Description

a ceiling lamp

technical field

The utility model relates to the field of lighting lamps, in particular to a colorful lighting lamp with reasonable structure and free color selection.

technical background

The lamps and lanterns that multiple colors are available for selection are existing general lighting equipment, and existing lamps and lanterns basically adopt colored incandescent lamp as light source. Due to the characteristics of incandescent lamps such as large calorific value, small area, and easy damage, the existing colorful lighting lamps have disadvantages such as uneven illumination, frequent replacement, maintenance, and high temperature, which make the existing colorful lights only play a role in actual use. From the perspective of decoration, few users will switch the light color according to their needs, which loses its original design purpose.

A general ceiling lamp is usually composed of a chassis, a lamp tube, a lampshade and a circuit structure. The chassis is installed on the ceiling to support the entire lamp structure. Generally, it adopts a flat structure. This structure determines that the circuit structure must be installed on the lower side of the chassis and on the same side as the lamp tube. In this way, not only the shape is complicated, and it is not easy to replace the lamp tube, but also the high temperature generated by the lamp will damage the circuit structure and reduce its service life. In particular, some existing ceiling lamps with automatic control structure have a large circuit structure or electrical components, which is very inconvenient to install on the same side as the lamp tube, and also blocks part of the light, resulting in uneven luminescence of the ceiling lamp. Affects lighting and aesthetics.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and to design a colorful lighting ceiling lamp with reasonable structure, beautiful and simple appearance, and easy maintenance.

The utility model realizes its purpose through the following technical solutions.

The utility model designs a ceiling lamp, which includes a ceiling lamp chassis, a lampshade, a lamp tube and electrical components. The lamp tube is installed between the chassis and the lampshade. The improved structure includes at least two lamp tubes. A platform is formed, and an installation cavity is formed on the other side of the platform, the above-mentioned lamp tubes are installed around the platform, and electrical components are installed inside the installation cavity. When the chassis is installed on the ceiling, the electrical components cannot be seen from the outside, the appearance is simple and beautiful, and it is also convenient for the replacement of the lamp tube, without blocking the light, the brightness of the ceiling lamp is uniform, and it has good lighting performance. Another function of the platform is to isolate the electrical components and lamps that generate a lot of heat, and to prevent dust and moisture from the electrical components, to protect the electrical components, and to prolong the service life of the ceiling lamp.

The use of lamp tubes has many advantages: low cost. Compared with existing light-emitting diodes, the cost of lamp tubes is very low, which can greatly reduce the price of lamps and facilitate the popularization and application of lamps. High brightness, the brightness of a lamp can be equivalent to multiple light-emitting diodes or incandescent lamps. Uniform brightness, suitable for use as lighting. Compared with incandescent lamps, the service life is longer, and the replacement frequency is greatly reduced. The calorific value is low, and the calorific value of fluorescent tubes is between light-emitting diodes and incandescent lamps. Due to the high cost of light-emitting diodes, it is the best choice to consider fluorescent tubes comprehensively. Moreover, the fluorescent tube also has the advantages of diverse shapes, suitable for different shapes, large luminous area, and simple control. Therefore the utility model comprehensively considers adopting the fluorescent tube as the light source to have its substantive significance, rather than a simple light source replacement.

The design of multiple lamps is convenient for users to choose, so as to achieve the purpose of color selection and mixing, such as choosing different colors of lighting in different environments. On the other hand, it is convenient to control the brightness of the lighting, so as to realize the purpose of setting an appropriate lighting brightness according to the specific environment.

For the purpose of humanization and energy saving, this design is further equipped with a night light on the platform, which is composed of multiple light emitting diodes installed side by side. In daily life, high-brightness lighting is not required all the time, so it is not necessary to turn on the lamp frequently. At this time, night lights can be used for lighting, which is energy-saving and environmentally friendly, and greatly reduces the switching frequency of the lamp, ensuring the use of lamps. life. The night light can be equipped with a wireless sensing device. Since the night light is used as auxiliary lighting and is generally used when the lighting tube is turned off, it is convenient to use the wireless sensing mode. The wireless sensing device can be a sound sensing device or an infrared sensing device.

In order to facilitate wiring, there are wire holes on the side of the platform. The power cords of the lamp tubes and night lights pass through the wire holes to connect with electrical components. No messy wiring can be seen from the front of the ceiling lamp, and the overall structure is beautiful and generous. A sub-platform is arranged on the periphery of the platform, and the back of the sub-platform is a hollow structure communicating with the installation cavity. The secondary platform is also provided with wire holes. In this way, the wires can be routed directly through the hollow structure on the back of the sub-platform, and the power cord can be routed directly to the corresponding position connected to the lamp tube, and then passed through the wire hole to connect with the lamp tube, which further simplifies the front structure of the chassis.

The electrical components mentioned above include the control circuit and the ballast. The ballast, as an electrical component that generates a lot of heat, should be isolated from the lamp tube so as not to affect the work of each other. The control circuit can be a simple circuit for controlling the lamp and night light switch, or a circuit for further controlling the brightness change of the lamp and color adjustment, or a more advanced circuit with wireless remote control and automatic induction. The function of the ceiling lamp is improved.

The lamp tube of the present utility model includes at least three lamp tubes of different colors, and preferably includes two colors of cool and warm. In order to achieve uniform distribution of light colors and make color mixing and adjustment more uniform, the light tubes adopt a circular structure and are nested inside and outside around the platform. The nested structure can simultaneously achieve the effects of luminous uniformity and light color mixing.

Since the chassis of the dome light is generally a thin plate structure, and is made of relatively fragile materials such as plastic or ceramics, at least one circle of raised ribs is provided on the chassis around the platform, which can play a role in the overall structure. The strengthening effect makes the structure more stable.

This design is equipped with lighting tubes and night lights suitable for different environments, and users can choose or adjust them arbitrarily. The lights are diversified and humanized. The appearance is beautiful and generous, and there is no messy wiring structure, which facilitates the replacement of the lamp tube. It has a good protective effect on electrical components and improves the service life of lamps. The rational cooperation of light-emitting diodes and fluorescent lamps not only meets the needs of daily life, but also makes rational use of electricity and saves energy. Nested lamp settings make light color mixing more natural. It has humanized control structure and flexible operation. Therefore, compared with the prior art, the utility model has substantive characteristics and progress.
