Description

A kind of COB light module
Technical field
This utility model belongs to light emitting diode product encapsulation field, particularly relates to a kind of COB Light module.
Background technology
In LED application, LED module is because of its super brightness, low-power consumption, service life The features such as length, simple installation, are widely used in advertising lamp box, mark signboard, publicity instruction The places such as mark, along with the gradually maturation of LED module technology, its range of application will be more Extensively, in LED module, Chang Shiyong's is exactly COB encapsulation, but current COB encapsulating light emitting Efficiency is low, and lighting angle is big, and hot spot is obvious, radiating effect is poor;And little light-emitting area is high-power COB light source cost high, production efficiency is low.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide one COB light module, its light efficiency that can solve COB is not enough, fluorescent colloid due to temperature too high and Cause the problem that colloid ftractures.
The purpose of this utility model realizes by the following technical solutions:
A kind of COB light module, including LED chip, circuit substrate, silica gel fluorescence coating, encloses Dam, transparent silicon glue-line and pad, described circuit substrate has a slide glass district, described slide glass district are A groove on circuit substrate, described silica gel fluorescence coating is positioned at slide glass district, described transparent silicon glue-line position On silica gel fluorescence coating, described box dam is positioned at the periphery of transparent silicon glue-line;Described pad includes Positive terminal pad and negative terminal pad, described LED chip is arranged on slide glass district, described LED chip Positive pole is electrically connected with positive terminal pad by gold thread, and described LED chip negative pole passes through gold thread with negative Pole pad is electrically connected with.
Preferably, the height of described silica gel fluorescence coating is identical with slide glass district height.Can be further Solve the technical problem of the thickness of silica gel fluorescence coating.
Preferably, described box dam and transparent silicon glue-line is generally circular in shape.Can solve further to enclose The problem of the shape of dam and transparent silicon glue-line.
Preferably, described transparent silicon glue-line covers silica gel fluorescence coating.Silica gel can be solved further glimmering Photosphere and the size issue of transparent silicon glue-line.
Preferably, the projection on circuit substrate of the described transparent silicon glue-line and silica gel fluorescence coating are at electricity On base board, projection overlaps.The size that can solve silica gel fluorescence coating and transparent silicon glue-line further is asked Topic.
Compared to existing technology, the beneficial effects of the utility model are:
The COB light source of employing fluorescent material near field of the present utility model coating processes solves fluorescent material Heat radiation, it is to avoid colloid temperature overstep the extreme limit temperature cause colloid cracking problem;And this COB Light module can improve hot spot, reduces cost, improves production efficiency.Point on silica gel fluorescence coating Transparent silica gel realizes less beam angle and bigger central light strength, promotes the light of COB light module Effect.
Accompanying drawing explanation
