Headlamp integrated into a flexible composite headband
This disclosure provides a portable lamp worn on the head and method of construction for the portable lamp. The construction method forms a composite structure that improves the comfort, reduces the volume, and better distributes the weight of the components of the lamp. The method of construction allows for a flexible material or set of flexible materials to be used to encapsulate the rigid parts of the headlamp. The flexible and rigid materials can be joined together in a heat press process that results in a single composite structure that has both attributes of the rigid material(s) and the flexible material(s) in different areas of the lamp. The battery can be located at the back or otherwise remote from the light to improve weight distribution and comfort for the user.
1. A wearable electric light with a composite structure comprising:
a first flexible support member;
a second flexible support member;
a rigid housing at least partially sandwiched between the first and second flexible support members, wherein the first and second flexible support members are adhered to the rigid housing and wherein the first and second flexible support members extend beyond the rigid housing and are adhered to each other, so that the rigid outer housing is substantially encapsulated between the first and second flexible support members, forming a composite structure with multiple layers of flexible support members, and with rigid and flexible regions, wherein each of the first flexible support member and the second flexible support member extend beyond the rigid housing in a band; and
an electrical light source housed within the rigid housing, the electrical light source having at least one optical lens.
2. The wearable electric light of claim 1 , wherein the first and second flexible support members are made from a flexible polymer, textile or other fabric material.
3. The wearable electric light of claim 2 , wherein the flexible material is impregnated or coated with an adhesive, wherein the layers of flexible support members are joined to each other by application of heat and/or pressure to form the composite structure with the first flexible support member forming an outer layer adapted to face away from a user, and the second flexible support member forming an inner layer adapted to rest against the user, with the rigid housing at least partially sandwiched between the first and second flexible support members.
4. The wearable electric light of claim 1 , wherein the rigid housing has a foundation, and a frame, and defines a cavity formed by the foundation and the frame, the frame defining the sides of the cavity and the foundation defining the back of the cavity, so that the cavity is defined in five directions and is open in the sixth direction, and wherein the first and second flexible support members are adhered to the foundation and sides of the frame, and to each other, and wherein the support members do not fully cover the cavity.
5. The wearable electric light of claim 4 , further comprising a brim around a perimeter of the rigid housing, wherein the first flexible support member is adhered to the front of the brim and to the second flexible support member, and wherein the second flexible support member is adhered to the foundation, the back of the brim, and to the first flexible support member, so that the brim is sandwiched between the first flexible support member and the second flexible support member.
6. The wearable electric light of claim 1 , further comprising a layer of resilient material between the rigid housing and the first and second flexible support members.
7. The wearable electric light of claim 1 , wherein at least one of the first flexible support member and the second flexible support member extend beyond the rigid housing in a band.
8. The wearable electric light of claim 7 , wherein a battery is supported by the band remote from the rigid housing, wherein a power cord connecting the battery to the electric light source is at least partially held between the first flexible support member and the second flexible support member.
9. The wearable electric light of claim 1 , wherein the first and second flexible support members extend beyond the rigid housing and are adhered to each other to form a seal that encircles the rigid housing.
10. The wearable electric light of claim 1 , wherein the first flexible support member forms an outer layer adapted to face away from a user, and the second flexible support member forms an inner layer adapted to rest against the user, and wherein the second flexible member covers the back of the rigid housing and is adapted to prevent the rigid housing from contacting the user.
11. A method of constructing a wearable electric light with a composite structure, the method comprising:
placing a rigid housing defining a cavity between a first layer of flexible material and a second layer of flexible material, each of the first layer of flexible material and second layer of flexible material having wings that extend outwards beyond the rigid material; and
compressing the first layer of flexible material and the second layer of flexible material together so that the first layer of flexible material is adhered to the rigid housing and to the second layer of flexible material, and the second layer of flexible material is adhered to the rigid housing and to the first layer of flexible material, with the rigid housing at least partially sandwiched between the first layer of flexible material and the second layer of flexible material to form a composite structure with multiple layers, and with the rigid outer housing substantially encapsulated between the first flexible support member layer and the second flexible support member layer.
12. The method of claim 11 , further comprising creating a hole in the first layer, and aligning the hole and the cavity so that the first layer of flexible material does not cover the cavity.
13. The method of claim 11 , further comprising inserting a lighting system having at least one light source and at least one lens into the cavity.
14. A wearable electric light with a composite structure comprising:
a first flexible support member;
a second flexible support member;
a rigid housing at least partially sandwiched between the first and second flexible support members, wherein the first and second flexible support members are adhered to the rigid housing and wherein the first and second flexible support members extend beyond the rigid housing and are adhered to each other, so that the rigid outer housing is substantially encapsulated between the first and second flexible support members, forming a composite structure with multiple layers of flexible support members, and with rigid and flexible regions, wherein each of the first flexible support member and the second flexible support member extend beyond the rigid housing in a band and the first flexible support member and the second flexible support member sandwich two respective ends of a strap; and
an electrical light source housed within the rigid housing, the electrical light source having at least one optical lens.
