Description

Technical Field

[0001] The present invention relates to the field of lamps, and in particular to a lamp and a method for improving the light efficiency of the lamp. Background Art

[0002] In the field of interior lighting design, ceiling lamps that use diffuse reflection from the ceiling to achieve soft lighting are widely used because they can create a comfortable lighting environment. These ceiling lamps do not have a light source that directly shines downward, but only emit light upward. The light is diffusely reflected downward by the ceiling to illuminate the interior space. However, existing ceiling lamps of this type generally have technical bottlenecks in light efficiency and light distribution, making it difficult to meet users' demand for high-quality lighting.

[0003] Traditional ceiling lamps based on diffuse reflection from the ceiling mostly use direct light sources, and the light is still unevenly distributed after being reflected by the ceiling. Due to the lack of scientific planning of the light source's emission angle and the ceiling reflection path, high-brightness light spots are formed where the light accumulates, and a large amount of light is concentrated in the area directly below the lamp, which can easily cause visual fatigue and cannot provide truly soft light. This type of ceiling lamp is not only dazzling but also makes the overall lighting uniformity in the room poor. The light in the space far away from the lamp is lost due to multiple reflections, and the brightness drops sharply, resulting in generally low lighting uniformity in the entire lighting space. Therefore, it is difficult to achieve the ideal diffuse reflection effect of "seeing light but not seeing the lamp". At the same time, in order to enhance the reflection effect, some products supplement the luminous flux by increasing the light source power or increasing the number of light sources, but this not only aggravates the local glare problem, but also leads to a large amount of light energy waste due to the absorption and scattering of light by the ceiling.

[0004] Therefore, how to improve the lighting efficiency while maintaining a single light source to achieve soft and uniform lighting of diffuse ceiling lamps is an industry pain point that needs to be solved urgently. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a lamp, including a shell, a light-transmitting member, a main support frame and a light source device, the light source device including a mounting substrate and a light-emitting body, the mounting substrate having a mounting base surface for mounting the light-emitting body, and the light-emitting body is configured to emit light; the position of the light source device is raised so that the mounting base surface approaches the upper edge of the shell from the bottom to the top or exceeds the upper edge of the shell upward, so that the upper edge of the shell avoids interference with the lateral light emitted by the light source device from the light-transmitting member; the lamp diffuses the light of a single light source laterally, and cooperates with the avoidance of the shell and the light-transmitting member to form a larger light spot with better uniformity, thereby improving the lighting efficiency and making the light perception of the entire space better.

[0006] A method for improving the luminous efficiency of a lamp is further provided. The luminous efficiency is improved by lifting the light-emitting body so that the mounting base height of the light-emitting body approaches the upper edge of the shell or exceeds the upper edge of the shell; the upper edge of the shell that is not transparent to light is located at the bottom of the light-transmitting component, and the lateral light passing through the light-transmitting component can avoid the shell and propagate outward.

[0007] The technical solution of the present invention is achieved as follows: A lamp, comprising: The housing is located at the outer edge of the lamp, and a light-transmitting member is provided on the housing, and the light-transmitting member protrudes upward from the housing; A main support frame is disposed in the housing, and the main support frame is configured as a main body support; The light source device is arranged on the main support frame, and the light source device includes a mounting substrate and a light-emitting body, wherein: A mounting substrate is provided on the main support frame, and the mounting substrate has a mounting base surface for mounting the light-emitting body; a light emitting body, disposed on the mounting substrate and located within the light-transmitting member, the light emitting body being configured to emit light; The position of the light source device is raised until the installation base approaches the upper edge of the shell from bottom to top or exceeds the upper edge of the shell, so that the upper edge of the shell avoids interfering with the lateral light emitted by the light source device / illuminant from the light-transmitting member.

[0008] In the prior art, the light of the light source device is emitted upward from the light-transmitting member, and its outer side is blocked by the outer shell and cannot emit light laterally; the mounting base of this solution is the upper surface of the mounting substrate. By raising the height of the light source device, that is, the mounting base is close to or upwardly exceeds the upper edge of the outer shell, the position of the light-emitting body is higher than that in the prior art, and is closer to or higher than the upper edge of the outer shell. The outer shell only partially blocks the lateral light emitted by the light-emitting body or does not block it at all, allowing the obliquely emitted light to reach the ceiling smoothly, so that the light of the light source device is emitted laterally to a farther position on the ceiling, and the light distribution is more uniform and the range is wider, thereby solving the problem of light accumulation, making the formed light spot larger and more uniform, and the indoor lighting is therefore softer and more uniform.

[0009] In summary, the lamp diffuses the light from a single light source laterally, and cooperates with the outer shell and the light-transmitting part to form a larger and more uniform light spot, thereby improving the lighting efficiency and making the entire space more luminous. In addition, in terms of structure, when the lamp forms a light spot of the same size as the existing technology, the distance between the lamp and the ceiling can be shorter, thereby shortening the overall height of the lamp.

[0010] Preferably, the light source device further includes a reflector, which is disposed on the main support frame and is located on the inside of the lamp relative to the light-emitting body. The reflector has a reflective surface facing outward and tilted upward. The reflective surface is configured so that light emitted inward by the light-emitting body is reflected by the reflective surface and propagates obliquely outward and upward. With respect to the light emitted inward, the reflective surface is provided with an angled reflective surface to reflect it outward and to a position close to the light from outside, thereby further improving the light efficiency and reducing light loss. If the reflective surface is vertical or the angle is too small, the light from inside will be reflected too far and directly hit the wall instead of the ceiling, resulting in low brightness. In this way, the light will be too dispersed, losing the brightness advantage. Therefore, it is necessary to adjust the degree of dispersion and concentration of the light.

[0011] Preferably, the outer shell and the light-transmitting member are annular, the main support frame is disc-shaped, and the reflecting surface is conical. The conical reflecting surface can reflect the inner light from different directions to the surrounding areas of the lamp to maintain uniform light.

[0012] Preferably, the reflector includes an inclined main reflector and a horizontal mounting portion, wherein the reflective surface is formed on the main reflector, and the mounting portion is mounted on the mounting base surface of the mounting substrate; the mounting portion is provided with a plurality of avoidance holes for avoiding the light emitting element, and the upper surface of the mounting portion has a reflective effect; the mounting portion and the main reflector are integrally formed. The light utilization rate of the light emitting element is less than 100%, and some unused light will be reflected upward or outward by the reflector mounting portion; the mounting portion and the main reflector are integrally formed, and after the horizontal mounting portion is installed, the main reflector is naturally installed in a predetermined posture, facilitating the installation of the inclined main reflector.

[0013] Preferably, the outer shell and the light-transmitting member are annular, and the main support frame is disc-shaped, with the main support frame located in the outer shell. Mounting ridges are provided at both inner and outer ends of the light-transmitting member, and a mounting groove is provided on the inner side of the outer shell. The mounting ridges on the outer side of the light-transmitting member are inserted into the mounting groove, and the mounting ridges on the inner side of the light-transmitting member are located on the main support frame. The lamp also includes an upper cover plate, which is mounted above the main support frame and located on the inner side of the light-transmitting member. The outer edge of the upper cover plate abuts the mounting ridges on the inner side of the light-transmitting member from top to bottom, and maintains the mounting ridges between the main support frame and the upper cover plate. This facilitates quick installation of the light source device and the light-transmitting member.

[0014] Preferably, the inwardly inclined angle of the reflective surface is 8-15 degrees. Within this angle range, the degree of dispersion and concentration of light is more conducive to forming a soft and uniform lighting effect while maintaining overall brightness.

[0015] Preferably, the light-transmitting member is a three-dimensional member, and its cross-sectional profile extends in the height direction. Conventional light-transmitting members are horizontal plates, which restrict the light source device to emitting light only upwards. In contrast, the three-dimensional light-transmitting member of this solution not only allows the light source device to emit light upwards, but also allows light to pass laterally through the three-dimensional light-transmitting member, expanding the light reaching the ceiling.

[0016] Preferably, the light-transmitting member comprises at least one main light-emitting portion rising from the bottom, wherein the main light-emitting portion has a height after rising, and lateral light can pass through the main light-emitting portion.

[0017] Preferably, the light-transmitting element includes at least one inclined, vertical, or curved main light-emitting portion, the bottom of which is located on the housing and extends upward from the housing. Conventional light-transmitting elements are generally annular plates. The light-transmitting element of this lamp is three-dimensional. Because the light of this lamp is not primarily emitted from the top, but from the sides, the main light-emitting portion must extend in the height direction to allow lateral light to pass through.

[0018] Preferably, the light source comprises a light-emitting diode (LED) and a lens, with the lens disposed on the LED. The lens is configured such that light emitted by the LED, after passing through the lens, radiates sideways and reduces the amount of light directed upward. The lens diffuses the light laterally and reduces the amount of light directly striking the ceiling, allowing the LED light to pass through the translucent element and strike a greater location on the ceiling. Furthermore, due to the angled distribution of the light, the light distribution is also wider, thereby resolving the problem of light accumulation and creating a larger and more uniform light spot, resulting in softer and more uniform indoor lighting.

[0019] Preferably, the mounting substrate is arranged horizontally on the main support frame; a plurality of light-emitting diodes are provided on the mounting substrate, and each light-emitting diode is provided with the lens. This solution also takes into account production costs. The reflective surface only needs to be made of reflective paper or reflective board, which does not increase the cost significantly. The structural arrangement in this solution can keep the mounting substrate in a flat plate shape rather than a three-dimensional conical surface, which can significantly save production costs and ensure that the lamp can be produced at a low cost.

[0020] Preferably, the lens has a groove, the LED is located in the groove, and the inner surface of the groove is aspherical. The lens is a TV lens, and the light-emitting surface of the LED is a vertical light-emitting surface. The lens reduces the frontal illumination of the vertical light-emitting surface, and the light is bent to the side by the lens, thereby diffusing the light to amplify the light spot and improve the light effect.

[0021] Preferably, the lens is a TV lens.

[0022] Preferably, the highest position of the housing is no higher than the light-emitting surface of the LED. In this solution, the housing has the best light-blocking effect. The light emitted by the LED is higher than the housing, so no light is blocked by the housing, which can further reduce light loss and improve light efficiency.

[0023] Preferably, the main support frame has a horizontal main body, a receiving groove is formed between the main body, the housing, and the light-transmitting member, and the upper surface of the main body is the bottom surface of the receiving groove; the light source device is located in the receiving groove, and the mounting base is higher than the bottom surface of the receiving groove. Structurally, the elevated mounting base is reflected in the fact that the light source device is no longer mounted on the bottom surface of the receiving groove, and the distance between the mounting base and the bottom surface of the receiving groove is greater than the thickness of the mounting substrate. Therefore, the light source device is raised as a whole and approaches or exceeds the upper edge of the housing; when the light source device is located deep in the receiving groove, most or even almost all lateral light will be blocked. However, when the light source device is located shallow in the receiving groove as in the present embodiment, the housing will avoid most lateral light.

[0024] Preferably, the main body has a raised portion that protrudes upward from the upper surface of the main body; the mounting substrate is mounted on the raised portion. By providing the raised portion on the main body, the mounting height of the light source device is raised to be close to or above the upper edge of the housing.

[0025] Preferably, the installation base surface is 3-10 mm higher than the bottom surface of the accommodating groove.

[0026] A method to improve the lighting efficiency of lamps: Arrange the light source toward the ceiling and elevate it; Lifting treatment: Raise the height of the illuminator relative to the upper edge of the shell, so that the height of the mounting base of the illuminator is close to the upper edge of the shell or exceeds the upper edge of the shell; make the upper edge of the shell that cannot transmit light be located at the bottom of the light-transmitting component, so that the lateral light passing through the light-transmitting component can avoid the shell and propagate outward; The light emitted by the luminous body passes through the light-transmitting member and hits the ceiling at an inclined angle and is diffusely reflected by the ceiling to propagate obliquely downward.

[0027] The light emitted by the LED passes through the lens and is emitted at multiple angles. There is both external light that is smoothly emitted outward and illuminates the ceiling, and internal light that is emitted inward. As for the external light, since the non-translucent outer shell is lower than the light-transmitting element through which light passes, and the light-emitting element itself is raised, the external light can pass through the light-transmitting element unobstructed and be emitted at a certain inclination angle to the ceiling farther away. After diffuse reflection from the ceiling, it is then transmitted downward at a certain inclination angle, achieving soft and uniform indoor lighting over a large area, thereby improving the light efficiency of the lamp.

[0028] As a preferred embodiment, the luminous body is subjected to a reflection treatment of the inner light; Reflection of Inner Light: The light emitted by the LED toward the interior of the lamp is called inner light. This light is reflected by placing a reflector inside the LED. The upper end of the reflective surface of the reflector is tilted inward, and the reflective surface is tilted outward and upward. After passing through the lens, the inner light hits the reflective surface and is reflected outward and upward, exiting the light-transmitting element. Because the inner light cannot directly illuminate the ceiling outside the lamp, it is reflected outward by the tilted reflective surface as it travels toward the center of the lamp, or inward. The reflected inner light has the same direction as the outer light, but at a different angle. Therefore, it can be used to expand the light spot and improve lighting efficiency, thereby increasing light utilization, reducing light loss, and maintaining lighting brightness.

[0029] As a preference, the luminous body is subjected to light diffusion treatment; Light Diffusion: A lens is placed outside the LED to diffuse the light from the LED to the side, reducing the amount of light directed upward. The lens also plays a significant role, focusing on diffusing the light from the LED, focusing it to the side, enhancing its intensity and preventing a decrease in brightness as the spot size increases.

[0030] The design starting point, concept and beneficial effects of the present invention using the above technical solution are: In the prior art, the light of the light source device is emitted upward from the light-transmitting member, and its outer side is blocked by the outer shell and cannot emit light laterally; the mounting base of this solution is the upper surface of the mounting substrate. By raising the height of the light source device, that is, the mounting base is close to or upwardly exceeds the upper edge of the outer shell, the position of the light-emitting body is higher than that in the prior art, and is closer to or higher than the upper edge of the outer shell. The outer shell only partially blocks the lateral light emitted by the light-emitting body or does not block it at all, allowing the obliquely emitted light to reach the ceiling smoothly, so that the light of the light source device is emitted laterally to a farther position on the ceiling, and the light distribution is more uniform and the range is wider, thereby solving the problem of light accumulation, making the formed light spot larger and more uniform, and the indoor lighting is therefore softer and more uniform.

[0031] In summary, the lamp diffuses the light from a single light source laterally, and cooperates with the outer shell and the light-transmitting part to form a larger and more uniform light spot, thereby improving the lighting efficiency and making the entire space more luminous. In addition, in terms of structure, when the lamp forms a light spot of the same size as the existing technology, the distance between the lamp and the ceiling can be shorter, thereby shortening the overall height of the lamp.

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of the present invention, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0037] The specific implementation of the present invention is as follows: like Figure 1-6 As shown, the present invention provides a lamp, comprising: The housing 1 is located at the outer edge of the lamp, and a light-transmitting member 4 is provided on the housing 1, and the light-transmitting member 4 protrudes upward from the housing 1; A main support frame 2 is provided in the housing 1 and is configured as a main body support; The light source device 3 is arranged on the main support frame 2, and the light source device 3 includes: The mounting substrate 33 is provided on the main support frame 2, and the mounting substrate 33 has a mounting base surface 331 for mounting the light emitting body 31; a light emitting body 31 , which is disposed on a mounting substrate 33 and located within the light-transmitting member 4 , and is configured to emit light; The position of the light source device 3 is raised until the installation base surface 331 approaches the upper edge of the housing 1 from bottom to top or exceeds the upper edge of the housing 1 upward, so that the upper edge of the housing 1 avoids interfering with the lateral light emitted by the light source device 3 from the light-transmitting member 4.

[0038] In the prior art, the light of the light source device 3 is emitted upward from the light-transmitting member 4, and its outer side is blocked by the shell 1 and cannot emit light laterally; the mounting base 331 of this solution is the upper surface of the mounting substrate 33. By raising the height of the light source device 3, that is, the mounting base 331 is close to or upwardly exceeds the upper edge of the shell 1, it is higher than the light-emitting body 31 in the prior art, closer to or higher than the upper edge of the shell 1, and the shell 1 only partially blocks or completely blocks the lateral light emitted by the light-emitting body 31, allowing the obliquely emitted light to reach the ceiling smoothly, thereby making the light of the light source device 3 emitted laterally to a farther position on the ceiling, the light distribution is more uniform and the range is also wider, thereby solving the problem of light accumulation, making the formed light spot larger and more uniform, and the indoor lighting is therefore softer and more uniform; in the prior art, the mounting base of the light source is generally 40-60 mm away from the upper edge of the shell, while the mounting base 311 in this solution is within 10 mm from the upper edge of the shell 1, or even flush with or exceeds the upper edge of the shell 1.

[0039] In summary, the lamp diffuses the light from a single light source laterally, and cooperates with the outer shell 1 and the light-transmitting member 4 to form a larger light spot with better uniformity, thereby improving the lighting efficiency and making the entire space more luminous. In addition, in terms of structure, when the lamp forms a light spot of the same size as the prior art, the distance between the lamp and the ceiling can be shorter, thereby shortening the overall height of the lamp.

[0040] Furthermore, the light-emitting body 31 includes a light-emitting diode 311 and a lens 312, and the lens 312 is arranged on the light-emitting diode 311; the lens 312 is configured so that the light emitted by the light-emitting diode 311 radiates sideways after passing through the lens 312 and reduces the light emitted directly upward; the lens 312 can diffuse the light toward the sides and reduce the light directly hitting the ceiling, so that the light from the light-emitting diode can pass through the light-transmitting member 4 and hit a farther position on the ceiling. Moreover, because the light has an inclined angle, the range of light distribution can also be wider, thereby solving the problem of light accumulation, making the formed light spot larger and more uniform, and the indoor lighting is therefore softer and more uniform.

[0041] The light source device 3 also includes a reflector 32, which is arranged on the main support frame 2 and is located on the inner side of the lamp relative to the light-emitting body 31. The reflector 32 has a reflective surface 321 facing outward and inclined upward. The reflective surface 321 is configured so that the light emitted inward by the light-emitting body 31 is reflected by the reflective surface 321 and then propagates obliquely outward and upward; for the light emitted inward, it is reflected outward at an angle by setting the reflective surface 321, and is reflected to a position close to the outer light, further improving the light efficiency and reducing light loss; if the reflective surface 321 is vertical or the angle is too small, the inner light will be reflected too far and directly hit the wall instead of the ceiling, and the brightness will also be low. In this way, the light will be too scattered and lose the brightness advantage. Therefore, it is necessary to adjust the degree of dispersion and concentration of the light; the inward tilt angle of the reflective surface 321 is 8-15°. Within this angle range, the degree of dispersion and concentration of the light is more conducive to forming a soft and uniform lighting effect that maintains overall brightness. In this embodiment, a tilt angle of 10° is selected.

[0042] Specifically, if Figure 1-4As shown, the lamp is disc-shaped as a whole, the shell 1 and the light-transmitting member 4 are annular, the main support frame 2 is a disc-shaped metal member made of aluminum, and can also be used for heat dissipation of the light source device 3; the light source device 3 is arranged in a ring shape near the outer edge of the upper surface of the lamp, and the lamp also has another light source that emits light downward; the ring shape of the light source device 3 can make the formed light spot evenly distributed on the ceiling, and also has a certain effect of increasing the softness and uniformity of indoor lighting; considering the production cost, the light source device 3 is divided into a plurality of identical components, which are arranged circumferentially and formed into a ring, and the light-transmitting member 4 is also treated in the same way; the light source device 3 includes a plurality of mounting substrates 33, The plate 33 is arranged horizontally on the main support frame 2, and each mounting substrate 33 is curved with an arc, but maintains a flat plate shape; there are a number of light-emitting diodes 311, which are arranged on the mounting substrate 33 and the number and position of the light-emitting diodes 311 arranged on each mounting substrate 33 are the same, and each light-emitting diode 311 is provided with the lens 312; this solution also takes into account the production cost issue, and the reflective surface 321 only needs to be made of reflective paper or a reflective plate, and the increased cost is not high, and the structural setting in this solution can keep the mounting substrate 33 in a flat plate shape rather than a three-dimensional conical surface, which can save a lot of production costs and keep the lamp capable of low-cost production.

[0043] The reflector 32 is made of a material with high reflectivity, such as a reflective plate, reflective paper, a mirror, or a stainless steel plate. In this embodiment, reflective paper is used as the reflector 32. The reflective surface 321 is a conical surface. The conical reflective surface 321 can reflect the inner light from different directions to the surrounding areas of the lamp to maintain uniform light. The reflector 32 also includes an inclined main reflective portion 323 and a horizontal mounting portion 322. The reflective surface 321 is formed on the main reflective portion 323, and the mounting portion 322 is mounted on the mounting base surface 331 of the mounting substrate 33. The mounting portion 32 2 is provided with a plurality of avoidance holes for avoiding the illuminant 31, and the upper surface of the mounting portion 322 has a reflective effect; the mounting portion 322 and the main reflector 323 are integrally formed; the light utilization rate of the illuminant 31 cannot reach 100%, and a portion of the unused light will be reflected upward or outward by the mounting portion 322 of the reflector 32; the mounting portion 322 and the main reflector 323 are integrally formed, and after the horizontal mounting portion 322 is installed, the main reflector 323 is naturally installed in a preset posture, which facilitates the installation of the tilted main reflector 323.

[0044] In this embodiment, the light-transmitting member 4 is transparent as a whole and is a three-dimensional member. The cross-sectional profile of the light-transmitting member 4 has an extension in the height direction. The light-transmitting members 4 in the prior art are all horizontal plates, so that the light source device 3 can only emit light upward, which is highly restrictive. However, the light-transmitting member 4 in this solution is a three-dimensional member. The light source device 3 can not only emit light upward, but also pass through the three-dimensional light-transmitting member 4 laterally, so that the light irradiated on the ceiling is expanded. Therefore, the light-transmitting member 4 includes at least one main light-emitting portion 41 rising from the bottom. The main light-emitting portion 41 has a height after rising upward, and the lateral light can pass through the main light-emitting portion 41. In other words, the light-transmitting member 4 includes at least an inclined, vertical, or curved main light-emitting portion 41, the bottom of which is located on the housing 1 and extends upward from the housing 1. The light-transmitting member 4 in the prior art is generally annular, but the light-transmitting member 4 of this lamp is three-dimensional. Because the light of this lamp is not primarily emitted from the top, but from the side, the main light-emitting portion 41 must extend in the height direction to allow lateral light to pass through. In this embodiment, the main light-emitting portion 41 extends upward and inward from the housing 1 in an arc. A flat surface portion 42 is also integrally formed on the inner portion of the main light-emitting portion 41, which also allows light to pass through.

[0045] like Figure 6 As shown, the lens 312 is a TV lens 312. Structurally, the lens 312 has a groove, the light-emitting diode 311 is located in the groove, and the inner surface of the groove is aspherical. The light-emitting surface of the light-emitting diode 311 is a vertical light-emitting surface. The lens 312 reduces the front illumination of the vertical light-emitting surface, and the light is bent to the side by the lens 312, thereby allowing the light to diffuse out, thereby enlarging the light spot and improving the light effect.

[0046] like Figure 6 As shown, the highest position of the housing 1 is no higher than the light-emitting surface of the LED 311; in this solution, the housing 1 has the best effect of not blocking light, and the light emitted by the LED 311 is higher than the housing 1, so no light will be blocked by the housing 1, which can further reduce light loss and improve light efficiency; in the radial direction, the housing 1 is located outside the light source device 3, and the thickness of the housing 1 and the distance the housing 1 protrudes outward are jointly configured to prevent the user from directly looking at the light source device 3 at any position in the room; in this embodiment, the upper edge of the housing 1, that is, the highest position of the housing 1 is lower than the light-emitting surface of the LED 311, and the upper edge of the housing 1 is slightly lower than the mounting base 331, and the distance between the upper edge of the housing 1 and the mounting base 331 is 0.5 mm.

In the present embodiment, the mounting base 331 is 4.8 mm higher than the bottom surface of the receiving groove; a protrusion 211 is provided on the main body 21, and the protrusion 211 protrudes upward from the upper surface of the main body 21; the mounting substrate 33 is mounted on the protrusion 211; by arranging the protrusion 211 on the main body 21, the mounting height of the light source device 3 is raised so that it is close to or exceeds the upper edge of the housing 1.

[0048] The luminaire can be assembled quickly and easily: like Figure 2-4, 8-10, the lamp also includes an upper cover plate 5, a lower cover plate 6 and a bottom diffuser plate 7, the shell 1 and the light-transmitting member 4 are annular, the main support frame 2, the upper cover plate 5, the lower cover plate 6, and the bottom diffuser plate 7 are disc-shaped, and the main support frame 2 is located in the shell 1; specifically, a mounting bar 11 extends inward from the lower portion of the shell 1, the bottom diffuser plate 7 is placed on the mounting bar 11, the main support frame 2 is placed on the bottom diffuser plate 7, the main support frame 2 also includes a connecting portion 22 located in the middle and sunken relative to the main body 21 and located The abutment portion 23 extends downward from the edge of the main body 21, and the lower cover 6 is connected to the connecting portion 22 from the bottom up and abuts the bottom diffuser 7 against the connecting portion 22. The abutment portion 23 abuts against the bottom diffuser 7 at the same time. At this time, they can float up and down in the shell 1. In order to lock them, the inner and outer ends of the light-transmitting member 4 are provided with mounting ridges 43. A mounting groove 12 is opened on the inner side of the upper part of the shell 1. The mounting ridge 43 on the outer side of the light-transmitting member 4 is inserted into the mounting groove 12. The mounting ridge 43 on the inner side of the light-transmitting member 4 is inserted into the mounting groove 12. 43 is located on the raised portion 211 of the main support frame 2; before this, first install the light source device 3 on the raised portion 211, the light-emitting body 31 is pre-installed on the mounting substrate 33, the reflector 32 is placed on the mounting substrate 33, the mounting substrate 33 is placed on the raised portion 211 and the reflector 32, the mounting substrate 33 and the raised portion 211 are fixed by screws; continue to install the upper cover 5, the upper cover 5 is installed above the main support frame 2, the upper cover 5 is located on the inner side of the light-transmitting member 4, and the outer edge of the upper cover 5 is pressed from top to bottom Connect the mounting ridge 43 on the inner side of the light-transmitting member 4 and keep the mounting ridge 43 between the raised portion 211 of the main support frame 2 and the upper cover plate 5, and fix the upper cover plate 5 to the main body 21 by screws, and the installation is completed at this time; wherein, the light-transmitting member 4 plays a role of connecting the upper and lower parts. After the upper cover plate 5 and the main support frame 2 are installed, the light-transmitting member 4 is locked and pressed downward against the main support frame 2, and the main support frame 2 is pressed downward against the bottom diffuser plate 7, and the lower cover plate 6 is installed on the main support frame 2 and prevents the bottom diffuser plate 7 from detaching downward.

[0049] The light source that emits light downward is installed on the main support frame 2 above the bottom diffusion plate 7 and faces downward.

[0050] Furthermore, a method for improving the light efficiency of a lamp is provided: Arrange the light-emitting body 31 toward the ceiling above, and perform light diffusion and lifting processing on the light-emitting body 31; Light diffusion treatment: A lens 312 is provided outside the LED 311. The light emitted by the LED 311 radiates sideways after passing through the lens 312 and reduces the light emitted directly upward. Lifting treatment: Raise the height of the illuminator 31 relative to the upper edge of the housing 1 so that the mounting base 331 of the illuminator 31 is close to or exceeds the upper edge of the housing 1; the upper edge of the housing 1 that is not transparent to light is located at the bottom of the light-transmitting member 4, so that the lateral light passing through the light-transmitting member 4 can avoid the housing 1 and propagate outward; The light emitted by the light emitting diode 311 passes through the lens 312 and the light-transmitting element 4 and hits the ceiling at an oblique angle. The light is diffusely reflected by the ceiling and propagates obliquely downward.

[0051] After passing through the lens 312, the light emitted by the LED is emitted at multiple angles. There is both external light that is smoothly emitted outward and illuminates the ceiling, and internal light that is emitted inward. As for the external light, since the housing 1, which is not transparent to light, is lower than the light-transmitting member 4, the external light can pass through the light-transmitting member 4 unobstructed and be emitted at a certain angle to the ceiling farther away. After diffuse reflection from the ceiling, it is then transmitted downward at a certain angle, achieving soft and uniform indoor lighting over a large area, thereby improving the light efficiency of the lamp.

[0052] Furthermore, the light emitting body 31 is subjected to a reflection process of the inner light; Reflection processing of inner light: The light emitted by the light-emitting diode 311 toward the inside of the lamp is the inner light. The inner light is reflected by setting a reflector 32 inside the light-emitting diode 311; the reflective surface 321 on the reflective component 32 is tilted inward, and the reflective surface 321 is tilted toward the outside and upward. After passing through the lens 312, the inner light hits the reflective surface 321 and is reflected outward and upward to exit the light-transmitting component 4.

[0053] As for the inner light, since the inner light cannot directly illuminate the ceiling outside the lamp, when the inner light propagates toward the center or the inside of the lamp, it is reflected outward by the inclined reflecting surface 321. The reflected inner light has the same direction as the outer light but at a different angle. Therefore, it can also be used to expand the light spot and improve the light efficiency, thereby increasing the light utilization rate, reducing light loss, and maintaining the lighting brightness.

[0054] In the above method, the light utilization rate of the light-emitting diode 311 is firstly improved, and both the external light and the internal light can achieve a diffusion effect, thereby reducing light loss and maintaining the lighting brightness. Then, by tilting the light propagation path, the light irradiated on the ceiling can be diffused outward instead of accumulating above the lamp, thereby expanding the size of the light spot formed by the lamp and its coverage range. After diffuse reflection from the ceiling, the overall lighting feeling is better, softer and more uniform.

[0055] like Figure 7As shown, the size comparison between the light spot A formed by the existing ceiling diffuse reflection lamp and the light spot B formed by the lamp of this embodiment is shown, where the dotted line represents the diameter of the lamp. When the lamps are of the same size, the light spot B formed by the lamp of this embodiment is much larger than the existing lamp in both size and coverage.
