Research firm DIGITIMES Research recently conducted a survey on the price of LED bulbs (hereinafter referred to as 40W or 60W LED bulbs) of 40W grades and 60W grade incandescent lamps in major global markets in February to understand the global LED bulb price trends. This statistic calculates the LED bulb price of the average price without considering the weight of the sales volume and compares it with the price two months ago. In the Asian region, the average price of 40W and 60W LED bulbs in the Japanese market in February 2017 was 1,406 yen (about 13 US dollars) and 1,893 yen (about 16.9 US dollars), up 1.2% from December 2016. The decline was 0.5%, the former with Toshiba rose 2.7% in February. In February, the price of LED bulbs in various markets around the world was up and down. The average price of 40W and 60W in the Korean market was 7,842 won (about 7.1 US dollars) and 12,293 won (about 11.1 US dollars), which were lower than those in December 2016. 1.4%, up 0.4%, the former was the most in the two months of LG's decline of 14.9%. The average price of 7W and 9W for the general brands in the mainland was RMB 26.5 (about US$3.9) and RMB 29, respectively, which was 0.8% higher than the December 2016 and down 4.6%. In addition, the highest prices of mainland first-line brands 7W and 9W are Tsinghua Tongfang and Foshan Lighting, respectively, at RMB 31.5 and RMB 29.9. In the European and American markets, the average price of 40W and 60W LED bulbs in the United States in February 2017 was 16.7 and 19.3 US dollars, respectively, up 5% and down 5.9% from December 2016. The former was GE's double monthly increase of 17.9%. The latter, with Philips' two-month drop of 20.4%. The average price of 40W and 60W LED bulbs in Europe is 7.0 Euro (about 7.5 US dollars) and 9.2 Euros (about 9.9 US dollars). The former is the same as the average price in December 2016, while the latter is down 2.1%. The former has increased by LG. 5.9% was the most, while the latter was the deepest with both Philips and Osram falling 4.1%. In February 2017, the highest per-unit price lumens for the 40W and 60W grades were Samsung and OSRAM in the Korean market, which were 117.4 lm/dollar and 223.7 lm/dollar respectively. In addition, the highest average luminous efficiency of the 40W and 60W grades is Mitsubishi Electric in the Japanese market, which is 95.5 lm/W and 108.2 lm/W, respectively.
Electric Parts
Some of electric parts for Tower Crane:
1. Electric motor: Tower cranes use electric motors to power the lifting and rotation mechanisms. These motors convert electrical energy into mechanical energy to move the crane's various components.
2. Control system: Tower cranes require a sophisticated control system to manage the movement and operation of the crane. This includes controls for lifting, lowering, slewing, and trolleying.
3. Limit switches: Limit switches are used to set the maximum and minimum positions of the crane's various components. They help ensure safe and accurate operation by preventing the crane from exceeding its designated limits.
4. Power cables: Tower cranes require heavy-duty power cables to transmit electricity from the power source to the crane's electrical components. These cables need to be durable and capable of handling high voltage and current.
5. Circuit breakers: Circuit breakers are essential safety devices that protect the crane's electrical system from overloads and short circuits. They automatically interrupt the electrical current flow when a fault is detected, preventing damage to the crane and reducing the risk of electrical fires.
6. Transformers: Transformers are used to step up or step down the voltage of the electrical supply to match the requirements of the tower crane. They ensure that the crane receives the correct voltage for optimal performance and safety.
7. Sensors: Tower cranes often incorporate various sensors to monitor and control different aspects of their operation. These sensors can include load sensors, wind sensors, angle sensors, and anti-collision sensors. They provide crucial data to the control system, helping to ensure safe and efficient crane operation.
8. Emergency stop switches: Tower cranes are equipped with emergency stop switches that can quickly shut down the crane in case of an emergency or safety hazard. These switches are strategically located and easily accessible to crane operators.
