Marker lights for wireless doorbell transmitters and similar devices |
| abstract |
A marker luminaire (10) combines a super bright LED (22) and an electrical drive circuit (16) operable in a low current mode to promote long battery (26) life. The luminaire (10) comprises a housing (12) with the super bright LED (22) disposed in the housing so that low level light visible to a partially darkness adapted human eye is visible from outside the housing. A minimal current is selected to produce enough light to be seen at the desired distances. A light scattering element (30) is optically associated with the LED (22) to make the marker luminaire (10) visible across a wide viewing angle. The electrical drive circuit (16) may further comprise a photosensitive element (24) responsive to high and low ambient light conditions for cycling operation of the LED. A replaceable electrical power cell (26) provides a power source for the electrical drive circuit (16). |
