The

and

With

the

appropriate

socket

you

can

Interchange

between

Hg,

Xe,

and

Hg(Xe)

lamps

of

different

power.

An

ignitor

is

built

into

the

top

of

the

lamp

hous-

ing.

This

reduces

RF

interference,

and

eliminates

the

need

for

a

stand

ignitor.

These

lamp

are

designed

to

operate

with

Oriel

Supplies.

SAFETY CONSIDERATIONS

Summary

of

Hazards

II

66000·M

UNIVERSALARC LAMP HOUSING

There

are

six

hazards

in

the

operation

of

systems

employing

these

lamp

housings.

They

are:

Radiation

Lamp

Explosion

Ozone

Electrical

Shock

EMI

Heat

The

interlock

system

is

designed

for

your

safety.

Do

not

defeat

the

interlocks.

II.1

RADIATION

The

high

Intensity

UV

radiation

of

these

lamps

can

permanently

damage

the

cornea,

lens,

and

retina

of

the

eye,

even

causing

blindness.

This

damage

may

not

be

Imme-

diately

apparent.

The

deep

UV

is

absorbed

in

the

cornea

or

eye

fluids;

focused

UV,

VIS

and

NIR

can

damage

the

retina.

Normal

blink

reaction

to

visible

light

may

not

be

adequate

protection,

and

a

beam

of

invisible

UV

or

NIR

(produced

by

spectral

filter-

ing)

can

be

most

dangerous

as

the

blink

response

is

not

Induced.

UV

radiation

can

also

cause

painful

sunburn,

and

with

prolonged

exposure,

serious

burns.

Recommendations:

1

Never

look

directly

into

the

output

beam

of

a

housing

when

operating

a

lamp.

2 Never

look

at

a

specular

(mirror)

reflection

of

the

beam,

even

for

short

periods

of

time.

3

Use

the

interlock

system

to

prevent

access

to

a

working

lamp.

4

Always

wear

UV

safety

eyewear

or

facemask,

and

protective

clothing

for

exposed

areas

of

skin.

II.2

LAMP

EXPLOSION

When

cold,

xenon

and

mercury(xenon)

arc

lamps

are

under

several

atmospheres

of

pressure

and

are

subject

to

explosion

due

to

internal

strains

or

to

physical

abuse.

When

hot,

all

lamps

are

under

a

pressure

of

close

to

100

atmospheres

and

subject

to

violent

explosion.

5

Recommendations:

66000-M

UNIVERSAL ARC LAMP

HOUSING

1

Do

not

handle

a

bare

arc

lamp

without

safety

goggles

and

adequate

protection

for

exposed

areas

of

skin.

2

Do

not

apply

torque

to

the

lamp

envelope

during

installation

or

removal.

3

Do

not

touch

the

lamp

envelope.

Fingerprints

and

other

contaminations

left

on

.

the

lamp

cause

a

deterioration

of

the

envelope

during

operation

and

may

lead

to

lamp

explosion.

4

Thoroughly

clean

the

envelope

with

alcohol

or

a

dilute

solution

of

detergent

and

water

after

Installation

in

the

housing.

5

.Cover

the

aperture

of

the

housings

without

condensers,

before

operation.

II.3 OZONE

Shortwave

ultraviolet light

photolyzes

oxygen

to

produce

ozone.

This

is

emitted

in

the

cooling

air

stream

of

the

lamp

housing.There

is

no

simple

way

of

predicting

the

ozone

concentration

(or

its

Impact

on

you)

e.g.,

operation

in

a

small

enclosed

area

may

lead

to

high

concentrations.

Operation

of

the

same

system

in

a

large,

well

ventilated

laboratory

may

not

be

a

problem.

Recommended

maximum

expo-

sures

are

typically:

0.1

ppm

for

8

hours

exposure

2

ppm

for

a 2

hour

exposure

A

very

sensitive

nose

can

detect

0.015

ppm.

1

ppm

produces

a

strong

and

obnox-

Ious

odor.

As

a

rule

of

thumb,

if

you

can

easily

smell

ozone,

the

level

is

too

high

for

prolonged

exposure.

Recommendations:

1

Use

an

ozone

free

lamp

unless

you

need

the

shortwave

UV.

2

Operate

the

system

in

a

large

ventilated

area.

3

Use

an

Ozone

Eater™,

found

in

our

Volume

II

catalog.

IlA ELECTRICAL SHOCK

A

high

(>20kV)

transitory

voltage

is

used

to

ignite

the

lamp.

Lamp

current

is

up

to

22

amperes.

Additionally,

line

voltage

is

supplied

to

the

housing

to

power

the

fan

and

elapsed

timer.

This

line

voltage

will

stili

be

present

even

when

the

power

sup-

ply

is

disconnected

from

the

housing.

Recommendations:

1

Keep

of

all

exposed

terminals.

66000-M

UNIVERSAL

ARC

LAMP

HOUSING

2

,Before

relamping

or

working

on

the

system,

disconnect

the

Input

power

to

the

lamp

housing

from

the

line,

turn

off

the

power

supply

and

check

the

power

supply

voltmeter

for

zero

voltage

to

be

sure

that

Internal

capacitors

are

fully

discharged.

3

Make

sure

all

connections

are

securely

made

(and

check

the

polarity)

before

starting

a

lamp.

4

Do

not

handle

the

lamp

leads

during

lamp

ignition.

Ignition

of

an

arc

lamp

requires

high

voltage

high

frequency

(1

OO's

of

kHz)

pulses.

A

high

current

dump

(kHz

discharge)

follows.

Both

of

these

are

sources

of

electromagnetic

interference,

both

radiated

and

conducted.

Good

earthing

and

cable

routing

practice,

and

EMI

shielding

may

be

necessary

to

protect

sensitive

digital circuitry

from

these

pulses.

Recommendations:

1 Start

the

arc

lamp

before

powering

nearby

computer

systems.

2

Keep

the

computer

at

least

6

feet

away

from

the

Ignitor/power

supply.

3

Use

adifferent

outlet

and

line

for

the

computer

and

ignitor/power

supply.

II.6 HEAT

Arc

lamps

become

very

hot

after

only

minutes

of

operation,

and

remain

very

hot

for

up

to

10

minutes

after

being

shut

off.

Recommendations:

1

Do

not

touch

the

lamp

with

your

bare

hands

for

at

least

10

minutes

after

being

shut

off.

GENERAL DESCRIPTION

66000·M

UNIVERSAL

ARC

LAMP HOUSING

These

lamp

housings

are

lightweight

but

rugged.

They

are

excellent

choices

for

most

low

to

medium

power

laboratory

lamps.

You

can

mount

them

to

optical

tables,

rails,

or

benches.

Various

models

with

different

condensers

are

available.

With

the

complete

line

of

optical

accessories

described

in

Volume

II,

you

can

filter,

focus,

and

steer

the

output

to

fit

your

application.

Both

types

of

lamp

housings

described

in

this

manual

(50

to

250

Wand

200

to

500

W),

use

the

same

shell.

The

200

to

500

W

models

have

a

more

powerful

fan

to

en-

sure

correct

operating

conditions

for

the

higher

wattage

lamps,

and

adifferent

mount-

Ing

block

to

accept

the

larger

lamps.

III.I

LAMP

AND

REFLECTOR

ADJUSTMENTS

The

position

of

the

arc

(relative

to

the

terminals

which

secure

the

lamp)

varies

slightly

from

lamp

to

lamp.

This

is

because

of

normal

arc

lamp

manufacturing

tol-

erances.

These

lamp

housings

have

adjustments

to

place

the

arc

of

a

new

lamp

in

the

same

position

as

that

of

the

lamp

being

replaced.

Three

fine

controls

posi-

tion

the

reflector.

Then,

Independent

tilt

controls

position

the

arc

horizontally

and

vertically.

The

reflector

and

its

controls

travel

with

the

vertical

and

horizontal

con-

trols.

This

eliminates

the

need

for

Iterative

lamp-reflector

adjustments.

See

Fig.

1

on

page

10

for

location

of

adjusters.

III.2

BUlL

T·IN IGNITOR

The

housings

described

In

this

manual

have

an

ignitor built

into

the

top

of

the

housing.

Short

arc

lamps

require

a

high

voltage

spike,

up

to

40

kV

for

xe

lamps,

to

ignite.

Having

the

ignitor built

into

the

lamp

housing

minimizes

unwanted

radi-

ated

or

conducted

RFI.

III.3

LAMP

COOLING

The

built

in

fan

and

housing

baffles

ma.intain

the

proper

operating

temperature

for

arc

lamps,

when

operated

In

normal

laboratory

ambient.

Overheating

due

to

blocking

of

the

cooling

vents

or

an

Inoperative

fan,

activates

a

thermostat

Inter-

lock.

The

cooling

fan

can

be

operated

on

110

or

220

volts

AC

line.

The

housings

have

an

AC

connector

which

is

designed

to

accept

U.S.

style

power

cords.

The

hous-

ings

are

supplied

with

a

power

cord.

If

the

power

cord

is

not

compatible

with

your

wall

socket,

replace

the

plug

at

the

end

of

the

power

cord.

Check

that

the

line

se·

lect

switch

(below

the

fan)

is

In

the

appropriate

110/220

V

position

before

plug-

ging
