Description

Technical Field

[0001] The utility model belongs to the technical field of lighting products, and particularly relates to an LED lamp. Background Art

[0002] The so-called LED lamps, as the name implies, refer to lamp products that use LED (Light-emitting Diode) technology as the main light source. LED is a solid-state semiconductor component that uses the forward flow of current to the semiconductor pn junction coupling, and then the negatively charged electrons and positively charged holes separated in the semiconductor combine with each other to produce photon emission. Different types of LEDs can emit light of different wavelengths, from infrared to blue light, and from purple to ultraviolet light. The new development in recent years is to apply fluorescent powder on blue LEDs to convert blue LEDs into white LED products. This operation generally requires a driver circuit (LED Driver) or a power supply (Power Supply). The main function of the driver circuit or power supply is to convert AC voltage into DC power, and at the same time complete the voltage and current that match the LED to drive the matching components.

[0003] LED lamps are small in size, light in weight, and are encapsulated with epoxy resin. They can withstand high-intensity mechanical shock and vibration, are not easy to break, and have a long brightness decay period, so their service life can be as long as 50,000-100,000 hours, far exceeding the 1,000 hours of traditional tungsten filament bulbs and 10,000 hours of fluorescent tubes. Since the service life of LED lamps can reach 5 to 10 years, it can not only greatly reduce the cost of lamp replacement, but also because of its characteristic of being driven by extremely small current to emit light, under the condition of the same lighting effect, the power consumption is only half of that of fluorescent tubes, so LED also has the advantages of saving electricity and energy.

[0004] An LED lamp is just a light-emitting element. To make it emit light, it needs to be connected to a power source. Today's portable LED lamps are powered by cylindrical batteries. During installation, the positive and negative poles of the cylindrical batteries are sometimes installed in reverse. Reversely installed cylindrical batteries can damage LED lamps.

[0041] The following is combined with Figures 1 to 8 The utility model is further described in detail, but it is not intended to limit the utility model.

[0042] An LED lamp 1 includes a reflector 11 and a base 12, the reflector 11 and the base 12 are screwed, the base 12 includes a first base body 121 and a second base body 122, the diameter of the second base body 122 is smaller than that of the first base body 121, a positioning portion 123 is provided between the first base body 121 and the second base body 122, a first insulating member 13 is provided on one side of the base 12, a first through hole 131 is provided in the middle of the first insulating member 13, an elastic member 14 is provided between the base 12 and the first insulating member 13, one end of the elastic member 14 abuts against the positioning portion 123, and the other end of the elastic member 14 abuts against the first insulating member 13.

[0043] Specifically, the base 12 and the reflector 11 are used to install the LED lamp bead 162 and protect the LED lamp bead 162 to prevent the LED lamp bead 162 from being damaged. When the LED lamp 1 in the present application is connected to the battery, one end of the positive electrode of the battery abuts against the first insulating member 13. The first insulating member 13 prevents other parts of the battery except the positive electrode from contacting the base 12, causing the LED lamp 1 to short-circuit. The positive electrode of the battery contacts the base 12 through the first through hole 131. The first base 12 corresponds to the positive electrode of the battery. When the battery is installed, the battery squeezes the elastic member 14. The elastic member 14 contracts under force and applies reverse pressure to the battery, making the battery more firmly installed and preventing the battery from being disconnected from the base 12. Since the positive pole of the battery protrudes from the end face of the battery, the positive pole of the battery can protrude from the first insulating member 13 and be connected to the base 12. If the battery is installed in the opposite direction, since the end opposite to the positive pole of the battery is a plane and an insulating member is provided between the battery and the base 12, the battery cannot contact the base 12, so a circuit loop cannot be formed, and the LED lamp 1 will not illuminate, thereby preventing the battery from being placed upside down and damaging the circuit board 164.

[0044] At the same time, in this embodiment, the diameter of the second seat body 122 is the same as the inner diameter of the elastic member 14. The elastic member 14 is sleeved on the second seat body 122. The second seat body 122 guides the elastic member 14 and can also fix the elastic member 14.

[0045] The first insulating member 13 is provided with a slot 132 , which is engaged with the end of the elastic member 14 . The engagement between the slot 132 and the elastic member 14 prevents the first insulating member 13 from falling off, causing the battery to directly contact the conductive member 21 .

[0046] In some embodiments, a receiving cavity 15 is provided between the reflector 11 and the base 12, a light-emitting component 16 is arranged in the receiving cavity 15, a second insulating member 17 is provided between the light-emitting component 16 and the receiving cavity 15, the second insulating member 17 is sleeved on the light-emitting component 16, the light-emitting component 16 includes a first wire 161 and an LED lamp bead 162, a second through hole 124 is provided at the bottom of the base 12, the first wire 161 is led out from the second through hole 124, and the reflector 11 is provided with a third through hole 111, and the third through hole 111 is provided corresponding to the LED lamp bead 162.

[0047] Specifically, the accommodating cavity 15 is used to accommodate the light emitting component 16. In this embodiment, the reflector 11 and the base 12 are both metal structures. The direct contact between the light emitting component 16 and the base 12 will cause leakage. Therefore, a second insulating member 17 is arranged between the light emitting component 16 and the base 12. The second insulating member 17 covers the other surfaces of the light emitting component 16 except the upper surface, so as to insulate the light emitting component 16. At the same time, the second insulating member 17 is a rubber structure. The second insulating member 17 can fill the gap between the light emitting component 16 and the accommodating cavity 15 to prevent the light emitting component 16 from shaking. In addition, since the base 12 is a metal structure, the light emitting component 16 is prevented from making hard contact with the base 12, which may cause damage to the light emitting component 16.

[0048] In this embodiment, two first wires 161 are provided, which are respectively connected to the positive and negative electrodes of the light-emitting component 16. The light-emitting component 16 is electrically connected to the battery through the first wires 161. The battery supplies power to the light-emitting component 16 through the first wires 161. The two first wires 161 are led out to the outside through the second through holes 124 to be connected to the battery.

[0049] In this embodiment, the reflector 11 and the base 12 are used to provide all-round protection for the light-emitting component 16 to prevent damage to the light-emitting component 16, and the third through hole 111 is arranged corresponding to the LED lamp bead 162. After the light-emitting component 16 is connected to the battery, the LED lamp bead 162 lights up, and the light emitted by the LED lamp bead 162 is emitted to the outside through the third through hole 111, thereby producing a lighting effect.

[0050] In this embodiment, the second insulating member 17 is provided with a through hole 171 corresponding to the first wire 161 , and the first wire 161 passes through the through hole 171 .

[0051] In some embodiments, the light-emitting component 16 also includes a mounting plate 163 and a circuit board 164, the circuit board 164 and the mounting plate 163 are connected by a second wire 165, the LED lamp bead 162 is arranged on the mounting plate 163, the mounting plate 163 and the circuit board 164 are arranged overlappingly, and a third insulating member 18 is arranged on the side of the mounting plate 163 away from the circuit board 164, and a through hole 181 is arranged on the third insulating member 18, and the through hole 181 is arranged corresponding to the LED lamp bead 162.

[0052] Specifically, first, the LED lamp bead 162 will generate heat when it is lit, and the circuit board 164 will also generate heat when working. Separating the LED lamp bead 162 and the circuit board 164 can prevent their heat from being too concentrated, causing damage to the circuit board 164 or the LED lamp bead 162. At the same time, separating the LED lamp bead 162 and the circuit board 164 in the light-emitting component 16 can greatly save space. Since the space of the accommodating cavity 15 is limited, if the LED lamp bead 162 and the circuit board 164 are set as one body, the space occupied by the circuit board 164 is extremely large, which is not conducive to installing the circuit board 164 into the accommodating cavity 15. Separating the circuit board 164 and the LED lamp bead 162 and arranging them in an overlapping manner can reasonably use the space.

[0053] A plurality of control elements are disposed on the circuit board 164 , and the circuit board 164 is connected to the LED lamp bead 162 via the second wire 165 , so that the LED lamp bead 162 can be effectively controlled via the circuit board 164 .

[0054] In this embodiment, the LED lamp bead 162 is arranged on the mounting plate 163, and the connection solder joint between the circuit board 164 and the mounting plate 163 faces the reflector 11. Therefore, a third insulating member 18 is arranged between the mounting plate 163 and the reflector 11 to prevent the connection solder joint from contacting the reflector 11, thereby causing the LED lamp 1 to leak. At the same time, the third insulating member 18 fills the space between the mounting plate 163 and the reflector 11 to prevent the LED lamp bead 162 from shaking due to the shaking of the mounting plate 163, thereby preventing the third through hole 111 from damaging the LED lamp bead 162, thereby further protecting the LED lamp bead 162. The through hole 181 on the third insulating member 18 is used to avoid the LED lamp bead 162. When the LED lamp bead 162 is turned on, its light diffuses to the outside through the through hole 181 and the third through hole 111.

[0055] In some embodiments, there is a transition cavity 125 between the accommodating cavity 15 and the second through hole 124 . The transition cavity 125 has a large opening and a small opening. The large opening is arranged toward the accommodating cavity 15 , and the small opening is arranged toward the second through hole 124 .

[0056] Specifically, in the present embodiment, the transition cavity 125 is a parabola, and the large opening of the transition cavity 125 faces the accommodating cavity 15. When the light-emitting component 16 is installed in the accommodating cavity 15, the first guide converges along the inner wall of the transition cavity 125 toward the small opening and the second through hole 124. The provision of the transition cavity 125 simplifies the installation of the light-emitting component 16, and the transition cavity 125 serves to guide the direction of the first wire 161.

[0057] In some embodiments, a fourth insulating member 19 is sleeved on the first conductive wire 161 .

[0058] Specifically, since the first wire 161 is an important line connecting the battery and the light-emitting component 16, the first wire 161 is also conductive, and the base 12 is a metal structure, which cannot prevent the first wire 161 from contacting the base 12 and causing leakage of the base 12. The fourth insulating member 19 is sleeved on the first wire 161 to prevent the first wire 161 from contacting the base 12, thereby protecting the LED lamp 1 and the user at the same time.

[0059] In some embodiments, the reflector 11 has a first end 112 and a second end 113, and the distance from the third through hole 111 to the first end 112 is smaller than the distance from the third through hole 111 to the second end 113;

[0060] Specifically, in the present embodiment, the third through hole 111 is infinitely close to the LED lamp bead 162 , and the LED lamp bead 162 is limited by the third through hole 111 , so that the LED lamp bead 162 is restricted in the third through hole 111 to prevent it from being displaced.

[0061] In some embodiments, a focusing portion 114 is arranged between the second end 113 and the third through hole 111. The focusing portion 114 is a parabola. The focusing portion 114 includes a cone tip and a cone end. The cone tip is arranged toward the third through hole 111, and the cone tip is located at the center of the third through hole 111, and the cone end is arranged toward the second end 113.

[0062] Specifically, in this embodiment, the focusing portion 114 between the second end portion 113 and the third through hole 111 is a parabola, and the cone tip is aligned with the LED lamp bead 162 in the third through hole 111. When the LED lamp bead 162 is turned on, the focusing portion 114 reflects and concentrates the light generated by the LED lamp bead 162 to prevent the light from escaping and causing low light intensity, further improving the brightness of the light, and at the same time concentrating the light in the same area, so that the illumination brightness of the LED lamp 1 in this application is higher.

[0063] In some embodiments, the third through hole 111 is disposed at the center of the reflector 11 .

[0064] Specifically, the third through hole 111 is arranged at the center of the reflector 11, so that the LED lamp bead 162 is also placed in the center of the reflector 11. The LED lamp bead 162 is arranged in the center of the reflector, so that the light of the reflector 11 is better concentrated, and the irradiation distance and irradiation brightness of the light are improved.

[0065] In some embodiments, a fifth insulating member 20 is disposed in the second through hole 124, and the fifth insulating member 20 includes a first part 201 and a second part 202, the diameter of the second part 202 is larger than the diameter of the first part 201, the first part 201 is tightly fitted with the second through hole 124, the second part 202 is in contact with the end of the base 12 provided with the second through hole 124, the diameter of the second part 202 is larger than the diameter of the second through hole 124, the first part 201 and the second part 202 are integrally arranged, and the fifth insulating member 20 is provided with a fourth through hole 203, and the first wire 161 is led out from the fourth through hole 203.

[0066] Specifically, in this embodiment, the first guide is provided with two wires, namely, a positive wire and a negative wire, and both the positive wire and the negative wire are led out of the second through hole 124. The contact between the positive wire and the negative wire will cause a short circuit in the circuit board 164, so the positive wire or the negative wire needs to be separated. In this embodiment, the positive wire is separated separately, and the positive wire is placed in the fourth through hole 203. Since the negative wire base 12 is connected in specific use, the base 12 is the negative pole of the LED lamp 1 in this application, so it is necessary to In order to separate the positive electrode wire and prevent the positive electrode wire from contacting the base 12 and causing a short circuit, the first part 201 is placed in the second through hole 124, and the fifth insulating member 20 is fixed by the first part 201. The diameter of the second part 202 is not only larger than the diameter of the first part 201, but also larger than the diameter of the second through hole 124. The fifth insulating member 20 is limited by the second part 202 to prevent the fifth insulating member 20 from being placed entirely in the second through hole 124, which makes it impossible to remove the fifth insulating member 20.

[0067] In this embodiment, the fourth through hole 203 passes through the first portion 201 and the second portion 202 .

[0068] In some embodiments, a conductive member 21 is disposed in the fourth through hole 203, and the conductive member 21 includes a first conductive portion 211 and a second conductive portion 212. The first conductive portion 211 is disposed in the fourth through hole 203, and the second conductive portion 212 contacts the end of the second portion 202. The positive electrode wire contacts the conductive member 21, and the positive electrode wire is placed between the second conductive portion 212 and the second portion 202. The first conductive portion 211 is tightly fitted with the fourth through hole 203.

[0069] Specifically, in this embodiment, the first conductive portion 211 of the conductive member 21 is placed in the fourth through hole 203 and is in contact with the positive wire. Therefore, the conductive member 21 can be considered to be the positive electrode of the LED lamp 1 in this application. At the same time, the conductive member 21 is fixedly connected to the fifth insulating member 20 through the first conductive portion 211, and the diameter of the second conductive portion 212 is larger than the diameter of the fourth through hole 203. The second conductive portion 212 is used to limit the entire conductive member 21 to prevent the entire conductive member 21 from being placed in the fourth through hole 203.
