Abstract
A panorama lamp with 360 degree peripheral illumination with reference to an axis of the lamp is disclosed. Each of the light units mounted on a heat sink has a light chip facing outward from the lamp. Either a protection cap or a circular wall lens can be optionally adopted to cap the top of the lamp. The protection cap provides protection to the chips of the lamp from being damaged. The circular wall lens modifies the beam profile of the lamp to meet various market requests.
