Technical Field

[0001] The invention relates to a reflector of a lighting fixture and the lighting fixture. Background Art

[0002] Reflectors are a commonly used type of reflector that can greatly improve the light utilization of lamps and greatly increase the efficiency of lamps.

[0003] At present, the light source and the reflector of the LED light source are generally fixed on the lamp body. The reflector is far away from the light source and has low reflective efficiency. Once the reflector is installed, the position is fixed and cannot be adjusted according to the actual lighting needs to change the range and direction of the lighting. In addition, the general reflector is large in size, uses more materials, is heavy, and has high cost, which is not conducive to the economic benefits of the production enterprise. In addition, there are many LED lamps whose light sources do not have reflectors, which will illuminate places where no light is needed, causing light energy consumption and energy waste. Especially for LED lamps with cylindrical light sources, how to avoid the above problems has become a technical problem that technical personnel in this field need to solve. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a reflector for a lighting fixture.

The reflector is installed on the light-transmitting cover, and the reflector includes a reflector with a light-blocking and reflective surface and mounting ears located on both sides and fixedly connected to the reflector, and a bayonet is formed between the mounting ears on both sides. When the reflector is installed on the light-transmitting cover, the mounting ears are tightly embraced on the outer surface of the light-transmitting cover, and the reflector is enclosed on one side of the light-transmitting cover in the circumferential direction; and the size of the blocking range of the light transmitted from the light-transmitting cover by the reflector can be adjusted.

[0007] Preferably, the mounting ears are elastically deformable.

[0008] Preferably, the reflector includes a first reflector and a second reflector, the second reflector is slidably arranged on the outer surface of the first reflector, the mounting ear is fixedly connected to the first reflector, and the second reflector can slide toward the first reflector and overlap with it, and can also slide away from the first reflector and unfold relative to it.

[0009] Preferably, the first reflective plate and the second reflective plate are both in an arc shape.

[0010] Preferably, the mounting ear is integrally formed with the first reflector.

[0011] Preferably, the reflector further comprises an adjusting mechanism for adjusting the shielding range of the reflective surface of the reflector.

[0012] Preferably, the reflector is composed of an arc-shaped elastic reflective component, and the adjustment mechanism is used to drive the reflector to change elastically so that the arc radius of the reflector becomes larger or smaller.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Combination Figures 1 to 6 As shown, a reflector of a lighting fixture is provided. The light-transmitting cover 100 of the lighting fixture is cylindrical. The reflector is used to block and reflect the light transmitted from the cylindrical light-transmitting cover 100. The reflector is installed on the light-transmitting cover 100. The reflector includes a reflector with a light-blocking and reflective surface and mounting ears 10 located on both sides and fixedly connected to the reflector (the mounting ears 10 can be elastically deformed). The thickness of the reflector and the mounting ears 10 is 0.1mm-0.5mm. A bayonet is formed between the mounting ears 10 on both sides. When the reflector is installed on the light-transmitting cover 100, the light-transmitting cover 100 is inserted into the space formed by the mounting ears 10 and the reflector from the bayonet. The mounting ears 10 are tightly attached to the outer surface of the light-transmitting cover 100. The reflector is enclosed on one side of the circumferential direction of the light-transmitting cover 100. The size of the blocking range of the light transmitted from the light-transmitting cover 100 by the reflector can be adjusted.

[0027] In this example, the reflector is composed of one of an elastic mirror aluminum plate, a highly reflective plastic plate, a reflective glass plate, and a mirror stainless steel plate.

[0028] The mounting ears 10 extend in an arc shape. When the reflector is installed on the light-transmitting cover 100, the inner surface of the mounting ears 10 fits the outer surface of the light-transmitting cover 100. When the reflector is installed, the light-transmitting cover 100 of the lamp will be inserted into the space formed by the mounting ears 10 and the reflector from the bayonet, so that the mounting ears 10 hold the light-transmitting cover 100 tightly. There are two groups of mounting ears 10 on both sides, and they are respectively located at the two ends of the length direction of the reflector. After installation, the reflector is more stably connected to the light-transmitting cover 100.

[0029] In this example, the reflector is rotatably arranged on the light-transmitting cover 100. The reflector structure design in this example adopts a hugging method to dock with the light-transmitting cover 100. This structural design also enables the reflector to rotate freely, so that when the lamp is installed and powered on, the user can adjust the irradiation direction of the lamp as needed, saving light energy while meeting the use requirements of sufficient illumination, which is very practical.

[0030] In addition, the reflector also includes a guide handle 101 arranged on one end of the mounting ear 10. The guide handle 101 facilitates the light-transmitting cover 100 to be inserted into the space formed by the mounting ear 10 and the reflector from the bayonet, and also facilitates the reflector to be removed by hand after being grasped and pinched.

[0031] Further, regarding the adjustment of the size of the shielding range of the light transmitted from the light-transmitting cover 100 (the adjustment of the size of the shielding range is the adjustment of the illumination range of the lamp. The larger the shielding range, the smaller the illumination range, and the smaller the shielding range, the larger the illumination range), the present invention provides two different structural designs to achieve the adjustment of the size of the shielding range, as follows:

[0032] The first structural design method: Figures 1 to 3 As shown, the reflector includes a first reflector t1 and a second reflector t2, both of which are arc-shaped, and the second reflector t2 is slidably arranged on the outer surface of the first reflector t1, and the mounting ear 10 is fixedly connected to the first reflector t1, and the second reflector t2 can slide toward the first reflector t1 and overlap with it, and can also slide away from the first reflector t1 and unfold relative to it. Two guide ears t10 are arranged on the back side of the first reflector t1, and the second reflector t2 slides in the groove of the guide ear t10. In addition, bending blocking parts t20 are integrally formed on both sides of the second reflector t2, and the bending blocking parts t20 can ensure that the second reflector t2 will not fall off from the groove of the guide ear t10. When adjusting the size of the shielding range of the reflector, the second reflector t2 can be manually slid to achieve the adjustment. When the second reflector t2 slides and is relatively unfolded with the first reflector t1, the shielding range gradually increases, and the illumination range of the lamp gradually decreases. When the second reflector t2 slides and slowly approaches and overlaps with the first reflector t1, the shielding range gradually decreases, and the illumination range of the lamp gradually increases.

[0033] In this embodiment, the mounting ear 10 and the first reflector t1 are integrally formed, the reflector has a simple structure, and the production of the reflector is relatively simple and has a low production cost.

[0034] The second structural design method: Figures 4 to 6As shown, the reflector also includes an adjustment mechanism for adjusting the shielding range of the light-shielding reflective surface of the reflector t0. The reflector t0 is composed of an arc-shaped elastic reflective component, and the adjustment mechanism is used to drive the reflector t0 to change elastically so that the arc radius of the reflector t0 becomes larger or smaller. Specifically, the adjustment mechanism includes a first connecting plate b1 and a second connecting plate b2 (the first connecting plate b1 and the second connecting plate b2 are both L-shaped) respectively connected to the two sides of the reflector t0, an adjustment block x2 fixedly connected to the first connecting plate b1 and the second connecting plate b2, and an adjustment bolt x1 threadedly connected to the adjustment block x2, and the front end of the adjustment bolt x1 contacts the outer surface of the reflector t0.

[0035] When adjusting the size of the shading range of the reflector t0, the adjustment bolt x1 can be manually turned to drive the adjustment block x2 to move forward and backward, so that the first connecting plate b1 and the second connecting plate b2 drive the reflector t0 to deform. For example, when the adjustment bolt x1 is turned to make the adjustment block x2 move toward the side away from the reflector t0, the first connecting plate b1 and the second connecting plate b2 drive the reflector t0 to deform, so that the arc radius of the reflector t0 becomes larger and the arc depth becomes shallower. At this time, the shading range of the reflector t0 will become smaller, and the illumination range of the lamp will also become larger. For another example, when the adjustment bolt x1 is turned to make the adjustment block x2 move toward the side close to the reflector t0, the first connecting plate b1 and the second connecting plate b2 release the tension on the reflector t0, so that the reflector t0 is deformed, the arc radius becomes smaller, and the arc depth becomes deeper. At this time, the shading range of the reflector t0 will become larger, and the illumination range of the lamp will also become smaller.

[0036] In this embodiment, the mounting ear 10, the reflector t0, the first connecting plate b1 and the second connecting plate b2 are integrally formed. The production of the reflector is also relatively simple and has a low production cost.

[0037] In addition, the present invention also relates to a lighting fixture, which comprises the reflector described in the present invention.

[0038] In summary, the reflector of the lighting fixture of the present invention has a simple and practical structure, is very easy to install and disassemble, and adopts an economical structural design to save the use of materials to the maximum extent. In addition, through the use of the reflector, the user can adjust the illumination range of the lighting fixture with a cylindrical light-transmitting cover of the present invention according to actual use needs, thereby avoiding waste of light energy, improving the efficiency of light source use, and saving electric energy. In addition, the reflector of the present invention can also adjust the size of the shielding range of the reflector to the light transmitted from the light-transmitting cover according to the actual needs of the user for the illumination range. The larger the shielding range, the smaller the illumination range, and the smaller the shielding range, the larger the illumination range.

[0039] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
