[0002] An HID ballast is an electronic ballast designed specifically for HID (High Intensity Discharge) xenon lamps to control the startup and stable operating current of HID lamps. However, there are significant differences between LED lamps and HID lamps in terms of the light-emitting principle, electrical characteristics, and usage requirements. Therefore, there is usually no LED lamp that is directly compatible with an HID ballast.

[0003] However, in the field of automotive modification or lighting upgrade, there may be situations where it is necessary to replace the original vehicle's HID headlights with LED headlights. Such LED lamps are designed to replace traditional HID lamps, such as metal halide lamps or high-pressure sodium lamps, to provide higher energy efficiency, longer service life, and better lighting quality. At this time, although the LED lamp cannot directly use the HID ballast, it can be modified or replaced through the following several methods.

[0004] Using an LED dedicated driver: An LED lamp requires a dedicated driver (also known as an LED power supply or an LED constant current source) to provide stable current and voltage to ensure the normal operation and long life of the LED lamp. Therefore, when replacing the HID headlights with LED headlights, a driver matching the LED lamp needs to be installed.

[0005] Circuit modification: Due to the different electrical characteristics of HID lamps and LED lamps, it may be necessary to modify the overall circuit to adapt to the use of the LED lamp. This includes changing the interface of the wiring harness, adjusting the voltage and current of the circuit, etc.

[0006] The above methods all require additional modification or assembly of external components when replacing HID lamps with LED lamps and cannot be directly replaced. Therefore, it is necessary to design an LED lamp that can be directly compatible with an HID ballast.

HID Ballast is an electronic ballast designed for HID lamps, used to control the start-up and stabilize the working current of HID lamps. However, there are significant differences between LED lamps and HID lamps in terms of light-emitting principles, electrical characteristics and usage requirements, so LED lamps cannot directly replace HID lamps. The support base 6 with a driving circuit is compatible with most HID Ballasts, and the bulb base 10 is compatible with most conventional lamp holders, and can be directly installed without adapters.

[0019] As a further improvement of the present utility model, the lampshade 1 is a glass cylinder as a whole, the top of the upper end is a hemisphere, and the lower end is connected with the bulb base 10 in an interlocking manner. The support ring 2 is a metal ring, which is formed by bending the upper end of the support column 7 into a ring shape. The filament frame is composed of two upper and lower base rings, the upper end is the first base ring 4, and the lower end is the second base ring 5. The first base ring 4 is a complete metal circular ring, and the first base ring 4 is provided with a fixed beam 11 passing through the center of the circle; the second base ring 5 is composed of a positive half ring and a negative half ring, and the positive half ring and the negative half ring are not directly connected; the fixed beam 11 is welded and fixed to the support column 7 at the center of the first base ring 4, the positive half ring is welded and fixed to the first support beam 8, and the negative half ring is welded and fixed to the second support beam 9. Such a connection structure design has sufficient structural strength and stability, and is convenient for production and manufacturing, and the welding connection method is also easy to assemble.

[0020] As a further improvement of the present invention, the filament sheet 3 is a long sheet structure, the filament sheet 3 is arranged vertically, the upper end is welded to the first base ring 4, and the lower end is welded to the second base ring 5. Compared with traditional lamps and traditional LED light sources, such a filament sheet 3 structure has higher luminous efficiency, energy saving and environmental protection, and longer life; the welded connection mechanical structure has stable performance, strong earthquake resistance, and is easy to install.

[0021] As a further improvement of the present utility model, a drive circuit is provided inside the support base 6. The drive circuit is directly connected to the lamp base 10. At the same time, the drive circuit is connected to the filament holder through the first support beam 8 and the second support beam 9. The positive pole of the drive circuit is connected to the positive half-ring through the first support beam 8, and the negative pole is connected to the negative half-ring through the second support beam 9. The filament sheet groups on the positive half-ring and the negative half-ring are connected in series. The filament sheets 3 within the filament sheet group on the positive half-ring are connected in parallel with each other, and the filament sheets 3 within the filament sheet group on the negative half-ring are connected in parallel with each other. LED lights require a dedicated driver (also known as an LED power supply or an LED constant current source) to provide stable current and voltage to ensure the normal operation and long lifespan of the LED lights. Therefore, when replacing an HID lamp with an LED lamp, a driver matching the LED lamp needs to be installed. The drive circuit enables this product to be compatible with the ballasts of most HID lamps, providing stable current and voltage without the need to rewire the circuit, and can directly replace traditional gas discharge light sources such as fluorescent lamps, high-pressure mercury lamps, and sodium lamps. At the same time, the drive circuit can provide OTP and OVP circuit protection functions. OTP over-temperature protection is an electronic protection function used to protect the circuit and equipment from damage caused by high temperatures. When the temperature of the circuit or equipment rises above a preset threshold, the over-temperature protection will be automatically triggered, and the temperature will be controlled to drop by cutting off the power supply or reducing the power, etc., to prevent further heating and damage. OVP over-voltage protection is used to prevent the circuit and equipment from being damaged due to excessive input voltage. When the voltage exceeds the preset level, the over-voltage protection will cut off the power supply or suspend the output, thereby protecting the subsequent circuit from damage. The support beams play the role of a support structure and also conduct current, eliminating the redundant design of the current circuit while ensuring the structural stability and strength, making the structure simpler, the production cost lower, and the manufacturing and installation more convenient.

[0022] When installing each component, first fixedly connect the lamp base 10 and the support base 6, and then install the support column 7, the first support beam 8, and the second support beam 9 on the support base 6. Subsequently, weld and fix the positive half-ring of the second base ring 5 to the first support beam 8, and the negative half-ring to the second support beam 9. Then weld and fix the fixed beam 11 of the first base ring 4 to the support column 7. At this time, the overall installation of the filament holder is completed, and the welding of the filament sheets 3 can begin. After the welding of the filament sheets 3 is completed, bend the upper end of the support column 7 into a ring to form the support ring 2, and sleeved the whole lampshade 1 outside the lamp core, and embed the lower end into the lamp base 10 to complete the installation. The entire installation process is convenient and concise, and easy to implement.

[0023] In use, this product can be directly used to replace traditional gas discharge light sources such as fluorescent lamps, high-pressure mercury lamps, and sodium lamps, and can be compatible with most HID lamp ballasts without the need to re-transform the circuit. The driving circuit provided inside the support base 6 can be compatible with the HID lamp ballast to provide stable current and voltage for the LED filament sheet group; after the circuit is turned on, the current stabilized by the driving circuit flows from the first support beam 8 to the positive half-ring, and the positive half-ring supplies power to the filament sheet 3 on the positive half-ring as the positive electrode. The current then flows to the first base ring 4, and then flows out from the second support beam 9 through the filament sheet 3 welded on the negative half-ring and returns to the lamp base 10 to form a loop. The filament sheet group on the positive half-ring and the filament sheet group on the negative half-ring are connected in series, and the filament sheets 3 in the filament sheet group on the positive half-ring are connected in parallel with each other, and the filament sheets 3 in the filament sheet group on the negative half-ring are connected in parallel with each other. Using LED lights to design and replace traditional HID lights, such as metal halide lamps or high-pressure sodium lamps, can provide higher energy efficiency, longer service life, and better lighting quality.

The support base 6 with a driving circuit can be compatible with most HID ballasts, and at the same time, the lamp base 10 is compatible with most conventional lamp sockets and can be directly installed without a adapter.

[0025] As a further improvement of the present utility model, the lampshade 1 is a glass cylinder as a whole, the top of the upper end is a hemisphere, and the lower end is connected with the bulb base 10 in an interlocking manner.

The driving circuit makes this product compatible with most of the Ballasts of HID lamps, provides stable current and voltage, and does not require re-construction of the circuit. It can directly replace traditional gas discharge lamp light sources such as fluorescent lamps, high-pressure mercury lamps, and sodium lamps.
