I, JOHN MACINTOSH MACKAY MUNRO of 136 Bothwell Street, Glasgow, in
the County of Lanark, North Britain, Electrical Engineer, do hereby declare the
nature of this invention to be as follows:-
In lighting shop windows with the electric light it is necessary for the effective
lighting of the goods in the window that the light be shaded so that it does not
shine directly upon the eyes of parties wishing to inspect the goods while at the
same time, to make windows attractive to passers by, it is desirable to allow the
electric light to throw its rays outward towards the street. This has hitherto been
an impossible accomplishment.
My improvements consist in piercing the lamp shades (which conceal the light
from the eye of the onlooker and reflect it on the goods) with numerous minute
holes or perforations preferably arranged so as to enrich the design of the shade or
reflector. It is found that these holes or perforations do not interfere with the
efficiency of these as shades or reflectors, and while viewed from a distance the
natural sparkle and brilliancy of the electric light is enhanced.
These shades may also be used whenever a similar effect is desirable, as for
example in lighting pictures.
Dated this 10th day of July 1890.

COMPLETE SPECIFICATION.
Improvements in Shades for Electric Lamps for Displaying Goods in
Shop Windows and other places.
I, JOHN MACINTOSH MACKAY MUNRO, of 136 Bothwell Street, Glasgow,
North Britain, Electrical Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In lighting shop windows with the electric light it is necessary for the effective
lighting of the goods in the window that the light be shaded so that it does not
shine directly upon the eyes of parties wishing to inspect the goods, while at the
same time to make windows more attractive to passers by it is desirable to allow
the electric light to throw its rays outwards towards the street. This has hitherto
been an impossible accomplishment.
My improvements consist in piercing the lamp shades (which conceal the light
from the eye of the onlooker and reflect it on the goods) with numerous minute
holes or perforations, usually less than 1, but not exceeding of an inch in
diameter and preferably arranged so as to enrich the design of the shade or reflector.
It is found that these holes or perforations do not interfere with the efficiency of
these as shades or reflectors, and while viewed from a distance the natural sparkle
and brilliancy of the electric light is enchanced.
These shades may also be used whenever a similar effect is desirable, as for
example in lighting pictures.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Small shades or reflectors pierced with numerous minute holes or perforations
not exceeding of an inch in diameter, as and for the purposes hereinbefore
described.
