Lamp
A lamp ( 100 ) having a housing ( 130 ) with a translucent or transparent portion ( 133 ). The housing encloses a light emitting arrangement ( 110 ) and supports a lens ( 120 ) that covers a light exit window ( 131 ) of the housing ( 130 ). The width of the lens is greater than the width of the light exit window. A transmissive (i.e., translucent or transparent) portion ( 133 ) of the housing ( 130 ) is configured to transmit light through to the lens ( 120 ).
1 . A lamp comprising:
a light emitting arrangement configured to emit light;
a lens, configured to receive light emitted by the light emitting arrangement; and
a housing that houses the light emitting arrangement and supports the lens, the housing comprising:
a light exit window through which light emitted by the light emitting arrangement is able to exit the housing, wherein the lens is positioned to cover the light exit window;
an edge bounding the light exit window; and
a transmissive portion adjacent to the edge, the transmissive portion being formed of a transparent and/or translucent material,
wherein the width of the lens is greater than the width of the light exit window,
wherein the transmissive portion and lens are configured and positioned such that at least a portion of light, originally emitted by the light emitting arrangement and incident upon the transmissive portion, is transmitted to the lens.
2 . The lamp of claim 1 wherein the edge of the housing supports the lens to cover the light exit window.
3 . The lamp of claim 2 , wherein the lens comprises a snap-fit arrangement configured to couple to the edge of the housing using a snap-fit mechanism.
4 . The lamp of claim 1 , wherein the transmissive portion of the housing extends the entire way around the edge of the housing.
5 . The lamp of claim 1 , wherein the transmissive portion of the housing includes the edge of the housing.
6 . The lamp of claim 5 , wherein the height of the transmissive portion of the housing, from a point of the edge most distant from the light emitting element towards the light emitting arrangement, is no less than 4 mm.
7 . The lamp of claim 1 , wherein the width of the lens is greater than the sum of the width of the light exit window and two times the thickness of the edge of the housing.
8 . The lamp of claim 1 , wherein the transmissive portion of the housing is formed of a transmissive plastic or glass.
9 . The lamp of claim 8 , wherein the transmissive plastic or glass is transparent.
10 . The lamp of claim 1 , further comprising a reflector, positioned between the light emitting arrangement and the transmissive portion, configured to direct light emitted by the light emitting arrangement towards the light exit window and/the or transmissive portion of the housing.
11 . The lamp of claim 10 , wherein:
the housing is formed of a single material; and
the reflector is a layer of reflective material coated on an inner sidewall of the housing.
12 . The lamp of claim 11 , wherein the reflective material is a specular metal coating or diffusive metal-oxidate coating.
13 . The lamp of any of claims 1 to 12 , configured as a GU-10 or GZ-10 lamp.
14 . The lamp of claim 1 , wherein the light emitting arrangement comprises one or more LEDs.
15 . A lighting fixture comprising the lamp of claim 1 .
