The present invention discloses a miniaturized LED lighting module for an LED headlight assembly. A light guide element is provided at a light emitting surface of an LED element to gather the light of the LED element and then emit it from the light emitting side. The light emitting side of the light guide element is provided or formed with a shading plate in accordance with the light type specified in the headlight regulations, so that part of the light emitted from the light emitting side is blocked, so as to correct the light type of the light emitting light to meet the light type specified in the headlight regulations. After that, this light type is projected outward through a lens. In this way, the light type projected by the LED lighting module of the present invention can meet the regulations and can be directly used as an LED headlight assembly.
Description
Technical field
The present invention is about a kind of LED head lamp group, especially refer to the miniaturization LED illumination module that a kind of LED of confession head lamp group is used, this LED illumination module is a built-in shade directly, makes its bright dipping light type meet the light type standard of headlight, and can directly use as the head lamp illumination module.
Background technology
As shown in Figure 6, structure for the previous a kind of projection-type LED illumination module that proposes of applicant, so-called projection-type is that LED element 51 is arranged at the LED illumination module that one side is answered a dome-type reflector 50 inner faces, make the illuminating source of this LED element 51 light be concentrated ejaculation forward by this reflector 50, in bright dipping place of this dome-type reflector 50 matte 52 that meets headstock lamplight type scope is set again, to revise the bright dipping light type of this LED, the light type that will meet the rules standard after will revising again is projected to lens 53, by lens 53 with ray cast afield.
Owing to is a trend with the LED element as headlight, and each tame car light factory does one's utmost to research and develop the best lamp group factory that buys car in installments invariably and uses at present.For design difference in functionality car light (lamp far away, low beam, fog lamp) the most normal use nothing more than being to adopt difform matte, reach simple modifications light type to meet the regulation of car light rules.
Yet, design as this LED illumination module, though can successfully launch the light type that meets the rules standard, but with present LED element luminosity, maximum probably is about the brightness of 150-200 lumen at present, if will reach 1000 above lumens of present halogen vehicle lamp, then approximately needs the LED illumination module more than 5, therefore, the present car light group that all needs some to rearrange with the headlight of LED illumination module composition.Hence one can see that, and the design of dwindling the LED illumination module has its necessity.
See also shown in Fig. 7,8, be Fig. 1,2 of EP 1 487 025 A2 of European Union number " led light source that headlight for vehicle is used " patent disclosure case, promptly disclose a kind of direct change LED element 1 inner encapsulating structure, and make a kind of light source that meets headlight bright dipping light type rules that has, it consists predominantly of:
One pedestal 3a is formed with a bug hole on it;
One lead frame 3b is located at the side of this pedestal 3a;
One luminescence chip 2 is fixed in the bug hole of this pedestal 3a, and is electrically connected with lead frame 3b via lead 4;
One phosphor body 5 is filled in this bug hole, to cover this luminescence chip 2;
Colloid 9 covers this pedestal 3a upper surface, and with phosphor body 5 and luminescence chip 2 involutions wherein;
One matte 7 is covered on this colloid 9.
The open case of above-mentioned foreign country mainly is to be bonded in this LED element 1 in order to the matte 7 of revising the light source light type one, makes to have a matte in this LED element 1 directly, and makes its light type that goes out radiant directly meet rules and regulations, and a head lamp of buying car in installments uses.Though this open case of foreign country is directly transformed the structure of LED element, to reach the light type that meets headlight, has relatively also increased the degree of difficulty of LED element encapsulation procedure, need bear LED element yield and reduce, the risk that cost improves.
Summary of the invention
Main goal of the invention of the present invention provides a kind of miniaturization LED illumination module for the use of LED car light group, and does not need to change the processing procedure of LED element, can meet the needs of present headlight size.
Desire to reach the employed major technique means of above-mentioned purpose and provide a kind of miniaturization LED illumination module, include:
One LED element is arranged on the substrate;
One light-guide device, be arranged on the preceding exiting surface of this LED element, collecting the light guide of this LED element, it is with respect near the bright dipping side setting of this LED element exiting surface or form a light shielding part, this LED element bright dipping light type is modified to the light type of symbol headlight rules standard;
One lens are arranged at this light-guide device bright dipping side front end, so that light is outwards throwed.
According to such scheme, above-mentioned miniaturization LED illumination module of the present invention mainly is provided with a light-guide device in bright dipping place of LED element, after the light of LED element is gathered, forms a light shielding part in its exiting surface, the moulding according to the headstock lamplight type of this light shielding part.Therefore, this light-guide device promptly is a light type that meets the headlight rules and regulations through the light that lens projects goes out, can directly be used as LED headlight group, and its volume is littler compared to projection-type LED car light, and, and do not have the problem that yield is low, cost is high because do not change the structure process of LED element yet.
