FAQ
Q: Whether the LED lights really have 50,000 hours lifespan?
A: 50,000 or longer lifespan is only theory from lab test.But due to working environment are different from
in lab,actual lifespan is only <=30,000hours. Meanwhile it can also be 50,000 hours lifespan if it adopt very good material.
Q: For same power,why different suppliers with different brightness?
A: Different chips,or same chip but different brightness version.The brightness will be different.But for same chip
and same brightness version,the brightness will be slight difference.But please make clear the brightness difference
between LEDs and lamp fixture.
Q:What is colour temperature?A: Kelvin is a way to measure "temperature", the light from LED lights emit a certain color, which we have catagorized
in CTT(kelvin).For example, a warmer (lower color temperature) light is often used in public areas to promote relaxation,
while a cooler (higher color temperature) light is used to enhance concentration in offices.
Q: What is CRI?
A: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.
Q: What is PF and efficiency?
A: PF and efficiency is to feedback the driver electrical performance.
- Q: How many volts is the 42wled solar street light?
- Usually less than 15 watts of courtyard lights are 12 volts, and then small is a few watts of lawn lights, is 3.6 volts.
- Q: The difference between LED modular street lights and LED street lights
- Some common LED lamp beads is all welded on a aluminum plate, the design structure is different not the same name.
- Q: Why is the higher the current, the lower the light efficiency?
- Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
- Q: What role does the light controller and driver play in the LED street light component?
- At present, light emitting diode driver chip can be divided into constant voltage drive chip, constant current drive chip and pulse driver chip. Among them, constant voltage drive chip is generally our most common DC/DC boost chips. The advantage of this scheme is that chips are cheap and do not have complex peripheral circuits. But only constant voltage drive LED will drive the output current of the circuit is uncontrollable. LED brightness consistency cannot be guaranteed.
- Q: How much is the LED terminal voltage of the solar street light controller v?
- This depends on the situation, LED, the general is 5V
- Q: Street lights and signal circuit connections
- LED street light color light than many high-pressure sodium lamp, high-pressure sodium lamp color index is only 23 enterprise directory, while the LED lamp more than 75 of the color index, take into account the psychological point seems to be visually reachedThe same brightness, lighting LED lamp, can be reduced by an average of 20% or more, than high pressure sodium (refer to inluReasonable lighting standard); page 5, LED street light a small decline, a year decline was less than 3%. 10 years still reached the road soHotel and illuminance requirements, while the high pressure sodium lamp big drop, about a year has dropped by more than 30%, so, LEDStreet use power can be lower than that of high-pressure sodium lamp designs; page 6, LED streetlights energy-saving automatic control devices can be achieved in time to meet the situationLighting conditions, as far as possible to reduce the requirement of different maximum power saving energy; Guangyuan Wang Technology Co. Ltd.
- Q: Who knows the relationship between the number and weight of LED street lamp
- The relationship between the number of LED light weight and beads, the strength of your life,Can not get a formula, a single lamp can be 1W, or 100WThe relation between street light weight and street lamp power can still be obtained, only at presentDie casting space aluminum cooling, about 100W, about 20 pounds
- Q: How much solar panels do you need to make a 15W LED solar street lamp?
- Here we give our solar power street lights (or systems) calculation method, I hope useful to you. 1. solar panels power (electric power = W) * every time the lights (H), average sunshine time * peak loss coefficient (2) = 2. of battery capacity with electrical power (W) every time the lights * H / {system voltage (12V or 24V)} * (rainy days +1) * loss coefficient (1.75)
- Q: Does the LED street lamp need lightning protection?
- Need to install power supply lightning protection, also known as surge protector
- Q: Is the power LED lamp constantly flashing? Is it a power supply problem?
- If the driver has over temperature protection function, and material performance can not meet the requirements of heat lamps, driving over temperature protection work will have a flash out of the phenomenon, such as: 20W cast light lamp shell used to assemble the 30W, it will not do heat.
