It should be noted that, the second cavity 112 is not only the installation cavity and the heat dissipation cavity of the light source body 120, but also the second cavity 112 is a supporting cavity of the whole lamp 100, and because the lamp cover 110 needs to be installed with the light source body 120 and other parts, the lamp cover 110 has a certain strength requirement, and the thickness of the lamp cover 110 needs to reach a certain standard under the limitation of the strength requirement, so as to avoid the excessive wall thickness of the lamp cover 110 from affecting the overall weight of the lamp 100, at this time, the wall surface of the second cavity 112 penetrating axially can form a mechanical supporting effect on the lamp cover 110 to increase the overall structural strength, thereby eliminating the strict limitation on the wall thickness of the lamp cover 110.

According to the lamp 100 provided in the embodiment of the application, through the arrangement of the second cavity 112, the light source body 120 with the length being cut according to the requirement is inserted by utilizing the topological structure of the universality, so that the optical cavity is separated from the thermal cavity, the standardization and the universality of products with different sizes, shapes and textures under different environments are ensured, the limitation of technical requirements such as optical parameters, thermal properties and electrical paths can be effectively relieved, the diversified appearance, the structural strength requirement, the material cost requirement, the labor hour cost requirement and the like of the products are effectively integrated, and meanwhile, the second cavity 112 is multipurpose, the wall thickness of the lamp shade 110 is reduced, and the weight of the lamp 100 is reduced.

In this embodiment, as shown in fig. 1 to 4, the through hole 122 may be disposed at a first end of the heat sink 121, correspondingly, the connection structure 140 near the first end of the heat sink 121 may be a common single-stud bolt, and the connection structure 140 near the second end of the heat sink 121 may be a double-stud bolt, where the double-stud bolt has a wiring cavity passing through axially, and the double-stud bolt may be inserted into the support rod 150, the support rod 150 may be used to support the light source body 120, one end of the cable may pass through the air through channel and the through hole 122 to be electrically connected with the light source 128 on the substrate 127, and the other end of the cable may pass through the wiring cavity and be inserted into the support rod 150.

In some embodiments, as shown in fig. 4-7, the heat spreader 121 may be prismatic, the side edges of the heat spreader 121 may be provided with guard ribs 123, and the substrate 127 may be mounted between two adjacent guard ribs 123.

It will be appreciated that the prism may have a plurality of sides, each side may correspond to one substrate 127, each prism side between two sides may be provided with one protection rib 123, in other words, two bottom surfaces of the heat spreader 121 are each polygonal, the number of sides of the polygons is consistent with the number of the substrates 127, for example, in some embodiments, as shown in fig. 4-7, 6 substrates 127 are provided, correspondingly, two bottom surfaces of the heat spreader 121 are each hexagonal, and the side edges of the heat spreader 121 are provided with 6 protection ribs 123.

In practical implementation, as shown in fig. 4-7, if the side edges of the heat sink 121 are not provided with the protection ribs 123, when the lamp 100 is used for a long time and not overhauled, the bolts between the substrate 127 and the heat sink 121 may be loosened, at this time, the substrate 127 may be greatly displaced to affect the connection quality, even the substrate 127 may be out of contact with the heat sink 121, and when the lamp 100 is severely shaken or vibrated, the light source 128 on the substrate 127 may directly collide with the wall surface of the second cavity 112 to cause damage; in the case that the protective ribs 123 are disposed on the side edges of the heat sink 121, the protective ribs 123 may protrude outward in the radial direction, the substrate 127 may be disposed between the two protective ribs 123, and when the lamp 100 is severely shaken or vibrated, the protective ribs 123 on both sides may protect the light source 128 on the substrate 127, even if the bolts between the substrate 127 and the heat sink 121 are loosened, the substrate 127 and the heat sink 121 are not separated from contact.

According to the lamp 100 provided by the embodiment of the application, through the arrangement of the protective ribs 123, the protection effect on the substrate 127 and the light source 128 arranged on the substrate 127 under special working conditions is achieved, and the wiring quality of the light source body 120 under a long-term service period is ensured, so that the durability and the stability of the lamp 100 are enhanced.

In some embodiments, as shown in fig. 1-4, the second chamber 112 may include a main body section 113 and inlet sections 114 provided at both ends of the main body section 113, the main body section 113 may have an inner diameter smaller than that of the inlet section 114, and the light source body 120 may be mounted to the main body section 113.

It can be understood that if the second cavity 112 is a cylindrical cavity with a constant inner diameter along the axial direction, that is, the inner diameters of the main body section 113 and the inlet section 114 are the same, since the radiator 121 and the substrate 127 are mounted on the main body section 113, the air channel width of the radiator 121 is limited within the inner diameter range of the second cavity 112, the two ends of the radiator 121 have an air inlet and an air outlet, that is, hot air is emitted from the inlet section 114 at one end, cold air is absorbed from the inlet section 114 at the other end, and at this time, the inner diameter of the inlet section 114 is too small to cause the difficult emission of hot air in a short time, and meanwhile, the cold air cannot be rapidly absorbed into the air inlet channel.

Under the condition that the inner diameter of the main body section 113 is smaller than that of the inlet section 114, the radiator 121 and the base plate 127 are installed on the main body section 113, hot air is dispersed to the external environment through the inlet section 114 with one end with a larger inner diameter, meanwhile, cold air is sucked into the air duct through the inlet section 114 with the other end with a larger inner diameter, so that the radiator 121 can radiate heat at a higher speed, and the heat exchange effect is optimized.

In some embodiments, as shown in fig. 1-4, the luminaire 100 may further comprise: a spacer 130.

The wall surface of the lamp housing 110 may be formed with an outwardly facing stepped surface between the inlet section 114 and the main body section 113, the gasket 130 may be supported on the stepped surface, and the light source body 120 may be connected to the gasket 130.

It will be appreciated that if the gasket 130 is not supported on the step surface but is plugged in the main body section 113, the gasket 130 is only in interference fit with the wall surface of the second cavity 112 by virtue of elasticity thereof due to the clearance fit between the light source body 120 and the second cavity 112, so that the clearance between the light source body 120 and the second cavity 112 is blocked from both ends, and the sealing effect in the above manner obviously cannot meet the requirement.

Under the condition that the gasket 130 is supported on the step surface, at this time, the gasket 130 and the connecting structure 140 are both arranged on the inlet section 114, the light source body 120 is arranged on the main body section 113, the diameter of the gasket 130 is larger than the inner diameter of the main body section 113, the gasket 130 can be locked with the light source body 120 in a threaded connection manner through the connecting structure 140 and the connecting hole 126, so that moisture, dust and other impurities in the external environment are prevented from entering a gap between the light source body 120 and the second cavity 112, and the service life of the lamp 100 is prolonged.

In some embodiments, as shown in fig. 1-4, the gasket 130 may include: a sealing gasket 131 and a rigid gasket 132.

The sealing gasket 131 may be sandwiched between the rigid gasket 132 and the step surface.
