Seeing the situation in Russia and Ukraine makes people very worried.

Nowadays, more and more places install street lamps. Every country builds roads on a large scale to develop.

There are many kinds of energy waste, mainly natural resources waste such as electricity and water, and other aspects of squandering.

According to the report from Expert Market Research, the global LED panel light market size was around USD 17 billion in 2020. The market is further projected to grow at a CAGR of 14% over the forecast period of 2022-2027 to attain a value of USD 37.3 billion by 2026.

Firstly, gallium nitride (GAN) based epitaxial wafers are lining up on the substrate. This process is mainly completed in a metal-organic chemical vapor deposition epitaxial wafer furnace (MOCVD).

The LED chip is a solid-state semiconductor device. One end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply so that the whole chip is encapsulated by epoxy resin.

Luminous efficacy is a measure. It is how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt (lm/w) in the International System of Units (SI).

Have you found that now, no matter in the countryside or the city, as long as there is a road, street lamps will appear, bringing light to the night?

LED(Light-emitting diode) is a semiconductor device. 

Wikipedia interpreted as “A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. 

As the technology development. Do you want to save energy and money? Do you make more profits? Do you let LED lights will promote manufacturing productivity?
