What materials are LED street light heat sinks made of?

During the LED lighting design process, engineers can start the specific LED lighting circuit design after selecting the LED driver solution. This circuit design process is not easy, and involves determining specific design requirements (such as voltage, current and number of LEDs, etc.), drawing application circuit d

1. LED structure and light-emitting principle 50 years ago, people already knew the basic knowledge that semiconductor materials can generate light, and the first commercial diode was produced in 1960. LED is the abbreviation of light emitting diode. Its basic structure is a piece of electroluminescent semicon

With the advent of high-power LEDs, LED life and power conversion efficiency have become the main considerations when designing LED lighting systems. In order to provide a constant current to maintain the consistency of LED color and brightness, a constant current LED driver can be used as a switching converter that pr

introduction To achieve better efficacy and color consistency, LED brightness is usually controlled by adjusting the duty cycle of the LED driver's PWM cycle. A PWM cycle can be divided into 2 control bits (2CONTROL BITS) clock cycles. In consumer electronics applications, the control bit resolution is usually

With the widespread use of high-power LEDs in lighting decoration and lighting, high - power LED drivers are becoming more and more important. It will become possible to use high-power LEDs for road lighting. Road lighting is the longest-lasting and most power-consuming light. The use of LEDs

1. What is LCD TV After waves of TV upgrades, people's attention has gradually shifted from computers to TVs. Now everyone is silently supporting low-carbon environmental protection work. Even if you take one less elevator at the subway station or walk one more staircase, it is also a manifestatio

  The price of LED bulbs continues to fall. A year ago, you could spend about $50 to buy a Philips 60W dimmable LED bulb to replace an old-fashioned bulb, but today, you can buy its home-brand 8W, 800-lumen Insignia bulb, which can replace a 60W incandescent bulb, for only $17 at Best Buy. What changes in the design o

1. Introduction Today, LED lighting is a mainstream technology. LED flashlights, traffic lights and car lights are everywhere, and countries are pushing to replace incandescent and fluorescent lamps in mains-powered residential, commercial and industrial applications with LED lights. The energy savings achieved
