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:What is the principle of constant current power supply in LED street lamps?
- Constant current drive IC, which is the core component of constant current power supply, utilizes the principle of PWM (wave width control)The power of digital square wave, and then according to the information management of the power supply source from the partyThe duty ratio of the wave thus keeps the output current constant.Field effect transistor or module
- Q:LED good or low frequency electrodeless lamp?
- LED is the light produced by hole migration. Electrodeless lamp is an electromagnetic field to excite gas particles. Judging from the current technology, LED is not mature, so electrodeless lamp is better
- Q:What are the main uses of LED street lamps?
- Street lights must be used on highways, such as roads, highways, urban roads, parks and so on
- Q:How can I get the LED street light?
- Products must be certified in order to export, and if you do not have the right to export, you have to rely on agents, export companies might as well do domestic, I can also do certification agent
- Q:Do you think it is expensive to install LED street lamp with WIFI function?
- The cost will be much higher, and it will involve control and network problems.
- Q:Energy saving control of street lamps can save energy?
- The power consumption of street lighting also weakens the effect of landscape lighting on both sides of the road. Therefore, in accordance with the provisions in the design of "lighting design standard" City Road in luminance, uniformity of illuminance and combining the actual situation of site design, reasonable selection of light source, so as to meet the needs of the road and can meet the demand of average illumination, surface illumination uniformity requirements, maximize the utilization coefficient of lamps, in order to save the purpose of energy.
- 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:What are the benefits of a modular LED street lamp?
- LED modular lamp benefits: first heat better, beads scattered, heat accumulation is relatively small, the heat dissipation requirements will be lower;
- Q:Why do street lights use bat wings to match the light curve?
- Make full use of light. LED light is diffuse type, not only will be the problem of uneven illumination glare.
- Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program
- If there are 20 or so parallel units. Each unit of parallel =0.18x30=5.4KW, 6mm - 10mm - copper or aluminum wire. Light controlled single-phase AC contactor 50A.
