Correctly understand the standard content, adhere to the development of LED specifications and standards

At present, compulsory standards mainly rely on law enforcement supervision departments to promote implementation, a large number of recommended standards basically rely on the independent choice and implementation of enterprises, and the implementation of guiding technical documents is weaker. The lack of effective policy guidance and incentives has led to the failure to implement many standards and severely constrain the improvement of LED products. As far as "urban road lighting" is concerned, there is no standard. There are standards that are not implemented, and they are turned a blind eye. Most LED streetlight companies now focus on promoting energy conservation, do not implement these standards, and do not design, manufacture, and test according to standards. Since 2007, the LED street light enterprises, which have been on the market for more viewers, have publicized the uniformity of illumination of LED street lamps and the uniform illumination of rectangular spots. They have spread widely, causing misguided guidance, wasting a lot of manpower, financial and material resources, and only used As the evaluation standard, illuminance obviously has serious differences on the understanding, understanding and selection of standards and testing methods, and it does not really understand the connotation of standards.

LED standards are re-established, repeated standards, multiple standards, and the loss caused by many of these situations is not just unnecessary waste caused by repeated construction. A more serious potential is that small industries, even small groups, are for their own interests, forcing the implementation of inappropriate standards within their own sphere of influence, and there are multiple standards in large industries, and they are independent. Under this circumstance, our LED standard can not form a complete system, not only can not protect the national industry from the outside, but also can not guide the healthy and orderly development of the industry. Management and people of insight in the industry should pay great attention to this. The mechanisms for the establishment, formulation and release of standards should be improved with the times. Traditional high-pressure sodium lamps, metal halide lamps, etc. have a uniform series of specifications, which makes these products very interchangeable. LED enters the field of general lighting, and it is also necessary to carry out standardization of series specifications as soon as possible. This is also the mature performance and inevitable way of the industry.

The international standard research on LED lighting equipment is still in its infancy. As a major country in the production and use of lighting products, China should focus on the research work on LED lighting equipment standards to promote development through application. Moreover, it is necessary to carry out the development of product standards for LED lighting fixtures and energy-saving certification work in a focused and step-by-step manner for different semiconductor lighting products. At present, it is especially important to promote the standardization of the series of LED lighting appliances. The standard development cycle is long and the update is slow, while the effective period of the specification is short, the impact surface is small, and there is a certain time effect and application range. According to the characteristics of different products, preliminary quality assessment indicators and assessment methods are proposed, and the preliminary technical specifications of the series of products are gradually formed. It is recommended as a technical standard in the industry or in certain areas, and is gradually revised in use. When the time is ripe, the competent department will organize the review and revision, and form a draft for the national industry standard (Ministry) or national standard. .

This year, the semiconductor lighting standards have been basically improved, and various application fields have a relatively complete standardization system. Enterprises and application departments should read standards, correctly understand standards, select standards, and strictly enforce standards. Products must be sent to third parties for testing. Raise the threshold, strictly grasp and guarantee the quality, eliminate the backward products, resolutely stop the low-quality and inferior products from flooding the market, and cannot make the semiconductor lighting energy-saving industry into an industry that wastes resources and consumes energy, and cannot let consumers lose confidence in LED products.

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.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●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.
