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 bulb PC, will the white cover affect the color temperature of the finished lamp?
I've got my lighting engineer to give you a professional answerBecause the light barrier is selective for light waves, that is to say, the transmittance of light at different wavelengths is inconsistent. When the lamp cover is covered, the luminous spectrum of the light source is changed because of the filtering of the lampshade, and the color temperature certainly has certain change.Professional lampshade company should have the detection of the passing rate of different wavelengths. Is your lampshade provided by professional lampshade company?
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
Q:What advantages does LED bulb replace energy saving lamp?
The LED lamp is solid-state lighting, if all LED lamps a year remaining nearly three electric power Three Gorges hydropower station, the country.
Q:What's the difference between a glass cap for a bulb and a PC hood?
Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.
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:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.
Q:What is the 15 Watt lumen of the LED bulb?
LM, refers to a candle (CD, Candela Candela, unit of luminous intensity, the equivalent of an ordinary candle light intensity) in a solid angle corresponding to the spherical cone ball (1 square meters of the unit sphere radius of 1 meters on the representative point of view, the corresponding section in the center angle of about 65 degrees the total emission flux) on the.
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
The second continued the problem: welding line, this work continued not done!
