Indian Standard SPECIFICATION FOR


PART ti STANDARD LAMP DATA SHEETS

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 23 September 1981, after the draft finalized by the Electric Lamps and Accessories Sectional Committee had been approved by the Electrotechnical Division Council.

0.2 This standard ( Part II ) has been prepared to cover electrical characteristics for lamps starting and operation of high pressure sodium vapour lamps. Additional information for purposes of design of ballast, luminaires and ignitors, where essential, have also been incorporated. It is hoped that at a later stage ‘it shall be possible to prepare a more detailed standard which will state requirements necessary for safety together with test conditions and procedures for complete testing of these lamps.

0.3 This standard~consists of the following two parts:

Part I General requirements and tests; and

Part II Standard lamp data sheets.

0.3.1 This standard shall be read in conjunction with Part I of this standard.

0.4 In the preparation of this standard ( Part II ) assistance has been derived from IEC Pub-662 ( 1980 ) High pressure sodium vapour lamps, issued by the International Electrotechnical Commission.

0.5 The life expectancy and nominal lumen output of high pressure sodium vapour lamps are under consideration by the committee and would be added at a later date as and when sufficient data are available, However, for the purpose of guidance, the nominal life of such lamps may be taken as 5 000 -hours.

0.6 For the purpose of deciding whether a particularrequirement of this standard is complied with, the final value, observed or calculated, expressing

3

IS : 9974 ( Part II ) - 1981 ,

the result of a test. shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard ( Part II ) comprises lamp data sheets for high pressure sodium vapour lamps covered -by this standard.

2. TERMINOLOGY

2.1 For the purpose of this standard, the definitions given in IS : 9974 (Part I )-19817 shall apply.

3. &ECOMMENDED LAhlP TYPES

3.1 The recommended types of high pressure sodium vapour lamps covered by this standard are as follows:

a) 150 W Tubular clear,

b) 150 W Elliptical.- diffuse coating,

c) 250 W Tubular clear,

d) 250 W Elliptical - diffuse coating,

e) 400 W Tubular clear, and

f) 400 W Elliptical - diffuse coating.

4. LAMP DIMENSIONS CAP AND OTHER DETAILS

4.1 The overall lamp dimensions, bulb diameter and type of caps that are to be employed in the lamp shall be asgiven in the relevant data sheet. Sche- matic ‘drawings for location of lamp dimensions specified in the data sheets have been indicated in Fig. 1 and 2.

Norx - There are two designs of lamp presently in use which are compati- ble in operation, but which require different starting conditions.

Some lamp designs require a minimum pulse height of 1 600 V whereas other designs require a minimum pulse height of 1 800 V. Illformation is to be provided by the lamp manufacturer as to,which ignitor pulse height and width are appropriate.

For future starting compatibility of both lamp types, it is recommended that ignitors are designed with a minimum pulse height of 1.800 V.
