Common solar street lamps light source of export what kind of lamps are there?

What kind of common solar street lamps light source are there? Currently using the sodium lamp and LED lamps and lanterns. 1, compared with the LED lamps and lanterns is higher than the high-pressure sodium lamp, color can create a more comfortable environment, so as to improve the safety of driving, security and social security.



what kind of common solar street lamps light source are there?

now are using sodium lamp and LED lamps and lanterns. 1, compared with the LED lamps and lanterns is higher than the high-pressure sodium lamp, color can create a more comfortable environment, so as to improve the safety of driving, security and social security.

leds do not contain harmful elements such as mercury, sodium, not cause environmental pollution.

LED high luminous efficiency, the tests of 63 W bulbs and lamps to meet the city branch of city road lighting design standard standard, so as to minimize power consumption, save energy.

LED the long service life of lamps and lanterns lanterns, can save maintenance cost. 2, but the LED lamps and lanterns also has its disadvantages. The homogeneous degree of the LED lamps and lanterns is low, the road of 20% higher than that of the same mileage, than the high-pressure sodium lamp with light -

30%, lamps and lanterns is 3 - higher than that of high pressure sodium lamp 4 times the price, the initial cost of investment' The initial investment cost is refers to the total cost of the investment when the actual payment, including taxes, fees and other related expenses. 。 。 】 Much higher than the high-pressure sodium lamp, and because to increase the number of lamps and lanterns, although the maintenance cost and power consumption is reduced, but the overall operating costs than

high pressure sodium lamp. The LED light source directivity is strong, visual glare will be higher than the high-pressure sodium lamp. 3, comprehensive comparison: economic benefits: in the current price of lamps and lanterns, LED the investment cost and operation cost of much higher than the high-pressure sodium lamp. Social welfare: from the environmental consideration, LED lamps and lanterns high luminous efficiency, do not contain mercury, sodium and harmful elements, not cause pollution to the environment, more in line with the green lighting product lines, has been in a good social effect. Scope of application: suitable for road lighting applications, because of the limitation of uniformity and high power laser source with the technology level of LED lights LED light source, now unable to be applied on the main road and other important sections, is only applicable to municipal lighting

low leverage, such as rural roads, due to the large size street lights maintenance inconvenience, internal use LED street lamp' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Maintenance can be greatly reduced, and because of its high color rendering, can build a more comfortable visual environment.
