Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:Will the power of the LED bulb grow longer and longer? Why?
Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.
Q: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
Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
The most direct and simplest answer is the power problem.
Q:Is there any flicker in the LED bulb?
First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!
Q:What are the types of LED bulb?
The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.
Q:How did the trademark on the LED bulb go up?
Laser printing equipment is generally printed up, so that the ridge up color is not so deep, but also can not wipe off
Q:How does the LED bulb look good or bad?
A light source, two power supply, three workmanship.Online shopping, I strongly suggest that you buy some reliable.
Q:Choose which light bulb LED bulb is the healthiest
Choose LED lights, first, no strobe, strobe damage to the eyes, second color index to be high, true and clear. For the quality, choose to heat better, high power factor, so that the relative power of the lamp, power saving, durable
Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
The first is Aluminum Alloy better heat dissipation, aluminum is relatively high, and made products, together with the positive effect is not the same, in addition, the wick and the circuit there will be differences, this will also affect the application of life and feelings.
