Characteristic
The container of the sealed refrigerated truck needs to be strictly sealed to reduce the heat exchange with the outside, so as to ensure the lower temperature in the refrigerator.
Refrigerated truck
The refrigeration equipment is connected with the container and provides a steady stream of refrigeration to ensure that the temperature of the container is in the range of the goods permitted.
Portability is generally used in refrigerated trucks transport goods are not for a long time to save the items, although there are refrigeration equipment, still need to quickly reach the destination.
A container similar to a heat insulated refrigerated truck is made of a material with better heat insulation effect, and the heat exchange is reduced.

The evaluation indicators of lighting products are divided into four aspects.
The first is the safety requirements. LED lighting products mainly carry out testing related to GB7000.1 standards, including: lamp structure, internal and external wiring, grounding requirements, protection against electric shock, dust, solid foreign matter and waterproof, withstand voltage, Insulation resistance test, creepage distance, clearance, durability and heat test, as well as heat, fire and flame resistance of materials. With the popularity of LED products, the harm of blue light to the human retina is becoming more and more important. In view of such hazards, the evaluation requirements for optical radiation safety have been added in the new GB7000.1-2015. As a lighting company with responsible and excellent technology, Op Lighting will minimize its harm in all aspects.
  Â
Secondly, the performance requirements, the general evaluation content of the lighting product performance indicators mainly include: optical characteristics, electrical characteristics, color characteristics, thermal characteristics, life characteristics, reliability and so on. Among them, optical performance is a very important indicator. A good lighting product can provide a comfortable and warm lighting environment, which makes people feel relaxed and happy. The relevant characteristic indicators to achieve this effect mainly include the following aspects:
(1) Light characteristics mainly include: light intensity distribution, initial light effect/light flux, light intensity/illuminance and glare requirements;
(2) Electrical characteristics mainly include: lamp power and power factor;
(3) The color characteristics mainly include: correlated color temperature, color rendering index, chromaticity coordinates, chromaticity tolerance, color distribution non-uniformity and color space uniformity;
(4) Thermal properties mainly include thermal resistance and junction temperature;
(5) Life characteristics mainly include switching times test, life/acceleration life test, lumen maintenance rate (light flux maintenance rate), light intensity maintenance rate, etc.
The third is electromagnetic compatibility. The electromagnetic compatibility evaluation indicators in lighting electronic products include: conduction, radiation, harmonics, surge, group pulse, voltage drop, etc., among which conduction, radiation and harmonics are mandatory requirements. Op Lighting strictly requires all products to meet the limits of relevant standards, to ensure that the lighting products do not affect the normal operation of the surrounding electrical appliances during use, and are not affected by the surrounding electrical appliances.
Finally, reliability is based on testing, which simulates different space environmental conditions to ensure that the product works properly. The test items include: high temperature aging, low temperature start, alternating heat and humidity, high and low temperature cycle, thermal shock, salt spray test, etc. Every simulation of Op Lighting is strictly controlled, and every product is not only qualified, but also able to adapt to the smooth operation in different environments.
Testing laboratory requirements
According to the above evaluation indicators, we need to ensure that the products meet the requirements of the indicators, and the testing laboratory also has sufficient testing equipment and related testing capabilities. Op Lighting Lab currently has first-class testing equipment at home and abroad, and has established safety laboratory, durability laboratory, material laboratory, IP laboratory, EMC laboratory, optical performance laboratory, reliability laboratory, aging life. Laboratory, etc. At present, the laboratory has the qualification of ISO/17025 national accredited laboratory, TüV witness laboratory qualification and self-ballasted LED lamp energy efficiency labeling testing laboratory qualification.
