Abrégé

A fishing lamp device capable of collecting fish such as cuttlefish over a wise range and catching fish efficiently, and a fishing method using it. The light source (10) of a fishing lamp device (100) is composed of three LED light sources (10a, 10b, 10c) respectively producing blue short wavelength light, green intermediate wavelength light and red long wavelength light. The LED light sources (10a, 10b, 10c) are set at respectively specified angles when fishing cuttlefish so that continuous irradiation regions are formed in the order of wavelengths -- a short-light-emission-wavelength LED light source (10a) lighting a sea surface region far from a fishing boat, an intermediate-light-emission-wavelength LED light source (10b) lighting a sea surface region contiguous to the first region, a long-light-emission-wavelength LED light source (10c) lighting a sea surface region close to the fishing boat. Accordingly, an effective irradiation range that provides a specified illuminance under sea forms incident regions that are deep in the intermediate region, and shallow in regions close to and far from the fishing boat as shown in curves A, B, c in Fig. 1.
