In view of the problems in the prior art, the present application aims to provide an illumination lamp with an improved heat dissipation structure, so as to achieve a better heat dissipation effect.

As shown in fig. 1, a schematic view of a combined structure of an illumination lamp 1 in the embodiment of the present application is shown.

As shown in the drawings, the illumination lamp 1 includes a housing 11, and as can be seen from fig. 2, the housing 11 has an opening 111, and the opening 111 forms an accommodating space inward. The accommodating space is provided for arranging the light source carrier 12, the connecting member 13, the circuit part 14 and the like, and the opening 111 is used for emitting light from the light source part 121.

In fig. 1, the opening 111 is filled with a light-transmitting cover 15 of the illuminating lamp 1 for transmitting light; as can be seen from fig. 1, the light-transmitting cover 15 is provided with a recess 151, which is located in the middle of the light-transmitting cover 15 in this embodiment, and a third penetrating portion 152 in the form of a hollow, a hole, or the like is formed in the recess 151 to communicate the accommodating space with the space outside the housing 11, so as to enhance heat dissipation.

In this embodiment, optionally, the irradiation lamp 1 is in the form of a down lamp, and two opposite sides of the housing 11 are provided with elastic mounting members 16 for being clamped against a surface of a position to be set to mount the irradiation lamp, for example, a handle connected to a torsion spring is shown in the figure.

The resilient mounting 16 is capable of resilient return movement at least in a direction towards the housing 11.

Specifically, when the handle is inward close to the housing 11, the torsion spring rotates and deforms to generate resilience, so that the irradiation lamp 1 can be plugged into the mounting hole, then the torsion spring is released to enable the irradiation lamp to automatically rebound, the handle is pressed against the surfaces on two sides of the mounting hole, the irradiation lamp 1 cannot be taken out, and the installation is completed. In general, the central axis of the mounting hole is vertical, and the irradiation lamp 1 applies force to the handles on both sides by its own weight to complete the mounting.

Optionally, one or more hollow portions 112 may be further disposed on the surface of the housing 11 to communicate the accommodating space therein with the outside of the housing 11, so as to enhance heat dissipation.

Referring to fig. 2, fig. 2 is an exploded schematic view of an illumination lamp 1 according to an embodiment of the present disclosure.

In fig. 2, the illumination lamp 1 is shown to include a housing 11 and a light-transmissive cover 15; it is also shown that the illumination luminaire 1 comprises: a light source carrier 12, a connecting member 13, and a circuit member 14 provided in the accommodating space.

As shown in fig. 2 and 4, in order to position the light-transmissive cover 15 and the housing 11, in the present embodiment, the inner surface of the housing 11 is provided with a first combining portion 113, and the surface of the light-transmissive cover 15 is provided with a second combining portion 153 combined with the first combining portion 113 to position the light-transmissive cover 15 and the housing 11. The first and second coupling portions 113 and 153 are one and the other of a concave portion and a convex portion, respectively, which are fitted to each other; in this embodiment, the first coupling portion 113 is a concave portion, and the second coupling portion 153 is a convex portion.

The light source carrier 12, which is disposed in the accommodating space, has a light source part 121 disposed on a first surface facing the opening 111.

In some embodiments, the light source part 121 includes a packaged LED chip. The first surface may be uniformly provided with a plurality of LED chips in a circumferential direction.

Wherein, the second surface which forms a front and a back with the first surface faces the containing space, and the light source carrier 12 is further provided with a first penetrating part 122 which penetrates through the first surface and the second surface.

in this embodiment, the first penetrating portion 122 is a through hole disposed in the middle of the light source carrier 12.

Referring to fig. 3, in the present embodiment, after the light-transmitting cover 15 is installed, a light source cavity 17 for accommodating the light source component 121 is formed between the housing 11 and the first surface of the light source carrier 12, and the third penetrating portion 152 is disposed at the bottom of the recess 151 of the light-transmitting cover 15 and is communicated with the accommodating space, but is not communicated with the light source cavity 17, that is, the third penetrating portion 152 may be disposed on a portion of the light-transmitting cover 15 other than the portion constituting the light source cavity 17; this is advantageous in protecting the light source chamber 17 from being hermetically sealed and preventing water, dust, etc. from entering the light source chamber 17 to impair illumination.

Optionally, to further enhance the sealing performance of the light source cavity, a sealing member 18 may be further disposed in the light source cavity 17 for sealing the connection position between each two of the light source carrier 12, the housing 11, and the light transmissive cover 15.

In this embodiment, as shown in fig. 3, the third combining portion 181 of the sealing member 18 is a flange formed at one end thereof, and the fourth combining portion 114 is a matching groove disposed on the inner wall of the housing 11, in this embodiment, the shape of the flange and the shape of the groove are both annular due to the requirement of matching the cross section of the housing 11 to be circular, and after combining the two, both sealing and positioning in the translation direction of the sealing member 18 are achieved.

Since the cross section of the housing 11 may be circular, in order to prevent the sealing member 18 from rotating, optionally, as shown in fig. 2 and 4, a first positioning portion 182 may be formed on the sealing member 18, and a second positioning portion 115 may be formed on an inner wall of the housing 11, that is, one and the other of the positioning hole and the positioning post may be respectively provided, and the rotation direction of the sealing member 18 may be positioned by passing through the positioning hole and the positioning post.

Alternatively, the first positioning portion 182 is disposed along the depth direction between the opening 111 of the housing 11 and the bottom of the accommodating space, i.e. the longitudinal direction in the drawing, which is advantageous in that, since the light source carrier 12, the sealing member 18, the connecting member 13, etc. are all inserted from the opening 111 along the depth direction of the accommodating space, the direction of the first positioning portion 182 is adapted to the installation direction, and when the sealing member 18 is inserted into the light source cavity 17 from the opening 111, the second positioning portion 115 can be naturally aligned and naturally combined without other adjustment operations, and the installation is convenient.

the connecting member 13 has a third surface facing the second surface and a fourth surface opposite to the third surface.

A power supply cavity 19 is formed between the fourth surface and the housing 11 for the arrangement of the circuit component 14.

One or more second penetrating portions 132 may be further disposed on the connecting member 13 to penetrate through the third and fourth surfaces, so as to communicate with the first penetrating portion 122, and communicate with the third penetrating portion 152, so as to communicate the power supply cavity 19 with the outside; particularly, after the hollow portion 112 communicated with the power supply cavity 19 is disposed on the housing 11, the hollow portion 112 is also communicated with the outside of the housing 11 and the power supply cavity 19, so as to form an airflow path of "outside- > third penetrating portion 152- > second penetrating portion 132- > power supply cavity 19- > hollow portion 112- > outside", which is beneficial for heat dissipation.
