Want to be the most dazzling queen in the party? An engineer named Bertho Stoltiens shared his shiny earrings Blinkring designed, The earrings have a diameter of about 31mm eardrop, the total number of 12 LED were set in a circle above. This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB), the operation of the LED parts required is a small circle on the board outside the battery.

Stoltiens came across a number of challenges when carrying out the design case，because he did not have to think a method of boosting the battery appearance, but also installing a switch, so that the wearer can easily operate. Clamp-like battery holder is made of a paperclip, Stoltiens said the very small arc on the battery holder can provide sufficient spring effect to make the battery and battery holder close bonding; other side of the circuit board is the user interface to switch , as which the paperclip structure was used, both sides seem very elegant shape.

Stoltiens said in his personal blog that the existing switching device will be used as the next version of the earring design. It is a very hard to build up the Switch light adopted now.

In addition to the challenges of the physical PCB architecture, Stoltiens also encountered some difficulties in chip programming; the Microchip's PIC12LF1552 microcontroller is used，which can not be programmed by Blinkring’s PICKit2 tools being used，the next step may be carried out by using PICKit2 Device Data File Editor . There is also a problem, PIC12LF1552 has no standard ISP head for programming.

Stoltiens thought a very simple solution that is five contacts were added on the back of the PCB and made a customized programming dock (dock), the earrings can be held when needing to be updated. The spacing is 100mi on the PCB pad (pad) , therefore by using the contacts on the vertoboard be used as the programming base.

Blinkring circuit board programming method

The LED was distributed in six points on the earrings, each point has red and green LED; Stoltiens was originally hoping to achieve the unity brightness through hardware method, but finally using the software to make LED glow to reach a satisfactory. The method adopted is to maintain that the shiny time of the green LED light is twice longer than of the red .

There are several kinds of LED light mode for the earrings, just press the switch button can be switched; And the LED light can’t be turn off until you push the button for long time, and then gently press once to start. Stoltiens expressed, Blinkring battery life can reach 100 to 200 hours, while you can sustain more than 1 year if in the sleep state.

LED lighting is designed in the earrings, which is a particularly novel and unique method that can add highlights for many ladies to make them become the focus of attention，apparently LED lighting is closely connected to design to bring us the extraordinary experience and unique enjoyment. Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where need higher brightness lighting to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while LED tube light and LED flood light use low voltage constant current driver, which current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Morning of the 30th, the energy-saving projects of the underground parking lot lighting system in Yantai City Cultural Center was in full swing, the project will eliminate the original traditional lighting, 800 sets of LED tube light will be unified installed, energy saving is up to 70%.

According to the introduction of Wang Shouyi of the municipal management and maintenance of the engineering department at the Plaza, the fluorescent tubes that have been used for nearly six years were installed in the original cultural center parking, which need to be turn on for lighting due to underground around the clock, after a long period of use, most shade has aged and dropped off.

"Over the past two years, we have maintained and replaced the lights for more than 500 times, if not timely transformation, which will bring significant safety hazard to the pedestrian and vehicular." Wang Shouyi said.

It is understood that the LED tube light currently installed has greater brightness and less power consumption compared to the traditional lighting sources,.

" By the transformation of the energy-saving LED tube light，while saving the electricity, increasing the parking lot lighting levels, probably more than 30%, thus greatly improving the vehicle's driving safety." Yun-liang who is a director of conservation Municipal Yang Plaza Property Management Office said .

According to the site construction personnel, this LED energy-saving light sources, each lamp power is only 20 watts, compared to the previous two tubes each 72 watts of power, can save electricity more than 70%.

The installation is expected be completed within a week

At the scene, three, four workers are busy in tensely mounting on the scaffold, according to of introduction Yun-liang director, there are over 600 parking spaces throughout the underground car park at the cultural centers, more than 800 groups lights, the installation process is divided into four groups, each group is three to five people, which is expected to be carried out to centralized replacement within a week.

"There are usually many parked vehicles, in order to ensure smooth and safe completion as soon as possible, we have set up a special construction safety security team to supervise and command installation and construction on-site, taking partition isolation to avoid the peak period of vehicles, or construction at night and other measures to minimize impact the owners make on parking. "Yu director told to reporters.



Yantai is an important cultural and economic center in Shandong Province and the third largest city which is only to Jinan and Qingdao, large number of the LED tube light is adopted as parking lamp in Shandong government agenciess， which is enough to prove that the LED light due to energy saving and environmental protection get the unanimous approval of the municipal government,Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where need higher brightness lighting to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while LED tube light and LED flood light use low voltage constant current driver, which current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Experienced the "cold" in 2012, the overall market trend of LED light is clearly warmer in the first half of 2013, with accelerated phase-out of the incandescent lamps, LED lighting penetration is significantly faster, market incipient outbreaks.

1, the lighting market: LED lighting penetration may speed

Under the impact of the economic environment at home and abroad, the overall external demand of the electrical and lighting industry is weak, domestic demand is not busy, the growth rate decline over the previous years in 2012. the lighting industry picked up in the first half of 2013, the revenue growth of the main business returned 16.78%, the above-scale enterprises realized main business income that is 74.618 billion in the first three months, the total profit is 3.902 billion, the overall profit margin is 5.23%.

On the other hand, in 2013, the penetration pace of the LED lighting market may speed. As the technology development led to improvement of the light efficiency, as well as the upstream LED chip overcapacity caused that the prices were dropped significantly, LED lighting product prices have started to reach the critical point mass the market can accept. Expected in 2013,as the alternative routes of the incandescent into the real implementation phase, various manufacturers have increased marketing and distribution channels, LED lighting will be a major breakthrough in commercial lighting and outdoor lighting such as the LED flood light and LED tube light. Previously, according to CSA production research estimates, in 2012, LED lighting market penetration is about 3.5%, which is expected rise to about 10%in 2013.

From historical data, we can see that since 2009, the average profit margin of the overall industry began to rise significantly, climbing from 3.49% in 2009 to 6.87% in late 2011; fell slightly in early 2013. In fact, LED lighting began to penetrate market in 2009, with the penetration gradual increase, the high-margin of the LED lighting lead that the entire industry profit margins improved. In early 2013, as the price of the LED light decreased, the industry profit margins began to fall.

2, incandescent phase out effects appear negative growth in production

From the completion of the production situation, the overall yield of the overall lighting market continues to maintain the 20% growth rate, but the main category began to differentiate, incandescent substitution effect is starting to show. Over the past year, the growth rate of the incandescent showed a decreasing trend quarter by quarter， which began to be negative growth on March 2013. In contrast, other NES is complementary with incandescent showed significant，since the beginning of 2012，the growth rate -5.97% continued to increase, and since 2013 began to clear high growth , the growth rate were maintained above 30% on February-May .

Indeed, with the national phase-out incandescent roadmap released，ban sale of 100 watts and above ordinary incandescent lighting on the import began to be formally implemented on October 2012, in 2013 the production side has been significant capacity contraction. Therefore, I believe that along with the road map continues to advance, the market penetration of the alternative lighting products will be significantly improved, LED lighting market will into the outbreak recent years.


Under the impetus of the good market policies and circumstances，a large number of excellent LED manufacturer have been emerging, Lead lighting is one of them.Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while LED tube light and LED flood light use low voltage constant current driver, which current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

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.
