FAQ

Q: Nearly all high lumen led street light are the same exterior,how to tell quality?

A: Price and exterior.

Due to raw material cost difference is big,poor quality are all poor housing exterior with short FINs and light weight. So prices are also low. Besides,the driver exterior is also low-end with poor IC,MOS and capacitances.

Q: Does really have 50,000 hours lifespan

A: 50,000 or longer lifespan is only theroy from lab test.Actual lifespan is only <=30,000hours.< span="">

Q:For same power,why different suppliers with different brightness?

A:Please make clear the LEDs brightness ≠ lamp fixture brightness.

For example,50W LED flood light,bridgelux 110-120lm/w LEDs,the LEDs brightness will be 5500-6000lm.But the LED flood fixture will be only around 4100lm.

Q: What is CRI?

A: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.Generally,LED flood and LED high bays,if they are made by epistar or bridgelux chip,the CRI are all around 70-75Ra.If this figure higher than 75,please ask your suppliers to send test data.

Q: What is PF and efficiency?

A: PF and efficiency is to feedback the driver electrical performance.Higher PF and efficiency with higher cost

Q: What is the difference between Epistar and Bridgelux chip?

A: Epistar is Taiwan brand, Bridgelux is USA brand. Both brands are very good quality.

Epistar 90-100lm/w version usually for mid-end market with very stable quality, And Bridgelux 110-130 lm/w version usually for high-end market.

Q: Is there cheap shipping cost to import to our country?

A: For small order, express will be the best. And for bulk order, sea ship way will be better but take much time.

For urgent orders, we suggest via air to airport plus our ship partner send to your door.

Q: How many volts is the wind power streetlight led?: The difference between LED street lamp and conventional high-pressure sodium lamp street lamp is that the light source of high-power LED street lamp adopts low voltage direct current power supply and high efficiency white light diode synthesized by GaN based power blue LED and yellow phosphor

Q: How to calculate the number of Duodawa with LED lights: Road lighting requirements: mainly including illumination requirements, illumination uniformity requirements of two kinds.Uniformity is generally over 0.3, the greater the uniformity, indicating that the street lights, walking more open, lighting effect is better.Illumination is related to power and installation height of luminaire. For the street lamp, we hope that the greater the angle of light, the better evenness can be achieved, and that the distance between the lamp posts can be widened, the number of the lamp posts can be reduced, and the cost can be saved.

Q: Does the LED street lamp need a starter?: LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.

Q: What are the parts of a LED street lamp?: Solar energy is one of the most direct the most clean energy, solar energy is a huge amount of renewable energy, each day to reach the earth's surface radiation can be approximately equal to 2.5 millions of barrels of oil, can be said to be inexhaustible. The LED spectra of almost all concentrated in the visible light spectrum, so high luminous efficiency, is generally believed that energy-saving lamp energy-saving 4/5 is a great initiative, but also energy-saving energy-saving lamp LED than 1/4, this is a great reform of solid light source. Solar LED lighting integrates the advantages of solar energy and LED.

Q: What role does the light controller and driver play in the LED street light component?: Constant current drive chip solves the problem of uncontrollable current before constant voltage drive. At present, the constant current chip can achieve constant current accuracy of about 1%, and has a simple peripheral control interface, which can flexibly set the required output current, so it is very popular. But these chips are much more expensive than constant chips, and peripheral circuits are complex. At the same time, because of the constant output current, the whole chip will discharge faster when the battery is used as power supply.

Q: How much is the LED street lamp?: Should not be cheap, power 200W or so, the main driver expensive

Q: What heat sink is best for LED street lamp radiator?: Is natural heat dissipation, what is called natural heat dissipation, that is, rely on the lamp's own radiator to dissipate heat, and now most of the market is fin type heat sink, this advantage lies in the cost point, passive heat dissipation time. However, the disadvantage is that the heat dissipation is very slow, far less than the high-power heat dissipation requirements. Good service life is less than 2 years. But recently, the market has a kind of through-hole type heat radiation lamp, break the traditional heat dissipation concept, increased the heat dissipation surface, let the air form convection. The cooling effect is remarkable. You should be interested in discussing LED lighting technology, so you can leave a contact. I'm technical. Hope to be adopted

Q: Compared with LED street lights, what are the advantages of graphene street lamps?: The highlight of graphene is energy saving. Graphene because of the heat conductivity and better performance, compared to the ordinary LED Lantern Festival, a lot of heat dissipation area, so LED lamps can save energy by 20% to 30%;

Q: What is the difference between solar LED street lamp and ordinary energy-saving street lamp?: 1. from the purchase and installation cost, LED solar street as general lights are more expensive, but without the solar street lamp cable as set up, just dig a hole and the embedded parts, battery, lamp base buried secure can, so many cable and labor costs, in fact, the price difference between divergent and general lighting.2., from the use of the role of view, LED solar street lamps using the latest LED light plate, lighting effect is generally more than 2 times the energy-saving lamps, and more energy saving role, self-sufficiency in the form of power supply is also unmatched by general street lamps.3., from the quality and after-sales point of view, LED solar street lamps choose hot galvanizing and other high-tech skills, the use of data is much higher than the general quality of street lamp poles. Today, the LED solar street lighting industry is in high-speed development period, many solar street lighting manufacturers after-sales service is also close to, as if the perfect situation.

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.
