Abstract

The utility model relates to a grid-light disk, which comprises a lamp bracket having a bottom plate, a reflection grid, a gridding strip and a lamp assembly, and is characterized in that the lower end of the reflection grid is bent outwards from the reflection grid for forming a first hem; a second hem is arranged at the bottom plate corresponding to the first hem; the first hem and the second hem are of line contact; the reflection grid has the same arc with the butt joint of the bottom plate; the bottom plate has a flat surface at the bottom and arc surfaces at the two sides which have the same arc with the reflection grid; an axial bulge of V-shape is arranged at the center of the flat surface. The utility model may improve the utilization ratio of a light source effectively and saves energy sources.

Description

A kind of grid lamp disc

Technical field

The utility model relates to a kind of light fixture, particularly a kind of the grid lamp disc that fluorescent tube is used is installed.

Background technology

The grid light fixture is a kind of household that is widely used in, the light fixture of office space and public place, in today of energy growing tension, the quality of energy-saving effect is a businessman, producer and consumer's main consideration, except energy-conservation on the light emitting source, the energy-saving effect of light fixture also can not be ignored, the lamp panel structure of existing Grille lamp as shown in Figure 1, this lamp panel mainly comprises the lamp bracket 1 with base plate 4, reflection grid 2, grizzly bar (not shown) and fluorescent tube assembly, wherein the fluorescent tube assembly comprises ballast 3 and the lamp tube socket (not shown) of reflection between the grid 2 that places reflection grid 2, it is straight tabular that the base plate 4 of existing lamp bracket 1 is, such lamp panel can not reflect away fluorescent tube vertical irradiation light partly effectively, utilization rate is low, moreover, base plate 4 is owing to be directly tabular, in order to reach certain bending resistance curvature, its material also has requirement that certain thickness is arranged, and also is difficult for accomplishing on material saving; And the base plate of using as reflecting surface 4 and reflection grid 2 require its surface that cut can not be arranged, otherwise will influence reflecting effect, so

reflection grid

2 and 4 of base plates remain with bigger distance D, as shown in Figure 2, distance D generally is 4-5mm, such design causes a result, and the reflecting surface effective area as reflection grid 2 and base plate 4 formation reduces exactly.

Summary of the invention

The utility model is intended to address the above problem, and provides a kind of more large program ground to dwindle reflection grid and backplane interface distance, and reverberation efficient is higher, also the abundant grid lamp disc of the light at the reflection source back side.

For reaching above purpose, the utility model provides this grid lamp disc, comprise lamp bracket, reflection grid, grizzly bar and fluorescent tube assembly with base plate, it is characterized in that, reflection grid lower end lateral buckling outside grid, and form first flanging, base plate is provided with second flanging corresponding to the described first flanging place, first flanging forms line with second flanging and contacts, and the reflection grid is consistent with the radian of base plate joint.

Described base plate bottom be the plane, and both sides are and reflect the corresponding to cambered surface of grid radian, and described plane central authorities are provided with axial projection.

Described projection is the V-arrangement projection.

Use the lamp panel of the utility model structure, can improve the availability of echo area, and the light at the light source back side can be reflected, utilized light source more large program; Projection on the base plate plays the effect of reinforcement, improves the rigidity of base plate, changes an angle and says, and under the prerequisite of the original rigidity of assurance, thickness that can the attenuate base plate promptly saves material.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 3, Figure 4, this grid lamp disc that the utility model provides comprises that 10 of lamp bracket 10, lamp brackets with base plate 11 are laid with the reflection grid 20 of reflective concave mirror shape equably, are provided with grizzly bar 30 with reflection grid 20 vertical racks, fluorescent tube assembly 40 comprises ballast 41 and lamp tube socket (not shown), with reference to Fig. 5, the 21 outwards bendings of reflection grid lower end, and forming first flanging 22, base plate 11 is provided with second flanging 12 corresponding to first flanging, 22 places; Second flanging 12 is divided into adjacent reflecting surface 111 and non-echo area 112 to base plate 11, at first flanging 22 and second flanging, 12 joints, echo area 111 is consistent with the radian of reflection grid 20, the whole structure that helps the light reflection strengthens, non-echo area 112 forms a cavity 50 with the back side of reflection grid 20, and ballast 41 is arranged in this cavity 50; In order effectively to increase reflecting surface, require the distance of 12 of first flanging 22 and second flangings the smaller the better, so in the utility model, adopt line contact design, when promptly installing, first flanging 22 and second flanging 12 are close as far as possible, even contact also is these two soft and smooth flanging contacts, contact-making surface forms line contact, area minimum, be not easy scuffing, scratch reflecting surface, in the present embodiment, this can be less than 1mm apart from minimum, and the distance of comparing existing lamp panel is 4-5mm, distance reduces, and reflective surface area obviously increases many; Simultaneously, the light that send at the back side of light source in existing lamp panel fails to be reflected away fully, in the present embodiment, the bottom of echo area 111 is planes, referring to Fig. 6, and is axially arranged with projection 60 in the middle of this bottom, projection 60 is V-shaped, promptly be made of two crossing inclined-planes 61, like this, the light that the light source back side is sent can reflect by inclined-plane 61, certainly cambered surface also can be arranged in the bottom of echo area 111, but can correspondingly increase the thickness of this lamp panel, increase takes up space, and making material also can correspondingly increase, in the utility model, the projection 60 that base plate is provided with plays the effect of reinforcement undoubtedly, and rigidity is increased, so, under the prerequisite that guarantees original rigidity, can the attenuate base plate thickness, reduce rolled steel dosage, also can save cost.
