Abstract

A kind of light-emitting assembly packaging structure a comprising optical lens；One frame is equipped with one first open end and one second open end, and optical lens setting is engaged in first open end, and the optical lens is engaged with the setting of the first open end and constituted with the engagement of insert molding technique；One substrate is engaged with the second open end of the frame, which is equipped with a light emitting source, which covers at the light emitting source.The utility model, which reaches, to be avoided fixing so that being coated with bonding between optical lens and frame with viscose, and it avoids so that the assembling between optical lens and frame engages out-of-flatness, therefore structure can be made more firm, and the cost of material is low without using viscose event, and the secondary operation program of the gluing between optical lens and frame, assembling is saved, reach effect.

Description

A kind of light-emitting assembly packaging structure

Technical field

The utility model relates to a kind of encapsulating structure more particularly to a kind of light-emitting assembly packaging structures.

Background technique

In light emitting module, common application be light emitting diode (Light-emitting diode) or two pole of laser Manage the luminescence component of (Laser diode), and such as vertical cavity surface emitting laser (VCSEL) (Vertical of laser diode form Cavity Surface Emitting Laser, VCSEL) luminescence component.In such VCSEL luminescence component, the common tool of structure There are a substrate (substrate), a frame (holder) and an optical mirror slip (optical lens), and frame also can be one kind Lid (cap) form.

In this technical solution, the assembling between frame and optical mirror slip is engaged, and the prior art is often with viscose by frame It is mutually binded with optical lens, since the amount of its viscose coating when viscose, which is coated with, to be binded may be unequal, uneven, it will so that Assembling between frame and optical mirror slip makes structure built on the sand when engaging out-of-flatness and bad gluing, and when viscose is by the time Weathering be easy to cause frame to separate with optical mirror slip, and has the problems such as glueing material at high cost, complex procedures.

Utility model content

In view of described in the prior art, thus the utility model aims to solve and improve the problems of the prior art with For the purpose of defect.

In order to reach the above object, the utility model provides a kind of light-emitting assembly packaging structure comprising: an optical lens Mirror；One frame is equipped with one first open end and one second open end, and optical lens setting is engaged in first open end, and The optical lens is engaged with the setting of the first open end to be constituted with the engagement of insert molding technique；One substrate, second with the frame Open end engages, which is equipped with a light emitting source, which covers at the light emitting source.

Wherein preferably, the optical lens is optical diffusion sheet.

Preferably, the light emitting source is vertical cavity surface emitting laser (VCSEL) component.

Preferably, the lower surface of the optical lens is equipped with a microlens array.

Therefore, the utility model can be made to reach to avoid fixing so that being coated with bonding between optical lens and frame with viscose, And it avoids so that the assembling between optical lens and frame engages out-of-flatness, therefore it is more firm to make structure, and does not use The cost of material is low for viscose event, and saves the secondary operation program of the gluing between optical lens and frame, assembling, reaches effect.

Specific embodiment

In order to further have a clear understanding of the content of the utility model, added with the following example collocation attached drawing and symbol It, please be refering to explanation.

Referring to Fig. 1, the utility model provides a kind of light-emitting assembly packaging structure comprising: an optical lens 1, a frame Frame 2 and a substrate 3.

The optical lens 1 can be common glass or plastics, preferably, the optical lens 1 is optical diffusion sheet (diffuser lens).The frame 2 is equipped with one first open end 21 and one second open end 22, the optical lens 1 setting engagement In first open end 21, and the optical lens 1 is engaged with the setting of the first open end 21 with insert molding technique (Insert Molding) engagement is constituted.The substrate 3 is engaged with the second open end 22 of the frame 2, which is equipped with a light emitting source 4, The frame 2 covers at the light emitting source 4.In the present embodiment, which is vertical cavity surface emitting laser (VCSEL) component, the component It can be light source chip pattern.

Please continue to refer to Fig. 2, the wherein setting of the optical lens 1 of the utility model and frame 2 (the first open end 21) Engagement is constituted with the engagement of insert molding technique, by insert is, for example, that optical lens 1 is placed in die cavity, then with certain material example If plastics filling die cavity constitutes for example, frame 2, so that optical lens 1 is integrated with frame 2, avoided in order to this creation can be made to reach It is fixed so that being coated with bonding between optical lens 1 and frame 2 with viscose, and avoids the group so that between optical lens 1 and frame 2 Out-of-flatness is closed in attaching, therefore structure can be made more firm, and without using viscose event, the cost of material is low, and saves optical lens 1 The secondary operation program of gluing, assembling between frame 2, reaches effect.And the utility model insert molding technique is existing Technique is repeated no more in this.Therefore one is projected in the operating principle of the utility model, when can make 4 VCSEL of light emitting source vertically Light beam 100, the light beam 100 are projected by optical lens 1 again, and when optical lens 1 is optical diffusion sheet, then can allow light beam 100 are formed as uniform or specific intensity distribution diffusion light 200.

Preferably, referring again to Fig. 3, wherein the lower surface 10 of the optical lens 1 is equipped with 5 (Micro of a microlens array Lens Array), which can be the array of convex lens.Therefore, by means of the setting of microlens array 5, this can be made The utility model light emitting source 4 light beam 100 emitted when being VCSEL increases it by penetrating for light beam 300, so as to promoting brightness.

Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts Every other embodiment, fall within the protection scope of the utility model.
