Description

A kind of integrated full-color COB packaged light source with control circuit

Technical field

The utility model relates to LED light source technical field, especially relates to a kind of COB packaged light source with control circuit.

Background technology

In LED application, LED module is because of its super brightness, and the features such as low-power consumption, long service life, simple installation, are widely used in the places such as advertising lamp box, mark signboard, publicity Warning Mark.Along with the maturation gradually of LED module technology, its range of application will be more extensive.

Existing LED main flow is packaged with SMD encapsulation mode and COB encapsulation mode, in general, SMD packaging thermal resistance is large, and poor radiation, there is glare problem, in the time of application end, device need to be attached on fixing substrate, can only be applied to the less demanding lighting field of properties of product, existing COB encapsulation is packaged with certain performance boost and cost advantage with respect to SMD, because chip is directly to encapsulate on substrate, save the supporting structure layer in SDM, so corresponding thermal resistance is low, thermal diffusivity is good, Material Cost also can reduce, also avoided glare problem.But existing SMD device and COB device all need to configure in addition corresponding power supply and processing apparatus in the time being applied to lighting field, its chips has and takies that semiconductor volume is large, cost is higher, establishes the shortcomings such as stability under electric capacity long-term continuous operation in period is poor in chip, thereby it is very high to cause power supply electric energy conversion efficiency all can not arrive, and has increased power supply cost.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of integrated COB packaged light source with control circuit, in order to solve the problems of the technologies described above.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of integrated full-color COB packaged light source with control circuit, comprise PCB substrate, LED luminescence chip, capacitor and be integrated in the substrate circuit circuit on PCB substrate, wherein substrate circuit circuit is provided with LED luminescence chip circuit, rectification circuit, flow control circuit; Described PCB substrate surface is coated with copper membrane; On described copper membrane, be welded with button capacitor, this button capacitor is in parallel with the DC output end of rectification circuit.

As preferably, described full-color COB packaged light source can encapsulate All colour light source can be packaged into again white light source.

The utility model is designing and arranging cloth control IC and relevant components and parts on substrate, control circuit are become built-in, on light source and control integration to block aluminum-based circuit board plate, both provide cost savings, and save assembling volume and time again.

The beneficial effects of the utility model are: 1) light source and power supply components and parts integrated combination are integrated, easy to install.

2) reduced cost.

3) less with respect to light source and power supply discrete device volume, the scope of application is wider.

4) color transformed control is convenient.

The specific embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.

Fig. 1 is structural representation of the present utility model.As shown in Figure 1, a kind of integrated full-color COB packaged light source with control circuit, mainly by PCB substrate 2, LED luminescence chip 6, capacitor 7 be integrated in substrate circuit circuit 5 on PCB substrate 2 etc. and form.Wherein LED luminescence chip 6 is fixed on PCB substrate 2 by chip positioning glue, substrate circuit circuit 5 is provided with LED luminescence chip circuit 8, rectification circuit 3, flow control circuit 4, wherein rectification circuit 3 and flow control circuit 4 are installed on the design attitude of described substrate circuit circuit 5, and LED luminescence chip circuit 8 is distributed on substrate circuit circuit 5.PCB substrate 2 surfaces are coated with copper membrane 1, and LED luminescence chip 6 welds by aluminum steel and copper membrane 1.On described copper membrane 1, be welded with button capacitor 7, this button capacitor 7 is in parallel with the DC output end of rectification circuit 3, and the pulsating volage that this capacitor 7 is exported rectification circuit 3 changes voltage stabilizing state voltage into.220V alternating voltage is converted into 220V DC voltage by rectification circuit 3, the DC current of 220V is controlled to continuous current by flow control circuit 4 on described substrate circuit circuit 5, and the continuous current of 220V drives the LED luminescence chip circuit 8 on substrate circuit circuit 5 to control LED luminescence chip 6.By by LED luminescence chip 6 and the disposable welding of button capacitor 7 and sealing protection, make that COB encapsulation volume is little, thin thickness, packaging cost be low.

The utility model, by designing and arranging cloth control IC and relevant components and parts on substrate, becomes control circuit built-in, on light source and control integration to block aluminum-based circuit board plate, both provides cost savings, and saves assembling volume and time again.
