Description

Light fixture

Technical field

The relevant a kind of light fixture improvement of the utility model, espespecially a kind of have a better distribution curve flux, can make the bright dipping of fluorescent tube produce that light is concentrated and the light fixture that improves brightness.

Background technology

Present decoration designs particularly office's decoration design, at interior space top, light steel frame ceiling is set in order to pursue simple common meeting attractive in appearance, and because having the design that is easy to dismantle, pipeline system keeps in repair and can facilitate within doors, therefore has been widely used in various buildings; Generally speaking, light steel frame ceiling is formed with several crisscross T-shaped bars, and be arranged with the framework of several square or rectangulars, comprise a pedestal in framework, and a plurality of fluorescent tubes that are installed on this pedestal, and be equipped with in framework a plurality of vertically with laterally staggered reflecting plate and flase floors, and the two ends of each reflecting plate and flase floor are positioned respectively framework, make fluorescent tube to avoid dropping by flase floor.

During use, the mercury in fluorescent tube forms thin mercury vapour through the evaporation of lamp tube ends filament heating, and mercury atom discharges ultraviolet light by the process of gas discharge, and ultraviolet ray excites the fluorescent material that is coated on tube wall again, and then sends white light; So, the mercury in fluorescent tube is contaminative is arranged and to the heavy metal element of harm, not only make fluorescent tube be not easy recycling, and easily cause the pollution of environment; Moreover, carbon reduction has become the emphasis of global evolution 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, people all conduct vigorous propaganda in relevant government bodies will form the custom that Turn Off Lights When Leaving; In recent years, fast development due to light emitting diode, and it has, and power consumption is low, assembly life-span is long, reaction speed is fast, power saving, the low pollution and the advantage such as volume is little, therefore, lifting along with technology, develop gradually and can replace the light-emitting diode lamp tube that fluorescent tube is used, use and overcome the problem that fluorescent tube causes.

So, LED designs is become the fluorescent tube shape, and directly substitute existing fluorescent tube, be used as the illumination use though can change immediately fluorescent tube, but the LED lamp of lamp tube type is not because of for the design of the optical characteristics of light emitting diode, make the distribution curve flux of whole light fixture not good, distribution curve flux schematic diagram as shown in Figure 1, general light fixture presents light shape and mostly is greatly bat-wing, that is to say at the sensitive surface place, when meeting the brightness of illumination requirement, shadow surface is wider, and increases gradually from the luminous flux to both sides under fluorescent tube; Only, this kind light shape, though irradiating angle is larger, light flux distribution is uneven, the luminous flux under fluorescent tube is minimum, causes illumination to lower or not enough and fail effectively performance illumination usefulness.
