What is Metal Halogen Light?

The metal halide lamp is a discharge lamp that produces arc discharge in the mixed vapor of mercury and rare metal halide. The metal halide lamp is a discharge lamp made by adding various metal halides to the high-pressure mercury lamp.

Generation light source.

The lighting adopts sodium scandium metal halide lamp.

The metal halide lamp has the characteristics of high luminous efficiency, good color rendering performance, and long life.… Read More

Guideline for Billboard Lighting

Billboards are everywhere in our lives. Large and small ones stand in front of us, and the night lighting of billboards has become a major focus of billboards. At present, metal halide floodlights are the main lighting of billboards, and the power is 250W / 400W. However, with the sharp decrease of global resources, energy conservation has become an urgent matter LED light source emerges as the times require.… Read More

RGB color in power

When it comes to the grievances and grudges of white LEDs, we cannot fail to mention RGB and white LEDs. Both of them have the same goal. They all hope to achieve the effect of white light, but one is directly presented in white light, and the other is in red, green and blue. Mixed light. The purity of one party is not enough, the price is too expensive, and the color of the other party is beautiful.… Read More

Difference Between Lux and Lumens

Lumen is the abbreviation of luminous flux, or Lumens. The unit of illuminance is lux. The transliteration of English lux can also be written as lx.

It is difficult to achieve a brightness of 3000 lux, and it is usually unnecessary. If you are using a “lamp”, an ordinary 40-watt lamp can reach 3000 Lux at a distance of about 0.2 meters.… Read More

NFL Field Lighting Standard

The NFL requires 5600 Kelvin of CCT.

The current NFL sports field lighting standards include:

• 2500 lux for NFL.
• 1500 lux for collegiate-level
• 500 lux for high school football fields.

The rugby field lighting increases the area where lamps cannot be arranged, which is intended to protect players and referees from the effects of glare.… Read More

What are the lighting Requirements for Portrait Photography?

Portrait photography is not as difficult as imagined. It is necessary to master the basic knowledge of using light
before getting started.

1. The light texture and color temperature are different in different regions and time periods. Then the traditional indoor studio lights should choose some brands with stable output, good light quality and accurate color reproduction.

The Advantages of LED Lights for Fish Tank Lighting

• High brightness: The spectrum of LEDs is almost entirely concentrated in the visible light frequency band, and the efficiency can reach 80%-95%, while the visible light efficiency of incandescent lamps is only 10%. The theoretical limit efficiency of the visible light of the LED can reach at least 500lm/W, which has a considerable energy saving effect.

The Definition of Explosion

Explosion is a matter from one state, after physical or chemical changes, suddenly into another state, and release huge energy.
The energy released rapidly will make the surrounding objects suffer violent impact and damage.

Three conditions for explosion

1) explosive substances: substances that can react with oxygen (air), including gas, liquid and solid (gas: hydrogen, acetylene,
methane, etc.;… Read More

The definition of Explosion-proof light

Explosion-proof lamp refers to a lamp used in dangerous places where flammable gas and dust exist, and can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the flammable gas and dust in the surrounding environment, so as to meet the requirements of explosion-proof. Also known as explosion-proof lamps, explosion-proof lighting.… Read More

Hangar Design Requirements

All the design of the hangar must take into account the local climatic conditions and biological activities. In any case,
the safety of the aircraft and related personnel must be ensured. The hangar needs to have the temperature and environmental conditions for the mechanics to safely and comfortably complete the mechanics service business throughout the year.

The interior lighting design of the hangar must meet the requirements of machine repair, and the hangar design must ensure that it does not endanger human health and safe working conditions.… Read More
