Detailed Description
The following describes the indoor uniform illumination lamp of the automobile in detail with reference to the accompanying drawings and the specific embodiments.
Fig. 1 is a schematic view of an indoor uniform illumination lamp structure of an automobile according to an embodiment of the invention. Referring to fig. 1, the invention provides a light-homogenizing illuminating lamp structure in an automobile, which mainly comprises: the lamp comprises a lamp holder (1), a bulb support (2), a bulb (3) and a lampshade (4). The bulb support (2) is arranged at the center of the lamp holder (1), and an umbrella-shaped light shield (201) is arranged below the bulb support (2). The bulb (3) is arranged on the bulb support (2), wherein the umbrella-shaped light shield (201) can shield and reflect light emitted by the bulb and pointing to the direction of the lampshade (4).
Preferably, only one bulb support (2) and one bulb (1) are installed in the embodiment, the LED bulb is selected for the bulb (3), the bulb support (2) is formed by welding two mutually insulated metal columns and a PCB circuit board, and two electrodes of the LED bulb are respectively connected with the metal columns. Two metal posts penetrate through the base (1) and are then connected with power supply electrodes. Thus, the bulb support (2) not only plays a role of installing and supporting the bulb (3) and the umbrella-shaped light shield (201), but also plays a role of a conductive electrode.
