LED EMITTER WITH VOLTAGE CONTROL LEAD

摘要

PROBLEM TO BE SOLVED: To provide an LED emitter mounted on a metal base board in which significant lowering of luminance is prevented even after long time continuous use by protecting the LED against the heat of a voltage control element. SOLUTION: A purality of LED chips are mounted on a metal base board 2 wherein each chip is applied with a corresponding lens mold 10 thus constituting an LED emitter 1. Leads 4 for supplying the LED chips with a driving voltage are connected with a circuit pattern on the board 2 and a module 3 of voltage control circuit is inserted in the way of the lead 4. Since a voltage control element generating heat is not mounted on the board, the LED chip is insuspectible to the heat and significant lowering of luminance is prevented even after continuous use.
