Scientists Develop Efficient GaN-based Green LEDs
Scientists Develop Efficient GaN-based Green LEDs
A research team led by Shengjun Zhou at Wuhan University has reported developing efficient GaN-based green LEDs on sapphire substrate. They proposed a hybrid nucleation layer consisting of sputtered AlN and mid-temperature GaN components to boost quantum efficiency of GaN-based green LEDs.The team says the hybrid nucleation layer provides a promising approach for the pursuit of efficient III-nitride emitters in the green-to-amber region.Currently, the development of efficient III-nitride emitters in the full visible range is very attractive. The integration of multicolour III-nitride emitters can enable efficient and precise management of the mixing spectra to realize high-resolution displays and various smart lighting applications. However, owing to the poor efficiency of III-nitride emitters in the green-to-amber region, these promising applications have been largely delayed.The researchers have fabricated high-efficiency InGaN/GaN green LEDs on sapphire substrate by using the novel hybrid nucleation layer. A stacking fault band structure was generated at the interface of hybrid nucleation layer and GaN, which facilitated the misfit stress compensation. Benefiting from the early misfit stress relaxation, they achieved reduced dislocation density and residual stress in the green LEDs. An efficiency improvement of ~16 percent was demonstrated in the mass production by using the hybrid nucleation layer. This gain is attributed to the increased localisation depth and spatial overlapping of the electron and hole wave functions.‘Toward efficient long-wavelength III-nitride emitters using a hybrid nucleation layer' by Bin Tang et al, Optics Express, 29(17), 2021 WHU team boost quantum efficiency using hybrid nucleation layer

[Industrial Mine Lamp] Energy Saving and Environmental Protection!
  Author :Green earth– LED Strip Lights manufacturersThe industrial and mine lamp is currently a very important role in lighting, that is, energy saving and environmental protection, it is the primary choice for green lighting. When purchasing LED industrial mine lamps, the LED energy-saving lamp must not be blindly selected, and according to the actual situation and understand the performance of the lamp, it is purchased and then purchased in the future. Mainly in accordance with the following two points:1. The power of the mine lamp: the power determines the brightness and power consumption of the working mine lamp. Since we use energy-saving luminaire, then we can't choose high-power lamps. And choose to match. That is to say, the power of the selected luminaire is just to meet the brightness required to illuminate. We must determine the area, brightness requirements of the lighting before buying, the LED industrial mine lamp, the number of LED energy-saving lamps (if there is no dead angle to illuminate, you need to use multiple places to install the luminaire).2. The quality of the mine lamp: Quality is a problem that needs to be considered. If it is a large lighting place or installed a certain difficult lamp, it is also difficult to buy a quality in quality, and it will not be imagined, and it will also make the company 's unrecognized losses. It is determined whether the quality of the LED and LED energy-saving lamps is strict.If you need the indillant lamp and want to know more about the information about the industrialization lamp information, please feel free to contact our website inquiry!
How to Use a Dimmable Led Light Bulbs: 5 Key Tips You Should Know
How to Use a Dimmable Led Light Bulbs: 5 Key Tips You Should Know
This article explains the "must-have" terms that homeowners or contractors need to know when buying LED products, provides guidelines for choosing products for various indoor environments, and highlights some pitfalls to avoid and be aware of. the transition to LED lighting was a success. There are already more LED products and alternatives available on the market than there have ever been for traditional energy saving incandescent bulbs and compact fluorescent (CFL) bulbs. While some LED products may look like any other fluorescent lamp or lamp, the variety of products, the new terminology introduced by the lighting industry, and the fact that LEDs are a different technology than we have been accustomed to for decades could make the transition. to LED lighting is quite difficult. Before you rush to buy a new set of dimmable LED bulbs, this quick guide will provide you with five useful pieces of information to help you shop with confidence.However, there are some factors to consider before choosing LED bulbs and dimmers. Follow this guide to ensure a smooth darkening process. If, when buying LED lighting, you pay attention to the working components of the dimming and dimming function, you will save yourself extra hassle during installation and will not damage the lamp and dimmer. Installing dimmers with compatible luminaires not only saves energy, but also allows you to dim ambient light that is too bright and better control the atmosphere in the room. Dimmers save energy by reducing the flow of electricity to the light bulb and allowing the light to run at a lower wattage.Because light shines longer under stress, dimmers are known to extend the life of light bulbs. Traditional dimmers work by limiting the amount of electricity supplied to the light bulb. Since they were designed to work with incandescent bulbs, they are not always suitable and can actually interfere with LED performance. A combination of incompatible dimmers and bulbs can result in flickering light, limited dimming range, slow start-up, humming, intermittent lighting, and shortened lamp life.If you will be using LED bulbs, the easiest way to avoid these problems is to make sure you have a compatible or universal dimmer. This is why most manufacturers usually provide a list of compatible dimmers that have been tried, tested and certified for use with their LED bulbs. The first thing to do if you are buying LEDs that you want to use with a dimmer is to make sure you are buying dimmable bulbs. Most manufacturers offer non-dimmable LED bulbs without any built-in dimming hardware, and while they're good, if you're looking to save a dollar or two on a bulb designed for a non-dimmable light, this is the last thing you need. if you want to. like a dim light.The cost of using a light bulb has to be considered, and the beauty of LEDs is that they are not worth the cost at all. In many cases, you will not be able to supply enough LED power to meet this minimum requirement as they use very little power (and fewer watts). Then it is best to switch to a dedicated LED dimmer or 12V light source. For LED bulbs, you must use a dedicated dimmer designed for this type of lighting.If you need the light to turn on or off, you can use a dimmable or non-dimmable lamp. When it comes to 12V LED lights, look for dedicated light sources for your control system, as most of them have an adjustable block. Compact fluorescent and LED lamps. To dim an energy efficient light, first make sure the light itself is dimmed.LEDs offer numerous advantages over traditional incandescent bulbs, last longer and use less power, but standard LEDs do not work with dimmable switches — special dimmable LEDs are required. They are built into the lamp itself (so you can adapt LED lamps directly to existing fixtures without having to reconfigure them) but must be compatible with dimmer components for proper dimming. These are usually LED lamps adapted to dimmers with built-in controllers.If you want to dim the lights, it's best to know the type of switch and bulb you will use. Remember, dimmable LED smart bulbs must never be used with any type of dimmer switch-they cannot work together.With LEDs, the problem is with fast on / off used to dim the lamp, which can cause vibration to the lamp components. A common problem with dimming LEDs is sudden on or off when trying to adjust the light level with the dimmer switch. Using incompatible dimmers may result in flickering or insufficient dimming.Therefore, although Shakur said dimming is the key, LED bulbs can be a bit tricky because it is a different technology from incandescent bulbs. It says that you should buy dimmable LED bulbs, otherwise you may end up seeing flickering lights, which will produce subtle strobe effects when you try to dim them. This is mainly a problem of cheap lamps, and Shakur said there is a simple solution.But LEDs also provide great benefits and provide you with new ways to control room lighting more easily, which will be described in detail later. First, LED bulbs have a much longer lifespan than incandescent bulbs and use less energy to emit the same amount of light. Compared with old-fashioned incandescent bulbs, LEDs can save you more than PS180's lifetime power consumption.For incandescent lamps, there is a generally accepted correlation between watts consumed and brightness produced, but for LEDs, watts do not predict very well how bright a lamp will be. More importantly, 60W equivalent LED bulbs may appear brighter as the light is colder.Use this graph to see the equivalent wattage and luminous flux for older incandescent bulbs and three types of energy saving bulbs (LED, halogen, and CFL). Just match the old lamp caps with the LED versions, taking care to compare the lumens or brightness levels as well (again, a lower lumen lamp may be nicer).These bulbs offer much more reliable performance, but depend on an LED-compatible switch called a down-slope dimmer. The dimmable LED transformer allows dimming of constant voltage LED products and works with most standard dimmers so you may not need to replace your existing dimmer. Unlike traditional lighting such as incandescent bulbs, dimmable LED bulbs do not depend on voltage to determine the level of brightness.For example, if you want to illuminate a work area or an area that requires attention, such as a kitchen counter, dimmable LEDs may not be of much use. So remember, when choosing lighting, whether it is tungsten, fluorescent or LED, in most cases, whether your lighting is really flicker-free or not may not matter.
