Abstract
The utility model relates to a high-efficiency heat dissipating power-supply-integrated LED light source module. The high-efficiency heat dissipating power-supply-integrated LED light source module comprises a PCB (printed circuit board) for electric connection and a plurality of LED chips arranged on the surface of the PCB, wherein the PCB and the LED chips are connected through sheet tinned copper foil heat sinks, and the PCB is also provided with an LED power supply. The high-efficiency heat dissipating power-supply-integrated LED light source module can protectively reduce the junction temperature of the LED chips well and prolong the service life; due to the fact that a PTC (positive temperature coefficient) thermistor current-limiting high-voltage mains supply direct-drive power supply and LED light sources are integrated on one circuit board to form the power-supply-integrated module, mass production is facilitated, and the metal material consumption can be reduced to the largest extent. The material cost is saved and the mass production is obtained, the production efficiency and the product reliability can be largely improved, and the cost and the fault rate can be reduced obviously.
Description
Technical field

Background technology
When LED light source is luminous, also can produce a large amount of heat, if these heats are not left and will shorten the service life of LED light source.The above high power LED light source of tradition 1W will complete electrical connection and heat radiation by metal or ceramic base wiring board, the heat sink light source module that is combined into, but metal base circuit board exists a thermal conductivity factor to be difficult to surmount the insulating barrier of 3w/mk in order to realize electrical isolation between electrical connection layer and metal substrate, thermal conductivity factor also is difficult to surmount 150w/mk although ceramic substrate does not structurally have insulating barrier, and complex process is expensive.So the metal base circuit board of extensive use at present becomes the maximum bottleneck on LED chip and lamp cooling structure passage, so which kind of efficient radiator structure light fixture adopts all can't tackle the problem at its root, finally cause a large amount of heat accumulation of LED chip, have a strong impact on the service life of LED light source.
The utility model content
In order to address the aforementioned drawbacks and deficiency, the utility model embodiment provides a kind of junction temperature better and the high efficiency and heat radiation power supply integration LED light source module of long service life.Described technical scheme is as follows:
The utility model proposes a kind of high efficiency and heat radiation power supply integration LED light source module, comprise for the PCB circuit board that is electrically connected and several LED chips of being located at its surface, it is characterized in that, described PCB circuit board by zinc-plated heat sink connection of Copper Foil matter of sheet, also is provided with LED power supply on described PCB circuit board with LED chip.
Preferential as technique scheme, described PCB circuit board is fixedly connected with setting by high thermal conductive silicon film metallic heat dissipating part.
Preferential as technique scheme, described zinc-plated Copper Foil matter is heat sink is two-sided Via Design.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: the utility model relates to a kind of power supply integration LED light source modular structure; can better protect and reduce the LED chip junction temperature; increase the service life; and PTC thermistor current limliting high pressure civil power is directly driven to power supply and LED light source be integrated on a wiring board and make the power supply integration module; be convenient to batch production, and reduced to greatest extent the consumption of metal material.Not only saved material cost but also be convenient to batch production, can greatly enhance productivity and product reliability, be significantly reduced to originally and fault rate.
