Abstract

The utility model provides an integrated large-power LED (light-emitting diode) light source capable of improving whole luminescent efficiency. The key points of the technical scheme of the light source are as follows: the light source comprises LED luminescent chips and a bracket for fixing the LED luminescent chips; the LED luminescent chips are arranged in the bracket in the form of a matrix; a welding wire platform is arranged between the two adjacent rows of luminescent chips; and the two adjacent rows of luminescent chips can be electrically connected with each other by the welding wire platform. In the light source, by changing the structure of the light source bracket, the connecting and combining mode between the chips can be changed, so that current influenced by the cascading of many chips is dispersed to a plurality of parallel circuits, thus realizing the aim of equally dividing the current, reducing the influence of a single LED chip on the whole light source, and solving the problems that an LED integrated light source is easy to shut down and the light attenuation is large.

Description

The integrated high power LED light source

Technical field

The utility model relates to the LED technical field, more particularly, relates to a kind of integrated high power LED light source.

Background technology

Integrated high power LED is very extensive in business-like concrete application, can be applicable to high-power illumination, as outdoor lightings such as street lamp, bulkhead lamp capable, explosion-proof lamps.And the connected mode of LED load circuit is directly connected to LED component reliability and service life.This is because led circuit that can trouble free service, and its basic function mainly contains two aspects: the one, keep constant electric current as far as possible.The 2nd, drive circuit should keep lower oneself power consumption, so just can make the system effectiveness of LED keep high levels.

Using more at present, the form of LED connecting circuit mainly contains: series, parallel, series connection/parallel connection combination etc.Adopt different LED connected modes for LED use and all most important to designing requirement of drive circuit etc.Therefore in the combination of side circuit, correctly select the LED connected mode for improving its illumination effect, functional reliability, simplified driving circuit design and processing, and the efficient etc. that improves entire circuit all has positive meaning.

Existing high-power integrated optical source, the mode of connection of inside chip is all used string back compound mode also earlier, after being single branch road series connection, again by the compound mode of a plurality of branch road parallel connections, shown in the schematic diagram of existing integrated high power LED light source inside chip schematic diagram of Fig. 4 and the existing integrated high power LED light source internal circuit of Fig. 5.The shortcoming of this mode be LED lamp on single branch road in the long-term process of using, if when single or a few LEDs occurring and damaging, it is uneven to cause electric current to distribute, and influence the illumination effect of whole light source, accelerated ageing, reduction life-span.

The utility model content

The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of integrated high power LED light source that improves whole luminous efficacy is provided.

In order to achieve the above object, the utility model is to be achieved by following technical proposals: a kind of integrated high power LED light source comprises the LED luminescence chip, is used for fixing the support of LED luminescence chip; Described LED luminescence chip is matrix and arranges in support; Be provided with the bonding wire platform between the described adjacent two row luminescence chips; Described adjacent two row luminescence chips are electrically connected by the bonding wire platform.

Described bonding wire platform is the bonding wire platform that conductor is made, and then adjacent two row luminescence chips are electrically connected by the bonding wire platform; Perhaps described bonding wire platform is provided with conductor bar, and then adjacent two row luminescence chips are electrically connected with realization on the bonding wire platform by wire bonds.

Described bonding wire platform is fixed on the support of LED luminescence chip, and frame bottom is provided with fin.

The utility model is to use like this: shown in Fig. 3 light source internal circuit diagram, the LED luminescence chip is to be arranged on the support with matrix form, and circuit power is arranged on the left side of chip, and the sense of current by the LED luminescence chip is from left to right.

Compared with prior art, the utlity model has following advantage and beneficial effect:

1, the utility model passes through to change the structure of light source bracket, thereby changes the connection compound mode of chip chamber, makes the electric current of original multicore sheet series connection influence be distributed to a plurality of parallel circuits, reduces the influence of single LEDs chip to whole light source.

2, light-source structure of the present utility model can solve the easily dead lamp of LED integrated optical source, the problem that optical attenuation is big with the current uniform of circuit.
