Abstract

The utility model relates to the LED field, in particular to a waterproof LED module. The waterproof LED module comprises a substrate, a group of LED light beads, a lead-out wire and a heat-conducting encapsulation adhesive layer, wherein the LED light beads are welded on the substrate; the lead-out wire is leaded out from the group of LED light beads; and the heat-conducting encapsulation adhesive layer is encapsulated on the substrate, and seals both the solder spot of the group of LED light beads and the solder spot of the lead-out wire. Compared with the prior art, the utility model ensures that the conductive parts of the solder spot of the LED light beads and the solder spot of the lead-out wire are sealed by encapsulating a layer of heat-conducting encapsulating adhesive layer on the substrate so that the waterproof LED module has the waterproof effect. The waterproof LED module can be directly applied to the LED lamps without the sealing elements such as glass, transparent plastic, and the like, thereby improving the luminance of the LED lamp.

Description

A kind of Waterproof LED module

Technical field

The utility model relates to the LED field, is meant a kind of Waterproof LED module especially.

Background technology

Continuous development along with the LED technology, the range of application of LED more and more widely, the LED light fixture, extensive uses such as LED curtain wall, existing LED light fixture, it much is to adopt the LED module to constitute that the LED curtain wall has, the LED module generally includes installation base plate, LED lamp pearl and cover plate, because LED module of the prior art is non-watertight, therefore forming the LED light fixture by the LED module, just need be provided with waterproof glass during the LED curtain wall in the outside of light fixture, water-tight mechanisms such as waterproof transparent plastic, just there is following shortcoming in this: one, because glass, light transmittances such as transparent plastic at most also just can only reach about 90%, so can reduce the brightness of LED; Two, be unfavorable for the LED heat radiation.

The utility model content

Main purpose of the present utility model is to overcome that the LED module does not have the shortcoming of waterproof action in the prior art, and a kind of Waterproof LED module is provided.

The utility model adopts following technical scheme:

A kind of Waterproof LED module comprises

One substrate;

One assembly welding is connected to the LED lamp pearl on this substrate;

One draws lead from what this group LED lamp pearl was drawn;

One heat conduction embedding glue-line, embedding all seal the Tibetan with the solder joint of this group LED lamp pearl and this solder joint of drawing lead on this substrate.

According to a better embodiment of the present utility model, also comprise a cover plate, the corresponding accommodation hole that is provided with a group corresponding to described LED lamp pearl on this cover plate, this cover plate are covered on outside the described heat conduction embedding glue-line and by locking part and described substrate and fix.

According to a better embodiment of the present utility model, around the described heat conduction embedding glue-line and leave one between the described substrate and allow bit space, convex to form one around the described cover plate lower surface and allow the suitable leg of bit space with this.

According to a better embodiment of the present utility model, described leg is provided with and supplies the described perforation that lead passes through of drawing.

According to a better embodiment of the present utility model, the accommodation hole on the described cover plate is outwards open horn-like.

According to a better embodiment of the present utility model, the thickness of described LED lamp pearl is greater than the thickness of described heat conduction embedding glue-line.

According to a better embodiment of the present utility model, the thickness of described LED lamp pearl is greater than the thickness sum of the thickness and the described cover plate of described heat conduction embedding glue-line.

By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of LED waterproof module of the present utility model has following advantage:

One, the utility model is by embedding one deck heat conduction embedding glue-line on substrate, the solder joint of LED lamp pearl is all sealed the Tibetan protection with the current-carrying parts such as solder joint of drawing lead, make Waterproof LED module of the present utility model have waterproof effect, can directly apply to the LED light fixture, light fixture need not to be covered with seals such as glass, transparent plastic outward, can improve the brightness of LED light fixture, compare with the light fixture that is covered with seals such as glass, transparent plastic, under the situation of equal brightness, can save energy more than 10%, the environmental protection concept that composite energy-saving reduces discharging should vigorously promote the use;

Two, the design of product modularity is used as light fixture after the parallel connection of a plurality of Waterproof LED module of the present utility model, and partial L ED module is convenient for changing, keeps in repair after damaging;

Three, because Waterproof LED module of the present utility model is applied to need not to be covered with seals such as glass, transparent plastic behind the light fixture, the LED module is directly exposed to the light fixture outside, is beneficial to the LED heat radiation;

Four, Waterproof LED module of the present utility model is elegant in appearance, and the vestige of all solder joints all be cannot see behind the embedding heat conduction embedding glue-line;

Five, adopt the LED light fixture of Waterproof LED module of the present utility model owing to saved seals such as glass, transparent plastic, overall structure is comparatively brief, meets the advanced design theory of optimal design;

Six, around the heat conduction embedding glue-line and leave one between the substrate and allow bit space, convex to form one around the cover plate lower surface and allow the suitable leg of bit space with this, to allow bit space fill just at cover plate and the fixing back of substrate leg, make Waterproof LED module compact overall structure of the present utility model, attractive in appearance, it is firm to connect;

Seven, the accommodation hole on the cover plate is outwards open horn-like, is convenient to distributing of LED lamp pearly-lustre;

Eight, the thickness of LED lamp pearl is convenient to distributing of LED lamp pearly-lustre greater than the thickness of heat conduction embedding glue-line.
