1. Common points:

Both types of lighting are electrical systems that convert electrical energy into light energy, namely electrical lighting.

2, different points:

The light environment created by the two is very different, and the effects are quite different.

1) The lighting of the opening ceremony belongs to the stage lighting category, emphasizing the color change, brightness change, stroboscopic and other changes, so it needs dimming; and the venue lighting is to provide a stable light environment for sports competitions and audiences, de-icing dance, sports In addition to a few projects such as dance, the venue lighting requires a single color and uniform illumination.

2) Site lighting pursues uniform illumination, stable illumination, suitable light source display index and color temperature, and horizontal illumination and vertical illumination should be balanced, no glare, no stroboscopic; and stage lighting does not need these indicators.

3) The stage lighting installation capacity is large, but the use capacity is not necessarily large, the use capacity varies widely, and the capacity changes with the plot. The power consumption of the venue lighting is relatively fixed and cannot be changed at will, otherwise it will affect the normal performance of the game and the effect of the broadcast.

KNBL1-32 Residual Current Circuit Breaker With Over Load Protection

KNBL1-32 TWO FUNCTION : MCB AND RCCB FUNCTIONS

leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
