Embodiment 1

In the present embodiment, detailed illustration will be carried out to LED module 102, substrate 105.

The LED module 102 is exactly that LED (light emitting diode) is encapsulated again together as necessarily regularly arranged, is added The product of some water-proofing treatments composition, that is, LED module.LED module 102 in the utility model shines core including LED Piece and corresponding integrated circuit, the LED module 102 fitting are installed on substrate 105.Specifically, as shown in Figure 6, Figure 7, LED moulds Block 102 is arranged on the both sides of substrate 105.

In order to reach the requirement that automotive LED headlamp 100 uses dipped beam and distance light, the both sides of substrate can set LED Module 102, and coordinate with power adapter circuit and realize distance-light checker function.In order to reach dipped beam standard light type, As shown in fig. 7, two groups of LED modules 102 can be set in 105 homonymy of substrate.

Substrate 105 in the utility model plays the role of fixed LED module 102, it can be bonded with LED module 102 Installation, in this way, substrate 105 is exactly removably connected to reflector 103 and LED module 102.It is easily understood that should When substrate 105 is using metal, it can be welded with reflector.

It should be noted that in order to ensure adapter that the electric wire needed for LED module 102 can connect to behind housing 101, Hollow pipe 10211 can be set, which passes through and sequentially pass through housing 101, reflector 103 and be deep into substrate 105 In, which protrudes from housing 101, and the other end is deep on substrate 105, the LED moulds on such substrate 105 Block 102 and temperature measuring equipment 1021 can lead to electric wire outside housing 101, in order to which power supply adaptor connects.

The substrate 105 of the utility model is equipped with light modulation baffle 108, is cut for cooperatively forming dipped beam light and shade with reflector 103 Only line.

Embodiment 2

In the present embodiment, detailed illustration will be carried out to reflector 103, housing 101.

Reflector 103 in the utility model is used to reflect and focus on light, which is connected with housing 101. Connection between reflector 103 and housing 101 is a kind of sealed connection, specifically, the edge part of reflector 103 and housing 101 It is to be tightly connected, this sealed connection can be connected by the first sealing ring.

In addition, it is at this time, reflective as shown in figure 4, connection can be integrally formed between the reflector 103 and housing 101 Without hollow structure among bowl 103 and housing 101.

103 edge of reflector in the utility model is circumferentially with LED lamp bead 1031, which is used as signal Lamp is used.

It should be noted that can be fastener connection between reflector 103 and housing 101, can such as screw be used to connect, Can also be by the way of being glued.In a particular embodiment, 101 edge of housing and 103 edge of reflector are set first Sealing ring is simultaneously linked together by way of splicing.

The reflector 103 of the utility model is made of metal, and can such as use aluminium, copper, which can ensure The needs of reflected light, it can use aluminium, copper etc. to be made, its reflective surface can be made into minute surface；On the other hand, the metal reflective bowl Good heat dissipation effect.

It should be noted that when 105 both sides of substrate are both provided with LED module 102, reflector 103 divides for Part I And Part II.At this time, the surface of the Part I and the Part II is more curved surfaces.Wherein Part I, for example, It can be upper part, for installing dipped beam LED module, the light source of dipped beam can be formed.Wherein Part II, for example, can be lower part, For installing distance light LED module, the light source of distance light can be formed.

As shown in Figure 1, shown in Figure 5, the heat sink 107 on housing 101 is used to radiate to the automotive LED headlamp 100, the heat dissipation Piece 107 is mainly outwards radiated using the mode of heat radiation.Therefore the shape of the heat sink 107 and material are for the heat sink 107 heat dissipation effect has significant impact.

Specifically, which can be multiple fins, and fin can play good heat dissipation effect.The heat sink 107 It may be configured as spiral fin.Spiral fin improves the heat dissipation area of fin, and heat dissipation effect is good.Heat sink 107 It is the fin-like thermal component made of thin material.After heat sink 107 absorbs heat, with the form of convection current by heat produced Falling, heat dissipation area is mainly determined that surface area is bigger by the size of the surface area of heat sink 107 during heat loss through convection, Heat dissipation effect is better；Surface area is smaller, and heat dissipation effect is poorer.In the radiator of application fin, the means that generally use Mainly include：Increase the quantity of radiating fin, increase by two kinds of the length of radiating fin, its data embodied is exactly " thick high Than ", i.e., the ratio of fin thickness and height, the smaller fin for meaning unit volume of this value can do closeer, quantity More, the surface area effectively to radiate is bigger, and heat dissipation performance is also better.

Above-mentioned heat sink 107 can use the good heat sink material of heat dissipation effect.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5,101 edge of housing of the utility model is equipped with ventilation hole 1011, is used for Improve the heat dissipation effect of heat sink 107.Specifically, when there is wind by ventilation hole 1011, the heat on 107 surface of heat sink can be accelerated Convection current, so as to play good heat dissipation effect.When automobile is in enforcement state, which has convection current, which adds The speed heat dissipation of heat sink 107 and housing 101, substantially improves the heat dissipation effect of the automotive LED headlamp 100.

As shown in Figure 8, Figure 9, connecting portion 1012 can be the otic placode of any shape and different rigging positions.The connecting portion 1012 Used for installing connection, which is a kind of mounting structure, its function is in order to by 100 groups of this automotive LED headlamp Be attached in vehicle lamp assembly, and can upper and lower, left and right adjust light position.The connecting portion 1012 can be the ear of any shape Plate.

Preferably, which also has indicative function, for example, in fig. 8, upper button point descends button obtuse into arrow shaped, it is intended that Installation site is to prevent reverse above and below instruction

Wind pressure sensing device further 113 in the utility model is electrically connected with the LED module 102.The wind pressure sensing device further 113 Equivalent to one recloser, it is arranged near ventilation hole 1011, can sense the size of wind pressure to adjust LED module 102 power, for example, when wind pressure is small, can reduce the power of LED module 102, specially using 1/2 luminous core of LED module Piece, reduces the caloric value of heat source, plays the role of overheat protector.
