Technical field
The utility model relates to a kind of light fixture.
Background technology
Electric light is used quite extensive in daily life, the quality of electric light has direct influence to people's production and life.Current straight type lamp is used for people in daily working and learning more, wherein straight type lamp adopts fluorescent lamp (being low pressure mercury lamp) more, it is to utilize the radiation ultraviolet ray in discharge process of hypobaric mercury vapour, thereby it is luminous to make fluorescent material send the principle of visible light, so it belongs to low pressure arc discharge light source.Two filaments are housed in the fluorescent lamp.Scribble electronic emission material triplex carbonate (brium carbonate, strontium carbonate and calcium carbonate) on the filament, be commonly called as the electronics powder.Under the alternating voltage effect, filament is alternately as negative electrode and anode.Tube inner wall scribbles fluorescent material.Be filled with argon gas and a spot of mercury of 400Pa-500Pa pressure in the pipe.After the energising, liquid mercury flashes to the mercury vapour that pressure is 0.8Pa.Under electric field action, mercury atom constantly is provoked into excitation state from reset condition, and spontaneous transition is to ground state then, and (main peak value wavelength is 253.7nm, accounts for the 70-80% of whole radiant energy to give off the ultraviolet ray of wavelength 253.7nm and 185nm; The minor peaks wavelength is 185nm, account for whole radiant energy 10%), to discharge unnecessary energy.Fluorescent material sends visible light after absorbing ultraviolet emittance.Fluorescent material difference, the light that sends are also different, the cause of Here it is fluorescent lamp can make white and various colours.Because the electric energy major part that fluorescent lamp consumed is used for producing ultraviolet ray, therefore, the luminous efficiency of fluorescent lamp is present comparatively energy-conservation electric light source usually than incandescent lamp and halogen tungsten lamp height.
But because the lamp interior of existing straight type fluorescent lamp does not have reflex reflector or reflex reflector unreasonable, the light that causes lamp both sides and back to be sent has been wasted, and has reduced the light utilization that lamp sent, and has caused the waste of resource.
Therefore the current problem that needs to solve is that the lamp interior that solves current straight type lamp does not have reflex reflector or reflex reflector unreasonable, the lower problem of light source utilization rate that causes lamp to send.
The utility model content
Technical problem to be solved in the utility model provides a kind of light fixture, and the lamp interior that has solved current straight type lamp does not have reflex reflector or reflex reflector unreasonable, causes the lower problem of light source utilization rate of lamp, has improved the light source utilization rate of lamp.
In order to address the above problem, the utility model provides a kind of light fixture, comprises straight type lamp and lampshade, and described lampshade inner surface has a left vertical echo area, a top refracting sphere and the vertical reflection district, a right side along described straight type lamp longitudinal extension; Wherein, described top refracting sphere and is positioned at described straight type lamp top between described left vertical echo area and right side vertical reflection district; The cross section of described top refracting sphere is the obtuse angle shape that an opening makes progress; Along level direction from left to right, the cross section of described left vertical echo area is a monotonic increase convex curve arc; The cross section in vertical reflection district, described right side is a monotone decreasing convex curve arc.
Compared with prior art, use light fixture of the present utility model, under the prerequisite that does not increase energy consumption, solved the waste problem of the light that sends in lamp both sides and back effectively, improved the light utilization that lamp sent largely, increase the illuminance of light area by a relatively large margin, saved resource.
Description of drawings
Fig. 1 is the application schematic diagram of light fixture of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
In the utility model, because the popularity of fluorescent lamp applications, straight light tube can use straight type fluorescent tube to describe as an example, and other straight light tubes also can be used method of the present utility model certainly, and the utility model is not done any qualification to this.
The light that is sent in view of straight type fluorescent tube is evenly to distribute with 360 ° of circumference, main design of the present utility model is: as shown in Figure 1, a kind of light fixture, comprise straight type lamp and lampshade, described lampshade inner surface has a left vertical echo area, a top refracting sphere and the vertical reflection district, a right side along described straight type lamp longitudinal extension; Wherein, described top refracting sphere and is positioned at described straight type lamp top between described left vertical echo area and right side vertical reflection district; The cross section of described top refracting sphere is the obtuse angle shape that an opening makes progress; Along level direction from left to right, the cross section of described left vertical echo area is a monotonic increase convex curve arc; The cross section in vertical reflection district, described right side is a monotone decreasing convex curve arc.
Use light fixture of the present utility model, under the prerequisite that does not increase energy consumption, solved the waste problem of the light that sends in lamp both sides and back effectively, improved the light utilization that lamp sent largely, increase the illuminance of light area by a relatively large margin, saved resource.
Described lampshade inner surface further has along a left side refracting sphere of described straight type lamp longitudinal extension and a right side refracting sphere; Wherein, described left side refracting sphere is positioned at the left side of described left vertical echo area, and described right side refracting sphere is positioned at the right side in vertical reflection district, described right side; Along level direction from left to right, the cross section of described left side refracting sphere is a monotonic increase sag vertical curve arc; The cross section of described right side refracting sphere is a monotone decreasing concave curved surface arc.
The cross section in described left vertical echo area and right side vertical reflection district is that conic is linear.Wherein, as long as described left vertical echo area and the shape of the cross section in right side vertical reflection district can make reflection ray that straight type fluorescent tube emits beam basic vertical with angle between the sensitive surface, the utility model is not done any qualification to this.
The cross section in described left vertical echo area and right side vertical reflection district be shaped as the shape that can make the vertical substantially directive sensitive surface of most of reverberation.
The cross section in described left vertical echo area and right side vertical reflection district is parabola shaped.Wherein, as long as described left vertical echo area and the shape of the cross section in right side vertical reflection district can make reflection ray that straight type fluorescent tube emits beam basic vertical with angle between the sensitive surface, for example can be a hyp part, the utility model not be done any qualification to this.
The cross section of described left side refracting sphere and right side refracting sphere is that conic is linear.The cross section of described left side refracting sphere and right side refracting sphere is parabola shaped.Being shaped as of the cross section of described left side refracting sphere and right side refracting sphere can make most of reverberation shape of ejaculation outside the left-external side and the right side respectively.
