T8 fluorescent lamps not only do not save energy and not environmentally friendly, and replaced the T8 lamps is T5 fluorescent lamps. It although satisfied energy save but include the mercury-cantaining not meet environmental protection requirements, it will ultimately be replaced by LED lamps. General LED Lamps are to make up by series-parallel and through the matte cover emitting light. The technology threshold is low and easy to copy. So must to faced with price competition in the market. We presents LED combined with side-light light guide bar to replace the T8 florescent. The different with general LED lamps are beautiful visual, low glare index, flame-proof, and light distribution can be designed. However side-light light guide bar has serious criticisms of the output efficiency, current efficiency was about 60% to 65%. We design structure on incident face to improve output efficiency, through the simulated and measured, we can increase output efficiency to 72%.
