The specific embodiment
With reference to the accompanying drawings the utility model is described further.
Main thought of the present utility model is to wish to make single tubes can realize the wing distribution curve flux of bat by grill designs that therefore, light fixture grid of the present utility model is installed on the below of single tubes.The same with existing common grid, on grid, be formed with light shielding part and transmittance section equally, but different is, existing grid generally is plane, and grid of the present utility model, referring to Fig. 1, grid 100 of the present utility model, comprising bottom 10 in shape, left side 20 and right side 30, described left side 20 merges the upper left side extension of side left with the left side edge joint of described bottom 10, described right side 20 engages with the right edge of described bottom 10 and the upper right side extension of side to the right, and described bottom 10 is parallel with sensitive surface, and 10 positions corresponding with described fluorescent tube have the groove 101 that at least one makes progress along the opening of fluorescent tube direction longitudinal extension in the bottom.
In the embodiment shown in fig. 1, described left side 20 is a linear with the cross section of right side 30.According to embodiment of the present utility model, on described cross section, the angle of described left side and bottom roughly is 135 degree, and the angle of described right side and bottom roughly is 135 degree.In fact, concrete angle can according to the distance of fluorescent tube, the combined factors adjustment such as height of lampshade, be not limited to 135 degree.
And the cross section of left side and right side also can be broken line shape (for example opening is towards the uncovered trapezoidal or triangle of fluorescent tube direction); Also can be shaped form, bowl-type or arc etc. for example.
The shape of cross section of groove 101 also can be various, for example V-shaped or U-shaped.
The direct light that the fluorescent tube lower side is sent in left side 20 and right side 30 block and reflect after shine sensitive surface, make light softer equally.
Existing light fixture grid is plane mostly, and be chessboard grid type hollow out and form the transmittance section, lighttight part is a light shielding part, as long as being transformed into above-mentioned shape shown in Figure 1, the shape of this grid can realize the purpose of this utility model to a certain extent, if but further transform according to following optimal way, then can further strengthen effect.
For example, the light shielding part that grid forms is made by reflectorized material towards a side of fluorescent tube, light shielding part not only stops light like this, and can be strong with light to fluorescent tube top reflection, as shown in Figure 2, fluorescent tube top generally has a reflex reflector 200, this part light can be reflected once more to sensitive surface after receiving the light that grid 100 reflects, not only strengthen light efficiency, and reduced dazzle.
Shown in Fig. 2, in lampshade 300, has a reflex reflector 200 that is used with grid 100, the shape of this reflex reflector is not limited to shown in Figure 2, the shape of the reflex reflector in the existing light fixture can realize the purpose of this utility model to a certain extent, shown in Figure 2 only is a kind of optimal way, and this reflex reflector 200 is divided into a left side, a pars intermedia, a right side equally.The limit, left side of left side and pars intermedia joins merging to the extension of the lower left on the limit, left side of pars intermedia, the right edge of right side and pars intermedia is joined and is merged the lower right extension on limit to the right, the cross section of left side and right side is shape, broken line shape or arc linearly, preferably, the edge is direction from left to right, the left side cross section is monotonic increase convex curve shape, and the right side cross section is monotone decreasing convex curve shape.Described pars intermedia can be a del, preferred angle is greater than 135 degree, preferred, as shown in Figure 2, the shape of described pars intermedia also can be further divided into a top region, left side district, a right side region, top region is above-mentioned del, and the left side district links to each other with the limit, left side of top region and below extension left, and right side region links to each other with the right edge of top region and extends to the lower right; The cross section of described left side district and right side region can be linear, broken line shape or camber line shape, and preferred, left side district cross section is the monotonic increase concave curved, and the right side region cross section is the monotone decreasing concave curved.
The transmittance section that forms on the grid can be distributed on bottom and left side and the right side, preferably, be that the transmittance section only is distributed on the described bottom 10, and left side 20 is all light shielding part with right side 30, like this, the reflective area of light shielding part is bigger, and the direct light that blocks the fluorescent tube lower side that can be tighter.And when described transmittance section is uniformly distributed in described groove 101 both sides, then can present the batswing tab shape by the balanced more distribution curve flux that makes.If the transmittance section also is set on left side and right side, the irradiation brightness of increase sensitive surface that then can be suitable also can be considered to implement in certain embodiments, and the utility model does not limit this.
To shown in Figure 8, described transmittance section is formed by hollow out or is made up of the various patterns that transparent or semitransparent material forms as Fig. 3.Can be the rectangle combination that vertically arrange apportion groove both sides, the oval combination, circular combination, diamond mixes combination of shapes, or decorates line (as Fig. 6 and shown in Figure 8) in the formation of indivedual transmittance sections, and the utility model does not limit this.Part outside the transmittance section that is formed by these combination patterns is exactly a light shielding part.
Design as non-integral, then be easy for installation, the side of described grid can have installation portion, after the installation, most of direct light that the limit, left side of described grid and the extended height of right edge send the lower side of described fluorescent tube is blocked, and most of direct light that upper side is sent can preferably be blocked by the left side of reflex reflector 200 and right side, like this, when coming back, the user almost cannot see fluorescent tube, most of light that fluorescent tube sends all is to shine to sensitive surface by the transmittance section of grid, not only realize the wing distribution curve flux of bat of single tubes, and further reduced dazzle, avoided high light dazzling.
