Description

Technical Field

[0001] The utility model relates to UVB light source technology, in particular to a lamp with adjustable UVB irradiation value. Background Art

[0002] UVB light source technology is very suitable for pet breeding, especially for providing a wide range of uniform UVB light source irradiation for reptiles. At present, different irradiances can be produced through different formulas and spraying ratios. There are many different UVB lamp products on the market, including UVB2.0, UVB5.0, UVB10.0, and UVB15.0.

[0003] For example, a UVB ultraviolet lamp disclosed in a Chinese patent with authorization announcement number CN202564182U includes a lamp tube made of quartz glass or high boron glass, the inner wall of which is coated with a layer of ultraviolet powder, which can emit ultraviolet light with a wavelength of 275 to 320 nm. It is used to irradiate animals, which can not only promote their metabolism and accelerate their growth rate, but also promote calcium absorption. However, the lamp disclosed in this patent is the same as most products on the market. It is impossible to switch the UVB mode. If you want to switch, you can only achieve the needs of UVB10.0 and UVB5.0 by replacing 10.0 or 5.0 lamps or lamps. If users are required to purchase different lamps and frequently replace lamps to achieve the needs of UVB10.0 and UVB5.0, users need to have the corresponding professional skills to operate. Obviously, this will consume users' resources, bring cumbersome operations, increase the burden on users and bring a bad experience.

[0004] Based on the above analysis, the present invention proposes a lamp with adjustable UVB irradiance value in combination with actual application needs to solve the problem of being unable to switch between UVB10.0 and UVB5.0. Utility Model Content

[0005] In view of the above defects, the present invention provides a lamp with adjustable UVB irradiance value, thereby overcoming the disadvantage that existing UVB lamps on the market are generally unable to switch between UVB10.0 and UVB5.0 modes.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The power supply EMI and rectification and filtering unit includes a varistor RV for absorbing surge voltage, a safety capacitor C1 for filtering in the anti-interference circuit, and a common-mode inductor L1 for suppressing common-mode interference signals in the circuit;

[0009] Start the self-excited oscillation unit, which is connected to the power supply EMI and rectification and filtering unit, including the high-frequency oscillation switch transistor Q1, the high-frequency oscillation switch transistor Q2, and the power-on starting bidirectional trigger diode DB1;

[0010] The overload protection unit is connected to the power supply EMI and the rectifier filter unit, and the startup self-excited oscillation unit respectively. The power overload protection unit is provided with a protection bidirectional trigger diode DB2;

[0011] The boost unit is connected to the starting self-excited oscillation unit and the power overload protection unit respectively. The boost unit includes a plurality of boost inductors and a bypass switch SW connected to the boost inductors. The inductive impedance of the boost inductors of the boost unit is adjusted by switching the bypass switch to achieve power change, thereby switching between UVB10.0 and UVB5.0 modes of the lamp.

[0012] Furthermore, the self-excited oscillation starting unit further includes a high-frequency voltage transformation unit;

[0013] Furthermore, one end of the high-frequency oscillation switch transistor Q1 is connected to a diode D11, and the diode D11 is connected to a power-on starting bidirectional trigger diode DB1;

[0014] Furthermore, the power overload protection unit further includes a locked protection state thyristor and a transistor Q4, wherein the transistor Q4 is connected to the protection bidirectional trigger diode DB2.

[0015] For an implementable high-frequency transformer unit, when configuring the circuit, it may include a resistor R14, a component T1, a resistor R13, and a component T2.

[0016] For the implemented startup self-excited oscillation unit, when configuring the circuit, one end of the high-frequency oscillation switch transistor Q1 can be connected to the diode D12, capacitor C10, and resistor R14 in sequence, and the resistor R14 can be connected to the component T1. One end of the high-frequency oscillation switch transistor Q2 can be connected to the diode D13, capacitor C11, and resistor R13 in sequence, and the resistor R13 can be connected to the component T2.

[0017] For the lamp, pressing the bypass switch SW left or right is used to switch the lamp between the UVB10.0 desert mode and the UVB5.0 rainforest mode.

[0018] The technical solution of the utility model is configured with a starting self-excited oscillation unit, a power overload protection unit, and a boost unit, and the inductive impedance of the boost inductor of the boost unit is adjusted by switching the switch of the boost unit to achieve power change, thereby realizing one-key switching between UVB10.0 and UVB5.0 modes through the power adjustment of the product, and meeting the demand for switching between UVB lamp 10.0 and 5.0 application modes without replacing the lamp or lamp tube.

[0028] The technical solution of the lamp with adjustable UVB irradiance value implemented by the utility model aims to solve the problem that conventional UVB lamps cannot switch between UVB10.0 and UVB5.0.

[0029] like Figure 1-3As shown, the lamp with adjustable UVB irradiance implemented by the present invention has a frequency-dependent impedance because impedance is a physical quantity that reflects the degree of resistance to alternating current in a circuit. Therefore, when a component in a circuit has a large impedance, the circuit has a certain resistance to the flow of current. Impedance determines the circuit's response characteristics to AC voltage. Circuits with different impedance values have different responses to voltage. This response characteristic can be used to design filters and frequency selection circuits. When connecting the corresponding circuit units, Figure 2 and Figure 3 The connection points A1, A2, and A3 marked in each figure are connected correspondingly, forming Figure 1 The overall circuit diagram is shown.

[0030] like Figure 2 The circuit shown in the figure shows the lamp with adjustable UVB irradiance implemented in the present invention. It includes the lamp's power supply EMI and rectifier filter unit. A varistor RV is connected to one end of the AC 220V power supply for absorbing surge voltages. Adjacent to it are a safety capacitor C1 for filtering in the anti-interference circuit and a common-mode inductor L1 for suppressing common-mode interference signals in the circuit, thereby suppressing EMI electromagnetic interference and conducted radiation. Within the power supply EMI and rectifier filter unit, which includes the varistor, safety capacitor, and common-mode inductor, an inductor L2 is also connected. One end of inductor L2 is connected to capacitors C2 and C4. Capacitor C2 is connected to capacitor C3, while capacitor C4 is connected to diodes D9 and D8, respectively.

[0031] like Figure 4 As shown, the lamp with adjustable UVB irradiance value implemented by the present invention, the power supply EMI and rectification and filtering unit implemented above are connected to the starting self-excited oscillation unit, which includes two high-frequency oscillation switch transistors, namely Figure 4 In the circuit shown for components Q1 and Q2, one end of the high-frequency oscillation switching transistor Q1 is sequentially connected to a diode D12, a capacitor C10, and a resistor R14, with the resistor R14 being connected to component T1. The high-frequency oscillation switching transistor Q2 is sequentially connected to a diode D13, a capacitor C11, and a resistor R13, with the resistor R13 being connected to component T2, thereby forming a high-frequency voltage transformation unit comprising resistor R14, component T1, resistor R13, and component T2. Accordingly, the emitter end of the implemented high-frequency oscillation switching transistor Q1 is sequentially connected to a resistor R11 and a diode D11, with the diode D11 being connected to the power-on bidirectional trigger diode DB1.

[0032] like Figure 5As shown, the lamp with adjustable UVB irradiation value implemented by the present invention, the power supply EMI and rectification and filtering unit, and the starting self-excited oscillation unit implemented above are all connected to the power overload protection circuit unit, and the power overload protection circuit unit is provided with a protection bidirectional trigger diode DB2, and the protection bidirectional trigger diode DB2 is connected to the resistor R19, the resistor R18, the resistor R17, and the resistor R16 in sequence; at the same time, the power overload protection circuit unit includes a locked protection state thyristor and a transistor Q4, wherein the transistor Q4 is connected to the protection bidirectional trigger diode DB2.

[0033] like Figure 6 As shown, the lamp with adjustable UVB irradiance value implemented by the present invention has the above-implemented starting self-excited oscillation unit and power overload protection circuit unit connected to the boost circuit unit. This boost circuit unit includes a boost inductor L1, a boost inductor L2, and a boost inductor L3. A bypass switch SW is provided between the inductor L2 and the inductor L3 for switching between UVB10.0 desert mode and UVB5.0 rainforest mode. This bypass switch SW is connected to the lamp.

[0034] like Figure 7-8 The figure shows one of the external shapes of the lamp with adjustable UVB irradiance implemented by the utility model. A switch (i.e., bypass switch) is provided at one end of the lamp. Taking into account the above disadvantages, the present patent can achieve a good function switching effect through improvement. During operation, the inductance impedance of the boost inductor of the boost circuit unit is adjusted by switching the switch to achieve power change, thereby achieving one-touch switching between UVB10.0 and UVB5.0 modes through the power adjustment of the product, and meeting the switching needs of 10.0 and 5.0 application modes without replacing the lamp or lamp tube.

[0035] In the description of this specification, the terms "connection", "setting", "having", etc. are understood in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and technical effects. It can also be an integral connection or a partial connection. As in this example, for ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] The above description of the embodiments is intended to facilitate understanding and application by ordinary technicians in this technical field. It is obvious that those familiar with the technology in this field can easily make various modifications to these examples and apply the general principles described herein to other embodiments without having to engage in creative work. Therefore, the scope of protection of the present utility model is not limited to the above circumstances.
