As an important traditional lighting production and export base in China, Ningbo has rich manufacturing experience and channel resources accumulated in the traditional lighting era. However, with the advancement of LED technology, LED has become a new force in the lighting industry. Although the data in Ningbo in the first half of this year is relatively beautiful, compared with many cities in Guangdong, the new manufacturing center of LED industry, Ningbo is still in a disadvantage.

In the past two years, due to the uneven quality of LEDs in Guangdong, Ningbo LED manufacturers can clearly feel the enthusiasm of international buyers. However, due to the lack of competitiveness of LED products in Ningbo and the continuous improvement of the quality of LED industry in Guangdong, the scale of the industry continues to expand. Foreign purchasing power has also gradually shifted to Guangdong.
"Ningbo is still a blank in the upstream chip field, lacking core technology; the mid-stream packaging foundation is weak, only about 15% of enterprises are involved." Gao Xiao LED CEO Zhang Xiaofei said that the cost of purchased components is high, the price is still low; The quality can not be guaranteed, the quality of the product is difficult to control, and it is not conducive to export to Europe and the United States with high quality requirements.

1. High design experience: First of all, the high-power LEDs of different brands have different chip structure, packaging method and light characteristics, which will cause the same lens to be different with different specifications of brand LEDs; therefore, it requires targeted development ( Mainstream brands are oriented) to achieve the desired results.
2. The optical design software is proficient: (such as Code TracePro, ASAP, LighTools, etc.) and mechanical modeling software (such as: Pro/E, UG, SOLWORKS, etc.) for design and optical simulation, and continuously optimized to obtain the corresponding optical lens.
3. The precision of the mold is extremely high
The processing precision of the optical surface of the lens should be 0.1μm, ultra-precision machining machine CNC surface profiler, aspherical interferometer and so on. The Swiss S136 mirror steel is heat treated to 55°, and is subjected to nickel processing on the rough embryos and then subjected to surface machining using an ultra-precision machining machine.

IES LM-79: Photoelectric performance test standard (test items in the ES LM-79 standard mainly include total luminous flux, luminous efficiency, light intensity distribution, chromaticity coordinates, correlated color temperature, color rendering index, and color space non-uniformity.)
IES LM-80, TM-21: Life Test Standard
EU ERP Directive (LED energy efficiency requirements, functional requirements, product information requirements, etc.): In recent years, China has attached great importance to LED standardization work from country to country, and relevant standards are not only perfected (Ministry of Industry and Information Technology released) Nine semiconductor lighting electronics industry standards such as SJ /T 11395 - 2009 "Semiconductor Lighting Terminology". National Semiconductor Lighting Engineering R&D and Industry Alliance also released 7 items such as LB / T001 - 2009 "Integrated LED Street Lamp Test Method" Relevant technical specifications for LED lighting products. The Ministry of Construction has issued standards for urban road lighting, traffic signal lights, and related standards and technical specifications for LED street lights and signal lights for railways and highways.

The small appearance and size of the One Hand Gaming Keyboard is one of the key points for users to choose.The maximum length of the keyboard in one-handed games is usually only half or even less than one third of the standard keyboard.The most comfortable position for both hands is usually slightly larger than the shoulder width of the player (the distance between the tail fingers of both hands is about 500-650mm).When using the standard keyboard, between the mouse and the keyboard. The clearance for Gaming Mouse movement is usually no more than 100mm(standard 104-key keyboard length is about 450mm). And the use of one-handed game keyboard, can let the player play with a wide mouse movement space, so that players enjoy a more rapid and flexible mouse operation.
Due to the limited size of one-handed gaming keyboards, the number of surface keys usually does not exceed the number of keys in the main key area of a standard keyboard (61 keys). Although the current PC games are designed with the first left hand key area, some secondary keys are still designed in the right hand key area for the convenience of players' memory and game operation.
For the one-handed game keyboard, comfortable ergonomic design, is to allow players to maintain long-term combat effectiveness of the basic guarantee. However, it is different from the ergonomic design of mouse in that players often move their fingers up and down and left and right when using the Gaming Keyboard.The ergonomic design that is too close to the palm will lead to the restriction of finger movement. Therefore, the ergonomic design of the one-handed game keyboard must be carried out in order to ensure that the player's finger operation is not affected.
