Common questions we will ask;
From typical recessed ceiling LED downlights, surface mounted LED downlights, Spotlight, Magnetic circular LED downlights, LED lighting on a plate, LED bulbs in a holder, Panel LED lights and so on... The list is almost never-ending. It is no wonder many people are easily confuse with what kind of lights to chose from for homes. In my opinion, it is really crazy for there to be so many endless designs just to serve a very generic purpose and location at home. Despite our experience as a prominent lighting consultant, we not going to be technical in anyway with this sharing. We will share how we chose our lights being a consumer ourselves. Steps to chose LED downlights for your home; 1. Be self-aware of your own character. Are you more functional, brand conscious, people conscious, creative, etc… Usually most people are either more of function or more on creative. - It is a waste of time to try and expose yourself to designer lightings but you are a highly functional individual. 2. Chose the shape you prefer (square or round) - Don’t really care the design first. They can be superfluous and unworthy of your good time in examining the slight differences at this stage. 3. Is your ceiling bare concrete ceiling or false plaster/wood ceiling? Look for lights that is meant for that particular category. - The former will relate to surface mounted lights and the latter relates to recessed ceiling. 4. Being realistic about your budget, typical spending habits and the inner desire of wanting to be creative. Assuming you have thought through your step 1 deep enough, often the product you are getting will also fit nicely with you budget. To put an example to the above: A highly functional person may not care for being as creative if it requires spending a lot of money. Knowing this will help one focus on getting the right lighting which he/she may feel comfortable even before buying the necessary. Further, the selected lighting product may just as well complement the design of his home, which I assume had also gone though the same person’s thinking process, in many ways.

Why do you need a professional LED lighting technology specialist these days? 1. Too many products with similar lighting specifications from different suppliers for review. 2. Compatibility issues with lighting hardware and design 3. Integration and implementation issues 4. Design and balancing with the environment 5. Understanding the risks and possible areas of failure (This is a costly and time consuming activity that most contractors usually are not capable to handle.) 6. Trial and error for the implementation due to uniqueness of each project. 7. Get a lighting consultant on board your project early to minimise risk of failuregoing forward. Notwithstanding the above, unless the client is willing to pay a high amount of cost for an undetermined result; it is better to pay a good amount of professional fee to achieve a suitable level of assurance on the success of each lighting project. Of course, paying all this fee doesn't necessarily mean it will be successful. The whole team as stake holders should be realistic that all projects are unique. Many thanks. http://www.illuminatingasia.com/singapore-garden-festival-2016---mystical-depths.html
There are a few commonly used dimming terms in the lighting industry (i.e DALI, DMX, 0-10v, PWM, etc...) Today we share our knowledge on Pulse Width Modulation ('PWM') dimming for LED lighting hardware and products.
LED panel light Led panel lights are becoming the most popular led lights in the interior lighting design while the Led lighting technology is developing. Components of the LED panel light:
1. LED Panel Light Body Frame LED panel light body frame is used for covering the edge of the light. The frame provides the inner protection and thermal conductivity. Aluminium is the common material used for the frame. The advantages of the aluminium are the good heat dissipation and sleek outlook. Nowadays, the PVC is the new material which is introduced into the market. Compared with aluminium, PVC made-up frame is more excellent on security and poorer on heat conductivity. 2. LED Panel Light Light Source. LED 2835 is widely applied in LED panel light because of the advantages of high luminous output and lower cost. Different quality of LED chipset and efficacy plays a big part in brightness, power consumption and lighting quality. 3. LED Panel Light Guide Plate Light guide plate is the important component for LED panel light. Low quality LED panel lights will have non-uniformity of light and dark spots while it is operating. Understanding the types of plastic and refractive index is key to having a better LED panel light. 4. LED Panel Light Diffuser LED panel light diffuser directly affects the light output. Panel light diffuser is made from PMMA or PC. PMMA-made diffuser is high on efficacy---92%. PC-made diffuser is excellent on oxidation resistance. PMMA is considerably used currently in the market. 5. Reflective Plate Reflector It is applied to improve light efficacy to achieve the high brightness. It is made from translucent nanoscale material, its reflective rate could reach 92%. 6. LED Panel Light Power Supply Nowadays, LED panel light with LED driver system is commonly acknowledged in the market. The drivers could regulate the voltage and current from the main power supply to light up the lights. The use of high quality driver directly affects the lifespan of the LED panel light. 7. Installation Accessories Suspension wire, mounting bracket, screws,etc. are also used in LED panel light installation. A great LED panel light should be equipped with all the good quality components, such like the body frame, LED chips, diffuser, reflector, drivers and also the accessories. Thereafter, it all goes into understanding the standard assembling and manufacturing process of the LED panel light. Article by Mr Luo Tianhan (Temasek Poly Year 3 Clean Technology student, 2017) ANALOG VS DIGITAL LED STRIP There are two basic kinds of LED strips, Analog and Digital. They are controlled differently. ANALOG LED STRIP Analog strips come in mono (one color) or RGB (full color spectrum). They can be cut into small segments. The segments are marked by metal contact pads and sometimes have a scissors icon screen printed right on them For each segment the LEDs are wired in series, which means the operating voltages are added up, giving the higher voltage needed. All the segments are wired in parallel, so they get all get the same amount of voltage all the way down the strip, but the current draw adds up depending on the length of the strip. All the LEDs on the strip will act as one, they are non-addressable. One way to tell by sight is that they do not have any driver chips that you can see on the strip (that would be digital!) DIGITAL LED STRIP Digital strips come with RGB LEDs and have a driver chip on the strip that control the LEDs individually. These are also called individually addressable or just addressable. They also come in segmented, where they can be cut down to bite-size lengths. These strips take 5 volts, so they can run straight off a microcontroller. They will power up when attached to 3.3 volts, just not as bright. Addressable LED strips are usually controlled using micro controller to program cool patterns and make them reactive to sensors and switches. Most of the work is in the software. In addition, Digital strips get their information from one data-in pin or two data-in and clock-in pins, dependent of what strip is used. The datasheet for the pinout diagram, voltage ratings and other useful information varies according to the type and the brand. Article by Ms Jesslyn (Temasek Poly Year 3 Electronics student, 2017)
Maintaining colour consistency in LED lightings and light source has always been a challenge. It seems strange that we cannot maintain consistent lighting color tone for a machine made hardware. After producing the LED chipsets, they are stored or group together in different bin. Each bin can be sorted by different methods, one being how close they are of the same colour tone. With the variable nature of the colour produced by white light LEDs, one commonly used metric for expressing the extent of the colour difference within a batch (or bin) or LEDs is the number of SDCM (MacAdam) ellipses steps in the CIE colour space that the LEDs fall into. In this situation as a manufacturer and LED Lighting OEM specialist, we can minimise inconsistent LED lighting colour tone by relying on SDCM (Standard deviation colour matching) or MacAdam Ellipse when selecting the LED chipset to be used in our lighting products. If the chromaticity coordinates of a set of LEDs all fall within 1 SDCM (or a “1-step MacAdam ellipse”), most people would fail to see any difference in colour. If the colour variation is such that the variation in chromaticity extends to a zone that is twice as big (2 SDCM or a 2-step MacAdam ellipse), you will start to see some colour difference. A 2-step MacAdam ellipse is better than a 3-step zone, and so on. References:
http://www.photometrictesting.co.uk/File/blog_LED_colour_difference.ph Through our extensive research and trials on different optical lens, we'd like to share the different lighting effects shown above.
By adopting the right lens type, we can alter a typical mass market LED lighting to fit all environment and scenario. This will allow museums and mid-high end retailers to purchase the same lighting in bulk and adjust the lighting accordingly to fit your display. Inevitably, this may reduce maintenance cost since workers can easily be trained to work with 1 type of LED lighting. The facility owners can also keep a simpler ranger of replacement components, thus saving on holding costs. No matter how good is the interior decor, things will be different without the right lighting. Do contact us if you wish to learn more about how different lighting effects can be affordably achieved through appreciating the available hardware in the lighting industry. Glad to share our experiences in our past public and private establishment projects. Some LED Track lights that we sell has rotatable lens. This allow one to easily change the beam angle and flare size to suit different display with the same LED track lighting. Combine with our 0 - 100% dimming capability embedded within the LED Track light; you would have gotten the most perfect lighting in different senarios with the same tracklight. This makes it efficient and hassle free in selecting what LED track lights to buy. LED lighting has become the preferred choice of lighting for any environment. The rapid development of LED lighting technology and great reduction in prices has often made it the first consideration for any projects.
The question we are working hard is always how to integrated and apply LED lighting suitably in each and every different environment. Today, we touch on the importance of optics in any LED lighting luminaire. Based on our experience, Asian countries (JAPAN, KOREA, TAIWAN, CHINA) mostly focus on LED light source and in the semi conductor production. It is the European countries that focus on the optics. Through the following, we can alter any light source easily; 1. Different thickness of the optic 2. Having lens within lens (Multiple layer of optics) 3. Convex or Concave fundamental 4. The polarising effects from lens 5. Shape of the optics Surely it cannot be one size fits all if the end user is particular how the light source will have an impact on the items displayed. All the above changes the intensity and direction of lights. This will cause differing types of light entering our eyes giving a different perception to how things look. Do contact us to find out more and to have a first hand factory tour for a demonstration on how optics affect the lighting on objects. We'll be glad to share more then! |
