    BACKGROUND OF THE INVENTION
  • Conventional lamp and lightings are designed with a fin-like structure to dissipate heat. If these lamp or lighting structure is employed as street lamp, birds build nest on these structure and the structure will also collect dust, and this will greatly reduce the heat dissipation efficiency. Further, these structures depend on convection current to dissipate heat which is less effective and the lamp or lightings are dirty after a period of time. Further, the additional fin-like structure or the lamp increases the cost of production and the fin-like structure may not suitable for all types of lamp or lightings.
  • Accordingly, it is the inventor's main objective to invent a lamp or lighting which mitigates the above drawbacks. The lamp structure has a larger surface area for heat dissipation and the cost of production is greatly reduced.
