Description

LED panel lamp

Technical Field

The utility model belongs to film and television outer shoot and studio panel light, more specifically say, relate to a waterproof LED panel light.

Background

The LED flat lamp is more and more widely used, but under rainy day or humid weather application environment, cause dull and stereotyped lamp interface or structure clearance department to intake easily to lead to electronic components to become invalid, so more and more users need the dull and stereotyped lamp of LED to have waterproof function, in order to satisfy user's demand, in the industry attach importance to the design of LED lamps and lanterns waterproof performance more and more. Especially because a large number of general external interfaces such as power input ports, DMX (digital multiplex) control input and output ports, etc. are often used on flat panel lamps. The price of the interface with the waterproof function and the price of the interface without the waterproof function are different by tens of times. If the interface with waterproof function is adopted, the price of the whole LED lamp can be greatly increased, so that how to realize a better waterproof effect with lower cost is a problem which is always solved by the industry.

If the publication date is 2018, 10, and 2, and the publication number is CN108613044A, the chinese patent with the patent name of a waterproof and dustproof LED flat lamp discloses a technical scheme of a waterproof LED lamp, in the technical scheme, the length and the width of a top plate are more than those of a frame by 6 cm, so that water dripping on the top plate can be prevented from flowing into the frame along the trend, and the waterproofness is improved.

If the announcement date is 2018, 3, 27 and the announcement number is CN207146125U, the Chinese patent with the patent name of the waterproof LED flat lamp also discloses a technical scheme of the waterproof LED lamp, the technical scheme is characterized in that a diffusion plate is bonded on a bottom plate of a frame by inserting connecting angle codes of frame sectional materials into transverse grooves of inverted T-shaped slots, a light guide plate and foam are sequentially placed on the diffusion plate, LED lamp strips are respectively arranged on two opposite sides of the light guide plate and bonded with the side walls of the frame, and four sides of the back plate are connected with vertical groove inserting buckles of the inverted T-shaped slots. Because the diffusion plate is adhered to the bottom plate of the bezel, water is prevented from being splashed into the flat lamp from the front side of the diffusion plate.

Different from above-mentioned two kinds of schemes, the utility model discloses provide a different technical scheme in addition and solve the waterproof problem of the dull and stereotyped lamp of LED.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1, fig. 2, fig. 5 and fig. 6, the utility model discloses a frame 1, frame connecting piece 2, light guide plate 3, light guide plate sealing washer 8, battery buckle 4, layering 9, back lid sealing washer 11, back lid 6, automatically controlled box 5, automatically controlled box sealing washer 14 and lamp plate 22, wherein, light guide plate 3 is installed on frame holding surface 10, is provided with light guide plate sealing washer 8 between light guide plate 3 and frame holding surface 10. The lamp panel 22 is installed between the side wall of the light guide plate 3 and the side wall of the frame 1, and is pressed by the pressing strip 9. The pressing strips 9 press the light guide plate 3 at the same time to press the light guide plate seal ring 8 tightly. The rear cover 6 is arranged on the frame 1, a rear cover sealing ring 11 is arranged between the rear cover 6 and the frame 1, and the rear cover 6 is provided with a battery buckle plate 4 and an electric control box 5. The utility model discloses an utilize the light guide plate sealing washer 8, back lid sealing washer 11, layering 9, light guide plate 3 and the back lid 6 between compress tightly each other the relation reach the sealing of major structure, thereby realize the utility model discloses good water-proof effects.

As shown in fig. 3, four rims 1 are connected by four rim connectors 2. Sealing glue is coated on the frame installation part 7 of the frame 1 or a sealing gasket is used, then the frame installation part 7 is installed on the frame connecting piece 2, and the sealing between the frames is realized by using the sealing glue or the sealing gasket, as shown in fig. 4.

As shown in fig. 7, be equipped with on the back lid 6 and be used for connecting battery buckle 4 with the utility model discloses an internal circuit's buckle trompil 12, buckle trompil 12's hole is along being provided with trompil boss 13, and trompil boss 13 sets up between battery buckle 4 and back lid 6. Thereby can be blockked by trompil boss 13 and can't get into along buckle trompil 12 when the rainwater passes through the region between battery buckle 4 and the back lid 6 along the edge of battery buckle 4 the utility model discloses inside, realize waterproof function.

As shown in fig. 6, a sealing ring 14 of the electronic control box is arranged between the electronic control box 5 and the rear cover 6. As shown in fig. 8 and 9, a groove 15 is provided on the electronic control box 5, the groove 15 can accommodate a corresponding external interface 17, the external interface 17 includes a power input interface, a DMX control input interface, and other types of general interfaces, and the number of the grooves 15 is the same as that of the external interfaces 17 to achieve matching between the two. In this embodiment, 3 external interfaces are taken as an example. The bottom of the recess 15 is provided with a recess opening for the passage of the pin of the external interface 17, which may be designed as a continuous recess opening 23 or a discontinuous recess opening 24 in particular embodiments. A groove sealing gasket 16 is arranged between the external interface 17 and the groove 15, and an opening for allowing the pin of the external interface 17 to pass through is arranged on the groove sealing gasket 16 corresponding to the pin of the external interface 17. In use, the external interface 17 is mounted on the electrical control box 5 and compressed against the groove gasket 16. For a common external interface 17 without waterproof function, when rainwater infiltrates from the mounting contact surface of the external interface 17 and the electrical control box 5 or infiltrates from the pin of the external interface 17, the groove 15 and the groove gasket 16 can play a role of blocking rainwater from entering the interior of the electrical control box 5.

As shown in fig. 8, the electrical control box 5 is provided with a rotary encoder hole 18 for mounting a rotary encoder 21. As shown in FIG. 10, the hole edge of rotary encoder hole 18 is provided with rotary encoder boss 19, the inner diameter of rotary encoder 21 is larger than the outer diameter of rotary encoder boss 19, and the distance between the bottom of rotary encoder 21 and surface 20 of electrical control box is smaller than the height of rotary encoder boss 19. Since the inner diameter of the rotary encoder 21 is larger than the outer diameter of the rotary encoder boss 19, rainwater cannot enter the electric control box from the surface of the rotary encoder 21. If the water flow is large, when the water enters from the gap between the rotary encoder 21 and the surface 20 of the electric control box, the water is blocked because the height of the rotary encoder boss 19 is larger than the distance between the bottom of the rotary encoder 21 and the surface 20 of the electric control box, so that the water cannot enter the electric control box 5 along the rotary encoder hole 18, and a good waterproof effect is realized.

The invention and its embodiments have been described above schematically, without limitation, in other specific forms without departing from the spirit or essential characteristics thereof. The embodiment shown in the drawings is only one embodiment of the invention, the actual structure is not limited thereto, and any reference signs in the claims shall not limit the claims concerned. Therefore, if a person skilled in the art receives the teachings of the present invention, without inventive design, a similar structure and an embodiment to the above technical solution should be covered by the protection scope of the present patent.
