Detailed Description

In order to more clearly describe the technical contents of the present utility model, the following is further described in connection with specific embodiments.

As shown in fig. 1 to 5, an embodiment of the adjustable automotive ceiling lamp of the present utility model is shown. The ceiling lamp comprises a lampshade and a rear cover 8, wherein an inner space is formed after the lampshade and the rear cover 8 are installed. The internal space is provided with a circuit board 7, a lens 3 and a light source, wherein the light source consists of a cold white light LED 5 and a warm white light LED 6, the light source is integrated on the circuit board 7 towards the direction of the lampshade, and the lens 3 is arranged on the circuit board 7 and covers the light source, so that light rays emitted by the light source pass through the lampshade through the lens.

In the adjustable automobile ceiling lamp, light rays emitted by the cold white light LED 5 and the warm white light LED 6 firstly pass through the lens 3, and the lens 3 uniformly diverges the light rays emitted by the cold white light LED 5 and the warm white light LED 6 to the inner surface of the mask 1; the mask 1 evenly diverges incident light on the inner surface, and realizes even light mixing of the cold and warm color temperature.

The lampshade comprises a diffusion mask 1, light rays emitted by the light source penetrate through the diffusion mask through the lens, and the diffusion mask can be formed by injection molding of conventional diffusion materials. The lampshade comprises a decorative ring 2 and a shell 4, one end of the shell 4 is connected with the mask 1 through the decorative ring 2, the other end of the shell 4 is connected with a rear cover 8, and the circuit board 7 is pressed on the end of the shell through the rear cover. The mask and the decorative ring (see fig. 4), the decorative ring and the shell (see fig. 3), the lens and the circuit board, and the back cover and the shell (see fig. 5) can be connected in a snap-fit manner.

The circuit board comprises a luminous flux adjusting module, and the luminous flux adjusting module adjusts the luminous flux by adjusting the currents of the cold white light LED and the warm white light LED.

Specifically, the luminous flux adjustment module can adjust the luminous fluxes emitted by the respective cold white LEDs 5 and warm white LEDs 6 by adjusting the currents thereof. Wherein, the color temperature can be adjusted from cold white to warm white or from warm white to cold white by adjusting the proportion of luminous fluxes of the cold white LED and the warm white LED; by adjusting the total luminous flux emitted by the cool white LEDs and the warm white LEDs, a low to high or high to low adjustment of the brightness can be achieved.

In this specification, the utility model has been described with reference to specific embodiments thereof. It will be apparent, however, that various modifications and changes may be made without departing from the spirit and scope of the utility model. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
