PROBLEM TO BE SOLVED: To provide an underwater fishing lamp capable of increasing gathering property and staying property of fish and improving catch quantity and angling rate by regularly and easily forming dark and light parts of light in depth direction and horizontal direction.SOLUTION: The underwater fishing lamp is provided with an end-side light source 2a, a center-side light source 2b, a lower end center light source 2c, and a lower end peripheral light source 2d. The end-side light source 2a and the center-side light source 2b are formed in a planar shape from a plurality of bullet-type LEDs 6a and surface mount LEDs 6b on substrates 4a, 4b respectively, the lower end center light source 2c is formed of a surface mount LED 6b placed nearly in the center of a substrate 4c, and the lower end peripheral light source 2d is formed in a planar shape from a plurality of bullet-type LEDs 6a placed around the lower end peripheral light source 2c. The directional angles of the bullet-type LED 6a and the surface mount LED 6b are 15-30° and 90-120°, respectively, and the bullet-type LEDs 6a forming the end-side light source 2a and the lower end peripheral light source 2d are arranged closer than the surface mount LEDs 6b forming the center-side light source 2b and the lower end center light source 2c.COPYRIGHT: (C)2012,JPO&INPIT【課題】水深方向や水平方向に対して光の濃淡部を規則的、かつ容易に形成し、魚類の蝟集性や滞留性を高めて漁獲量や釣果を向上させることが可能な水中集魚灯を提供する。【解決手段】端部側光源2a,中央側光源2bは、基板4a,4bに設置される複数の砲弾型LED6a及び表面実装型LED6bによってそれぞれ面状に形成され、下端中心光源2cは、基板4cの略中心に設置される表面実装型LED6bからなり、下端周囲光源2dは、下端中心光源2cの周囲に設置される複数の砲弾型LED6aによって面状に形成されており、砲弾型LED6a及び表面実装型LED6bの指向角度はそれぞれ15°~30°及び90°~120°であり、端部側光源2a及び下端周囲光源2dを形成する砲弾型LED6aは、中央側光源2b及び下端中心光源2cを形成する表面実装型LED6bよりも密に配置されている。【選択図】図1
