Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

Example 1

With reference to Figures 1-2, this embodiment provides a structural waterproof lamp assembly with a waterproof rating of IP68. It comprises a lamp cover 1, and the lamp cover 1 has a lamp installation cavity 2 which can be closed; the lamp installation cavity 2 is provided with a lamp board assembly 4, and the lamp cover 1 has a light transmission for transmitting the light at the lamp board assembly 4. There is an assembly port at the lamp installation cavity 2, and a sealing component is arranged at the assembly port; a heat dissipation component is arranged in the lamp installation cavity 2, and the heat dissipation component is used to transfer the heat from the lamp board assembly 4 to the sealing assembly.

In this embodiment, by directly disposing the lamp installation cavity 2 at the lamp cover, and sealing the assembly opening of the lamp installation cavity 2 through the sealing component, the structural seal of the lamp installation cavity 2 can be preferably formed.

IP68 is the highest level of enclosure protection, which means that the dustproof level can completely prevent the intrusion of foreign objects and dust, and the waterproof level can ensure that the electrical appliance is submerged indefinitely under the specified water pressure to ensure that it will not be damaged by water immersion. Most of the existing outdoor lamps are waterproof by means of structural waterproofing or material waterproofing.

Existing lamps with waterproof materials are affected by the service life of the glue-filling layer and the gap between the glue-filling layer and the lamps, so it is difficult to achieve IP68 protection. Existing lamps with a waterproof structure have too many gaps between the panels, housings and plugs of the lamps, so it is difficult to achieve IP68 protection.

In the lamp in this embodiment, since the gap between the lamp board assembly 4 and the outside world only exists at the assembly port, and the assembly port is sealed by the sealing assembly, the sealing of the lamp installation cavity 2 can be better achieved, so the lamp installation cavity 2 can be better sealed. Ideally achieve IP68 protection.

In this embodiment, the heat dissipation component is provided, so that the heat at the lamp board assembly 4 can be preferably dissipated from the sealing assembly, so that the heat dissipation of the lamp installation cavity 2 can be better achieved.

Those skilled in the art can understand that the lamp board assembly 4 described in this embodiment is the light emitting assembly of the lamp. The light board assembly 4 can include, for example, a PCBA circuit board. For example, a control chip can be set in the PCBA circuit board. At the same time, a plurality of LED lamp beads can be set on the PCBA circuit board, and the on-off control of the LED lamp beads can be realized through the control chip. . Wherein, the power cord between the lamp board assembly 4 and the outside can also pass through the sealing assembly.

In addition, in another embodiment different from this embodiment, each LED lamp bead is provided with a lens 5 correspondingly. Therefore, the condensing property of the light beam can be better improved.

In addition, the lamp cover 1 can be configured into various shapes, so it can better meet the requirements of different lighting scenarios. For example, the lamp cover 1 can be configured in a long strip shape, so it can preferably form a strip light; the lamp cover 1 can also be configured in a ring shape, so a circular lamp cover 1 can be preferably formed by, for example, a plurality of concentric rings. such as floodlights.

Wherein, it can be understood that the lamp cover 1 can have an extension direction, and the extension direction of the lamp installation cavity 2 can be consistent with the extension direction of the lamp cover 1 . At the same time, the extension direction of the lamp board assembly 4 can also be consistent with the extension direction of the lamp installation cavity 2 , especially the overall array direction of all LED lamp beads at the lamp board assembly 4 can be consistent with the lamp installation cavity 2 . Based on this structure, the installation of the lamp panel assembly 4 in the lamp installation cavity 2 can be preferably realized. At the same time, it can be known without any doubt that the extending direction of the light-transmitting area can also be consistent with the overall array direction of all the LED lamp beads, so that the light penetration can be better achieved.

In addition, the lamp cover 1 can be an integral structure, and the light-transmitting area can be directly formed by the corresponding part at the lamp cover 1 , or can be added to the lamp cover 1 . However, it should be noted that, in order to ensure the overall protection performance, it is better that the light-transmitting area is integrally provided at the lamp cover 1 .

In this embodiment, the present invention is described by taking the example that the light-transmitting region is integrally provided at the lamp cover 1 . In order to construct the light-transmitting area, the entire material of the lamp cover 1 can be made of a light-transmitting material such as glass, plastic, etc. In this case, the whole of the lamp cover 1 is a light-transmitting area. Of course, in order to adjust the irradiation area of light, although the lamp cover 1 is made of light-transmitting material as a whole, the structure of the light-transmitting area can also be realized by arranging a light-shielding layer.

In order to explain the present invention, in this embodiment, the lamp cover (1) is constructed in a long strip shape as an example for explanation.

In addition, it should be noted that the outer shape of the cross-section of the lamp cover 1 can be formed into various shapes, such as circle, square, triangle, pentagon, special shape, etc. as required.

At the same time, it can be understood that the shape of the cross section of the lamp installation cavity 2 can also be formed into various shapes according to requirements, such as a circle, a square, a triangle, a pentagon, a special shape, and the like.

In order to explain the solution of the present invention more simply, in this embodiment, the outline shape of the cross section of the lamp cover 1 and the cross section shape of the lamp installation cavity 2 are both circular for explanation.

In this embodiment, the cross-sectional shape of the lamp installation cavity 2 is circular, so that the sealing component can preferably use the form of a shaft seal to seal the lamp installation cavity 2, so it can be better ensured that it can reach the IP68 degree of protection. It can be understood that, the sealing of the sealing assembly is preferably achieved as described herein by setting the inner cross-section of the assembly port to be circular. At the same time, for an assembly port of the same cross-sectional area, when the inner cross-section of the assembly port is set to be circular, the inner surface area of the assembly port is also the smallest, so the area of the sealing surface can also be preferably reduced, thereby improving the sealing performance.

In addition, the lamp cover 1 in this embodiment can be in the shape of a hollow column as a whole, a lamp installation cavity 2 can be formed inside the lamp cover 1, and one end or both ends of the lamp installation cavity 2 can form an assembly opening. Therefore, the assembly of the lamp board assembly 4 and the sealing of the lamp installation cavity 2 can be preferably achieved.

Wherein, when only one end of the lamp installation cavity 2 is provided with an assembly port, the communication gap between the lamp installation cavity 2 and the outside can be preferably reduced, so the protection performance can be better improved.

Wherein, when both ends of the lamp installation cavity 2 are provided with assembly openings, the combined use of a plurality of lamp covers 1 can be better facilitated, and the heat dissipation performance can be better improved.

In this embodiment, the length of the lamp cover 1 can be, for example, 100-400 mm, and the inner diameter of the lamp installation cavity 2 can be, for example, 10-100 mm. Therefore, the size requirements of the existing lamps can be better satisfied. Wherein, when the inner section of the lamp installation cavity 2 is not circular, the inner diameter of the lamp installation cavity 2 can be the diameter of its inscribed circle.
