Q: 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

Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q: LED bulb with what type of LED beads?: The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.

Q: 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.

Q: What is the 15 Watt lumen of the LED bulb?: The general high-power lamp for 1W 80ML 15W ~ ~ ~ is about 1200 lumens, but you use good chip ~ higher lumen.

Q: What are the driving IC used in LED bulb?: Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.

Q: What's the reason for the LED bulb strobe?: Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q: LED bulb bulbs, do you need 3C certification now?: No, this is a light source, not a lamp. It can only be CQC voluntary certification

Q: How to identify Ic constant current LED bulb?: Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
