Abstract
An automatic control circuit of an outdoor lighting system is connected with an LED lamp circuit. The automatic control circuit is characterized by comprising a relay, an optical control IC (integrated circuit), a transformer and a rectifying filter capacitor C1, which are connected with the LED lamp to form a loop, the transformer provides power to the optical control IC and allows the commercial power to subject to a voltage reduced process, a first pin of the input end of the optical control IC is connected with the positive terminal of the power supply, a second pin of the input end of the optical control IC serves as a gating end, and a fourth pin of the output end of the optical control IC is controlled by a level at the gating end. The automatic control circuit has the benefits that the open or close of the lighting equipment is controlled according to the natural lighting change of the environment at the moment without requiring manual control, and the sensitiveness to lights can be adjusted.
Description
[technical field]
The utility model relates to lighting field, relates in particular to the control circuit to exterior illumination system.
[background technology]
The big city needs the lighting in large stretch of scope, wide field night, and lighting apparatus is the colleague that night, life was provided convenience, wasted a large amount of electric energy, the system that has passes through setting-up time, light and close according to the standard time, but, have the phenomenon of energy waste because illumination condition throughout the year is different, if lighting hours can occur accurately to control, so need control exterior illumination system by the circuit of a precise design and manually operate.
[summary of the invention]
The utility model has proposed a kind ofly to have auto-switch function, not influenced by seasonal climate, control circuit easy for installation at above problem.
The technical solution of the utility model is: related exterior illumination system automatic control circuit, be connected with the LED light fixture, it is characterized in that, comprise with the LED light fixture and connect and compose the relay in loop, light-operated IC, civil power carried out transformer and the rectifying and wave-filtering capacitor C 1 that step-down is handled to light-operated IC power supply, wherein light-operated IC input first stitch is received power positive end, and second stitch is the gating end, and output the 4th stitch of light-operated IC is controlled by gating end level.
Described lamp circuit comprises rectifier bridge, filter capacitor, the drive controlling IC of electrical connection.
Wherein two circuits in the second stitch place of light-operated IC have inserted resistance R 5 and R4 respectively, and resistance R 5 is subjected to natural light irradiation to present low resistance, and this moment, gating end second stitch was a high level; And R4 presents high resistance under no natural light irradiation, and this moment, gating end second stitch was a low level.
Also comprise the resistance R 5 that to regulate light-operated sensitivity in the described automatic control circuit.
The beneficial effects of the utility model are: can change the switching of controlling lighting apparatus according to the natural illumination of environment of living at that time, not need Artificial Control, and can regulate the susceptibility to light.
[description of drawings]
Fig. 1 is the utility model one embodiment circuit theory diagrams.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: related exterior illumination system automatic control circuit, be connected with the LED light fixture, it is characterized in that, comprise with the LED light fixture and connect and compose the relay in loop, light-operated IC, civil power carried out transformer and the rectifying and wave-filtering capacitor C 1 that step-down is handled to light-operated IC power supply, wherein light-operated IC input first stitch is received power positive end, and second stitch is the gating end, and output the 4th stitch of light-operated IC is controlled by gating end level.
Described lamp circuit comprises rectifier bridge, filter capacitor, the drive controlling IC of electrical connection.
Wherein two circuits in the second stitch place of light-operated IC have inserted resistance R 5 and R4 respectively, and resistance R 5 is subjected to natural light irradiation to present low resistance, and this moment, gating end second stitch was a high level; And R4 presents high resistance under no natural light irradiation, and this moment, gating end second stitch was a low level.
