What is the luminous flux of LED30W solar street lamp?

At present, the more common led light source 1w 45mil luminous flux is between 110lm and 130lm (this is tested at rated 25 degrees at room temperature, in the actual application is certainly not to reach), the regular 30wled products are a lens for secondary distribution of light, even the best lens will also have a good light loss, good quality lens, The loss is 10%, the ordinary loss is more than 30, the common 30w led street lights are traditional lamp types, there are glass lenses outside the lamp, the light loss is higher, so the current more ordinary street lights have a conventional calculation method is the lamp bead per w lumens multiplied by 0.7 is the actual luminous flux of the lamp, the second luminous flux *0.6, Good quality luminous flux *0.75, this is the approximate calculation method.

If the accurate calculation method needs to be tested in a professional test center, our products are tested in Shanghai electric light source testing Institute, and the corresponding test data are satisfactory.

Ten cities ten thousand Lights" project use products.

Transparent lampshade made of imported polycarbonate injection molding, high strength, good light transmission.

High-power LED street lights have a long service life, and the light source life is more than 50,000 hours, which is 5 to 10 times that of traditional lights. The LED light source uses the current technology's most successful white 1W package, the surface is welded on a 2mm thick aluminum-based circuit board, and then the aluminum substrate is installed on the radiator plane, which can ensure that the heat is quickly transmitted to the radiator. In addition, the integrated design of radiator and lamp shell fully guarantees the heat dissipation requirements and service life of LED. The advanced packaging process ensures the high reliability of the LED, and the good heat dissipation ensures that the LED works at the allowed temperature, and the combination of the two fully guarantees the long service life of the LED.
Modular integrated design. Can be arbitrarily combined into different power and brightness requirements of the product, each module is an independent light source and interchangeable, local failure will not affect the normal work of the entire lamp, convenient disassembly and maintenance, saving maintenance costs.

The appearance is thin and light, which can effectively reduce the wind resistance, reduce the load of the lamp pole, and enhance the safety factor.

Low glare and light pollution: The illumination Angle of the LED light source can be designed according to the needs, which can greatly reduce glare and light pollution, and can greatly improve the effective utilization rate of light.

The operating voltage is low, and its advantages are:

(1) It will not cause the lampshade to black as the ordinary street lamp due to high pressure adsorption dust

(2) it is safe and reliable.

The working temperature is low, the LED light source is a cold light source, and when the heat dissipation is good, the working temperature is lower than 60oC, which will not cause the lamp shade to age yellow
Start without delay. Power up to normal brightness, no need to wait, eliminating the traditional street lamp start time is long and repeatedly start the problem.

No flash frequency. Pure DC operation eliminates visual fatigue caused by stroboscopic traditional street lights.
Impact resistance, strong seismic force, no filament and glass shell, no problem of traditional light fragmentation.
High color rendering index, good color rendering. The presentation of colors is more realistic and vivid.

A variety of colors and temperatures are available. It can meet the requirements of color temperature in different occasions.
Green environmental protection. Does not contain lead, mercury and other polluting elements, no pollution to the environment.
Wide input voltage, PWM constant current technology, high efficiency, low heat, high constant current accuracy.

Combined with solar power generation, the use of LED low voltage work, power size adjustable (dimming), high luminous efficiency and the advantages of energy saving and environmental protection, can produce more cost-effective solar lighting products (lamps).

High luminous efficiency. The efficiency of LED emitting light under existing conditions is 90-100lm/w. The energy-saving effect of the street lamp is obvious, compared with the traditional high-pressure sodium street lamp, under the premise of obtaining the same road illumination, the energy saving is more than 60%.
The protection level is IP65.
