I made this dimmer circuit because I have a cheap chinese LED lamp that doesn’t have the option to dim its light. It is a simple PWM dimmer built with the well-knows 555 integrated circuit and a power ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

LED luminaires require precise power and heat management because LEDs convert most of the electrical energy they receive into heat rather than light. Without adequate thermal management, this heat can ...

The new driving force for the growth of white LED lighting is quite simple: lower energy consumption and much lower energy bills. By some calculations, the transition from traditional incandescent and ...

Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. An LED-driver reference design for an LED replacement ...

The deployment of electronic LED lighting has grown dramatically over the past five years. Most luminaire manufacturers now offer a family of high-bay industrial LED products operating at AC line ...

The HPL high-power lighting dielectric joins the Thermal Clad metal-core PCB line. Specifically formulated for high-power lighting LED applications, the 0.0015 in. dielectric withstands high ...
