Lens unit, light source module and light-emitting device

Abstract

The invention discloses a lens unit, a light source module and a light-emitting device. The lens unit comprises a connecting piece and a plurality of lens elements, wherein the connecting piece has a first thickness; each lens unit comprises a light shaping part and a base part; each base part has a second thickness, and surrounds the light shaping part; the second thickness is smaller than the first thickness; each base part is connected to the connecting piece; the upper surface of each base part and the upper surface of the connecting piece are positioned on the same horizontal plane. By adopting the lens unit disclosed by the invention, the assembly procedure and assembly time for assembling the lens unit on a light-emitting unit can be shortened.

Description

technical field [0001] The invention relates to a lens unit, a light source module and a light emitting device, in particular to a contiguous lens unit, a light source module and a light emitting device with the contiguous lens unit. Background technique [0002] Cooperate with reference figure 1 and figure 2 , are respectively an exploded perspective view and a cross-sectional view of a conventional light-emitting device. The light emitting device 5 includes a circuit board 50 , a plurality of LEDs 52 , a plurality of lens elements 54 , a waterproof element 56 and a cover 58 . The circuit board 50 is a flat plate, and the light-emitting diodes 52 are arranged in groups of two and equally spaced on the circuit board 50 and are electrically connected with the circuit board 50; the lens elements 54 are correspondingly arranged on the light-emitting diodes 52 for redistribution. light from the LED 52, and output a light with a specific light intensity. The waterproof membe...

AI Technical Summary

Problems solved by technology

Although the lens unit 62 can effectively reduce the assembly process and assembly time for assembling the lens unit 62 and the light emitting diode 61, yet, the volume of the base 620 for riding the lens element 622 is much larger than the lens element 622, thus, it will increase The amount of production materials used, resulting in an increase in production costs

Secondly, when the thickness of the sheet-shaped lens unit 62 is too thin, the rubber material cannot be injected into the mold smoothly, and when the thickness of the lens unit 62 increases, the overall height of the light emitting device increases.
