Title:
LIGHTING DEVICE AND DISPLAY DEVICE USING SAME
Document Type and Number:
Japanese Patent JP3931127
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain lighting which can suppress influence of heat generated by a light emitting body and has high light use efficiency and small light quantity variation.
SOLUTION: An LED chip 10 and a tapered rod 20 are held by an LED base 30, an LED substrate 31, an LED holder 32, a collar 33, a spacer 34, a fixing screw 35, and a rod holder 36 in one body at a specified position where incidence ends of the LED chip 10 and tapered rod 20 are close to each other across a thin air layer. In this case, the LED chip 10 is held by the LED base 30 which functions as a heat conduction part and the LED holder 32 which functions as a heat conduction part through the LED substrate 31. Further, the LED holder 32 is provided with a heat radiation fin 32A as a heat radiation part for radiating the heat generated by the LED chip 10 on the opposite side from the surface where the LED chip 10 is held.
