Abstract

The utility model provides a two grades of street lamps of strong and weak light of radar response comprises low light level lamp, strong light, radar inductive switch, circuit, and is parallelly connected with low light level lamp again after adopting strong light and radar inductive switch to establish ties, makes the radar switch can open strong light, and nobody or object provide light more weak base light by low light level lamp when the street lamp scope moves, when someone or thing are movable, provide normal lighting, adopted the utility model discloses a large amount of electric energy can be practiced thrift to the scheme, can satisfy the actual need again simultaneously.

Description

Strong and weak light two grades of street lamps responded to by a kind of radar

Technical field

The utility model relates to a kind of two grades of street lamps, especially uses radar inductive switch to control the street lamp of the major light of street lamp.

Background technology

At present, we are provided with street lamp in streets and lanes, in city, the street street lamp in cities and towns generally adopts time control, i.e. switch lamp on time, also have and adopt light-operated, but these two kinds of control modes do not save electricity, after such as at 12 in a lot of streets and lanes general evening, with regard to few people's walking, street lamp is always bright to daybreak, wastes much electricity.

Utility model content

In order to overcome the shortcoming of existing street lamp waste electricity, the utility model proposes a kind of radar and respond to strong and weak light two grades of street lamps with head it off, its good effect is: have employed a kind of radar and respond to strong and weak light two grades of street lamps, can when unmanned and car move, the base lighting that street lamp only provides light more weak, when having people or object moves in street lamp scope, provide normal illumination, which can save a large amount of electric energy.

The utility model solves the technical scheme that its technical problem adopts: strong and weak light two grades of street lamps responded to by a kind of radar of the present utility model, be made up of weak light lamp, major light, radar inductive switch, circuit, in parallel with weak light lamp again after adopting major light to connect with radar inductive switch, radar inductive switch is made to open major light, nobody or object, when street lamp scope moves, provide base lighting by weak light lamp.

The technical solution adopted in the utility model will coordinate accompanying drawing to elaborate in a particular embodiment.

Accompanying drawing explanation

Here is brief description of drawings.

Fig. 1 is that strong and weak light two grades of lamp post structure schematic diagrames responded to by a kind of radar of the present utility model.

1. switches, 2. weak light lamp, 3. major light in figure, 4. radar inductive switch, 5. circuit, 6. power supply.

Embodiment

In the embodiment in figure 1, we respond to strong and weak light two grades of street lamps further illustrate the utility model to implement a kind of radar:

Fig. 1 is that strong and weak light two grades of street lamp schematic diagrames responded to by a kind of radar of the present utility model, figure breaker in middle 1 is exactly time switch, light-operated switch, for simplicity, draw a regular tap in figure to represent, weak light lamp 2 is exactly the more weak lamp of a kind of light, common energy-saving lamp or LED electricity-saving lamp can be used, major light 3 is lamps that in street lamp, light is stronger, common energy-saving lamp or LED can be used, if will LED be adopted, weak light lamp 2 and major light 3 can also share lamp pearl, adopt the electric current difference flow through in lamp pearl to the shelves that tell the men from the boys; Radar inductive switch 4 is sold there being product on the market, can directly use by buy product, radar switch 4 in figure is the normal opened contact of the relay of radar switch in fact, when the microwave sounding that radar switch sends is to when having a mobile object, its normal opened contact closes, realize switch object, radar inductive switch 4 is in parallel with weak light lamp 2 again after connecting with major light 3.Circuit 5 is exactly plain conductor, for connecting street lamp and road lamp power supply 6 and switch 1, when specifically making, weak light lamp 2, major light 3, radar inductive switch 4 are contained in casing of street lamp together, preferably adopt LED to make weak light lamp 2 and major light 3, so both economize on electricity also long-lived, how the power supply as LED connects, these are all mature technologies, no longer describe in detail.

For the situation of switch 1 time switch, in use, time arrives set point, switch 1 closes automatically, weak light lamp 2 is lighted, base lighting is provided, light is more weak, but can see, when having people or mobile object around lamp, radar inductive switch 4 closes, major light 3 is lighted and delay-action, if mobiles is always movable around street lamp, then weak light lamp 2 is all bright with major light 3, when mobiles is not in street lamp scope, after major light 3 postpones a period of time (being generally about 1 minute), automatic distinguishing, weak light lamp 2 is only had to provide base lighting, due to people and the car activity time shorter, the basic no one of long time or car activity after midnight, so lamp post structure of the present utility model can save a lot of electricity, the illumination provided when having people movable compared with high light line can be provided again simultaneously.

Claims (1)

1. strong and weak light two grades of street lamps responded to by radar, be made up of, it is characterized in that: major light (3) is in parallel with weak light lamp (2) again after connecting with radar inductive switch (4) weak light lamp (2) and major light (3), radar inductive switch (4), circuit (5).
