LED chip industry overall fluctuations
In terms of the long-cycle dimension, the LED chip is continuously developed under the driving of “Haize's Lawâ€, and it alternately grows in different fields such as backlight, illumination and display, and the application field and market scale continue to expand. In the short-cycle dimension, due to the mismatch between the supply and demand of LED chip capacity and the negative feedback caused by the amplification effect caused by Over booking in the industry chain, the LED chip industry also has periodic characteristics under the game of supply and demand. .
Short-term view: 1H2018 supply and demand resonance, LED chip profit is relatively stable
As far as the supply side is concerned, when the leading manufacturers rationally expand the factory, it is estimated that the global LED chip production capacity of 1H2018 will increase by only about 5% compared with 4Q2017 (without considering the capacity exit); on the demand side, LED lighting is expected to be 2018. With a year-on-year increase of about 10%, the small spacing in the LED display maintains a growth rate of around 30%. Other sub-segments such as automobiles also have the potential for rapid growth. Overall, the demand side is expected to grow by 8 to 9%. Therefore, 1H2018 LED chip supply and demand is in a weak balance, the price will remain orderly.
Mid- and long-term perspective: LED applications continue to expand, and future price declines will slow down
The penetration rate of the LED lighting market is expected to continue to increase, and the small-pitch LED display will maintain a high growth rate. The Micro LED/Mini LED is expected to open up the LED growth space, and the downstream application fields will bloom more, and the demand for LED chips is expected to maintain a high growth. speed. At the same time, it is expected that the marginal benefits of improving light efficiency will gradually decrease in the future, and the improvement of light efficiency will slow down. Therefore, the cost reduction will also slow down. In the medium and long term, the decline in LED chip prices will tend to be flat.
Capacity transfer, the mainland LED chip leader strong Hengqiang
With the support of local governments, mainland LED chip manufacturers have actively expanded their production by relying on the advantages of capital and scale. The production capacity of LED chips has shifted to the mainland, and the industry concentration has increased significantly. According to data from the High-Tech Research Institute LED Research Institute (GGII), the output value of LED chips in China reached 18.8 billion yuan in 2017, accounting for nearly 40% of the global LED chip production; an increase of 29.7% compared with 2016. In recent years, the localization of MOCVD equipment has helped domestic leaders to consolidate their competitive advantages. At the same time, Sanan Optoelectronics and Huacan Optoelectronics have integrated sapphire substrates upstream, and mainland China LED chip leader Hengqiang.
12V
Dc Motor Can drive under the rated voltage 12 v dc motor, most of the products our company can achieve the 12 v voltage drive, speed can be customized according to customer demand.
Characteristics: 12V dc
motor With torque, low noise, small size, light weight, easy to use, constant speed operation, etc, also can match all kinds of reducer in order to achieve the purpose of changing the output speed and torque
Application field: 12V Dc Motor part of the armature iron core, armature, commutator and other devices, dc motor is suitable for most of the electronic products, such as electric toothbrush, razor, medical apparatus and instruments, breeze machine, mixer, etc
Method of use: the best stable in horizontal plane, installed on the 12V dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the 12V dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
12V dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a 12V dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
12V dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry. Welcome to our factory.
