Abstract

The disclosure generally relates to generating lighting in an efficient way while in the outdoors. The designs are meant to maximize the amount of light generated, by the smallest assembly that is rugged to use in general outdoor activities and water sports. Further designs are related to hands-free mounting capabilities on outdoor equipment such as bikes, surfboards, snowboards and other similar equipment. Additional features include various filters, waterproofing, recharging or lighting differences which provide greater visual or photographic advantages to the user.

Claims (19)

1. A lighting apparatus comprising:

a plurality of light emitting members, encased in a durable housing; and

a diffuser and a condenser lens disposed over the plurality of light emitting members, wherein an area between the diffuser or condenser lens and the light emitting member defines a sealed cavity, and wherein the diffuser is disposed within a groove of an annular sidewall surrounding the sealed cavity;

wherein the durable housing provides waterproof protection to at least 20 feet below a water surface;

wherein the durable housing includes heat dissipation features;

wherein the lighting apparatus is less than 2 inches by 2 inches in size; and is in the general shape of a cube; and

wherein the lighting apparatus generates greater than 1000 lumens of light.

2. The lighting apparatus of claim 1 , further comprising a camera storage bracket.

3. A lighting apparatus for a photographic camera device, including a light emitting member; characterized in that, also included are a diffuser and a condenser lens; the light emitting member, the diffuser, and the condenser lens are provided in this order so that the light emitted from the light emitting member is irradiated to the outside through the diffuser and the condenser lens in this order;

wherein an area between a first surface of the diffuser and the light emitting member defines a first sealed cavity, wherein the diffuser has a second surface opposite to the first surface;

wherein the diffuser is disposed within a groove of an annular sidewall surrounding the first sealed cavity; and

wherein an area between the second surface of the diffuser and a planar surface of the condenser lens defines a second sealed cavity.

4. The lighting apparatus according to claim 3 , wherein the condenser lens is a Fresnel lens or a convex lens.

5. The lighting apparatus according to claim 3 , characterized in that, wherein the condenser lens is provided with an antireflection film on a side of the condenser lens facing the light emitting member, and/or, the condenser lens is provided with an antireflection film on a side of the condenser lens facing opposite to the light emitting member, the antireflection film is used to increase the intensity of transmitted light.

6. The lighting apparatus according to claim 3 , characterized in that, the condenser lens is a Fresnel lens, the lighting apparatus also includes a protective lens, said protective lens being fixedly disposed on a side of said Fresnel lens having a texture, an area between the protective lens and the Fresnel lens defining a third sealed cavity.

7. The lighting apparatus of claim 1 , wherein a light emitting member of the light emitting members comprise a light emitting diode (LED) light.

8. The lighting apparatus of claim 3 , wherein the lighting apparatus is in the general shape of a cube.

9. The lighting apparatus of claim 8 , wherein the durable housing provides waterproof protection to at least 20 feet below a water surface and the durable housing includes heat dissipation features.

10. The lighting apparatus of claim 9 , wherein the lighting apparatus is less than 2 inches by 2 inches in size.
