Discussion on Classification and Risk Assessment Method of Lighting in Fire Investigation
With the acceleration of urbanization,fire accidents have become increasingly frequent,especially those caused by lighting fixtures.Lighting fixtures are widely used in public and private areas,making their safety particularly important.Therefore,this study aims to conduct a classification research on lighting fixtures and explore corresponding fire hazard assessment methods,in order to reduce fire risks and ensure the safety of people's lives and property.Through comprehensive analysis of mainstream lighting fixtures in the market,the study categorizes lighting fixtures into incandescent lamps,fluorescent lamps,halogen lamps,LED lamps,and further divides them based on their heat generation characteristics,materials used,and circuit design differences.A fire risk assessment model based on the characteristics of lighting fixtures is constructed in this study.Various types of lighting fixtures are continuously tested in a laboratory simulated environment,with temperature changes recorded and potential fire ignition risks analyzed based on material ignition points.The results show that LED lamps have significantly lower fire risks compared with other types of lamps due to their lower operating temperatures and improved circuit designs.The effectiveness of the assessment model is further validated through actual case analysis.In response to the lack of standards,this study proposes a series of targeted safety standard formulations and improvement suggestions,including fire prevention requirements for lighting fixture materials,safety standards for circuit design,and the necessity of temperature monitoring mechanisms.The introduction of this assessment method provides a strong scientific basis for the formulation on safety standards of lighting fixtures and fire prevention and control,playing a guiding role in the development of relevant policies and the production safety of lighting fixtures.In conclusion,through scientific classification and risk assessment,the safety of lighting fixtures can be significantly improved,and fire accidents caused by lighting equipment also can be reduced.
