Office lighting simulation- Lighting solutions


Use lamp is in order that it can emit light onto the objects reach some lux level to meet our demand. Such as according to EN standard, work-plane needs to reach 500lux for meeting room. Then question is how many pcs lamp required? What kind of lamp? Say professionally, need what kind of lamp with what kind of light distribution? Need the lamp with how many flux?Firstly we need to consider about energy saving. Secondly we need to concern if cost is reasonable. Last is to make layout scientific and professional.Energy saving: we need to know about the light efficacy, lm/wCost: Use the least quantity lamps to reach office lighting standardLayout: Several lamps can be selected and combine together to reach different layout and meet our need. It needs professional design software Dialux evo to design professionally. It can calculate very accurately illuminance result and show to our customer. Helps customer to know what kind of lighting solution is he needed. It brings a lot of benefits to your business and improve customerís satisfaction.Example of office lighting optical simulation data, false color chart, isolux diagram, data table,etc.Maybe youíre project contractor or youíre the person in charge of some project. You donít know much about these knowledge. It doesnít matter I can provide free service to provide reasonable lighting solution and professional advice.

How to Choose the Right Supplier for Solar LED Street Lights??


As solar Led street lights are environmently friend and energy saving, common people and government like to use it. For the good future, a lot of factories come into this industry.Mainly there are three groups:1) Solar panel factories and suppliers. As these suppliers are professional and familiar with solar panel manufacturing and whole system accessories. 2) LED lighting manufacturers3) New comersWe recommend several standards for finding the right suppliers for solar LED street lights1) Samples quality is the first test way. Suppose several samples test cannot pass, I think you will lose confidence in the factory or suppliers.2) Complete manufacturing in LED street lights and solar panel/ quality control procedure/ sales manís communication and skills3) Lighting design solutions for your project. Suppose drawing is professional and reasonable, you can have a test on samples.4) After trial orders, you maybe will meet one or several quality issues. Their feedbacks and attitudes for defect products can help you distinguish.

Solar LED Street Lightingís disadvantage?


In previous text, we have seen a lot of advantages of solar LED street lighting, but it still has some disadvantages:1) As we all know, solar LED street lights are composed by LED street head/pole/solar panel/solar controller/solar battery pack.For raw materials purchase, its first input rate is much more than normal LED street lights or traditional lights. 2) As different zones have different sunlight times and winter temperatures, it needs engineer to design the suitable solar panel power and battery capacity.Good match will be effective and money saving or it wonít be lighting on.3) The dust on solar panel will reduce the efficiency of solar panel and maintenance will be not easy4) According to installed city such as Beijing, all solar LED street lights are removable after one year time use. It makes people worry about warranty of solar LED street light.

Why Solar LED Street Lights?


From Alibaba led street lights inquiries, we can see a lot of businessmen especially from African/Egypt whose basic electricity systems are weak or no electricity districts are eager to seek the solar led street light factories or companies.LED street lighting is common in led outdoor lights but it is a bit special while adding solar factor. Solar was very popular topic in previous time. LED is popular in recent time.Now two factors are combined together: solar LED street lights.Comparing with normal LED street lighting, solar LED street lights will have more accessories: solar panel/inverter/battery pack. The advantage is obvious:1) Country or community doesnít need to invest money and labor into electricity system in road. It can bring benefits in public budget saving.2) Led light source is energy saving and solar Led street light will be more energy saving and friendly for environment.3) Solar Led street lighting is DC current and low voltage which is safer.4) No need to pay for electricity fee after installation.5) Installation service is cheaper. Donít need to dig and install electricity wire.

Differences Between COB &SMD LED floodlight(1/2)


On 2014 HK lighting fair, one buyer asked me a question: now, SMD LED flood lights are popular in the market and what is difference between COB LED flood lights and SMD LED flood lights?I think this puzzle is also common in other clients who's importing LED floodlights from China mainland. Letís have a look about the differences:1) LED chip sealing ways are different: COB(Chip On Board) LED flood lights chip is composed by many small size LED chips firstly and totally is sealed together with glue. Normally there are two shapes: one is round and the other is square: VSFinished COB LED flood lights will be like below: VS SMD(surface Mounted Devices) LED flood lights is composed by many independent LED chips and they will be in several lines not concentrated finally by glue. Only one shape: square The finished SMD LED flood lights is as below: The entry was posted in Sunflowerlite and tagged LED floodlights /SMD LED flood lights /COB LED flood lights on 16 Nov,2014 by Sunflower.

Differences Between COB &SMD LED floodlight(2/2)


2) Lighting beam angle is different:COB LED floodlight lighting beam angle is obviously more concentrated.SMD LED floodlight lighting beam angle is bigger than COBís3)The lighting distance is different:COB LED flood light is straight and more far than SMDíS4)Lighting effect is different:COB LED flood light makes lighting effect focus on building some cores so that let it outstanding. SMD LED flood light is approaching candle lighting. It is one core lighting different directions. It enlarges lighting effect rang.5)Brightness is different:COB LED flood light brightness is higher than SMD LED flood light.6)Price is different:As COB LED flood light is more popular firstly than SMDís, mass purchase and production make the raw material cost down.Meanwhile SMD LED floodlight labor cost is higher than COB.Finally it leads to a result: COB LED flood light is much cheaper than SMD LED flood light. So price also holds back SMD led flood light's development. The entry was posted in Sunflowerlite and tagged COB LED flood light/ SMD LED flood light on 16 Nov,2014 by Sunflower.
