The headlamp is not only a component part of the appearance of the automobile, but also main lighting equipment for driving under night or severe weather conditions, and has a vital effect on driving safety. At present, in order to reduce the cost of automobiles, most automobile manufacturers on the market adopt halogen lamps as light sources of headlamps, and special reflecting cups are arranged according to the light-emitting shapes of the halogen lamps to distribute light, so that glare to drivers of oncoming vehicles is avoided. However, since the halogen lamp has high power, low brightness and long life, the halogen lamp needs to be replaced in time to avoid potential safety hazard once light failure occurs. On the other hand, since the LED lamp has advantages such as long service life and high light extraction efficiency, when the halogen lamp needs to be replaced, it is a market trend to replace the halogen lamp with the LED lamp.
The existing halogen lamp comprises a bulb shell and a filament, wherein halogen elements or halides are filled in the bulb shell, and the bulb shell is generally in a symmetrical column shape, so that the halogen lamp emits light uniformly and the emergent light forms a column shape. However, the basic structure of the LED lamp is an electroluminescent semiconductor material, which emits light unevenly and has a hemispherical shape, so when the existing LED lamp is used to replace a halogen lamp, the LED lamp cannot be matched with a reflector cup of an original headlamp, and thus the problems of poor light emitting shape and poor light distribution effect of the headlamp are generated.

The technical scheme of the present invention is clearly and completely described below with reference to specific embodiments and drawings.
Example 1
As shown in fig. 1, a schematic structure of a headlamp according to embodiment 1 of the present invention is shown.
The headlamp 1 includes: a light distribution cover 10 and an LED substrate 14; the light distribution cover 10 is columnar and has a circular cross section, the inner wall of the light distribution cover is connected with two light modulation pieces 11, the two light modulation pieces 11 are axially symmetrically arranged by taking a perpendicular bisector of the light distribution cover 10, the two light modulation pieces 11 and the inner wall enclose two symmetrical first light distribution cavities 12, and the two first light distribution cavities 12 are communicated; the joint of any light modulation piece 11 and the inner wall of the light distribution cover 10 encloses a second light distribution cavity 13; the LED substrate 14 is disposed in the communication channel of the two first light distribution cavities 12, two LED chip sets 141 are disposed on the LED substrate 14, a first LED chip set of the two LED chip sets 141 is disposed opposite to a first light modulation member of the light modulation member 11, a second LED chip set of the two LED chip sets 141 is disposed opposite to a second light modulation member of the light modulation member 11, and any LED chip set 141 includes at least one LED chip.
When the two LED chip sets 141 on the LED substrate 14 emit light, the light emitted from the front surface of the LED chip set 141 has a larger light intensity, and the light emitted from both sides of the LED chip set 141 has a smaller light intensity. Since the LED chip set 141 is opposite to the light modulation member 11, the light emitted from the front surface of the LED chip set 141 is incident to the light modulation member 11, the light modulation member 11 adjusts the light path of the incident light, so as to reduce the light density of the incident light and uniformly transmit out of the light distribution cover 10; the light emitted from the two sides of the LED chip set 141 is incident into the first light distribution cavity 12, and the first light distribution cavity 12 distributes the light therein, so that the light in the first light distribution cavity 12 is uniformly transmitted out of the light distribution cover 10. In addition, the second light distribution cavity 13 is formed by surrounding the connection part of the light adjusting piece 11 and the light distribution cover 10, and light transmitted to the second light distribution cavity 13 can be distributed, so that light in the second light distribution cavity 13 can be uniformly transmitted out of the light distribution cover 10. Therefore, after the light emitted by the two LED chip sets 141 in the head lamp 1 is distributed by the light distribution cover 10, the emergent light with uniformly distributed light rays and columnar light shape is obtained, the emergent light shape of the head lamp 1 is consistent with that of the halogen lamp, the head lamp 1 can completely replace the traditional halogen lamp to be matched with the original reflector cup, the service life of the head lamp 1 can be effectively prolonged, and the replacement cost of the head lamp 1 is saved.

Further, as shown in fig. 4, in order to improve the light-emitting efficiency of the headlamp 1, a reflective layer 151 is coated on the light-incident surface of the first light distribution prism 15 with an incident angle smaller than the critical angle of total reflection, so as to reflect the incident light, so that the reflected light can be totally emitted through the first light distribution prisms 15 with other non-coated reflective layers, and the utilization rate of the light emitted by the LED chipset 141 is improved; wherein the critical angle for full emission is used to indicate the critical angle at which full emission of incident light occurs.

3. The head lamp of claim 2, wherein the first light distribution prism comprises one or more of a triangular prism, a cylindrical prism, a tread prism, a horseshoe prism, a tile prism and a wedge prism, and the first light distribution prism is made of a high light transmittance material.
4. The head lamp of claim 2, wherein a light-reflecting layer is coated on a light-incident surface of the first light distribution prism having an incident angle smaller than a critical angle of total reflection to reflect incident light; wherein the critical angle for full emission is used to indicate the critical angle at which full emission of incident light occurs.
5. The headlamp of claim 1 wherein the cross section of the light distribution cover is circular or elliptical.
6. A head lamp module comprising the head lamp of any one of claims 1 to 5 and a mounting bracket; wherein,
the mounting frame comprises a supporting piece and a mounting seat connected with the supporting piece;
the LED substrate of the head lamp is fixed on the supporting piece, and the light distribution cover of the head lamp is sleeved on the mounting seat.
7. The head lamp module as recited in claim 6, further comprising:
the buckle is arranged at the bottom of the mounting seat so as to clamp the head lamp module into the reflecting cup;
the heat dissipation lamp body is connected with the bottom of the buckle to support the headlamp, and a fan is arranged in the heat dissipation lamp body;
and the cable penetrates through the heat dissipation lamp body, the buckle and the mounting seat and is connected with the LED substrate so as to supply power to the LED chip set.
8. The head lamp module of claim 6, wherein the edge of the inner wall of the light distribution cover is provided with a convex strip; the mounting seat is cylindrical, and a groove is formed in the edge of the outer wall of the mounting seat; the protruding strip is engaged with the groove to mount the headlamp.
