while the present invention is susceptible of embodiment in various forms , there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated . it should be further understood that the title of this section of this specification , namely , “ detailed description of the invention ”, relates to a requirement of the united states patent office , and does not imply , nor should be inferred to limit the subject matter disclosed herein . referring to fig1 , an illuminated novelty topper 10 is shown positioned on a pumpkin 12 carved as a jack - o - lantern 14 . it will be appreciated by those skilled in the art that while the topper 10 is shown positioned on a jack - o - lantern 14 , the topper 10 can be used with a wide variety of other vegetables and other objects that are hollow or can be hollowed out and which have a sufficiently thick skin on which the topper 10 can be positioned . in an embodiment , the topper 10 takes the form of a top hat 16 and includes a crown 18 and a brim 20 , and includes a depending skirt 22 . the crown 18 defines a housing 23 having an interior region 24 , and the brim 20 is formed at a juncture 26 of the crown 18 and the skirt 22 . the skirt 22 thus depends from the brim 20 opposite of the crown 18 . a lighting assembly or illumination module 28 is positioned in the hat interior region 24 , preferably within the crown 18 . in the illustrated embodiment , the lighting assembly 28 includes one or more lighting elements 30 , such as leds and a power source 32 . one such power source 32 is a battery . the illustrated topper 10 includes a photovoltaic cell 34 ( e . g ., a photocell or collector ), circuitry that can be provided on , for example , a circuit board 36 , and connectors 38 between the photocell 34 , the circuit board 36 , the battery 32 and the led 30 , as appropriate . in one contemplated embodiment , the photocell 34 is used to provide power to and to recharge the battery 32 , preferably . a rechargeable battery . circuitry 40 can be configured to illuminate the led 30 during the daytime , or it can be configured to recharge the battery 32 during the daytime and to illuminate the led 30 during the evening hours . those skilled in the art will recognize circuitry suitable to provide such nighttime illumination . a sensor 42 , which can be formed as part of or separate from the photocell 34 , can be used to sense the presence or absence of ambient light to illuminate the led 30 . in a present embodiment , the led 30 is mounted within the topper 10 at about the same height as the brim 20 . the skirt 22 , which depends from the brim 20 , depends a distance greater than that of the led 30 — that is , the led 30 is positioned within a recess 44 formed by the skirt 22 . in this manner , the led is protected from damage by the skirt . the skirt 22 is formed with a free edge 46 opposite the juncture 26 with the brim 20 . in a preferred embodiment , the free edge 46 has an undulating or serrated - like profile as indicated at 48 . it is contemplated that the undulating edge 48 can be used as a template or marker , to mark the location ( e . g ., score the skin ) on the pumpkin for cutting . it will be appreciated that using such a template or marker allows for making a cut in the pumpkin 12 such that the topper 10 has a close , snug fit in the pumpkin opening o , when placed on the jack - o - lantern 14 . this can prevent or reduce degradation of the pumpkin 12 flesh after it is cut , and may allow the jack - o - lantern 14 to have a longer useful life than it might otherwise . it is anticipated that the topper 10 will be manufactured from commonly available plastic or polymeric materials which can , if desired by colored or dyed , to provide a pleasing aesthetic effect . optionally , the topper 10 can include a protective cover 50 that is positioned over the led 30 when , for example , the topper 10 is used to mark out the pumpkin 12 . the cover 50 can be formed with any of a number of different mounting configurations , such as the illustrated bayonet mount 52 . alternately , the cover 50 can be formed from a material that is transparent or translucent ( e . g ., clear or light emitting ) so that the cover 50 can be left in place when the topper 10 is used to illuminate the jack - o - lantern 14 . alternate designs of hats 16 are shown in fig3 - 6 . the hat can take the shape of a bowler 116 as shown in fig3 , a ball cap 216 as shown in fig4 a and 4b , a conical pilgrim &# 39 ; s hat 316 as shown in fig5 , and a chefs hat ( or toque ) 416 as shown in fig6 . the location of the photocell 34 in the bowler 116 of fig3 can be similar to the photocell 34 location as illustrated in the ball cap 216 of fig4 a and 4b . it will also be appreciated that while the present topper 10 is shown and described as a hat 16 - 416 , other configurations , shapes or designs can be used that incorporate the novel feature of the present topper 10 . it will also be appreciated that although the topper is shown and described as used with a pumpkin , gourd or other like object , it can also be used with a wide variety of other objects , such as a snowman and the like , which other configurations , shapes or designs and uses are within the scope and spirit of the present disclosure . the present topper 10 provides a number of advantages over other , known ways in which a jack - o - lantern is made and illuminated . first , the use of a low power led greatly reduces any heat that an incandescent lamp or candle may subject the jack - o - lantern to . as such , there is little to no chance that a person can be burned . and there is considerably less heat to which the jack - o - lantern is subjected , thus less degradation . the present topper 10 can also light the jack - o - lantern automatically once dusk ( or night - time ) is sensed , thus precluding the need to remember to light a lamp or candle . the topper will remain illuminated even in winds that would otherwise blow out a candle . in addition , the edge 48 allows for closely marking the pumpkin 12 to better or more closely cut the pumpkin to fit the topper 10 . in that the skirt portion 22 depends from the brim 20 and is fitted into the pumpkin opening o , the topper will remain on the jack - o - lantern 14 once in position . all patents referred to herein , are hereby incorporated herein by reference , whether or not specifically done so within the text of this disclosure . in the present disclosure , the words “ a ” or “ an ” are to be taken to include both the singular and the plural . conversely , any reference to plural items shall , where appropriate , include the singular . from the foregoing it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present disclosure . it is to be understood that no limitation with respect to the specific embodiments illustrated is intended or should be inferred .
