Questions and Solutions About LED Lighting – Why LED?
1.Q: What are some great benefits of LED Lights?
A: LED (Light-Emitting Diode) Lights provide a large number of benefits over conventional light sources together with decrease electrical energy consumption, for much longer lifetime, larger sturdiness, no ultraviolet and infrared radiation, low warmth and smaller measurement.
2.Q: Can I immediately substitute my current lamps with LED lamps?
A: The LED Lights we provide are direct substitute of incandescent, halogen and compact fluorescent lamps. Which means you should not have to do any modifications to your current system.
3.Q: Why ought to I select LED lamps over the cheaper conventional lamps?
A: Take into account not solely the preliminary value of the lamp, however the true price of light, which incorporates the price of vitality, substitute and upkeep prices.
– LED lights use a lot much less vitality. When put in at purposes with lengthy work hours the saved electrical energy price can convey the payback time to lower than 2 years.
– LED lights have for much longer life, from 30,000 to 50,000 hours. Think about that you just should not have to alter your lamps for the following 20 years, particularly these laborious to succeed in light fixtures.
For industrial purposes lengthy life LED Lights imply decrease substitute prices and no extra group relamping. Considered diminished upkeep prices, the ROI (Return Of Funding) time for LED Lamps might be lower than 1 12 months.
LED lamps produce little or no warmth thus decreasing the power utilized by your air conditioner.
LED light has no dangerous UV (ultraviolet) and IR (infrared) rays.
LED lamps include NO mercury just like the fluorescent lamps. LED Lights are utterly protected for the Nature and might be disposed as odd waste.
4.Q: Will the Low Voltage LED lamps work with my current transformer?
A: Low Voltage LED lamps are appropriate with magnetic transformers used with VAC lighting. When you have an digital transformer one LED lamp might not work because of its very low power consumption. To work correctly most digital transformers require a minimal load higher than the 3-watt utilized by our LED Spot Lights. When connecting just a few LED lamps to 1 transformer the load will increase to some extent the place the usage of an digital transformer is appropriate.
5.Q: How does a LED work?
A: The LED (Light Emitting Diode) is an digital light supply that works by the impact of electroluminescence. When a semiconductor diode is turned on electrons recombine with holes and vitality is discharged as light.
6.Q: What’s the coloration of the light from a LED?
The light coloration of LED Lamps is measured by Correlated Shade Temperature (CCT) in Kelvins. Up to date Excessive Power LEDs are lined with phosphor to transform light from a blue LED to a large spectrum white light. Commonest LED Light colours used are:
Heat White (Gentle White) – 2,700 – 3,300 Okay – the colour of the light of a standard incandescent light bulb
Cool White – round 4,000 Okay – just like moonlight, xenon lamp light coloration
Daylight White > 5,000K – appears like flashlight, or typical daylight.
7.Q: What’s Shade Rendering Index?
A: The Shade Rendering Index (CRI) is measuring the flexibility of a light supply to simulate the colours of various objects precisely as compared with the daylight. Though there are critics of the subjective coloration rendering in follow, the CRI is broadly used as a measurement of the standard of the light. Increased CRI corresponds to etter high quality light, in scale from 0 to 100.
8.Q: What’s the CRI of LED light?
A: Usually LED lamps rating above CRI 80, which is larger than many different light sources. LED Lamps with CRI above 90 are used for visible inspection duties.
9.Q: How environment friendly LED lamps are?
A: The output of light sources is light and warmth. The upper the ratio light to warmth, the extra environment friendly the lamp. As we speak’s excessive environment friendly LED lights have effectivity of about 50 %, in comparison with commonplace incandescent lamp with 2-3% and fluorescent lamps with 15-20% effectivity.
LEDs naturally have directional light, which means that the light is less complicated to handle with much less losses. That presents a good higher benefit with regard to LED lamps’ excessive effectivity over all different current light sources 센서모듈.
10.Q: What’s luminous efficacy?
A: The luminous efficacy is the light output per unit power enter. It’s measured in lumen per watt (lm/W). These days commercially accessible LEDs have efficacy of 130 lm/W for cool white and 107 lm/W for heat white light (CREE XLamp MX-6). That is a lot larger in comparison with incandescent bulb that produces 15 lm/W and fluorescent lamp with 60-70 lm/W.
Nonetheless, the efficacy of a single LED shouldn’t be combined with the efficacy of the lamp. Many producers and resellers state the LED Lamp Light Output as sum of the output of the person LEDs. This isn’t right as a result of there are at all times losses from light trapped contained in the lamp. The efficacy of a LED Light Lamp, additionally referred to as LED Light Engine, might be elevated by higher design and utilizing top quality supplies.
11.Q: Is the lumen per watt the one side I ought to contemplate when selecting a LED Light?
A: No, it’s best to contemplate additionally the CRI (high quality of light) and your particular person visible preferences. Some folks just like the extra yellow Heat (Gentle) White light that resembles the light from the incandescent lamp. Different choose the brighter and extra true-color rendering Cool / Daylight white.
12.Q: What’s the lifetime of a LED Lamp?
A: When correctly put in and nicely ventilated, LED Lamps will very hardly ever burn. Nonetheless, the brightness of the LED light fade over time, so LED Lamp’s life is measured by 2 traits – how a lot will it fade after 1,000 hours of exploitation, and when the brightness will attain 70% of the preliminary worth.
High quality LED Lamps are rated at lower than 3% light output lower for the primary 1,000 hours, and 30,000 to 50,000 hours for the 70% lower, which is the usual for industrial lighting purposes.
Once more, in comparison with conventional light sources, LED lights are superior concerning lifetime.
13.Q: Does the lifetime of a LED Light Bulb shorten by frequent on/off switches?
A: Not like the fluorescent lamps, lifespan of LED Lamps is NOT influenced by frequent switching.
