Abstract

The invention discloses a compound OLED (Organic Light Emitting Diode) and LED (Light Emitting Diode) light fitting comprising a bracket, a controller, one or more than one OLED device and one or more than one LED device, wherein both the OLED device and the LED device are arranged on the bracket; the LED device is an LED device other than green light, and the OLED device is an OLED device other than blue light; the OLED device and the LED device are connected with the controller, and the brightness of the OLED device and the brightness of the LED device can be respectively adjusted via the controller so that the light fitting can give out all kinds of lights; and the light fitting also comprises a scattered light reflection layer so that the light from the OLED device and the light from the LED device are given out through the reflection of the scattered light reflection layer. According to the invention, the LED device other than green light and the OLED device other than blue light are organically combined to integrate the advantages of two devices to a whole so that the light fitting has the advantages of stable performance, high efficiency and greatly prolonged service life; and meanwhile, the brightness of the OLED device and the brightness of the LED device can be respectively adjusted via the controller so that the light fitting can give out all kinds of lights and the color of the OLED device and the color of the LED device cannot be seen by users.

Description

technical field [0001] The invention relates to a lighting appliance, in particular to an OLED and LED composite lamp. Background technique [0002] OLED (Organic Light Emitting Diode) and LED (Light Emitting Diode) technologies are now relatively mature. We found that red OLED and green OLED have good performance and long service life, while blue OLED has the disadvantages of poor performance and short life. ; On the contrary, among LEDs, blue LEDs have good performance and long life, followed by red LEDs, and green LEDs have poor efficiency. If the strengths of both OLED and LED can be organically combined in a light-emitting device, it will be possible to make a long-life, high-efficiency composite lamp. In addition, it can solve the defect that the color temperature and color of OLED white light emitting appliances and LED white light emitting appliances cannot be adjusted in the prior art. Contents of the invention [0003] The object of the present invention is to...
