OUTDOOR REFLECTING LAMP Filed Nov. 20, 1946 INVENTOR: STELLA J. H/RSHF/ELD B1 71 WcfM ATTORNEY Patented Oct. 11, 1949 UNlT ED "STATES PATENT OFFICE OUTDOOR REFLECTING Stella Hirshfield, New York, N. Y. Application November 20, 1946, Serial .No. 71Qy9 3 Claims.

My invention relates to lam s a d, m re a t cul rly, to lamps for theilluminat on of r gardens or other outdoor areas.

Objects of my inyentionare to provide for th illumination of a wide area around the lamp, to

illuminate this area by indirect or reflected light, to arrange reflecting surfaces or mirrors lover a light source in such a manner that the light reflected by these surfaces is spread over a wide circular area .of the floor or soil without any of the light rays being directed horizontally or upwardly, and to avoid, thereby, any substantial waste of light.

Other objects are to arrange the light source and the reflecting surfaces in such a manner that no direct light will be visible, and, thereby, to provide for a smooth or not blinding and comfortable illumination.

Further objects are to avoid excessive heat in the lightened area and excessive heat of the reflecting surfaces or reflectors and of other parts of the lamp, and to provide for ventilation of the reflectors and of the space between the light source and the reflectors.

Still another object is to provide for adjust-,

ment of the position of the reflecting surfaces whereby the light can be optionally spread very widely or condensed over a less wide :area.

As well known, outdoor lamps attract :bugs. These bugs, when recoiling from .the light source, annoy people in the lighted area. Still further objects are to avoid this nuisance, to provide a structure that does not allow an easy escape .of bugs from the heatof the light source after .they have approached the same whereby the space around the light source acts as a trap for bugs, and to provide for deposition of burned or dead bugs in a concealed recess of the lamp.

Still other objects are to obtain these results with handy and reliable means, and to provide a structure that can be inexpensively and quickly made, installed and maintained.

Still other objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims and from the accompanying drawing in which:

Fig. 1 shows a partly sectional side view of an illustrative embodiment of my invention, the cross-section of the sectionally represented parts being taken along the line ll in Fig. 2.

Fig. 2 shows a cross-section taken along the line 2-2 in Fig. 1 and seen from the bottom, a part of the reflector being broken off.

Referring to the drawing... numeral 3 indicates p wh n ma he e xsd t a pedestal 4 and may be either permanently secured to the floor .or soil or an outdoor place or temporarily posi- 5 tioned on a selectedspotof this floor or soil. The pp r a l oi the ea t se ies i ht source h i a upwardly i ted i ht emitting sur iace .6. Preferably, the l ght source 5 is constitu b we e e al earn bu h ua accessoriesnecessary for the operation f these bulbs may be arranged in any suitable .manner. F r mm hebe iwh w a d e 1 i e ed s d 9 the h st 3. a d a a e 8 t ig The r ay mprise more than one la er- 10? ifi m fil 119%? W10 Y l spaced layers l0 and II. Each of the layers 10 d A remedi s p uralit i parts. er s et av n le er reflectin 'swiaees an be ng epara e r m eac other b e rs o be n t s- These two layers are so shaped and positioned that the reflecting sectors 43 of the upper layer e tend o e th -ear ef l we aye 11 and eve ian with th reflectin e tors 13 of t lower layer. ?Ih gaps and the spa e b t n the layers provide for ample ventilation whereby ai h a e by the-li ht sou e-i5 wi l r d ly rise om the spa e betwe n the ght ciince and th reflector 9 and will escape quickly into the surroundin shape.-

h pa ts or the re l ctor :9 may h e nnected n any suit bl manner. rexample theseetors i the layer he pennant-ed by ar se .l: d a central disk I5, and the sectors of the layer H by a rim [6 and a central disk I1. Bolts or rods l8 may connect the two layers.

The reflector 9 may be supported in any suitable manner, preferably in a manner allowing adjustment of the distance between the reflector and the light source. For example, arms I9 have upper ends afiixed to the layer l l and lower ends afiixed to a sleeve surrounding the post 3. The sleeve 29 is slidable along the post 3 and can be secured at any desired height by a screw 2i.

The layers In and II extend substantially horizontally and may be plane or slightly curved. Preferably, they rise slightly from the center toward the circumference whereby the reflected light is spread over a wider area. But the inclination of the reflecting surfaces is sufliciently small to avoid any reflection in a horizontal or even upper side and a closed bottom. The upper edge 23 of the body 22 has a higher level than the surface 6 whereby only upwardly directed-light rays can pass from the surface 6 over the edge 23. Obviously, the mutual position of the surface 6 and of the edge 23 determin'esthe smallest angle' 24 between the horizontal direction and rays'projected from the light source toward the reflector 9 The, small angle 25 between the horizontal direction and the reflecting surface is so measured that all rays, including those rising under the angle 2e, are reflected downwardly. The geometrical condition for this effect is that the angle 25 is smaller than one half of the angle 24. The shown embodiment shows an angle 25 slightly smaller than this 'critical -measure whereby, for

example, a ray 26 is reflected in'the direction of the arrow 21 and the reflected light covers a very large area.

.The body 22 has the additional advantage to serve as a trap for bugs attracted by the light source 5. When these bugs are dazzled or partly burned by the heatof the surface 6, they will tumble against the heated inner surface of the body 22, will notescape into the open and will not have an opportunity for recovery. Instead, these bugs will remain in the body 22, will die and will fall into a recess 23 formed at the bottom of the body 22 betweenits wall and the outer wall of light source 5. v

I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways without departingfrom the spirit of my invention as it is obvious that the particular embodiment shown and described is only one of the many that may be'employed to attain the objects of my invention.- Y

Having described the nature of my invention, what I claim and desire to protect by Letters Patent is: r a 1. A lamp comprising a light source projecting light upwardly, a support for said light source, an inverted funnel-shaped holder body carried on said support and surrounding said light and having the top edge of said body extending above said light source, and a reflector positioned over said light source and having reflecting surfaces positioned at its lower side and rising toward the circumference of the reflector at an angle smaller than one half of the smallest angle between a line passing through the top edge of said funnel shaped holder body and the light rays projected onto the rising surfaces from .said light source and that do not pass through said funnel shaped body.

2. A lamp comprising a light source projecting light upwardly, a perforated reflector positioned 7 over said light source and having reflecting surfaces facing said light source, a second reflector positioned above said first reflector and having reflecting surfaces registering with the perforations insaid first reflector and being separated from said first reflector by gaps, each of said reflectors forming a part of avery flat cone pointing down toward the center of said light source.

3. A lamp comprising a support, a source of light carried on said support, an inverted funnel shaped hollow body carried on said support and surrounding said light and having the top edge of said body extending above said light source, supporting arms extending upwardly and outwardly from said support, a perforated reflector positioned on said arms at a point above said light source and said hollow body, said reflector being depressed slightly from its circumference to its center, the side of said reflector toward said light source having light reflecting surfaces, a second reflector positioned above said first reflector and spaced therefrom and having substantially the same contourof deflection as said first reflector, said second reflector having reflecting surfaces that register with the perforations in said first reflector, said reflectors being positioned suificiently above said hollow body that all light rays from said source not contacting said hollow body are reflected by said reflectors downwardly to be below a horizontal plane passing through the circumference of said first reflector.
