[0002] LED luminous efficiency refers to the ratio of the luminous flux emitted by a light source to the electrical power it consumes, with the unit of lm / W. Specifically, LED luminous efficiency is the value obtained by dividing the luminous flux (lm) emitted by a light source by the electrical power (W) consumed by the light source.

[0003] Ways to improve LED lighting efficiency include: optimizing optical design, such as selecting high-quality light guide plates and reflective paper, which can improve light utilization and reduce light loss; controlling the working environment: controlling the working environment temperature and humidity to avoid the effects of overheating and excessive humidity on lighting efficiency, etc.

[0004] It is difficult to achieve accurate heat dissipation in existing LED lamp module designs, and the heat dissipation structure is relatively traditional and difficult to adapt to modular design. Summary of the invention

When the main body of the LED lamp is inserted into the through hole, its rear end is against the inside of the electrode groove and the two contacts are in contact with the electrode sheet 10 respectively to supply power to the LED lamp. After continuing to insert inward, the magnetic block 13 is finally attracted by the magnet and maintains the attracted position. At this time, the LED lamp is in a power supply state.

[0024] A number of heat dissipation fins 14 are provided on the side of the LED body. Due to the design of the heat dissipation fins, there is a gap between the through hole and the LED body. The side of the cavity is connected to the outlet of the air cooling device. The cold air of the air cooling device enters the cavity and then enters the lamp trough through the through hole and is then discharged. In this process, the cold air passes through the heat dissipation fins to dissipate the heat of the LED body, ensuring that it is at a suitable temperature for a long time to avoid excessively high temperature affecting the light effect.

[0025] The heat dissipation fins are distributed in a ring shape on the side of the LED body and a slope 20 is provided at the inner end.

[0026] An arc-shaped reflective sheet 15 is arranged in the lamp trough, and the light emitted by the light-emitting part of the LED lamp can be reflected by the reflective sheet to better improve the light effect.

[0027] A transparent plate 16 is arranged on the front side of the mounting strip, and the opening of the lamp trough is sealed by the transparent plate 16 to realize the function of a lampshade; an air groove 17 is arranged on the front side surface of the mounting strip corresponding to one side of the lamp trough, and the air groove 17 is connected to the outside; an air hole 18 is arranged between the air groove 17 and the lamp trough; a shielding piece 19 is arranged at one end of the air hole in the air groove; the shielding piece is made of elastic material and one end of the shielding piece is fixedly connected to the side of the air hole; the air hole can be closed under the elastic action of the shielding piece itself; when air enters the lamp trough, it can enter the air groove through the air hole and then be discharged to the outside; the shielding piece functions as a one-way valve, and has a simple structure and low cost.

[0028] When the LED lamp is taken out, the sealing plate automatically closes the inner end of the corresponding through hole under the action of the spring, and the cold air in the cavity can only enter the through hole where the LED lamp is installed to dissipate the heat, so that air can only enter the through hole where the LED lamp is installed. After the LED lamp is installed, the installation and electrode connection can be automatically achieved through the attraction of the magnet. The installation is convenient and quick. The device can be modularly combined, and multiple devices can be combined into various shapes. The number of LED lamps installed in each device is also installed according to specific circumstances. The amount of cold air entering for heat dissipation can be adjusted according to the total number of LED lamps to achieve energy-saving heat dissipation.

[0029] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention.
