Q: What are the 50 and 70 degree lenses for LED floodlights?: The general lens of a LED floodlight is "90 degrees - 120 degrees"",Lenses such as 50 - 70 degrees, if they are "at the same distance", must be narrower,

Q: What do you mean by "near distance attenuation" and "far distance attenuation" in 3DMAX floodlight?: Near attenuation: used to avoid light from a light source.Role: control the light source and object too close, close to expose serious situation..

Q: What is the use of flameproof flameproof lamps for mines?: Performance characteristics:1 、 light weight, small size, beautiful, easy to operate.2, flameproof highest explosion-proof level, in the coal mine industry flammable and explosive places security work.3, the light source adopts Germany's famous brand, long life, reliable performance, the average life of the bulb can reach more than 10000 hours.4 、 apply advanced optics and lighting principleThe design of transparent parts, soft light, illumination uniformity, no glare, no ghosting, effectively avoid the operation, construction personnel discomfort and fatigue.

Q: LED floodlight shell is what material? Is it corrosion proof?: Cast aluminium.Corrosion prevention depends on your environment. Usually 3 years is good for outdoor advertising. The first problem of the shell is waterproof apron. Usually, aprons are used in 8 places, such as floodlight (floodlight).

Q: LED floodlight single lamp and COB integrated lamp, LED light which is better?: The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.

Q: What's the difference between a LED projector and a LED floodlight?: A light source having a focus, spot, and illumination in a particular area.

Q: How much is the LED 100W floodlight now?: 100W LED flood light rarely, very few single light, it is integrated light source, low not more than 1000, expensive to more than 2000. But now most of the flood light housing is the previous traditional appearance, the heat done well not much ~!

Q: How long is the life span of the lED high-power floodlight? Is there a factory that can solve his problem of heat dissipation?: The current LED flood lights are LED modules with integrated light sources, and the heat is concentrated in one location. So there is no cost-effective program can be resolved. Water cooled radiator or vacuum radiator (average temperature plate) can be solved but the cost is too high.

Q: How long is the life of a LED50w floodlight?: ED lamp beads Jingyuan general 50000H, but if the equivalent matching power supply is inferior to may not to this time, and the use of the environment will also affect the life span

Q: Do you use spotlight for car led, or floodlight?: Indoor astigmatism should be better, according to the more spacious, indoor brightness requirements are not very bright, a little wider, and small lights are also bright light, the reason is not explained, in short, in addition to headlights, other bulbs are to diverge a little!
