E, empa leseli le fumanehang le arolelanoa pakeng tsa outputs. Phapang e entsoeng ka morero kapa tataiso e amanang le branches e tloaelehileng e hlokahala bakeng sa khanya e lekanyelitsoeng.

7. Na lihlooho tse ngata tsa LED li ka khanya pipe e le 'ngoe ea leseli?

E. Lihlooho tse ngata tsa LED li ka fa tataiso e le 'ngoe ho hlahisa leseli le ngata kapa mebala e 'maloa, empa libaka tsa tsona li lokela ho sitisa phapang e sa lekanang le mebala e bonahalang.

8. Na ho ka fokotseha bokhase ba leseli pakeng tsa li-pipe tse haufi le LED?

Sebelisa libarire tse se nang lebone, li-housings tse ntšo, sebaka se nepahetseng, le ho nepahala ha LED ho ea ho pipe ea leseli ho thibela leseli ho senyeha ho li-indicator tse haufi.

9. Ke thepa efe e betere bakeng sa pipe ea leseli ea LED: polycarbonate kapa acrylic?

E itšetlehile ka ts'ebeliso. Polycarbonate e matla le e hanyetsang mocheso, ha PMMA (acrylic) e fana ka ho hlaka ha optical le phepelo ea leseli e phahameng.
