Description

Technical Field

[0001] This utility model relates to LED lighting fixtures, specifically disclosing a lamp housing for a strip chandelier and a strip chandelier using the lamp housing. Background Technology

[0002] Strip pendant lights, also known as office pendant lights, mainly consist of a lamp housing made of aluminum profiles, with an LED light source installed inside. The light outlet of the lamp housing has a panel to prevent glare. This panel can be a diffuser, an anti-glare grille, or an anti-glare lamp cup module, etc. Because the installation structures of various panels differ, manufacturers need to produce lamp housings with different structures for each type of panel for the same strip pendant light design. This increases the variety and cost of molds for the aluminum profiles used in the lamp housing, and also increases the inventory variety for both manufacturers and retailers. Utility Model Content

[0018] To further understand the features, technical means, specific purposes, and functions of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. The descriptions of component positions (including but not limited to: upper, lower, inner, outer, left, right, etc.) are for reference only when referring to the positions of the components shown in the accompanying drawings. Their purpose is to facilitate understanding of the relative relationships between the components and does not represent an absolute limitation on the scope of protection of this utility model. Those skilled in the art will understand that the description of relative positions may change when the view direction changes, but the essential relative positional relationships between the components remain unchanged.

[0019] refer to Figure 1 and Figure 2 A strip pendant light housing includes a light source cavity 1 located on the front of the housing and a power supply cavity 2 located on the back of the housing. The light source cavity 1 is U-shaped and includes a bottom wall 11, side walls 12 located on both sides of the bottom wall, and a light outlet 10 opposite to the bottom wall 11. Near the light outlet 10, the two side walls 12 are provided with a first mounting groove 101, a second mounting groove 102, a third mounting groove 103, and a fourth mounting groove 104 arranged sequentially from the outside to the inside, wherein the outermost side wall 13 of the first mounting groove 101 is longer than the side walls of the other mounting grooves. That is, the outermost side wall of the first mounting groove 13 extends into the light source cavity 11 with a length greater than the length of its inner side wall and the side walls of the second to fourth mounting grooves. A main lamp plate mounting groove 105 is provided at the bottom of the light source cavity 11, and a plurality of heat dissipation grooves 106 are provided at the bottom of the main lamp plate mounting groove 105. The power supply cavity 2 has a U-shaped cross-section, with an end cap mounting groove 201 and reinforcing ribs 22 supporting the bottom wall 11 of the light source cavity on its inner side wall. An auxiliary lamp plate mounting groove 202 is located at the center of the outer side of the back of the power supply cavity 2, and fastening grooves 203 are provided on both sides of the auxiliary lamp plate mounting groove 202. The fourth mounting groove 104 and the end cap mounting groove 201 are preferably circular, allowing them to be screwed into place to secure the end cap. The lamp housing is preferably made of aluminum profile, allowing for arbitrary cutting to the required length during manufacturing, further reducing the variety of items in inventory.

[0020] refer to Figure 3A strip chandelier using the aforementioned lamp housing further includes an LED light source 3, which comprises a lamp plate 31 and LED beads 32 mounted on the lamp plate 3. The LED light source 3 is fixed in the main lamp plate mounting groove 105 by the lamp plate 31. The same LED light source 3 can also be installed in the auxiliary lamp plate mounting groove 202. A diffuser plate 4 is also included, which is snapped into the first mounting groove 10. Since the outer wall 13 of the first mounting groove 101 is longer than the sidewalls of other mounting grooves, this extension prevents light leakage and makes the boundary of the light-emitting surface of the diffuser plate 4 clearer.

[0021] refer to Figure 4 and Figure 5 A strip chandelier using the aforementioned lamp housing further includes an LED light source 3, which comprises a lamp plate 31 and LED beads 32 mounted on the lamp plate 3. The LED light source 3 is snapped into the main lamp plate mounting groove 105 via the lamp plate 31. The same LED light source 3 can also be installed in the auxiliary lamp plate mounting groove 202. It also includes a grille plate 5, with retaining strips 51 provided on the lower sides of both sides. The grille plate 5 can be as follows... Figure 4 The honeycomb grid panel shown is provided with a honeycomb grid pattern, or as... Figure 5 The diagram shows a strip grid panel 5 with a strip-shaped grid. The lower side of the grid panel 5 is engaged in the first or second mounting groove by the locking strip 51, and its upper side abuts against the inner side of the outer side wall 13 of the first mounting groove, thereby fixing it to the light outlet. Since the honeycomb grid panel is thinner, its locking strip 51 can be engaged in the first mounting groove 101; while the strip grid panel is thicker, its locking strip 51 is engaged in the second mounting groove 102. Since the outer side wall 13 of the first mounting groove 101 is longer than the side walls of the other mounting grooves, this extension can be used to limit the upper side of the grid panel 5 on the one hand, and to prevent light leakage on the other hand, making the boundary of the light-emitting surface of the grid panel 5 clearer.

[0022] refer to Figure 6 A strip chandelier using the aforementioned lamp housing also includes an LED light source 3, which comprises a lamp plate 31 and LED beads 32 mounted on the lamp plate 3. The LED light source 3 is fixed in the main lamp plate mounting groove 105 by the lamp plate 31. Similarly, the same LED light source 3 can also be installed in the auxiliary lamp plate mounting groove 202. It also includes a deep anti-glare lamp cup 6, with retaining strips 61 on both sides of the upper edge of the lamp cup. The upper side of the lamp cup 6 is secured in the first mounting groove 101 by the retaining strips, and its lower side abuts against the lamp plate 31 or the bottom wall 11 of the light source cavity for fixation. Since the outer wall 13 of the first mounting groove 101 is longer than the side walls of other mounting grooves, this extension prevents light leakage and concentrates the light emitted from the lamp cup.

[0023] refer to Figure 7 and Figure 8 The installation structure of this utility model includes a lamp housing, a fastener 7, and a suspension wire 8. The fastener 7 is fastened into the fastening groove 203 on the back of the lamp housing, and one end of the suspension wire 8 is connected to the fastener 7, while the other end is fixed to the ceiling.

[0024] This utility model has a first to Nth mounting groove provided from the outside to the inside on both sides of the light outlet of the lamp housing, and the outer side wall of the first mounting groove is longer than the side wall of the other mounting grooves. The multiple mounting grooves can be used for various anti-glare panels, including diffuser plates, grille plates and lamp cups. It has strong versatility and can greatly reduce the mold cost of the lamp housing and reduce the types of inventory in production and sales.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
