- Q:How does the LED bulb go with the power?
- voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,
- Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
- With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.
- 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:How to choose the bulb power?
- The basic types of bulb power are divided into two types: isolated and non isolated
- 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:What is the AC voltage of the LED bulb?
- The AC voltage of LED bulb is usually 220V, and the power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.The biggest market for LED bulb lighting is the civilian market, and the LED bulb is a new green light source to replace the traditional incandescent bulb. LED lamp has the advantages of energy saving, environmental protection, long service life, no stroboscopic, green and so on.
- Q:What is the 15 Watt lumen of the LED bulb?
- In general, every W is 60 to 100lm, the average is about 80lm, 15W is about 1200lm
- 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:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
- Q:Is it possible to manually weld LED bulb bulbs?
- If you can guarantee that you can add thermal grease just fill the gap without obstructing the normal contact, it is useful, but this process is very difficult for you to do, and the theory can improve the thermal efficiency of thermal grease, but actually you are not up to the process it is possible to reduce the thermal efficiency, you added more is to seek psychological comfort, you can on the heating plate welding of light, with one side of the thermal grease solder, such thermal effect is better
