LED light­ing in the health­care in­dus­try: Mov­ing to­wards a greener fu­ture

Electronics Bazaar - - Contents -

In the health­care in­dus­try, elec­tric­ity is used 24x7. Hos­pi­tals are the sec­ond largest en­ergy con­sumers as well as pro­duc­ers of green­house gases. LEDs are to­day the pre­ferred light­ing choice at hos­pi­tals across the world, and this has helped them lower their car­bon foot­print and en­ergy bills by in­cor­po­rat­ing green de­signs.

LED man­u­fac­tur­ers of­fer a wide range of so­lu­tions, which are tai­lored to meet the re­quire­ments of the health­care sec­tor. LED light­ing so­lu­tions can be used in pa­tients’ rooms, wait­ing ar­eas, lob­bies, etc. The ben­e­fits in­clude low main­te­nance, en­ergy ef­fi­ciency and the fact that the tech­nol­ogy en­ables the de­vel­op­ment of prod­ucts with very spe­cific func­tion­al­i­ties. LEDs help to main­tain light lev­els for crit­i­cal vis­ual tasks, like in the op­er­at­ing theatre.

Lat­est trends

The lat­est trend and the most im­por­tant use of LED light­ing is in MRI and CT scan rooms. Apart from that, LED fixtures are be­ing used for gen­eral light­ing in hos­pi­tals.

The three lat­est trends in the health­care sec­tor with re­spect to LED light­ing are:

• Dis­play sig­nage, which is used to cre­ate a pleas­ant am­bi­ence for bedrid­den pa­tients.

• Blue LEDs, which are used to cure that new­born ba­bies are some­times af­flicted with—the tech­nol­ogy used in D-Rev’s Bril­liance de­vice.

• High-bright­ness LED strips with spe­cial colour tem­per­a­tures that are used for X-ray view­ing ma­chines.

Ben­e­fits of LEDs in hos­pi­tals

• Sealed LED light­ing units pro­tect harm­ful bac­te­ria from spread­ing in the hospi­tal. The fully-sealed units pre­vent dust, deadly bugs and harm­ful bac­te­ria from col­lect­ing around the light fit­tings.

• LED lights are safe for MRIs be­cause they do not use met­als that are af­fected by mag­netic fields, nor do they emit ra­dio fre­quen­cies. LED tubes and bulbs are dimmable, mak­ing them ideal for CT scan and ul­tra­sound rooms, where dim­ming may be re­quired for bet­ter ob­ser­va­tion and pa­tient com­fort.

• The longer life spans of LED lights mean lower main­te­nance. And qual­ity LED light­ing has an over­all pos­i­tive ef­fect on pro­duc­tiv­ity and health.

A few ap­pli­ca­tion ar­eas

There isn’t too much of spe­cial­i­sa­tion or a dif­fer­ent range of prod­ucts specif­i­cally de­signed for the health­care sec­tor. The same prod­ucts and so­lu­tions used for any other in­door light­ing re­quire­ment are used in the health­care sec­tor too, though the ap­pli­ca­tion may be dif­fer­ent. A few ap­pli­ca­tion ar­eas are:

• En­doscopy light­ing

• Nail cur­ing

• Mi­croscopy light­ing

• Sur­gi­cal head­lights

• Sur­gi­cal and ex­am­i­na­tion light­ing

• Med­i­cal anal­y­sis

• Biliru­bin ther­apy

• Light­ing for den­tal treat­ment

• Well­ness and ther­apy light­ing

What In­dian play­ers are of­fer­ing

LED man­u­fac­tur­ers are of­fer­ing a wide range of so­lu­tions tai­lored to meet the re­quire­ments of the health­care sec­tor.

Cree TrueWhite tech­nol­ogy de­liv­ers clean, bright light and ac­cu­rate colour to as­sist in di­ag­no­sis, treat­ment and in cre­at­ing a tran­quil en­vi­ron­ment. Cree lu­mi­naires re­quire vir­tu­ally no main­te­nance for decades, and cut en­ergy costs by as much as 80 per cent.

Philips Light­ing sup­ports the health­care sec­tor by re­duc­ing the com­plex­ity of so­lu­tion im­ple­men­ta­tions. It of­fers health­care LED light­ing so­lu­tions that are of high qual­ity and have a high im­pact, lead­ing to en­hanced heal­ing en­vi­ron­ments with min­i­mum has­sle and risk.

Philips of­fers light­ing so­lu­tions called HealWell, which are suit­able for the pa­tient rooms as they take care of the hu­man body’s nat­u­ral re­sponses to light. This light­ing so­lu­tion sim­u­lates sun­light in­doors, al­low­ing pa­tients to main­tain their biorhythm and en­hanc­ing their sense of com­fort and well be­ing.

GE Light­ing of­fers the lat­est tech­nol­ogy for the health­care sec­tor, in­creas­ing light­ing qual­ity and cut­ting down elec­tric­ity bills sig­nif­i­cantly. GE lamps and high ef­fi­ciency bal­lasts of­fer a long and re­li­able life, plus ex­cel­lent lu­men main­te­nance.

NTL Lem­nis of­fers a range of LED light­ing prod­ucts un­der the Pharox brand. Its Pharox ceil­ing lights, Pharox down­lights and LED tube­lights have been in­tro­duced spe­cially to meet the re­quire­ments of the health­care sec­tor.

Pre­mium Light­ing So­lu­tions’ LED tech­nolo­gies are suit­able for the health­care sec­tor as they help de­liver high qual­ity light at re­duced run­ning costs. This is achieved by com­bin­ing lu­mi­naire de­sign with in­tel­li­gent sen­sor con­trols, which smartly turn fit­tings on and off (or dim them down) when there are no peo­ple present or if there is a cer­tain level of am­bi­ent day­light.

Fea­tures to look for in LED prod­ucts that are used in hos­pi­tals

Listed be­low are some fea­tures that hos­pi­tals should look for when us­ing LED prod­ucts.

Ceil­ing mounted LED sur­gi­cal lamps: These should have mul­ti­ple arms and be fit­ted with a video cam­era along with a con­trol panel. They should be dust-re­sis­tant, dirtand liq­uid-re­sis­tant, and must not gen­er­ate heat around the sur­geon’s head and around the wound area of the pa­tient.

Back-lit LED in­te­grated op­er­a­tion room dis­play: This dis­play should be fit­ted with en­do­scopic cam­eras, ul­tra­sound car­di­ol­ogy, pa­tient’s vi­tal signs dis­play and must have a multi-touch screen. It should have clin­i­cal grey scale and colour re­pro­duc­tions, and the screen size should be large enough.

Built-in LED light­ing: This should be well-fit­ted into the re­cesses in ceil­ings or in the wall and should have a high-ef­fi­ciency light dif­fuser. By us­ing vari­able in­ten­sity (VI) tech­nol­ogy, the in­ten­sity of light can be ad­justed to meet var­i­ous ap­pli­ca­tion needs.

Flex­i­ble ex­am­i­na­tion LED lamp: This lamp can be used uni­ver­sally – stand­ing on the floor, mounted on walls and ceil­ings, mounted on a roller stand or in mo­bile mode. It must be ad­justable with re­spect to height and the an­gles it can be placed at. And it should have a high lu­mi­nos­ity (40000lx or more at 5m).

What the fu­ture holds

Ac­cord­ing to an Equen­tis Cap­i­tal re­port, the In­dian health­care in­dus­try is ex­pected to reach US$ 158.2 bil­lion in 2017, as it is grow­ing at a CAGR of 15 per cent, hav­ing jumped from US$ 45 bil­lion in 2008 to US$ 78.6 bil­lion in 2012. So there is bound to be a huge de­mand for en­ergy-ef­fi­cient, in­no­va­tive LED light­ing in this sec­tor.
