The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model will be further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 1, an audience lamp comprises a hollow light-emitting cavity composed of a side plate 30, an end cover 40, a top plate 50 and a bottom plate 60, wherein a light-emitting assembly 10 is arranged on the top plate 50; the light emitting assembly 10 includes a light source 11 located inside the light emitting cavity, and visible light emitted by the light source 11 penetrates through the top plate 50 and then is emitted to the outside of the hollow cavity;

the light source 11 is sequentially provided with a heat dissipation block 15 and a heat dissipation fan 16 in a direction towards the bottom plate 60, and a heat dissipation airflow of the heat dissipation fan 16 flows along the bottom plate 60 in a direction towards the top plate 50;

the bottom plate 60 is provided with a bottom plate air inlet 61 at a position close to the heat dissipation fan 16, the top plate 50 is provided with a top plate air outlet 51 at a position close to the heat dissipation fan 16, and the side plate 30 is provided with a side air gap 33 at a position close to the heat dissipation fan 16.

In this embodiment, the heat generated by the light source 11 is conducted to the heat radiation block 15, and then the heat radiation air flow generated by the heat radiation fan 16 is sequentially sucked from the bottom plate air intake holes 61 → passed through the heat radiation block 15 → discharged from the top plate air discharge holes 51, so that the heat of the light source 11 is rapidly radiated by the highly efficient heat radiation air flow.

Further, the outside of the light source 11 is provided with a reflector 12 closely attached to the light source 11, the light-emitting direction of the reflector 12 is provided with a lens 14, and the reflector 12, the lens 14 and the light source 11 form a closed light source cavity.

In this embodiment, the light source cavity reaches the dustproof level of IP5x, the light emitting point of the light source 11 is located in the light source cavity, and the light emitted from the light emitting point is emitted after being dimmed by the reflector 12 and the lens 14; due to the adoption of open heat dissipation, the light source cavity reaches the dustproof grade of IP5x, so that external dust can be prevented from entering the light source cavity, and the light emitting efficiency and the emission efficiency are prevented from being influenced.

Further, two or more light emitting assemblies 10 are disposed on the top plate 50.

Further, the side plate 30 comprises a lower side plate 31 and an upper side plate 32 which are formed by aluminum extrusion, the lower side plate 31 and the upper side plate 32 are respectively connected with the end cover 40, and a side air gap 33 is arranged between the lower side plate 31 and the upper side plate 32.

In the embodiment, the aluminum extrusion molding has good manufacturability, and the aluminum material has good heat-conducting property and is beneficial to heat dissipation; in addition, the lower side plate 31 and the upper side plate 32 with proper lengths can be flexibly cut according to the number of the light emitting assemblies 10 by adopting the extrusion molding, and the method has good adaptability and economy.

Further, a controller 20 connected with the bottom plate 60 is disposed inside the light emitting cavity, and electrical elements and electrical contacts of the controller 20 are coated with conformal coating.

The three-proofing paint is a paint with a special formula and is used for protecting a circuit board and related equipment from being corroded by the environment. The three-proofing paint has good high and low temperature resistance; after being cured, the coating becomes a layer of transparent protective film which has excellent insulating, damp-proof, anti-creeping, shockproof, dustproof, anti-corrosion, anti-aging, corona-resistant and other performances.

Because the open type heat dissipation is adopted, the electrical components and the electrical contacts (welding points, pressure contacts and the like) are inevitably influenced by dust and moisture in the operation process of the controller 20, so that the stability of the controller 20 is deteriorated, and the electrical components and the electrical contacts are coated with the three-proofing paint, so that the influences of dust, moisture and other environments can be avoided, and the stability is improved.

Further, the light source 11 is an LED light source, and a temperature sensor 18 is disposed at a position of the heat dissipation block 15 close to the light source 11.

The LED may generate high temperature during operation, and the LED lifetime may be reduced or failed due to the high temperature, and the temperature of the LED is obtained by the temperature sensor 18, so that the appropriate temperature control is performed.

Further, a T-shaped groove 34 is formed in the lower side plate 31.

In this embodiment, the T-shaped groove 34 is connected with the external bracket, so that the external bracket can be conveniently moved and fixed.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the protective scope of the present patent claims.
