The structural design of tungsten wire has a significant impact on the efficiency of bulbs. The following is a detailed analysis of this impact from several aspects:
- The influence of tungsten wire thickness
Resistance and current: The thickness of tungsten wire directly affects the resistance value of the bulb. Thicker tungsten wires have lower resistance, so higher current is required to achieve the same luminous effect, which means higher power consumption. On the contrary, thinner tungsten wires have greater resistance and can emit light at lower current. But too thin tungsten wires may cause the bulb to overheat or even burn out.
Luminous efficiency: Tungsten wires with moderate thickness can avoid excessive power consumption and overheating problems while ensuring sufficient luminous efficiency. Therefore, in bulb design, the thickness of tungsten wires needs to be weighed to optimize the luminous efficiency.
- The influence of tungsten wire length
Voltage and power: Longer tungsten wires require higher voltage to drive sufficient current, resulting in higher power consumption.
Thermal deformation and stability: Longer tungsten wires are more prone to thermal deformation during the luminous process, which affects the stability of the bulb. Shorter tungsten wires can better maintain their shape and stability, which helps to improve the luminous efficiency and life of the bulb.
- The influence of tungsten wire purity
Conductivity and thermal stability: High-purity tungsten wires have better conductivity and thermal stability, which can improve the luminous efficiency and life of the bulb.
Light and color stability: Tungsten wires containing impurities may cause the bulb to produce unstable light and color during the light-emitting process. High-purity tungsten wires can ensure the stability and consistency of light and improve the lighting quality of the bulb.
- The influence of tungsten wire shape and arrangement
Shape optimization: By optimizing the shape of tungsten wires (such as spiral, double spiral, etc.), the surface area of tungsten wires can be increased and the luminous efficiency can be improved. At the same time, this shape design also helps to dissipate heat and extend the life of the bulb.
Arrangement: Reasonable arrangement of tungsten wires inside the bulb can ensure uniform distribution of light and reduce light loss. In addition, by adjusting the spacing and angles between tungsten wires, the luminous efficiency and lighting effect of the bulb can be further optimized.
