## How many watts is the solar street lamp?

Solar street lamps are usually about 10 watts. According to different types of solar street lamps. 5 meters of solar energy, etc., the light source is between 8 and 18 watts. 6 meters of solar energy, etc., the light source is between 18 and 30 watts. 7 meters solar road, etc., light source between 30 and 42 watts. 8 meters of solar energy, etc., the light source is between 42 and 60 watts.

Generally, the power of roadside solar lamps is relatively small, generally between 1-5 watts. The power required for cooking with a rice cooker with photovoltaic power generation is determined according to the specific power of the rice cooker. Generally speaking, the power of an electric rice cooker is between 500W and 1000 watts, so it takes between 500W and 1000 watts to cook with photovoltaic power.

If the lamp pole is 8m, then you can use 56W or 60W solar street lamp. If it is 10m, you can use 80W solar street lamp, 12m or so 100w solar street lamp. No matter how high the lamp pole is, you are advised not to install solar street lamp.

The wattage of rural solar street lamps is generally 15-40W, because the wattage of solar street lamps is also combined with the specifications of solar panels and solar batteries, and generally will not be particularly high-power. Jhzm88. Com, you can ask Jinghui lighting for solar street lamps to see if they have any smaller wattages.

In general, the 6-meter solar street lamp is generally equipped with a standard light source of 30Wled.

The power of solar street lamps can reach 60 watts. They usually use semiconductor modules and are made up of silicon solar panels, LED light emitting elements and small rechargeable batteries to provide good night lighting.

## Help me calculate the amount of lighting in the factory building!

1. The general calculation method is: illuminance * area / (light efficiency power * utilization factor * maintenance coefficient) = the number of lamps and lanterns. This is the emergency calculation method. It is recommended to use professional lighting software to calculate, which is fast and accurate.

2. the lighting of the factory building is about 3 watts per square meter. If a lamp is used in a 300-square-meter factory building, it will use about 500 to 800 watts, so the lighting is not uniform enough, so you can generally use 10 lights, one lamp is 50 to 80 watts, so the lighting of the factory building is about 3 watts per square meter.

3. In fact, the distribution freshness analysis of the contrast degree is needed, which can be calculated, which is called point-by-point calculation. It is calculated according to the beam distribution data of the lamps and lanterns, one meter or half and a half meters.

## General lighting one square meter how many watts of brightness is appropriate?

One square meter and one watt. The luminous efficiency of LED light is more than 100 lumens / watt, while the average incandescent lamp can only reach 40 lumens / watt, and the energy-saving lamp hovers around 70 lumens / watt. Therefore, with the same wattage, the effect of LED lamp will be much brighter than incandescent lamp and energy-saving lamp. A 1-watt LED lamp is as bright as a 2-watt energy-saving lamp.

Square about 70-90 lumens we take the middle to fill 80LM, if you use LED lighting effect 120LM/W, then about 1W can illuminate 5 square meters, if you use LED lighting effect 100LM/W, then about 1W can illuminate 25 square meters.

A masterpiece of one square meter or one watt is almost enough. So 8 square meters, then 10 watts to 15 watts or so, for the bedroom, 18 watts is almost enough.

Choose the wattage according to the area of the living room: generally speaking, the lighting source of the living room is recommended to be calculated according to the need for 1530 watts per square meter. For example, for a 15 square meter living room, the lighting requirement is 15×15=225 watts. So you can choose the corresponding lamp wattage according to the area of the living room, such as 100 watts, 150 watts, 200 watts and so on.

A square takes a few watts of light. Usually, a square installation uses a 5w LED tube lamp, the brightness is bright enough. The lighting effect of _ ED lamp is very good, and the brightness of the lighting is very bright. Save electricity and energy. LED energy-saving lamps are used in most homes and offices and public places.

Interior decoration will generally recommend you to use 10W-15W between enough, want to buy indoor lights, recommend you to see the Moon Shadow Caden, the use of good materials, the appearance looks grade.

## How many watts of lighting do you need per square meter?

1. One square meter and one watt. The luminous efficiency of LED light is more than 100 lumens / watt, while the average incandescent lamp can only reach 40 lumens / watt, and the energy-saving lamp hovers around 70 lumens / watt. Therefore, with the same wattage, the effect of LED lamp will be much brighter than incandescent lamp and energy-saving lamp. A 1-watt LED lamp is as bright as a 2-watt energy-saving lamp.

2. A masterpiece of about one watt per square meter is almost enough. So 8 square meters, then 10 watts to 15 watts or so, for the bedroom, 18 watts is almost enough.

3, generally speaking, if it is an ordinary family, the choice of incandescent lamp in about 30 watts can meet the needs of their families. Because the average family usually has a height of 5 to 8 meters from the top to the younger brother, the area of a home should generally be less than 30 square meters.

4. Less than 12W. The lighting power density of general store business hall should not be more than 12W per square meter. In other words, the number of watts per square meter should be less than 12W. Mall lighting and uniform distribution, high color rendering, generally speaking, in the mall area, when the height is more than 6 meters, the use of point light source.

5. The lighting power density of general store business hall should not be more than 12W per square meter. In other words, the number of watts per square meter should be less than 12W. Mall lighting refers to the lighting technology used in department stores, shopping malls corridors, passageways, specialty stores, bathrooms, conference rooms and other places of lighting.

## In general, how many watts per square meter is suitable for lighting in the production workshop? The height of the lamp is 6 meters above the ground, and the length of the workshop is.

1. General lighting is 3 to 5 watts per square meter. The W LED lamp is equivalent to about 5W incandescent lamp, which is similar to the energy-saving lamp. What we are talking about here is to refer to the Development trend of Lighting Light Source in the August issue of Architectural Electrical.

One square meter and one watt. The luminous efficiency of LED light is more than 100 lumens / watt, while the average incandescent lamp can only reach 40 lumens / watt, and the energy-saving lamp hovers around 70 lumens / watt. Therefore, with the same wattage, the effect of LED lamp will be much brighter than incandescent lamp and energy-saving lamp. A 1-watt LED lamp is as bright as a 2-watt energy-saving lamp.

3. There should be sufficient natural lighting or artificial lighting in the workshop or work place. The lighting coefficient of the workshop should not be lower than the standard IV, the mixed illuminance of 636f707962616964757a686964616f31333365643661 in the working face of the inspection place should not be less than 540lx, the working face of the processing site should not be less than 220lx, and other places should not be lower than 110lx.

4. Article 3 the illuminance value of general lighting in mixed lighting should be selected according to 5%-15% of the illuminance value of mixed lighting, which should not be lower than 30Lx. However, when using high-intensity gas discharge lamp, it should not be lower than 50Lx. Article 4 the standard values of illuminance on the work surface of general production workshops and workplaces may be adopted in accordance with Appendix II to this standard.

5. The height of the factory is 5 meters. Minus the height of the lamp itself, the actual height of the led factory lamp is only 5 meters from the ground.

6. According to the national standard “Architectural Lighting Design Standard” GB 50034tel 2004, ordinary office, illumination 300lx, high-grade office, illumination 500lx. In the design, the power density of the illuminance design of the high-end office is 15W~18W/ square meters, and the power density of the ordinary office is 9W~11W/ square meters.
