Q:Why can't the voice switch control the time of the LED bulb?

Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds

Q:What are the characteristics of LED bulb?

Life is more than ten times longer than incandescent, power consumption is 1/2 of ordinary light bulbs, fast response, generally 10-7 - 10-9s, color clear, recognizable performance, good vibration resistance, now the price of LED lamp is relatively high

Q:LED can the bulb be used in the bathroom?

of couse Yes, but LED kitchen and toilet light is recommended

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:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?

You should say that the bulb of the bulb, usually PC material.

Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?

A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;

Q:What's the difference between a glass cap for a bulb and a PC hood?

1, impact strength comparisonPC and glass is the biggest difference resistance shock, PC is transparent plastic, the most resistant to impact, smashing not broken.Similarly, PC is 200-300 times the impact resistance of glass. PC is 30-50 times the impact strength of PMMA acrylic.

Q:Want to find common features, unified purchase accessories repair!

The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis

Q:LED how does the bulb return electricity?

maybe because Make the question clearWhat is the return current?

Q:What does the LED bulb patch mean?

The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.
