Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a downlight with integrated light control and heat dissipation. Background Art

[0002] A downlight is a decorative lighting fixture that is embedded in the ceiling and radiates light downwards. As a concealed lighting fixture embedded in the ceiling, all light is projected downwards, which belongs to direct light distribution. Different reflectors, lenses, blinds, and bulbs can be used to achieve different lighting effects.

[0003] Downlights do not take up space and can add a soft atmosphere to the space. They are generally used more in hotels, homes, and coffee shops. Existing downlights will have radiators installed separately on the light board and the outer shell to dissipate the heat of the light board when in use, thereby reducing the risk of overheating and damage to the light board. At the same time, in order to control the unified glare value (UGR) of the downlight, a light control component will be installed on the downlight to control the UGR of the downlight, thereby improving the naked eye's perception of the downlight light.

[0004] With respect to the above-mentioned related technologies, the existing downlight heat sink and light control assembly are separately installed on the downlight, which results in too many components in the whole downlight and increases the cost of the downlight. Utility Model Content

[0005] In order to simplify the structure of a downlight and reduce the manufacturing cost of the downlight, the present application provides a downlight with integrated light control and heat dissipation.

[0006] The light control and heat dissipation integrated downlight provided in this application adopts the following technical solutions:

[0007] The light-controlling and heat-dissipating integrated downlight comprises a reflective shell, a lamp panel and a fixing part. The reflective shell is provided with a light outlet, and the lamp panel is installed in the reflective shell through the light outlet. The reflective shell is covered with a light-controlling film, and the reflective shell is made of a heat-conducting material. The fixing part is used to fix the lamp panel in the reflective shell.

[0008] By adopting the above technical scheme, firstly, when the downlight is started, the heat emitted by the light panel is conducted to the outside air through the reflective shell, thereby reducing the temperature at the light panel and reducing the overheating and damage of the light panel; secondly, the radiator and the light control component are replaced with a reflective shell with a light control film and made of heat dissipation material, and the two functions are integrated on the reflective shell, thereby reducing the overall structure of the downlight and thus reducing the manufacturing cost of the downlight; thirdly, the reflective shell and the light control film can adjust the unified glare value of the downlight, achieve the photobiological safety RG0 and UGR vertically less than 19, and reduce the discomfort of the downlight light to the naked eye.

[0009] Preferably, a heat dissipating silicone grease layer is provided between the bottom of the groove of the reflective housing located at the light outlet and the lamp board.

[0010] By adopting the above technical solution, compared with directly pressing the light board against the reflective shell to conduct heat, the heat generated by the light board is conducted to the reflective shell through the heat dissipation silicone grease layer due to the good thermal conductivity of the heat dissipation silicone grease, thereby further improving the heat conduction efficiency and reducing the chance of overheating and damage to the light board.

[0011] Preferably, the fixing part includes a fixing bolt, a first mounting opening is provided on the reflective shell, a second mounting opening is provided on the light board, and the second mounting opening is provided with an internal thread; the fixing thread is passed through the first mounting opening and is arranged in the reflective shell, and the fixing bolt is threadedly connected to the light board through the second mounting opening.

[0012] By adopting the above technical solution, the second mounting opening is arranged on the lamp board, and the fixing bolts pass through the reflective shell and are directly connected to the lamp board, thereby reducing the use of other fixing components and reducing the manufacturing cost of the downlight.

[0013] Preferably, a charging socket is provided on the lamp panel, a connecting hole is provided on the reflective shell, and an input end of the charging socket is penetrated into the reflective shell through the connecting hole.

[0014] By adopting the above technical solution, the charging socket is integrated on the lamp board, which reduces the volume of the charging components on the lamp board, thereby reducing the overall volume of the downlight.

[0015] Preferably, the reflective housing is provided with a shading ring along the light emitting direction of the downlight and on a side away from the light board, and the reflective housing is provided with an optical plate on a side of the shading plate away from the light board.

[0016] By adopting the above technical solution, the shading ring limits the light emitted by the light panel to the inside of the reflective shell, reduces the light from the connecting hole, and makes the light emitted from the light outlet in a predetermined direction.

[0017] Preferably, the downlight further comprises a snap ring, which is sleeved on one end of the reflective housing along the light emitting direction and away from the lamp board, and the snap ring is provided with a locking member for locking the downlight in a predetermined position.

[0018] By adopting the above technical solution, the reflective cup is received by a clamping ring, and then the clamping ring is fixed at a predetermined installation position by a locking member, so that it is convenient for the staff to adjust the reflective cup after completing the installation of the downlight.

[0019] Preferably, the locking member includes a torsion spring, which includes an elastic portion and a connecting rod portion that are connected to each other. A connecting frame is provided on the retaining ring, a clamping groove is provided on the connecting frame, the elastic portion of the torsion spring is installed on the connecting frame through the clamping groove, a locking rod is provided on the connecting frame, and the elastic portion is sleeved on the locking rod.

[0020] By adopting the above technical solution, when installing the torsion spring, the elastic part is first squeezed to reduce the overall volume of the elastic part, so that the elastic part enters the clamping groove through the locking rod, and then the elastic part is released, and the elastic part that has been deformed and restored is sleeved on the locking rod to fix the torsion spring as a whole in the clamping groove. This connection structure utilizes the elastic part of the torsion spring that can be retracted and deformed. Workers only need to press the elastic part to install the torsion spring, thereby realizing the rapid disassembly and assembly of the torsion spring on the downlight.

[0021] Preferably, reinforcing ribs are provided on the clamping ring along the circumferential direction.

[0022] By adopting the above technical solution, reinforcing ribs are used to enhance the overall structural strength of the clamping ring, thereby improving the overall bearing capacity of the clamping ring on the reflective housing and the light panel.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Replace the radiator and light control components with a reflective housing with a light control film and made of heat dissipation material to reduce the overall structure of the downlight, thereby reducing the manufacturing cost of the downlight;

[0025] 2. The reflective shell and light control film can adjust the uniform glare value of the downlight, achieve photobiological safety RG0 and UGR vertical less than 19, and reduce the discomfort of the downlight to the human eye. BRIEF DESCRIPTION OF THE DRAWINGS

A heat dissipation silicone grease layer is provided between the bottom of the groove of the reflective shell 1 located at the light outlet 11 and the lamp board 2. When the lamp board 2 generates heat, the heat is quickly transferred to the reflective shell 1 through the heat dissipation silicone grease layer, so as to reduce the situation that the heat conduction speed is slow after the lamp board 2 is heated, so that the temperature of the lamp board 2 itself is too high, resulting in damage to the lamp board 2;

[0034] The reflective shell 1 is covered with a light-controlling film. The reflective shell 1 is made of a heat-conducting material. In the present embodiment, the heat-conducting material is highly reflective thermally conductive aluminum. Using highly reflective thermally conductive aluminum as the material of the reflective shell 1 can quickly conduct the heat generated by the lamp board 2 to the air; at the same time, the light-controlling film of the highly reflective thermally conductive aluminum can refract the light emitted by the lamp board 2, so that the UGR of the light emitted by the downlight is less than 19, and the glare level is RG0, thereby reducing the impact of the downlight on the human eye.
