The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not paying under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of compound distance-light one light source assembly, comprise light cup 4, on light cup 4, lens unit is housed, substrate 6 is housed on light cup 4, fixing wick 5 on substrate 6, light cup 4 exiting surface one sides are equipped with hollow out fixed head 10, push-pull device at fixed 8 is equipped with in hollow out fixed head 10 belows, and push-pull device at fixed 8 tops are connected with distance-light switching baffle plate 9, and radiator fan 7 is equipped with in light cup 4 belows.The both sides of the edge, hollow out face below of hollow out fixed head 10 overlap with the both sides of the edge, exiting surface below of light cup 4.In the present invention, the speculum on described light cup 4 is ellipsoidal mirror.
Wherein, lens unit comprises the light cup cover 3 be connected with light cup 4, in the draw-in groove of light cup cover 3, lens 1 is installed, and aperture 2 is pressed on lens 1.Described push-pull device at fixed 8 is sliding electromagnet preferably.
The present invention passes through the external vehicle-mounted 12V battery of constant-current supply, thereby provides constant current driven wick 5 luminous.The light of 5 outgoing of wick, after the reflection of the ellipsoidal mirror of light cup 4, more finally is transmitted on lens 1 via hollow out fixed head 10, and scioptics 1 refraction spreads out.
The present invention moves up and down by the drive distance-light switching baffle plate 9 of push-pull device at fixed 8, thereby makes the up and down relative displacement of distance-light switching baffle plate 9 generations with respect to wick 5 horizontal planes, and then controls the exiting surface shape of light cup 4, thereby realizes the switching of distance-light.As shown in Figure 3, the light gone out by the mirror reflects of light cup 4 is via the optical cross section outgoing after hollow out fixed head 10 and distance-light switching baffle plate 9, then, via the refraction of lens 1, forms lower beam illumination on ground.As shown in Figure 4, push-pull device at fixed 8 moves downward, drive distance-light switching baffle plate 9 and produce downward displacement, now outgoing be distance light.
Described wick 5 is LED wicks.The LED wick, as light source, is a kind of green energy resource, has long-life, low-power consumption, high-color rendering, high light efficiency, starts without advantages such as time delay, green non-pollutions.With traditional halogen regenerative-cycle headlamp, with xenon headlight, compare, the present invention has that power consumption is lower, light output efficiency is higher, longer service life, security are higher, start without advantages such as time delay, green non-pollutions, is the excellent selection of replacing existing automobile headlamp light source assembly.
Due to the direct effect of radiator fan 7, the heat zone that makes the LED wick produce produces forced air convection, and the heat of thermal source central area spreads to outside through radiator fan 7 fast with the form of hot-air.Simultaneously, make radiator fan 7 belows and ambient air generation hot pressing poor, thereby accelerated the air motion of radiator fan 7 peripheral cold airs.
As preferably, the air-out plane of radiator fan 7 is parallel with substrate 6 bottom surfaces, and this design makes radiating effect better.
As shown in Figure 2, as improvement of the present invention, can fin 11 be set on light cup 4, between fin 11, form heat dissipation channel, light cup 4 also has heat sinking function like this.After adopting this mode, light cup 4 is integrated, and reflection and the two kinds of functions of dispelling the heat are integrated.Can make like this thermal conductance of wick 5 go out distance minimization, then produce forced convertion by radiator fan 7, the heat heat exchange timely and effectively be transmitted on light cup 4 is fallen.
In the present invention, described substrate 6 is preferably aluminium base, can also between substrate 6 and light cup 4, scribble heat-conducting layer, after adding heat-conducting layer, can further improve radiating effect.
The heat that wick 5 distributes is directly transferred on the contact-making surface of light cup 4 and substrate by substrate 6.Next heat is divided into two parts and distributes: a part sheds in thermal-radiating mode by light cup 4 surfaces; Remaining most heat sheds in the mode with the 4 peripheral air generation cross-ventilation heat radiations of light cup.Cold air forms convection current by fin 11, takes away heat.
The use of radiator fan 7 makes radiating efficiency improve 20%, effectively avoids wick 5 hot air reflow on every side simultaneously.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
