The floodlight is a point light source that can illuminate evenly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Floodlights are the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene, and multiple floodlights can be used in the scene to produce better results.… Read More
Gas station usually refers to a service station that retails gasoline and motor oil for automobiles and other motor vehicles, and is generally a place where fuel and lubricants are added.
As gas stations are inflammable and explosive places, installing LED explosion-proof lights in gas stations is an indispensable part of a safe environment.… Read More
Some EL lamp users specify the brightness output they need, but they don’t seem to all use the same unit. How to convert between cd/m2 (candlelight/square meter), lux and FL (foot-lamberts)?
How did the LED lighting rebate policy come about? Why did the country formulate financial rebates related to energy-saving lamps and LED lighting? Because with the rapid development of the world economy, environmental and energy issues slowly surfaced and became the topic and center of global discussion. Become an important factor restricting economic development.… Read More
Explosion-hazardous places refer to places where flammable and explosive substances are produced, used, and stored, and explosive mixtures can be formed, and there is a danger of explosion. Fire hazard sites refer to the production, use, processing, storage, or transportation of flammable liquids with a flash point higher than the ambient temperature of the site, or combustible dust, combustible fibers, or solid combustible substances, and in the production process.… Read More

Light is one of the important conditions necessary for plant growth and development. After long-term measurement, observation and research, the law of spectral components required by different types of plants in the growth and development process varies with space. Shortwave light decreases with the increase in dimensionality. Increase and increase. The law of change with time is that the long-wave light increases in winter, and the short-wave light increases in summer.… Read More
The LED light source is a piece of electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wire, and is sealed with epoxy resin to protect the inner core wire. Function, finally install the shell, so the seismic performance of the LED lamp is very good.… Read More
When we manufacture LED lights, there are many indicators that need to be gradually improved, such as life span, EMC, environmental protection, safety, reliability and color rendering index. Let us discuss the role of the color indicator together.
Color rendering index: Generally, the color of LED lights is different from that of sunlight. It is known that the white light of a fluorescent lamp is purple at first, and then it emits white or other colors after exciting the phosphor.… Read More
