4 tips for buying a led street light

Led street light mainly used in the urban expressway, trunk road, secondary road, slip road,factories, schools, gardens, residential quarters, city squares, gardens and other road lighting. Howto choose a led street light is more and more important to a lot of people. Following are 4 tipswhich show you how to buy a led street light.

Take the Led street light 50w for reference.1. Luminous efficiencyLED lighting technology matures, the power LED light source is required to meet the generalstreet light flux. General high pressure sodium lamp luminous flux is 100LM / W, is commonlyused in high-power LED 50-60LM / W, with the best LED chip abroad can reach 80LM / W,luminous efficiency is higher, which means better energy efficiency, which is Select the Led streetlight of the most important indicators. However, LED's standards this has not been clearly defined,so when purchasing Led street light must be carefully confirmed.

2. LED street light failureNow some businesses, in order to reduce costs, on the use of hundreds of small 0.5W power LED.However, this low-power LED light failure is very serious, the light fades to 80% of the life ofonly 1000 hours. So, as long-term use of the street needs is absolutely not allowed to use suchsmall power LED, the choice of powerful LED (30W or more generally refers to), it would bemuch better light fades.

3. Led street light weight problemLed street light due to technical content, complex composition and other reasons, some of thehigh-power lamp will far exceed the weight of ordinary high-pressure sodium, so thecorresponding support material requirements more higher. However, some manufacturers haveLed street light LED lamp as much as possible to reduce the weight from the original single lampabout 30 kilograms, down more than 10 kg, weight reduction there is further downward trend.

4. Led street light heatBecause LED is a semiconductor components, and its chips affected by the temperature decreasedto 30% of the initial luminous flux, illumination will lose significance, that is the end of life, intheory, high power LED street life of 3-5 million hours, but which is an important prerequisite forgood heat dissipation. It is worth mentioning that the country has adopted the world's leadingmanufacturers of needle cooling technology.>> More led lights information
