Referring to fig. 1 to 3, an embodiment of the present invention discloses a lighting fixture, which includes a housing 100 and a light source assembly 200.

The housing 100 is a base member of the lighting fixture, and the housing 100 can provide a mounting base for other components of the lighting fixture. In the embodiment of the present invention, the plurality of fins 110 are disposed at an interval in the first end of the casing 100, the light barrier 120 is disposed at the second end of the casing 100, and the light exit hole 121 is disposed on the light barrier 120. Specifically, the housing 100 may be an aluminum housing or a stainless steel housing, which is not limited in the embodiment of the present invention.

The Light source assembly 200 may be of various types, for example, a Light Emitting Diode (LED) Light source or a gas discharge Light source, which is not limited in the embodiments of the present invention. The light source assembly 200 is disposed in the housing 100, and an air channel 130 is formed between the light source assembly 200 and the inner surface of the housing 100, the air channel 130 is communicated with the light emitting hole 121, so that air can enter the housing 100 through the light emitting hole 121, and then flows out from the first end of the housing 100 through the air channel 130, thereby forming a complete internal convection path.

The light source assembly 200 faces the light exit hole 121, so that the light emitted from the light source assembly 200 is irradiated to a position to be illuminated through the light exit hole 121. And the light source assembly 200 is connected to the heat sink 110, and the heat sink 110 extends in a direction in which the second end points to the first end, so that heat generated by the light source assembly 200 is transferred to the heat sink 110, and the heat on the heat sink 110 can be dissipated out of the housing 100 through air flowing in the air passage 130, thereby better dissipating heat in the light source assembly 200, preventing the light source assembly 200 from being incapable of working normally due to high temperature, and further improving reliability of the light source assembly 200 and prolonging service life of the light source assembly 200.

The embodiment of the utility model discloses in the illumination lamps and lanterns, the interval is equipped with a plurality of fin 110 in the first end of casing 100, and the second end of casing is equipped with barn door 120, and fin 110 is connected with light source subassembly 200 to make the heat on the light source subassembly 200 can transmit to fin 110, and light source subassembly 200 sets up in casing 100, and forms gas passage 130 between the internal surface of light source subassembly 200 and casing 100, and gas passage 130 communicates with the light-emitting hole 121 of barn door 120. In this scheme, gas channel 130 can become the interior convection heat dissipation channel of illumination lamps and lanterns, and the air can be followed light-emitting hole 121 and got into in the illumination lamps and lanterns to carry out heat-conduction and heat radiation with the internal surface of illumination lamps and lanterns, flow out from the first end of casing 100 at last, thereby take away the partial heat of illumination lamps and lanterns, so that the heat in the illumination lamps and lanterns can directly be taken away, and then make the radiating efficiency of illumination lamps and lanterns higher. Meanwhile, the radiating fins can enlarge the radiating area and accelerate the radiating speed, so that the radiating efficiency of the lighting lamp can be further improved.

As described above, the plurality of heat dissipation fins 110 are spaced in the first end of the housing 100, and a heat dissipation channel is formed between any two adjacent heat dissipation fins 110, when the size of each heat dissipation channel is different from each other, more air passes through the larger heat dissipation channel, so that less air flows through the smaller heat dissipation channel, the heat dissipation effect of the smaller heat dissipation channel is poor, and the temperature distribution on the housing 100 is uneven. Based on this, in an alternative embodiment, the plurality of heat dissipation fins 110 may be disposed at equal intervals in the circumferential direction of the casing 100, so as to make the sizes of the heat dissipation channels equal, thereby making the volumes of the air passing through the heat dissipation channels equal, making the heat dissipation performance of the heat dissipation channels substantially equal, further making the temperature on the casing 100 uniformly distributed, and preventing the casing 100 from being deformed or damaged due to different thermal stresses on the casing 100 caused by non-uniform temperature distribution.

In the embodiment of the present invention, the light emitted from the light source assembly 200 can be irradiated to the position to be illuminated through the light exit hole 121, in order to intensively project the light emitted from the light source assembly 200 to the area to be irradiated by the light, thereby preventing the waste of light and energy, in an optional embodiment, the number of the light barriers 120 can be multiple, a plurality of light barriers 120 are all provided with the light exit hole 121, and the plurality of light barriers 120 are spaced in the light exit direction of the light source assembly 200. Under the circumstances, the light emitted by the light source assembly 200 passes through each light-emitting hole 121 in sequence, and the size of the beam angle can be conveniently controlled, so that the light emitted by the light source assembly 200 is projected to the area needing to be irradiated by the light in a concentrated manner, and the user experience of the lighting lamp is improved.

Specifically, the distance between two adjacent light-blocking panels 120 greatly affects the size of the beam angle, and thus, optionally, the distance between two adjacent light-blocking panels 120 may be adjusted, that is, the light-blocking panels 120 are movably disposed. In the actual use process of the user, the user can adaptively adjust the distance between two adjacent light barriers 120 according to actual requirements, so that the effect of adjusting the beam angle is achieved, the lighting lamp meets the requirements of different beam angles, and the universality of the lighting lamp is improved.

Further, the plurality of light barriers 120 may include a first light barrier and a second light barrier, the first light barrier is located between the second light barrier and the light source assembly 200, the first light barrier has a first light exit hole, the second light barrier has a second light exit hole, and a projection of the second light exit hole may be located within a projection of the first light exit hole in a direction perpendicular to the first light barrier.
