Description
Technical field
The present invention relates to a kind of projection lamp, more particularly to a kind of outdoor road surface projection lamp.
Background technology
With the progress of Optoelectronics Technology, increasing enterprise is publicized using outdoor advertising, is typically used
The mode of projection film or LED screen shows the content of advertisement.Needed during the ad content more renewed every time for projection film
Remake film, need to pull down on old advertisement film during installation, then new film is installed, wasted time and energy,
Need higher cost of labor.For LED screen mode, LED screen is too small not to reach good advertisement function, and LED screen is too
Greatly, early investment cost is again very high.
With the development of shadow casting technique, application is more and more common, and this sound is all configured with many families or office
The device for projecting of light effect.But existing projector equipment is normally applied indoors at present, and need in metope or fixation
Perspective plane on projected.If by existing projector equipment using being projected on road surface out of doors, first, projection is set
Standby degree of protection does not reach requirement, and existing projector equipment is opened wide with external environment, dust out of doors, rainwater etc.
Projecting apparatus is easily damaged under environment, and service life greatly shortens；Secondly, the lighting on road surface can disturb the effect of projection, make
It is unintelligible to obtain projected picture.Under normal circumstances, the picture for being projected in ground is all to be shown by diffusing reflection to human eye, differently
The light just come is the effect being superimposed, so in addition to the light of projection, other light are all distracters, more
Interference light picture can be allowed more unintelligible.
The content of the invention
For above technical problem, the invention provides a kind of outdoor road surface projection lamp, can apply out of doors, on road
Projection is realized on face, and has the function of illumination and projection concurrently, there is clearly projected picture effect, and have the higher longevity
Life.
On the other hand, the technical solution adopted by the present invention is：A kind of outdoor road surface projection lamp, including it is electric power driving module, logical
News and control module, lighting source, projection module and radiating module；

This technical scheme controls the light of illumination and projection by communication and control module output control signal, so as to reach
To removal or weaken interference effect of the illumination to projection.When projection does not work, lighting source normal use；And when projection starts
During work, communication and the electric current driving of control module output switching signal shut-off lighting source so that the ground at projection does not have
The light of light fixture；Further optimize, CPU can also export dim signal by controlling the light of power drives lighting source
Line is dimmed, weakens annoyance level.
Under normal circumstances, it is all by caused by diffusing reflection to human eye that picture on ground is thrown in projection, and different places are come
Light be superposition effect, therefore in addition to the light of projection, other light are all distracters, more interference lights
Picture can be allowed more unintelligible.After both are combined using this technical scheme, interference source can be arbitrarily controlled, allows and projects to road surface
Projection reach optimum efficiency, greatly reduce interference of the illumination to projection, it is not high also to solve projection brightness, it is impossible to be applied to
Outdoor short slab；And the playing function of illumination and projection can realize free switching at any time.
