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: The difference between the gold halide lamp and the LED lamp in explosion proof floodlight: Now everyone began to use LED light source CCd297 explosion-proof floodlight, mainly energy-saving, long life, compact appearance of lamps.

Q: What brand of LED floodlight, light quality is better, light efficiency and high?: Its brand, its quality, its light effect is the need to buy more elements, ran around the wholesale market, small and large exhibition lighting exhibition last year I harvest a LED floodlight, bring the excitement, this year's autumn exhibition (Fourteenth China - Guzhen International Lighting Fair) I still like to find my treasure.

Q: What is the difference between the high-power LED floodlight and the LED outdoor projection lamp?: About LED floodlights and projection lights, many manufacturers are now ambiguous about this definition, and some are also known as floodlight in floodlights

Q: What are the applicable ranges of LED flood lights?: The key is to look at your customer needs, specifically ask World Expo LED lighting manufacturers Sheng lighting, their engineers will give you an analysis of the very clear

Q: Does the LED explosion-proof floodlight work well? Can I use it in a chemical factory?: LED explosion-proof floodlights can be used in chemical plant, but it should be noted that the ignition temperature of hazardous gas in chemical plant, for explosion-proof electrical products are surface temperature, surface temperature if the ignition temperature explosion-proof lamp more than dangerous gas, can not be used. Attention should be paid to the explosion-proof signs and temperature groups.

Q: How long is the life of a LED50w floodlight?: LED 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, if at high temperature will also affect the long-term life. LED floodlight housing, heat, water, dust, etc. will also affect the life expectancy, so generally speaking, 5 years.

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?: Increase the power of the driving power and reduce the working current of the LED module. The temperature of the power supply and the LED module can be lowered simultaneously.

Q: The site of the gantry crane above LED can be installed floodlights or floodlights in general?: Yes, the light will be good, at least 100W, this price is uneven, you can look at the price on the internet.

Q: What's the difference between a LED projector and a floodlight?: Now more use of frosted treatment or add some materials, with the development of these years, the transmittance of the performance of further improved. SMD LED mostly low voltage drive, the use of aluminum substrate cooling. The LED light now used is not specifically for lighting, and some are used for very good projection effects.
