For achieving the above object, the classroom that the utility model provides comprises fluorescent tube, is fixed on the reflector mainboard on the bottom reflector holder and is arranged at the reflector side plate of both sides with the single tube lighting, it is characterized in that:
Described reflector mainboard invagination is one-body molded, and the reflector mainboard is made up of a plurality of fillets plane, and the cross section of described reflector mainboard is a zhou duicheng tuxing.
Each forms 9 fillet planes respectively through 9 invaginations the both sides of described reflector mainboard.
Described fluorescent tube is arranged at the focus place of reflector mainboard.
Angular range between the described adjacent fillet plane is at 155 °～178 °.
As of the present utility model preferred, the interplanar angle of fillet that the plane, top of reflector mainboard is adjacent is 158.45 °, and 8 adjacent angles of postponing down are followed successively by 162.04 °, 166.06 °, 169.08 °, 173.89 °, 176.50 °, 176.70 °, 175.90 °, 176.40 °.
The scope of the width on described fillet plane is 9mm～20mm.
As optimized technical scheme, the width on the fillet plane adjacent with the plane, top of reflector mainboard is 16.34mm, and the width on the fillet plane down of postponing successively is 10.68mm, 12.43mm, 15.14mm, 9.18mm, 10.76mm, 12.94mm, 15.67mm, 19.62mm.
Width at the bottom of the described reflector mainboard between the edge is preferably 147.32mm, and the height of reflector mainboard is 103.88mm.
As improvement, laterally evenly be provided with shadow shield along described light fixture to technical solutions of the utility model.
The quantity of described shadow shield preferably can be 3,12 or 14.
Described fluorescent tube is the T8 fluorescent tube.
Compared with prior art, the beneficial effects of the utility model are:
1), the distribution curve flux by the utility model reflector mainboard designs, luminaire efficiency of the present utility model is improved greatly, detect luminaire efficiency of the present utility model through China State Light Industry Luminaire Quality Supervision and Inspection Center and reach 76.2%, be higher than the relevant regulations of national standard the classroom light fixture.
2), classroom described in the utility model can not cause unwanted light to distribute on the blackboard metope with the single tube lighting, when electronic teaching, need not close lighting, just can satisfy the vision requirement of student viewing projection screen, simultaneously guaranteed that again light has enough Illumination Distribution on the desk surface, luminous intensity distribution meets the human efficiency subject; And, both satisfied the requirement of audio-visual classroom because the reasonable disposition of shadow shield quantity has reduced dazzle, protected student's eyes and eyesight again effectively.
