Description

A kind of high-power LED lighting fixture structure

Technical field

The utility model relates to field of illuminating lamps, relates in particular to the LED lighting.

Background technology

LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.Advantages such as it has that volume is little, power consumption is low, long service life, high brightness, low in calories, environmental protection, sturdy and durable, advanced technology.Therefore, be the development trend of following lighting source.

At present, the main packing forms of great power LED all mainly concentrates on specifications such as 1W/3W/5W, and is used for lighting of home or industrial lighting field, and the brightness in single lamp source also can't satisfy the demands.So the settling mode of industry is exactly the great power LED with many at present,, improve whole brightness, to meet the demands by series-parallel mode.But this kind application model relative cost is higher.If there is a LED to damage dead lamp, then can cause the LED in same loop not work, cause not working of some light-emitting zones.

The utility model content

Therefore, at the problems referred to above, propose a kind of encapsulation technology of polycrystalline great power LED module and, and propose a kind of high-power LED lighting fixture structure that can be applied to a series of illuminations such as bulb lamp, Down lamp in conjunction with LED substrate heat dissipation technology.

The utility model adopts following technical scheme:

A kind of high-power LED lighting fixture structure comprises:

One LED substrate which is provided with anodal and negative pole tie point;

A plurality of LED encapsulation units, comprise arranged in matrix in the LED of LED substrate wafer, electrically connect the gold thread of LED wafer and be packaged in the LED wafer and the LED substrate on silica gel;

One bulb shell comprises a connecting seat body, is arranged at and connects the fin radiator on the pedestal and be arranged at retainer ring on the fin radiator, the fixing above-mentioned LED substrate in described retainer ring upper end;

One lampshade, fastening is arranged on the retainer ring of above-mentioned bulb shell.

Further, described LED substrate is an aluminium base.

Perhaps, described LED substrate is a ceramic substrate.

The utility model adopts as above technical scheme, has the following advantages:

1, the Combination Design of LED module can effectively reduce disposable packaging cost;

2, the packing forms of Fen Saning helps lowering the heat dissipation design cost;

3, be convenient to optical design;

4, power supply design simplification;

5, cheap encapsulation architecture, packing forms is various.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult Fig. 1 to shown in Figure 6, high-power LED lighting fixture structure of the present utility model comprises:

One LED substrate 1 which is provided with anodal and negative pole tie point 101,102.Preferably, described LED substrate 1 is an aluminium base.Perhaps, described LED substrate 1 is a ceramic substrate.

A plurality of LED encapsulation units 2, comprise arranged in matrix in the LED of LED substrate 1 wafer 21, electrically connect the gold thread 22 of LED wafer 21 and be packaged in silica gel 23 on LED wafer 21 and the LED substrate 1.

One bulb shell 3 comprises a connecting seat body 32, is arranged at and connects the fin radiator 31 on the pedestal 32 and be arranged at retainer ring 33 on the fin radiator 31, and above-mentioned LED substrate 1 is fixed in described retainer ring 33 upper ends.

One lampshade 4, fastening is arranged on the retainer ring 33 of above-mentioned bulb shell 3.

The utility model is by the polycrystalline encapsulation mode of a plurality of LED wafers 21, a plurality of LED are encapsulated on the LED substrate 1 and form the great power LED module, form single high-power lamp source (5-20W), avoided many great power LED in the prior art, existed a damage to cause the defective of lamp plate damage by series-parallel mode.The utility model also adopts the aluminium base of high thermal conductivity or the LED substrate 1 of ceramic substrate, and the radiator structure of fin radiator 31 on the bulb shell 3, reduces the operating temperature of LED greatly, effectively avoids light decay, prolongs the service life of LED light fixture.Therefore, high-power LED lighting fixture structure of the present utility model can be widely used in street lamp, bulb lamp, Tunnel Lamp, a series of lighting field of fluorescent lamp.
