Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
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.
Q:How to choose the bulb power?
If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.
Q:What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Q:LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:How did the trademark on the LED bulb go up?
Laser printing and screen printing, pad printing can be, look at the needs and equipment.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Anti torque test is carried out using only suitable for torque meter, torque test, lamp holder should be firmly bonded on the lamp or lamps used to purchase spin spin out parts, E26 and E27 for 3N*m.
Q:What's the cause of the noise during the aging of LED bulb bulbs?
The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
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:Where can LED bulb be used?
The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.
