New description: [New technical field] The new type relates to lighting devices for decorative purposes, in particular to a lighting method and a method for producing decorative lighting. [Prior Art] In addition to lighting, lighting is also used for decoration. The current technique for decorating lights is to use light to illuminate the shaded cover • to allow light to pass through the shade and produce the same color as the shade. The color of the light, look at how many colors are on the lampshade. Another technique is to let light penetrate the colored filter to produce the same color as the filter. But this technology can only be used to produce a single color of light. [New content] # One of the technical aspects of the present invention is to provide a lighting device for generating lights of two colors or more. The lighting fixture comprises a dichroic filiter, a light emitting diode and a lampshade. The light emitting diode is configured to emit light to the dichroic filter, and the lamp cover surrounds the light emitting diode and the dichroic filter. This produces two or more different colors of light on the lampshade. Another aspect of the present invention is to provide a lighting fixture for generating lights of two or more colors. The lighting fixture comprises a dichroic filter, a light emitting diode and a projection screen. The light emitting diode is configured to emit light to the two-color 3 M380423 filter, and the projection screen is located on one side of the dichroic filter. This produces two or more different colors of light on the projection screen. Yet another technical aspect of the present invention is to provide a lighting fixture for producing a light above a color. The aforementioned lighting package is a dichroic filter, a light emitting diode and a lampshade. Wherein, the light emitting diode is used to emit light to the dichroic filter. The light in the preset wavelength band passes through the dichroic filter, and the light outside the preset wavelength band is refracted by the dichroic filter. The light passing through the dichroic filter and the light refracted by the dichroic filter are irradiated onto the lamp cover. Thereby two or more different colors of light are produced on the lampshade. [Embodiment] Please refer to Fig. 1 and Fig. 2, and Fig. 1 is a perspective view of a lighting fixture according to an embodiment of the present invention, and Fig. 2 is an exploded view of Fig. 1. In this embodiment, the lighting fixture includes a dichroic filter 100, a light emitting diode 200, and a light cover 300. The light emitting diode 200 is configured to emit light to the dichroic filter 100, and the lamp cover 300 surrounds the light emitting diode 200 and the dichromatic φ filter 100. In particular, the lighting further includes a housing 500. The housing 500 includes a base 510, a cover 520, a heat sink 530 and a terminal 540. The cover 520, the heat sink 530 and the terminal 540 are respectively connected to the base 510. The light emitting diode 200 is disposed on the heat sink 530, the dichroic filter 100 is disposed on the cover 520, and the lamp cover 300 is disposed on the base 510. Fig. 3 is a cross-sectional view taken along line 3-3 of Fig. 1. In other words, 'the light emitted from the LED 200 to the dichroic filter 100' will pass through the dichroic filter 100, and the light outside the preset band will be 2 M380423. The color filter 100 is refracted. The light that has just passed through the dichroic calender sheet and the light that is refracted by the two colors (four) and the light sheet 1GG are irradiated onto the globe 3 (10). Specifically, after the light-emitting diode and the power source are supplied, the light-emitting 200 emits light to the dichroic filter 100, and the first light (four) in the light band is passed through the two-color (four) light sheet 1 () On the - position - 310 of the lampshade. The wavelength in the light is preset; the second light 220 outside the skin is refracted by the dichroic filter 1 并 and illuminates the second position 320 of the globe 300. Due to the different bands of light: and different colors, the first light 21 〇 & second light 220 projected on the lamp cover 300 are respectively different colors, so that two or more different colors of light are generated on the lamp cover 3 . The term "preset band" as used above refers to the characteristic of a dichroic filter. Each of the dichroic filters 100 allows light in a portion of the wavelength range to pass through and refract light outside the wavelength range. The range of wavelengths that can pass is the preset band. For example, the preset wavelength band is 465 nm to 525 ηι ϊ 1, which allows blue light and green light having a wavelength of 465 nm or more to pass through, and refracts green light having a skin φ of 525 nm or more and its color light. For example, the preset wavelength band is 525 nm to 550 nm, and green light having a wavelength of 525 nm or more can pass and refract green light having a wavelength of 550 nm or more and its color light. How to determine the preset band of each dichroic filter is not a technical feature of the present invention, so it will not be described here. In one embodiment of the present invention, when the second light ray 220 illuminates the second position 320 of the light cover 300, two or more colors of light can be produced. For example, when the dichroic filter 100 has a predetermined wavelength band of 560 nm to 49 〇 nm, approximately green light can pass therethrough. Therefore, the fifth light ray 210 passing through the fifth M380423 of the dichroic filter 100 is green, and when illuminated at the first position 310 of the globe 300, it appears green. The other second light 22 〇〇 refracted by the dichroic filter 1 〇, ‘ is light other than green. Since the light of different wavelengths is refracted, the angle of refraction is also different, so that the second ray 220 is refracted by the dichroic filter 1 ’, and the effect of splitting is also produced. Therefore, when the second light 22 is illuminated at the second position 320 of the globe 300, it will appear blue and red. Further, two or more different colors of light can be produced on the lamp cover 300. Please refer to Fig. 4 and Fig. 5'. Fig. 4 is a perspective view of another embodiment of the present invention. Fig. 5 is an exploded view of Fig. 4 of the present invention. In this embodiment, the lighting fixture comprises a dichroic filter 1 , a light emitting diode 200 and a projection screen 400. The light emitting diode 200 is configured to emit light to the dichroic filter 100, and the projection screen 4 is disposed on one side of the dichroic filter 100. Specifically, the lighting device further includes a casing 5 (the casing 500 includes a base 510, a cover 520, a heat sink 530 and a terminal 540. The cover 520, the heat sink 530 and the terminal 540 are respectively connected to the base 510. The dipole φ body 2〇0 is disposed on the heat sink 530. The dichroic filter 100 is disposed on the cover 520. The projection screen can be positioned at a fixed position such as a wall surface, a ceiling, or the like, or positioned on a stable frame. Fig. 6 is a side view of the light of the light-emitting diode 200 of Fig. 4 irradiated on the projection screen 400. Specifically, as described above, among the light beams emitted from the light-emitting diode 200, the first light passes through the dichroism. The filter 1 〇〇, the second ray 220 is refracted by the dichroic filter 1 ,, passes through the first ray 21 二 of the dichroic filter 100, and the dichroic filter 1 〇〇 The refracted second light ray 220 is respectively irradiated on a first position 41 〇 6 M380423 and a second position 420 of the projection screen 400. Thereby, two or more different colors of light are generated on the projection screen 400 as For decoration. Please refer to Figure 3 and Figure 6, respectively, in one of the implementations of this new model. In the formula, a reflector 6 is additionally included. The reflector 600 surrounds the LED 200 for reflecting the light emitted by the LED 2 to emit light toward the front of the reflector 600. The light reflected by the reflector 600 can be set in a range of 30 to 90 degrees. The second light 220 emitted by the LED 200 is refracted by the dichroic filter. The light color can be illuminated on the lamp cover 300. The term "light viewing angle" refers to the angle of light that can be seen from the side. For example, from the side, the light emitting diode 200 emits When the light is reflected by the reflector 600 and emitted, the light is fan-shaped, and the angle of the fan is the angle of view of the light. Please refer to Fig. 7, which is the view angle of the light of Fig. 3 is about 90 degrees. The cross-sectional view includes a third light 230 and a fourth light 240 when the visible angle of the light is about 90 degrees, and the wavelength of the third light 230 is in the dichroic filter. The wavelength of the fourth ray 240 in the preset band of 〇 The area between the third light 230 and the fourth light 240 is outside the preset wavelength of the dichroic filter. The area where the refracted light can project a more pronounced color. Please refer to section 8. Fig. 8 is a cross-sectional view of the light of Fig. 3 with a viewing angle of about 120 degrees. When the angle of view of the light increases, the maximum angle of the light can be emitted by the third light 230 and the fourth light 240, The displacement, but the area between the third ray 230 and the fourth ray 240 is smaller. It can be seen that the larger the viewing angle of the light M380423, the smaller the area where the refracted light can project the more obvious color will be reduced. . Therefore, setting the viewing angle of the light in the range of 30 degrees to 90 degrees allows the refracted light to be projected into a region of more pronounced color with a more appropriate size. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any person skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application attached.
