Strong, concentrated range of light, But sometimes it is more glaring, and the eyes are prone to fatigue or even injury after a long time. Some lamps use multiple low-power LEDs The array layout and the diffusion plate are uniform, which has the characteristics of weak light intensity and wide illumination range, but also due to the wide illumination range and low illumination brightness, which easily causes light pollution and waste in the non-irradiated area. In addition, in the prior art, there is also a multi-mode lighting table lamp, which is provided with high power at the same time. LED lamp beads and low-power LED lamp beads, two LED lamp beads are controlled by the control circuit, when the spotlight illumination is needed, the LED with higher power can be selected. The operation mode of the lamp bead plus the optical lens; conversely, when the flood illumination is required, the LED with lower power can be selected. The working mode of the lamp bead and the diffuser plate can meet the needs of different occasions, but in real life, the demand for the light source mode is more and more diversified. For example, in the exhibition occasions of jewelry, goldware and other jewelry, people hope to be in the showcase. At the same time, two modes of adjustable spotlighting and floodlighting are applied at the same time. The floodlighting mode makes the surrounding of the product full of brilliance to attract buyers. When the buyer needs to carefully tasting the product, the brightness of the two light sources is adjusted. The ratio allows the product to be carefully observed in the spotlight illumination mode. For example, indoors, people can work and learn in the spotlight illumination mode, and in the floodlight mode, the room can obtain a soft lighting atmosphere, but because of The above two light source modes are respectively controlled to be turned on and off, and the brightness cannot be adjusted, or the light source is a specific power, and the mode is single, which cannot meet various needs of people, so the prior art has a large use restriction, resulting in The LED table lamp is not suitable for use.

本实施例中,所述大功率 LED 灯珠 106 背向基板 104 的一侧设有光学透镜 109 ,所述小功率 LED 灯珠 107 背向基板 104 的一侧设有扩散片 110 。大功率 LED 芯片 106 和小功率 LED 灯珠 107 之间还设有灯饰件 111 。 In this embodiment, the side of the high-power LED lamp bead 106 facing away from the substrate 104 is provided with an optical lens 109, and the low power The LED lamp bead 107 is provided with a diffusion sheet 110 on one side of the back substrate 104. There are also lighting parts between the high-power LED chip 106 and the low-power LED lamp bead 107. .
如图 6 所示,当需要聚光照明为主,泛光照明为次时,增加较大功率的 LED 灯珠的光照强度,中间的集中光线增强,四周的发散光线减弱。如图 7 所示,当需要泛光照明为主,聚光照明为次时,可增加较小功率的 LED 灯珠的光照强度,四周的发散光线增强,中间的集中光线减弱。因此使台灯具备了多种混合照明的模式,以迎合不同场合的需要。 因此,本实用新型具有更广的使用适应性,同一台灯具有不同混合照明模式,方便用户使用。 As shown in Figure 6, when concentrated illumination is required, and floodlighting is secondary, increase the power of the LED. The light intensity of the lamp bead, the concentrated light in the middle is enhanced, and the divergent light around it is weakened. As shown in Figure 7, when the floodlighting is required, and the spotlighting is secondary, the LED with less power can be added. The light intensity of the lamp bead, the divergent light around it is enhanced, and the concentrated light in the middle is weakened. Therefore, the desk lamp has a variety of mixed lighting modes to meet the needs of different occasions. Therefore, the utility model has wider adaptability for use, and the same lamp has different mixed illumination modes, which is convenient for the user to use.
