Q : The common problems in LED Industry 2013-01-21
A :

LED color difference

Basically there is no color issue in the single LED applications, but the color issues many be obvious when the multiple LEDs are put into use at the same time. Firstly, take a look at a group of lamps and check whether the lights colors are inconsistent, then the quality of the  led lighting is not in the high level.

LED insulation
The insulation refers to the heat dissipation substrate to the positive and negative of the LED, and this is the fundamental problem which is unresolved currently, only taking use of the remedial measures, such as taking use of the aluminum substrate to deal with insulation (the initial aluminum plate is not insulated, and now almost all do) and we may find incomprehensible. The single insulated LED has little effect while a large number of LEDs in series are affecting a lot.

LED light-emitting angle
Due to the LED lens package of various manufacturers are not the same, even the same emitting angle (nominal angle), the effect is not the same, making the selection of poly mask even more difficult, and still not universal.

LED brightness is insufficient
The insufficient brightness makes the LED light can only play a supporting role in the lighting industry, and is mainly used for decoration.

LED heat problem
In theory, the LED does not give out too much heat, but due to the immaturity of the technology, the LED is well-known for its heating.

LED efficiency is low (light emitting rate)
At present, the LED electric conversion efficiency is too low (because there is no device to test, and the detail information has not been given).

LED light fades and life
The light fades and life of LED produced by the Mainland or Taiwanese is more serious, the matching of LED driver may affect the light fades and life of LED.

Benefits of LED lights

 

The main benefits of LED lights are their energy efficiency and lifespan.

 

LED lights:

 

  • Use about 85% less energy than halogen or incandescent lights
  • Use about 5% less energy than CLFs LIGHTS
  • Save you money on your power bills!
  • Have a long lifespan – between 30,000-50,000 hours depending on the globe
  • Reach full brightness instantly
  • Contain no mercury or lead
  • Emit no UV rays or infrared radiation
  • Operate at a much cooler temperature, making them a safer option than halogens

 

Because LED lights use approximately 85% less energy than halogens and incandescent lights, as well as doing your bit for the environment you’ll also be saving on your power bills. In addition, LED lights last significantly longer than halogens (1,000-5,000 hours approx.) and old incandescent globes (1,000 hours approx.).

 

Depending on the globe, LED lights can last between 30,000-50,000 hours, meaning that although LED lights are more expensive to purchase initially, on top of power bill savings, you won’t have to replace the globes nearly as often, making them more cost effective in the long run.

 

LED lights are about 5% more energy efficient than CFLs, another form of energy saving lighting, however the main advantage of LED lights over CFLs is lifespan. CFLs are estimated to last between 8,000-15,000 hours, while LED lights are estimated to last between 30,000-50,000 hours (depending on the globe).

Q : What is LED lighting? 2012-10-18
A :

What is LED lighting?

 

LED lights are the latest technology in energy efficient lighting. LED stands for ‘Light Emitting Diode’, a semiconductor device that converts electricity into light.

 

LED lights are super energy efficient, using approximately 85% less energy than halogen or incandescent lighting – meaning significant savings on your power bills. LED lights also have a much longer lifespan than other types of lighting - see the table below.

 

Lighting technologyEstimated lifespan*
LED30,000-50,000 hours
CFL8,000-15,000 hours
Halogen1,000-5,000 hours
Incandescent1,000 hours

*Depending on the globe

 

What are the other types of lighting?

 

Incandescent

Incandescent globes look like the traditional ‘Edison’-shaped light bulb, with a filament strung across two metal bars in the centre of the globe.

Due to government regulations, as of November 2009 you are no longer able to purchase standard incandescent globes. These globes were extremely inefficient because they only converted 5-10% of the energy they produced into light, while the remainder was converted to heat. The result was an extreme waste of electricity.

 

Halogen

Halogen globes will look similar to incandescents, but do not have a filament between the bars. In addition, regular-looking downlights that have not been changed to energy saving fittings are likely to be halogen.

Low-voltage halogen downlights are the most commonly used light globes in Australia. However, they are a type of incandescent globe, so although they require lower voltages, they are not energy saving. In fact, each low-voltage halogen globe generates a kilogram of greenhouse gas every 15 hours, which is about the same as a standard 60 watt incandescent globe. Low voltage halogen downlights are connected directly to transformers and cannot be retrofitted with CFLs, but they can be with LEDs, making LEDs an ideal replacement for halogen downlights. Most of the LED downlights and LED globes on our website are replacements for halogen downlights.

 

Halogen globes have typically replaced incandescent globes, for example in pendant lights, chandeliers and spotlights. Newer energy saving halogens – called eco-halogens – are now available and are about 30% more efficient than incandescent globes. All of the halogen globes you’ll find on our website are eco-halogens.

 

CFL (Compact Fluorescent Lamp)

CFLs are fluorescent tubes twisted into shape to fit a standard light fitting. CFLs are about 80% more efficient than incandescent globes.
