Description

Lamp for welcoming lights

The present invention relates to a luminaire, and more particularly to a luminaire for use in a vehicle.

The welcome light (also known as the ground light) used in automobiles is generally installed on the door or the rear view mirror. When the door is opened, the function is turned on and the image is projected on the ground, which not only produces unique dazzling image light and projected image, but also gets off at night. It also provides the function of illuminating the ground so that people who get on and off can see the ground without accidentally stepping on the dirt, puddles, or dangerous terrain on the ground.

Since the ground light will produce unique dazzling image light and projected image, if only a single image is projected, although the function of illuminating the ground can be achieved, it is difficult to meet the psychological needs of the driver for a long time.

Embodiments of the present invention provide a light fixture that can be disposed in a vehicle such as a car, including a light source and a fixed image light valve. The light source generates illumination light of a plurality of different regions; the fixed image light valve is disposed on the illumination path of the illumination light of the plurality of different regions, and has a fixed image of a plurality of different regions, respectively corresponding to the illumination light of the plurality of different regions, Converts illumination light into image light. A variety of projection images can be achieved by various embodiments.

Therefore, by using the illuminating device provided by the embodiment of the present invention, a plurality of projection images can be generated by combining various embodiments of the light source and the fixed image light valve, thereby making it possible to use relatively simple but effective parts in a small volume. Achieving a variety of projected images, not only provides the function of illuminating the ground, but also a variety of projected images make the people who watch it feel dazzling and amazed.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Embodiments of the present invention provide a luminaire that can be used in a vehicle, such as a door or a rear view mirror of a car to become the welcoming lamp or the illuminating lamp. The luminaire mainly comprises a light source and a fixed image light valve. The light source can generate illumination light of a plurality of different regions, and the fixed image light valve is disposed on the illumination path of the illumination light in a plurality of different regions, and has a fixed image of a plurality of different regions. Corresponding to illumination light of a plurality of different regions, the illumination light can be converted into image light. By combining the light source and the fixed image light valve, the converted image light can be irradiated on the ground or the surface of the object to form a plurality of projected images, and various embodiments can be described later.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of an embodiment of the present invention. When a plurality of light-emitting elements 1002 are included in the light source 10, for example, a plurality of LED lights are collectively packaged in one of the lamps 5. The illumination light 30 can be generated by the light-emitting elements 1002 to fix the image light. The valve 14 can be, for example, a slide. The illumination paths of each of the light-emitting elements 1002 respectively correspond to different fixed images 20, so when the illumination path of the illumination light 30 is generated by one of the light-emitting elements 1002, a corresponding fixed image 20 is converted. The projected image 2002 projected by the image light 32.

In an embodiment, the luminaire 5 further includes an outer frame 12 having an opening 1202. The illuminating element 1002 is disposed in the outer frame 12 and away from the opening 1202. The fixed image light valve 14 can be fixed in the outer frame 12 and located in the illuminating element. Between 1002 and opening 1202, the slide sheet has a plurality of fixed images 20a, 20b of different regions, and one of the plurality of fixed image 20 image lights 32 can be emitted from the opening 1202, thereby enabling a plurality of projected images 2002a, 2002b, 2002c. Projected.

As will be described in more detail with reference to Fig. 1, when only the light-emitting element 1002a is lit, the illumination path of the illumination light 30 generated by the light-emitting element 1002a becomes the image light 32 by the fixed image 20a, and the image light 32 projects the projected image 2002a. When only the light-emitting element 1002b is lit, the illumination path of the illumination light 30 generated by the light-emitting element 1002b becomes the image light 32 by the fixed image 20b, and the image light 32 projects the projected image 2002b. When the light-emitting element 1002a and the light-emitting element 1002b are simultaneously illuminated, the illumination light 30 passes through the fixed images 20a, 20b at the same time, and the transmitted image light 32 partially overlaps, thereby forming a partially overlapping projected image 2002c.

It should be noted that the illumination light 30 is the image light 32 after the image light valve 14 is fixed. However, in order to prevent the image light 32 from being excessively diverged, the projection lens 35 can be used to correct the optical path. FIG. 1 has two projection lenses 35, but The embodiment does not limit the image light 32 to the lamp 5 in a nearly parallel light manner, so that the formed projected image 2002 is more optimized.

Further, if the three projected images 2002a, 2002b, and 2002c are to be changed in different colors, another embodiment may enable the light-emitting elements 1002a and 1002b to generate light of different wavelength ranges, respectively, to illuminate a plurality of different regions. 30 has a different color. For example, when the light-emitting element 1002a generates light of a green wavelength range, the projected image 2002a corresponding to the light-emitting element 1002a alone is green, and the light-emitting element 1002b generates light of a red wavelength range, and the projected image 2002b corresponding to the light-emitting element 1002b alone is red. When the light-emitting element 1002a and the light-emitting element 1002b are used at the same time, the upper portion of the projected image 2002c is green, the lower portion is red, and the middle portion is yellow.

In addition, in another embodiment in which the three projected images 2002a, 2002b, and 2002c have different colors, a plurality of different colors of phosphor powder (not shown) may be coated on the fixed image light valve 14 to make the light source 10 illuminating light 30 generated in a plurality of different regions, after passing through the phosphor powder, exciting image light of different colors. As shown in FIG. 1, when the fixed image 20a is coated with the fluorescent powder that excites the green light when the illumination light 30 is penetrated, the projected image 2002a will be green, and the fixed image 20b is coated to cause the illumination light 30 to penetrate when the red light is excited. In the fluorescing powder, the projected image 2002b will be red, and both will be coated. When the illumination light 30 penetrates, the upper portion of the projected image 2002c will be green, the lower portion will be red, and the middle portion will be yellow.

Please refer to FIG. 2, which is a schematic diagram of another embodiment of the present invention in which a plurality of projected images 2002 are of different colors.

At this time, a plurality of different colors of phosphor powder (not shown) may be provided on the collecting lens 37, so that the illumination light 30 generated by the light source 10 in a plurality of different regions passes through the collecting lens 37 to generate different colors. 2, when the illumination path of the illumination light 30 generated by the light-emitting element 1002a is applied to the phosphor of the green light through the corresponding area of the condensing lens 37, the projected image 2002a will be green, and the illumination light generated by the light-emitting element 1002b will be illuminated. The illumination path of 30 is coated with the phosphor of the red light by the corresponding area of the concentrating lens 37, and the projected image 2002b will be red, and both will be coated. When the illumination light 30 penetrates, the upper part of the projected image 2002c will be Green, the lower section is red, and the middle section is yellow.
