Problems solved by technology

[0004] However, in the endoscope device of Patent Document 1, the heat generated in the LED is discharged only through the conductor penetrating the substrate and the lead wire having a relatively small cross-sectional area connected to the conductor on the back side of the substrate, so it may not be possible to perform the heat sufficiently. cool down
In particular, in order to ensure a high light quantity, it is desirable to use LEDs driven with a large current, in which case the cooling problem may be more profound

Embodiment Construction

[0027] Next, an endoscope apparatus according to an embodiment of the present invention will be described with reference to the drawings.

[0028] Such as figure 1 with figure 2 As shown, the endoscope apparatus 1 of this embodiment has an insertion part 2 for inserting into a lumen of an endoscopic object. A cap-shaped adapter 3 covering the front end of the insertion portion 2 is attached.

[0029] Such as figure 1 with figure 2 As shown, the adapter 3 has: a metal mounting base 4 disposed at the front end of the insertion portion 2; a photographic optical system 5 fixed to the mounting base 4, an LED package 6, and a flexible substrate 7 (see figure 2 . ); a cover 9 having a glass plate 8 covering these components; and a mounting sleeve 10 integrally fixing the mounting base 4 and the cover 9 to the insertion portion 2 .

[0030] The mounting base 4 is provided with a through hole 11 for mounting the imaging optical system 5 , an LED fixing portion 12 for mounting ...

Abstract

The present invention provides an endoscope device. Even at a state that an LED driven by large current, the LED can be sufficiently cooled, and bright irradiation can be performed for an endoscopy object. The endoscope device comprises the following components: a metal mounting substrate (4) which is configured at a front end of an insertion part (2) and is provided with a projection (12) that projects to the front side; a flexible substrate (7) which is configured to a position except for the projection (12) on the mounting substrate (4) and is provided with an electrode pad (7b) at the surface side, while the back side is jointed with the mounting substrate (4) through thermal conductive jointing material (17); and an LED package (6) which is provided with electrodes (6c) that are welded on the electrode pads (7b) of the flexible substrate (7). Furthermore, the back part (6d) except for the electrodes (6c) on the LED package is jointed with a front surface of the projection (12) ofthe mounting substrate (4).

Description

technical field [0001] The present invention relates to endoscopic devices. Background technique [0002] Conventionally, as an endoscope device, a structure in which a substrate on which LEDs are mounted is fixed to the tip of an insertion portion is known. [0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 11-267099 [0004] However, in the endoscope device of Patent Document 1, the heat generated in the LED is discharged only through the conductor penetrating the substrate and the lead wire having a relatively small cross-sectional area connected to the conductor on the back side of the substrate, so it may not be possible to perform the heat sufficiently. cool down. In particular, in order to secure a higher light quantity, it is desirable to use LEDs driven with a large current, and in this case, the problem of cooling may be more profound. [0005] Therefore, an endoscope device that can sufficiently cool the LEDs and stably brightly illuminate a...
