Q:What is the display index of the LED lamp?

The degree to which an object's color is rendered is called color rendering.Usually called the color rendering index (Ra)A light source with a Ra value of 100 indicates that the color displayed in the light of the object is consistent with that under the standard light source.

Q:Is the price of the street lamp factory in led the same?

The price of street lamps at the LED street lamp factory is the same as that of the foreign ones. LED street lamp external price = cost + profit. The cost is fixed, that is, profits will change, in addition to street lamps manufacturers require profits, the salesman will be appropriate adjustments, this depends on the salesman personally

Q:Is the street lamp good with LED or solar energy?

Hello The two concepts, the LED street lamp and the solar street light, are in themselves no conflict, just as you think, are you wearing a black coat or black shoes today? The actual two do not conflict.

Q:LED street light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?

The 14 LED are connected in series to calculate a set, and then there are seven groups, which connect the seven sets of positive and negative electrodes to the negative pole, i.e., the seven groups are connected in parallel, and this is the meaning of "14 strings of 7".

Q:What do you pay attention to when choosing LED street lamps?

First, we should pay attention to the relevant photoelectric properties (such as light type, luminous flux, luminous efficiency, color temperature, power, rated voltage and current parameters);

Q:How many volts is the 42wled solar street light?

The street more than 40 Watt in general should be the 24 volt system needs two batteries in series

Q:LED lamp with air leakage to help the thunder?

There is no air leakage with LED lights for the role of lightning protection. The function of the switch of leakage air breaker is to work by current. To enable the street circuit with lightning protection function, must use a surge protector, installation and circuit breaker in parallel. It works by limiting the overvoltage and cutting off the circuit as long as the voltage exceeds the set point to protect the electrical equipment.

Q:What is the voltage of the street lamp?

The normal voltage of the street lights is also 220V, and his risk is the same as that of other common lighting points. But now some street lighting voltage may be slightly higher.

Q:LED good or low frequency electrodeless lamp?

LED is a point light source, and electrodeless lamp belongs to the area light source. LED has a strong advantage in low voltage, but it is not mature to make high voltage technology.

Q:What heat sink is best for LED street lamp radiator?

Is natural heat dissipation, what is called natural heat dissipation, that is, rely on the lamp's own radiator to dissipate heat, and now most of the market is fin type heat sink, this advantage lies in the cost point, passive heat dissipation time. However, the disadvantage is that the heat dissipation is very slow, far less than the high-power heat dissipation requirements. Good service life is less than 2 years. But recently, the market has a kind of through-hole type heat radiation lamp, break the traditional heat dissipation concept, increased the heat dissipation surface, let the air form convection. The cooling effect is remarkable. You should be interested in discussing LED lighting technology, so you can leave a contact. I'm technical. Hope to be adopted
