Lamp for vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp capable of forming different lamp images when the light source is on and off.

In general, the vehicle has various lamps having a lighting function for easily confirming an object located in the vicinity of the vehicle when driving at night and a signal function for notifying other vehicles or road users of the running state of the vehicle. The installation standards and specifications are stipulated by law.

For example, head lamps and fog lamps are mainly aimed at lighting functions, and turn signal lamps, tail lamps, brake lamps, and side markers are mainly used for signal functions.

Such automotive lamps are considered to be very important for the appearance of the vehicle in addition to functions for illumination and signaling. Particularly, in the case of a head lamp or a tail lamp, it is a major factor for determining the appearance of the vehicle at night.

Thus, as the performance of a vehicle lamp, as well as the appearance of a vehicle lamp, becomes more and more important, there is an increasing demand for a vehicle lamp having various appearance designs satisfying the requirements of the lighting function and the signal function.

To form a first lamp image and to cause a second lamp image to be formed by a shielded area other than the aperture hole 221 when the light source part 100 is turned off, Can be understood as being formed by the light forming the main beam pattern and the second ramp image being formed by the light forming the auxiliary beam pattern.

For this, in the embodiment of the present invention, the energy level of the light generated from the light source unit 100 is supplied to the bezel 220 to maintain the excited state of the energy level, and when the light source unit 100 is turned off, And a phosphorescent material that emits light while being lowered to a state of being low.

In the embodiment of the present invention, the case where the bezel 220 is made of a resin material doped with a phosphorescent material will be described by way of example, but the present invention is not limited thereto. The phosphorescent material may be in various forms such as sheet, ink, .

The lens unit 200 includes a first transmissive area A1 formed at the center of the lens 210 and a second transmissive area A2 formed around the second transmissive area A1, The portion L11 of the light generated from the light source unit 100 passes through the opening hole 221 when the light source unit 100 is turned on as shown in FIG. 5, The portion L12 may be blocked by the bezel 220 and the light L12 blocked by the bezel 220 may be substantially unnecessary as unnecessary light such as lowering the uniformity of brightness when forming the main beam pattern. Can be understood as light that is not used to form the beam pattern.

At this time, the light L11 passing through the aperture hole 221 can be transmitted to the outside through the first transmission area A1, and the light that is transmitted to the outside through the first transmission area A1 can be transmitted through the light- A main beam pattern suitable for the use of the lamp 1 for a vehicle is formed.

The light generated from the light source unit 100 passes through the aperture hole 221. In this case, the first lamp image I11 having the shape of the aperture hole 221 is formed in the lens unit 200 as shown in FIG. ).

Meanwhile, when the light source unit 100 is turned on, the phosphorescent material included in the bezel 220 is energized by the light generated from the light source unit 100 to maintain the excited state, and when the light source unit 100 is turned off 7, the light L13 is emitted while the energy level is lowered from the excited state to the ground state and the light L13 emitted from the bezel 220 is transmitted to the outside through the second transmission region A2, The second lamp image I12 is formed for a predetermined period of time after the second lamp image I12 is turned off and the time for forming the second lamp image I12 may vary according to the lighting time of the light source 100. [

Therefore, in the embodiment of the present invention, different lamp images are formed when the light source unit 100 is turned on and off, and the second lamp image I12 formed after the light source unit 100 is turned off, It is possible to improve the satisfaction of the driver.

In the embodiment of the present invention, the light emitted from the light source unit 100 is directly incident on the lens 210 through the aperture hole 221. However, the present invention is not limited to this, (Not shown) for guiding the light generated from the light source unit 100. The light guide may diffuse the light traveling through the aperture hole 221 so that light passing through the aperture hole 221 is totally Thereby making it possible to have a uniform brightness.

Meanwhile, in the embodiment of the present invention, the case where the bezel 220 is made of a resin material doped with a phosphor is exemplified. In this case, the beauty of the bezel 220 is deteriorated due to the color or the material of the bezel 220 The second lamp image I12 can be formed when the light source unit 100 is turned off because a half vapor deposition layer is formed so that a part of the light generated from the light source unit 100 can be transmitted to the bezel 220, Can be improved.

Although not shown in FIGS. 1 and 2, when a half mirror is formed on the bezel 220 as an example of the half deposition, a reflector (not shown) for reflecting light reflected by the half mirror back to the bezel 220 The bezel 220 can be prevented from deteriorating in aesthetics and light utilization efficiency can be improved.

In the above-described embodiment, a single opening hole 221 through which light for forming the main beam pattern passes is formed in the bezel 220. However, the present invention is not limited to this, and the main beam pattern and the auxiliary beam pattern A plurality of opening holes may be formed.

9 is a front view showing a bezel according to another embodiment of the present invention.

9, a bezel 220 according to another embodiment of the present invention includes a first aperture hole 222a through which light forming the main beam pattern passes, and at least one second aperture hole 222a through which auxiliary beam patterns are formed. And at least one second opening hole 222b may be formed around the first opening hole 222a.

The bezel 220 according to another embodiment of the present invention may be configured such that when the light source unit 100 is turned on, a part of the light L21 or L22 emitted from the light source unit 100 is divided into the first opening hole 222a and the at least one And the other part of the light L23 can be blocked by the bezel 220. In this case,

At this time, the light L22 passing through the light L21 passing through the first aperture hole 222a and the at least one second aperture hole 222b can form the first lamp image I21 as shown in FIG. And the first ramp image I21 may include a main beam pattern P1 by the first aperture hole 222a and an auxiliary beam pattern P2 by the at least one second aperture hole 222b.

12, the light L24 emitted from the shielded region other than the first opening hole 222a and the at least one second opening hole 222b as shown in FIG. To form a second ramp image I22.

In another embodiment of the present invention, the bezel 200 is formed with the first aperture hole 222a for forming the main beam pattern and at least one second aperture hole 222b for forming the auxiliary beam pattern, 100 are turned on, an auxiliary beam pattern for improving the appearance design can be formed together with the main beam pattern as the first lamp image I21, and when the light source unit 100 is turned off, The auxiliary beam pattern can be formed differently from the auxiliary beam pattern formed when the light source unit 100 is turned on, so that it is possible to form more various lamp images.
