Technical field

The present invention relates to optical device manufacture fields, and in particular to a kind of optical module and its light engine installation method.

Background technique

In the production technology of 100G/400G/800G high-speed optical module, having a step is to carry out light engine and shell Fixed technique, for solving the problems, such as that light engine radiates, and in the prior art, the step mostly use greatly welding procedure or Person is that the two is fixed greater than the elargol of 80HD using hardness, but due to there is biggish stress in this way, so being easy to make At housing distortion, the loss of optical path is further caused to increase.

Therefore, a kind of novel optical module and its light engine installation method are designed, is always this field primary study Problem.

Summary of the invention

The technical problem to be solved in the present invention is that in view of the above drawbacks of the prior art, provide a kind of optical module and its Light engine installation method overcomes the defect that existing method be easy to cause housing distortion, causes optical path loss big.

The technical solution adopted by the present invention to solve the technical problems is: providing a kind of optical module, the optical module includes Light engine and shell, preferred embodiment are: the optical module further include for for be arranged light engine and shell it Between fixed structure, the fixed structure includes fixing piece and the elargol layer for wrapping part, wherein the elargol hardness is 25-55HD。

Wherein, it is copper wire or optical fiber that preferred version, which is the fixing piece, the fixing piece with a thickness of 100-150um.

Wherein, preferred version is the elargol with a thickness of 100-150um.

Wherein, preferred version is the 50%-70% that the coated area of the elargol is shell.

To solve this technical problem, the present invention also provides a kind of light engine installation method of optical module, preferred embodiments It is, the light engine installation method is applied in optical module as described above, comprising the following steps:

Elargol is coated on shell；

Fixing piece is put into elargol；

Light engine is placed on fixing piece, and is come into full contact with；

Elargol is toasted, its solidification is made.

Wherein, preferred version is that the light engine installation method is further comprising the steps of:

After light engine is placed on fixing piece, applies pressure for light engine and press to shell.

Wherein, preferred version is that the light engine installation method is further comprising the steps of: soft elargol is coated in shell On.

Wherein, preferred version is the high-speed optical module that the optical module is 100G/400G/800G.

The beneficial effects of the present invention are compared with prior art, the present invention is by designing a kind of optical module and its optics Engine installation method, the fixation kit formed using the soft elargol by 30-50HD and the fixing piece being arranged in soft elargol, instead of Original welding uses the elargol for being greater than 80HD, and the stress generated when reducing fixed to prevent housing distortion, and then subtracts Few optical path loss.

Detailed description of the invention

Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:

Fig. 1 is a kind of structural schematic diagram of optical module in the present invention；

Fig. 2 is the structural schematic diagram of fixed structure in the present invention；

Fig. 3 is a kind of flow chart of the light engine installation method of optical module in the present invention.

Specific embodiment

Now in conjunction with attached drawing, elaborate to presently preferred embodiments of the present invention.

As Figure 1-Figure 2, the present invention provides a kind of most preferred embodiment of optical module.

A kind of optical module, with reference to Fig. 1, the optical module includes light engine 100, shell 200 and for for being arranged Fixed structure 300 between light engine 100 and shell 200, with reference to Fig. 2, the fixed structure 300 includes fixing piece 310 And wrap the elargol layer 320 of part 310, wherein the elargol hardness is 25-55HD.

Specifically, elargol refers mainly to electric conductivity elargol, and the electric conductivity elargol is a kind of solidification or has after dry certain The adhesive of electric conductivity, it usually using matrix resin and conductive filler, that is, conducting particles as main constituents, passes through matrix The bonding effect of resin is combined together conducting particles, forms conductive path, realizes and is glued the conductive connection of material, and by leading Electric direction is divided into isotropic conductivity elargol and anisotropic conductive elargol.

LED light engine refer to comprising LED encapsulation (component) or LED array, LED driver and other brightness, calorifics, The mechanically and electrically entire combination of pneumatic module.

Wherein, due to the elargol for using hardness to be greater than 80HD in the prior art, carry out light engine and shell There are biggish stress in fixed process, it is be easy to cause housing distortion, and then optical path loss is caused to increase, and is adopted in the present invention The soft elargol for being 25-55HD with hardness and the components of fixed thickness are introduced to control the thickness of elargol, substitute the prior art Used in hardness be greater than the elargol of 80HD, can greatly improve the big problem of stress, and then reduce since housing distortion draws The optical path loss risen, in the case where guaranteeing optical module perfect heat-dissipating, so that the optical property of optical module is more stable.

Further, the fixing piece 310 be copper wire or optical fiber, the fixing piece 310 with a thickness of 100-150um.

It wherein, using the fixing piece of fixed thickness 310 is asked for solve that the thickness of elargol layer 320 is not easily controlled Topic.

Wherein, the elargol with a thickness of 100-150um.

Wherein, the coated area of the elargol is the 50%-70% of shell.

As shown in figure 3, the present invention also provides a kind of most preferred embodiments of the light engine installation method of optical module.

A kind of light engine installation method of optical module, the light engine installation method are applied in optical mode as described above In block, comprising the following steps:

S1, elargol is coated on shell；

S2, fixing piece is put into elargol；

S3, light engine is placed on fixing piece, and come into full contact with；

S4, baking elargol, make its solidification.

Further, the light engine installation method is further comprising the steps of:

Further, elargol is coated on shell, the soft elargol for being 25-55HD using hardness.

Further, the optical module is the high-speed optical module of 100G/400G/800G, since optical module is transported in high speed A large amount of heat is easy to produce during row, therefore the present invention devises a kind of side for optimizing light engine and shell fixed effect Method, for guaranteeing the heat dissipation performance of the high-speed optical module.

Specifically, the soft elargol that hardness is 25-55HD is coated uniformly on shell, then is put into fixed thickness in elargol Fixing piece further, light engine is placed on fixing piece for solving the problems, such as that its fixed thickness is not easily controlled On, apply pressure for light engine and press to shell, due to the soft elargol for being 25-55HD using hardness, so only needing slightly It is micro- firmly push, come into full contact with the component of light engine and fixed thickness, finally toast elargol, make its solidification both can, compare In the elargol for the 80HD that the prior art uses, does not need to use very big pressure that light engine is fixed with shell, effectively subtract The small optical path loss due to caused by housing distortion.

As described above, only preferred embodiment is not intended to limit the scope of the present invention, Fan Yibenfa Equivalent change or modification made by bright claim is all that the present invention is covered.
