Abstract
The utility model provides a heat dissipation structure of a high-power LED module. The technical aim of the utility model is to provide the heat dissipation structure of the high-power LED module having a good heat dissipation effect and a long service lifetime. The heat dissipation structure of the high-power LED module includes an aluminum substrate provided with an LED lighting chip. A wide-angle lens is arranged above the LED lighting chip. A layer of polyamide hot melt adhesive is arranged above the aluminum substrate and outside the wide-angle lens. The bottom part of the aluminum substrates contacts with air. The heat dissipation structure of the high-power LED module provided by the utility model has the good heat dissipation effect, a long service lifetime, and good dustproof and waterproof effects. The heat dissipation structure of the high-power LED module is suitable for applying in a daily lighting area.
Description
Technical field
The utility model relates to a kind of structure of great power LED module, in particular, relates to a kind of radiator structure of great power LED module.
Background technology
High-power module in the prior art; All be with pcb board or aluminium base that a slice is posted high-powered LED lamp adopt full Shooting Technique with whole pcb board and above electronic component except that the lamp pearl, comprise that resistance covers, make PCB and top electronic component have water resistance; But owing to adopted high-powered LED lamp; The temperature that entire module produces can be very high, and then temperature can not very fast being discharged, so high-power module radiating effect on the market is not resolved.Great power LED module of the prior art exists the bad technological deficiency of heat radiation, becomes those skilled in the art's technical problem anxious to be solved.
Summary of the invention
The technical purpose of the utility model is to overcome in the prior art, and it is bad and then influence the technical problem in service life that the great power LED module exists heat radiation, and the radiator structure of the great power LED module of a kind of good heat dissipation effect and long service life is provided.
For realizing above technical purpose, the technical scheme of the utility model is:
The radiator structure of great power LED module includes aluminium base, and said aluminium base is provided with the LED luminescent wafer; Said LED luminescent wafer top is provided with wide-angle lens, the said aluminium base top and the wide-angle lens outside; Be provided with one deck polyamide hot, the bottom contact atmosphere of aluminium base.
Further, around the said aluminium base, be provided with the oblique angle.
In the utility model is used; Be provided with the oblique angle of same angle around the aluminium base; In injection moulding, the bottom of aluminium base is exposed in the air then, then the heat that produces of module just can directly propagate in the air through aluminium base, plays good heat-radiation effect.
The useful technique effect of the utility model is: good heat dissipation effect, and long service life, and the dustproof and waterproof effect is good.Adopt the wide-angle lens of customization, make hot spot more even, light mixing distance is littler, thereby uses powerful module in the application of reality, to bring into play its advantage: do not reduce illuminating effect when can reduce module quantity significantly; And wide-angle lens also is closely buckled in LED luminescent wafer top, and injection moulding has then promptly been carried out good protection to the LED luminescent wafer and played good waterproof effect again on shell.
Description of drawings
Fig. 1 is the plan structure sketch map of an embodiment of the utility model.
Fig. 2 is the sectional structure sketch map of an embodiment of the utility model.
The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2, specify the specific embodiment of the utility model, but claim is not done any qualification.
In the radiator structure of the utility model great power LED module, include aluminium base 4; Said aluminium base 4 is provided with LED luminescent wafer 2; Said LED luminescent wafer 2 tops are provided with wide-angle lens 3, said aluminium base 4 tops and wide-angle lens 3 outsides; Be provided with one deck polyamide hot 1, the bottom contact atmosphere of aluminium base 4.Around the said aluminium base 4, be provided with oblique angle 5.
In the utility model is used; Be provided with the oblique angle 5 of same angle around the aluminium base 4; In injection moulding, polyamide hot is not wrapped up in the bottom of aluminium base 4 then; Expose in the air, then the heat of module generation just can directly propagate in the air through aluminium base 4, plays good heat-radiation effect.
Good and the long service life of the utility model radiating effect is the not only practical but also novel technological improvement of one of this area.
Claims (2)
1. the radiator structure of great power LED module; It is characterized in that: include aluminium base, said aluminium base is provided with the LED luminescent wafer, said LED luminescent wafer top; Be provided with wide-angle lens; The said aluminium base top and the wide-angle lens outside are provided with one deck polyamide hot, the bottom contact atmosphere of aluminium base.
2. the radiator structure of great power LED module according to claim 1 is characterized in that: around the said aluminium base, be provided with the oblique angle.
