Description
Technical field
The present invention relates to liquid LED technology field, refer in particular to the processing technology of a kind of liquid LED.
Background technology
In prior art, for solving LED heat dissipation problem, industry seeks the material of high heat capacity for LED heat conduction, generally fills the various high heat capacity liquid such as water, conduction oil, paraffin oil in lampshade, high heat capacity liquid surrounds LED luminescence chip, so that LED luminescence chip quick heat radiating.
When making liquid LED, by the first fill high heat capacity liquid in LED housing of manual operation, burst housing for preventing heated liquid from expanding, housing reserves cavity during fill high heat capacity liquid, this cavity has air；In housing after fill high heat capacity liquid, by manual operation, light emitting host is inserted in housing, due to the existence of air pressure in housing hollow, light emitting host is difficult to insert in housing, therefore, is placed in advance in nylon wire the most in the housing, it is inserted in housing, make air overflow by the gap formed between nylon wire and housing and light emitting host so that light emitting host may be inserted in housing, after inserting light emitting host, extract nylon wire；Carry out welding after inserting light emitting host and form liquid LED.
But, described liquid its cost of labor of LED processing technology is higher, is placed in advance in nylon wire in the housing, and light emitting host is inserted in housing, then extracts nylon wire out, and technique is complex, increases cost of manufacture；Meanwhile, still having air in housing hollow, the heat that light emitting host luminescence produces makes gas expansion, and air pressure increases and temperature rise is accelerated, and affects the service life of light emitting host, and, air pressure increase makes the internal stress of housing increase, and affects the service life of housing.
Summary of the invention
It is an object of the invention to provide the processing technology of a kind of liquid LED, the liquid LED cooling effect that this technique makes is preferable so that the power of liquid LED can reach 15W, and service life is longer.
For reaching above-mentioned purpose, the solution of the present invention is:
The processing technology of a kind of liquid LED, comprises the following steps:
One, fill radiator liquid in the housing of LED, and reserve cavity in the housing；
Two, the light emitting host of LED is placed in housing, between light emitting host and housing, leaves gap；
Three, after light emitting host is placed in housing, put in confined space, and to this confined space evacuation, the reserved cavity making housing is in vacuum state, then being further inserted in housing by light emitting host, light emitting host and housing are interference fit so that light emitting host and housing junction are sealing state；
Four, light emitting host is inserted the junction welded seal after housing, completes the making of liquid LED.
Further, before light emitting host is inserted in housing, also include light emitting host aligning step, make light emitting host insert in housing and do not offset.
Further, after being inserted in housing by light emitting host, also include opening confined space and releasing the sealing step of confined space.
Further, the junction welded seal after light emitting host inserting housing is laser welding.
After using such scheme, the liquid LED made by processing technology of the present invention, owing to the cavity of fill radiator liquid housing is vacuum state, therefore, during radiator liquid expanded by heating, the housing hollow pressure of vacuum state no longer increases, so that radiator liquid temperature is unlikely to rise rapidly, the power making liquid LED can reach 15W, meanwhile, housing hollow pressure is less, less to the internal stress of housing, the service life making liquid LED is longer, and housing is preferable with the sealing effectiveness of light emitting host.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Refering to shown in Fig. 1 to Fig. 5, the processing technology of a kind of liquid LED that the present invention discloses, comprise the following steps:
One, fill radiator liquid 11 in the housing 1 of LED, this radiator liquid 1 usually various high heat capacity liquid such as conduction oil, paraffin oil, and reserve cavity 12 within the case 1, as shown in Figure 1.
Two, the light emitting host 2 of LED is placed in housing, between light emitting host 2 and housing 1, leaves gap, now, light emitting host 2 is not fully inserted in housing 1, to facilitate evacuation.Arranging LED chip on this light emitting host 2 usually heating column, LED light emitting host 2 can be other arbitrary structures, as shown in Figure 2.
Three, after light emitting host 2 is placed in housing 1, put in confined space 3, and to this confined space 3 evacuation so that the reserved cavity 12 of housing 1 is in vacuum state, is then further inserted in housing 1 by light emitting host 2, now, light emitting host 2 and housing 1 are interference fit so that light emitting host 2 more seals, as shown in Figure 3 with housing 1 junction.
For making light emitting host 2 will not offset when inserting in housing 1, improve and insert accuracy rate, before light emitting host 2 is inserted in housing 1, light emitting host 2 can be corrected, cylinder can be set in light emitting host 2 both sides and be corrected.
Four, light emitting host 2 is inserted the junction welded seal after housing 1, as shown in Figure 4, completes the making of liquid LED, as shown in Figure 5.Described welded seal is usually laser welding, pollution-free, and welded seal effect is preferable.
For making welding effect preferable, and it is easy to automation mechanized operation, after light emitting host 2 is inserted in housing 1, confined space 3 can be opened and release the sealing of confined space.
The liquid LED that the present invention makes, owing to the cavity 12 of fill radiator liquid housing 1 is vacuum state, during radiator liquid 11 expanded by heating, housing 1 cavity 12 pressure of vacuum state no longer increases, so that radiator liquid 11 temperature is unlikely to rise rapidly, the power making liquid LED can reach 15W, meanwhile, housing 1 cavity 12 pressure is less, less to the internal stress of housing 1, the service life making liquid LED is longer, and housing 1 is preferable with the sealing effectiveness of light emitting host 2.
The foregoing is only the preferred embodiments of the present invention, not the restriction to this case design, all equivalent variations done according to the design key of this case, each fall within the protection domain of this case.
