[0001] This utility model relates to an LED lighting fixture, specifically a ceiling-mounted LED lighting fixture comprising a first light source, a second light source, and a lamp body, wherein the first light source and the second light source are disposed in the lamp body, wherein the first light source is a surface light source and the second light source is a point light source. Background Technology

[0002] As we all know, various LED-based lighting fixtures have been widely used due to their excellent performance, especially in the field of ceiling lights, where LED-based ceiling lights are particularly widely used.

[0003] like Figures 1 to 2 As shown, this is a widely used LED ceiling light 1, which is widely used in commercial offices and office buildings.

[0004] In practical use, the aforementioned LED ceiling light 1 is generally installed on the roof, for example, assembled with the ceiling.

[0005] The aforementioned LED ceiling light 1 generally includes a frame 2 and a cover plate 3. The cover plate 3 covers the top of the frame 2. A light guide plate 4 is provided in the frame 2. An LED light source 5 is provided on the side of the light guide plate 4. In order to improve the optical effect, a reflective film 6 is generally provided on the top of the light guide plate 4, and a light-transmitting panel 7 is provided below the light guide plate 4. When the aforementioned LED ceiling light 1 is in use, the frame 2 is used to fasten the LED ceiling light 1 into the ceiling of the roof. The LED light source 5 is powered on and emits light. The light emitted by it shines through the light guide plate 4 to provide lighting for people.

[0006] Similar technologies to the aforementioned LED ceiling light 1 have been disclosed in patent documents such as CN201811102673.2 and CN201510013757.9.

[0007] However, the aforementioned LED ceiling light 1 still has many shortcomings in use, which are described below.

[0008] Firstly, in actual use, the aforementioned LED ceiling light 1 is generally used as the main lighting light. If the brightness of the LED ceiling light 1 is not high, it will not achieve the lighting effect. However, if the LED ceiling light 1 has high brightness and a large light emission angle, when people look directly at the LED ceiling light 1, their eyes will feel glare and be dazzling.

[0009] Secondly, the aforementioned LED ceiling light 1 only provides illumination and does not have a decorative lighting effect. If indoor lighting decoration is required, additional decorative lighting fixtures must be installed. As mentioned above, this is the main drawback of the prior art. Utility Model Content

[0010] The technical solution adopted by this utility model is as follows: a dual-light source ceiling LED lamp, which includes a first light source, a second light source, and a lamp body. The first light source and the second light source are disposed in the lamp body, which is disposed in an illumination space. The first light source is a surface light source used to generate ambient light, which illuminates the illumination space and enhances the lighting atmosphere. The second light source is a point light source used to generate illumination light, which illuminates the illumination space and provides illumination. The lamp body includes a ceiling light frame, which has a first light source cavity and a second light source cavity. The first light source is disposed in the first light source cavity, and the second light source is disposed in the second light source cavity.

[0011] A dual-light source ceiling LED light fixture includes a first light source, a second light source, and a lamp body. The first and second light sources are disposed within the lamp body, which is located in an illumination space. The first light source is a surface light source used to generate ambient light that illuminates the illumination space and enhances the lighting atmosphere. The second light source is a point light source used to generate illumination light that illuminates the illumination space and provides illumination. The lamp body includes a ceiling light frame with a first light source cavity and a second light source cavity. The first and second light sources are disposed within the first and second light source cavities, respectively.

[0012] The first light source includes a light guide plate and several LED light sources. The light generated by the several LED light sources passes through the light guide plate and is emitted from the cavity of the first light source. The ambient light generated by the first light source illuminates the lighting space to form an illumination area. The second light source has a light emission angle. The illumination light generated by the second light source illuminates the lighting space to form an illumination area. The illumination area is located within the illumination area. The second light source includes an optical lens and an LED point light source. The optical lens has an incident light end and an exit light end. The LED point light source corresponds to the incident light end. The illumination light generated by the LED point light source enters the optical lens from the incident light end and exits from the exit light end. The lens emission angle of the optical lens is the same as the emission angle of the second light source.

[0013] The dual-light source ceiling LED light fixture also includes a light source regulator. The second light source is mounted on the light source regulator, which can drive the second light source to rise or fall in the second light source cavity, thereby adjusting the size of the illumination area C of the second light source.

[0014] The beneficial effects of this utility model are as follows: Traditional ceiling lights are only equipped with surface light sources. When working, they can only provide illumination light through surface light sources, and their illumination brightness is limited. At the same time, they do not have the decorative lighting effect of ambient lighting. However, this utility model creatively integrates surface light sources and point light sources into the lamp body. The surface light source generates ambient light, which can enhance the lighting atmosphere, while the point light source generates illumination light, which can provide illumination light. The lamp of this utility model can significantly improve the lighting environment and greatly enhance the user experience. Attached Figure Description

[0030] like Figures 3 to 15 As shown, a dual-light source ceiling LED light fixture includes a first light source 100, a second light source 200, and a lamp body 300. The first light source 100 and the second light source 200 are disposed in the lamp body 300, which is disposed in an illumination space A.

[0031] like Figure 3 As shown, the first light source 100 is a surface light source, which is used to generate ambient light L1. The ambient light L1 illuminates the lighting space A and enhances the lighting atmosphere in the lighting space A.

[0032] In practice, the ambient light L1 can be light of different colors, or light of different colors with varying brightness, or other forms of light that can enhance the decorative effect of the lighting. The types of ambient light and the decorative effect of the lighting are existing technologies and will not be elaborated here.

[0033] In practice, the decorative light L1 also has a certain lighting effect.

[0034] The second light source 200 is a point light source, which is used to generate illumination light L2. The illumination light L2 illuminates the lighting space A and provides illumination light.

[0035] The design concept of this utility model is as follows: Traditional ceiling lights are only equipped with surface light sources. When working, they can only provide illumination light through surface light sources, and their illumination brightness is limited. At the same time, they do not have the decorative lighting effect of ambient lighting. This utility model creatively integrates surface light sources and point light sources into the lamp body 300. The surface light source generates ambient light L1, which can enhance the lighting atmosphere, while the point light source generates illumination light L2, which can provide illumination light. The lamp of this utility model can significantly improve the lighting environment and greatly enhance the user experience.

[0036] like Figures 4 to 6 As shown, the lamp specifically 300 includes a ceiling light frame 310, which has a first light source cavity 311 and a second light source cavity 312. The first light source 100 is disposed in the first light source cavity 311, and the second light source 200 is disposed in the second light source cavity 312.

[0037] In practice, the ceiling light frame 310 is provided with snap-on plates 313 around its perimeter, which allow the light fixture 300 to be snapped into the ceiling of the roof.

[0038] This invention simplifies the product structure and reduces production costs by integrating the first light source 100 and the second light source 200 into the ceiling light frame 310. In practice, the first light source 100 and the second light source 200 can be installed in the lamp body 300 without adding any other structures.

[0039] like Figure 7 As shown, in a specific implementation, the first light source 100 includes a light guide plate 110 and several LED light sources 120. The light generated by the several LED light sources 120 passes through the light guide plate 110 and shines out from the first light source cavity 311. The ambient light L1 generated by the first light source 100 shines on the lighting space A to form an illumination area C1.

[0040] In practice, several LED light sources 120 can be LED light sources of different colors to enhance the lighting atmosphere. In addition, several LED light sources 120 can be connected to a control IC at the same time to control the light emission state of the LED light sources, such as light intensity, intermittent light emission, etc., to enhance the lighting atmosphere. Furthermore, the light guide plate 110 can be covered with a light-transmitting color film to enhance the lighting atmosphere.

[0041] In practice, the first light source 100 has many preferred implementation methods, which are described below.

[0042] like Figure 8 As shown in Embodiment 1, several LED light sources 120 are arranged around the light guide plate 110. The light generated by the several LED light sources 120 enters the light guide plate 110 from the side 111 of the light guide plate 110 and then shines out from the bottom 112 of the light guide plate 110. The top 113 of the light guide plate 110 is covered with a reflective film.

[0043] like Figure 9 As shown in Embodiment 2, several LED light sources 120 are disposed on the top of the light guide plate panel 130. The light generated by the several LED light sources 120 enters from the top surface of the light guide plate panel 130 and then shines out from the bottom surface of the light guide plate panel 130.

[0044] like Figure 10 As shown in Embodiment 3, several LED light sources 120 are arranged around the light guide plate 110. The light generated by the several LED light sources 120 enters the light guide plate 110 from the side 111 of the light guide plate 110, and then shines out from the bottom surface 112 and the top surface 113 of the light guide plate 110.

[0045] like Figure 11 As shown in Embodiment 4, the light guide plate 110 includes a lower light guide plate 114 and an upper light guide plate 115. The upper light guide plate 115 protrudes from the top of the lower light guide plate 114. The light generated by the plurality of LED light sources 120 is emitted through the lower light guide plate 114 and the upper light guide plate 115 respectively. The design of the lower light guide plate 114 and the upper light guide plate 115 can further enhance the lighting atmosphere effect.

[0046] In practice, the light guide plate 110 in embodiment four can be configured as a cylinder, lantern, etc., the lower light guide plate 114 can be configured as a disc, square disc, etc., and the upper light guide plate 115 can be configured as a ring disc, round tube, square tube, etc.

[0047] like Figure 7 As shown, in a specific implementation, the second light source 200 has a light emission angle B, and the illumination light L2 generated by the second light source 200 illuminates the illumination space A to form an illumination area C2, which is located in the illumination area C1.

[0048] The larger the light emission angle B, the larger the area of ​​the illuminated region C2; the smaller the light emission angle B, the smaller the area of ​​the illuminated region C2.

[0049] In practice, since the first light source 100 is a surface light source, when the human eye E is in the illumination area C1 and looks directly at the first light source 100, there will be no problem of glare or blindness. However, since the second light source 200 is a point light source, when the human eye E is in the illumination area C2 and looks directly at the second light source 200, there will be a problem of glare or blindness. This invention can control the size of the illumination area C2 by controlling the light emission angle B of the second light source 200, thereby reducing the occurrence of glare or blindness.

[0050] In practice, the second light source 200 has many preferred implementation methods, which are described below.

[0051] like Figure 12As shown in Embodiment 1, the second light source 200 includes an optical lens 210 and an LED point light source 220. The optical lens 210 has an incident light end 211 and an exit light end 212. The LED point light source 220 corresponds to the incident light end 211. The illumination light L2 generated by the LED point light source 220 enters the optical lens 210 from the incident light end 211 and exits from the exit light end 212. The lens exit angle of the optical lens 210 is the exit light angle B of the second light source 200.

[0052] like Figure 13 As shown in Embodiment 2, the second light source 200 includes a reflector cup 230 and an LED point light source 220. The LED point light source 220 is disposed in the reflector cup 230, and the light emission angle of the reflector cup 230 is the light emission angle B of the second light source 200.

[0053] like Figures 14 to 15 As shown, in a specific implementation, the dual-light source ceiling LED light fixture also includes a light source adjuster 400, and the second light source 200 is disposed on the light source adjuster 400.

[0054] The light source adjuster 400 can adjust the position of the second light source 200 in the second light source cavity 312, thereby adjusting the size of the illumination area C2 of the second light source 200.

[0055] In practice, the light source regulator 400 can drive the second light source 200 to rise or fall in the second light source cavity 312, thereby adjusting the size of the illumination area C2 of the second light source 200.

[0056] In practical implementation, the lamp 300 includes a top cover 320, which is located on top of the ceiling light frame 310.

[0057] The light source adjuster 400 includes a guide post 410, a push post 420, and a lamp plate 430. The guide post 410 is fixedly mounted on the top cover 320 of the lamp body 300. A limiting piece 411 is provided at the bottom of the guide post 410. A spring 412 is sleeved on the guide post 410. Several second light sources 200 are mounted on the lamp plate 430. The guide post 410 passes through the lamp plate 430. The spring 412 is located between the lamp plate 430 and the limiting piece 411. The push post 420 is pressed against the top of the lamp plate 430.

[0058] When in operation, the push column 420 moves downward and presses down on the lamp panel 430, compressing the spring 412. At this moment, the lamp panel 430 and several of the second light sources 200 move downward in the ceiling light frame 310.

[0059] The push column 420 moves upward, and the spring 412 pushes the lamp panel 430. At this moment, the lamp panel 430 and several of the second light sources 200 move upward in the ceiling light frame 310.

[0060] In practical implementation, the push column 420 includes a screw 421 and a fixing nut 422. The fixing nut 422 is fixed on the top cover 320, and the screw 421 is screwed into the fixing nut 422. The push column 420 can be moved down or up by screwing the screw 421 into or out of the fixing nut 422.

[0061] In practical implementation, the push column 420 can also be replaced by an electromagnetic actuator, wherein the coil of the electromagnetic actuator is set on the top cover 320 and the magnetic block of the electromagnetic actuator is set on the lamp plate 430, and the lamp plate 430 is driven to move down or up by means of the magnetic force between the coil and the magnetic block.

[0062] In specific implementation, the aforementioned second light source 200 can also be an LED linear light source.
