Abstract

The utility model relates to the technical field of LED, in particular to a novel LED heat radiating lamp strip, comprising a LED lamp strip and a strip outer frame, wherein the interior of the outer frame is provided with a box-shaped cavity; a step is respectively arranged at the included angle positions of the bottom and the two side walls of the box-shaped cavity; the LED lamp strip is arranged in the box-shaped cavity, and both edges of the LED lamp strip are erected on the step; and a layer of heat radiating silica gel is filled between the two steps under the LED lamp strip. The LED lamp strip is basically arranged in the outer frame and has large contact area with the outer frame. If the outer frame is made from material with high heat conducting and radiating coefficient, e.g. aluminum profiles, the heat radiating effect is ideal, and due to the mutual function of the heat radiating silica gel at the bottom of the LED lamp strip, the heat radiating property is good.

Description

A kind of New LED thermal louver bar

Technical field

The utility model relates to the LED technical field, is specifically related to a kind of New LED thermal louver bar.

Background technology

At present, because the scope of application of lamp bar screen strengthens, the frequency of Shi Yonging is very high out of doors, and the display effect of plug-in unit lamp is inferior to the paster lamp far away.Simultaneously, consider waterproof effect, so general lamp bar has all adopted 5050 paster lamps, the characteristics of 5050 paster lamps are the brightness height, and color is beautiful, soft, but that shortcoming is exactly a caloric value is big.

Secondly, existing LED lamp bar structure is directly the PCB circuit board to be placed on the step that protrudes, and several millimeters space is set below, by air in this space to lead heat radiation.After the LED lamp was lighted, the lamp bar can produce a large amount of heats, because the heat conductivility of air is not fine, can cause internal temperature too high.Thereby, often cause rosin joint, dead lamp, a series of problem such as too fast decays owing to temperature is too high.

The utility model content

In order to address the above problem, the purpose of this utility model is to provide the better New LED thermal louver of a kind of radiating effect bar.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of New LED thermal louver bar comprises a LED lamp bar, a bar shaped housing, is provided with a box-like cavity in the described housing, respectively is provided with a step in the bottom of described box-like cavity and the angle position of two side; Described LED lamp bar is installed in the box-like cavity, and the two edges of described LED lamp bar are erected on this step; Below described LED lamp bar, between described two steps, be filled with one deck thermal grease.

As further improvement of the utility model, frame bottom is provided with first counterbore outside described, on the described LED lamp bar, be positioned at first counterbore directly over locate to be provided with and keep away a hole; Between described housing and the LED lamp bar, by running through first counterbore with the screw that presses of keeping away a hole, lock together with the nut that is positioned at LED lamp bar upper surface;

As further improvement of the utility model, the double-screw bolt inside of the described screw that presses is provided with the interior tooth that cooperates with first screw; Be provided with a face shield above the box-like cavity of housing, described face shield upper surface is provided with second counterbore that first screw is installed; First screw by running through second counterbore, with the screw that presses on interior tooth between be threaded, housing, LED lamp bar and face shield are fixed together.

In the utility model, LED lamp bar is arranged in housing substantially, and is bigger with the housing contact area, leads the higher material of coefficient of heat transfer if housing adopts, as: aluminium section, then its radiating effect is just very good; Add the acting in conjunction of LED lamp bar bottom thermal grease, make that heat dispersion of the present utility model is better.
