[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] The technical problem addressed in this embodiment is that while existing all-aluminum profile lamp holders offer a more upscale appearance, the fluctuating price of aluminum profile raw materials and high mold-making costs make it difficult to amortize costs during large-scale production, resulting in a high overall cost for the lamps. Furthermore, the heavy weight of aluminum profiles leads to significant load-bearing during transportation, installation, and use, making it difficult to achieve a balance between performance, cost, and lightweight design in elongated surface light source lamps. Therefore, reducing the amount of aluminum used in the lamp holder to lower lamp costs is a challenging technical issue facing the industry.

[0030] To solve the above-mentioned technical problems, this embodiment provides a plastic lamp holder, such as... Figure 1 , Figure 2As shown, it includes: a lamp head housing 10, the lamp head housing 10 including a receiving cavity 11 for accommodating a light-emitting unit, the lamp head housing 10 having a first slot structure in the receiving cavity 11, the light-emitting unit having a second engaging structure adapted to the first slot structure, the light-emitting unit being connected to the lamp head housing 10 through the second engaging structure and the first slot structure; a light-emitting unit, the light-emitting unit including a drawn aluminum profile 20, a reflector 30 and a lamp plate 40, the reflector 30 and the lamp plate 40 being fixable to the drawn aluminum profile 20, the drawn aluminum profile 20 including the second engaging structure; and a light guide plate 50, the light guide plate 50 being fixed to the lamp head housing 10 and / or the light-emitting unit.

[0031] The lamp head housing 10, the aluminum profile 20, the lamp plate 40, the reflector 30, and the light guide plate 50 are essential components of the lamp head. How to rationally design these essential components and how to assemble them are technical directions that lighting manufacturers need to continuously optimize. In this embodiment, we provide a new type of lamp head that separates the lamp head housing 10 from the light-emitting unit, so that the lamp head housing 10 and the aluminum profile 20 can be manufactured separately. A lighter and cheaper lamp head housing 10 can be used to reduce the overall production cost of the lighting fixture. At the same time, the cooperation of the first slot and the second engaging structure enables convenient production of the light-emitting unit and the lamp head housing 10, ensuring the efficiency of production and manufacturing.

[0032] Specifically, the lamp head housing 10 is a plastic housing, and the aluminum profile 20 is an aluminum profile. The aluminum profile 20 provides a rigid support structure for the main components of the lamp. At the same time, the aluminum profile 20 is also the location where the lamp plate 40 and reflector 30, where heat is concentrated, are set. The aluminum profile 20 ensures good heat dissipation performance of the lamp plate 40, reflector 30 and the main light path area. The external support of the lamp head housing 10 is made of plastic, which can effectively reduce the production cost of the lamp. At the same time, the plastic housing has better plasticity than the aluminum profile.

[0033] Specifically, the lamp head housing 10 is divided into a long side direction and a short side direction according to the elongated light guide plate 50. The lamp head housing 10, the light-emitting unit and the light guide plate 50 are all arranged along the long side direction during assembly. The lamp head housing 10 has an opening in the long side direction. The light-emitting unit and the light guide plate 50 can be inserted and installed in the lamp head housing 10 on one side of the opening on the long side, which not only ensures quick and efficient assembly but also ensures the overall stability of the lamp head.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, the first slot structure and the second engaging structure include:

[0035] The first slot structure of the lamp holder housing 10 includes an upper slot 121, a lower slot 122, and a side slot 123. The upper slot 121 is disposed on the upper wall plate of the lamp holder housing 10, the lower slot 122 is disposed on the lower wall plate of the lamp holder housing 10, and the side slot 123 is disposed on the side wall plate of the lamp holder housing 10. The second engagement structure of the pull aluminum profile 20 includes an upper engagement head 221 adapted to the upper slot 121, a lower engagement head 222 adapted to the lower slot 122, and a side engagement head 223 adapted to the side slot 123. The pull aluminum profile 20 is fixed to the lamp holder housing 10 by inserting the upper engagement head 221, the lower engagement head 222, and the side engagement head 223 into the upper slot 121, the lower slot 122, and the side slot 123 of the lamp holder housing 10.

[0036] The three-directional locking structure ensures a stable connection between the lamp holder housing 10 and the aluminum profile 20. Obviously, other similar locking structures also fall within the scope of protection of this application, such as single-directional locking structures, two-directional locking structures, non-three-directional three-locking structures, and other similar locking structures.

[0037] Specifically, the aluminum profile 20 includes a lamp plate support back plate 23 and a lamp plate slot 231 for mounting the lamp plate 40. The lamp plate 40 is inserted into the lamp plate slot 231 through the opening of the lamp head housing 10 and fixed on the lamp plate support back plate 23. The aluminum profile 20 also includes a reflector support back plate 21 for mounting the reflector 30, and the reflector support back plate 21 has an arcuate surface consistent with the reflector 30.

[0038] Specifically, the light guide plate 50 is inserted into and fixed to the lamp head housing 10 through the opening of the lamp head housing 10 via the first light guide plate slot 24 and the second light guide plate slot 14. The first light guide plate slot 24 is disposed on the lamp head housing 10, and the second light guide plate slot 14 is disposed on the aluminum profile 20. Obviously, other possible arrangements are also within the scope of protection of this application, such as disposing of the light guide plate 50 on the lamp head housing 10, disposing of the light guide plate 50 on the aluminum profile 20, or other possible arrangements.

[0039] Example 2
