研究目的
To evaluate the possibility of using halogen lamps, compact fluorescent lamps and LED lamps as direct substitutes of traditional 100 W incandescent lamps for selected residential lighting applications.
研究成果
The study concludes that not all substitutes declared as such by their manufacturers can replace traditional light bulbs in all cases. The type of the applied luminaire plays a decisive role in achieving equivalent lighting conditions. The results suggest that consumers should perform simplified screening tests at the workplace to ensure equivalent lighting conditions when replacing lamps.
研究不足
The tests were conducted with single items of the products which makes it impossible to evaluate individual lamps. Additionally, the study highlights that there is no one universal LED or compact fluorescent lamp in the market that works great with all luminaire designs.
1：Experimental Design and Method Selection:
The study involved examining a single halogen lamp, six compact fluorescent lamps, and six LED light sources as substitutes for a traditional 100 W incandescent lamp. All lamps operated in three luminaires. The basic evaluation criteria were illuminance, uniformity, and glare limitation at the workplace.
2：Sample Selection and Data Sources:
The examined lamps differed in the method of light generation, design solutions, and producers. A traditional 100 W incandescent lamp was also examined for comparison.
3：List of Experimental Equipment and Materials:
A KUKISUI AC power supply PCR 500 stabilized power supply unit was used for powering the light sources and luminaires. The measuring system included a luxmeter with a head capable of correction to V(λ) and a data recording system.
4：Experimental Procedures and Operational Workflow:
The measurement of lamps' luminous intensity distribution was performed with an extension arm photometer in C - planes. Photometric bodies of all lamps and selected lamps operating in the three luminaires were determined in a goniometer station.
5：Data Analysis Methods:
Lighting parameters calculations were done in Relux to evaluate the lighting equivalence of the selected sources of light.
