The luminous intensity is shorter than the light intensity, the international unit is candlelight (candela) shorthand CD, (LED explosion-proof light) other units are candlelight and branch light. 1cd or 1000mcd refers to the luminous flux emitted by a monochromatic light source (frequency 540X10×12HZ) per unit solid angle in a given direction (the radiant intensity in this direction is (1/683 watt/sphere).

You can use Kirchhoff's integral theorem.

From the nature of light, light is regarded as an electromagnetic wave field, and the light intensity at a point in the light field refers to the average energy flux density passing through that point.

Steradian is a unit solid angle, the fixed-point enterprise is located at a distance from the center of the sphere, and the area it intercepts on the sphere is greater than or equal to the square building area with the radius of the sphere as the side length.

When the light source radiates uniformly, the light intensity is i = f/(solid angle), the unit is sphericity (sr), f is the luminous flux, the unit is lumens, for a point light source i = f/(4).

Luminous intensity is for point light sources, or the size of the illuminant is less than the illumination distance.

This quantity indicates the convergent development ability of a luminous body to emit in space. It can be said that the problem of luminescent material intensity is that we describe how bright the light source is. 1000mcd=1cd

Overview of LED Lights

The function of explosion-proof lamps is simply to prevent explosions. Therefore, the use of explosion-proof lamps is very important for lighting in hazardous industries.

So, how does the explosion-proof lamp achieve the explosion-proof effect? The following Yaming Explosion-proof staff will briefly share with users. In order to achieve good lighting and explosion-proof effects,

The shell of the explosion-proof lamp is generally made of cast aluminum alloy, and the transparent part is generally made of tempered glass. The surface of the explosion-proof lamp can also be sprayed with anti-corrosion materials. So, how are explosion-proof lamps explosion-proof?

Can explosion-proof lighting effects be achieved just by using explosion-proof lamps produced from these materials? The inside of the lamp body of the explosion-proof lamp may generate arcs and sparks during use.

It is easy to cause an explosion when encountering flammable and explosive gases outside. Explosion-proof lamp housings can withstand internal explosions without damage. And can ensure that the internal flame gas reduces energy when it propagates through the gap,
