LED candle flame light

Abstract

An LED candle flame light has a base member and an LED candle flame light filament component which extends upwardly therefrom. An inner transparent cover having the same outline shape of the filament is formfitted around the filament and encases it. An outer transparent cover encloses the inner cover. A heat sink member has an upper section and a lower section having a heat sink component fabricated of heat absorbent material. The heat sink component is configured to absorb heat generated by the filament. The component is threadably engaged to the base member such that it is adjacent to the base member, allowing it to absorb heat generated by the filament components. The outer covers can be of different shapes and are interchangeably attached to the base member.

DETAILED DESCRIPTION OF THE INVENTION

(7) LED candle flame light 1 of the present invention comprises base member 2 having top surface 4, opening 6 extending upward from bottom 8 of the base member towards the top surface. Sidewall 10 circumscribes opening 6. A first set of screw threads 16 extends from sidewall 6 and a second set of screw threads 18 extends from the sidewall. LED candle flame light filament 20 extends upwardly from top surface 4 of base member 2.

(8) Inner transparent cover 22 encloses filament 20. Cover 22 is attached to and extends upward from top surface 4 of base member 2. Advantageously, cover 22 has the same outline shape of filament 20 and is formfitted around the filament so as to closely encase it, as best seen in FIGS. 1-3. Currently filaments, especially in COB LED strip lighting, tend to flex, bend, and generally change into an undesired shape when illuminated. Cover 22 is specifically configured to ensure that filament 20 maintains its non-illuminated shape while the filament and its light 1 are illuminated.

(9) Outer transparent cover 24 encloses and encompasses inner cover 22. Outer cover 24 has bottom base 26 having screw threads 28. Screw threads 18 of base member 2 are configured to threadably engage screw threads 28 of bottom base 26 of outer cover 24. With regard to the connection of base member 2 and bottom base 26, screw threads 18 comprise a first connection means and screw threads 28 comprise a second connection means. It is contemplated that other means of connecting base member 2 of cover 22 and bottom base 26 of cover 24 can be utilized, such as by snap-on attachment tabs inserted into receiving slots.

(10) Heat sink member 30 comprises upper section 32 having screw threads 34 and lower section 36 comprising heat sink component 40 fabricated of heat absorbent material. Heat sink component 34 is configured to absorb heat generated by flame light filament 20. Screw threads 34 of heat sink member 40 threadably engage threads 16 of base member 2 such that upper section 32 of the heat sink member is located within opening 6 of the base member. Heat sink member 30 is then aligned adjacent to base member 2, as seen in FIG. 3.

(11) Outer transparent cover 24 of the present invention can take a variety of different shapes. Outer cover 24 is interchangeable with inner transparent cover 22 and its base member 2 by disengaging threads on bottom base 26 of the outer cover with those of threads 18 of the base member and screwing in the bottom base of another outer cover. For instance, outer cover 24 is globed shaped and is shown in FIGS. 3 and 5 as being threadably engaged by means of its screw threads 28 and threads 18 of base member 2. FIG. 6 is an example of outer cover 44 being egg shell shaped with its bottom base 46 threadably engaged with base member 2. It is contemplated that a variety of differently shaped transparent outer covers can be utilized with a single LED candle flame light inner cover and base member of the present invention. Regardless of the shape of the outer cover, each will provide a measure of protection for filament components 20 if the light is impacted; and will also be available as a safety feature when heat is generated during illumination of the light.

(12) However, heat sink member 30 is configured to absorb and dissipate most of the heat generated by filament 20, thus reducing the heat within inner cover 22. This permits flame 1 to function with higher wattages and thus greater illumination.

(13) Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
