Q:The working principle of LED floodlight
Floodlights are one of the most widely used light sources in the production of renderings, and standard floodlights are used to illuminate the entire scene.
Q:LED50W flood light is on for 24 hours. How many years can it take?
If you are not in the bedroom, and not too close, then it will not have much impact, do not worry too much, the bedroom is not recommended to put the computer
Q:How much is the LED 100W floodlight now?
Depends on what kind of configuration, the market is relatively chaotic, and now there are 700 to 2000 yuan, a price, a cargo
Q:What is the 50W luminous flux of LED floodlights?
The LED lamp is generally 80-100 LM / W, 50 W flux is about 4000-5000 lumens.
Q:What's the difference between a LED projector and a LED floodlight?
Floodlights have no focus, no spot, just like torches, which can be evenly illuminated in all directions, and non directional point light sources.
Q:According to the brightness effect, the difference between LED light projector and LED floodlight
The floodlight is also called cast light lamps, cast light lamps with different floodlight is the projection angle of light above, but now many people confuse is not a standard to distinguish between them, his light beam is more uniform, the light source is relatively concentrated on buildings or landscape objects but now, can he made.
Q:LED lamp and metal halide lamp lighting height ratio, the better?
Led flood lights are full power, projected 10 metersLED floodlight is a point light source that can be irradiated evenly in all directions. Its range of illumination can be adjusted arbitrarily, and it can be shown as a picture of a positive eight body in the scene. Floodlights are one of the most widely used light sources in the production of renderings, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results. Floodlight is one of the most widely used light sources in the effect diagram. In the scene, many floodlights can be used together to produce better effects. Ling Chuang lighting, focusing on outdoor lighting projects, lamps and lanterns, good quality, cost-effective, recommended.
Q:How to choose LED floodlight?
The leakage current is also very important, LED floodlight is a one-way conductive luminous body, if the reverse current is called leakage, the leakage current of LED, the service life is short, the current is a little larger there can burn the bulb, so LED floodlight of this type of price is relatively low, lighting recommendations it is best not to buy this type of.
Q:What's the doorway to the LED flood light?
It is mainly composed of N layer formed by N semiconductor, P layer formed by P semiconductor and active layer in the center. When the applied positive bias, P area hole diffusion to the negative direction, into the active region, and electronic N area will spread to the positive direction, into the active region, when the electron and hole combination, will emit light spontaneously. When materials are used differently, light of different colors will be emitted due to different levels of energy, such as red, orange, yellow, green, blue, or invisible light.
Q:Under what circumstances will the LED lights be burned and the customer is using floodlights 48W wide pressure (AC100~240V)?
48WLED lamp heating situation is quite large, often as the use of light projection, in the surface layer often covered with things, the epicenter of the case is easy to burn lights.
