The US Department of Energy (DOE) has announced the ENERGY STAR "Second Draft of Performance Standards for Three SSL Lamps", including: outdoor pole-type lamps and road lighting, outdoor wall-mounted lighting and parking lot lighting .
   The DOE said that the current draft standard is due to:
   • These new products are being launched on a regular basis;
   • Energy efficiency projects, municipalities and other project investors indicated that they should attach great importance to the application of these products;
   • These listed luminaires have been tested by the CALiPER project and the results show that these luminaires have a wide range of performance;
   • The demonstration project was hosted by the GATEWAY project team of the Utilities, Municipalities and Energy Departments, indicating that these luminaires have the potential for energy savings, and for these applications it is also necessary to define minimum standards of performance.
   The US Department of Energy has also defined FTE (fitned target efficacy) indicators for quantifying the performance of outdoor pole-type luminaires because other existing independent project metrics do not adequately measure the performance of the luminaires, so that these luminaires will Delivered to a predetermined target area.
   The proposed “A†(short-term application) standard adds lighting for outdoor and parking area areas. The lamps covered are as follows:
   1. Outdoor pole type and road lighting: In terms of application, the minimum light output of the luminaire is required to reach 1000 lm (initial luminous flux), regardless of whether the luminaire is protective or unprotected, the output power is high or low, and the luminaire is specific The minimum level of target performance will also change.
   2. Outdoor wall-mounted lighting fixtures: In addition to other indicators, in terms of applications, the minimum light output of the fixture is required to reach 300 lm (initial luminous flux).
   3. Parking lot lighting: In addition to other indicators, in terms of application areas, the minimum light output of the luminaire is required to reach 2000 lm (initial luminous flux).
As of July 31, 2009, the US Department of Energy will invite project investors to review and comment on the draft of the second draft.

3D printing on the pen machine is mainly used in 3 d printing pen, is made from a special custom Dc Gear Motor, mainly used in 3 d printing pen, pen 3 d printing machine has been updated three generations according to the requirements of product.
3D Printing Motor product introduction:
The 3D Printing Motor is based on the deceleration Motor, coupled with supporting gears and ball bearings.The role of the gear reducer is to provide lower speed and greater torque.At the same time, gear box different deceleration ratio can provide different speed and torque.It's mostly rolling.
Features: 3D Printing Motor, small size, large torque, low noise, durable, low energy consumption, customized power design, convenient installation and maintenance;
Simplify design and save space.
Features: usually used financial equipment, office equipment, electronic locks, wireless charger, remote control toys, precision instruments and meters, automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows, etc., wide application range
Method of use: the best stable in horizontal plane, installed on the 3D Printing Motor output shaft parts, cannot use a hammer to knock, knock prone to press into the 3D Printing Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
3D Printing 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 3D Printing 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:
3D Printing 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 3D Printing Motor 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.
