Abstract

The utility model relates to an LED light source module, in particular to an LED light source module of a direct insert type metal base plate, comprising a clamp housing, a lampshade, a direct insert type LED and a metal-based circuit board, wherein an accommodating space is formed between the lamp housing and the lampshade; the direct insert type LED and the metal-based circuit board are arranged in the accommodating space; the metal-based circuit board is arranged at the backside of the LED; the size of the edge of the metal-based circuit board is smaller than or equal to the internal diameter of the lamp housing; the lamp housing is provided with a metal-based circuit board jointing part; and the metal-based circuit board is jointed with the metal-based circuit board jointing part. When the LED light source module of the direct insert type metal base plate is installed, the metal base plate is jointed with the lamp housing; and in the use process, after absorbing the heat radiated by the LED, the metal base plate can rapidly transfer the heat to the lamp housing for radiating heat, thereby realizing fine heat radiating effect.

Description

Direct plugging-in metal substrate led light source module

Technical field

The utility model relates to a kind of led light source module, especially a kind of led light source module of direct plugging-in LED metal substrate.

Background technology

At present, direct plugging-in led light source module is with its low-power consumption, luminous efficiently and obtained use more and more widely, used widely now as family expenses and other fields such as LED fluorescent tube, LED street lamps, but because the caloric value of led light source module directly influences its service life, so the heat radiation of led light source module becomes the important means that improves the led light source module life-span.

Existing direct plugging-in led light source module generally comprises lamp housing and lampshade and the led light source module between lamp housing and lampshade, the common circuit board of existing direct plugging-in led light source module is the glass plate, and glass plate heat radiation is very undesirable, institute so that its thermal diffusivity have a greatly reduced quality.

Summary of the invention

The purpose of this utility model provides a kind of direct plugging-in LED metal substrate led light source module with better heat radiating effect.

To achieve these goals, the utility model adopts following technical scheme:

It comprises lamp housing, lampshade, direct plugging-in LED and metal-base circuit plate, form a spatial accommodation between lamp housing and the lampshade, direct plugging-in LED and metal-base circuit plate are located in the described spatial accommodation, described metal-base circuit plate is located at the back side of LED, its improvement is, described LED metal-base circuit panel edges size is less than or equal to the lamp housing internal diameter, and described lamp housing is provided with the metal substrate sticking part, and described metal substrate and described sticking part fit.

Preferably, described metal substrate is provided with perforation, is provided with insulating materials in the described perforation.

Preferably, described lamp housing is the metal material lamp housing.

Preferably, described metal substrate closely links to each other with the metal material lamp housing,

Preferably, described lamp housing outside is provided with heat sink strip.

The led light source module of direct plugging-in LED metal substrate of the present utility model metal substrate and lamp housing when mounted fits, in use, after the heat that metal-base circuit plate absorption LED sends, can be passed to rapidly and carry out distributing of heat on the lamp housing, thereby realize better heat radiating effect.

Description of drawings

Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.

The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.

The specific embodiment

As shown in Figure 1, embodiment of the present utility model comprises that it comprises lamp housing 1, lampshade 2, direct plugging-in LED 3 and metal-base circuit plate 4, form a spatial accommodation 5 between lamp housing 1 and the lampshade 2, direct plugging-in LED 3 and metal-base circuit plate 4 are located in the described spatial accommodation 5, described metal-base circuit plate 4 is located at the back side of LED 3, described metal-base circuit plate 4 edge sizes are less than or equal to lamp housing 1 internal diameter, the two edges of described lamp housing 1 are provided with metal substrate sticking part 11, and described metal substrate 4 fits with described sticking part 11.

In use, after the heat that metal-base circuit plate absorption LED sends, can be passed to rapidly and carry out distributing of heat on the lamp housing, thereby realize better heat radiating effect.

Because direct plugging-in led light source module need insert led light source on the metal-base circuit plate,, be provided with insulation material layer 411 in the described perforation 41 so the described metal substrate 4 of present embodiment is provided with perforation 41.

In order to be that lamp housing can dispel the heat more rapidly, the described lamp housing 1 of present embodiment is the metal material lamp housing.

In order further to promote radiating effect, described lamp housing 1 outside is provided with heat sink strip 12, and described heat sink strip 12 has increased lamp housing surface and extraneous contact area, has realized better radiating effect.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
