< Topic >There is no problem, degradation with the ultraviolet ray of breaking, breaking and the resin make housing of the circuit by the rainfall and watering due to the radiant heat of internal power source, being long-lived, nonuniformity of the lighting field is little, the light bulb die LED illuminating for flora and fauna rearing is offered.SolutionsPutting the illuminant and the aforementioned LED illuminant which lay out the multiple LED illuminants on the substrate of square, to the aforementioned substrate being the flat die LED illuminating which does not provide the power supply section inside individual the clear cover board and the aforementioned illuminant and the aforementioned clear cover board which are provided on opposite side install and consist of with the possible housing and the side board, it offers those which possess the form which becomes the end extent facing toward the illuminant where cross section of the housing which consists of the metallic materials lays out the multiple LED illuminants on the substrate of aforementioned square.< Choice figure >Figure 4A【課題】内蔵電源の輻射熱による破壊、降雨や散水による回路の破壊、樹脂製ハウジングの紫外線による劣化という問題がない、長寿命で、照射領域のムラが少ない、動植物育成用電球型LED照明装置を提供する。【解決手段】方形の基板上に複数のLED光源を配置した光源部と、前記LED光源を挟んで前記基板と反対側に設けられたクリアカバー板と、前記光源部及び前記クリアカバー板が取り付け可能なハウジングと、側板とからなる個別の内部電源部を設けない平板型LED照明装置であって、金属材料からなるハウジングの断面形状が前記方形の基板上に複数のLED光源を配置した光源部に向かって末広がりとなる形状を有するものを提供する。【選択図】図4A
