Description

Technical Field

[0001] The utility model relates to the field of lighting fixtures, in particular to a flat lamp structure adaptable to base plates of different widths. Background Art

[0002] In subway lighting and shopping mall lighting applications, flat panel lights are widely used as main lighting. In order to match the decoration, the width of flat panel lights varies. In the past, the sizes of flat panel lights were relatively small, generally 100mm, 150mm, 200mm, etc. Now, decoration companies are pursuing decoration styles and designing strange things, resulting in more and more non-standard widths of flat panel lights such as 86mm and 158mm. Although the total number of orders is considerable, the size of each width is very small, which makes it difficult to prepare materials, high cost, increased internal consumption, compressed corporate profits and extended delivery time. The market urgently needs new technical solutions to solve this problem.

[0003] At present, several common solutions on the market are to open profile molds of different widths according to the width required by customers and extrude the entire profile. This has the following disadvantages:

[0004] 1) Affected by the deformation of the extrusion die, the wider the lamp is, the thicker the profile wall is, and the weight ratio of the aluminum profile per unit width is getting heavier and heavier, which is costly!

[0005] 2) The minimum order quantity for aluminum profile extrusion is more than 300KG each time (because the mold needs to be replaced, which delays production time, and the extruded profiles in the machine adjustment process are all waste). When the order quantity is insufficient, only additional startup fees can be paid, resulting in huge waste;

[0006] 3) Every time a new width size appears, an aluminum profile extrusion mold must be opened. The mold fee is easily tens of thousands of yuan, and the mold opening time is 20-30 days. The mold fee and time investment are huge. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a flat lamp structure adaptable to base plates of different widths.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a flat lamp structure adapted to base plates of different widths, including:

[0009] Base plate; an LED light source is fixed on the base plate;

[0010] A pair of frames, wherein the bottoms of the two frames are respectively provided with first slots, and the first slots are used to accommodate the side edges of the bottom plate in the width direction;

[0011] A pair of end covers; the bottoms of the two end covers are respectively provided with second slots, and the second slots are used to accommodate the side edges of the bottom plate in the length direction.

[0012] The beneficial effect of the utility model is that the utility model achieves the material versatility of flat panel lights of different widths by standardizing the design of the frame. When the width of the lamp changes, it has no effect on the frame, because the frame and the base plate are fixed by a slot and are not integrated. Through the slot design, the base plate can be well fixed to the frame without screwing, so as to save labor time and improve the appearance and flatness. The change in the width of the lamp also affects the LED light source module and the end cover. The LED light source module only needs the aluminum base plate supplier to adjust the cutting size of the cutter when ordering the aluminum base plate, and no separate material preparation is required. The aluminum alloy profile end cover can also be cut according to the required width of the project, and no separate material preparation is required. Therefore, the change in the width of the lamp will not affect the frame, LED light source and end cover, and will not require additional material preparation, resulting in startup fees or long delivery time, thereby achieving the purpose of universality and standardization.

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figure 1-6 The utility model provides a flat panel lamp structure adapted to base plates of different widths, including:

[0024] A bottom plate 1; an LED light source is fixed on the bottom plate 1;

[0025] A pair of frames 2, wherein the bottoms of the two frames 2 are respectively provided with first slots 21, and the first slots 21 are used to accommodate the side edges of the bottom plate 1 in the width direction;

[0026] A pair of end covers 3; the bottoms of the two end covers 3 are respectively provided with second slots 31, and the second slots 31 are used to accommodate the side edges of the bottom plate 1 in the length direction.

[0027] From the above description, it can be seen that in the above-mentioned flat panel lamp structure that adapts to base plates of different widths, the material versatility of flat panel lamps of different widths is achieved by standardizing the frame design. After the width of the lamp changes, it has no effect on the frame, because the frame and the base plate 1 are fixed by a slot and are not integrated. Through the slot design, the base plate can be well fixed to the frame without screwing, which saves labor time and improves the appearance and smoothness. The change in the width of the lamp also affects the LED light source module and end caps. The LED light source module only needs the aluminum base plate supplier to adjust the cutting size of the cutter when ordering the aluminum base plate, and does not need to be prepared separately. The aluminum alloy profile end caps can also be cut according to the required width of the project, and do not need to be prepared separately.

[0028] Furthermore, the flat panel lamp structure adapted to base plates of different widths further includes a transparent tempered glass mask 4 and a PC diffuser 5;

[0029] The tops of the two frames 2 are respectively provided with third card slots 22, and the third card slots 22 are used to accommodate the side edges of the bright tempered glass mask and the PC diffuser plate 5 in the width direction;

[0030] A fourth slot 32 is respectively provided on the top of the two end covers 3 , and the fourth slot 32 is used to accommodate the side edge of the bottom plate 1 in the length direction.

[0031] From the above description, we can know that in order to meet the fire protection requirements of Class A flame retardant grade, the lamp housing is made of non-combustible materials, the light-transmitting mask is transparent tempered glass, and the inner lining is PC diffusion plate to prevent glare; it is also fixed by the slots on the frame and end cover to achieve the material versatility of flat panel lights of different widths.

[0032] Furthermore, in the above-mentioned flat panel lamp structure adaptable to base plates of different widths, the base plate 1 is a silk-screened aluminum base plate provided with an LED light source.

[0033] From the above description, we can know that in order to save costs and man-hours, the traditional aluminum base plate + aluminum base plate combination is replaced by a screen-printed aluminum base plate as the base plate. Usually, the base plate and aluminum base plate of the flat panel light are two parts. The aluminum base plate is called an LED light source after the LED lamp beads are attached. The conventional practice is to fix one or more LED light sources to the base plate of the lamp by bonding with thermal conductive silicone or screws and buckles.

[0034] The utility model uses the screen-printed aluminum substrate as the bottom plate, which has the following advantages: 1) one or more LED-specific aluminum substrates can be omitted, saving material costs; 2) the labor hours for fixing the aluminum substrate to the bottom plate of the lamp are eliminated; 3) the parallel connection of multiple aluminum substrates can be eliminated, saving wire material costs and welding labor hours; 4) the cost of the screen-printed aluminum substrate is much cheaper than that of the conventional film-exposed aluminum substrate; 5) the aluminum substrate has a variety of thicknesses, for example, the conventional thicknesses are 1.0mm, 1.2mm, 1.5mm, 2.0mm, etc. When the width of the lamp is too large, the strength of the aluminum substrate can be increased by using aluminum substrates of different thicknesses, which is very convenient and does not require specially customized materials.

[0035] Furthermore, in the above-mentioned flat lamp structure adaptable to base plates of different widths, the frame 2 is a right-angled triangle structure, including right-angled sides in the horizontal and vertical directions, and a hypotenuse facing the direction of the LED light source.

[0036] It can be seen from the above description that the frame structure of the right-angled triangle is more stable.

[0037] Furthermore, in the above-mentioned flat panel lamp structure adaptable to base plates of different widths, a white polyester powder layer is provided on the surface where the bevel is located.

[0038] From the above description, we can see that the beveled edge of the right-angled triangle aluminum profile frame has a strong reflective effect after being sprayed with white polyester powder, which can significantly improve the lighting efficiency of the lamp. According to our company's comparison, compared with the straight-edged lamp frame, the frame with reflective beveled edge can improve the lighting efficiency of the lamp by more than 30%.

[0039] Furthermore, in the above-mentioned flat panel lamp structure adaptable to base plates of different widths, the height of the lower side wall of the first slot is greater than the height of the upper side wall.

[0040] From the above description, it can be seen that the height of the lower side wall of the first slot is greater than that of the upper side wall. The lower side wall of the first slot is more conducive to supporting the bottom plate, so that the bottom plate 1 is more stably connected to the slot.

[0041] Furthermore, in the above-mentioned flat lamp structure adapting to base plates of different widths, the edges of the upper side wall and the lower side wall of the first clamping groove 21 are respectively provided with clamping protrusions facing the base plate 1 .

[0042] It can be seen from the above description that the provision of the clamping protrusion makes the clamping of the bottom plate 1 on the clamping slot more stable.

[0043] Furthermore, in the above-mentioned flat lamp structure adapting to base plates of different widths, an EVA foam layer 6 is provided on the side of the end cover 3 facing the frame.

[0044] From the above description, it can be seen that EVA foam provides gap filling for the end cap and other components of the lamp body to prevent dust and insects from entering the interior of the lamp.

[0045] Furthermore, the flat panel lamp structure adapted to base plates of different widths further includes a hanging bracket 7, and both ends of the hanging bracket 7 are detachably connected to the bottom ends of the corresponding frame.

[0046] Furthermore, the flat panel lamp structure adapted to base plates of different widths further includes a driver 6 fixed to the bottom surface of the base plate 1 .

[0047] Embodiment 1

[0048] See also Figure 1-Figure 6 This embodiment discloses a flat panel lamp structure adapted to base plates of different widths, including:

[0049] Base plate 1; an LED light source is fixed on the base plate 1; the base plate 1 is a silk-screen aluminum substrate provided with an LED light source.

[0050] A pair of frames 2, the bottoms of the two frames 2 are respectively provided with first card slots 21, the first card slots 21 are used to accommodate the side edges in the width direction of the bottom plate 1; the frame 2 is a right-angled triangle aluminum profile structure, including right-angled sides in the horizontal and vertical directions, and a hypotenuse facing the direction of the LED light source. The surface where the hypotenuse is located is provided with a white polyester powder layer. The height of the lower side wall of the first card slot 21 is greater than the height of the upper side wall. The edges of the upper side wall and the lower side wall of the first card slot 21 are respectively provided with card-connecting protrusions facing the bottom plate 1.

[0051] A pair of end covers 3; the bottoms of the two end covers 3 are respectively provided with second slots 31, and the second slots 31 are used to accommodate the side edges of the bottom plate 1 in the length direction. The end covers 3 are provided with an EVA foam layer 6 on the side facing the frame 2.

[0052] It also includes a transparent tempered glass mask 4 and a PC diffuser 5; the tops of the two frames 2 are respectively provided with third card slots 22, and the third card slots 22 are used to accommodate the side edges in the width direction of the transparent tempered glass mask and the PC diffuser 5; the tops of the two end covers 3 are respectively provided with fourth card slots 32, and the fourth card slots 32 are used to accommodate the side edges in the length direction of the base plate 1.

[0053] The device further comprises a hanging bracket 7, the two ends of which are detachably connected to the bottom ends of the corresponding frames 2. The device further comprises a driver 6 fixed to the bottom surface of the bottom plate 1.

[0054] In summary, the utility model achieves the material versatility of flat panel lamps of different widths by standardizing the design of the aluminum frame. After the width of the lamp changes, it has no effect on the triangular aluminum profile frame, because the triangular aluminum profile frame and the LED light source module that also serves as the bottom plate of the lamp are fixed by a slot and are not integrated.

[0055] The change in the width of the lamp mainly affects the LED light source module and the aluminum alloy profile end cap. For the LED light source module, the aluminum substrate supplier only needs to adjust the cutting size when ordering the aluminum substrate, and no separate material preparation is required. Since the screen-printed aluminum substrate is used, there is no need to make a separate film. The aluminum alloy profile end cap is an extruded profile with a standard length of 6 meters. It can be cut according to the width required by the project and does not need to be prepared separately.

[0056] Therefore, the change in the width of the lamp will not affect the triangular aluminum profile frame, and the LED light source module (3) and the aluminum alloy profile end cover will not require additional material preparation, resulting in startup costs or long delivery time, thereby achieving the purpose of universality and standardization.

[0057] The utility model is adapted to the flat panel lamp structure of different widths of base plates, and further reduces material costs, improves product competitiveness, and enhances corporate profitability by optimizing structural design. Through the versatility of materials, it reduces inventory pressure and improves delivery cycle, providing customers with high-quality services; increasing brand added value and creating a good brand reputation.
