Description
Technical field
The present invention relates to a kind of semiconductor element, particularly a kind of LED light source module.
Background technology
LED, as the efficient light emitting source of one, is applied to various field widely because having the various features such as environmental protection, power saving, life-span length.
In recent years, adopt LED light source in a large number in headstock illuminating lamp, its primary structure is the design of LED light source collocation light guide plate.This headlight LED light source is arranged on the side of light guide plate thus the light that LED light source is sent is coupled into light guide plate from light guide plate side.General light guide plate is very thin, and the light sent to enable LED light source is as far as possible all coupled into light guide plate and improves light utilization ratio, and make the luminous small volume of side entering type LED light source, its width must be less than the thickness of light guide plate.Further, mixed light region when entering light guide plate to make optically-coupled between each LED light source is shortened, and the spacing between each LED light source can not be excessive, causes LED light source to arrange too tight.The lamp bar substrate of design like this is too elongated and be unfavorable for the heat radiation of LED light source, add the particularity requirement to brightness of headlight, so generally need to select, luminous intensity is large, ultra-high brightness LED light source, the heat produced is more, adding general headlight is all arranged near car engine position, more be unfavorable for the heat radiation of LED light source, these factors comprehensive, if LED light source design is unreasonable in headlight, LED light source accelerated ageing because of poor heat radiation will be caused, easily cause the headlight life-span significantly to reduce.
Summary of the invention
In view of this, be necessary to design the LED light source module that a kind of luminous efficiency is high, heat dispersion is good.
A kind of LED light source module, comprise radiator, be arranged on the LED light source of radiator side and light guide plate spaced with LED light source, described LED light source comprises at least one LED, flexible light-conducting pipe is provided with between described LED light source and light guide plate, described flexible light-conducting pipe has light inlet, relative light-emitting window and the body be connected between light inlet and light-emitting window, described light inlet is coupled with corresponding LED light, described light-emitting window is coupled with light guide plate, the bore of described light inlet is equal to or greater than the external diameter on described LED bright dipping top, establish in it for LED bright dipping top is covered completely.
LED light source module of the present invention, by arranging the light pipe with flexible extendability between LED light source and light guide plate, light pipe and LED light source be corresponding coupling one to one, and described light pipe is according to the gap size arranged between LED light source and the relative position between light guide plate to LED light source can be corresponding bending with extend, and does not affect between light guide plate and LED light source and form good transmission line.So, the light-emitting area of LED light source can not be limited because of its thickness of light guide plate, make LED light source can be used in high-power flat type light source, also can not enter the excessive and arrangement pitch limited between LED light source in light guide plate back mixing light region because of LED light source coupling light.Therefore the LED light source module in the present invention not only has the bright dipping of high strength high efficiency, and has good heat dispersion.
Further describe the present invention in conjunction with specific embodiments with reference to the accompanying drawings.

Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
As shown in Figure 1, be the front view of LED light source module of the present invention.Described LED light source module comprises radiator 10, be arranged on LED light source 20, light guide plate 40 of radiator 10 side, be arranged on light pipe 30 between LED light source 20 and light guide plate 40.
With reference to figure 2, described radiator 10 is made up of the good material of heat dispersion or polymeric material.The substrate 102 that described radiator 10 comprises a lengthwise and the multiple fin 101 outwards protruded out from described substrate 102 bottom surface.These fin 101 intervals are arranged, for outwards distributing the heat that substrate 102 absorbs.
Described LED light source 20 is positioned at described substrate 102 end face relative with bottom surface.Described LED light source 20 is made up of the LED at multiple interval.The heat that these LED produce conducts to fin 101 through substrate 102 and distributes.
Simultaneously with reference to figure 3, described light guide plate 40 is positioned at the top of LED light source 20, its by reflectivity the high and material such as acrylic that is not extinction or PC make.Described light guide plate 40 in plate, comprise the incidence surface 401 at two ends, 402, the exiting surface 404 of the back side 403 and opposite back side.Light after incidence surface 401,402 enters light guide plate 40 after the reflection at the back side 403 by exiting surface 404 outgoing.Light guide plate 40 inside can arrange some light guiding points (not shown), to spread light, improves the uniformity from exiting surface 404 outgoing.
Simultaneously with reference to figure 2, light pipe 30 is arranged between LED light source 20 and light guide plate 40, and for the optically-coupled of LED light source 20 outgoing is entered light guide plate 40, it is made up of the flexible material of high reflectance.Described light pipe 30 in a tubular form, comprises body 31 and the light inlet 301 and the light-emitting window 302 that are arranged at body 31 two ends.Described light inlet 301 connects with the LED of LED light source 20, and light-emitting window 302 is connected with the incidence surface 401 of light guide plate 40.Described light inlet 301 flare, its bore starts to increase gradually from the one end be connected with body 31, its bore away from the outermost end of body 31 is equal with the external diameter on LED bright dipping top or be slightly greater than the external diameter on LED bright dipping top, establishes in it for being covered completely on the bright dipping top of LED.Diameter is identical everywhere for the body 31 of described light pipe 30, and described light-emitting window 302 diameter is identical with body 31 diameter.The emergent ray of LED light source 20 enters light guide plate 40 by the incidence surface 401 of light-emitting window 302 and light guide plate 40 after the light inlet 301 of light pipe 30 is coupled into light pipe 30.
