Shenhai Pagsabog-Patunay
Ang merkado ay baha sa iba't ibang uri ng LED pagsabog patunay na ilaw, bawat isa na may iba't ibang mga pagtutukoy mula sa iba't ibang mga tagagawa. Kaya nga, Paano pumili ang isa mula sa malawak na hanay ng mga produktong ito? Tulad ng may mga tiyak na benchmark upang suriin ang pagganap ng LED lighting fixtures, here’s a special guide to assist in the procurement process and help avoid losses in lighting projects due to inappropriate sourcing.
1. Index ng Pag render ng Kulay (CRI):
Before purchasing, it’s crucial to check the product specifications or ask the sales representative about the CRI. Sa pangkalahatan, 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. Kaya nga, 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. Ideal na, choose fixtures with frosted diffusers that emit a soft, even light.
3. Overall Luminous Efficiency of LED Lighting Fixtures:
Ang “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. Kaya nga, choose LED lighting fixtures with high lumens per watt (preferably greater than 80 lm/W; halimbawang, fixtures with an efficacy of ≥85 lm/W are a good choice).
4. LED Temperature Rise:
Karaniwan, the permissible temperatura rise for LED lights in use is between 25℃ to 30℃. Partikular na, 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. Dagdag pa, 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%. Sa paglipas ng panahon, 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. Halimbawang, LEDs from reputable brands can last over 30,000 mga oras, which is especially convenient for large-scale lighting projects.
These are the tips for selecting LED explosion-proof lights. Sana nga, this guide will assist you in making informed decisions.
