Comparison with the performance of the LED light and the cold cathode lamps

1, the contrast between the two theoretical life

LED light source life is 50,000 hours, if the lights is lighted up for five hours a day, the life expectancy is up to 55 years; the life of the cold cathode light is 30,000 hours,lighted up for 5 hours a day,its life is expected to be 16 years.

Conclusions: Both sources require power driver and lamp housing, the life of the existing electronic power and the shell lamp expectancy is10 years, so the actual life of the two lamps should be 10 years.

2, energy (luminous efficiency) compared

Take the luxeon for example: red LED, 44 lm / W; red cold cathode tubes 18 lumens / watt. Green LED, 30 lumens / watt; green cold cathode tubes, 88 lumens / watt.

Conclusion: Red LED lights save more electricity than red cold cathode lamp. Green cold cathode lamps power than the green LED lamps. Similarly lumens, power consumption is only 10% -20% of incandescent lamps, both of which are highly efficient, energy-saving green light.

3, moisture-proof performance comparison

Because LED lighting work in low voltage high current,so the requirements on the moisture resistance are relatively high; since the cold cathode lamps work in the high、small current, its moisture resistance properties particularly good.

Conclusion: the moisture resistance of LED lamps need to be strengthened, the cold cathode lamps are especially suitable for other lights that can not be used wet environments)

4, shock resistance compare

Seismic the performance of the LED lamps is particularly advantageous; the cold cathode light is made of glass, its seismic performance is slightly worse than the LED, but have excellent seismic performance over other types of hot cathode lamps.

Conclusion: Both are earthquake-type lamps, can be used in place where the vibration is relatively strong.

5, beating color contrast

LED light source: can beat, regulator discoloration ;which does not affect the life of the product. Either do the Cold cathode light

Conclusion: Both can be used in where needs a beat changes, the regulator discolored.

6, color contrast

LED light colors: red, green, blue, white, yellow, color. Cold cathode light colors: white, red, pink, orange, pink, colored yellow, bright yellow, milk, yellow, green, green, green, light blue, blue, violet, purple, color.

Conclusion: Both colors are rich, not only can be used as lighting, but also can be used as decorative lighting.

7, the appearance of contrast

LED light source is point-like, it can also be connected as the line or surface and designed for a large-scale, the lighting appearance is abundant. the shape of the Cold cathode light source itself affects the appearance of the entire lighting aesthetics.

Conclusion: LED lamps as the light source can be designed for larger scale.

8, underwater work performance:

LED lamps are generally low lighting, it is safe to work  underwater and widely used as underwater lights, buried lights. Cold cathode lamps are generally high-voltage input, or the ground and underwater is not suitable for work.

How to uniformly distribute the LED energy to form a uniform illumination

As LED technology continues to progress, the white LED technology is getting more mature, LED’s advantages is more obvious, which will become the fourth-generation light source after the flames, incandescent, fluorescent, the point of view has been widely recognized. But the LED due to its exceptional Lambertian light distribution characteristics, resulting in a great waste of light in the popularization ,the distribution of LED light intensity is shown in Figure 1. How to uniformly distribute the LED energy to form a uniform illumination on the lighting surface so that achieve the advantages of maximizing LED energy, which has been a difficult problem.

When we designed Uniform illumination in the past, we used many different methods, such as square rod (integrator rod), fly’s eye lens and so on. However, these optical systems have many shortcomings, square bar lighting system through square bar multiple reflections will cause energy loss,when the fly’s eye lens through the lens,which can also cause energy loss, thus reducing the utilization of solar energy .

LED light-emitting characteristics limit its own application in the lighting field, how to LED reasonably distribute energy to form an ideal surface illumination is a problem worthy of study. How to design optical to analysis in the different applications, by using the optical Spreading conservation of non-imaging optical design to obtain lens equations so that respectively achieve circular uniform illumination and rectangular uniform illumination, in which the uniformity of circular illumination illuminance reach 85 %, the uniformity of rectangular lighting illuminance is up to 75% and established the freeform lens three-dimensional model and combined Tracepro raytrace. Simulation results show that: the proposed method meet the appropriate lighting standards and verify that the theoretical design is reasonable.

The lead lighting adopts unique optical design to ensures the illumination uniformity of the rectangle lighting surfaces of the  LED flood light and LED tunnel light and other high power outdoor lighting reach at least 75% to form a uniform illuminance on the lighting surface,which greatly reduces the waste of the light and improves the light’s utilization ratio, login to learn more design philosophy and product characteristics of the LED lighting.

Wonderful design: LED flashlight use hand heat to glow

Many people have such unpleasant experience: When you need a flashlight, which can be found but we can not find the battery to light it, if without the help of a flashlight battery to emit light, then the problem can be well solved.

Ann Marco Brzezinski (picture from therebelution)

Recently, from Canada, a 15-year-old girl Ann Marco Brzezinski (Ann Makosinski) invented an eco-friendly flashlight, which can emit light without using batteries.

The flashlight takes advantage of the thermoelectric effect to work and depends on the heat of user’s hand and the environmental temperature to produce electricity. Led scientists suspect that the human body can produce enough heat to maintain the flashlight battery, the latest flashlight the girl design did not use full of the body heat, only palm heat.


Ann Marco Brzezinski and LED flashlight she invented (picture from therebelution)

LED light make this flashlight easier, she measured that the palm heat can generate about 57 milliwatts power, LED lights need to maintain about 0.5 mW power, the light flashlight release is very soft, but it is enough to find your keys or illuminate a book page.

It is reported that if the Google Science Fair Jury appreciate this invention, it is expected to grant its super Invention Award.

The flashlight Ann Marco Shinseki invented utilizes thermoelectric effect and also benefits from the low-power LED lights to work better. By eliminating the need to replace the battery, this flashlight bring us convenience in lighting and also reduce environmental pollution, we also hope that it will be start mass-produced as soon as possible. Meanwhile, we found that LED lighting increasingly close ties with life, LED lighting because of semiconductor lighting, in addition to saves energy and reduce more environmental pollution, and energy-saving than traditional fluorescent lamps,what more obvious advantages is better integrate technology, arts, medicine, agriculture and other fields and constantly innovate to give us odd experiences and convenient services, and now LED lighting as outdoor decorative lighting has been enjoying a great popularity, such as LED flood light due to Octagon irradiation area and soft light, high brightness, energy saving and environmental protection, waterproof, dustproof, resist-shock, and long service life greatly saves manpower and resources, it has been bringing us better lighting experience in city squares, stadiums, parks, railway stations, airports, artificial fountains, the facades of large commercial building and hotel and other outdoor venues Lead lighting adopts high-quality integrated COB LED as source and the low-voltage constant current as driver to ensure the alternating current is converted into direct current, while greatly improving the utilization and ensure the light is soft and non-glare, log in to experience more enjoyment the professional LED lighting brings.
