Description

Multicolor LED light source

Technical Field

The utility model relates to a LED light source technical field especially relates to a polychrome LED light source.

Background

With the greatly improved luminous efficiency and the continuous reduction of the cost of the LED wafer, the lighting product with the LED wafer is widely applied, especially, the adjustment of different light colors of the multicolor LED light source is widely favored by users, but because the multicolor LED light source needs to coat different fluorescent powder layers on different LED wafers in the processing process, the size of a single multicolor LED light source is very small, when the mechanical arm often coats the fluorescent powder layer, part of the fluorescent powder layer leaks or is coated on the adjacent LED wafer, and the lighting of different products has great difference.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a multicolor LED light source, which can effectively prevent a part of the phosphor layer from leaking or coating on the adjacent LED chip when the phosphor layer is coated.

The utility model discloses a solve its technical problem and the technical scheme who adopts provides a polychrome LED light source, including base and the pin of setting on the base, the base is equipped with open-top's base inner chamber, the bottom surface of base inner chamber is equipped with the mounting groove, be equipped with at least one LED wafer in the mounting groove and cover a phosphor powder layer of whole LED wafer No. one, the bottom surface of base inner chamber is equipped with a plurality of LED wafer No. two around the mounting groove distribution, no. two LED wafer go up the coating respectively and have No. two phosphor powder layers, the reason is higher than the upper surface of a LED wafer on the inside wall of mounting groove so that do not leak when coating a phosphor powder layer.

As a further improvement of the utility model, the bottom surface of the inner cavity of the base is provided with a baffle frame which is enclosed into a mounting groove.

As a further improvement of the utility model, the mounting groove is a concave position arranged on the bottom surface of the inner cavity of the base.

As a further improvement of the utility model, the base includes light source support and heat conduction frame, and a LED wafer sets up on the heat conduction frame with No. two LED wafers.

The utility model has the advantages that:

1. the height of the upper surface of the mounting groove is lower than that of the upper surface of the base; a LED wafer coating in the mounting groove has a fluorescent powder layer, and the No. two LED wafers of base inner chamber scribble No. two fluorescent powder layers respectively, and the luminous colour of No. one LED wafer is different with No. two LED wafers, and No. two LED wafers are around the mounting groove setting colour mixture when can making luminous more even.

2. A fluorescent powder layer of mounting groove directly covers whole LED wafer so that the degree of difficulty of coating reduces, improves production efficiency, reduces the processing cost.

3. The heat conduction frame with good heat conductivity is inserted into the base, so that heat generated by the LED wafer in the working process can be dissipated through the heat conduction frame, and light emitting failure caused by high temperature is avoided.
