TECHNICAL FIELD

[0001] The utility model belongs to lighting lamps and lanterns technical field especially, it relates to a preset many kinds of light color anti -dazzle ceiling lamp. BACKGROUND

[0002] The existing ceiling lamp is single in the lighting effect, most can only provide fixed color temperature and brightness light, cannot satisfy people's diversified demand to light color and atmosphere in different scenes, such as in reading, leisure, party scene, provide suitable light color and brightness can greatly improve experience. But the traditional ceiling lamp is difficult to do flexible switching, and part ceiling lamp has certain light adjusting function, but there will be light uneven, poor color rendering and other problems, affect the lighting quality and visual experience.

[0003] In the current lighting and display technology field, color mixing is as a key means to present rich colors, which has many implementation forms. Among them, the common prior art mainly focuses on two types:

[0005] Two is to use RGBW packaged into 3838 COB (chips on board) form, also combined with a lens to realize mixing.

[0006] In the first scheme, by fine control of the current size of each road, the single RGBW four-color LED light source is mixed to the target color. However, this way has obvious disadvantages, that is, the uniformity of the mixed color is poor, in the actual application scene, it is easy to lead to uneven color distribution, and the visual effect is greatly discounted, for example, in some high color consistency requirements of stage lighting, high-end indoor lighting scene, it cannot meet the professional requirements.

[0007] Looking back at the second kind of 3838 packaging COB scheme, although it performs relatively well in color mixing uniformity, it can meet more stringent color consistency standards, but this scheme faces great challenges in production and manufacturing links. Due to its structural characteristics, the precision requirement of the chip mounter is extremely high in the light source patching process, which not only requires enterprises to equip high-end precision equipment, but also greatly depends on the professional skills and rich experience of the operators. Strict process requirements directly lead to low yield and increased waste, which in turn makes the production cost soar, greatly limiting the large-scale promotion and application of this technology in the low-end market and cost-sensitive projects.

[0008] Therefore, it is necessary to develop and provide a lighting lamp with good color mixing effect and high cost performance, specifically a ceiling lamp, so that it has multiple preset light color modes to adapt to different scenes, and solves the problems of single function and poor lighting quality of the existing ceiling lamp.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, this utility model is an anti-glare ceiling light with multiple preset light colors, mainly including a ceiling light body 1, and a lamp panel 2, a soft light diffuser 3, an LED module 4, a reflector 5, and a diffuser inner frame 6 disposed within the ceiling light body 1. The LED module is equipped with and connected to an LED driver module 40, a control module 41, and a power supply module 42. A control diagram for this part can be viewed. Figure 5 .

[0027] LED module 4 is a crucial component for achieving multi-color effects and switching between different colors. It uses RGBW packaging in a 5050 COB form, making it a four-chip module. The four chips are a flame red R chip, a yellow-green G chip, a cyan-blue B chip, and a white W chip. The flame red R chip has a color temperature of 1150K to 1250K, the yellow-green G chip has a color temperature of 3750K to 3850K, the cyan-blue B chip has a color temperature of 100000 to 120000K, and the white W chip can have a warm white color temperature of 2700K to 3000K, a neutral white color temperature of 4000K to 5000K, or a cool white color temperature of 5000 to 6500K. The control module 41 has a built-in dynamic intelligent light mixing control algorithm, which mixes multiple colors of light by adjusting the current, and has multiple preset light color modes that can be selected with one click to adapt to different scenarios. At the same time, it ensures that the light is uniform and soft with high color rendering, improving lighting comfort and atmosphere creation capabilities, solving the problems of existing ceiling lights having single functions and poor lighting quality. Furthermore, it can be set up with a communication module or remote control module to allow users to adjust and control it using an APP or remote control.

[0028] Furthermore, it can be explained that the LED chips in LED module 4 are all 5050 surface mount LED chips. The precision requirements of the LED chip placement machine used for it are not as high as those for 3838 surface mount packaging. This is because 3838 surface mount packaging requires a 0201 placement machine, while this utility model can use a 0402 placement machine. This design choice can reduce costs, improve yield, and also allow this utility model to have multiple preset light color modes.

[0029] When this utility model has multiple adjustable light colors, it is necessary to control the emitted light to ensure that different colors of light do not cause glare and affect the user's experience. Specific design details include:

[0030] 1. The lamp panel 2 is made of optical grade acrylic mixed with nano light scattering particles, which can optimize the light scattering path and make the light distribution more uniform;

[0031] 2. The inner surface of the reflector cup 5 is sprayed with a high reflectivity coating, which can reflect the backward light forward to improve the light utilization rate, and the reflection angle is optimized to further avoid glare;

[0032] 3. The inside of the ceiling lamp body 1 is embedded with a light scattering inner frame 6, and the inner wall surface of the light scattering inner frame 6 is a designed auxiliary inner frame that can diffuse light, which can refract light multiple times to ensure uniform and soft light without dark areas;

[0033] 4. The soft light diffusion plate 3 is arranged above the lamp panel 2, i.e. the incident surface of the lamp panel 2, to further improve the uniformity and softness of the light, and the color rendering index reaches Ra>90.

[0034] Through the above design, different scene lighting needs can be controlled to different light colors. This design not only effectively improves the space atmosphere and use experience, but also protects the eyes, relaxes, and can be used for a long time without glare and dark areas. Preset multi-color light commercial and household use.

[0035] In use, the LED chip module 4 is fixed on the heat dissipation substrate inside the lamp body, the power cord is connected, the reflector cup 5 is installed to be located in the emission direction of the LED module 4, and the angle is adjusted; The soft light diffusion plate and the lampshade are installed in turn below the lamp body to ensure that the parts are tightly attached and there is no light leakage gap. The ceiling lamp is fixed on the ceiling through the installation base, and the power supply is connected. After turning on the power supply, the intelligent control chip of the control module 41 in the LED chip module 4 is initialized, the user sends light color adjustment instructions through the remote controller or mobile phone APP, and the control chip receives the signal. According to the preset algorithm, adjust the current size of each chip in the LED module 4 to change the luminous intensity and color ratio, realize light color switching and brightness adjustment, and monitor the lamp temperature in real time. When the temperature is too high, the power is automatically reduced to protect the lamp, ensuring stable operation. In different scenes, users can select the appropriate light color mode as needed, such as selecting a low-brightness warm light mode for night sleep to create a quiet and comfortable sleep environment, and selecting a multi-color dynamic light color mode for family gatherings to add a happy atmosphere.
