It is flowed along X-direction in the space (that is, space equipped with radiating fin 440) that body 100 is surrounded, therefore cooling radiating fin
440 air themperature, it is low in the base end side (210 side of Light-emitting diode LED element) of cooling fin 430, in the front end of cooling fin 430
Side is got higher.That is, the Δ T (DEG C) in formula (3), becomes in the base end side (210 side of Light-emitting diode LED element) of cooling fin 430
Greatly, become smaller in the front end side of cooling fin 430.Therefore, in the present embodiment, due to the surface area B (m of cooling fin 4302) dissipating
The base end side (210 side of Light-emitting diode LED element) of backing 430 becomes smaller, becomes larger in the front end side of cooling fin 430, therefore is formed
For the heat flow Q2 of cooling fin 430 structures impartial in X-direction each position.That is, with radiating fin 440 along X-direction
The mode become larger is constituted.
In this way, in the present embodiment, being configured to:414b inclines relative to X-direction by specified angle below pedestal 410
Tiltedly, radiating fin 440 becomes larger along X-direction, also, is formed as the heat Q1 by pedestal 410 as a result, along X-axis
Direction is evenly dispersed, and the heat flow Q2 of cooling fin 430 is along the evenly dispersed structure of X-direction.
