In some implementations, the method includes mounting at least one LED module on a top portion of a first substrate for providing light. A lens portion is mounted on a second substrate in a first region of the second substrate. The lens portion illuminates the light from the at least one LED module and the second substrate comprises the first region having a first diameter and a second region for providing a path for the illuminating light having a second diameter. The first diameter is greater than the second diameter. The second substrate is mounted on the first substrate. A substance is applied to a top portion of the second substrate from an end of the first diameter to the end of the second diameter and to a side portion of the second substrate in the second region. ## Claims ### Claim 1 A method of manufacturing a flash module comprising: mounting at least one LED module on a top portion of a first substrate for providing light; mounting a lens portion on a second substrate under a first region of the second substrate, wherein the lens portion illuminates the light from the at least one LED module and the second substrate comprises the first region having a first diameter and a second region for providing a path for the illuminating light having a second diameter, wherein the first diameter is greater than the second diameter and the second region is on top of the first region; and mounting the second substrate on the first substrate; ### Claim 2 (depends on 1) The method of claim 1, wherein: the flash module comprises the first substrate and the second substrate; and a shape of a side-view of the flash module is a top hat shape. ### Claim 3 (depends on 1) The method of claim 1, wherein: the lens portion is attached to the first region of the second substrate;
