Q:About LED tube light to shoot the light of common sense
LED lamp bead are dc low voltage, single grain lamp bead generally around 3.3 v voltage can light up, general household LED light has many grain of lamp bead, most of them are in series, no matter which kind of LED lighting needs to be in the form of a voltage conversion device, the voltage conversion device also has a built-in external, have stable manifold has regulated form, useful integrated circuit do useful discrete component, with complex circuit has simple circuit, there are lights and conversion circuit package together also have lights and conversion circuit of separate, anyway is multifarious, various countries now also does not have a specification, each manufacturer yourself, just do what want to make it, so they bring inconvenience to the user, so the home LED light damage, it is difficult to buy the same, every time in the lamp will also ask professional to listen to, you say the problem is not surprising, is likely to be a built-in driver, another oneself need plus drive without a driver.
Q:Led lamp have drive, don't drive, what's the difference?
Don't have to drive LED lamps and lanterns, the choice of the LED will be similar to Seoul, South Korea, 220 v LED semiconductor, there is no drive LED lamps and lanterns is non-conforming
Q:Led to shoot the light is broken how to change
Nails dig is commonly used in the edge of the lamp tube (position) linking to the smallpox condole top, a little bit hard pull became one! Two used to locate the wire spring clip!
Q:The led lamp has been dark bright
Switch to the zero line, should be a wire into the switch, do you have the leakage floor on a line, so it caused the leakage current, the LED can shed light on small electricity.
Q:Does the LED light have to be transformer?
There are two kinds of leds to shoot the light, the 12 v power supply voltage and 220 v power supply voltage. If the power supply voltage is 220 v, without additional transformer, lamp has a built-in transformer.
Q:LED to shoot the light, heat sink, aluminum alloy profiles and die casting aluminum radiator which is better?
Profile of the general than die-casting aluminum is better, but now there is a cold forging is also good, but I still want to see the structure whether reasonable!
Q:Glass in general so there is no relationship
Say that it is difficult to calculate, but you missed a bit, color rendering, the curtain of your original color is very full, the result under the low LED light color, guests watch the curtain is color distortion, what do you think the guest will buy Do you store this product in addition to, because there are too many styles, dizzy, let a guest see need to change on the scene illumination do, such as the administrative levels of light
Q:What's the reason why LED lamp explosion?
I come to the conclusion: your power supply voltage abnormal! Possible reasons: with your power supply system of a steal, (often at night, more time is that a) steal operation make the zero line suddenly dangling leads to voltage surge, relatively high voltage regular bulbs, not necessarily immediately, overflowing LED lamps and lanterns is very sensitive to voltage, slightly on the high side is easy to burn off one of the components (often capacitor). search Suggestion: immediately report power supply company, one night about the same time to check the meter box line condition!
Q:Led to shoot the light color temperature 3000 k what do you mean who knows
Color temperature (colo (u) r temperature) is visible in photography, video, publishing, and other fields has important application characteristics. Light source color temperature is by comparing the color and theory of thermal blackbody radiator. Hot blackbody radiator with the colour of the light source to match the kelvin temperature is the color temperature of light source, it is directly associated with Planck's blackbody radiation law.
Q:What is the difference between LED to shoot the light and PAR light
The lamps and lanterns of shoot the light is a highly concentrated, its light is a specific goal. Mainly used for special lighting, for example to emphasize a very tasty or is a very interesting place. Can be applied from the light source, location, and price comparison to distinguish the two kinds of the characteristics of the lamp.
