ABSTRACT:
A lighting device with a multiple cooling layer structure has at least one mounting heat conductive block, at least one light assembly and multiple heatsinks. The mounting heat conductive block has a front end, a rear end, a side and at least one shoulder. Each shoulder is formed at the side of the mounting bracket. The light assembly is mounted on the front end of the mounting bracket. Each heatsinks is mounted on one of the shoulders and the rear end of the mounting bracket. When the lighting device generates heat, the heat is able to drive away from the mounting bracket to the heatsinks. The lighting device is able to cool down. The mounting heat conductive block and the heat sinks are easy to manufacture and transfer heat more effectively.
