Example Embodiment
[0029] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show part of the structure related to the present invention, but not all of the structure.
[0030] figure 1 It is a schematic diagram of the luminous brightness and luminous efficiency of an existing light-emitting device. Such as figure 1 As shown, the abscissa is the luminous brightness, and the ordinate is the luminous efficiency. Curve 01 is a schematic diagram of the relationship between the luminous brightness and luminous efficiency of the existing light-emitting device. According to the curve 01, it can be seen that the luminous efficiency of the light-emitting device is different at different luminous brightness. Especi...
