The present invention provides an illumination device having a curved reflector for use with a light-emitting device. The illumination device includes conical or funnel shaped lens having a top section, a bottom section, an outer surface and an inner surface. The bottom section is enlarged and contains a hollow interior formed by the lens inner surface to receive a curved reflector. The top section contains a cavity adaptable to receive a light-emitting device so that when the light is illuminated, light is transmitted through the reflector lens. As light travels towards the bottom section, the curved reflector deflects light in the horizontal direction through the lens to prevent light from being absorbed by the base. The reflector lens outer and inner surfaces contain ridges to form a grid-like pattern to disperse light. This configuration provides an efficient means to transmit light to illuminate a surrounding area.

DETAILED DESCRIPTION The present invention relates to a reflector device for use with a lantern.
The reflector includes a cone-like or funnel-shaped lens having a top section to receive a light emitting device and a bottom section to receive a curved reflector.
The lens and reflector are supported and held together by a base structure.
The light-emitting device emits light into and through the lens thickness.
Light propagates through the lens and is diffused to illuminate surrounding areas.
The inner and outer surfaces of the reflector contain ridges to form surface irregularities to evenly disperse the light as it passes through the lens.
The lens bottom section includes a hollow interior configured to receive a curved/parabolic shaped cone-like reflector.
By inserting the curved reflector in the lens bottom section, light that would ordinarily be absorbed by the base portion can be deflected outward from the lantern to illuminate surrounding areas.
This configuration provides an efficient way to reflect and use the emitted light that would ordinarily be absorbed by the base structure.
The reflector device can be mounted on a lantern, lamp or any other device where it is desired to reflect light.
The lens is fabricated from a transparent or translucent glass or plastic material capable of transmitting light.
The curved reflector is most preferably fabricated from a highly reflective metallic material or a plastic plated with a reflective surface.
