How to Find the Right Lighting Solution for TV Broadcasting Sports Stadium

TLCI +CRI 90 + flicker free deliver the best possible illumination for eyes and cameras!

In some lighting occasions, especially in sports lighting projects, TLCI will always be mentioned. So what is TLCI?

TLCI means Television Lighting Consistency Index. This is an evaluation parameter created specifically for television broadcasting. We all understand the color rendering index CRI. TLCI and Ra are both an identification value for the true color restoration of an object. But they are different as well. RA is an identification value focuses on what the human eyes see and the color of the object itself. For large-scale broadcast events, cameras are needed to capture every shot. For camera capture, how to identify and restore the true color value, there is TLCI. The higher TLCI and CRI, the better the light quality and more real it is.

Besides of the CRI and TLCI, another crucial factor we also have to take into consideration, that is strobe. Strobe is the fluctuation of the luminous flux of an electric light source at a certain frequency. For example, if we take a photo of a lamp with the mobile phone, a streak distribution can often be founded, which is caused by stroboscopic light. The light source itself does not produce strobe, the presence or absence of strobe depends on the LED driver power supply. To determine whether a luminaire is flick free, we can first check what circuit is used for the driver. Usually, PFC+PWM circuit is no strobe. Higher power and efficiency can be achieved.

So can AGC product meet the standard? Of course the answer is yes.

• As long as we use the appropriate led chips for suitable sports lights, there is no problem to obtain TLCI≥90.

Take Nichia 3030 GRT-V3 as an example: When RA80, TLCI can reach 70; when RA90, TLCI is almost meet the standard up to 90.

LUMILEDS 5050:

It can be seen that RA90 led chips, at different colour temperatures, can achieve TLCI ≥ 90.

• Make sure the solution with driver Ripple factor<2%, and then no worry about flicker.
