Edited at 2025-03-01 11:38:01Rumi: 10 dimensions of spiritual awakening. When you stop looking for yourself, you will find the entire universe because what you are looking for is also looking for you. Anything you do persevere every day can open a door to the depths of your spirit. In silence, I slipped into the secret realm, and I enjoyed everything to observe the magic around me, and didn't make any noise. Why do you like to crawl when you are born with wings? The soul has its own ears and can hear things that the mind cannot understand. Seek inward for the answer to everything, everything in the universe is in you. Lovers do not end up meeting somewhere, and there is no parting in this world. A wound is where light enters your heart.
Chronic heart failure is not just a problem of the speed of heart rate! It is caused by the decrease in myocardial contraction and diastolic function, which leads to insufficient cardiac output, which in turn causes congestion in the pulmonary circulation and congestion in the systemic circulation. From causes, inducement to compensation mechanisms, the pathophysiological processes of heart failure are complex and diverse. By controlling edema, reducing the heart's front and afterload, improving cardiac comfort function, and preventing and treating basic causes, we can effectively respond to this challenge. Only by understanding the mechanisms and clinical manifestations of heart failure and mastering prevention and treatment strategies can we better protect heart health.
Ischemia-reperfusion injury is a phenomenon that cellular function and metabolic disorders and structural damage will worsen after organs or tissues restore blood supply. Its main mechanisms include increased free radical generation, calcium overload, and the role of microvascular and leukocytes. The heart and brain are common damaged organs, manifested as changes in myocardial metabolism and ultrastructural changes, decreased cardiac function, etc. Prevention and control measures include removing free radicals, reducing calcium overload, improving metabolism and controlling reperfusion conditions, such as low sodium, low temperature, low pressure, etc. Understanding these mechanisms can help develop effective treatment options and alleviate ischemic injury.

Precautions for UL certification of outdoor and indoor lamps
Structural safety
Material selection
Weather-resistant materials are required for outdoor lamps
Waterproof materials to deal with bad weather
UV-resistant material to resist UV erosion
Fireproof materials are required for indoor lamps
Prevent fire risk
Weather resistance
Outdoor lamps
High waterproof performance requirements
Need to meet IP65 standard
UV resistance performance requirements
Long-term exposure to sunlight does not fade or brittle
Indoor lamps
Fire resistance performance requirements
The material is not flammable and has good flame retardant
Anti-corrosion of metal parts
Outdoor lamps are preferred
Anti-corrosion treatment
Electroplating, coating and other methods
Case protection level
Outdoor lamps
IP65 standard
Completely dustproof and waterproof
Indoor lamps
IP20 standard
Basic dustproof capability
Mechanical strength
Outdoor lamps
Resistant to wind and snow loads
Stable structure and can withstand natural environment pressure
Indoor lamps
Installation stability
If the chandelier needs to consider the load-bearing capacity
Electrical Safety
Insulation and spacing
Creep distance and electrical clearance meet standards
Prevent electrical short circuits
Double insulation/reinforced insulation
Special requirements for outdoor humid environments
Provides additional protective layers
Terminal reliability
Prevent loosening
Outdoor needs to adapt to temperature changes
Use of temperature-resistant materials and designs
Overcurrent protection and grounding
Fuse/Circuit Breaker Configuration
Prevent overload
Grounding Continuity Test
Outdoor mandatory requirements
Ensure safety of grounding
Performance Testing
Temperature test
The temperature rise does not exceed the standard under maximum load
Sunlight radiation needs to be considered outdoors
Test performance stability at high temperatures
Pressure test
High voltage insulation test
For example, 1000V lasts for 1 minute
Ensure the pressure resistance of the insulating material
Leakage current test
Leakage current ≤0.5mA
Strict outdoor control
Reduce the risk of electric shock
Aging test
Outdoor lamps
UV aging, salt spray test
Simulate long-term outdoor use conditions
Indoor lamps
Long-term lighting stability
Test performance after long-term use
Environmental adaptability
Waterproof and dustproof
Outdoor lamps
IPX5 water spray, short-term water immersion test
Such as IP67 standard
Anti-corrosion
