Abstract [sv]

Syfte: Syftet med denna studie var att jämföra läshastigheten mellan en allmänt tillgänglig halogen-lampa och en allmänt tillgänglig LED-lampa.

 

Metod: I studien gjordes kliniska förtester och om deltagarna hade tillräckligt god syn för att läsa det lästest som användes så fick de läsa testet under två olika lampor, en halogen och en LED. I studien deltog 30 personer, 5 män och 25 kvinnor i åldrarna 21-59 år med en medelålder på 26 år. Hur många ord deltagarna läste per minut antecknades och sedan jämfördes läshastigheten mellan de två lamporna. Deltagarna fick även avgöra subjektivt vilken lampa som de föredrog att läsa i. För att analysera reslutaten användes Excel för att utföra ett parat T-test.

 

Resultat: Läshastigheten mellan de två olika lamporna som användes i studien var lika (p=0.18), medelvärdet av ord lästa/minut under halogen var 174 och medelvärdet av ord lästa/minut under LED var 176. 36,7 % av deltagarna föredrog att läsa under LED-lampan, 26,7 % föredrog att läsa under Halogen-lampan och resterande 36,7% angav ingen subjektiv skillnad mellan lamporna.

 

Slutsats: De lampor som användes i denna studie gav ingen skillnad i läshastighet hos de olika individer som deltog.

Abstract [en]

The aim of this study was to compare reading speed between a halogen- and a LED-lamp.

 

The study consisted of different tests to see if the participants had visual acuity enough to perform the readingtest used in the study. If the participant had visual acuity enough they were asked to perform the test under two different lamps, one halogen-lamp and one LED-lamp. There were 30 participants in this study, 5 men and 25 women in the age between 21-59 with a mean age of 26 years. The number of words the participants read under each lamp was noted in a protocol and from this protocol the reading speed was compared statistically between the two lamps. The participants did not know which lamp that was tested first or last and was also asked wich lamp they preffered. Excel was used to analyse the data and a paired t-test was done.

 

The reading speed for both lamps used in this study was the same (p=0.18), the mean of words read per minute under the halogen-lamp was 174 and the mean of words read per minute under the LED-lamp was 176. 26,7 % preffered reading under the halogen-lamp, 36,7 % preferred reading under the LED-lamp and 36,7 % did not give any subjective difference between the lamps.

 

Overall this study shows no difference in reading speed between the halogen- and LED-lamp tested on the participants in this study.
