The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
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 switched baffle plate 9 with distance-light and are connected, 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 utility model, the speculum on described light cup 4 is ellipsoidal mirror.
Wherein, lens unit comprises the light cup cover 3 being 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 utility model 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, is more finally transmitted on lens 1 via hollow out fixed head 10, and scioptics 1 refraction spreads out.
The utility model moves up and down by the drive distance-light switching baffle plate 9 of push-pull device at fixed 8, thereby makes distance-light switch the relative displacement up and down that baffle plate 9 produces 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 being reflected by the speculum of light cup 4 switches the optical cross section outgoing after baffle plate 9 via hollow out fixed head 10 and distance-light, 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 to switch baffle plate 9 and produce downward displacement, now outgoing be distance light.
Described wick 5 is LED wicks.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.Compare with xenon headlight with traditional halogen regenerative-cycle headlamp, the utlity model 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, are the excellent selections of replacing existing automobile headlamp light source assembly.
Due to the direct effect of radiator fan 7, make the heat region that LED wick produces produce forced air convection, the heat of thermal source central area spreads to outside through radiator fan 7 fast with the form of hot-air.Meanwhile, make radiator fan 7 belows and ambient air generation hot pressing poor, thereby accelerated the air motion of radiator fan 7 periphery 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 utility model, 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 in this way, 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 being timely and effectively transmitted on light cup 4 is fallen.
In the utility model, 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 is to shed with the mode of light cup 4 peripheral air generation cross-ventilation heat radiations.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 around simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
