Light engine in a kind of LED light fixture

Technical field

This is novel relates to illumination and heat dissipation technology field, refers in particular to the light engine in a kind of LED light fixture.

Background technology

Along with the development of lighting engineering, various light fixtures are constantly weeded out the old and bring forth the new.The LED lighting has been widely applied to a lot of occasions with plurality of advantages such as its energy-saving and environmental protection, still, how LED is carried out the difficult point that better heat radiation becomes the LED lighting engineering.

Light engine in existing LED illuminating lamp is all that the LED and the lens module that are contained on aluminium base form, existing lens module is mostly to adopt lens are convexly equipped with structure on the outer surface of installing plate, this structure needs two parts to assemble, increased the cost of operation, and the lens arrangement of evagination affects the attractive in appearance of product; Having presented light engine again does not all have thermal convection holes, is unfavorable for the heat radiation of LED.

Summary of the invention

This novel purpose is exactly the light engine that provides for the deficiencies in the prior art part in a kind of LED light fixture.

For achieving the above object, this novel technical scheme is: the light engine in a kind of LED light fixture, include: module lens, aluminium base and several LED, the center that module lens is bottle-cover-shape and module lens has the module lens through hole of heat loss through convection, the printing opacity outer face of module lens is planar structure, and one-body molded in the lid shape inner chamber of module lens have several optical lenses; The center of aluminium base has the aluminium base through hole of heat loss through convection, and after aluminium base was assemblied on the opening of module lens, the aluminium base through hole was mutually corresponding with the optical lens through hole, and several LED on aluminium base are corresponding one by one with several optical lenses respectively.

One-body molded in described module lens lid shape inner chamber have several internal threaded columns, has screwed hole on aluminium base, aluminium base by screw locking in screwed hole and internal threaded column.

The cross section of described module lens is identical with size with the shape of described aluminium base.

The one-body molded surrounding that has several optical lenses to be evenly distributed on the module lens through hole in the lid shape inner chamber of described module lens.

The cross section of described module lens is any one or the multiple combination in circular, square, regular hexagon, octagon, ellipse, rhombus, trapezoidal, triangle.

Cross section the best of described module lens is circular.

Described module lens through hole and described aluminium base through hole are any one or the multiple combination in circular, square, regular hexagon, octagon, ellipse, rhombus, trapezoidal, triangle.

Described module lens through hole and described aluminium base through hole are best for circular.

At least 3 of the numbers of described optical lens.

The number of described optical lens is 6.

After adopting said structure, the module lens of the embodiment that this is novel is one-body molded, and the printing opacity outer face of module lens is planar structure, makes that product shape is attractive in appearance, bright dipping is even; And the aluminium base through hole is mutually corresponding with the optical lens through hole, make this new application possess the effect of heat loss through convection in the LED light fixture, greatly increased harmony and the radiating efficiency of heat radiation, the tropical island effect of avoiding hot-spot to produce.As from the foregoing, this is novel, and to have parts few, assemble simple, aesthetic in appearance, bright dipping evenly, the characteristics of energy heat loss through convection.

The specific embodiment

Embodiment below in conjunction with accompanying drawing 1-3 is described in further detail:

Light engine in a kind of LED light fixture in embodiment, include: module lens 10, aluminium base 20 and several LED30, the center that module lens 10 is bottle-cover-shape and module lens 10 has the module lens through hole 11 of heat loss through convection, the printing opacity outer face 12 of module lens 10 is planar structure, and one-body molded in the lid shape inner chamber of module lens 10 have several optical lenses 13; The center of aluminium base 20 has the aluminium base through hole 21 of heat loss through convection, after aluminium base 20 is assemblied on the opening of module lens 10, aluminium base through hole 21 is mutually corresponding with optical lens through hole 11, and several LED30 on aluminium base 20 are corresponding one by one with several optical lenses 13 respectively.

One-body molded in described module lens 10 lid shape inner chambers have several internal threaded columns 14, has screwed hole 22 on aluminium base 20, and aluminium base 20 is locked in screwed hole 22 and internal threaded column 14 by screw 40.

The cross section of described module lens 10 is identical with size with the shape of described aluminium base 20.

The one-body molded surrounding that has several optical lenses 13 to be evenly distributed on module lens through hole 11 in the lid shape inner chamber of described module lens 10.

Cross section the best of described module lens 10 is circular.

Described module lens through hole 11 and described aluminium base through hole 21 are best for circular.
