FAQ

Secret LED bulb bubble price difference why so big?
Structure. LED heat dissipation is very important, good bulb will be equipped with radiators, inexpensive, and its life can be imagined
Ordinary lamp LED bulb can?
Absolutely, without any effect. It can be directly across to look at the opening of several inches.
What's the cause of the noise during the aging of LED bulb bulbs?
The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.
LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
Power supply has noise, it is the design of transformer, winding, the design of switch power supply.. Engineering reference..
How to choose the bulb power?
LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.
What does the LED bulb patch mean?
In order to obtain high power LED light source, high brightness, the manufacturers to power direction in LED chip and package design. At present, the LED package can withstand W power has emerged. For example, Norlux series of high-power LED packaging structure for the hexagonal aluminum plate as base (the conductive) multi chip combination. The base diameter of 31.75mm, light emitting area is located in the central part, a diameter of about mm (0.375 * 25.4), can accommodate 40 LED tube core, at the same time as the aluminum heat sink. This package uses conventional tube core combination of high density packaging, high luminous efficiency, low thermal resistance, high in light output power flow under high electric. Is a kind of promising LED solid state light source.
LED bulb PC, will the white cover affect the color temperature of the finished lamp?
PC Ivory lampshade, because of the low price, it is recommended to use light diffusion cover, so this should not be the problem
How to identify Ic constant current LED bulb?
Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
