A kind of street lampshade with rainy day illumination functions
Technical field
The present invention relates to lighting technical field, and in particular to a kind of street lampshade of band rainy day illumination functions.
Background technology
Street lamp is used for being illuminated road, and the lampshade of street lamp often plays rain cover, sunshade, optically focused, provides the work such as support
With such as Authorization Notice No. discloses a kind of street lampshade for the Chinese invention patent of CN203703828 U, using optical reflection
Away from assembling light, good illumination effect and energy-conserving and environment-protective.
However, in rainy day especially heavy rain weather, weather is dark, the curtain of rain blocks sight line, and road sight line is in poor shape, shadow
The judgement of driver is rung, is easily got into an accident.
Content of the invention
The purpose of the present invention, is to solve the above problems, provides a kind of heavy rain weather and open the road that light source is illuminated
Lamp lampshade.
Technical proposal that the invention solves the above-mentioned problems is as follows:
A kind of street lampshade with rainy day illumination functions, including the lamp shade body of built-in light source, the lamp shade body upper
End offers opening, and the opening lower section is provided with rain-harvesting trough, and the side of the rain-harvesting trough is provided with refracted slot, the rain-harvesting trough
It is connected with the refracted slot, through hole is row's rain passage;The bottom of the refracted slot and the corresponding positions on the lamp shade body top
Install and a pair of infrared sensor is equipped with, the infrared sensor controls the switch of light source by circuit, when the infrared sensor
During mutual UNICOM, the light source is closed, and when the infrared sensor mutually disconnects, the light source is opened.
Used as the preferred of technique scheme, the width of the refracted slot is less than 3mm, and the depth of the refracted slot is more than
35mm.
When rainy, rainwater is flowed in rain-harvesting trough from opening, then is flowed down by row's rain passage of rain-harvesting trough bottom, and flows into folding
Groove is penetrated, when rainfall is sufficiently large, depth of the rainwater in the refracted slot is deeper, then be now placed in the bottom of the refracted slot
The infrared ray launched of infrared sensor be refracted, the infrared sensor positioned at the lamp shade body top is not felt by infrared
The irradiation of line, disconnects equivalent to infrared sensor, receives the signal of infrared sensor by controller, and controls light source so that
Light source is opened, and road is illuminated.
Limit the width of refracted slot and depth be in order in certain rainfall(Rainfall is larger, and road sight line is unintelligible)Situation
Lower ensure ultrared refraction angle, be disconnected a pair of infrared ray sensor;When rainfall is compared with hour, road sight line is fair, folding
Penetrate trough inner water amount few, ultrared refraction angle is not enough, a pair of infrared ray sensor is still in UNICOM's state, and controller receives letter
Number so that light source is not turned on.
Row's rain passage can avoid rain-harvesting trough internal water accumulation.
Used as the preferred of technique scheme, the opening two ends have downward-sloping inclined-plane.
As the preferred of technique scheme, filter screen at the opening, is provided with, the aperture of the filter screen is 1-5mm.
Filter screen prevents debris from entering rain-harvesting trough, blocking refracted slot or row's rain passage.
Used as the preferred of technique scheme, the profile of row's rain passage is identical with the cross section profile of the refracted slot,
I.e. described refracted slot whole UNICOMs in addition to bottom with the contact surface of the rain-harvesting trough.
Used as the preferred of technique scheme, the bottom of the rain-harvesting trough is provided with radiating fin, the radiating fin bottom
End offers permeable hole.
Used as the preferred of technique scheme, the exit of the refracted slot is provided with radiating fin.
Used as the preferred of technique scheme, the refracted slot is connected with the rain-harvesting trough by elastic component, when the folding
When penetrating in groove by rainwater, the gravity of the refracted slot increases, and spring is elongated, and one end of refracted slot moves down, described in a pair
Infrared sensor mutually staggers, and light source is opened, and after rain stops or rain hour, the gravity of the refracted slot diminishes, and spring is by the folding
Penetrate groove to retract, infrared sensor described in a pair is again to upper, light source cut out.
In sum, the invention has the advantages that:
A kind of street lampshade for being suitable to rainy day illumination of the present invention has the advantage that:1. heavy rain weather opens light
Source so that driver has better view;2. perfect heat-dissipating, when raining, light source is opened, and rainwater simultaneously flows through radiating fin and rises
Act on to water-cooled.
