Description

Dustproof and dampproofing LED down lamp

Technical Field

The invention relates to an LED down lamp, in particular to a dustproof and moistureproof LED down lamp.

Background

The projector lamps are used in some exhibition halls, stages, and show cases of department stores to provide lighting and lighting effects. Because the LED light source has better brightness and long service life, the LED light source is gradually applied to the projection lamp. When the LED emits light, heat is difficult to diffuse in due time, the LED light source is easy to damage due to poor heat dissipation effect, and the service life of the projection lamp is shortened. After the existing LED projection lamp is used for a long time, dust easily enters a radiator in the lamp body from an air inlet, and the radiating effect is reduced. In addition, therefore, there is a need for improvements in the prior art to avoid the disadvantages of the prior art.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a dustproof and moistureproof LED down lamp.

The invention is realized by the following technical scheme:

dustproof dampproofing LED down lamp, including the lamp body and with lamp body swing joint's linkage, the lamp body includes the cavity casing and installs LED light-emitting component, radiator, fan, controller and the drive power supply in the cavity casing in proper order, the cavity casing is equipped with the fender dirt subassembly, the fender dirt subassembly comprises the baffle at least.

The driving power supply is respectively electrically connected with the LED light-emitting assembly, the fan and the controller, an air inlet groove and an air exhaust groove are circumferentially distributed on the outer side wall of the hollow shell, the air inlet groove is arranged at a position matched with the air inlet end of the fan, the air exhaust groove is arranged at a position matched with the radiator, and the baffle plate obliquely and upwards extends to be arranged on the inner wall of the air inlet port of the air inlet groove.

The hanging device comprises a U-shaped support, a hook and a rotating connecting rod for connecting the U-shaped support and the hook, and two open ends of the U-shaped support are respectively connected with the lamp body in a rotating mode through screws.

The invention has the beneficial effects that: the invention prevents partial dust from directly entering the lamp body from the outside through the baffle plate, prevents a large amount of dust from attaching to the short-term inner surface of the radiator, and prolongs the service life of the lamp body.

Drawings

The invention is further described below with reference to the accompanying drawings:

FIG. 1 is an exploded view of the present invention;

in the figure: 1. the LED lamp comprises a hollow shell, 2 LED light-emitting components, 3 a radiator, 4 a fan, 5 a controller, 6 an air inlet groove, 7 an exhaust groove, 8 a U-shaped support, 9 a hook and 10 a rotating connecting rod.

Detailed Description

As shown in fig. 1, dustproof and moistureproof LED down lamp comprises a lamp body and a suspension device movably connected with the lamp body, wherein the lamp body comprises a hollow shell 1, and an LED light-emitting assembly 2, a radiator 3, a fan 4, a controller 5 and a driving power supply which are sequentially arranged in the hollow shell 1, the hollow shell 1 is provided with a dust-blocking assembly, and the dust-blocking assembly at least comprises a baffle. Can avoid part dust directly to get into in the lamp body from the outside through the baffle, prevent that radiator 3 short-term internal surface from attaching a large amount of dust, improve lamp body life. The controller 5 can control the LED light-emitting component 2 to realize various light-emitting effects, and is suitable for various use environments.

The driving power supply is respectively electrically connected with the LED light-emitting component 2, the fan 4 and the controller 5, an air inlet groove 6 and an air exhaust groove 7 are circumferentially distributed on the outer side wall of the hollow shell 1, the setting position of the air inlet groove 6 is matched with the air inlet end of the fan 4, the setting position of the air exhaust groove 7 is matched with the setting position of the radiator 3, and the baffle plate slantly and upwards extends to be arranged on the inner wall of an air inlet port of the air inlet groove 6. Can avoid part dust directly to get into in the lamp body from the outside through the baffle, prevent that radiator 3 short-term internal surface from attaching a large amount of dust, improve lamp body life. The controller 5 can control the LED light-emitting component 2 to realize various light-emitting effects, and is suitable for various use environments.

In order to improve the installation convenience, the suspension device comprises a U-shaped support 8, a hook 9 and a rotating connecting rod 10 for connecting the U-shaped support 8 and the hook 9, and two open ends of the U-shaped support 8 are respectively connected with the lamp body in a rotating mode through screws.

Certainly, the lateral wall of cavity casing 1 can be equipped with two pairs of mounting holes, can adopt the plastics head screw rod, can change a pair of mounting holes of using as required during the use, prevents that the mounting hole from skidding and influence the result of use.
