Description

LED down lamp with good heat dissipation effect

Technical Field

The utility model relates to a LED down lamp that radiating effect is good belongs to commercial lighting technology field.

Background

The LED down lamp is a lighting lamp embedded into a ceiling and emitting light downward, and has the biggest characteristic that the whole unity and perfection of architectural decoration can be kept, a light source is utilized to hide the interior of the architectural decoration, the LED light source is not exposed, at present, the power supply power of the traditional LED commercial lighting down lamp is low, most of the traditional LED commercial lighting down lamp is NO-IC type lamps, the heat dissipation effect is poor, and the traditional LED commercial lighting down lamp is not allowed to be covered by heat insulation cotton when in use.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome among the prior art LED down lamp radiating effect poor, can not be by the defect that thermal-insulated cotton covered, provide a LED down lamp that the radiating effect is good, solve the heat dissipation problem through installing metal casing additional.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a LED down lamp that radiating effect is good, includes down lamp body and metal casing, and the metal casing passes through the locking screw fastening at the top of down lamp body, and the plastic power shell contact of metal casing bottom and down lamp body, the top of metal casing is provided with the metal flip that can open. Preferably, the locking screw is an M4 machine thread screw. Can guarantee that metal casing is effectual to contact with the plastic power shell, play good radiating effect, ensure that the temperature of down lamp during operation power is no longer than 90 ℃. Preferably, the metal shell is made of SECC material with good heat dissipation.

Be provided with the bump on the metal flip, metal flip carries out unsmooth cooperation through bump and metal casing to can open metal flip when needing, do not influence and adjust colour temperature and power through dial switch on the down lamp body.

Furthermore, a flanging is arranged on the metal flip cover. Preferably, the number of the turned edges is two, the turned edges are uniformly distributed on two sides of the salient points, and the turned cover can be prevented from shaking left and right after being tightly closed.

Furthermore, the splicing part of the metal shell is of a built-in self-riveting structure. The self-riveting structure comprises a counter bore and a thread-drawing hole. During splicing, two ends to be spliced are attached together, then the die punch head enables the thread drawing hole to expand and fill into the corner hole of the counter bore, so that the thread drawing hole and the corner hole are assembled together, and the whole appearance is attractive and integrated.

The utility model discloses the beneficial effect who reaches is: the utility model discloses an increase metal casing and strengthen the heat dissipation of whole lamp on the power, make whole lamp can use under high-power, satisfy different customers' user demand, whole lamp looks pleasing to the eye an organic whole.

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 presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Examples

The utility model provides a 9.5 inches radiating effect good LED down lamp through adding metal casing solution heat dissipation problem, includes down lamp body 4 and metal casing 3, and metal casing 3 fastens at the top of down lamp body 4 through M4 machine tooth screw 1, and the plastic power shell contact of metal casing 3 bottom and down lamp body 4, the top of metal casing 3 is provided with the metal flip 2 that can open. The metal casing adopts the better SECC material of heat dissipation, and the effectual and plastic power shell contact of metal casing plays good radiating effect, ensures that the temperature of down lamp during operation power is no longer than 90 ℃.

Be provided with the bump on metal flip 2, metal flip 2 carries out unsmooth cooperation through bump and metal casing 3 to can open metal flip when needing, do not influence and adjust colour temperature and power through dial switch on the down lamp body. The metal flip cover 2 is provided with two flanges 5 which are uniformly distributed on two sides of the salient point, so that the metal flip cover 2 can be prevented from shaking left and right after being tightly closed.

The splicing position of the metal shell is provided with an internal self-riveting structure 6. The self-riveting structure comprises a counter bore and a tapping hole. During splicing, two ends to be spliced are attached together, then the die punch head enables the thread drawing hole to expand and fill into the corner hole of the counter bore, so that the thread drawing hole and the corner hole are assembled together, and the whole appearance is attractive and integrated.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
