Description

Technical Field

[0001] The utility model belongs to the technical field of lamp optics, in particular to an anti-glare adjustable grille lampshade. Background Art

[0002] At present, in terms of lighting, long strip floodlights are widely used in many occasions and environments, becoming one of the important types of lamps for night scene lighting. With the increasing use of lighting lamps, light pollution has also become an important improvement link.

[0003] At present, the anti-glare of long strip floodlights is achieved by using an anti-glare shading plate on the outermost side or setting a honeycomb shading cover on the lamp body. Although it has a certain anti-glare effect, it has the following shortcomings: the external anti-glare shading plate can play a certain anti-glare role, but the anti-glare shading plate is relatively high, making the lamp appear too large, affecting the background beauty of the building; more importantly, when installed in a narrow embedded installation slot, the projection direction of the lamp cannot be adjusted, so that a large part of the light cannot be irradiated to the wall, causing waste, and the lighting effect of the lamp is greatly reduced. The use of honeycomb anti-glare lampshades is generally installed inside the lamp, with a compact structure and beautiful appearance, but the hexagonal honeycomb mesh affects the light effect too much, which requires increasing the power of the lamp and increasing the cost of use.

[0004] The above two anti-glare lampshades can play a certain anti-glare role, but the biggest drawback is that the irradiation direction of the shading cover cannot be adjusted, making it difficult for the lighting effect to achieve the designed effect. In view of the above reasons, the lighting market urgently needs a new type of grille lampshade that not only plays a good anti-glare role, but also can easily adjust the irradiation direction, making the installation of wall-washing lighting fixtures convenient and quick, and achieving the designed effect requirements.

[0036] A grille 03 is provided between the first fixing plates 02 at both ends, and the grille 03 is used to block and guide light, and has an anti-glare effect; the grille 03 is provided on the light-emitting surface of the floodlight 10, and the first baffle 01 is fixed on the floodlight 10;

[0037] It also includes a first adjustment plate 04; a first support hole 040 is formed on the first adjustment plate 04, and a first screw hole 041 is formed on one side of the first support hole 040;

[0038] A second supporting hole 020 is formed on the first fixing plate 02, and an arc-shaped first guiding groove 021 is formed on one side of the second supporting hole 020;

[0039] The top of both ends of the grille sheet 03 protrudes with a first positioning axis 030, and the bottom of both ends of the grille sheet 03 protrudes with a first rotation axis 031; the first positioning axis 030 and the first rotation axis 031 protrude from the grille sheet 03 in the shape of a long strip, preferably a cylindrical shape;

[0040] The first positioning axis 030 on the grille plate 03 is inserted into the second supporting hole 020 on the first fixing plate 02, and the first rotating axis 031 on the grille plate 03 is inserted into the first supporting hole 040 on the first adjusting plate 04. The first adjusting plate 04 and the first fixing plate 02 are rotated to the desired position, and the bolt passes through the first guide groove 021 and is screwed into the first screw hole 041 for fixing.

[0041] As described above, the specific adjustment and use process is as follows: the first positioning shafts 030 at both ends of the grille plate 03 are inserted into the second support holes 020 of the first fixing plate 02, and the first rotating shafts 031 at both ends of the grille plate 03 are inserted into the first support holes 040 of the first adjustment plate 04; the first adjustment plate 04 is attached to the first fixing plate 02, and the bolts pass through the first guide grooves 021 of the first fixing plate 02 and are screwed into the first screw holes 041 of the first adjustment plate 04 for fixing; the first baffles 01 at both ends are then fixedly connected to the two first fixing plates 02;

[0042] When adjustment is needed, loosen the bolts at both ends, move the first adjustment plate 04 to drive the grille 03 to rotate, and then the light output angle of the floodlight 10 can be changed. When the demand is met, tighten the bolts again; preferably, a flat washer can be added before the bolts are inserted into the first adjustment plate 04 to ensure that the bolts are fixed reliably;

[0043] This anti-glare adjustable grille lampshade can be matched with different types of long strip lamps, and the angle adjustment is convenient and quick, with strong adaptability and beautiful appearance. It can well show the advantages of LED lamps in environmental lighting, such as elegance, suitability, anti-glare, and energy saving, making many lighting effects more accurate, healthier, and lower in cost. It is suitable for use in most environments, and will be more and more popular, and will receive good social and economic benefits.

[0044] Furthermore, first fixing holes 010 are respectively formed at two ends of the first baffle plate 01 ; first fixing plates 022 protrude from two sides of the first fixing plate 02 ; and the first fixing plates 022 are inserted into the first fixing holes 010 and fixed.

[0045] As described above, the first baffle 01 and the first fixing plate 022 are connected to form a rectangular sleeve mounted on the corresponding floodlight 10;

[0046] Furthermore, the first fixing sheet 022 passes through the first fixing hole 010 and is bent 90 degrees to be locked and fixed.

[0047] As described above, when disassembly is required, the first fixing plate 022 can be straightened, and the first fixing plate 02 and the first baffle plate 01 adopt a bendable detachable connection structure.

[0048] Furthermore, a second fixing hole 011 is formed on the first baffle plate 01 and is attached to the side of the housing of the floodlight 10. A screw passes through the second fixing hole 011 and is screwed into the housing of the floodlight 10 to be fixed.

[0049] In another embodiment, after the adjustable angle grille lampshade is assembled, it is installed on the long strip floodlight 10, and screws are passed through the second fixing holes 011 on the left and right first baffles 01 to securely fix it.

[0050] Another first baffle 01 is disposed on the edge of the housing of the floodlight 10 , and a bottom edge of the other first baffle 01 protrudes from a bottom edge of the first baffle 01 .

[0051] As described above, the two first baffles 01 are high on one side and low on the other side, with one first baffle 01 at the bottom being close to the wall and the other first baffle 01 at the top being far from the wall, in order to block more light.

[0052] Furthermore, it also includes a first support plate 05; a third support hole 050 is opened on the first support plate 05, through which the grille plate 03 passes; and second fixing plates 051 protrude from both sides of the first support plate 05;

[0053] The two first baffles 01 are provided with third fixing holes 012; the second fixing sheet 051 is inserted into the third fixing hole 012 and bent 90 degrees to fix it. It can also be fixed by embedding, tight fitting or welding.

[0054] As described above, when the length of the grid sheet 03 is very long, in order to ensure that the grid sheet 03 does not bend and rotates synchronously, a first support plate 05 is disposed outside the grid sheet 03, and the first support plate 05 is connected between the two first baffles 01;

[0055] Furthermore, two first supporting holes 040 are formed on the first adjusting plate 04, and the first screw hole 041 is located between the two first supporting holes 040;

[0056] The first fixing plate 02 is provided with two second supporting holes 020 , and the first guiding groove 021 is located on one side of the two second supporting holes 020 ;

[0060] If there is one row of lamp beads, only two grille pieces 03 are enough. If there are two rows of lamp beads, three grille pieces 03 are needed. In this way, the irradiation direction can be rotated to adjust, and the grille piece 03 will not be placed on the lamp beads to affect the lighting effect.

[0061] By analogy, the number of the first support hole 040, the second support hole 020 and the third support hole 050 increases accordingly; the first baffle 01, the first fixing plate 02, the grille plate 03, the first adjustment plate 04 and the first support plate 05 can be made of structural materials such as steel plates and aluminum alloy plates.

[0062] Furthermore, the grid plate 03 is rotated at an angle of ±45°.

[0063] As mentioned above, it can meet the adjustment of different angles and is more practical; it can be made into different lengths.
