Why Newey LED lights?

Basic principle of a LED (Light Emitting Diode)

A light emitting diode consists of multiple layers of semi-conducting material. When the diode is being used with direct current, light is produced in the active layer. The light produced is decoupled directly or by reflections. In contrast to incandescent reflector lamps, which emit a continuous spectrum, an LED emits light in a particular color. The light's color depends on the semiconductor material used. Two material systems are mainly used, in order to produce LEDs with a high degree of brightness in all colors from blue to red and, by means of luminescence conversion, also in white. Different voltages are necessary, to operate the diode in forward bias.

LEDs are semiconductor crystals. Depending on the composition of the crystal compounds, they emit light in the colors of red, green, yellow or blue, when current flows through them. With the help of an additional yellowish fluorescent layer, blue LEDs also produce white light (luminescence conversion). Another method of producing white light consists in mixing red, green and blue light-emitting diodes (RGB). This is used particularly where the priority is not general white lighting but rather decorative effects with various rich colors. With the three RGB colors, any number of color tones may be mixed by varying the proportions of the individual colors. In this way, the LED lighting can create fascinating worlds of experience.

Advantages of LED technology

LEDs offer numerous advantages over other lighting technologies. Professional users and home consumers profit to the same extent from limitless design possibilities based on a variety of color, compact dimensions and flexibility of the LED modules. On the basis of the low energy consumption, long lifetime and greater service intervals, high economic benefits are produced. In addition, individual LEDs provide maximum reliability even in difficult environmental conditions.

Reasons why you should be using LED light bulbs

• Because they require less energy to power, LEDS will save you electricity
• Compared to incandescent bulbs, LED lights will save you around 80% of electrical power
• In comparison with a halogen lamp, there is a 75% saving on electricity
• They contain no hazardous solids, liquids or gases – which can be harmful to the environment
• Used as automobile lighting, LEDs have been proven to help reduce the risk of car accidents in daylight hours by 15%
• Because they produce a cold light, LEDs can be ideal for plant growth
• LED Lights are available in a number of different colours and shades that can define the style, setting and ambience you desire
• There is no high-powered discharge that can have a detrimental effect on the eyes
• LEDs use direct light meaning there is no light pollution
• Used as a temperature gauge, LEDs can help you distinguish between hot and cold water
• LEDs have no UV light, eradicating the possibility of skin damage
• Used by your local council as lighting solutions, they will vastly improve the visibility on your roads 
• Despite being cold to touch, LEDs offer a “warm” glow – much like their incandescent counterparts
• They are easy to install – simply screw on
• They are easy to uninstall (yes, that’s a separate reason!) – and won’t burn you
• There is no need for excessive maintenance – once they’re installed, they won’t bother you!
• LEDs have a thick epoxy which makes them incredibly durable and pretty much impossible to break
• LED string lights have thicker wires – meaning they are less likely to get into a knotted mess
• Using LEDs in the outdoors? They are completely rust-proof
• LED Lights don’t flicker
• They have the ability to be dimmed
• LEDs retain their true colours
• They let you walk your dog in the dark (useful, right?)
• LEDs don’t attract bugs and insects
• They are silent and produce no annoying and distracting humming noises
• While typically more expensive than a standard bulb, they are still very affordable and freely available
• They save you money on your electricity bills
• They can last up to 50,000 hours (that’s a long time)
• LEDs last 2400% longer than regular halogen bulbs – which can be in advance of 40 years difference based on average use
• They can help you build a light saber (and who wouldn’t want to do that?)
• LEDs can be installed and utilized both inside and outside of the home with no affect on lighting quality
• LEDs immediately switch-on with no warm-up time
• The lights are fully operational in all types of weather conditions
• They contain no harmful environmental pollutants like lead or mercury
• They are recyclable
• LEDs don’t emit Radio Frequency interference
• They could help improve your eyesight in the future (ok, perhaps a little farfetched)
• LEDs can help to save lives
• The low voltage power supply associated to LEDs increases electrical safety
• They are lightweight
• They are much brighter than your traditional lighting solution and will improve visibility
• They are more flexible, versatile and adaptable than traditional lighting
• Used at Christmas time, LEDs can reduce a risk of a fire compared to standard Christmas lights
• LED Light therapy has been known to alleviate a range of skin conditions
• LEDs do not burn out like incandescent bulbs – their brightness slowly fades
• As a homeowner, you will enjoy the convenience of not having to change a light bulb on a regular basis
• You will save a projected cash outlay on purchasing a greater regularity of traditional lighting solutions
• Most LEDs come with a two-year warranty – compared to a one-year warranty of standard lights
• Because they are environmentally friendly, they lower your carbon footprint
• Using LEDs will make you feel good! (You know, because you’re helping save the planet and all that?)

Comparing the features of Incandescent, CFL and LED bulbs

What is colour rendering index (CRI) ?

An object looks whitish under the fluorescent lamp and meanwhile, the same object looks yellowish under the incandescent lamp. The same object looks different in(or under) different light source. You can see how light source change the color of objects by comparing under fluorescent lamp,incandescent lamp,daylight and etc. Color Rendering is the property of the light source that effects the color of the object. Color Rendering Index(CRI) is a numerical representation to evaluate the Color Rendering Properties of the light source. CRI shows how accurately sample light source reproduces an object color compare to the reference light source.The CRI value of 100 means the sample light source reproduces the same color as the reference light source does.Therefore the higher the value of CRI, the more it resembles to the reference light source. When evaluating CRI, the reference light source is chosen to have the same(or within the range of 5 mireds) correlated color temperature as the sample light source.

Reference light source:

1. Lower than 5,000 Kevin: Planckian radiator

2. 5,000 Kevin and higher: CIE daylight.
