How to adjust the lighting time solar street lamps

Led lights do not work are likely to be driven damaged. Led street lamp only light pole and led lamp holder, simple structure, in general it is not easy to appear problem. But meet the Led street lamp is not lit, a lot of people think is lamp bead is broken? Shandong led street lamp manufacturers



the led street light does not work is likely to be driven damaged. Led lights' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Only a light pole and led lamp holder, simple structure, in general it is not easy to appear problem. But meet the Led street lamp is not lit, a lot of people think is lamp bead is broken? Shandong led street lamp manufacturers remind you are likely to be driven to damaged?

so what reasons can lead to damage of led street lamp driver, and what are we to do? After drive damage, shandong led street lamp manufacturers small make up to discuss with you.

in the first place, it is possible that buying led street lamp head 【 LED street lamp head namely semiconductor lighting, light emitting diode as light source, because it is a kind of solid cold light source, green pollution-free, less consumption, high luminous efficiency, long service life, etc. 】 Poor quality, the use of inferior drive, coupled with the led street lamp head is problematic if the cooling performance is bad. Everyone in the choose how many money to buy the led street light lamp head as far as possible choose normal manufacturer integrated heat lamp holder, conditions permitting, coating on the surface of the shell in contact with the lamp shell heat conduction glue' Thermal conductive adhesive is a one-component, heat conduction model, room temperature curing silicone adhesive sealant. 】 Or stick a thermal pad' Thermal pad is high performance gap filling thermal conductive materials, mainly used in electronic equipment and heat sink or product transfer interface between the shell. 】 , improve the cooling performance of the drive, so as to guarantee the reliability and life expectancy of the drive.

second, is don't understand the working characteristic of LED, some customers require the input power of lamps and lanterns is a fixed value, fixed 5% error, only for outdoor lights LED lights to regulate the output current to achieve specified power. Due to different working environment temperature, time and the light is different, each a lamp power could have bigger difference. Volt-ampere characteristics of leds, however, decided the LED driver for the constant current source, the output voltage changes over the LED load series voltage Vo, the drive efficiency of the whole machine almost the same, the power input change with Vo.

so, LED driver, users in the proposed requirements, should first understand the LED lighting' 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 Street lamp operating characteristics, to avoid some do not conform to the operating characteristics of the principle of index, at the same time avoid far exceeds the actual demand indicators, to avoid excess quality and cost and waste.

in addition, the led street light drives due to the power grid load rejection and lightning induction, into the various surge from the grid system and some surge can cause the damage of the led.

the Led street light does not work is likely to be driven damaged. Shandong led street lamp manufacturer to remind you if you have the led street light is not bright, or a few light bead is not on, is likely to be driven damaged. Can contact the manufacturer to troubleshoot, replace the new driver.
