[0017] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0018] refer to Figures 1-4 This embodiment provides a multi-adjustable angle LED light, including: a light source board 1, on which two sets of LED light sources and lenses 7 are provided, which are divided into a first LED light source and a second LED light source, and the lenses 7 are divided into a first lens corresponding to the first LED light source and a second lens corresponding to the second LED light source;

[0019] The first lens and the second lens have different light output angles;

[0020] It also includes a switching switch S1, which illuminates the first LED light source and / or the second LED light source when the switching switch S1 is switched to different positions, so as to change the light emission angle of the LED lamp.

[0021] In this embodiment, the switching switch S1 includes a first three-position switch and a second three-position switch. Position 1 of the first three-position switch is connected to the positive electrode of the first LED light source, and position 1 of the second three-position switch is in neutral. Position 2 of the first three-position switch is connected to the positive electrode of the first LED light source, and position 2 of the second three-position switch is connected to the positive electrode of the second LED light source. Position 3 of the second three-position switch is connected to the positive electrode of the second LED light source, and position 3 of the first three-position switch is in neutral.

[0022] The first position switch 2 is connected to the positive terminal of the first LED light source through resistor R1; the second position switch 2 is connected to the positive terminal of the second LED light source through resistor R2. By having the first group of LEDs, the first lens, the second LED light source, and the second lens work simultaneously, and by having R1 and R2 control the proportion of the LED operating current in their respective circuits, the entire lamp can achieve a combined third or more angle values, with the angle value between θ1 and θ2.

[0023] After the above settings, when the switch S1 is in position 1, the first LED light source and the corresponding first lens work independently, and the entire lamp achieves the first angle θ1; when the switch S1 is in position 3, the second LED light source and the corresponding second lens work independently, and the entire lamp achieves the second angle θ2; when the switch S1 is in the middle position 2, the first LED light source, the first lens, the second LED light source, and the second lens work simultaneously, and the entire lamp achieves the third angle θ3, where θ1≤θ3≤θ2. The resistors R1 and R2 control the proportion of the LED operating current in each circuit, allowing the entire lamp to achieve the combined third or more angle values, with the angle value between θ1 and θ2.

[0024] This embodiment also includes a lampshade 2, an aluminum cup 3, a heat sink 4, and a lamp holder 5; the heat sink 4 has a mounting cavity extending through it along the axial direction, and the lamp holder 5 is disposed at one end of the heat sink 4 along the axial direction; the aluminum cup 3 is placed inside the heat sink 4, and the light source plate 1 is fixed on the aluminum cup 3. A lever 6 is disposed on the outside of the side wall of the heat sink 4, which controls the switching switch S1 to different positions. The lampshade 2 is disposed at the other end of the heat sink 4 along the axial direction.

[0025] The aforementioned multi-angle adjustable LED light uses two sets of LED beads and a lens. By selecting the current ratio of the two sets of LED beads through a switch and controlling the power supply, the angle can be any value between angle θ1 and angle θ2. This reduces product costs and makes it easy to produce products with three, five, six, or even more angle settings.

[0026] The above is merely one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. There are many ways to control the current ratio of the two LED beads through switch selection and power control. Using other control methods to control the current ratio of the two LED beads, so that the angle can be any angle value between angle θ1 and angle θ2, does not substantially modify the present invention and constitutes an infringement of the protection scope of the present invention.

[0027] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
