എൽഇഡി സ്ഫോടന-പ്രൂഫ് ലൈറ്റുകൾ വാങ്ങുന്നതിനുള്ള നുറുങ്ങുകൾ

വിവിധ തരം എൽഇഡി സ്ഫോടനാത്മക ലൈറ്റുകളാൽ വിപണി നിറഞ്ഞിരിക്കുന്നു, ഓരോന്നിനും വ്യത്യസ്ത നിർമ്മാതാക്കളിൽ നിന്നുള്ള വ്യത്യസ്ത സവിശേഷതകളുണ്ട്. അങ്ങനെ, ഈ വിപുലമായ ഉൽപ്പന്നങ്ങളിൽ നിന്ന് ഒരാൾ എങ്ങനെ തിരഞ്ഞെടുക്കും? LED ലൈറ്റിംഗ് ഫർണിച്ചറുകളുടെ പ്രകടനം വിലയിരുത്തുന്നതിന് ചില മാനദണ്ഡങ്ങൾ ഉള്ളതിനാൽ, here’s a special guide to assist in the procurement process and help avoid losses in lighting projects due to inappropriate sourcing.

1. കളർ റെൻഡറിംഗ് സൂചിക (സി.ആർ.ഐ):

Before purchasing, it’s crucial to check the product specifications or ask the sales representative about the CRI. പൊതുവെ, LED lights with a CRI between RA80 and 100 exhibit excellent color performance; those between RA50 and 79 have average color performance, while lights with a CRI below Ra50 have relatively poor color rendering. അതുകൊണ്ടു, it’s advisable to select LED lighting fixtures with a high CRI.

2. Avoid Glare:

Glare significantly impacts the quality of lighting and should be minimized. Opt for lights that do not produce glare. ആദർശപരമായി, choose fixtures with frosted diffusers that emit a soft, even light.

3. Overall Luminous Efficiency of LED Lighting Fixtures:

ദി “luminous efficiency” of a finished LED light is the total luminous flux emitted by the LED under rated voltage divided by the total power consumed, measured in lumens per watt (lm/W). The higher this value, the better the energy-saving effect, and the less electricity used. അതുകൊണ്ടു, choose LED lighting fixtures with high lumens per watt (preferably greater than 80 lm/W; ഉദാഹരണത്തിന്, fixtures with an efficacy of ≥85 lm/W are a good choice).

4. LED Temperature Rise:

താരതമ്യേനെ, the permissible താപനില rise for LED lights in use is between 25℃ to 30℃. പ്രത്യേകം, the temperature on the LED’s heatsink is the ambient temperature plus the allowable temperature rise. That means, if the ambient temperature is 37℃, the temperature on the LED heatsink should be 67℃ (37℃+30℃). If it exceeds this, the temperature rise is considered non-compliant. Heat is the enemy of LED performance; the less heat produced, the higher the luminous efficiency of the LED light. അധികമായി, a rapid rise in temperature on the heatsink indicates high thermal conductivity and low thermal resistance of the LED lighting fixture.

5. LED Lifespan:

The initial luminous flux of a new light is 100%. ഓവർ ടൈം, the luminous efficiency of the light will decrease. The lifespan of an LED is the time it takes for its luminous flux to reduce to 70% of the initial flux. Naturally, the longer the better. ഉദാഹരണത്തിന്, LEDs from reputable brands can last over 30,000 മണിക്കൂറുകൾ, which is especially convenient for large-scale lighting projects.

These are the tips for selecting LED explosion-proof lights. പ്രതീക്ഷയോടെ, this guide will assist you in making informed decisions.
