As can be seen from the above description, the design of the first inclined guiding surface and the second inclined guiding surface enables that when the reflector2is pressed in towards the second diffusion cover12and the first diffusion cover11is pressed in towards the reflector2, the abutting structure moves smoothly along the inclined guiding surface, and finally clamps into the position.

In some embodiments, further comprising a plastic shell4, the plastic shell4is clamped to an end of the second diffusion cover12away from the first diffusion cover11.

The material of the bulb shell1is selected according to the actual design requirements, including glossy glass, frosted glass, PC (Polycarbonate), PP (Polypropylene), etc., for example, glass is selected for the bulb shell1in this embodiment. Meanwhile, the material transmittance and color of the bulb shell1are selected according to the actual design requirements, for example, the transmittance comprises 98%, 95% and other values, and the color comprises blue, red and the like. The color is achieved by applying a light diffusing agent inside the material, for example by applying a light diffusing agent inside the glass to achieve the corresponding color, or by using different PC colors.

In some optional implementations, the first diffusion cover11and the second diffusion cover12are independently designed; for example, the first diffusion cover11is made of transparent glass, with a light transmittance of 98%; the second diffusion cover12is made of light yellow PP, with a light transmittance of 90%. The thickness of the first diffusion cover11ranges from 0.4-5 mm; as shown inFIG.3, the thickness of the top of said first diffusion cover11is less than the thickness of the bottom connection position; and the thickness of the first diffusion cover11is set according to the actual light transmission requirements: for example, the thickness of the design can be 0.4 mm, 0.5 mm, 1 mm, 2 mm, 5 mm, and so on, and in the actual design process, if a larger light transmittance is required, the thickness is reduced; if a smaller light transmittance is required, the thickness is increased. Likewise, the thickness of the second diffusion cover12can also be adjusted according to the actual application. The reflector2is further provided with a bending angle, the bending angle is the angle between the reflector2and the light source plate3, and the bending angle is adjusted according to the brightness and darkness of the actual required light output, e.g. reducing the height of the reflector2and the bending angle when there is a need to reduce the range of the light output of outer-circle light source32.

In this way, there is no need to set up a relevant connection structure again between the reflector2and the light source plate3according to the actual needs. In an optional embodiment, the reflector2is connected to the light source plate3by means of locking screws.

The heat sink is arranged in the plastic shell4and is located on the side of the light source plate3away from the first diffusion cover11.

In at least one embodiment, the light input end of the reflector2is connected with the light source plate3through a screw lock. A more reliable form of screw locking can be used to ensure the connection and fixation of the reflector2with the light source plate3, which improves the integrality; meanwhile, the relative arrangement of the inner-circle light source31and the outer-circle light source32with the corresponding portions of the reflector2is ensured.

Working principle of the present disclosure: when used as the main lighting function, the inner-circle light source31emits light, and the light rays pass through the light input end, the light output end and the first diffusion cover11of the reflector2in turn, and emit from the front of the whole lamp; when used as the small nightlight function, the outer-circle light source32emits light, and the light rays reflect from the outer wall of the reflector2and pass through the second diffusion cover12, and emit from the side of the whole lamp.

In the assembly of the whole lamp, the reflector2and the first diffusion cover11, the reflector2and the second diffusion cover12, the reflector2and the light source plate3, and the second diffusion cover12and the plastic shell4are all in the form of a quick clamping design, which is convenient for assembly and maintenance.
