Handle element for e.g. surgical-dental field, has base and cover with glass window directly or indirectly permitting passage of produced light by LED electronic chip, and contact elements providing power supply for LED electronic chip

摘要

#CMT# #/CMT# The element has an encapsulated LED module (10) whose LED electronic chip (60) is directly or indirectly fixed on a base (20). A cover (80) is fixed to the base to form tightly closed inner space (90) with the base, and the electronic chip is arranged in the inner space. The base and the cover have a glass window (84) for directly or indirectly permitting passage of produced light by the electronic chip. Contact elements (40, 50) provide power supply for the electronic chip, where the contact element (50) is a connecting wire. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a handle element. #CMT#USE : #/CMT# Used for a medical device such as dental medical device, in a surgical-dental field, dental field, orthopedics field, surgery such as bone surgery, orthopedics surgery, for eliminating dental calculus, for prophylactic applications for polishing tooth with brush or prophylactic cup, for preparing and measuring depth of channel of root, for intraosteal injection or for a laser device. #CMT#ADVANTAGE : #/CMT# The arrangement of the tightly closed inner space protect the LED electronic chip against influences of harmful environment, and avoiding the LED electronic chip itself to be negatively influenced by resin. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of an LED module of a handle. 10 : Encapsulated LED module 20 : Base 40, 50 : Contact elements 60 : LED electronic chip 80 : Cover 84 : Glass window 90 : Tightly closed inner space #CMT#METALLURGY : #/CMT# The contact element is made of gold and gold alloy, and is coved with a nickel layer. The cover and the base are made of a metallic material e.g. iron-nickel alloy.
