Solar LED Streetlight Housing Assembly

Create a simplified, solid CAD model of an integrated rectangular solar LED streetlight suitable for export as a STEP (.step) file. Overall dimensions: 26 inches long × 13.5 inches wide × 4 inches thick. These dimensions apply to the light housing only, excluding the mounting arm. Coordinate system: The length runs along the X-axis, the width along the Y-axis, and the thickness along the Z-axis. Center the housing at the origin. Main housing: Model a shallow rectangular enclosure with a flat rear surface and a recessed front lighting face. Use rounded corners approximately 0.5 inch in radius. Add a continuous raised perimeter rim approximately 0.5 inch wide around the front face. The long sides have narrow raised rails. Round or chamfer exposed edges to resemble a cast aluminum streetlight housing. Apply a black appearance. LED lighting face: Arrange 12 rectangular LED reflector modules in a centered grid of 3 columns across the width and 4 rows along the length. Reserve approximately 3 inches at one short end for a control compartment. Each module should measure approximately 5 inches along the housing length × 3.6 inches across its width, with approximately 0.3-inch gaps between modules. Each module has rounded corners and a shallow recessed reflector cavity with sloped sides. Add a central transverse divider that separates each reflector into two LED sections. Represent the LEDs with simple flat rectangular strips; omit individual LED chips and fine reflector textures. Control compartment: At the reserved short end, add a recessed rectangular area with a small centered rectangular sensor/control plate and two small circular indicator features. Include several small screw recesses around the compartment cover. Rear solar panel: On the opposite face, add a large, flat rectangular solar panel inset within a narrow perimeter frame. Represent the panel as one thin solid plate. Omit individual solar cells and wiring. Mounting connection: At the control-compartment end, add a centered cylindrical mounting socket projecting beyond the short edge, aligned with the housing length. Use an approximate outside diameter of 2.5 inches, inside diameter of 2 inches, and length of 3 inches. Add two reinforcing ribs connecting the socket to the housing. This socket is outside the stated housing dimensions. Model the housing, reflector modules, rear solar panel, and mounting socket as separate solid bodies in one assembly. Ensure all bodies are valid closed solids. Do not include the support pole, remote control, background, lettering, or decorative graphics.
