Abstract

The utility model discloses an LED (light-emitting diode) integration module. The LED integration module consists of a uniform light component, a reflecting plate and a substrate which are arranged sequentially from the top down, wherein a plurality of LED luminous bodies are encapsulated on the substrate; the reflecting plate is provided with through holes which are used for making the LED luminous bodies extended upwards; the luminous areas of the LED luminous bodies are positioned above the reflecting plate; and the uniform light component is arranged above the LED luminous bodies. According to the LED integration module, the plurality of LED luminous bodies are encapsulated on the substrate in advance and then are integrated into a PCB (printed circuit board), so that the LED luminous bodies are only required to be simply sorted, the requirement and the cost of testing and sorting of the LED luminous bodies are reduced, a light blending effect can be ensured, a heat dissipation effect is improved, and the illumination cost is reduced.

Description

The LED integration module

Technical field

The utility model relates to a kind of lighting module, is specifically related to a kind of LED integration module.

Background technology

Led light source is as a kind of effective energy-saving green product, increasing being applied in the various illuminators.In traditional illuminator, normally earlier the LED luminous element is packaged into single individual LED luminous tube, and then a plurality of LED luminous tubes are integrated on the pcb board.

There is following shortcoming in traditional illuminator: the work calories derivation efficient of LED luminous element is low, and LED luminous element temperature will sharply rise, thereby causes the LED light efficiency to reduce the lost of life.Simultaneously; Because human eye is very responsive to the color and the brightness of light; As if the visual effect of wanting to reach desirable; Will guarantee the consistency of characterisitic parameters such as LED luminous flux, must carry out strict test and sorting to every LEDs luminous element, otherwise wavelength be inhomogeneous or the inhomogeneous of brightness all can let the people produce uncomfortable feeling.In order to guarantee the good consistency of characterisitic parameter such as LED wavelength, the sorting after from chip testing to encapsulation all will be satisfied certain requirement, and test will improve with the cost of sorting greatly, and promptly the cost of the Lights section increases greatly in the illuminator.

The test of LED luminous element and sorting are the operations of necessity of LED supplier, have become at present the production capacity bottleneck of many LED luminous elements manufacturer, also are important sources of LED luminous element cost.Before the uniformity of epitaxial wafer was controlled, relatively efficient ways was to reduce the test and the sorting cost of chip.

For addressing the above problem, the test of a kind of LED of reduction, the requirement of sorting need be provided, reduce the led module of LED luminous element sorting cost.

Summary of the invention

The goal of the invention of the utility model provides a kind of LED integration module, through the improvement of structure, only needs the LED luminous element is carried out simple sorting; Thereby reduce the test of LED luminous element, the requirement and the cost of sorting; Can also guarantee the mixed light effect, improve radiating effect, thereby reduce illumination cost.

For reaching the foregoing invention purpose; The technical scheme that the utility model adopts is: a kind of LED integration module; Said LED integration module is made up of the even optical assembly, reflecting plate and the substrate that set gradually up and down, is packaged with a plurality of LED luminous elements on the said substrate, offers on the said reflecting plate to supply the upwardly extending through hole of said LED luminous element; The light-emitting zone of said LED luminous element is positioned at the top of this reflecting plate, and said even optical assembly is arranged at the top of said LED luminous element.

In the preceding text, said substrate can be an arbitrary shape, to satisfy different occasion illumination needs.

When said LED luminous element was the white light LEDs luminous element, said even optical assembly was formed by even tabula rasa and folded the establishing of astigmatism plate.

When said LED luminous element was the blue-ray LED luminous element, said even optical assembly was formed by even tabula rasa and folded the establishing of plane silica gel fluorescent powder film.Through said structure, the silica gel fluorescent powder film converts white light to the blue light that the blue-ray LED luminous element sends through the plane.

In the technique scheme, said LED luminous element is packaged on the said substrate through transparent silica gel, COB packaged type promptly commonly used, but the packaged type of LED luminous element is not limited to the COB encapsulation, can also adopt the SMT encapsulation.

In the technique scheme, the below of said substrate is provided with heating panel, and the heat of the luminous generation of LED luminous element is effectively left.

Because the technique scheme utilization, the utility model compared with prior art has advantage:

1. the utility model is packaged in a plurality of LED luminous elements on the substrate in advance; And then be integrated on the pcb board; So only need the LED luminous element is carried out simple sorting, reduced the test of LED luminous element, the requirement and the cost of sorting, can also guarantee the mixed light effect; Improve radiating effect, thereby reduce illumination cost.

2. when the LED luminous element of the utility model is the blue-ray LED luminous element, above module, cover one deck plane silica gel fluorescent powder film, the upper surface of plane silica gel fluorescent powder film is an exiting surface, and the light that the LED integration module is sent is white light.

3, the utility model adopts packaged types such as COB or SMT that the LED luminous element is packaged on the substrate, and encapsulation is reliable, improves luminous efficiency.
