The lighting device disclosed in the embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate and emitting light in at least a first direction; a resin layer sealing the plurality of light emitting devices; and an optical member disposed on the resin layer, wherein the resin layer may include a first light blocking portion integrally formed with the resin layer and having a transmittance lower than that of the resin layer on an emission-side region of each of the plurality of light emitting devices.

A light strip assembly, a backlight module, and a display device are provided. The light strip assembly includes: a light board, provided with at least two different types of light-emitting unit arrays, where each type of light-emitting unit array includes a plurality of light-emitting units, different types of light-emitting units are configured to emit lights with different wavelengths, and wirings of the plurality of light-emitting units of each type of light-emitting unit array are integrated into an outlet terminal; and a control circuit board, provided with at least two connectors, where different connectors are connected to the outlet terminals of the different types of light-emitting unit arrays in one-to-one correspondence to control lighting ratios of the light-emitting units of the different types of light-emitting unit arrays.

Alight source module comprises the light-emitting element, a heat radiator and a diffusion lens. The light-emitting element comprises a substrate and a chip module arranged on the substrate. RGB light mixing units and cold and warm light mixing units of the light-emitting element are concentrically arranged, a plurality of RGB light mixing units and a plurality of cold and warm light mixing units are alternately arranged at intervals, and the plurality of RGB light mixing units and the plurality of cold and warm light mixing units are rotationally symmetrical about the center of the chip module.

Provided is a light fixture comprising: a. plurality of LED light sources, the LED light sources configured to produce differently colored lights; b. LED driver to power the LED light sources, the LED driver comprising a color changing module; c. a controller with two switches, a first switch for manually changing the color of the LED light sources, and a second switch for turning on and off the controller input relating to the color of the LED light sources; wherein when the second switch is in the off position, a switch on a dimmer directly communicates with the driver, the module of the driver automatically (automatic mode) changing the color according to input received from a switch on the dimmer.

The present application provides a light-emitting module, which comprises a light-emitting element and a packaging layer disposed on a substrate, the packaging layer including first and second inclined surfaces disposed on an outer side of the packaging layer from bottom to top, an upper surface of the packaging layer recessed downward corresponding to the light-emitting element, and an optical layer disposed on the upper surface of the packaging layer and extended along the upper surface of the packaging layer to form at least one first reflective surface, wherein the first angle of the first inclined surface is different from the second angle of the second inclined surface, and the at least one first reflective surface is disposed at a third angle.
