[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Provide a floodlight with adjustable light angle, such as Figures 1 to 5 As shown, including:

[0023] A shell 1, a light-emitting lens 2 is arranged at the front end of the shell, an adjustment switch is arranged at the rear end of the shell, and a radiator 3 is arranged inside the shell; a light board 4 is arranged at the front end of the radiator, and the light board is arranged toward the light-emitting lens; the rear end of the radiator is connected to one end of the transmission structure, and the other end of the transmission structure is connected to the adjustment switch; when the adjustment switch is turned on or off, the radiator is displaced relative to the light-emitting lens.

[0024] The shape of the shell can be flexibly set, for example, in the shape of a bullet head, the adjustment switch is arranged at the head of the bullet head, and the light output lens is arranged at the tail of the bullet head.

[0025] The light-emitting lens is made of PC material with good light transmittance and UV resistance, and its focal length and shape are designed as a convex lens according to the requirements of the light-emitting angle.

[0026] The shape of the heat sink can be flexibly selected. It is arranged inside the housing and connected to the transmission structure. The light board arranged on the heat sink is a light-emitting component. The LED and the LED light board are fixed on the heat sink. The number and position of the LED lights are designed according to actual needs. At the same time, the PCB board connected to the light board and the power supply are arranged in the housing. It is a conventional design and will not be repeated here.

[0027] The adjustment switch can be a button, a knob or other methods. The transmission structure can be a screw, a stepper motor, a slide, etc. The function of the transmission structure is to connect the adjustment switch and the radiator. Under the action of the adjustment switch, the radiator is pushed back and forth to change the distance between the light board and the light-emitting lens, thereby changing the light-emitting angle. The light-emitting angle ranges from 30° to 110°.

[0028] In one implementation, the adjustment switch is a knob 5, and the transmission structure is a focus screw 6. When the knob is turned, the heat sink moves back and forth in the horizontal direction of the focus screw. That is, the transmission structure is composed of a precision screw rod to ensure the stability and accuracy of the knob rotation, while facilitating the durability and maintenance convenience of the transmission mechanism.

[0029] Furthermore, a reflector cup 7 is provided inside the housing, which wraps the light board and abuts against the back of the light-emitting lens. Preferably, the upper end of the reflector cup is wider than the lower end, and transitions from the wider end to the lower end with an inwardly concave arc surface, that is, the shape and angle of the reflector are designed according to the adjustment range of the light-emitting angle to ensure that the light can be evenly distributed at different angles to avoid light spots and dark areas.

[0030] Furthermore, a color temperature adjustment module and a power adjustment module 8 for controlling the light board are also arranged inside the housing, and a window corresponding to the switch for operating the color temperature adjustment module and the power adjustment module is opened on the surface of the housing; the window is covered with a waterproof cover 9. The color temperature adjustment module can change the color temperature of the LED lamp by adjusting the power supply demand, and the power adjustment module can change the brightness of the LED lamp by adjusting the current. The waterproof cover plays the role of shielding, waterproofing and dustproofing.

[0031] Furthermore, a 360° rotatable light shield 10 is provided on the housing near the light-emitting lens, and the light shield is used to adjust the light-emitting degree. Specifically, the light shield is fixed to the bracket 12 and connected to the housing through a waterproof ring 11.

[0032] The above is an explanation of the floodlight with adjustable light-emitting angle of the utility model, which is used to help understand the utility model; however, the implementation method of the utility model is not limited to the above-mentioned embodiments, and any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the utility model should be equivalent replacement methods and are included in the protection scope of the utility model.
