Abstract

The invention discloses a punching, light-distributing and heat-radiating integrated LED light source module which is composed of a punching grid radiator, an LED light source, a light-distributing lens and a lens fixed ring, wherein the heat conductive surface of the LED light source is fixedly arranged in a mode of being closely attached to the mounting surface of the heat transfer substrate of the punching grid radiator; the light-distributing lens is fixedly arranged on the bright dipping surface of the LED light source through the lens fixed ring; seal treatment is carried out between the light-distributing lens and the heat transfer substrate of the radiator; and a closed light source cavity is formed between the light-distributing lens and the heat transfer substrate of the radiator, and the LED light source is disposed in the light source cavity exactly. The LED light source module of the invention has bright dipping, light distributing and heat radiating integrated design to achieve the optimal configuration and the optimal effect of the three functions and achieve different power and requirements through different combination.

Description

A kind of punching, light-distributing and heat-radiating integrated LED light source module

Technical field

The present invention relates to a kind of led light source, definite a kind of punching, light-distributing and heat-radiating integrated LED light source module of saying so.

Background technology

Advancing by leaps and bounds of LED illumination, market capacity expands rapidly, just like a raging fire the carrying out of green illumination illumination revolution, mostly technical force is limited but owing to downstream application producer, also unable input substantial contribution is used for basis research and development, so the luminous intensity distribution of LED application luminaire, not solution of heat radiation two big technical barriers is grasped by most LED light fixture factory to saving your breath not, they just simply imitate and piece together, and therefore the light fixture of being produced does not reach best of breed.

Summary of the invention

For addressing the above problem, the invention provides a kind of a kind of punching, light-distributing and heat-radiating integrated LED light source module that led light source, radiator and light-distribution lens are integrated in one.

Technical scheme of the present invention is as follows:

A kind of punching, light-distributing and heat-radiating integrated LED light source module, by perforation grid radiator, led light source, light-distribution lens and lens retainer ring constitute, the led light source thermal conductive surface is close to the fixed installation of perforation grid radiator heat transfer substrate installed surface, attach heat-conducting cream fat between led light source thermal conductive surface and radiator heat transfer substrate installed surface to reduce thermal resistance, light-distribution lens is fixedly installed in the led light source exiting surface by the lens retainer ring, add the sealing gasket encapsulation process between light-distribution lens and radiator heat transfer substrate, so form airtight light-source chamber between light-distribution lens and radiator heat transfer substrate, led light source just falls within this light-source chamber to guarantee that led light source is in the confined space of water proof and dust proof.

Described radiator is made by the contour heat conduction alloy material of copper, aluminium or magnesium, comprise fin and heat transfer substrate, fin is distributed in heat transfer substrate periphery and upper surface, reserve one side led light source and light-distribution lens are installed, the interlaced formation perforation of periphery fin is latticed, be designed to opening between each fin, heat transfer substrate upper surface fin need not to be arranged to staggered-mesh the dust stratification laying dust influence heat radiation in order to avoid form the dead band.

Described led light source is that LED package forms, and comprises light-emitting area and radiating surface.

Described light-distribution lens is that high permeability glass or resin are made, and is made of the plane of incidence and exiting surface, and the plane of incidence and exiting surface are free form surface, and light-distribution lens is the encirclement entity of two curved surfaces, and the entity periphery is provided with wing ring and cooperates installation with the lens retainer ring.

Perforate in the middle of the described lens retainer ring, perforate cooperates with the lens exiting surface, and periphery is established and radiator heat transfer substrate fixed connecting part.

Described fin can be plane or curved surface, links to each other with heat transfer substrate as far as possible for strengthening heat transfer heat conductivility fin, and fin can be by connecting the heat transfer substrate end by nearly attenuate simultaneously.

Described heat transfer substrate is the high-thermal conductive metal plate, and it simultaneously is an installed surface, and installed surface is provided with necessary installing hole in order to install and fix led light source and lens retainer ring.

Good effect of the present invention: this light source module is integrated in one luminous luminous intensity distribution heat radiation, downstream producer does not need too dark theoretical foundation and professional standards just can produce qualified light fixture product, its radiator has used aerodynamics and thermodynamic principles to design the latticed radiator of perforation, not only effectively promote radiating effect, and effectively dustproof sand prevention, light-distribution lens is designed to meet lighting requirements such as road, tunnel, square and view as required, meets the needs of various occasions.

The specific embodiment

As shown in Figure 1, perforation grid radiator (1) is made by the contour heat conduction alloy material of copper, aluminium or magnesium, comprise heat transfer substrate (11) and fin (12), fin is distributed in heat transfer substrate periphery and upper surface, reserve one side led light source and light-distribution lens are installed, the interlaced formation perforation of periphery fin is latticed, is designed to opening (13) between each fin, and heat transfer substrate upper surface fin need not to be arranged to staggered-mesh the dust stratification laying dust influence heat radiation in order to avoid form the dead band.

Heat transfer substrate (11) is the high-thermal conductive metal plate, and it simultaneously is an installed surface, and installed surface is provided with necessary installing hole in order to install and fix led light source and lens retainer ring.

Fin (12) can be plane or curved surface, links to each other with heat transfer substrate as far as possible for strengthening heat transfer heat conductivility fin, and fin can be by connecting the heat transfer substrate end by nearly attenuate simultaneously.

Led light source (2) comprises light-emitting area and radiating surface for LED package forms.

Light-distribution lens (3) is made for high permeability glass or resin, is made of the plane of incidence and exiting surface, and the plane of incidence and exiting surface are free form surface, and light-distribution lens is the encirclement entity of two curved surfaces, and the entity periphery is provided with wing ring and cooperates installation with the lens retainer ring.

As shown in Figure 2, lens retainer ring (4) is generally by compression moldings such as metal or plastics, perforate in the middle of it, and perforate cooperates with the lens exiting surface, and periphery is established and radiator heat transfer substrate fixed connecting part.

As Fig. 3, shown in 4, a kind of punching, light-distributing and heat-radiating integrated LED light source module, by perforation grid radiator (1), led light source (2), light-distribution lens (3) and lens retainer ring (4) constitute, the led light source thermal conductive surface is close to the fixed installation of perforation grid radiator heat transfer substrate installed surface, attach heat-conducting cream fat between led light source thermal conductive surface and radiator heat transfer substrate installed surface to reduce thermal resistance, light-distribution lens is fixedly installed in the led light source exiting surface by the lens retainer ring, add the sealing gasket encapsulation process between light-distribution lens and radiator heat transfer substrate, so form airtight light-source chamber between light-distribution lens and radiator heat transfer substrate, led light source just falls within this light-source chamber to guarantee that led light source is in the confined space of water proof and dust proof.
