Summary:To provide a lamp which can suppress excessive brightness even if using a general light emitting semiconductor element such as a popular version.SOLUTION: A fan 21 of an LED lamp 10 is electrically connected to an LED element 11 in parallel therewith, and blows out air toward the LED element 11 at electricity-carrying. A cover part 18 is arranged so as to cover a light emitting part of the LED element 11 from the outside of a light emitting direction of the light emitting part, and has a light amount adjustment part 18a for making light from the light emitting part permeate itself in a state that the light amount emitted from the light emitting part is physically reduced. The LED elements 11 form one set by three pieces, and in its arrangement, two pieces of the LED elements 11 out of one set of the LED elements 11 are aligned in parallel along a vertical direction of the lamp. The remaining LED elements 11 are arranged so as to be aligned along left and right directions of the two pieces of LED elements 11. When setting a direction orthogonal to the vertical direction as a center axis, one set of the LED elements 11 are arranged so as to be symmetric in the vertical direction.SELECTED DRAWING: Figure 1 【課題】普及版などの一般的の発光半導体素子を用いた場合でも過度に明るくなることを抑制することができる灯具を提供する。【解決手段】ＬＥＤ灯具１０のファン２１はＬＥＤ素子１１に電気的に並列接続され、通電時にＬＥＤ素子１１に向けて送風する。カバー部１８は、ＬＥＤ素子１１の発光部をその発光方向外側から覆うように配置されており、発光部から発光される光量を物理的に減少させた状態で発光部の光を透過させる光量調整部１８ａを有して構成される。ＬＥＤ素子１１は３個で１組をなし、その配置は、１組のＬＥＤ素子１１のうち、２個のＬＥＤ素子１１を灯具の上下方向に沿って並設する。残りのＬＥＤ素子１１は、２個のＬＥＤ素子１１の左右方向に沿うように設ける。１組のＬＥＤ素子１１は、上下方向と直行する方向を中心軸としたとき、上下対称となるように配置する。【選択図】図１
