Brief Introduction

Smart LED lights can significantly reduce usage costs for homes and businesses. It can be connected to a local area network and can communicate with smart phones or computers. People can use mobile phones or computers to remotely control the brightness and color of the bulbs, and even program the bulbs to achieve maximum energy saving.

Features of smart LED lights

High light energy conversion efficiency

Smart LED bulbs have higher light energy conversion efficiency than traditional incandescent lamps.… Read More

Photographic Requirements for Lighting

With the rapid progress of science and technology, the level of lighting technology has been further improved with the wide application of various electronic technologies. Especially in the field of film and television lighting, technological progress is more obvious. The rapid development of modern film and television technology has led to the rapid development of new image production, storage, transmission, and production equipment represented by digital technology systems.… Read More

LED driver in Brief

LED is a characteristic-sensitive semiconductor device and has negative temperature characteristics. Therefore, it needs to be stabilized and protected during the application process, resulting in the concept of driving. LED devices have almost harsh requirements for driving power. Unlike ordinary incandescent bulbs, LEDs can be directly connected to 220V AC mains.

Constant current drive of LED

The LED is driven by a low voltage of 2 to 3 volts.… Read More

The service life of LED lights and their advantages

The life of LED lights can reach more than 100,000 hours.

LED light-emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly emit red, yellow, blue, green, cyan, orange, purple, and white light.

 the characteristics of LED lights

1. High efficiency and energy saving

It only consumes a few kilowatts of electricity for one thousand hours.… Read More

What is LED Glare

Unsuitable brightness distribution in the field of view, or extreme brightness contrast in space or time, which causes visual discomfort and visual conditions that reduce the visibility of objects. Excessively high brightness or large brightness changes occur in a certain part of the field of view. Glare is one of the important causes of visual fatigue.

Glare is usually used to describe an environmental condition such as a bright sunny beach or a snow capped mountain.… Read More

Street lighting belongs to public lighting and is controlled by the government. Because LED has the characteristics of high efficiency, environmental protection, energy saving and long lifespan, LED light source can be the first to be applied in street and tunnel lighting.

Lamps used for road lighting are called street lamps. Road lighting fixtures that use LEDs as light sources are called LED street lights.… Read More

The Development History of Lighting

The earliest practical electric lamp was an incandescent lamp, but before the birth of the incandescent lamp, the British Humphrey David used a 2000 energy-saving dao cell and two carbon rods to make an arc lamp, but the brightness of this arc lamp was too strong. It generates too much heat and is not durable, and it cannot be used in general places.… Read More

The difference between LED grow lights and ordinary LED lights

1. Different wavelengths of light emission spectrum:

Plant growth lights are mainly red and blue components in the visible light du spectrum. Ordinary lights are just light-emitting diodes, and the spectrum is concentrated in the green part.

The LEDs used in the field of plant cultivation also exhibit the following characteristics: rich wavelength types, which coincide with the spectral range of plant photosynthesis and light morphology; the half-width of the spectral wave width is narrow, and the pure monochromatic light and compound spectrum can be combined as required; The light of a specific wavelength irradiates the crops in a balanced manner; it can not only regulate the flowering and fruiting of crops.… Read More

What is LED flood light

The LED flood light is a point light source that can illuminate evenly in all directions, and its illumination range can be adjusted arbitrarily. It is best to use it as an analogy to light bulbs and candles.

Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera range or inside an object.… Read More
