[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] Figures 1-9 As shown, a power tool with lighting function includes a handle 2, a head 1, and a lighting system. The head 1 includes a housing 6, an actuating component 15, and a power component. The power component includes an electric motor assembly mounted on the housing 6. The actuating component 15 is connected to the electric motor assembly, and the electric motor assembly drives the actuating component 15 to perform external operations. A transmission assembly 16 is provided between the electric motor assembly and the actuating component 15, connecting the electric motor assembly and the actuating component 15. The transmission assembly 16 is used for power transmission between the electric motor assembly and the actuating component 15, which is a grinding disc.

[0031] Figure 1 , Figure 2 As shown, the front end of the handle 2 is rotatably connected to the housing 6, and the handle 2 is used for holding and controlling.

[0032] The lighting system includes a control circuit and a lighting device mounted on the housing 6. The lighting device includes several lighting units 11 for lighting. The lighting units 11 are electrically connected to the control circuit. The several lighting units 11 are divided into at least two groups of lighting modules. The control circuit can control the light emission state of each lighting module.

[0033] Preferably, the control circuit can control all lighting modules to be constantly lit, or the control circuit can control some of the lighting modules to be constantly lit, or the control circuit can control different lighting modules to be lit alternately.

[0034] This patent provides multiple lighting modes for the machine tool by setting several lighting units 11 on the housing 6, dividing the lighting units 11 into at least two groups of lighting modules, and controlling the light emission state of each lighting module through a control circuit, so as to meet the needs of different working conditions. Furthermore, by using at least two groups of lighting modules for illumination, the lighting area is increased, the lighting brightness is improved, and the user's vision and operating accuracy are enhanced.

[0035] Preferably, each group of lighting modules emits a different color of light. A control circuit controls the different colored lighting modules to meet the needs of various working conditions. Depending on the working environment and requirements, different lighting modes can be switched via the control circuit.

[0036] For example, in the first scheme, there are 5 lighting units 11. These 5 lighting units 11 are divided into two groups of lighting modules. Three white-light emitting lighting units 11 are combined into one group, and the other two red-light emitting lighting units 11 are combined into another group. The control circuit can realize full-brightness mode, partial-brightness mode, and flashing mode. In full-brightness mode, both groups of lighting modules are lit simultaneously. In partial-brightness mode, only the white-light emitting lighting modules are lit. In flashing mode, the two groups of lighting modules alternately light up and turn off at a frequency of 11Hz. During normal operation, full-brightness mode can be selected to obtain the maximum illumination range and brightness. When it is necessary to observe details, partial-brightness mode can be selected to observe using white light illumination. When it is necessary to draw attention, flashing mode can be selected.

[0037] In another scheme, there are 8 lighting units 11, which are divided into two groups of lighting modules. Four white-emitting lighting units 11 are combined into one group, and the other four yellow-emitting lighting units 11 are combined into another group. The control circuit can realize full-brightness mode, white light mode, and yellow light mode. In full-brightness mode, both groups of lighting modules are lit at the same time; in white light mode, only the white-emitting lighting modules are lit; in yellow light mode, only the yellow-emitting lighting modules are lit. During normal operation, full-brightness mode can be selected to obtain the maximum illumination range and brightness. When it is necessary to observe details, white light mode can be selected to observe using white light illumination. When it is necessary to simulate a daylight environment, yellow light mode can be selected.

[0038] In another scheme, there are 10 lighting units 11, which are divided into three groups of lighting modules. Four white-emitting lighting units 11 are grouped together, three red-emitting lighting units 11 are grouped together, and three blue-emitting lighting units 11 are grouped together. The control circuit can realize full-color mode, white light mode, red light mode, and blue light mode. In full-color mode, all three lighting modules are lit simultaneously; in white light mode, only the white-emitting lighting modules are lit; in red light mode, only the red-emitting lighting modules are lit; and in blue light mode, only the blue-emitting lighting modules are lit. During normal operation, the full-color mode can be selected to obtain the maximum illumination range and brightness. When it is necessary to observe details, the white light mode can be selected; when it is necessary to observe thermal expansion and contraction, the red light mode can be selected; and when it is necessary to observe stress distribution, the blue light mode can be selected.

[0039] Preferably, the lighting unit 11 is an LED lamp, a halogen lamp, or a xenon lamp, such as an LED chip or a COB chip.

[0041] By placing the lighting device inside the housing 5, the size of the machine tool can be effectively reduced, and the convenience of working in narrow spaces can be improved. The use of a transparent housing 5 allows the light from the lighting unit 11 to spread outward better, thereby improving lighting efficiency.

[0042] Preferably, the cover 5 is made of transparent polycarbonate material, transparent PC material, or transparent PMMA material.

[0043] The transmission assembly 16 is installed inside the head shell 3, the actuating component 15 is located at the bottom of the head shell 3, and the handle 2 is rotatably connected to the head shell 3.

[0044] The lighting device is installed on one side inside the housing 5, opposite to one side wall of the housing 5, and the light emitted by the lighting device shines through the opposite side wall. The lighting device can be installed on the side, top, bottom, or other locations inside the housing 5.

[0045] The lighting unit 11 occupies 15%-85% of the area of ​​the side wall of the enclosure 5, and the lighting unit 11 refers to all lighting units 11.
