Problems solved by technology

The disadvantage of this technology is that once the light source is turned on, the color and brightness of the emitted light cannot be changed automatically, and the human eye will inevitably experience visual fatigue under the long-term fixed light source, which will lead to mental fatigue and decreased concentration at the same time.
[0004] The existing dimming scheme is: one or more white LEDs form an LED module, and the brightness and color temperature can be changed by manual knob dimming or touch dimming. There is no automatic dimming scheme

Embodiment 1

[0024] see figure 1 , a new type of auto-dimming LED light source assembly composed of a single-color LED chip, including a control module 1, a drive module 2 connected to the control module 1, and a white LED chip 3 connected to the drive module 2, wherein the white LED Chip 3 can also be any one of various monochromatic LED chips such as cool white, warm white, red, orange, yellow, green, blue, purple, etc. in other colors.

[0025] The control module 1 has a built-in single-chip microcomputer or other integrated circuits, and is equipped with an application program to control the brightness and chromaticity changes of various monochrome LED chips. Through this application program, the drive current in the drive module 2 is controlled to change appropriately to make the white LED chip The brightness of 3 changes slowly, realizing the purpose of automatically adjusting and changing the brightness of the LED light source assembly according to the natural light, and slowing dow...

Embodiment 2

[0026] Embodiment 2: A new type of automatic dimming LED light source assembly composed of two kinds of single-color LED chips, including a control module 1, a drive module 2 connected to the control module 1, a red LED chip 4 and a green LED chip 4 respectively connected to the drive module 2 The LED chips 5 are jointly formed.

[0027] Wherein, the LED module composed of the red LED chip 4 and the green LED chip 5 can also be any two combinations of various single-color LED chips of other colors such as cool white, warm white, orange, yellow, blue, purple, etc. become.

[0028] The control module 1 has a built-in single-chip microcomputer or other integrated circuits, and is provided with an application program for controlling the brightness and chromaticity changes of the red LED chip 4 and the green LED chip 5 respectively, through which the driving current in the driving module 2 is controlled to drive the red color The LED chip 4 and the green LED chip 5 correspondingly...

Embodiment 3

[0029] Embodiment 3: A new type of automatic dimming LED light source assembly composed of three kinds of single-color LED chips, including a control module 1, a drive module 2 connected to the control module 1, a white LED chip 3 connected to the drive module 2, and a red LED chip The LED chip 4 and the green LED chip 5 are jointly formed. The driving module 2 controls and drives various monochromatic LED chips to emit light, and the control module 1 controls the brightness and chromaticity changes at different times.

[0030] The LED module composed of white LED chip 3, red LED chip 4 and green LED chip 5 can also be any three kinds of monochromatic LED chips of other colors such as cool white, warm white, orange, yellow, blue, purple, etc. A combination, or a combination of any other color with any two of white, red, and green, or a combination of two colors with any of white, red, and green are embodiments.

[0031] Similarly, the control module 1 has a built-in single-chi...

Abstract

The invention discloses an automatic light-changing LED light source assembly. The automatic light-changing LED light source assembly comprises a control module with an internally-installed integrated circuit and an LED module composed of one or more unicolor LED chips. The control module is electrically connected with various unicolor LED chips through a driving part; the integrated circuit is provided with an application program for controlling the brightness and the chroma of the various unicolor LED chips so that the objective of automatic light-changing adjustment can be achieved. The driving part can be arranged independently or arranged in the control module or installed on the same substrate as the unicolor LED chips separately. The LED module is composed of multiple unicolor LED chips packaged independently or multiple LED chips packaged on one substrate or multiple LED chips packaged in a hybrid mode. According to the invention, the effect of automatic light-changing can be achieved just through the control program without manual adjustment so that people can feel the change of light similar to natural light, and visual fatigue can be effectively reduced.

Description

technical field [0001] The invention relates to an LED light source, in particular to an automatic dimming LED light source assembly. Background technique [0002] Currently mass-produced LED light source assemblies on the market, including LED bulb lamps, LED fluorescent tubes, LED spotlight light source assemblies, LED downlight light source assemblies, LED table light light source assemblies, etc., are basically fixed by fixed white LEDs. current to drive. [0003] The existing LED light source assembly is composed of one or more LEDs with a fixed color and a driver with a fixed or manual current adjustment. The disadvantage of this technology is that once the light source is turned on, the color and brightness of the emitted light cannot be changed automatically. Human eyes will inevitably experience visual fatigue under long-term fixed light source irradiation, and at the same time lead to mental fatigue and decreased concentration. [0004] The existing dimming schem...
