Description
Technical field
The present invention, about a kind of light fixture, refers to that one can have preferably distribution curve flux especially, the bright dipping of fluorescent tube can be made to produce light and concentrate and improve the light fixture of brightness.
Background technology
Press, present Upholstering design is office's Upholstering design particularly, arranges light steel frame ceiling in order to pursue simple usual meeting attractive in appearance at interior space top, and because having the design being easy to dismantle, and pipeline system maintenance within doors can be facilitated, be therefore widely used in various building; Generally speaking, light steel frame ceiling formed with several crisscross T-shaped bar, and be arranged with the framework of several square or rectangular, a pedestal is comprised in framework, and a plurality of fluorescent tube be installed on this pedestal, and in framework, be equipped with a plurality of longitudinal direction and laterally staggered reflecting plate and flase floor, and the two ends of each reflecting plate and flase floor are positioned framework respectively, make fluorescent tube can avoid dropping by flase floor.
During use, the mercury in fluorescent tube is through the evaporation of lamp tube ends filament heating, and form thin mercury vapour, mercury atom discharges ultraviolet light by the process of gas discharge, and ultraviolet excites the fluorescent material be coated on tube wall again, and then sends white light; So, the mercury in fluorescent tube is have contaminative and the heavy metal element to harm, not only makes fluorescent tube be not easy recycling, and easily causes the pollution of environment; Moreover, carbon reduction has become the emphasis of global development trend, countries in the world advocate thriftiness one after another the energy policy, advocate energy-conservation importance, energy-conservation subject under discussion is instantaneous becomes hot fever topic, and relevant governmental office all conducts vigorous propaganda people and will form the custom that Turn Off Lights When Leaving; In recent years, due to the fast development of light emitting diode, and it has that power consumption is low, assembly life-span long, reaction speed is fast, power saving, low stain and the advantage such as volume is little, therefore, along with the lifting of technology, develop the light-emitting diode lamp tube that can replace fluorescent tube gradually, use the problem overcoming fluorescent tube and cause.
So, LED designs is become fluorescent tube shape, and directly substitute existing fluorescent tube, though fluorescent tube can be changed immediately be used as illumination use, but the LED lamp of lamp tube type designs because of the optical characteristics not for light emitting diode, make the distribution curve flux of overall light fixture not good, distribution curve flux schematic diagram as shown in Figure 1, general light fixture presents light shape and is mostly bat-wing, that is at sensitive surface place, while meeting brightness of illumination requirement, shadow surface is wider, and increases gradually from the luminous flux to both sides immediately below fluorescent tube; Only, this kind of light shape, though irradiating angle is comparatively large, light flux distribution is uneven, and the luminous flux immediately below fluorescent tube is minimum, causes illumination to lower or not enough and fail effectively to play illumination usefulness.
