एलईडी स्फोट-पुरावा दिवे खरेदी करण्यासाठी टिपा

बाजार विविध प्रकारच्या एलईडी स्फोट-प्रूफ दिव्यांनी भरला आहे, प्रत्येक विविध उत्पादकांकडून भिन्न वैशिष्ट्यांसह. तर, या विस्तृत उत्पादनांमधून एखादी व्यक्ती कशी निवडते? LED लाइटिंग फिक्स्चरच्या कार्यक्षमतेचे मूल्यमापन करण्यासाठी काही बेंचमार्क आहेत, here’s a special guide to assist in the procurement process and help avoid losses in lighting projects due to inappropriate sourcing.

1. रंग प्रस्तुतीकरण निर्देशांक (सीआरआय):

Before purchasing, it’s crucial to check the product specifications or ask the sales representative about the CRI. साधारणपणे, 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. त्यामुळे, 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. तद्वतच, choose fixtures with frosted diffusers that emit a soft, even light.

3. Overall Luminous Efficiency of LED Lighting Fixtures:

द “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. त्यामुळे, choose LED lighting fixtures with high lumens per watt (preferably greater than 80 lm/W; उदाहरणार्थ, fixtures with an efficacy of ≥85 lm/W are a good choice).

4. LED Temperature Rise:

सामान्यतः, the permissible तापमान rise for LED lights in use is between 25℃ to 30℃. विशेषतः, 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. याव्यतिरिक्त, 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%. कालांतराने, 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. उदाहरणार्थ, LEDs from reputable brands can last over 30,000 तास, which is especially convenient for large-scale lighting projects.

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