Abstract
The utility model discloses a lighting device, it includes: two concave cambered surfaces are arranged oppositely, and the edges of the two concave cambered surfaces limit a light emission window on one side; a fluorescent lamp tube can be accommodated between the two reflecting sheets far away from the light emission window; between two reflection of light pieces, span in a plurality of light scattering grid washer of reflection of light piece and light emission window, a plurality of light scattering grid washer has a common grid washer support frame, grid washer support frame and a plurality of light scattering grid washer are buckled by same sheetmetal through the punching press and are formed, grid washer support frame is in light emission window department and the marginal fixed connection of two reflection of light pieces, the utility model discloses need not to install light scattering grid washer one by one, but material saving and improve the assembly efficiency of lamps and lanterns.
Description
Technical field
The utility model relates to the electric light source technology field, especially a kind of lighting device.
Background technology
The lighting device that common people are familiar with comprises: the reflecting piece that the planar mutual opposite of two concave arcs is provided with, and their edge is at the fixed light emitting window of a lateral confinement; Can hold a fluorescent tube between two reflecting piece away from light emitting window; Between two reflecting piece, be across several light scattering grid washers of reflecting piece and light reflection window; Usually each light scattering grid washer is inlaid in respectively in the corresponding groove of two reflecting piece, it is fixed, such innovation and creation have been done clearly to describe in the selected works of Chinese patent publication number CN1302363A and CN2086362U, the deficiency of this invention is: since need when factory or lamp installation with monolithic light scattering grid washer respectively setting-in in the corresponding groove of two reflecting piece, not only many consume materials but also be unfavorable for the raising of efficiency of assembling.
Summary of the invention
At above-mentioned deficiency, the utility model is intended providing a kind of lighting device, this lighting device to need not to install one by one light scattering grid washer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lighting device, and it comprises: the reflecting piece that the planar mutual opposite of two concave arcs is provided with, and their edge is at the fixed light emitting window of a lateral confinement; Can hold a fluorescent tube between two reflecting piece away from light emitting window; Between two reflecting piece, be across several light scattering grid washers of reflecting piece and light emitting window, the diffusing grid washer of several light has a common grid washer stand frame, described grid washer stand frame and several light scattering grid washers are to form by bending through punching press with a slice sheet metal, and described grid washer stand frame is fixedlyed connected with the edge of two reflecting piece at the light emitting window place; In order to strengthen the fastness that is connected of each light scattering grid washer and grid washer stand frame, be connected with two projections in its junction, the position of two projections is located at the same side of light scattering grid washer; Described projection can be to be roughly the right angle trigonometry shape, also can be to be roughly the right angle fan shape, or square, so just need not monolithic light scattering grid washer is installed.
Because grid washer stand frame of the present utility model and several light scattering grid washers adopt with a slice sheet metal punching press bending and form, so not only do not need to install one by one again light scattering grid washer, but also can the economical with materials cost, thereby reduced the material cost of manufacture of lighting device, the operating efficiency when improving factory or installation.

Among the figure, 1, the planar reflecting piece of concave arc, 2, the edge on the reflecting piece, 3, light emitting window, 4, fluorescent tube, 5, light scattering grid washer, 6, grid washer stand frame, 7, projection, 8, the Lamp base framework.
The specific embodiment
In Fig. 1, Fig. 2, the reflecting piece 1 that the planar mutual opposite of two concave arcs is provided with, and their edge 2 is at the fixed light emitting window 3 of a lateral confinement, can hold a fluorescent tube 4 between two reflecting piece 1 away from light emitting window 3, between two reflecting piece 1, be across several light scattering grid washers 5 of reflecting piece 1 and light emitting window 3, described several light scattering grid washers 5 have a common grid washer stand frame 6, described grid washer stand frame 6 and several light scattering grid sheets 5 are to form by bending through punching press with a slice sheet metal, as shown in Figure 3, Figure 4; Described grid washer stand frame 6 is fixedlyed connected with the edge 2 of two reflecting piece 1 at light emitting window 3 places, as welding or riveted joint.In order to strengthen the fastness that is connected of each light scattering grid washer 5 and grid washer stand frame 6, the position that is connected with 7, two projections 7 of two projections in its junction is located at the same side of light scattering grid washer 5; Described projection 7 can be to be roughly right angle trigonometry shape 7-1 as shown in Figure 5, as Fig. 6, shown in Figure 7, also can be to be roughly right angle fan shape 7-2,7-3, as shown in Figure 8 or square 7-4.As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, described lighting device can be installed in the Lamp base framework 8.
Lighting device of the present utility model can be designed to for example be used to install the light fixture of a light source, also can be used for installing on the light fixture of two and two above light sources, and they are the repetition of above-mentioned utility model.
