Reduce the Cost of LED Lights

LED chips occupy a major part of the cost of LED lamps, so the main way to reduce the cost of LEDs is to reduce the cost of LED chips.

The key to the development of LED chip technology lies in the base material and epitaxial growth technology. The substrate materials have been developed from traditional sapphire materials, silicon and silicon carbide to new materials such as zinc oxide and gallium nitride.… Read More

1. Overview

In the field of traditional lighting, the concept and definition of lamps and luminaires are clear. Lamps and fixtures have their own applicable product standards, supporting technical standards and application standards to regulate their product quality and safe use, which well solves the matching and replacement of lamps and fixtures. Lamps from any manufacturer can be interchanged with fixtures from any manufacturer as long as they meet the relevant standards.… Read More

Classification of lighting methods

According to the spatial distribution of the luminous flux of the lamps and the installation methods of the lamps, indoor lighting methods can be divided into five types.

1. Direct lighting

The light is emitted through the luminaire, and 90%-100% of the luminous flux reaches the assumed work surface. This lighting method is direct lighting. This lighting method has a strong contrast between light and dark, and can create interesting and vivid light and shadow effects, which can highlight the dominance of the work surface in the whole environment.… Read More

1. Foreword

With the rapid development of information technology and the continuous progress of society, the popularization of high-power LED lighting applications, people’s requirements for efficient control and functional diversification of LED lighting are also increasing, and LED intelligent lighting systems have emerged as the times require. The LED intelligent lighting system makes full use of electronic technology, communication technology and computer network technology to organically connect various LED lighting fixtures in the building to achieve effective management and control.… Read More

Brief Introduction

Power factor is never an issue. In the past, countries all over the world had regulations, requiring power exceeding 75 watts to have a power factor requirement. Therefore, there has never been any power factor requirement for lamps. Just like fluorescent lamps, the power factor is very poor, and no one has ever raised an opinion.

Later, there were energy-saving lamps, although the state put forward a requirement, but it was very loose, and there were only requirements for more than 15 watts.… Read More
