In recent years, the LED industry has developed rapidly, but with the rapid development process, the industry is also showing a mixed situation. Taking indoor lighting products as an example, most manufacturers pay too much attention to cost compression, and ignore the quality of products. Low-end products are in any aspect of the efficiency, life and light quality of lamps, even with medium-quality traditional energy-saving lamps. There is no advantage at all, and it does not reflect any technical advantages and value of LED. With the popularity and promotion of LEDs, more and more people are realizing that using low-quality LED lamps is not as good as traditional energy-saving lamps. For example, a large number of low-quality LED lamps on the market are not only cheaper than the energy-saving lamps of domestic brands such as NVC and Opp, and their lifetime and efficiency are not comparable to those of energy-saving lamps. The value of existence is very small!
If the above problems are not properly recognized and adjusted, let low-end LED products enter the market, China will become the world's first LED manufacturing giant! Any LED industry practitioner has an obligation to resist the continuation of this phenomenon!
Here, we give the "LED luminaire comprehensive performance evaluation system" for LED bulbs, which refers to China's CQC certification standards and the US Energy Star certification standards, on the one hand can allow more professional or non-professionals More intuitive understanding of the comprehensive performance of the LED luminaires in front of you, and even give a quantitative evaluation of the overall performance of the luminaire, rather than being confused by the ultra-low price; secondly, through the article, we also call for Relevant departments will draw up relevant standards and regulations as soon as possible, and provide an intuitive and quantitative evaluation of all LED lighting products that have obtained relevant certifications through a similar comprehensive performance evaluation system for luminaires.
The following is a practical example to illustrate the necessity and value of the "LED Lighting Comprehensive Performance Evaluation System". The three LED bulbs in the picture below are Philips Prince's Series 12W-800LM Bulb, Fujian Wanbang Optoelectronic MCOB 9W-810LM Bulb, NVC Lighting Remote Excitation Mode Wide Angle 500LM Bulb, III Each product comes from the giants of LED lighting industry at home and abroad, and has the recognition and honor given by many institutions. The design details of the products are the model for most LED practitioners to learn. Here we temporarily put aside the cost and sales price of the lamps themselves, and compare the comprehensive performance indicators of the products separately. According to the current relevant standards, it is difficult to distinguish them. Each product is in life, light efficiency, color development, illumination angle, The lumen maintenance rate and other aspects have their own advantages. For example, Philips's product has a nominal life of 50,000 hours; although Wanbang bulbs have a nominal life of 40,000 hours, they have attracted wide attention in the industry with high light efficiency.
2. Able to process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional curved surface parts;
3. Parts that need to be processed in multiple processes after processing once clamping and positioning;
4, high machining accuracy, machining quality is stable and reliable, the pulse equivalent of CNC device is generally 0.001mm, high precision CNC system up to 0.1 m, in addition, CNC Machining also avoid operator error;
5. High degree of production automation can reduce the labor intensity of operators.
It is beneficial to the automation of production management.
6, high production efficiency, CNC milling machine generally do not need to use special fixture and other special process equipment, in the replacement of the workpiece only need to call stored in the CNC device processing procedures, clamping tools and tool data can be adjusted, thus greatly shorten the production cycle.
Secondly, CNC milling machine with milling machine, boring machine, drilling machine function, so that the process is highly concentrated, greatly improve the production efficiency.
In addition, CNC milling machine spindle speed and feed speed are infinitely variable, so is conducive to the selection of the best cutting parameters
