Detailed Embodiments

[0027] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments:

[0028] Embodiment 1:

[0029] This embodiment is a front IP65 waterproof rotating downlight, and its overall structure is as Figure 1 shown, and its sectional view is as Figure 2As shown in the figure, it includes: a main body, a face ring, an arc, a silicone ring, a waterproof groove, a silicone pad, a light source structure, and a lens. The arc is arranged on the face ring, the main body is installed on the face ring, a groove is provided on the arc of the face ring, and the silicone ring is fixed in the groove by glue (in other embodiments, it can also be fixed by other means). The light source structure is installed inside the main body, the waterproof groove is arranged on the upper surface of the main body, the silicone pad is installed in the waterproof groove, the lens is installed on the silicone pad, and the lens compresses the silicone pad and is integrally fixed by the buckle on the main body.

[0030] Based on the above structure, the front IP65 waterproof rotating downlight provided in this embodiment has the following beneficial effects:

[0031] The lens is used to shape the angle of the light emitted by the light source structure, making the light-emitting angle larger, so as to meet the requirement that the light emitted by the light source structure has no granularity under the condition of a lower lamp body height, and ensure the light-emitting effect while reducing the thickness of the direct-down lighting fixture.

[0032] The arc on the face ring ensures the smooth rotation of the main body part. There is a groove on the arc of the face ring, and the silicone ring is fixed in the groove by glue, providing a good damping feel for the rotation of the lamp body inside the face ring, and playing a role in preventing the front water spray from entering the rear main body. There is a waterproof groove on the upper surface of the lamp body, the silicone pad is placed in this groove, the lens compresses the silicone pad and is integrally fixed by the buckle on the lamp body cover, so that the front water cannot enter the inside of the lamp through the lens installation gap. It can realize the rotation angle adjustment and the strong anti-water spray requirement on the surface of the downlight. The production end concentrates the light source part in one body and fixes it by snap connection, realizing simple and convenient production and installation. The structural design of the silicone pad, the silicone ring and the concentric arc of the product enables the front of the product to reach the IP65 waterproof level, greatly broadening its application scenarios.

[0033] Further, the silicone ring is an annular silicone ring, which fits the size and shape of the groove.

[0034] The size (circle size) and shape of the silicone pad fit the water discharge groove, and the height of the silicone pad is slightly higher than the step surface of the waterproof groove, improving the waterproof effect.

[0035] Among them, the light source structure includes a lamp board, a PCB board, and a reflector bowl. The PCB board is connected to the lamp board, and the reflector bowl is installed above the lamp board and below the lens. The reflector bowl is used to converge the light emitted by the lamp board, which can effectively reduce the light loss and make the light output rate higher, further improving the light output effect.

[0036] In this embodiment, the lamp board is an LED lamp board. Compared with traditional lamp boards, the LED lamp board adopts advanced LED lighting technology, has high luminous efficiency, can provide brighter and more uniform light, and has a better lighting effect. At the same time, the light-emitting angle of the LED lamp board can be adjusted according to different lighting requirements, making the light more in line with actual needs. Its service life far exceeds that of traditional lamp boards, which can save a large amount of replacement and maintenance costs. It does not produce harmful gases and radiation and is pollution-free to the environment. At the same time, the power consumption of the LED lamp board is low, which can effectively save energy and reduce energy consumption costs. Its structure is simple and more convenient to maintain. Just clean the surface of the lamp regularly to maintain the lighting effect.

[0037] Furthermore, the main body and the face ring are fixed by the first fixing screws. The main body includes an upper lamp body cover and a lower lamp body cover. The lamp board is fixed to the lower lamp body cover by the second fixing screws. The lens is installed on the upper lamp body cover (the waterproof groove is arranged on the upper surface of the upper lamp body cover). The upper lamp body cover and the lower lamp body cover are integrally fixed by the internal buckles of the lower lamp body cover. The combined main body is fixed to the face ring by the first fixing screws on both sides of the ear buckle. The PCB board is limited and fixed by the limiting groove inside the lower lamp body cover.

[0038] There are through holes provided at the bottom of the lower lamp body cover for inserting the power cord to provide working power for the light source structure.

[0039] The front IP65 waterproof rotating downlight provided in this embodiment meets the requirements of rotation angle adjustment and strong water spray prevention on the surface; the production end concentrates the light source part in one body and fixes it with buckles and screws, realizing simple and convenient production and installation.

[0040] Embodiment Two:

[0041] This embodiment provides a front IP65 waterproof rotating downlight, which further optimizes and improves the solution of Embodiment One.

[0042] Generally, downlights dissipate the heat generated by the light source structure during operation by opening heat dissipation holes on the outer shell. Since the heat dissipation holes are directly exposed to the external environment, when it rains or water is splashed on them, the external water easily flows into the stage light through the heat dissipation holes, causing a short circuit in the circuit and damage.

[0043] The front IP65 waterproof rotating downlight provided in Embodiment One adopts a waterproof structure. Although it avoids water entering the main body, due to the sealed waterproof structure affecting the heat dissipation effect, when the downlight works for a long time, the internal heat cannot be dissipated, easily causing damage to the internal equipment.

[0044] A radiator is used to dissipate heat from the light source structure, and a heat dissipation channel is formed with the internal space of the lower lamp body cover and the through hole for the power cord at the lower part of the lamp body. This not only ensures the sealing of the installation space inside the main body, preventing the components inside the main body from being affected by water, but also ensures the effective evacuation of heat, improving the stability of the downlight during long-term operation, and taking into account the design requirements of heat dissipation and waterproofing.

[0045] Specifically, as Figure 1 shown, the radiator is installed below the lamp board, and the PCB board is limited and fixed through the limiting groove inside the lower lamp body cover. The PCB board is vertically installed below the radiator, enabling the radiator to form a heat dissipation space with the bottom of the lower lamp body cover, improving the heat dissipation effect. At this time, the through hole at the bottom of the lower lamp body cover also serves as a heat dissipation hole while inserting the power cord. In other embodiments, heat dissipation holes can also be separately provided at the bottom of the lower lamp body cover.

[0046] The radiator is placed in a limited position through the screw posts inside the lower lamp body cover, and the lamp board is fixed to the lower lamp body cover together with the radiator by fixing screws.

[0047] Furthermore, silicone is dot-coated on the surface of the radiator, which can fill the small gaps between the radiator and the lamp board, increasing the contact area between the radiator and the lamp board, enabling heat to be conducted out faster and more evenly, thereby improving the heat dissipation efficiency of the radiator. At the same time, it can also prevent gases such as oxygen and water vapor between the lamp board and the radiator from entering, avoiding heat conduction of the gases, making the heat dissipation ability of the radiator more stable, and protecting the surface of the radiator from mechanical damage.

[0048] In this embodiment, the radiator includes a lamp cylinder cooling fan and a heat dissipation fixing plate. The lamp cylinder cooling fan is installed below the heat dissipation fixing plate and fixed inside the lower lamp body cover through the heat dissipation fixing plate, and the lamp board is installed above the heat dissipation fixing plate.

[0049] Both the lamp board and the lamp cylinder cooling fan are in a ring structure. There are two notches on the upper surface of the heat dissipation fixing plate for fixing the PCB board. Thus, the PCB board is installed in the space inside the radiator.

[0050] In other embodiments, there are two notches on the upper surface of the heat dissipation fixing plate, and the PCB board is installed in the heat dissipation space at the bottom of the lower lamp body cover. The data cable connecting the PCB board and the lamp board passes through the notches.

[0051] Embodiment Three:

[0052] This embodiment provides a front IP65 waterproof rotating downlight, which further optimizes and improves the solution of Embodiment One in combination with specific application scenarios.

[0053] Commercial lighting is characterized by diversity, so different types of downlights need to be selected according to the various environmental conditions of the lighting venues. The goals of modern commercial lighting are clear and targeted. In order to highlight a certain function, specific designs are often required to set off the environment and reflect the specific nature and characteristics of the business. The nature of modern commercial lighting is determined by the purpose of lighting, and often uses regional multi-point light sources and light color space combinations to create an atmosphere.

[0054] However, the light intensity and color temperature of most existing downlights cannot be adjusted, resulting in a limited range of application scenarios for downlights. It is necessary to install multiple downlights with different color temperatures, which increases the cost of use. In addition, when used outdoors, rain, moisture or dust can easily enter the interior of the lamp, causing damage to internal components or affecting lighting. At the same time, most existing downlights are large in size, inconvenient to install, and have certain requirements for installation space, which cannot meet people's increasing usage needs.

[0055] In the light source structure, a temperature control and dimming device is added to meet the convenient dial dimming, so that the front IP65 waterproof rotating downlight provided in Example 1 can adjust the light brightness and color temperature according to the lighting requirements of different scenes, thereby expanding the scope of use of the front IP65 waterproof rotating downlight.

[0056] The specific manifestations are:

[0057] The light source structure includes a color temperature adjustment switch and a brightness adjustment switch, which are connected to the PCB board through a data line. The color temperature adjustment switch is used to adjust the color temperature of the LED light, and has a 6-level CCT toggle switch adjustment, which can achieve 2700-3000-3500-4000-5000 5-level color temperature selection and 2000-3000K DTW function; the brightness adjustment switch is used to adjust the power of the LED light, that is, to adjust the brightness of the LED light.

[0058] The PCB board is compatible with Triac or 0-10V dimming, and has a 3-speed power toggle switch to adjust the power to achieve 3-speed power selection; it has a 6-speed CCT toggle switch to adjust the color temperature of 2700-3000-3500-4000-5000 and a 2000-3000KDTW function. The color temperature adjustment switch, brightness adjustment switch and PCB board have corresponding functions.

[0059] Embodiment 4:

[0060] This embodiment provides a front IP65 waterproof rotating downlight, and its overall structure is as follows Figure 1 As shown, its cross-section is as follows Figure 2 shown.

[0061] Most of the dimmable waterproof rotating downlights on the market at present have problems such as complex structure, high cost, poor heat dissipation effect, inconvenient rotation, etc. The design of the downlight structure in this embodiment greatly optimizes the original problems.

[0062] Specifically, it is manifested as:

[0064] As Figure 2 shown: The main body part is a sphere, which is fixed on the face ring through a side shaft. The arc on the face ring ensures the smooth rotation of the main body part.

[0065] As Figure 2 shown in the enlarged view of B, there is a groove on the arc of the face ring. The annular silica gel ring is fixed in the groove by glue, providing a good damping feel when the lamp body rotates inside the face ring and playing a role in preventing water from the front from entering the rear main body.

[0066] As Figure 2 shown in the enlarged view of A, there is a waterproof groove on the surface of the upper lamp body cover. The silica gel pad is placed in this groove, and its height is slightly higher than the groove step surface. The lens compresses the silica gel pad and is integrally fixed through the buckle on the upper lamp body cover, preventing water from the front from entering the inside of the lamp through the lens installation gap.

[0067] The PCB board is limited and fixed through the groove inside the lower lamp body cover. The radiator is placed in a limited way through the screw posts inside. Silica gel is dot-coated on the surface of the radiator. The lamp board is fixed to the lower lamp body cover together with the radiator through the second fixing screw.

[0068] The reflector bowl is placed on the upper part of the lamp board. The lens upper lamp body cover semi-main body is integrally fixed in two parts through the internal buckle of the lower cover. The combined downlight main body is fixed through the first fixing screws on both sides of the ear buckle. The structural design of the silica gel washer and the concentric arc of the product enables the front of the product to reach the IP65 waterproof level, greatly broadening its application scenarios.

[0069] As Figure 1 and Figure 2 shown, springs are symmetrically installed on both sides of the face ring. On the one hand, the spring makes the face ring in a compressed state, so that after a long time of use, the sealing performance at the connection between the face ring and the lamp body can be ensured, guaranteeing the waterproof performance. On the other hand, by means of the spring, the downlight can be installed on the wall or ceiling, realizing the quick installation and removal of the downlight.
