electrochromic mirror which is generally indicated by the numeral 70.

Still further, a multi-faceted reflector 120 is disposed in eccentric reflecting relation relative to the plurality of first and second electromagnetic radiation emitters 110 and 111 , respectively.
- the emitted electromagnetic radiation produced by the first electromagnetic radiation emitters is substantially reflected through the first region 61 in a first direction 134, by a first group of reflector facets 131
- the emitted electromagnetic radiation produced by the second electromagnetic radiation emitters 111 is substantially reflected by a second group of reflector facets 132 through the substrate region 61 , in a second direction 135.
- the visibly discernable electromagnetic radiation emitted by the first group of electromagnetic radiation emitters 110 travels generally, laterally, outwardly relative to the outside facing surface of the overland vehicle 11.
- the electromagnetic radiation emitted by the second group of light emitting diodes 111 travels laterally, downwardly or inwardly relative to the overland vehicle 11 , thereby aiding and assisting an operator 30 or passenger as the operator/passengers are entering or existing the vehicle, or further to assist in those situations, for example, when an operator or passenger may be working adjacent to the overland vehicle such as when replacing a flat tire or the like.
- the emitted electromagnetic radiation of the first and second light emitting diodes 110 and 111 may be of the same wavelength (and color), or may be of different wavelengths. Therefore, it will be seen that the electromagnetic radiation assembly 35 of the present invention provides many advantages over the prior art devices which have been utilized heretofore. As will be recognized, the present assembly 10 is compact, cost efficient, and further, provides a convenient means whereby visibly discernable electromagnetic radiation may be projected in various patterns relative to the overland vehicle to aid and assist the operator in the use of the overland vehicle.
