Description

Technical Field

[0001] The utility model relates to the technical field of LED light intensity adjustment, in particular to an LED light source with adjustable light intensity. Background Art

[0002] An LED, or Light-Emitting Diode, is a solid-state semiconductor device that converts electrical energy into visible light. The following is a detailed introduction to LEDs. The heart of an LED is a semiconductor wafer. One end of the wafer is attached to a bracket, with the cathode connected to the cathode and the other connected to the positive terminal of a power source. The entire wafer is encapsulated in epoxy resin. The semiconductor wafer is composed of a P-type semiconductor and an N-type semiconductor, forming a PN junction. When current flows through a wire and acts on the wafer, electrons are pushed into the P region, where they recombine with holes and emit energy as photons. This is how LEDs emit light. The wavelength (and therefore the color) of the light is determined by the material forming the PN junction.

[0003] In different environments, people require different intensities of light sources. Adjusting the light intensity to the appropriate level can reduce the intensity of eye use. Existing LED light adjustment generally uses the size of the current to adjust the brightness of the light source. However, if different currents are used for intensity adjustment for a long time, it will cause irreversible damage to the LED lamp. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides an LED light source with adjustable light intensity, including a translucent lampshade, a card plate fixedly connected to the inner wall of the translucent lampshade, a baffle fixedly connected to the inner wall of the translucent lampshade, a limit plate clamped inside the card plate, a light bar fixedly connected to the surface of the limit plate, a lamp bead fixedly connected to the bottom of the light bar, a welding head fixedly connected to the right end of the light bar, a connecting wire fixedly connected to the inside of the welding head, a fixed sleeve fixedly connected to the inner wall of the translucent lampshade, a micro servo motor fixedly connected to the inside of the fixed sleeve, the output end of the micro servo motor is transmission-connected to a transmission rod, a light shielding plate fixedly connected to the surface of the transmission rod, a rotating shaft fixedly connected to one end of the transmission rod, and a light blocking plate fixedly connected to the inner wall of the translucent lampshade.

[0005] Through the above technical solution, by setting a shading plate, the limit plate at the right end of the light bar is clamped inside the clamping plate, and then the limit plate at the left end of the light bar is placed above the baffle to form an installation of the light bar. When the entire light bar is installed and the light intensity needs to be adjusted during use, the micro servo motor is started, and the micro servo motor drives the transmission rod to rotate, and the rotation of the transmission rod drives the shading plate to rotate. Since the shading plate is located below the lamp beads, when the shading plate rotates, the space for the brightness transmission of the lamp beads will be gradually reduced to adjust the intensity of the light source.

[0006] As a further improvement of the above scheme, the card plate and the baffle are symmetrically and evenly distributed on the inner wall of the translucent lampshade with the top center of the translucent lampshade. There are two limit plates, and the two baffles are symmetrically and evenly distributed at both ends with the top center of the light bar. The two limit plates are respectively clamped on the inside of the card plate and the top of the baffle.

[0007] Through the above technical solution, the light bar is fixed inside the translucent lampshade through the limiting plate.

[0008] As a further improvement of the above solution, the number of the lamp beads is set to be several, and the several lamp beads are evenly distributed on the surface symmetrically with respect to the center of the bottom of the light strip.

[0009] Through the above technical solution, the light source is output through the lamp beads.

[0010] As a further improvement of the above solution, the fixing sleeve is located at the right end of the front inner wall of the translucent lampshade, the transmission rod is located below the light bar, and the diameter of the light shield is greater than the diameter of the light bar.

[0011] Through the above technical solution, the motor is fixed by the fixing sleeve, and the diameter of the light shield is larger than the diameter of the light bar, which can block the light source generated by the lamp beads.

[0012] As a further improvement of the above solution, the rear end of the rotating shaft is fixedly connected to the inner wall of the translucent lampshade, one end of the transmission rod is fixedly connected to the output end of the micro servo motor, and the other end of the transmission rod is fixedly connected to the inside of the rotating shaft.

[0013] As a further improvement of the above solution, there are two light-blocking plates, and the two limiting plates are evenly distributed on the inner wall of the translucent lampshade symmetrically with respect to the center of the top of the translucent lampshade.

[0014] Through the above technical solution, the light source generated by the lamp beads is isolated on the inner wall of the translucent lampshade by setting a light-blocking plate to prevent the light source from leaking out from the inner wall of the translucent lampshade. The light source can only be transmitted through the bottom of the translucent lampshade, and the light shielding plate is used to adjust the intensity of the light source.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model sets a shading plate, connects the limit plate at the right end of the light bar to the inside of the card plate, and then places the limit plate at the left end of the light bar above the baffle to form the installation of the light bar. When the light bar is installed as a whole and the light intensity needs to be adjusted during use, the micro servo motor is then started, and the micro servo motor drives the transmission rod to rotate, and the rotation of the transmission rod drives the shading plate to rotate. Since the shading plate is located below the lamp beads, when the shading plate rotates, the space for the brightness transmission of the lamp beads will be gradually reduced, so as to adjust the intensity of the light source.

[0017] The utility model isolates the light source generated by the lamp beads on the inner wall of the translucent lampshade by arranging a light-blocking plate, thereby preventing the light source from leaking out from the inner wall of the translucent lampshade. The light source can only be transmitted through the bottom of the translucent lampshade, and the light shielding plate is used to adjust the intensity of the light source.

[0027] The card plate 2 and the baffle 3 are symmetrically and evenly distributed on the inner wall of the translucent lampshade 1 with the top center of the translucent lampshade 1. There are two limit plates 4. The two baffles 3 are symmetrically and evenly distributed at both ends with the top center of the light bar 5. The two limit plates 4 are respectively clamped on the inside of the card plate 2 and the top of the baffle 3.

[0028] There are a number of lamp beads 6 , which are evenly distributed on the surface symmetrically around the bottom center of the light strip 5 .

[0029] The fixing sleeve 9 is located at the right end of the front inner wall of the light-transmitting lampshade 1 , the transmission rod 11 is located below the light bar 5 , and the diameter of the light shielding plate 12 is greater than the diameter of the light bar 5 .

[0030] The rear end of the rotating shaft 13 is fixedly connected to the inner wall of the light-transmitting lampshade 1 , one end of the transmission rod 11 is fixedly connected to the output end of the micro servo motor 10 , and the other end of the transmission rod 11 is fixedly connected to the inside of the rotating shaft 13 .

[0031] There are two light blocking plates 14 , and the two limiting plates 4 are evenly distributed on the inner wall of the translucent lampshade 1 symmetrically around the top center of the translucent lampshade 1 .

[0032] The implementation principle of an LED light source with adjustable light intensity in the embodiment of the present application is as follows: when installing the LED light strip 5, first, the limit plate 4 at the right end of the light strip 5 is clamped inside the clamping plate 2, and then the limit plate 4 at the left end of the light strip 5 is placed above the baffle 3 to form the installation of the light strip 5.
