How to select Led Lighting

Are there some people like facility managers, building owners, and among’s customers? I think Yes. You wonder the way how they choose, right? I’ll tell you.

lights depends on their unique characteristics, they are:

1. Directional Light Emission

Unlike all directions emission of traditional light sources, LEDs emit light hemispherically mounted on a flat surface, so they reduce wasted light.

2. Low Profile/ Compact Size

The small size and directional light emission of LEDs offer the potential for innovative, low-profile, compact lighting design. The LED parking structure light shown here is only 6 inches high, compared to a common metal halide parking garage fixture almost 12 inches high. In parking garages with low ceilings, that six-inch difference can be valuable. For directed light applications with lower luminous flux requirements, the low profile benefit of LEDs can be exploited to a greater extent. Under-, over-, and in-cabinet LED lighting can be very low-profile, in some cases little more than the LED devices on a circuit board attached unobtrusively to the cabinetry.

3. Breakage Resistance

Traditional light sources are all based on glass or quartz envelopes. Product breakage is a fact of life in electric lamp transport, storage, handling, and installation. LEDs are largely impervious to vibration because they do not have filaments or glass enclosures. LED’s inherent vibration resistance may be beneficial in applications such as transportation (planes, trains, automobiles), lighting on and near industrial equipment, elevators and escalators, and ceiling fan light kits.
4. Rapid Cycling

Traditional light sources will burn out sooner if switched on and off frequently. LED life and lumen maintenance is unaffected by rapid cycling. In addition to flashing light displays, this rapid cycling capability makes LEDs well-suited to use with occupancy sensors or daylight sensors
5. Instant On

LEDs come on at full brightness almost instantly, with no re-strike delay. This characteristic of LEDs is notable in vehicle brake lights, where they come on 170 to 200 milliseconds faster than standard incandescent lamps, providing an estimated 19 feet of additional stopping distance at highway speeds (65 mph). In general illumination applications, instant on can be desirable for safety and convenience.

6. Cold Temperature Operation

LED performance inherently increases as operating temperatures drop. This makes LEDs a natural fit for grocery store refrigerated and freezer cases, cold storage facilities, and outdoor applications. In fact, DOE testing of an LED refrigerated case light measured 5% higher efficacy at -5°C, compared to operation at 25°C.

7. Controllability and Tunability

LEDs may action abeyant allowances in agreement of authoritative ablaze levels (dimming) and blush appearance. However, not all LED accessories are accordant with all dimmers, so architect guidelines should be followed. As LED disciplinarian and ascendancy technology continues to evolve, this is accepted to be an breadth of abundant addition in lighting. Dimming, blush control, and affiliation with control and photoelectric controls action abeyant for added activity ability and user satisfaction.

8. No Bittersweet or Ultraviolet Emissions

Incandescent lamps catechumen a lot of of the ability they draw into bittersweet (IR) or broadcast heat; beneath than 10% of the ability they use is in fact adapted to arresting light. Fluorescent lamps catechumen a college admeasurement of ability into arresting light, about 20%. High acuteness Discharge (HID) lamps can afford cogent ultraviolet radiation (UV), acute appropriate careful and diffusing to abstain addressee exposure. LEDs afford around no IR or UV. Excessive calefaction (IR) from lighting presents a bake hazard to humans and materials. UV is acutely damaging to artwork, artifacts, and fabrics, and can could cause derma and eye burns in humans apparent to defenseless sources.

Ok, that’s all. Have you got the point? LEDs are all that you just want.
