Detailed Description
Example (b):
as shown in fig. 1-3, a hall decorative lamp for playing a koto includes a light source 111, the light source includes a light emitting surface 111a, the light emitting surface 111a emits a first light 121, and further includes a light reflecting cup 101, the light reflecting cup 101 includes a reflecting surface 104, the reflecting surface 104 is a part of a spherical surface, an edge of the reflecting surface 104 surrounds to form a light receiving opening 102, the reflecting surface 104 is provided with a light emitting opening 103, the light emitting surface 111a is located at a spherical center of the spherical surface and emits light toward the reflecting surface 104, the first light 121 enters the light reflecting cup 101 through the light receiving opening 102, a part of the first light 121 entering the light reflecting cup 101 exits from the light emitting opening 103 and forms a second light 122, and a light spot formed by the second light 122 exiting from the light emitting opening 103 is in a strip shape; the LED backlight module further comprises a lens 105, the lens at least comprises an arc surface 105a, the arc surface 105a covers the light outlet 103, and the second light 122 exits after passing through the arc surface 105 a. To obtain a well-defined elongated spot, it is first necessary to make the second light 122 emitted from the light outlet 103 form an elongated spot, which requires the light outlet 103 to be elongated. However, since the light exit 103 is disposed on the reflection surface 104, the edge of the light exit 103 is formed by an arc, and for this purpose, the light exit 103 needs to be formed by two relatively long arcs and two relatively short arcs. At this time, the top view of the light outlet 103 is shown in fig. 3, and the light outlet 103 is a strip shape on the two-dimensional plane in the figure, so that the second light 122 emitted from the light outlet 103 can form a strip-shaped light spot. However, the elongated light spot is limited by the light emitting angle of the second light 122 emitted from the light outlet 103, and the boundary of the light spot is not obvious, so the present solution introduces the lens 105, and the arc surface 105a of the lens 105 covers the light outlet 103. The lens 105 receives the second light 122 from the light outlet 103, and converges or diverges the second light 122. Under the action of the lens 105 on the light emitting angle of the second light 122, the light distribution of the second light 122 is more uniform, so that the long-strip-shaped light spot boundary formed by the second light 122 is clearer, and the visual effect is more attractive. After solving the problem of light spots, the light energy utilization rate needs to be improved, so that the brightness of the final emergent light is higher. It can be known from the optical principle that a beam of light emitted from the center of sphere returns to the center of sphere after being reflected by the spherical surface where the center of sphere is located. Based on the above principle, to improve the utilization efficiency of the first light 121, the reflection surface 104 is a part of a spherical surface, and the light emitting surface 111a is located at the spherical center of the reflection surface 104, and the light emitting surface 111a emits the first light 121 toward the reflection surface 104. In this embodiment, the light emitting surface 111a is preferably a light emitting surface 111a capable of scattering and reflecting light emitted by itself.
The lens 105 is required to cover the light outlet 103, since the light outlet 103 is not a circular symmetrical pattern, a larger lens 105 is required to cover the light outlet 103, and to solve this problem, the size of the lens 105 can be increased on one side, and therefore, the lens 105 is in a strip shape. The length direction of the lens 105 is consistent with the length direction of the light spot, the arc surface 105a is arranged along the length direction of the lens 105, the arc surface 105a is located on one surface, away from the light receiving opening 102, of the lens 105, and the surface, facing the light outlet 103, of the lens 105 is a plane. In order to obtain an elongated light spot, the top view of the light outlet 103 is selected to be an elongated two-dimensional plane. At this time, the longitudinal direction of the second light 122 forming a spot is coincident with the longitudinal direction of the light outlet 103 in plan view. Therefore, the lens 105 in this embodiment is also preferably elongated to fit the light exit 103. In order to minimize the volume of the lens 105 and also to receive the second light 122, the length direction of the lens 105 needs to be consistent with the length direction of the light spot formed by the second light 122, and the arc surface 105a needs to be arranged along the length direction of the lens 105. In order to better receive the second light 122, the side of the lens 105 receiving the second light 122 is a plane. The cambered surface 105a emits the second light 122 which is finally shaped, and the cambered surface 105a is arranged on the side of the lens 105 far away from the light receiving opening 102.
After solving the problem of fitting the lens 105 with the light outlet 103, we need to consider what shape of the arc surface 105a is selected. In this embodiment, the arc surface 105a has two forms, namely, the arc surface 105a is a concave surface that is concave toward the inside of the lens 105, or a convex surface that is convex toward the outside of the lens 105. When the arc surface 105a is a concave surface, the lens 105 diffuses the second light 122, so that the second light 122 can form a large strip-shaped light spot in a short distance, and the lens is suitable for highlighting an article in a short distance. When the curved surface 105a is a convex surface, the lens 105 acts as a beam-closing function for the second light 122, so that the light spot formed by the second light 122 is small and suitable for illuminating a certain object at a long distance. The two concave forms are not limited, but need to be selected according to the area of the concert hall and the distance from the light fixture to the koto. In order to facilitate the arrangement of the light outlet 103, the light outlet 103 in this embodiment is preferably a spherical extension formed by reflecting surfaces. However, the light exit 103 itself is an arc surface due to the spherical extension, which makes the lens 105 unable to cooperate with the light exit 103, and thus the second light 122 cannot be completely received by the lens 105. Therefore, the light source comprises a plurality of lenses 105, the length direction of the plurality of lenses 105 is consistent with the length direction of the light spot, and the plurality of lenses 105 are uniformly arranged along the length direction of the light spot. Only if the length directions of the lenses 105 are consistent with the length direction of the light spot, the length directions of the lenses 105 are consistent with the extending direction of the light outlet 103, so that the lenses 105 are completely covered on the light outlet 103 after being spliced, and the second light 122 is not emitted without passing through the lenses 105.
In this embodiment, in order to ensure that the light emitting surface 111a can reflect the light emitted by itself, it is preferable that the light source 111 includes a light emitting device 111b and a wavelength conversion device 111c, the light emitting device 111b emits an excitation light 123, the excitation light 123 excites the wavelength conversion device 111c, the excited wavelength conversion device 111c emits the first light 121, and the wavelength conversion device 111c is located at the center of the sphere of the reflecting surface 104. The wavelength conversion device 111c works by converting the excitation light into stimulated light, which is the first light 121 in this embodiment. The wavelength conversion device is divided into two types according to the structure, one type is a transmission type wavelength conversion device 111c which consists of a transparent heat conduction substrate and a fluorescent material arranged on the transparent heat conduction substrate, and in order to prevent the waste of the stimulated light, a reflecting film which transmits exciting light and reflects the stimulated light is arranged between the fluorescent material and the transparent heat conduction substrate; the second is a reflective wavelength conversion device 111c, which is composed of a heat-conducting metal substrate and a fluorescent material, wherein one surface of the metal substrate facing the fluorescent material has a function of reflecting light. Since both of the wavelength conversion devices 111c have the property of reflecting the light emitted by themselves, the wavelength conversion device 111c is placed at the center of the reflecting surface 104, so that a part of the first light 121 reaches the reflecting surface 104 and is reflected back to the wavelength conversion device 111c, and the part of the first light 121 can be emitted toward the reflecting surface 104 again, thereby improving the utilization rate of the first light 121. For convenience of use, the transmissive wavelength conversion device 111c is preferred in this embodiment.
Manufacturing errors or damages and the like inevitably occur in the manufacturing and transportation processes of the light reflecting cup 101, so that part of the first light 121 reflected by the light reflecting surface 104 cannot return to the wavelength conversion device 111c, and further the first light 121 is emitted from the light receiving opening 102. For this purpose, a fixing plate 106 is further included, the fixing plate 106 covers the light receiving opening 102, a groove 106a is provided on a side of the fixing plate 106 facing the light reflecting cup 101, the wavelength conversion device 111c covers the groove 106a, and the light emitting device 111b is fixed in the groove 106 a. In this embodiment, the fixing plate 106 performs the following functions: firstly, light leakage is avoided, and the fixing plate 106 covers the light receiving opening 102, so that the first light 121 which may be emitted from the light receiving opening 102 cannot be emitted. And a reflective material may be further disposed on a surface of the fixing plate 106 facing the reflective cup 101, so as to further improve the utilization rate of the first light 121. Secondly, the fixing and heat conducting functions, in this scheme, the wavelength conversion device 111c not only covers the groove 106a, but also needs to be connected with the fixing plate 106 in a heat conducting manner. This is because the wavelength conversion device 111c generates heat in the process of converting the excitation light to emit the first light 121, and the fixing plate 106 can perform the functions of heat conduction and heat dissipation. Similarly, the light emitting device 111b generates heat during the light emitting process, so that when the light emitting device 111b is disposed in the groove 106a, the heat generated by the light emitting device 111b is transferred to the fixing plate 106, and thus the fixing plate 106 also performs the fixing and heat conducting functions on the light emitting device 111 b. To increase the heat dissipation speed, the fixing plate 106 is preferably made of a metal material. The light emitting device 111c may be selected as a laser diode or an LED light source as needed in consideration of the volume, power consumption, light intensity, and the like.
The present invention is not limited to the embodiments described above, but the embodiments are only preferred embodiments of the present invention and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should fall within the patent coverage of the present invention.
