Description

Thermoelectric separated LED array light source

Technical field

This utility model is related to a kind of LED light source, particularly a kind of thermoelectric separated LED array light source.

Background technology

LED array light source is conventional light sources in LED lamp, and at present, LED array light source generally includes substrate and some Paster LED chip, substrate arranges circuit, and paster LED chip is directly mounted on circuit, forms LED circuit, LED chip At least need to conduct heat on substrate through patch support and this two-layer thermoresistance layer aspect of circuit layer, radiating efficiency is low, shadow Ring the service life of LED chip.

Content of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of thermoelectric separated LED array light source.

This utility model solves its technical problem and be employed technical scheme comprise that：

Thermoelectric separated LED array light source, including the dot matrix module of at least one, described dot matrix module includes a thermoelectricity and divides On the substrate of formula, described substrate, array is provided with some grooves, and bottom portion of groove has thermal conductive surface, is configured with described groove LED unit, has one or more LED chips in each LED unit, described substrate upper surface is provided with each LED of connection The LED circuit of unit.

At least two LED unit is in parallel to form light sources in parallel, with power supply circuits after adjacent light sources series connection in parallel Connect, form the circuit structure of series connection after first parallel connection.

Described groove is circular groove.

Described substrate is made up of aluminum or copper material.

Including at least two dot matrix module, adjacent dot matrix module is connected in series.

One or more LED chips is encapsulated in groove by packing colloid, is configured with fluorescence in described packing colloid Bisque.

The beneficial effects of the utility model are：Thermoelectric separated LED array light source, including the dot matrix module of at least one, Described dot matrix module includes the substrate of a thermoelectric separated, and on described substrate, array is provided with some grooves, joins in described groove It is equipped with LED unit, there are in each LED unit one or more LED chips, described substrate upper surface is provided with and connects each The LED circuit of LED unit, in this utility model, bottom portion of groove has thermal conductive surface, LED chip be directly encapsulated on groove with Thermal conductive surface contacts, and is then electrically connected with by the LED circuit of substrate upper surface, forms thermoelectricity isolating construction, and its radiating is than general Lead to SMD dot matrix and lacked two-layer thermal resistance, improve radiating efficiency, reduce the operating temperature of chip, chip service life increases, And one or more LED chips is encapsulated in same groove so as to chip fully exciting to fluorescent material, increase luminous effect Rate.

Brief description

With reference to the accompanying drawings and examples this utility model is further illustrated.

Fig. 1 is the front schematic view of this utility model substrate；

Fig. 2 is this utility model circuit theory schematic diagram.

Specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 are the structural representations of one specific embodiment of this utility model, as illustrated, hot Electric separation type LED array light source, including the dot matrix module 1 of at least one, described dot matrix module 1 includes the base of a thermoelectric separated Plate 2, on described substrate 2, array is provided with some grooves 21, and groove 21 bottom has thermal conductive surface, is configured with described groove 21 LED unit, is packaged with one or more LED chips by packing colloid in each LED unit, is configured with glimmering in packing colloid Light powder, forms phosphor powder layer, and described substrate 2 upper surface is provided with the LED circuit connecting each LED unit, in this utility model In, groove 21 bottom has thermal conductive surface, and LED chip is directly encapsulated into and is contacted with thermal conductive surface on groove 21, and heat is direct Conduct to substrate 2, be then electrically connected with by the LED circuit of substrate upper surface, form thermoelectricity isolating construction, its radiating is than common SMD dot matrix has lacked two-layer thermal resistance, improves radiating efficiency, reduces the operating temperature of chip, and chip service life increases, and One or more LED chips is encapsulated in same groove so as to chip fully exciting to fluorescent material, increase luminous efficiency.

Preferably, in this utility model, adopt circuit structure in parallel after first connecting, as shown in Fig. 2 at least two LED unit is in parallel to form light sources in parallel, is connected with power supply circuits, goes here and there after forming first parallel connection after adjacent light sources series connection in parallel The circuit structure of connection, reducing operating current difference between lamp bead so as to light uniformly, even if breaking down a chip, also will not make Large area is become not work.

Preferably, in the present embodiment, described groove 21 is circular groove, certainly, in specific implementation process, also can adopt With the groove of other shapes, such as square, oval etc., it is not described in detail here.

In this utility model, described substrate 2 is the heat-conducting substrate being made up of Heat Conduction Materials such as aluminum or copper materials.

In specific implementation process, multiple dot matrix modules 1 can form LED array light source in modes such as logical series, parallel, Form the light sources of different capacity, to meet different use demands.

Above preferable enforcement of the present utility model is illustrated, certainly, this utility model can also using with The different form of above-mentioned embodiment, those of ordinary skill in the art without prejudice to the present invention spirit on the premise of made etc. Same conversion or corresponding change, all should belong in protection domain of the present utility model.
