Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to an LED lamp with a variable lighting range. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is cured onto a support using silver or white glue. Then, silver or gold wires are used to connect the chip to the circuit board. The entire chip is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. Therefore, LED lights have good shock resistance.

[0003] A semiconductor wafer consists of two parts: a P-type semiconductor, where holes are the dominant type, and an N-type semiconductor, where electrons are the dominant type. When these two semiconductors are joined together, they form a PN junction. When current flows through the wafer, electrons are pushed into the P-region, where they recombine with holes and release energy as photons. This is the principle behind LED light emission. The wavelength of the light, which determines its color, is determined by the materials forming the PN junction.

[0004] Initially, LEDs were used as indicator lights for instruments and meters. Later, LEDs of various colors were widely used in traffic lights and large-area displays, generating significant economic and social benefits.

[0005] However, the illumination range of current LED lights is fixed. Some LED lights can be designed to illuminate from a distance, but the illumination range of a well-made LED light cannot be changed. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0006] The purpose of this invention is to provide an LED lamp with a variable illumination range that can control the illumination range of the LED lamp body by changing the concave or convex shape of the mounting surface of the elastic LED beads, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED lamp with variable illumination range, comprising an LED lamp body, a lamp body on the LED lamp body, a mounting bracket inside the lamp body, an air pump, a rectifier, and a built-in power supply on the mounting bracket, a miniature cylinder at the center of the lower surface of the mounting bracket, the air pump and the miniature cylinder being connected by an air guide tube, an elastic LED bead mounting surface at the bottom end of the lamp body, the elastic LED bead mounting surface being fixedly installed to the bottom port edge of the lamp body, and LED beads being evenly distributed inside the elastic LED bead mounting surface;

[0008] The top of the lamp body is equipped with a fixing plate, which is fixedly installed to the top of the lamp body.

[0010] Preferably, the lamp body is cylindrical, and small heat sinks are symmetrically provided on the upper side wall of the lamp body.

[0011] Preferably, the push shaft end of the miniature cylinder is provided with a fixed connector, which is fixedly connected to the center of the upper surface of the elastic lamp bead mounting surface.

[0012] Preferably, the interior of the elastic LED mounting surface is provided with an LED mounting groove, the connection between the LED and the LED mounting groove is provided with sealant, the upper surface of the elastic LED mounting surface is provided with a waterproof connector, and the lower surface of the elastic LED mounting surface is a reflective surface.

[0013] Preferably, the rectifier is provided with an external power supply line, and the other connection end of the rectifier is connected to the built-in power supply.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) A plug is provided at the center of the bottom of the fixed base plate. The plug is embedded, so it can be easily and quickly connected to the power cord during installation, while still ensuring the flatness of the fixed base surface.

[0016] (2) The LED lamp can be fixed to the mounting surface by fixing the base plate, and at the same time, it has a good sealing and protection effect on the lamp body of the LED lamp body;

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: an LED lamp with variable lighting range, including an LED lamp body 1, a lamp body 2 on the LED lamp body 1, and a mounting bracket 6 inside the lamp body 2. The lamp body 2 is cylindrical, and small heat sinks 14 are symmetrically arranged on the upper side wall of the lamp body 2. A temperature sensor is installed on the small heat sink 14. When the temperature sensor on the small heat sink 14 detects that the internal temperature of the lamp body 2 is greater than 70-75℃, the small heat sink 14 is automatically turned on. The blades of the two opposing small heat sinks 14 on the side wall of the lamp body 2 rotate in the same direction. This allows cold air from the outside to be sent into the lamp body 2 while hot air inside the lamp body 2 is expelled, greatly improving the cooling efficiency.

[0026] The mounting bracket 6 is equipped with an air pump 9, a rectifier 10, and a built-in power supply 13. A miniature cylinder 7 is located in the center of the lower surface of the mounting bracket 6. The air pump 9 and the miniature cylinder 7 are connected by an air guide tube. The push shaft end of the miniature cylinder 7 is equipped with a fixed connector 8, which is fixedly connected to the center of the upper surface of the elastic lamp bead mounting surface 3.

[0027] The bottom end of the lamp body 2 is provided with an elastic lamp bead mounting surface 3. The elastic lamp bead mounting surface 3 is fixedly installed with the bottom port edge of the lamp body 2. LED lamp beads 5 are evenly arranged inside the elastic lamp bead mounting surface 3.

[0028] The top of the lamp body 2 is provided with a fixing base plate 4, which is fixedly installed on the top of the lamp body 2. The fixing base plate 4 is disc-shaped, and fixing screw holes are evenly provided inside the fixing base plate 4 near the four edges. A plug 12 is provided in the center of the bottom of the fixing base plate 4. The plug 12 is embedded, which allows for convenient and quick connection to the power cord during installation. At the same time, it is necessary to ensure the flatness of the surface of the fixing base plate 4. The plug 12 is connected with the built-in power supply 13. The fixing base plate 4 can fix the LED lamp to the mounting surface, and at the same time, it also provides good sealing and protection for the lamp body 2 of the LED lamp body 1.

[0029] The interior of the flexible LED mounting surface 3 is provided with an LED mounting groove. The connection between the LED LED 5 and the LED mounting groove is provided with sealant. The upper surface of the flexible LED mounting surface 3 is provided with a waterproof connector 11. The lower surface of the flexible LED mounting surface 3 is a reflective surface, which can greatly improve the light reflection efficiency. Under the drive of the micro cylinder 7, the flexible LED mounting surface 3 can be concave or convex, so that the light illumination range of the LED LED 5 on the flexible LED mounting surface 3 is reduced or expanded.

[0030] The rectifier 10 is equipped with an external power supply line, and the other connection end of the rectifier 10 is connected to the built-in power supply 13. The rectifier 10 rectifies the current stored in the external power supply and the built-in power supply 13, so that the LED lamp body 1 can operate stably for a long time.

[0031] The structure of the LED lamp body 1 is simple, and the illumination range of the LED lamp body 1 can be controlled by changing the concave or convex shape of the elastic lamp bead mounting surface 3.
