New, more efficient LED series from company Kingbright were recently introduced to you in our article Small but powerful LED series KP- 2012, where we presented you new stock types - red series SR-J4. Meanwhile we also enhanced our stock offer with green LED series (525nm) LED - ZGK as well as with yellow LED series - SYK. All these series have one feature in common - high efficiency, whch is praxis reflected in two aspects:
● significantly higher luminous flux than standard types (at the same current)
or
● significantly lower current necessary to reach the same brightness
For illustration we attach series of snapshots from the same device with two different green LEDs (various expositions at a common indoor lighting). In the left device, there´s a standard LED, in the right one the KP-3216ZGCK is used (compare only a green LED, red LEDs are the same). We believe, that these pictures say it all - the difference is really very big.
It´s necessary to mention, that because of a different technology of a chip, the operation (forward) voltage of the ZGK series is higher than at standard types, i.e. approx. 3.3V, 2V at a yellow series and and 2.2V at red series. As a value of brightness (cd) is dependent on a radiation angle, this value is at SMT types without optics always lower than for example at 5mm or 3mm THT LED. However, that doesn´t mean, that a given LED provides less amount of light - overall luminous flux of these types with the same chip is the same. The only difference is that LEDs with optics focus light into a narrower radiation angle.
Detailed information will provide you with the Kingbright SR-J4, ZGK, and SYK datasheets. Type „C“ at the marking of many LEDS - for example, ZGCK, SYCK means a transparent package (Clear).
