Embodiment

[0023] This embodiment is applied in an occasion where white light illumination is required.

[0024] Such as figure 1 As shown, the internal structure of the LED ceiling lamp in this embodiment includes a plurality of LEDs 1 , the aforementioned control unit 2 and a power supply unit. The power supply unit converts the 220V AC power into the DC power used by the LEDs 1 and the control unit 2, so as to supply power to them.

[0025] These LEDs are dominated by white LEDs. Specifically, using 100 0.15W white LEDs (W, stands for white), the single luminous flux is 18lm (lumen, the international unit of luminous flux); 20 0.25W red LEDs (R, stands for red red), A single luminous flux is 6lm; 20 0.25W green LEDs (G, stands for green green), a single luminous flux is 12lm; and, 20 0.25W blue LEDs (B, stands for blue blue), a single The luminous flux is 6lm. When the total power of these LEDs is fully turned on, the total power is 25W, and the total luminous flux is 2280lm.

Abstract

The invention discloses an LED ceiling lamp, comprising a light source. The light source comprises at least one white light LED and at least one colorful light LED. The illumination effects of the ceiling lamp are soft, non-glare and relatively high in color rendering. The ceiling lamp can change light emitting color temperature flexibly.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED ceiling lamp. Background technique [0002] At present, with the development of the economy, indoor lighting, landscape lighting and architectural lighting have received more and more attention and attention. From the beginning, lighting only focused on brightness, and now it pursues beauty while pursuing brightness. From the initial general Lighting sources are now integrated into high-tech, and lighting sources and lighting methods are becoming more and more diversified, making our cities more and more beautiful at night. Especially with the advancement of LED technology, LED lighting has become increasingly popular. The combination of large-scale application of LED and electronic technology will develop various new applications and possibilities. [0003] The most widely used in various lighting occasions is white light lighting fixtures. However, if a single white LED is directly used as the...
