Description

FIELD OF TECHNOLOGY

[0001] The proposed utility model relates to the field of technology associated with lamps, in particular, to a lighting device.

BACKGROUND

[0002] A light emitting diode (LED) is a semiconductor that converts electricity to light. The principle of light emission of an LED differs from the principle of light emission by a tungsten filament of an incandescent lamp and the principle of light emission by a three-color color modifier of an energy-saving lamp. The LED uses the phenomenon of electroluminescence. The LED is widely used in the lighting industry due to its characteristics, which include a long service life, high light output, low radiation, low power consumption and the like.

[0003] A LED panel light is a commonly used type of LED light and is often used as a high quality indoor light. The LED panel light contains an aluminum frame, an optically transparent panel and an LED lighting panel. During installation, the LED lighting panel is attached to an aluminum frame. An optically transparent panel covers the aluminum frame and surrounds the LED lighting panel. Since the optically transparent panel of a conventional LED panel lamp has a relatively large area, the cost of production increases. Meanwhile, the panel light is also relatively limited in design and has a single design form, which may not satisfy the needs of the market.

[0003.1] Background of the invention.

[0003.2] Document RU 2561712 C2, F21S4 / 00, 09/10/2015, discloses a solution related to the field of lighting engineering and intended for illumination, mainly of internal premises, trading floors, corridors. The housing is symmetrical about the longitudinal plane. The circuit board of the light module is tightly pressed to the base of the heat-sink profile with screws to the central U-shaped groove, to which side covers are also pressed from opposite sides, with one screw each. Symmetrical slots for attaching a translucent screen are facing outward with respect to the closed contour of the profile. The side and back walls of the body are made corrugated. Effect: simple design, reduction of dimensions, which is achieved by the fact that a heat sink profile with a rear and two side walls is used as a lamp housing with the formation of a closed cavity, on the back wall of which a groove is made on the outside for mounting to an external structure.

[0003.3] The closest analogue.

[0003.4] The closest analogue to the proposed utility model is the solution disclosed in document RU 2561712 C2, F21S4 / 00, 09/10/2015. However, it was found that such a box-shaped LED lamp, as disclosed in the document RU 2561712 C2, has a small lighting area. At the same time, the light-emitting panel of a traditional LED panel lamp, as described above, has a relatively large area, which leads to an increase in cost.

[0003.5] Thus, the technical problem solved by the proposed utility model is to increase the coverage area of the LED bar-shaped luminaire, while providing maximum savings in the amount of material needed to make the light-emitting panel of the LED panel luminaire, compared to traditional non-hollow LED lamp.

[0024] FIG. 1 is a perspective view of a lighting device in accordance with an embodiment of the utility model. Figure 2 presents the cross section of the lighting device in accordance with the embodiment of the utility model. In accordance with figures 1 and 2, the proposed lighting device comprises a mounting part 1, an optically transparent diffuser 2 and one or more lighting panels 3. The front and rear parts of the mounting part 1 are connected to form a hollow mounting frame. In an illustrative embodiment, the mounting portion 1 has a substantially rectangular closed shape. The mounting part 1 has a mounting surface 11 having a protrusion 4 extending from the mounting surface 11. The protrusion 4 has a mounting recess 41 formed on the side of the protrusion 4 facing away from the mounting surface 11. A lighting panel 3 is attached to the bottom of the mounting recess 41. One or more light-emitting elements 5 are attached to the panel 3. The diffuser 2 has a hole latched in the groove of the recess 41 by means of a mounting unit to ensure that the panel 3 is placed in the recess 41. As a result of the implementation of the hollow mounting frame can be reduced by covering the area of the diffuser 2. Further, the mounting frame may be structurally resolved in various ways. The hole of the diffuser 2 is snapped into the groove of the recess 41 of the protrusion 4 by means of a mounting unit in order to simplify and facilitate the attachment of the diffuser 2.

[0025] The mounting frame may be of a circular, elliptical, square, rectangular or special shape. The mounting part 1 can be structurally solved in accordance with the shape required for the mounting frame. For example, if the frame is rectangular, then part 1 may be a rectangular structure formed by joining four frame rails. Reiki connected end to end to form a rectangular frame as a result. In another embodiment, the mounting frame is made in the form of an integral part by extrusion or injection molding.

[0026] In the illustrated embodiment, the mounting part 1 comprises four frame rails which are connected in series end-to-end to form a mounting frame with a hollow rectangular structure. The rails are made by extruding an aluminum alloy, so that the weight of the mounting frame is reduced, and the rate of heat dissipation from the mounting frame is increased.

[0027] When the mounting portion 1 includes four frame rails, the panels 3 and the diffuser 2 can be located on all rails to form a closed light-emitting structure. Panels 3 and diffusers 2 can also be located on all frame rails to form a closed light-emitting structure. The panels 3 and diffusers 2 can also be located at least on the frame rail for the formation of intermittent light-emitting structures. For example, two opposite rails are made with a panel 3 and with a diffuser 2 (optically transparent small diffuser) for the formation of two parallel rack-shaped light-emitting structures.

[0028] In particular, the diffuser 2 is made of plastic with high optical transparency. The diffuser 2 made of plastic can be flexible. During the design, the openings can be structurally solved with relatively small dimensions, so that the diffuser 2 is mounted on the protrusion 4 by clicking to prevent the diffuser 2 from separating from the protrusion 4. In another embodiment, the diffuser 2 is made of a thin aluminum plate. The diffuser 2 is made with windows located at locations where transparency is required. Windows are covered with optically transparent plates, which can be made of glass or transparent plastics.

[0029] Additionally, the panel 3 is a printed circuit board (PCB). The light emitting element 5 is a light emitting diode (LED). LED 5 is located on panel 3.

[0030] In a preferred embodiment of the proposed utility model, the angle of exit of the light beam from the light emitting element is at least 90 °. The angle of exit of the light beam from the LED 5 determines the light-emitting region of the entire lighting device. The light emitting region of the lighting device is relatively large when the angle of exit of the light beam from the light emitting element is at least 90 °.

[0031] Additionally, the protrusion 4 is designed to reduce the difficulties associated with fixing the diffuser 2 with the mounting part 1, and to increase the life of the lighting device. Accordingly, when considering reducing the difficulties associated with fixing the diffuser 2, a method of increasing the angle of exit of the light beam from the LED 5 becomes relatively important. In this embodiment, a method of reducing the depth of the mounting recess 41 can be used. More specifically, the mounting recess 41 provides mounting space for panels 3. If the mounting recess 41 becomes less deep, then its walls to a lesser extent cover the LED 5, while the angle of exit of the light beam from the LED 5 increases. In this embodiment, the angle of exit of the light beam from the LED 5 is 100 ° - 180 °.

[0032] In another preferred embodiment, the fastener assembly comprises first fastening means 6 and second fastening means 7 cooperating with each other. The first fastening means 6 are located in the groove of the mounting recess 41, and the second fastening means 7 are located in the hole of the optically transparent diffuser 2. This connection method can reduce the difficulties associated with mounting and dismounting, and increase the speed of mounting and dismounting.

[0033] In this embodiment, the width direction of the protrusion 4 coincides with the width direction of the mounting part 1. The first fastening means 6 are located on both sides of the protrusion 4 in the width direction of the mounting part 1. The second fastening means 7 are located on two opposite sides of the opening of the diffuser 2.

[0034] Additionally, each of the first fastening means 6 is a groove structure formed by bending the outer wall of the protrusion 4 in the direction of the mounting recess 41. The groove structure is adjacent to the groove of the mounting recess 41. Namely, the first fastening means 6 and the protrusion 4 are made for one whole. Each of the second fastening means 7 is a hook-shaped structure located in the hole of the diffuser 2. The hook-shaped structure extends towards the center of the hole. Namely, the second fastening means 7 and the diffuser 2 are made in one piece. When assembling the diffuser 2 and the protrusion 4, the opening of the diffuser 2 is aligned with the protrusion 4, and then the diffuser 2 is pressed. The hole of the diffuser 2 is pressed, ensuring the movement of the hook-like structures to the groove structures and interaction with them. After eliminating the external force, the diffuser 2 returns to its original state. At this point, the hook and groove structures are in a tight fit state, thereby ensuring that the diffuser 2 is tightly attached to the protrusion 4.

[0035] Naturally, the design of the fastening assembly is not limited to constructively making the hook and groove connection of the aforementioned embodiment, it can also be made in the form of a joint consisting of bulges and grooves and the like.

[0036] In another preferred embodiment of the proposed utility model, the optically transparent diffuser extends along the longitudinal direction of the mounting portion along the length and forms a closed covering structure. According to the aforementioned structural solution, the diffuser 2 can be finally formed in the form of a hollow structure similar to a mounting frame, thereby providing an increase in the luminous region of the lighting device.

[0037] Naturally, the design of the diffuser 2 is not limited to the closed covering structure of the aforementioned embodiments, it can also be made in the form of segmented structures. For example, a plurality of optically transparent small diffusers can be placed at a mounting portion 1 along its longitudinal direction. Under each such small diffuser there are located a corresponding panel 3 and a light emitting element 5. In this case, it is possible to realize various types of lighting devices.

[0038] In one embodiment, a cavity 42 is formed between the bottom of the mounting recess 41 and the mounting surface 11 within the protrusion 4. The cavity 42 is made to reduce the total weight of the lighting device. In addition, the heat dissipation from the lighting panel 3 can be improved and the heat transfer from the panel 3 to the mounting surface 11 of the mounting part 1 can be reduced. As a rule, a power source can be located on the mounting part 1. In accordance with the aforementioned design solution, heat transfer from the panel 3 or from the power supply can be reduced to ensure that all components can operate normally.

[0039] In another embodiment, FIG. 3 is a schematic perspective view of a lighting device in accordance with another embodiment of the proposed utility model, and FIG. 4 is a schematic cross-sectional view of a lighting device in accordance with another embodiment of the proposed utility model. . In accordance with Fig. 4, the side of the mounting part facing away from the protrusion 4 is provided with a receiving recess 12 in which a power source 8 is located, electrically connected to the panel 3. The power source 8 can provide electricity for the panel 3 and the light emitting element 5. For in order not to occupy the light-emitting regions of the panel 3, the power supply 8 can be located on the back side of the mounting part 1, namely, on the side facing away from the protrusion 4. Additionally, by means of the mounting recess 41, the power supply 8 and the mounting frame can be mounted as a whole, so that the user does not have to attach the power source 8 separately during installation of the lighting device, thereby reducing the difficulty encountered during installation.

[0040] The side of the mounting part 1, facing away from the protrusion 4, is provided with two plates 13 located, respectively, on both sides in the width direction of the mounting part 1, while the two plates 13 define a housing recess 12. According to the aforementioned design the thickness of the entire mounting part 1 can be reduced to save material and reduce the weight of the entire lighting device.

[0041] The power source 8 and the receiving recess 12 may be secured using an additional device or bolts, or the like. It should be noted that the presented embodiment is not limited to a specific method of attaching a power source 8.

[0042] To protect against external influences on the power source 8, a removable partition may be located on the groove of the receiving recess 12. Various methods of disconnection can be used for the partition. For example, the partition is attached to the plates with 13 screws.

[0043] In this description, terms such as “embodiment” and “example” mean that specific properties, structures, material or characteristics described in accordance with embodiments are included in at least one embodiment or example of a proposed utility model . In this description, the appearance of various formulations, such as “embodiment,” “one embodiment,” or “certain embodiments,” is not necessarily all referring to the same embodiments. In addition, the described specific properties, structures, materials or characteristics may be combined in a suitable manner in any of one or more embodiments or examples.
