THE FRONT ISOLATION BOLLING BY HIGH DEGREE OF EFFICIENCY LED LIGHTING FIXTURES

摘要

PURPOSE: A high efficiency LED lighting fixture is provided to improve the efficiency of a street lamp by applying the temperature in the front part to a reflection sheet and a diffusion sheet. CONSTITUTION: An LED light source(S3) and a board(S5) are combined to a package. A heat discharging plate(S7) is coated by using a heat cut-off agent(S6) beside a light source combined part. A heat cut-off film secludes the heat emitted from the side of the light source part by surrounding the side part of the light source. A heat shielding film shields the heat emitted from a heat discharging plate to the front part.
