LED Tutorial This is a general tutorial for users of TracePro LC, TracePro and TracePro Expert. LED TutorialCreate an LED package based on manufacturer’s data sheet. This example will build a source model for a Siemens LWT676 surface mount LED based on the Manufacturer’s data sheet. The dimensions will be used to build a solid model and the source output will be defined to match the LED photometric curve.TracePro Release 3.2 2 LED TutorialTracePro User Interface The figure shows a solid block in TracePro. The following user interface items will be used in this example Model Window System Tree Zoom All Polar Candela DistributionView XY View YZ Select SurfaceDefine MenuInsert Menu Analysis Menu3 TracePro Release 3.2 LED TutorialCreate a Thin Sheet First analyze the package to determine the best method of constructing the geometry in TracePro. The symmetry of the package suggests starting from a Thin Sheet and extrude the top and bottom halves with a small draft angle. Construct Thin Sheet in the XY plane. 1. Start TracePro and open a new model with File|New. 2. Select View|Profiles|XY or click the View XY button on the toolbar 3. Open the Insert|Primative Solid dialog and select the Thin Sheet tab. 4. Enter the four corners of the Thin Sheet in mm in the dialog box and click the Insert Button. 5. Press the Zoom All button or select the View|Zoom|All menu to see the new object .TracePro Release 3.2 4 LED TutorialSelecting a Surface TracePro uses surface and object selections for many operations. 1. Close the Insert Primitive Solid dialog box. The thin sheet object has only one surface 2. Select View|Profiles|YZ or click the View YZ button on the toolbar to view the profile of the Thin Sheet. 3. Select the surface using the Edit|Select|Surface menu (or Select Surface tool), use the mouse to “pick” the rod end. You may want to use the system tree by opening the system tree with Window|Split and selecting the surface.5 TracePro Release 3.2 LED TutorialUse Sweep to form
