What is trailing edge leading edge?

Leading-edge: inductive loads (e.g. magnetic low voltage transformers), resistive loads (e.g. incandescent). Trailing-edge: capacitive loads (e.g. electronic low voltage transformers, LED drivers), resistive loads (e.g. incandescent).

Is my dimmer leading or trailing edge?

These more modern dimmers have many benefits over the leading edge type. These improvements include smoother dimming with less buzzing and interference. Trailing edge dimmers have a much lower minimum load than the leading edge, making them far more suitable for powering LEDs.

What does trailing edge dimmable mean?

Trailing Edge Dimming (electronic dimming) utilizes a current that is turned off as the AC waveform ends, right before it crosses zero. This type of dimming is typically used with electronic drivers, and does not result in a rush of voltage (and in turn, a rush of current) to the light source.

What is leading edge compatible?

Leading edge dimmers are suitable for inductive load, for example magnetic low voltage transformers; and resistive loads like incandescent light bulbs. Trailing edge dimmers are suitable for capacitive loads like electric low voltage transformers and LED drivers as well as resistive loads like incandescent bulbs.

What is the definition of trailing edge?

: the rearmost edge of an object that moves and especially of an airfoil.

Is triac dimming leading edge?

All TRIAC (Triode for Alternating Current) based dimmers are leading edge dimmers. Flickering in LED lamps may occur due to the fact these devices are generally driven by LED drivers utilizing regulated power supplies that supply regulated current and voltage to the LED lamps from AC utility lines.

What is the purpose of trailing edge?

The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft.

What is the shape of the airfoil at the leading edge?

Explanation: The shape of the airfoil at the leading edge is usually circular with a leading edge radius of approximately 0.02c.

Is TRIAC dimming forward or reverse phase?

Forward Phase (Leading Edge) Controls The most common technology used to produce forward phase controls is Triac based dimming. In this type of dimming, a semiconductor acts as a switch, controlling both positive and negative half cycles.

Is TRIAC dimming the same as ELV?

Some common dimming technologies include Forward Phase, Reverse Phase (ELV), and 0-10V. Forward Phase: Forward phase-cut dimming (commonly referred to as incandescent or Triac dimming) is the most common dimming method. ELV dimmers are generally very compatible with LED loads, offering smoother dimming to low levels.

What would happen when the trailing edge flaps are lowered?

Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift. In addition, the large aft-projected area of the flap increases the drag of the aircraft. This helps the airplane slow down for landing.
