Research report shows that LED illumination application progressively meets highway, tunnel, subway, airport, shipping etc. to illumination The higher market demand of the reliability requirement of product.In addition, in explosion-proof lamp, semiconductor manufacturing illumination, low temperature illumination, ultraviolet disappear Poison, lighting for medical use etc. are special, special illuminate is applied also progressively using the LED light product-derived of more advantage.

As miniaturization of electronic products, low-power consumption trend are imperative, therefore end product manufacturers are to various Component proposes small form factor requirements, and LED is no exception.At present, as single LEDs chip power and brightness etc. are constantly lifted, On the premise of heat dissipation technology is continued to optimize, LED illumination product vendor all has more the LED productions of volume advantage in active development Product, the miniaturization of LED illumination product and integrated turn into developing direction.

Although current LED illumination product brightness is high, power saving, generally existing circuit structure is complicated, drives module swelling Swollen, in order to solve the heat dissipation problem of too fat to move driving module, necessity of making use of momentum is designed proprietary installing space in light fixture, increased Production cost and maintenance cost.

Utility model content

The purpose of this utility model is to provide a kind of circuit board assemblies for LEDbulb lamp, with compact circuit structure To save installing space, and reduce production cost.

Another object of the present utility model is to provide a kind of LEDbulb lamp, to overcome current LED lamp bulb structure complicated, The problem of cost and high maintenance cost.

To achieve these goals, the circuit board assemblies of the present utility model for LEDbulb lamp include pcb board and setting The driving module of some LED light sources and driving the LED light source work on the pcb board, some LED light sources are in ring Shape is distributed on the periphery of the pcb board, and the driving module is distributed in the central area of the pcb board and by some LED Light source is surround, and the driving module includes spaced apart bridge rectifier, constant current integrated circuit and current-limiting resistance, described Constant current integrated circuit and the LED light source and current-limiting resistance laod network in series, the bridge rectifier are used for and outside AC power connects and AC power is converted into laod network described in direct-current power supply.

Compared with prior art, the LED light source of the circuit board assemblies of the present utility model for LEDbulb lamp and driving mould Group is arranged on same pcb board and by the conductive coating mutual conduction on pcb board, saves installing space, compact-sized；Together When, because driving modular circuit structure is simplified, heat dissipation capacity is small, and driving module and LED light source are arranged on not shadow on a pcb board Ring the radiating effect of LED light source；Bridge rectifier, constant current integrated circuit and the current-limiting resistance interval cloth of composition driving module Put, beneficial to radiating, effectively reduce bridge rectifier, the electromagnetic interference of constant current integrated circuit and current-limiting resistance from each other；LED Light source is annularly arranged so that light beam is concentrated, and intensity of illumination is high.

It is preferred that the driving module also includes the safety piece being connected in series with the bridge rectifier, the bridge-type is whole Stream device is electrically connected by the safety piece with external communication, protects the driving module from the impact of abnormal current.

It is preferred that be connected in series between some LED light sources, though a LED light source because short circuit is broken down, Other LED light sources can also continue to work.

It is preferred that the pcb board is circle, and then play a part of saving installing space.

In order to realize that above-mentioned another object, LEDbulb lamp of the present utility model, including enclosed globe shade steep and installed in the ball The circuit board assemblies as described above for being used for LEDbulb lamp in shape cover bubble.

Compared with prior art, LEDbulb lamp of the present utility model can have by the circuit board assemblies for LEDbulb lamp Effect saves the installing space of enclosed globe shade bubble, reduces production cost；Therefore LEDbulb lamp of the present utility model can not only be to miniaturization Direction is developed, moreover it is possible to improves illumination, reduces production cost.
