Abstract: The invention discloses a deformable high-power light fixture, which includes a light fixture body, a bracket assembly and other assemblies. The light fixture body includes a light source plate, a heat-dissipating body and a power supply box. The assemblies can be detachable from or sent externally away from the light fixture body. The bracket assembly can be detachable from the main light fixture body also, and it can rotate around its connection point with the light fixture body. The main light fixture body is provided with a glare shield. The present invention uses a common body to achieve various shape changes by splicing, which saves the investment of molds in the early stage and the cost of material preparation in the later stage, so that users can complete the assembly and replacement only by purchasing a single accessory. On the one hand, the glare shield can increase the reflectivity and reduce light loss.
