　　請參閱第１、２圖，所示者為本發明所提供之燈具散熱結構，其設於一用以設置發光體１１之基板１上，其中該基板１形成彎折狀，該發光體１１設於該基板１形成鈍角夾角之一側，俾供燈光斜向地朝兩側射出；而該基板１形成銳角夾角之一側設有一導熱體２，其中該導熱體２與該基板１是以鋁擠方式一體成形。該導熱體２為筒狀而呈中空，其兩端分別設有一封蓋２１，而該導熱體２之內壁環設有數個肋部２２，並以一內環壁２３連接各肋部２２，令各肋部２２之間分別形成散熱之通道２４。而該導熱體２之外周壁設有數個第一結合部２５，其中該第一結合部２５是由兩呈間隔設置之側板２５１構成，該二側板２５１之間形成有一安裝槽２５２，可供第一散熱結構３以一結合端３１１組設。其中該第一散熱結構３是由數個散熱板件３１組成，各散熱板件３１之一端緊密靠合而形成該結合端３１１，並嵌設於該安裝槽２５２中；而各散熱板件３１之另一端則形成為散熱端３１２，該散熱端３１２乃相對於該結合端３１１呈彎折狀，且呈放射狀地朝外伸出。如此，各散熱板件３１之間的間距則非為等距，換言之，越靠近該結合端３１１之處，其間距越小；相反地，越靠近該散熱端３１２則間距越大。藉此，該第一散熱結構３於靠近該散熱端３１２之處由於各散熱板件３１之間距變大，而具有更佳的通風效果，可更快地散逸熱量以達快速降溫的目的。Referring to Figures 1 and 2, the heat dissipation structure of the lamp provided by the present invention is provided on a substrate 1 for arranging the illuminant 11.

The first heat dissipation structure 3 is composed of a plurality of heat dissipation plate members 31.

The other end is formed as a heat dissipation end 312 which is bent relative to the joint end 311 and protrudes radially outward. Thus, the spacing between the heat dissipating plate members 31 is not equidistant, in other words, the closer to the bonding end 311, the smaller the pitch; conversely, the closer to the heat dissipating end 312, the larger the spacing. Thereby, the first heat dissipation structure 3 is closer to the heat dissipation end 312 because the distance between the heat dissipation plate members 31 becomes larger, and the ventilation effect is better, and the heat can be dissipated more quickly for the purpose of rapid temperature reduction.

The fixing screws 44 are disposed through the through holes 414 and fixed at both ends to integrally fix the heat dissipation plate members 41. The height of the spacer 43 is greater than the height of the protrusion 411, so that the heat dissipation plate members 41 are stacked on the spacer 43 to form a space 42 with each other for the airflow to flow into the space 42 for heat exchange. In addition, each of the convex portions 411 is respectively provided with a guiding hole 412. Each of the guiding holes 412 forms a communication duct of the space 42 of the heat radiating plate members 41, and the airflow flows between the heat radiating plate members 41 to improve the heat dissipation effect.
