Description
Technical field
The present invention relates to liquid LED technology field, refer in particular to a kind of manufacture craft 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, in lampshade, usually fill water, conduction oil, the various high heat capacity liquid of paraffin wet goods, high heat capacity liquid surrounds LED luminescence chip, to make LED luminescence chip quick heat radiating.
When making liquid LED, by manual operation first filling high heat capacity liquid in LED housing, expanding for preventing heated liquid and bursting housing, reserving cavity during filling high heat capacity liquid in housing, in this cavity, have air; In housing after filling 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, usually puts into nylon wire in advance in the housing, insert again in housing, by nylon wire and the gap that formed between housing and light emitting host, air is overflowed, light emitting host can 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 its cost of labor of liquid LED manufacture craft is higher, and put into nylon wire in advance in the housing, light emitting host inserts in housing again, then extracts nylon wire out, and technique is comparatively complicated, increase cost of manufacture; Meanwhile, still have air in housing hollow, the heat that light emitting host luminescence produces makes gas expansion, 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
The object of the present invention is to provide a kind of manufacture craft of liquid LED, the liquid LED cooling effect that this technique makes is better, make the power of liquid LED to reach 15W, and service life is longer.
For reaching above-mentioned purpose, solution of the present invention is:
A manufacture craft for liquid LED, comprises the following steps:
One, filling 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 into confined space, and this confined space is vacuumized, make the reserved cavity of housing be in vacuum state, then light emitting host is inserted in housing;
Four, light emitting host is inserted the junction welded seal after housing, complete the making of liquid LED.
Further, before light emitting host being inserted in housing, also comprise light emitting host aligning step.
Further, after light emitting host being inserted in housing, also comprise and open confined space and opening encapsulation step.
Further, light emitting host being inserted the junction welded seal after housing is laser weld.
After adopting such scheme, the liquid LED made by manufacture craft of the present invention, cavity due to filling radiator liquid housing is vacuum state, therefore, during radiator liquid expanded by heating, the housing hollow pressure of vacuum state no longer increases, thus make radiator liquid temperature be unlikely to rapid rising, the power of liquid LED is made to reach 15W, meanwhile, housing hollow pressure is less, less to the internal stress of housing, make the service life of liquid LED longer, the sealing effectiveness of housing and light emitting host is better.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Consult shown in Fig. 1 to Fig. 5, the manufacture craft of a kind of liquid LED that the present invention discloses, comprises the following steps:
One, filling radiator liquid 11 in the housing 1 of LED, this radiator liquid 1 is generally conduction oil, the various high heat capacity liquid of paraffin wet goods, and reserves cavity 12 within the case 1, as shown in Figure 1.
Two, the light emitting host 2 of LED is placed in housing, leaves gap between light emitting host 2 and housing 1, now, light emitting host 2 does not insert in housing 1 completely, vacuumizes to facilitate.This light emitting host 2 is generally on heating column and arranges LED chip, and 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 into confined space 3, and this confined space 3 is vacuumized, make the reserved cavity 12 of housing 1 be in vacuum state, then light emitting host 2 is inserted in housing 1, now, light emitting host 2 and housing 1 are interference fit, light emitting host 2 and housing 1 junction are comparatively sealed, as shown in Figure 3.
Can not offset when inserting in housing 1 for making light emitting host 2, improving and inserting accuracy rate, before light emitting host 2 is inserted in housing 1, light emitting host 2 can being 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, complete the making of liquid LED, as shown in Figure 5.Described welded seal is generally laser weld, pollution-free, and welded seal effect is better.
For making welding effect better, and being convenient to automation mechanized operation, after inserting in housing 1 by light emitting host 2, confined space 3 and opening encapsulation can being opened.
The liquid LED that the present invention makes, because the cavity 12 of filling 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, thus makes radiator liquid 11 temperature be unlikely to rapid rising, the power of liquid LED is made to reach 15W, meanwhile, housing 1 cavity 12 pressure is less, less to the internal stress of housing 1, make the service life of liquid LED longer, housing 1 is better with the sealing effectiveness of light emitting host 2.
The foregoing is only the preferred embodiments of the present invention, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
