What ballasts are used for LEDs?
We don't use ballasts for LEDs. Ballasts are used with fluorescent lighting fixtures to both step up voltage to fire the tube and to provide an in-circuit load when the tube fires and conducts. LEDs have a series resistor either integral to the LED or separate to it which limits current in the LED when it is turned on.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
How much energy does a led use per hour?
LEDs come for different power ratings. Miniature LEDs use between approximately 40-90 mW. High-power LEDs - used for illumination - can use hundreds of watts per square centimeter.
Is there a light source can be used instead of laser in photoelectronics applications?
