Embodiment Construction
[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0019] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a light emitting device. The light emitting device comprises a shell capable of transmitting light, an LED panel and an LED module; the LED panel and the LED module are accommodated in an accommodating cavity in the axial direction of the accommodating cavity in sequence; the LED panel is towards the top end of the shell; and the LED module includes multiple sets of LED light emitting devices spaced in the peripheral direction of the shell and towards the outer side of the shell. The light emitting device further comprises a control circuit board; each set of LED light emitting devices have different color temperatures; and the control circuit board is respectively connected with the LED panel and the multiple sets of LED light emitting devices for respectively controlling working states of the LED panel and the multiple sets of LED light emitting devices. The LED panel and the LED module can respectively emit light towards the frontal surfaces and the side surfaces of the light emitting devices, that is, the light is emitted out from the top sides and the peripheral sides of the light emitting devices; the LED panel and the different sets of LED light emitting devices are controlled to emit light; and mixed light is used for achieving different color temperature requirements to form different atmospheres. Compared with single control of multiple LED modules in the prior art, the light emitting device is simple in structure, low in cost and high in intelligence.
Description
technical field [0001] The invention relates to the technical field of lighting devices, in particular to a lighting device. Background technique [0002] Due to its small size, low driving voltage and no harmful substances such as mercury, LED has become an emerging light source for energy saving and environmental protection. In recent years, with the improvement of LED chip technology, the luminous efficiency of LED has been continuously improved. At the same time, the manufacturing cost of LED is also decreasing continuously, and its application range has expanded from early outdoor lighting to commercial lighting and general lighting, making semiconductor lighting the development trend of today's lighting technology. [0003] With the improvement of people's living standards, people's demand for lighting fixtures is no longer a single lighting mode, but they are more pursuing quality life. For example, ceiling lamps, ceiling lamps, grille lamps and other lamps with var...
