LED ELEMENT FIXING DEVICE, COB SHEET COVER FOR LED ELEMENT FIXING DEVICE, REFLECTOR DEVICE AND LED LIGHT SOURCE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a technology for a novel LED light source module 1 in which a fixing part for an LED package 4 in respect to a COB fixing base 3 is made thin; a reflector 8 can be remarkably approached to the LED package 4; the number of component parts required for assembling the reflector 8 into a reflector fixing cylinder 7 can be substantially reduced; and an assembling efficiency for assembling the reflector 8 into the reflector fixing cylinder 7 can be increased further.SOLUTION: The LED light source module 1 of this invention comprises: an LED element fixing device 2 in which a COB sheet cover 5 is installed and fixed to the LED package 4 on the COB fixing base 3; and a reflector device 6 in which a spring receiving groove 73 and a stepped groove 74 are arranged continuously near an opening 70 of the reflector fixing cylinder 7, the reflector 8 is stored in the reflector fixing cylinder 7, a flange 83 is engaged with the stepped groove 74, a focal point opening 81 is restricted at a non-contact position of the LED package 4 and a spring ring 9 is fitted to the spring receiving groove 73.
