Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
Q:LED bulb bulbs, do you need 3C certification now?
Simple bulb does not require 3C or CQC certification.Only with lampholders, and then judge according to the situation.
Q:Secret LED bulb bubble price difference why so big?
Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;
Q:Ordinary lamp LED bulb can?
As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.
Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
The cost is too high, the latter is better than the former, with long service life, there is a need bulb welcome to Taobao fry and sales of professional manufacturers of high power LED lighting lamp.
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:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
Q:What are the driving IC used in LED bulb?
M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..
Q:Detailed description of LED bulb lamp
Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
Q:What are the types of LED bulb?
According to the power points, LED bulb has 1W, 3W, 5W, 7W, 9W, 12W, 15W and other power, customers can choose according to brightness requirements.
