At present, China's solar street lighting industry is voluminous and has fierce competition for products. In addition to the high-end products of well-known brands, the average cost of solar street lamps has great pressure, but the rising cost of upstream capital factors and rising labor costs will be positive. To the extent that he overshoots the impact of overcapacity, it is expected that in the next few years, the product price of solar street lighting production and operation industry in China will be slightly oscillated.
2015-2019 China Solar Street Lamp Industry Price Forecast
Solar street light classification:
(1) LVD induction lamp
Green electrodeless lamp with its high luminous efficiency (series light efficiency ≥63Lm/w), high color rendering (≥80), long life (≥50,000 hours), no flicker (every time 2.65MHz), true environmental protection (excluding Liquid mercury) can be started and restarted immediately. It is not afraid of shocks. It can be used as a green rookie in favor of placement. In electrical planning, it accepts active power factor compensation (APFC, n ≥ 0.98), can provide constant voltage power supply under a wide range of power supply voltage fluctuations, and outputs a stable luminous flux.
(2) High pressure sodium lamps for solar street lights
DC 24V (12V) input to the electronic ballast, the output low frequency (or high frequency) to provide light bulbs, high-voltage pulse start lamp is due to the electronic ballast lighting, the lamp life is good, can increase the lamp life of more than 30% ( The premise is that electronic ballasts must have reliable planning and quality. If used with our company's electronic ballasts, it will be good for light bulbs and electrical appliances.
(3) Low pressure sodium lamps for solar street lights
Low-pressure sodium lamps are more commonly used light sources, the same luminous flux and illumination, saving more than 50%. Because the low-pressure sodium lamp's luminous tube is sealed in a high vacuum and coated with an infrared reflective film in the glass shell, its luminous efficiency is not affected by the surrounding ambient temperature, and its radiation spectrum is pure, stable, and has no stray light. Strong fog, coupled with the Far East quality electronic ballasts, so that low-pressure sodium lamps are more easily used in a variety of power conditions, especially suitable for solar street lights, tunnel lighting, and high altitude and other special surrounding areas of the ring. The low-pressure sodium lamp emits 589.0 and 589.6 nm monochromatic yellow light, and its light efficiency is up to 200 lm/w. For 35 W, the total luminous flux is 4600 lm and the light efficiency is 137 lm/w. The light efficiency is highest in low-power electric light source products. . Life is 18,000 hours.
(4) Metal Halide Lamps for Solar Street Lights
The greatest benefit of metal halide lamps is their high luminous efficiency, which is as high as 80 to 90 Lm/W. Since the spectrum of the metal halide lamp is a superimposed linear spectrum at the fundamental level of the continuous spectrum, the color rendering index is particularly high, that is, the color reproducibility is particularly good, reaching 90%. In addition, the metal halide lamp has a high color temperature, which can reach 5000 to 6000K. The dedicated projector lamp can reach 7000 to 8000K (in the case of uniform brightness, the higher the color temperature, the brighter the human eye thinks).
(5) Energy Saving Lamps for Solar Street Lights
Features: Small current, can greatly extend the discharge time of the battery Light efficiency: 40LM/W, Color temperature: 2700K 4000K 64000K Color: White, Red, Green, Blue Life: 6000H Rated voltage: DC12V, DC24V Voltage Category: DC10.8V- - DC14.4V, DC22V-DC28V specifications: 3W, 5W, 7W, 9W, 11W, 13W, 15W, 18W, 20W, 24W, 26W, 30W, 40W, 45W, 65W, etc.
