Abstract
PURPOSE: To improve a process precision to facilitate treatment by bury a part or the whole of a lead frame to form a basic stand dependent upon resin mold.
CONSTITUTION: Foot 30 of a lead frame is put into hole 10 of metallic mold 8, and resin 13 is injected from hole 11. A hemispherical protrusion is provided on concave 6 of mold 5 in the position corresponding to LED putting-on part 4, and a reflection mirror is provided around LED 20. This basic stand can be shaped with an error below 0.005 mm in outside dimensions by metallic molds 5 and 8. LED is put on 4, and lead pierce 3 and LED are connected in 21. Reflection frame 22 in resin has θ- shaped reflection window 23 and protrusion 24, and the inside of the window is made of mirror face. Protrusion 24 is inserted into hole 25 of basic stand 15 to fix the protrusion and the basic stand to each other. Colored diffusion film 25 is sticked to form 22 directly. When this basic stand is used, a dimension precision is good, and the number of constituent parts can be reduced to make work efficiency good.
