Description
Technical field
The invention relates to a kind of projection light fixture, be meant the light fixture of a kind of tool caution, increase security, direction indication and lifting atmosphere especially.
Background technology
Since 19th-century, after Edison invented electric light, light fixture had been indispensable necessity in life;; Along with society and scientific and technological progress, people no longer are to have only illumination to the demand of light fixture, also need other function; To provide people on arround the life, can deal with precipitate situation, enumerate following example:
1. with the car example: usually hear the passenger's desire driving student car on driving or the car; By the news of back car because of dodging and colliding not as good as directly; Moreover, also often run into when being driven in parking or reversing, grab inaccurate bumping because of angle easily; Though there is radar for backing car auxiliary, be unpredictable but have the place, dead angle;
2. be example with the escape lamp: existing escape lamp, when running into the emergency outage, just can open, and also be only to supply illumination; If run into fire, full of smoke, when visibility is very low; The usefulness of its illumination subtracts, and adds people when running into disaster, can flurriedly be at a loss unavoidably; Cause correctly to judge escape direction,, incur loss through delay the time of escape easily if there is not the indication of escape;
3. be example with the street lamp: when late at night, the every household rest of all turning off the light, only remaining street lighting on the streets and lanes; But the illumination of street lamp has only the part, and shady place is still arranged, and the people who returns night is not if one is noted; Possibly will bump against barrier or the low-lying area beyond the road surface of dropping, all too is dangerous.
Therefore, how designing a kind of the present invention who has caution, increases security and direction indication, is the big problem for this case solution that the inventor desires most ardently.
Summary of the invention
One of the object of the invention is to provide a kind of projection light fixture, and the specific combination design through plate body, light source and housing is applied to the guiding of vehicle; Reaching caution, to increase the effect of security, and be applied to the guiding of disaster escape, to reach the effect of indication escaping direction; Be applied to street lamp again, in order to define the border on road surface, to reach the effect of caution and increase security; At last; Except having caution, increasing security and the direction indication, also can be arranged on the communication place, to reach the lifting atmosphere effect.
Two of the object of the invention is to provide a kind of projection light fixture, through the particular design of plate body, makes the little plate body of volume can throw required figure, and the performance maximum effect is to reach the effect of saving the space and reducing cost.
For reaching above-mentioned purpose, the present invention provides a kind of projection light fixture, comprising: first kind of projection light fixture comprises: a plate body, and this plate body is provided with a plurality of grooves, and this groove space is provided with; And a light source, be equipped on a side of this plate body and be projeced on the plate face of this plate body.
