LED - Current Affairs Questions and Answers

1) LED lighting treatment can be a feasible alternative to HPS in greenhouse operations. What does HPS stand for?

a. High pressure solar lamps
b. High pressure sodium lamps
c. High powered sodium lamps
d. None of the above

Answer Explanation
ANSWER: High pressure sodium lamps Explanation: Supplemental light emitting diode lighting treatment can assist greenhouse tomato growers to reduce energy cost without impacting fruit quality attributes, as per new research. Findings indicate that energy savings LED could be an alternative to HPS or high pressure sodium lamps in greenhouse operations. LEDs have a potential for influencing phytochemical and labour profile of numerous high value crops.

2) Scientists have developed a new LED using which model?

a. Organic hybrid
b. Inorganic hybrid
c. Organic Inorganic hybrid
d. None of the above

Answer Explanation
ANSWER: Organic Inorganic hybrid Explanation: This LED uses organic-inorganic hybrid paving the way for cheaper and brighter lights and displays in the future. Materials called organometal halide perovskites have been used to build a highly functioning LED. Perovskites are any materials with the same type of crystal structure as calcium titanium oxide. Such brightness is due to the inherent high luminescent efficiency of this surface-treated, highly crystalline nanomaterial.
