摘要： A solar powered light adapted to be mounted under the eaves of a building, a wall or the like for use in security applications. In a preferred embodiment of the present invention, the solar powered light comprises an adjustable configuration having a lamp with an infrared detector or sensor rotatably mounted thereto and a photovoltaic or solar cell array rotatably disposed at a remote end of an extension arm movably attached to the lamp. Such a flexible arrangement allows the photovoltaic array to be positioned to receive direct sunlight. The sensor activates the solar powered light upon sensing infrared to illuminate the surrounding areas when a presence is sensed and turn it off when a presence is no longer sensed. In accordance with a second embodiment, the solar powered light does not include an infrared detector and provides continuous illumination for a given period of time. In accordance with a third embodiment, the solar powered light does not include an infrared detector, but includes a battery having a higher capacity configured to provide illumination for extended periods of time. In accordance with a fourth embodiment, the solar powered light is configured to be used directly with a user's battery. The solar powered light utilizes a compact fluorescent bulb and circuitry for providing longer lamp life, instantaneous illumination and eliminating flickering during start up.
摘要翻译： 一种适用于安装在建筑物，墙壁等的屋檐下的太阳能光源，用于安全应用。 在本发明的一个优选实施例中，太阳能光源包括具有可旋转地安装在其上的红外检测器或传感器的灯的可调配置，以及可旋转地设置在延伸臂的远端处的光伏或太阳能电池阵列，可移动地连接到 灯。 这种灵活的布置允许光伏阵列被定位以接收直射的阳光。 感测红外线时，传感器激活太阳能供电的光线，以便在感测到存在时照亮周围区域，并在不再感测到存在时将其关闭。 根据第二实施例，太阳能光源不包括红外检测器并且在给定的时间段内提供连续照明。 根据第三实施例，太阳能光源不包括红外检测器，而是包括具有较高容量的电池，其被配置为在延长的时间段内提供照明。 根据第四实施例，太阳能光被配置为直接与用户的电池一起使用。 太阳能光源采用紧凑型荧光灯泡和电路，以提供更长的灯泡寿命，瞬时照明并消除启动期间的闪烁。

摘要： A solar powered lamp having a circuit for providing positive turn-on at low light levels causes a light source thereof to undergo a discrete transition to an "on" condition and prevents unnecessary drain on a battery thereof. The circuit comprises a positive feedback loop which amplifies current flow rapidly to a predetermined level at which the light source is illuminated. In doing so, it causes a plurality of solar powered lamps to illuminate at substantially the same time.
