Detailed Description

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

Example 1

As shown in connection with fig. 1-2, the present embodiment provides a structural waterproof light assembly that is rated waterproof up to IP 68. The lamp comprises a lamp cover 1, wherein a closable lamp installation cavity 2 is arranged in the lamp cover 1; a lamp panel component 4 is arranged in the lamp mounting cavity 2, and a light transmitting area for transmitting light rays at the lamp panel component 4 is arranged at the lamp cover 1; an assembly opening is formed in the lamp installation cavity 2, and a sealing assembly is arranged at the assembly opening; set up radiator unit in lamps and lanterns installation cavity 2, radiator unit is used for the heat transfer to seal assembly department with lamp plate assembly 4 department.

In this embodiment, the lamp mounting cavity 2 is directly disposed at the lamp cover, and the assembly opening at the lamp mounting cavity 2 is sealed by the sealing component, so that the structural seal of the lamp mounting cavity 2 can be better formed.

IP68 is the highest level of protection of the housing, which means that the dust-proof level can completely prevent the invasion of foreign objects and dust, and the waterproof level can ensure that the electrical appliance is not damaged by water immersion when the electrical appliance is submerged under the specified water pressure for an indefinite period. The existing outdoor lamp is mostly waterproof by adopting a structural waterproof or material waterproof mode, the structural waterproof is realized by utilizing a physical structure, and the material waterproof generally comprises glue filling and water proofing.

The existing lamp adopting the waterproof material is influenced by the service life of the glue filling layer and the gap between the glue filling layer and the lamp, so that the IP 68-grade protection is difficult to realize. The existing lamp adopting a waterproof structure has too many gaps among a panel, a shell and a plug of the lamp, so that the protection of IP68 grade is difficult to realize.

In the lamp in this embodiment, since the gap between the lamp panel assembly 4 and the outside is only present at the assembly opening, and the sealing assembly seals the assembly opening, the sealing of the lamp installation cavity 2 can be preferably achieved, so that the protection of IP68 grade can be preferably achieved.

In this embodiment, through setting up radiator unit, so make the heat of lamp plate subassembly 4 department can distribute from seal subassembly department better, so can realize the thermal heat dissipation to lamps and lanterns installation cavity 2 better.

As will be understood by those skilled in the art, the light panel assembly 4 in the present embodiment is a light emitting assembly of a lamp. Wherein, lamp plate subassembly 4 can include for example the PCBA circuit board, can establish for example control chip in the PCBA circuit board, can establish a plurality of LED lamp pearls on the PCBA circuit board simultaneously, can realize the on-off control to LED lamp pearl through control chip. Wherein, lamp plate assembly 4 also can wear out from the subassembly with the power cord between the external world.

In addition, in another embodiment different from the present embodiment, a lens 5 is correspondingly disposed at each LED lamp bead. The pinching of the light beam can be preferably improved.

In addition, the lamp cover 1 can be configured in various shapes, so that different lighting scene requirements can be better met. For example, the lamp cover 1 can be configured in a strip shape, so that a strip lamp can be preferably formed; the lamp cover 1 can also be designed in the form of a ring, so that a circular, for example, projection lamp can preferably be formed by a plurality of concentrically arranged lamp covers 1.

Wherein, it can be understood that the lamp cover 1 can have an extending direction, and the extending direction of the lamp mounting cavity 2 can be consistent with the extending direction of the lamp cover 1. Simultaneously, the extending direction of lamp plate assembly 4 also can keep unanimous with the extending direction of lamps and lanterns installation cavity 2, and especially the whole array direction of all LED lamp pearls of lamp plate assembly 4 department can keep unanimous with lamps and lanterns installation cavity 2. Based on this kind of structure, can realize the installation of lamp plate assembly 4 in lamps and lanterns installation cavity 2 better. Meanwhile, it can be known without any doubt that the extending direction of the light-transmitting area can be consistent with the overall array direction of all the LED lamp beads, so that light can be better transmitted.

In addition, the lamp cover 1 may be an integral structure, and the light-transmitting region may be directly formed by a corresponding portion of the lamp cover 1, or may be additionally installed at the lamp cover 1. However, it should be noted that, in order to ensure the overall protection performance, it is better to integrally arrange the light-transmitting region at the lamp cover 1.

In this embodiment, the light-transmitting area is integrally disposed on the lamp cover 1, which is taken as an example to explain the present invention. In order to construct the light-transmitting region, the material of the lamp cover 1 can be made of a light-transmitting material such as glass or plastic, and the whole lamp cover 1 is the light-transmitting region. Of course, although the lamp cover 1 is entirely made of a light-transmitting material in order to adjust the light irradiation region, the light-transmitting region can be configured by providing a light-shielding layer.

In order to explain the present invention, the present embodiment is explained by taking the case where the lamp cover (1) is formed in a long strip shape.
