Embodiment Construction

[0009] The present invention will be described below in conjunction with the embodiments and the accompanying drawings.

[0010] See figure 1 with figure 2 , A low-consumption smart solar lawn lamp, comprising a solar battery UT, a battery E, a light-emitting diode LED as a light source, and a controller. The controller is equipped with a control circuit on the circuit board. The control circuit has an optocoupler IC1. Pin 1 and pin 2 of the optocoupler IC1 are connected to the two ends of the solar cell UT.

[0011] See figure 1 , Pin 3 of optocoupler IC1 is connected to pin 2 and pin 6 of time base integrated circuit IC2. Time base integrated circuit IC2 is used. When pin 3 (output end) of optocoupler IC1 is at high level, time base integrated circuit IC2 outputs a light-on signal; when pin 3 (output end) of optocoupler IC1 is at low level, time base integrated Circuit IC2 outputs a light-off signal. The time-base integrated circuit IC2 has the advantages of strong driving abi...

Abstract

The disclosed light fitting includes solar battery, accumulator, light emitting diode, and controller. The controller sets up control circuit including an optical couple element on circuit board. First pin and second pin of the said optical couple element are connected to two ends of the solar battery respectively. At evening, voltage of the solar battery becomes lower from higher, and output resistance value of the optical couple element becomes larger from smaller; at morning, voltage of the solar battery becomes higher from lower, and output resistance value of the optical couple element becomes smaller from larger. Variety of output resistance magnitude of optical couple element is adopted to distinguish day and night without lighting window so as to simplify circuit and reduce no load loss greatly.

Description

1. Technical field [0001] The invention relates to a solar lamp, in particular to a solar lawn lamp. 2. Background technology [0002] Solar lawn lights are widely used because of their compliance with environmental protection requirements and their superior safety performance, and their demand will become greater and greater. Unlike the lawn lights powered by city electricity, solar lawn lights can be controlled centrally, but must be controlled separately. A Chinese patent once disclosed "a solar lawn lamp control circuit" (ZL032207204, CN2612203Y, announcement date: April 14, 2004). The boost circuit in the control circuit is an L and C oscillating boost circuit, and the inductor L In order to close the magnetic circuit inductance coil; in the control circuit, the input end of the controller is connected to the solar cell and the storage battery, the output end of the controller is connected to the oscillating booster circuit, and the output of the oscillating b...
