As a public equipment for guiding and lighting roads, solar street lamps have become an indispensable part of our lives. Moreover, with the continuous development and progress of science and technology, the function of street lamps is still stronger and stronger.
As a point light source, if the planning is reasonable, the LED street lamp can directly deal with the problem of secondary light acquisition and light loss that the traditional spherical light source must rely on luminescence; The uniformity of the lighting surface can be controlled. Theoretically, it can be completely uniform in the target area, and it can also avoid the light waste in the phenomenon of "light under the lamp" of traditional light source; Color temperature can be selected, which is also an important way to improve efficiency and reduce cost in different applications; There is still much room for technological progress.
What are the advantages of LED street lamps
At present, the market share of LED street lamps is very high. Almost all the lights you can see on the road are led street lights. LED street lamps have been very popular and must have high-quality positions. This paper summarizes some high-quality LED lighting. Will you be excited after reading it?
1. Long application cycle
The super long service life is more than 50000 hours, more than 50 times that of traditional tungsten filament lamps. Led adopts highly reliable advanced packaging technology - eutectic welding to fully ensure the ultra long service life of LED; If the energy-saving lamp is often turned on or off, the filament will quickly turn black and decompose. The service life of LED street lamp can reach more than 50000 hours, which can be said to be "a hundred wastes waiting for prosperity" of traditional lighting.
2. Price advantage
With the continuous development and promotion of LED lamps and the continuous progress of luminous power, the cost of LED has been well controlled and the price is getting cheaper and cheaper.
3. Green environmental protection
No lead, mercury and other polluting elements, no pollution to the environment; There are no harmful substances of mercury. The assembly of LED bulb is easy to disassemble and assemble and can be recycled by others without recycling by the manufacturer. Reduce line loss and do not pollute the power grid. Power factor ≥ 0.9, harmonic distortion ≤ EMI, reach the global goal, reduce the power loss of power supply line and avoid high-frequency interference and pollution to power grid.
4. Energy saving economy
Super bright high-power LED light source and high-power power supply are selected, which can save more than 80% electricity than traditional incandescent lamps, and the brightness is 10 times that of incandescent lamps under the same power; The energy consumption of white LED is only 1 / 10 of that of incandescent lamp and 1 / 2 of that of energy-saving lamp.
5. Strong anti-interference ability
Impact resistance, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. Without filament and glass shell, traditional lamps and lanterns have no fragmentation, no damage and radiation to human body.
6. High safety factor
Safe and reliable operation under low thermal voltage. Surface temperature ≤ 60 ℃ (ambient temperature Ta = 25 ℃); PWM constant current technology is selected, which has the characteristics of high power, low heat and high constant current accuracy.
7. Strong applicability
General specification lamp cap, which can directly replace the existing halogen lamp, incandescent lamp and fluorescent lamp; Extensive voltage planning, global. 85V ~ 264Vac full voltage planning constant current to ensure that the service life and brightness are not affected by voltage fluctuations.
8. The packaging structure is conducive to planning and development
High power LED plane cluster packaging, integrated planning of radiator and lamp holder. Fully ensure the heat dissipation requirements and service life of LED, fundamentally meet the arbitrary planning of LED lamp structure and shape, and have the remarkable characteristics of LED lamps; Comprehensive planning of lens and lampshade. The lens has focusing and protection functions, which avoids the repeated waste of light and makes the product more concise and beautiful.
9. Good visual effect
Pure DC operation eliminates the visual fatigue caused by the stroboscopic of traditional light source; Light distribution technology can expand LED point light source into regional light source, increase luminous surface, eliminate glare, improve visual effect and eliminate visual fatigue.
10. Photosensitivity
The luminous power can reach 1101m / W, a variety of color temperatures can be selected, with high color rendering index and good color rendering.
