Technical Field

The invention relates to the technical field of lighting, in particular to a lamp holder with good heat dissipation performance.

Background

Along with the development of electronic technology, LED lamps develop along with it, and as is well known, LED lamps have higher requirements for heat dissipation in the use process, and because the service environment of LED lamps, especially outdoor environment, has more uncertain factors, the heat dissipation of LED lamps is hindered, for example, the existing LED lamps need heat dissipation holes for heat dissipation, and the heat dissipation holes are easy to be filled with water to damage circuit structures in rainy days.

Disclosure of Invention

The invention aims to provide a lamp cap with good heat dissipation performance, and solves the problems.

The technical scheme of the invention is as follows: a lamp holder with good heat dissipation performance comprises a rear lamp cover, an LED lamp panel fixed in the rear lamp cover and a front lamp cover detachably connected with the rear lamp cover, wherein the inner rear lamp cover is divided into a light emitting area and a backlight area by the LED lamp panel; a plurality of corrugated sheets are circumferentially arranged on the inner surface of the rear lampshade by taking the DED lamp panel as a center, a groove-shaped structure is formed between every two adjacent corrugated sheets, and the corrugated sheets penetrate through the light emitting area and the backlight area; the rear end of the rear lamp shade is provided with a plug, and the plug is detachably connected with the rear lamp shade; a hole communicated with the backlight area is formed in the plug; under the condition that the plug is connected with the rear lamp shade in place, the hole is blocked by the rear lamp shade; and under the condition that the plug is not connected with the rear lamp shade in place, the hole is communicated with the outside.

Preferably, the plug is in threaded connection with the rear lamp shade.

Preferably, the position where the rear lamp cover is connected with the plug is provided with an internal thread, and the position where the plug is connected with the rear lamp cover is provided with an external thread matched with the internal thread.

Preferably, the plug is provided with a fixing portion for fixing the lamp cap to the carrier, and the fixing portion is provided with a fixing structure.

Preferably, the fixing structure is a fixing hole.

When the lamp holder with good heat dissipation performance is used, heat generated when the lamp beads in the light emitting areas emit light can be dissipated at the following positions:

1. heat dissipation through stupefied piece: the heat is directly transferred to the lampshade through the corrugated sheet to dissipate heat;

2. heat dissipation through air: the heat of luminous zone can dispel the heat through flute profile structure and stupefied piece and the air in the back light zone, and under general condition, the end cap can be unscrewed and make the hole communicate with each other with the external world thereby reach the purpose with external quick heat exchange, can screw down the end cap temporarily and hide the hole in back lamp shade inboard when having rain, reaches rainproof purpose.

In conclusion, the lamp holder with good heat dissipation performance has a good heat dissipation effect.

Fig. 1 is a schematic structural diagram of a lamp holder with good heat dissipation performance in an embodiment of the invention.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1, the invention provides a lamp holder with good heat dissipation performance, which comprises a rear lamp shade 1, an LED lamp panel 2 fixed in the rear lamp shade, and a front lamp shade 3 detachably connected with the rear lamp shade, wherein the inner rear lamp shade is divided into a light emitting area 4 and a backlight area 5 by the LED lamp panel; a plurality of corrugated sheets 6 are circumferentially arranged on the inner surface of the rear lampshade by taking the DED lamp panel as a center, a groove-shaped structure is formed between every two adjacent corrugated sheets, and the corrugated sheets penetrate through the light emitting area and the backlight area; a plug 7 is arranged at the rear end of the rear lamp shade, and the plug is detachably connected with the rear lamp shade; a hole 8 communicated with the backlight area is formed in the plug; under the condition that the plug is connected with the rear lamp shade in place, the hole is blocked by the rear lamp shade; and under the condition that the plug is not connected with the rear lamp shade in place, the hole is communicated with the outside. The plug is connected with the rear lamp cover through a preferable thread, specifically, an internal thread is arranged at the position where the rear lamp cover is connected with the plug, and an external thread matched with the internal thread is arranged at the position where the plug is connected with the rear lamp cover.

In order to fix the lamp cap, a fixing portion 9 used for fixing the lamp cap on the carrier is arranged on the plug, and a fixing structure is arranged on the fixing portion. Wherein the fixing structure is preferably a fixing hole 10.

When the lamp holder with good heat dissipation performance is used, heat generated when the lamp beads in the light emitting areas emit light can be dissipated at the following positions:

1. heat dissipation through stupefied piece: the heat is directly transferred to the lampshade through the corrugated sheet to dissipate heat;

2. heat dissipation through air: the heat of luminous zone can dispel the heat through flute profile structure and stupefied piece and the air in the back light zone, and under general condition, the end cap can be unscrewed and make the hole communicate with each other with the external world thereby reach the purpose with external quick heat exchange, can screw down the end cap temporarily and hide the hole in back lamp shade inboard when having rain, reaches rainproof purpose.

In conclusion, the lamp holder with good heat dissipation performance has a good heat dissipation effect.

It should be noted that the above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, and such changes and modifications should be covered by the protection scope of the invention.
