Problems solved by technology

[0004] In the above structure, since the lenses 40a need to be combined on the LED chip 20a respectively, the overall assembly time and cost are increased. In addition, the number of the grooves 11a is large and dense, thus requiring a larger substrate area. Affect the strength of the substrate 10a, easily cause the substrate 10a to crack, thereby reducing the product yield

Abstract

The invention discloses a multi-groove light emitting device, which comprises a base, a blue light emitting unit, at least two red light emitting units, a light conversion layer and a lens. The base has a central groove and at least two symmetrically arranged outside the central groove. The side groove, the blue light-emitting unit is set in the central groove, the two red light-emitting units are respectively arranged in the two side grooves, the light conversion layer covers the blue light-emitting unit, the lens is convexly set on the base, and sealed A central groove and at least two side grooves; thereby increasing the light extraction efficiency of the LED chip, improving product yield, and reducing overall assembly time and cost.

Description

technical field [0001] The invention relates to a light emitting device, in particular to a multi-slot light emitting device capable of emitting warm white light. Background technique [0002] Light Emitting Diodes (Light Emitting Diode, LED) have gradually replaced traditional tungsten lamps, fluorescent lamps or mercury lamps and are widely used in various lamps due to their advantages such as low energy consumption, power saving, long service life, small size, and fast response. . [0003] Please refer to figure 1 and figure 2 As shown, they are respectively a schematic plan view and a partial cross-sectional view of an existing LED light-emitting module; the LED light-emitting module 1a includes a substrate 10a, a plurality of LED chips 20a (such as blue LED chips 20a), fluorescent glue 30a such as (yellow fluorescent glue 30a) And a plurality of lenses 40a, the substrate 10a is provided with a plurality of grooves 11a arranged in an array, the LED chips 20a are resp...
