Beijing music company D street lamp instead of high pressure sodium lamp used for solar street lamps

First of all, is the so-called; Luminous efficiency; Problem, under the condition of current technology, the LED luminous efficiency is not high pressure sodium lamp, this is an indisputable fact, but high pressure sodium lamp spectrum of concentrated in the yellow area, its colour temperature is low, only 2000 - 2500 k, and

the first is the so-called; Luminous efficiency; Problem is that under the condition of current technology, light emitting diode lamp luminous efficiency is lower than that of high pressure sodium lamp, it is indisputable fact. But high pressure sodium lamp spectrum is concentrated in the yellow area, colour temperature is relatively low, only 2000 - 2500 k, and relatively high color temperature, such as light-emitting diode led street lamp of the temperature of 4000 - neutral white Temperature of 5000-5000 k, cold white 8000K。 At the same time, compared with high pressure sodium lamp, led lamp color rendering index higher, in the actual lighting close to natural light, the second is: irradiation uniformity; The problem is that although leds lamp light is relatively concentrated, but its light path of the two design can make the lamp light source presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so as to realize the uniformity of illumination. There is. Light attenuation; Problem is in the process of practical application, due to long-term high temperature working environment, can affect the service life of led lamp. Under the condition of current technology, virtually impossible in a short time, improve the efficiency of light-emitting diodes lamp luminous, so only by strengthening the cooling to prolong the service life of led lamp. Shandong solar technology development co. , LTD. Is located in; Home of China street light; Shandong, shandong.
