Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority of Taiwanese Patent
Application No. 106126564, filed on Aug. 7, 2017.
FIELD
[0002] The disclosure relates to a headlight, and more particularly
to a headlight that can be configured as a high beam, a low beam,
or a turn signal of a vehicle.
BACKGROUND
[0003] A conventional headlight is adapted for use in a vehicle,
and includes a shell, and a plurality of light emitting modules
disposed in the shell. Each of the light emitting modules can
independently emit a light beam. The light emitting modules
cooperatively form a high beam or a low beam. The orientation of
each of the light emitting modules may be required to be adjusted
for emitting the light beam at an output angle that is satisfied
with the regulations. However, since the light emitting modules are
separately mounted in the shell, when a user needs to adjust light
output angles of the light beams emitted from the light emitting
modules, he or she has to adjust the light emitting modules one by
one. In such a manner, the user requires to repeat such an
orientation adjustment for many times, thus resulting in a
time-consuming adjusting operation. In addition, since the
orientations of the light emitting modules are individually
adjusted, when the user adjusts the orientation of one of the light
emitting modules, the orientation of an adjacent one of the light
emitting modules which has been adjusted may be required to be
re-adjusted. As a result, the adjusting operation becomes quite
complicated.
SUMMARY
[0004] Therefore, the object of the disclosure is to provide a
headlight that light output angles of light beams emitted therefrom
can be conveniently and rapidly adjusted.
[0005] According to the disclosure, the headlight includes a shell
unit defining a mounting space that extends in a front-rear
direction, a mounting seat pivotally mounted in the mounting space,
and having a plurality of mounting portions, a plurality of light
emitting units respectively mounted to the mounting portions of the
mounting seat, and an adjusting unit including an adjusting member
that is mounted to the mounting seat, and that is operable for
adjusting the angular position of the mounting seat. Each of the
light emitting units includes a light emitting member, and a lens
disposed in front of the light emitting member for allowing a light
beam emitted from the light emitting member to pass
therethrough.

DETAILED DESCRIPTION
[0012] Before the disclosure is described in greater detail, it
should be noted that where considered appropriate, reference
numerals or terminal portions of reference numerals have been
repeated among the figures to indicate corresponding or analogous
elements, which may optionally have similar characteristics.
[0013] Referring to FIGS. 1 to 4, the first embodiment of a
headlight according to the disclosure is adapted for use in
transportation such as a vehicle, and includes a shell unit 1, a
mounting seat 2, a plurality of light emitting units 3, an
adjusting unit 4 and an ancillary light unit 5.
[0014] The shell unit 1 includes a shell 11 and a transparent light
output cover 12 cooperatively defining a mounting space 10 that
extends in a front-rear direction. The light output cover 12 is
disposed in front of the shell 11.
[0015] The mounting seat 2 is pivotally mounted in the mounting
space 10, and has a plurality of mounting portions 21 arranged in a
left-right direction, an adjusting portion 22, and a coupling
portion 23 pivotally coupled with the shell 11 of the shell unit 1.
The mounting portions 21, the adjusting portion 22 and the coupling
portion 23 are arranged in a top-bottom direction. In this
embodiment, the adjusting portion 22 is disposed above the mounting
portions 21, and the coupling portion 23 is disposed below the
mounting portions 21. Each of the mounting portions 21 has a
surrounding wall 211, and a mounting hole 210 surrounded by the
surrounding wall 211, and extending in the front-rear direction.
The adjusting portion 22 is formed with an adjusting hole 220
configured as a threaded hole. The coupling portion 23 is formed
with a coupling hole 230. A pivot rod (not shown) extends through
the coupling hole 230 to pivotally couple the coupling portion 23
of the mounting seat 2 with the shell 11 of the shell unit 1. It
should be noted that, when the coupling portion 23 is pivotally
coupled with the shell 11, the coupling portion 23 is slightly
rotatable relative to the shell 11.
[0016] The light emitting units 3 are respectively mounted to the
mounting portions 21 of the mounting seat 2. Each of the light
emitting units 3 is received in the mounting hole 210 of a
corresponding one of the mounting portions 21, and is surrounded by
the surrounding wall 211 of the corresponding one of the mounting
portions 21. Each of the light emitting units 3 includes a circuit
board 31, a light emitting member 32 electrically connected to the
circuit board 31, a receiving frame 33 surrounded by the
surrounding wall 211 of the corresponding one of the mounting
portions 21, a lens 34 disposed in front of the light emitting
member 32 for allowing a light beam which is emitted from the light
emitting member 32 to pass therethrough, a reflecting cover 35
disposed for reflecting the light beam which is emitted from the
light emitting member 32 toward the lens 34, and a heat dissipating
member 36. For each of the light emitting units 3, since the
reflecting cover 35 covers a top side and a rear side of the light
emitting member 32, the light beam emitted from the light emitting
member 32 is reflected forwardly so as to allow the light beam to
pass through the lens 34 and to be output from the light output
cover 12. The lens 34 and the reflecting cover 35 are respectively
disposed at a front side and a rear side of the receiving frame 33.
The dissipating member 36 has a base portion 361 extending into and
fixedly connected to the receiving frame 33, and a plurality of
heat dissipating fins 362 disposed behind the base portion 361. The
circuit board 31 is mounted onto a top surface of the base portion
361.
[0017] It should be noted that, in this embodiment, the number of
the light emitting units 3 is five, and the number of the mounting
portions 21 is also five. In other embodiments, the numbers of the
light emitting units 3 and the mounting portions 21 may be
varied.
[0018] The adjusting unit 4 includes an adjusting member 41 mounted
to the mounting seat 2, and is operable for adjusting the angular
position of the mounting seat 2, and a motor 42 electrically
connected to the adjusting member 41, and driving rotation of the
adjusting member 41. In this embodiment, the adjusting member 41 is
a screw threadedly extending through the adjusting hole 220 of the
adjusting portion 22. The adjusting member 41 is drivably rotatable
for driving rotation of the mounting seat 2 so as to change the
angular position of the mounting seat 2 (An imaginary line in FIG.
4 illustrates the angular position of the mounting seat 2 that has
been changed). In addition, since the light emitting units 3 are
mounted to the mounting seat 2, when the angular position of the
mounting seat 2 is changed, light output angles of light beams
emitted from the light emitting units 3 are also adjusted.
[0019] The ancillary light unit 5 is mounted in the mounting space
10, and is disposed at one side of the light emitting members 3.
The ancillary light unit 5 maybe configured as a daytime running
light (DRL), a turn signal, or an indicating light which can
increase functions of the disclosure.
[0020] When assembling the headlight, each of the light emitting
units 3 is first assembled as a module, and is mounted to the
corresponding one of the mounting portions 21 of the mounting seat
2. Next, each of the light emitting units 3 is mounted to the
corresponding one of the mounting portions 21 from a rear side of
the mounting hole 210, and is fixed to the surrounding wall 211
with a screw or an engaging manner. After the light emitting units
3 are mounted to the mounting seat 2, the motor 42 drives the
rotation of the adjusting member 41. Since the adjusting member 41
threadedly extends through the adjusting hole 220, the rotation of
the adjusting member 41 drives the mounting seat 2 to slightly
rotate so as to change the angular position of the mounting seat 2,
and so as to change the light output angles of the light beams
emitted from the light emitting units 3.
[0021] In use, the light emitting units 3 cooperatively form a
light with a certain function. For example, the light emitting
units 3 can cooperatively form a high beam, or can cooperatively
form a low beam, or can cooperatively form a light having both high
beam and low beam functions. One part of the light emitting units
that has both high beam and low beam function cooperatively form
the high beam, and the other part of the light emitting units 3
cooperatively form the low beam. When two headlights are
respectively disposed at left and right sides of the vehicle, for
each of the headlights, two of the light emitting units 3 which are
close to a central portion of the vehicle cooperatively form the
high beam, and the remaining three of the light emitting units 3
which are distal from the central portion of the vehicle
cooperatively form the low beam. With such disposition, the shape
of the light projected area, the brightness of the light beams
emitted from the light emitting units 3, and the light projecting
angle of the light beams emitted from the light emitting units 3
are satisfied with the regulations.
[0022] It should be noted that, in this embodiment, the adjusting
member 41 is electrically driven by the motor 42, and the motor 42
may be omitted in other embodiments, in which a user may manually
rotate the adjusting member 41 to adjust the light output angles of
the light beams.
[0023] In conclusion, with the disposition of the mounting seat 2
and with the cooperation between the mounting seat 2 and the light
emitting units 3, it is convenient and time-saving for the user to
assemble the light emitting units 3 to the mounting seat 2, and it
is also convenient and time-saving for the user to adjust the light
output angles of the light beams emitted from the light emitting
unit 3 by adjusting the angular position of the mounting seat
2.
[0024] As shown in FIG. 5, the second embodiment has a structure
similar to that of the first embodiment. The main difference
between this embodiment and the previous embodiment resides in the
number of the light emitting units 3. In this embodiment, the
headlight includes four light emitting units 3, two of the light
emitting units 3 which are close to the central portion of the
vehicle cooperatively form the high beam, and the remaining two of
the light emitting units 3 which are distal from the central
portion of the vehicle cooperatively form the low beam. Therefore,
the second embodiment has the same advantages as those of the first
embodiment.
[0025] It should be noted that, the headlight may include three
light emitting units 3 in other embodiments, two of the light
emitting units 3 which are close to the central portion of the
vehicle cooperatively forming the high beam, and the remaining one
of the light emitting units 3 which is distal from the central
portion of the vehicle forming the low beam.
[0026] In the description above, for the purposes of explanation,
numerous specific details have been set forth in order to provide a
thorough understanding of the embodiments. It will be apparent,
however, to one skilled in the art, that one or more other
embodiments maybe practiced without some of these specific details.
It should also be appreciated that reference throughout this
specification to "one embodiment," "an embodiment," an embodiment
with an indication of an ordinal number and so forth means that a
particular feature, structure, or characteristic may be included in
the practice of the disclosure. It should be further appreciated
that in the description, various features are sometimes grouped
together in a single embodiment, figure, or description thereof for
the purpose of streamlining the disclosure and aiding in the
understanding of various inventive aspects.
[0027] While the disclosure has been described in connection with
what are considered the exemplary embodiments, it is understood
that this disclosure is not limited to the disclosed embodiments
but is intended to cover various arrangements included within the
spirit and scope of the broadest interpretation so as to encompass
all such modifications and equivalent arrangements.
