Background technology

Manufacturing enterprise on the LED illumination market is a lot of at present, but the LED industry does not also reach standardization and standardization.The policy of country energy savings aspect is widelyd popularize the application of LED, but LED product price height, and quality and spread in performance are uneven, do not obtain popular approval.

A lot of ways have been sought in order to reduce product price by manufacturing enterprise, but almost do not have other way except reducing properties of product.Producing its corresponding circuit diagram of different products will redesign, and makes material and will screen again, causes on-hand inventory wasting of resources problem serious.

Circuit structure under the current techniques is to connect power supply with parallel circuits, and series circuit maintains whole internal circuit.If a led chip generation problem in the series circuit will cause the entire circuit can't normal operation.

In addition, during chips such as the use of making Different Light 0.06W, 0.1W, 0.2W, 0.5W, need redesign the PCB(printed circuit board according to different capacity).According to customer demand, when making the different capacity product, must improve the raw-material stock of PCB; That so easy generation is produced is bad, managerial confusion, problem that enterprises production efficiency is low.

Summary of the invention

The utility model is exactly at the problems referred to above, and a kind of design of standardization LED PCB module and module syndeton that is applicable to multiple led chip and luminous power and long service life is provided.

For achieving the above object, the utility model adopts following technical scheme, and the design of standardization LED PCB module comprises that PCB, PCB are provided with a plurality of led chips, each the led chip parallel connection of its structural feature.

As a kind of preferred version, each led chip described in the utility model is divided at least two groups, the positive and negative of each led chip links to each other by conductor wire travel permit extremely respectively in every group, and each is organized homopolarity and props up the conductor wire travel permit and link to each other with the mains supply line bar by connecting the conductor wire travel permit respectively.

As another kind of preferred version, each led chip is laterally uniform in every group described in the utility model, and a conductor wire travel permit and mains supply line bar are the x wire travel permit, and connecting the conductor wire travel permit is vertical circuit bar.

As another kind of preferred version, led chip described in the utility model is divided into two groups, and every group comprises six led chips.

As another kind of preferred version, PCB described in the utility model is rectangle, and PCB is provided with conduction region for four jiaos, and the conduction region place is provided with the conduction connecting hole; Conduction region links to each other with described mains supply line bar.

Secondly, led chip described in the utility model is bare chip.

In addition, bare chip described in the utility model is combined on the PCB by a glue, thread tacking, and forms luminous mirror by the molding printing.

The module syndeton of standardization LED PCB module design, each led light source PCB module is transversely arranged, and corresponding conduction connecting hole links to each other by Qian shape contact pin.

As a kind of preferred version, led light source PCB module described in the utility model is six.

The module syndeton of another kind of standardization LED PCB module design, each led light source PCB module overlaps, and corresponding conduction connecting hole is by the welding of cylindricality electric conductor.

The utility model beneficial effect.

Each led chip parallel connection of the utility model when making any one inner chip generation non-normal working, can not influence the work of other chip.When the chip of module internal has a little short circuit, to not obviously influence of overall brightness, need not to change immediately entire module, the consumer can continue to use.

The led chip that no matter uses 0.06W still is 0.1W, 0.2W, 0.5W, 1WLED chip, only needs to change quantity and the position of inserting chip, just can reach same luminosity; Therefore adopt the utility model led light source PCB module to need not to use a kind of PCB just can produce the product of different capacity at different LED chip change circuit design.

The utility model is applicable to the 1200mmLED light source, light sources such as Bulb type bulb, street lamp, explosion-proof lamp.
