Description

Technical Field

[0002] With the popularization and development of electric technology, lighting fixtures have become an indispensable tool in people's daily lives. Traditional incandescent and energy-saving lamps have been gradually replaced by high-efficiency and energy-saving LED lighting fixtures. However, existing LED lighting fixtures still have certain limitations in terms of functionality and applicability. Existing high-power bulbs used for lighting are usually made of glass, such as the bulb disclosed in Chinese patent CN222503570U. These bulbs are fragile and easily damaged by impacts. Most LED bulbs have a fixed brightness, and the luminous power of the bulb is controlled at a specified value through components such as constant current drivers. For example, household lighting bulbs typically have a power of 6W-9W: approximately 450-800 lumens, while larger ones are 10W-13W: approximately 800-1100 lumens. These types of bulbs usually cannot flexibly adjust the power and light intensity according to actual needs, making it difficult to meet the needs of diverse scenarios, such as creating a home atmosphere, commercial lighting, or lighting control in special occasions. In view of this, the inventors have made a new invention. Utility Model Content

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1 to 6 This utility model will be described in detail.

[0028] The present invention relates to a sealed and waterproof high-power anti-drop light bulb, comprising a bulb shell 1 and a light-emitting component 2. The bulb shell 1 is made of plastic and is provided with a snap 11. The snap 11 is the open end of the bulb shell 1 and protrudes by a certain length. The light-emitting component 2 is inserted into the bulb shell 1 through the snap 11.

[0029] The light-emitting component 2 is provided with a plug seat 21 and an LED light group 3. The front end of the plug seat 21 is provided with a core post 211 that can be inserted into the blister pack 1. The LED light group 3 is fixedly connected to the core post 211. The rear end of the plug seat 21 can be connected to the bayonet 11 and is provided with a receiving cavity 22. The receiving cavity 22 has an open end. An electrical connection plate 4 is provided inside the receiving cavity 22. The inner wall of the receiving cavity 22 has a pre-reserved sealing glue position 221 near the open end. The sealing glue position 221 is filled with sealant to airtightly isolate the electrical connection plate 4 from the outside. The plug seat 21 and the core post 211 are made of plastic, just like the blister pack 1. They are not only drop-proof and impact-resistant, but also lightweight and low in manufacturing cost. After the electrical connection plate 4 is placed into the receiving cavity 22, it will sink to a certain depth, so that the electrical connection plate 4 is located at or passes through the sealant position 221. After the receiving cavity 22 is filled with sealant, the opening end of the receiving cavity 22 can be sealed, preventing water vapor from entering the blister shell 1 through the wire hole 23 described below, thus achieving good waterproof effect.

[0030] The plug seat 21 is provided with a wire hole 23 that can accommodate multiple wires. The wires of the LED light group 3 are electrically connected to the electrical connection plate 4 through the wire hole 23. Specifically:

[0031] The plug seat 21 is provided with a positioning block 25, and there are two wire holes 23 that pass through the positioning block 25. The LED light group 3 is provided with at least multiple wires, and the multiple wires are distinguished as positive and negative. The positive and negative wires of the LED light group 3 pass through the two wire holes 23 respectively and are electrically connected to the electrical connection plate 4 in the accommodating cavity 22.

[0032] The wire hole 23 can be squeezed and narrowed to fix the wires of the LED light assembly 3 relative to the wire hole 23. For example... Figure 6 As shown, the positioning block 25 compresses the wire holes 23 on both sides corresponding to the wire holes 23, thus fixing the wires of the LED light group 3 relative to the wire holes 23. During the production and assembly of the bulb, the positioning block 25 is compressed to a certain extent using stamping equipment or other mechanical extrusion equipment, which reduces the inner diameter of the wire holes 23, fixing the wires of the LED light group 3 inside and securing them to prevent the wires from continuously shifting within the wire holes 23 and causing the LED light group 3 to loosen, thereby improving stability.

[0033] The electrical connection board 4 is equipped with an expansion capacitor 41 and a control chip 42. The control chip 42 is an integrated IC chip with a built-in voltage reading module and at least one sampling resistor connected to or integrated within it to detect current and voltage. The expansion capacitor 41 is an external large-capacity capacitor of the electrical connection board 4. The electrical connection board 4 is provided with a first wire 43 and a second wire 44 for connecting to an external power supply. The control chip 42 and the expansion capacitor 41 can adjust the output power of the LED group 3 according to the voltage input to the first wire 43 and the second wire 44, thereby changing the light emission of the LED group 3. Specifically, the first wire 43 and the second wire 44 are directly or indirectly connected to a transformer circuit, such as a voltage controller or other circuit control device. The control chip 42 and the expansion capacitor 41 can adjust the output power of the LED group 3 according to the voltage input to the first wire 43 and the second wire 44, thereby changing the light emission of the LED group 3. This bulb is installed in a lamp holder. If the lamp holder is connected to a constant voltage circuit, the output power of this bulb will also be constant. If the lamp holder has a voltage transformation function or is connected to a variable voltage circuit, the control chip 42 can identify the voltage and adjust the output power of the LED group 3. This structure is suitable for scenarios where the size of the light is centrally controlled, such as living rooms, lobbies, photography studios, construction sites, etc. Compared with LED bulbs of the same size on the market, the output power of this bulb can be centrally controlled and changed, thereby increasing or decreasing the lighting brightness.

[0034] A lamp holder 13 is provided on the outside of the bayonet 11. The first wire 43 and the second wire 44 are electrically connected to the two electrodes of the lamp holder 13, respectively. The lamp holder 13 is a threaded lamp holder 13 or a clip-on lamp holder 13. By connecting the lamp holder 13 to the lamp socket, the first wire 43 and the second wire 44 are connected to form a circuit, so that the LED lamp group 3 emits light.

[0035] The bulb shell 1 is filled with an inert gas. Preferably, helium is used as the inert gas in this design. Filling the bulb shell 1 with helium can dissipate heat and prevent fogging inside the bulb shell 1, thus ensuring the light transmittance of the bulb shell 1 and further improving the brightness of the bulb.

[0036] The bayonet 11 has a threaded portion 12 on its exterior, and the plug seat 21 has a stepped portion 24 that abuts against the port of the bayonet 11. In special application scenarios, such as when multiple bulbs are connected in series or parallel as a light string, the first wire 43 and the second wire 44 can be connected to the circuit of the light string. Then, by screwing the bulb shell 1 onto the lamp holder of the light string, the bulb can be installed and fixed without the need for a metal lamp head 13. Through the limiting of the port of the bayonet 11 and the stepped portion 24, the other side of the stepped portion 24 will abut against the lamp holder on the light string wire to fix the position of the light-emitting component 2 and make the plug seat 21 tightly connected to the bayonet 11, preventing moisture from entering the bulb shell 1 through the gap of the bayonet 11, and further improving the waterproof performance.

[0037] The LED light group 3 is provided with multiple LED light strips 31, and third wires 32 and fourth wires 33 connecting the light strips. The third wire 32 passes through the wire hole 23 and is electrically connected to the electrical connection plate 4. The fourth wire 33 connects multiple LED light strips 31 in series. The end of the core post 211 is provided with a positioning groove 212 for positioning the fourth wire 33. The two ends of the LED light strips 31 are close to the end of the core post 211 and the plug 21, respectively. The fourth wire 33 is used for electrical connection between LED light strips 31, so that multiple LED light strips 31 are connected in series. At least two third wires 32 are provided, and they pass through the wire holes 23 at different positions. The two third wires 32 are connected to the electrical connection plate 4 to form the positive and negative circuits of the LED light group 3. The combination of multiple LED light strips 31 can improve the brightness of the light and reduce the load-bearing capacity of a single LED light strip 31, avoid overcurrent or overheating of the LED light strips 31, and improve the service life.

[0038] The end of the core post 211 is provided with a protruding bump 213, which can be heat-melted and deformed. Compared with glass lamp holders on the market, the plug seat 21, core post 211, and bulb shell 1 of this utility model are all made of plastic, which is lightweight, low-cost, and shockproof. During the production and assembly of the bulb, after the fourth wire 33 is placed into the wire guide groove 212, the bump 213 is partially heat-melted using a high-temperature tool. The bump 213 is partially melted and deformed to block or fill the wire guide groove 212, thereby fixing the fourth wire 33 and thus fixing the LED lamp assembly 3. Production and assembly are convenient.

[0039] As another embodiment of the LED light group 3, the LED light group 3 is further provided with two groups, each group of the LED light group 3 is provided with two LED light strips 31, one end of the LED light strip 31 is provided with a third wire 32 connected to the electrical connection plate 4, and the other end of the LED light strip 31 is provided with a fourth wire 33 for electrically connecting the two LED light strips 31. The wire connection structure of the LED light group 3 is as follows: one end of one LED light strip 31 is connected to one third wire 32, one end of the other LED light strip 31 is connected to another third wire 32, and the other ends of the two LED light strips 31 are connected in series through the fourth wire 33. In this structure, the two third wires 32 of the first group of LED light group 3 are electrically connected to the two third wires 32 of the second group of LED light group 3 respectively. After the two third wires 32 of the first group of LED light group 3 are electrically connected to the electrical connection plate 4, the second group of LED light group 3 can also be powered.

[0040] The LED light group 3 is provided with multiple LED light strips 31, which are arranged equidistantly around the core post 211. Each LED light strip 31 is inclined relative to the core post 211. See also Figure 3 The LED light group 3 has two sets, and two wiring slots 212 are provided. The fourth wire 33 of the LED light group 3 is fixed in different wiring slots 212. The fourth wire 33 is bent. The third wire 32 passes through the wire hole 23 and then bends. The bent part of the third wire 32 and the corresponding end of the fourth wire 33 are offset to each other, with a relative angle between 20° and 90°. This structure makes the LED light strip 31 tilted, and when viewed from the side of the bulb, multiple LED light strips 31 intersect. This greatly reduces the impact of light being blocked by other LED light strips 31 when the LED light strip 31 is emitting light, thereby improving the brightness of the bulb. At the same power, this bulb has higher brightness. For example, the brightness of a conventional LED bulb with a power of 6 watts is usually 400-800 lumens. The brightness of this bulb can reach 800-1100 lumens at a power of 6 watts. Even when connected to a constant voltage circuit, this bulb has higher brightness, expanding its application range and allowing it to be used in open spaces and other places.

[0041] Furthermore, the expansion capacitor 41 is disposed on the upper side of the electrical connection plate 4, and a supporting wire 45 is provided between it and the electrical connection plate 4. The control chip 42 is disposed on the lower side of the electrical connection plate 4. The expansion capacitor 41 is an external capacitor, which will generate heat during use. In this solution, the supporting wire 45 is a rigid electrical connection wire, which can not only be used to electrically connect the expansion capacitor 41 and the electrical connection plate 4, but also support the expansion capacitor 41, so that there is a gap between the expansion capacitor 41 and the electrical connection plate 4, avoiding direct contact between the expansion capacitor 41 and the electrical connection plate 4.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
