Rural solar street light

As urban rural integration policy since the implementation of road lighting, every street lamp manufacturers rushed to product research and development of all kinds of street lamps, in order to occupy the market a certain position, the current market trend of mainly high lamp is especially significant, at the same time consumers in growing

with the implementation of the integration of urban and rural road lighting related policy, all sorts of street lamp manufacturers have developed all sorts of street lamp products, in order to occupy a certain market position. Currently, give priority to with light, particularly the market trend. At the same time, consumer understanding of light fittings and demand also appeared. Today's version of the key light is briefly introduced one of the main parts: led lamp. Many people used to put the & other high lamp. Called & other led street lamp. 。 Therefore, shaw also and everybody call it together! Led lamp is different from the traditional high pressure sodium lamp, high power leds lamps light source adopts low voltage dc power supply and gallium nitride based power blue light-emitting diodes with yellow phosphor synthesis efficiency white light diode, with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index unique advantages, can be widely used in urban road lighting. Housing can be made of high temperature resistance and resistance to low temperature of 135 degrees 45 degrees of polycarbonate tube.

light emitting diode is a kind of based on the formation of the semiconductor PN junction, gives the weak electrical energy efficient solid-state lighting. In certain forward biased and the electrical flow injection, injection to P OuDeKong cavity in the electronic and injected into N area spreads to the active area after the emitted photons, electrical energy directly into light energy. The advantages of high lamp accessories led lamp: 1. The characteristics of the leds lamps itself & ndash & ndash without diffuse light of one-way and ensure the efficiency of lighting. 2. The present invention has unique secondary optical design, the led street lamp light to the lighting area, further improve the efficiency of lighting, achieve the goal of energy saving. 3. At present, the led light efficiency of the circuit has reached 110 - 130 lumens per watt, empty still has great development, the theoretical value of 250 lumens per watt. However, high pressure sodium lamp luminous efficiency as the only power increases. Therefore, overall led street lamp luminous efficiency higher than that of high pressure sodium lamp ( This kind of integral luminous efficiency is theoretical, the advantages of high power led street light is in fact of more than 250 w high pressure sodium lamp luminous efficiency higher than that of light emitting diode) 。 4. Led street light light color reproducibility is far higher than that of high pressure sodium lamp. High pressure sodium lamp's color rendering index is only about 23, and led street light color rendering index up to more than 75. From the visual and psychological point of view, compared with high pressure sodium lamp, led street light intensity can reduce more than 20% on average ( Reference the rational illumination standard) 。 5. Led street lamp light attenuation is small. Light attenuation is less than 3% within a year, 10 years later still can satisfy the requirement of road lighting. However, attenuation, high pressure sodium lamp has a great deal of attenuation in about a year more than 30%. Therefore, the design using the power of the led street lamp can be lower than that of high pressure sodium lamp. 6. Led street light is equipped with automatic control and energy saving device, in the case of meet the requirements of different times lighting, as far as possible to reduce the power, save power. Spark intelligent led street lamp which can realize computer dimming, time control, lighting control, temperature control, remote control, humanized functions such as automatic detection. 7. Light-emitting diodes (leds) is a kind of low voltage devices. Driving voltage of the individual leds for safety voltage, a light-emitting diode series products to power of 1 watt. Therefore, it is a kind of safer than using high voltage power supply power supply, especially suitable for public places, Such as street lighting, factory lighting, automotive lighting, civilian lighting, etc. ) 。 ) 。
