Nowadays, the world is running behind power generation as well as power saving. In the lighting industry, the L.E.D. bulb is used for lighting purposes. The main problem faced by the world is heat dissipation from a heat sink by active or passive cooling. The system accessories enhance the overall cost by using active cooling. This paper studied that it has been used to reduce the overall cost of L.E.D. bulbs by increasing the heat transfer rate concerning increasing heat transfer coefficient. It needs to understand the various parameters such as porosity, heat transfer rate, laminar flow, density, and heat transfer modes to achieve the above-desired result. Their application is for street lights, gardens, mall parking, and bulging decorative lights. The cross-shape fin array is a suitable replacement with porosity of more than 0.85 for a proper swirl during the cooling time for an active cooling system for an existing bulb.
