How many watts of watt bulb are the brightest in the 12 batteries of street lights

To determine how many watt bulbs are the brightest in a 12-meter street lamp, we need to consider the following factors: the capacity of the battery, the voltage of the battery, the power of the bulb, and the brightness of the bulb.

First of all, the capacity of a battery refers to the amount of electrical energy that the battery is able to store, usually measured in ampere-hours (Ah). The larger the capacity of the battery, the more energy it can store, and the longer it can be used.

Secondly, the voltage of the battery refers to the voltage of the battery's electrical output, usually in volts (V). Different batteries have different voltage outputs, and the common battery voltages are 12V, 24V, etc.

Then, the power of the bulb refers to the amount of electrical energy consumed by the bulb, usually measured in watts (W). The more power the bulb has, the more electricity it consumes and the brighter the light it emits.

Finally, the brightness of a light bulb refers to the intensity of the light emitted by the bulb, usually measured in lumens (lm). The brightness of the bulb is related to the power, and the higher the power, the higher the brightness.

To sum up, to determine how many watts of light bulb are the brightest in the 12 batteries of street lights, we need to consider the capacity of the battery, the voltage of the battery, the power of the bulb and the brightness of the bulb. According to the actual situation, we can choose the appropriate battery capacity and voltage, and choose a bulb with higher power to achieve the brightest effect. At the same time, it is also necessary to consider factors such as the life and cost of the battery to make a reasonable choice.

According to the battery capacity of 60 ampere, a 70W bulb can be installed, which should be regarded as the brightest.

12 hours.

The 12V20W bulb is powered by a 12V20W battery, and theoretically the current of the 12V20W bulb is according to the power formula, and the 20Ah battery should be able to make the bulb light up for nearly 12 hours.

Time (hours) = battery voltage (V) * battery capacity (AH) * 80% Power consumption (W) = hours, in the formula for calculating battery power time, 80% means that the battery can only use up 80% of the power, and the battery life is shortened by 80% after using photoelectric power.

CFLs cannot use 12V batteries to directly light CFLs, there must be an inverter that can convert 12V DC current into 220V AC current to drive CFLs.

The color temperature of the energy-saving lamp is: 6500K, daylight color, rr; 5000K, Neutral White, RZ; 4000K, cool white, RL; 3500K, White, RB; 3000k, warm white.

The color temperature is low: K temperature is 2700K 3500K. For example, when the sun rises before 8 o'clock in the morning, sodium lamps and candle lamps have a low color temperature, and contain more long-wave red and orange yellow light, and the light color is softer, giving people a visual warmth and warmth.

The color temperature is moderate: 3500K 4500K at K temperature. For example, sunlight after 8 a.m. or before 10 a.m. contains less orange light and more blue light, and the light colors are soft and bright, giving a clear and comfortable visual experience.

The power supply voltage of the energy-saving lamp is DC 12 volts, this situation is very simple, as long as the positive and negative poles of the battery are directly connected to the energy-saving lamp, it can be lit, but the 12-volt energy-saving lamp on the market is not easy to buy and is relatively high. Two. The power supply voltage of the energy-saving lamp is 220 volts AC.

This situation is relatively troublesome, you need to change the 12-volt battery DC voltage to 220 volt AC voltage, you can go to the electronic market or ** on the buy a 12-volt 220-volt inverter can convert the battery's 12-volt to 220 AC to supply power to energy-saving lamps, the power of the inverter depends on your battery and energy-saving lamps, generally buy 100 watts 200 watts is enough. **It's not expensive, just about 100 yuan. That's how I use it, I usually use solar batteries to charge the battery, and it's very convenient to use the battery to power and light up the energy-saving lamp when there is a power outage.

The 12V battery cannot directly light the energy-saving lamp, and there must be an inverter device to turn the 12V direct current into 220 alternating current in order to drive the energy-saving lamp (the question did not mention that it is the kind of energy-saving lamp, when it is an ordinary 220V energy-saving lamp).

Another 12V LED energy-saving lamp can be driven by a 12V battery.

To connect to ordinary household energy-saving lamps, you need to add a 220V50Hz inverter to change 12V to 220V. If it is a 12V lamp, just add a switch and connect it directly.

It's not enough to buy a 12V energy-saving light bulb.

12 How many watts can a 32A battery carry with a 12-volt LED light.

12 How many watts can a 32A battery carry with a 12-volt LED lamp Hello dear, solution: Set the current intensity of a 12-volt bulb to ia. Based on the electrical power equal to the voltage multiplied by the current intensity, it is obtained:

Battery power: 12 32 384 (watts). Power of the bulb:

12 i) A: Up to 3846 12i bulbs. Knowledge Expansion:

The power of the power supply must be greater than that of the electrical appliance. power, otherwise it will burn out the power supply, and there is a safety hazard. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

How long it lasts depends on the amount of current. If the current is 140 mA, then the power is 12 140 = 1680 watts =, here the bulb power is 140 watts =, and the time it can be used = hours.

Summary. Good evening, dear, it's like this, I just calculated that 21 12-watt bulbs with 220 current is enough.

Good evening, dear, it's like this, I just calculated that 21 12-watt bulbs with 220 current is enough.

Dear, yes, 21 bulbs 12 watts bulb = 252 watts.

Dear, because the electric power = the current and the voltage, we can calculate the current according to the formula of the loss of the fast: current = electric power voltage.

Dear, let's assume that the voltage of 220V remains unchanged, and the total current of the 21 12-watt bulbs is: buried current = 252 watts 220V = amps.

So, dear, 21 12-watt bulbs with 220 current is enough.

How many 12-watt bulbs can the 220 carry.

Dear, the 220 can carry about 182 12-watt bulbs.

Dear, that's the case, let's assume that the rated current of the 220V circuit is late I, and the voltage of each 12-watt bulb is 220V, so, dear, the current of each fiber bulb can be calculated as: I lamp = P lamp V lamp = 12W 220V

Then, dear, let's assume that the rated current of the circuit is 10A, so Hehe, dear, we can calculate the maximum number of bulbs that the circuit can support is: n = i i lamp = 10A 182 bulbs.

Dear, the number of bulbs needed for this problem depends on the rated current and power rating of the circuit, so I assume here that the rated current of the circuit is 10A

Take a 12-watt light bulb lit for 8 hours a day, for example, 365 days a year electricity:

12*8*365=35040 watts 1000=35 degrees.

If it is lit up for 24 hours a day, it is three times the above value.

Hello dear! I'm asking Mr. Xiao Liu is happy to serve you: 12 little ants auspicious time.

The 12V20W bulb uses a 12V20Ah battery for power supply, and theoretically according to the power formula of the 12V20W bulb, the 20Ah battery should be able to make the bulb light up for nearly 12 hours. The power of the battery is multiplied by the voltage, that is, the kilowatt hour, if ideally, it can be lit for 6 hours, but because the energy conversion cannot be 100%, as the power decreases.
