The heat dissipation model of the bionic illuminating lamp is shown in figure 3.
The heat generated during operation of the LED light source is eventually transferred in convection/radiation by multi-stage conductive heat dissipation. The expression for heat transfer is as follows:

The method for solving the convective heat transfer coefficient h comprises the following steps:
Nu＝CRenPrm (2)
in the formulae (2) and (3)
Nu; C. n and m are obtained by experiments, and the experimental values are taken; re is Reynolds number, and Re is ul/mu; pr is the prandtl number, and Pr is mu Cp/lambda; λ is the coefficient of thermal conductivity; l is a characteristic length; u is the fluid velocity, m 3/s; mu is the kinetic viscosity coefficient.
