In, a portion heat passed to the relatively low lamp body and lens of temperature by closing free convection in lamp chamber before this, then
Exchanged heat again by lamp body and lens with extraneous air；Another part heat is then transmitted to heat radiator fin by heat transfer, by
Fin exchanges heat with outside air.Comparatively speaking, the heat exchange efficiency of front portion is low, and heat is mainly consumed by second of approach
Dissipate.
Luminous flux detection is carried out under 25 DEG C of environment, according to LED luminous flux and the relation of temperature, now Tc can be extrapolated
=72 DEG C.In this case, it is 1100lm that can calculate luminous flux.
To sum up result illustrates that the system all has good performance in terms of radiating, service life and optical efficiency.
