Abstract
The invention belongs to the field of lamps for vehicles, and in particular relates to an LED lighting lamp for a vehicle, wherein the LED lighting lamp is not provided with a second light distribution structure. The LED lighting lamp comprises a PCB (Printed Circuit Board), wherein a plurality of LED light-emitting sources are arranged on the PCB. The LED lighting lamp for the vehicle is characterized in that each LED light-emitting source comprises an LED bracket, wherein a bathtub-shaped reflection bowl is arranged on each LED bracket, an LED chip is arranged on each LED bracket and is positioned on the center of each reflection bowl, a resin matrix is packaged on the outer side of each LED bracket, and an LED lens is arranged on the upper surface of each resin matrix and is shaped as an arch bridge. Through improving the structures of the LED light-emitting sources, the light type change of the single LED light-emitting source is realized, and the arrangement shape of the LED light-emitting sources on the PCB is regulated according to positions of using the lamp so that the light types of the LED light-emitting sources are overlapped to meet the light distribution requirement of the lamp for the vehicle, thus the lamp for the vehicle can meet the requirement of the light distribution rule of the lamp for the vehicle without secondary light distribution, and the structure of the lamp for the vehicle is simplified.
Description
Technical field
The invention belongs to the automobile lamp field, particularly a kind of vapour automobile-used LED lighting that does not have the secondary light-distribution structure.
Background technology
Automobile lamp all has strict photometric standards, and the light that only depends on light source to send can not satisfy the needs of photometric standards, and it needs reflector cavity, luminous intensity distribution lampshade or add means such as Fresnel Lenses and change, control car light light shape.
LED has been widely used in automobile lamp as new light sources; Existing automobile lamp is aesthetic in appearance, complex structure, position are compact; Most Design of Luminaires personnel understand not dark to the LED characteristic, still come the design vehicle light fixture by traditional thinking, and secondary light-distribution gets half the result with twice the effort often.The LED replacement bulb, it forms module by many LED, because structure is special, mentality of designing is different from bulb, accomplish that desirable secondary light-distribution difficulty is higher, even the structure that has can't be accomplished secondary light-distribution.The LED luminous tube of existing market can not satisfy the luminous intensity distribution laws and regulations requirement of automobile lamp equally.
Summary of the invention
The present invention is directed to the problem that prior art exists; Through LED light emitting source structure is improved; Realized the light shape of single led light emitting source is changed, and adjusted the layout shape of LED light emitting source on pcb board, the light shape of a plurality of LED light emitting sources has been superposeed satisfy the light distribution requirements of automobile lamp according to the position difference that light fixture uses; Thereby realize that automobile lamp does not have the luminous intensity distribution laws and regulations requirement that secondary light-distribution also can satisfy automobile lamp; Simplify the structure of automobile lamp, reduced the production cost of automobile lamp, be convenient to design the automobile lamp of various different-styles.
The present invention realizes through following technical scheme:
Vapour automobile-used LED lighting, it comprises pcb board, described pcb board is provided with several LED light emitting sources; It is characterized in that: the light emitting source of described LED comprises led support, and led support is provided with bathtub shape reverberation bowl, and led support is provided with led chip; And led chip is positioned at the center of reverberation bowl; The outside of led support is packaged with resin matrix, and the resin matrix upper surface is provided with the LED lens, and described LED lens are the arch bridge shape.
The width of described LED lens is between 2.5mm～5mm, and height is between 2.4mm～4.6mm.
Described reverberation bowl adopts metal material to process, and the medial surface of reverberation bowl is coated with reflector layer.
In sum; The present invention is through changing the shape of reverberation bowl; Adjust light that led chip the sends light shape after through the reverberation bowl reflection, the inside of having realized the reflection cavity that is used for secondary light-distribution on the car light has been accomplished the LED light emitting source, we are also according to the requirement of luminous intensity distribution rules simultaneously; The width of adjustment LED lens is adjusted the shape of the light that the LED light emitting source sends; The light angle of flare of height adjustment LED light emitting source that simultaneously also can be through adjustment LED lens, according to the requirement of the luminous intensity distribution rules of automobile lamp, we can adjust the layout shape of LED light emitting source on pcb board; Simultaneously can also adjust the LED light emitting source, make the illumination capability of whole automobile lamp satisfy the light distribution requirements of automobile lamp with respect to the pcb board angle of inclination.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
To vapour automobile-used LED lighting shown in Figure 4, it comprises pcb board 1 like Fig. 1, and described pcb board 1 is provided with several LED light emitting sources 2; LED light emitting source 2 can adopt according to different arrangements on pcb board, is convenient to realize the diversified and personalized of vehicle light shape, and the light emitting source of described LED comprises led support; Led support is provided with bathtub shape reverberation bowl; Led support is provided with led chip, and led chip is positioned at the center of reverberation bowl, and the outside of led support is packaged with resin matrix; The resin matrix upper surface is provided with the LED lens; Described LED lens are the arch bridge shape, are equivalent to the reflection cavity of existing automobile lamp secondary light-distribution is set to the inside of LED light emitting source here through the reverberation bowl that is provided with, and have saved the reflection cavity of the bigger secondary light-distribution of complicacy and structure; Realized the simplification of automobile lamp structure; Reduced the production cost of automobile lamp, simultaneously the structure of reverberation bowl and LED lens has been improved, made the requirement that to satisfy automobile lamp luminous intensity distribution rules through the light shape after reverberation bowl and the change of LED lens.
The width of described LED lens is between 2.5mm～5mm; Height is between 2.4mm～4.6mm, and the height of LED lens is shown in L2 among Fig. 3, and the width of LED lens is shown in L1 among Fig. 4; The width of LED lens is 3mm in the present embodiment; Highly be 2.8mm, the distribution curve flux of the single led light emitting source of sampling above-mentioned parameter is as shown in Figure 5, on scheming, can know; Can the light shape of LED illuminating source be changed through LED light emitting source of the present invention, and can be met the requirement of automobile lamp luminous intensity distribution rules through the stack of a plurality of LED illuminating source light shapes.
