From a realistic perspective, although the EU has not allowed the production and import of incandescent lamps of more than 100 watts since 2009, it has so far been easily available from the market. Because according to EU regulations, inventory products can be sold indefinitely. In addition, incandescent lamps can continue to be sold in stores in the name of â€œspecial lighting materialsâ€, but they cannot be placed together with â€œgeneral lighting materialsâ€. In several building materials markets in Vienna, incandescent lamps are still on the original shelves. The seller said that because consumers are worried that they can't buy incandescent lamps in the future, they want to buy more spares, which has led to the recent sales peak of incandescent lamps.
Some critics in Austria pointed out that incandescent lamps should be eliminated naturally through market competition, and administrative measures should not be used. At present, the energy-saving lighting on the market is cold, the shape is single, the price is expensive, and it cannot be dimmed. It is quite difficult to force the consumer to the consumer. In addition, energy-saving lamps are also harmful to the environment. Experts suggest that if you want to save energy, but do not like energy-saving lamps, you can choose LED lighting equipment.
In Austria, energy-saving lamps are not the same as incandescent lamps and are classified as â€œspecial wasteâ€ and must be sent to a small number of designated locations. Consumers also report that the lighting brightness and light color of energy-saving lamps can not meet the needs of home lighting. They believe that energy-saving lamp manufacturers should be encouraged to develop various types of lighting fixtures suitable for consumers' needs through market competition. The use of administrative means to take incandescent lamps can only protect the interests of energy-saving lamp manufacturers and is unfavorable to consumers.
Resistor (Resistor) commonly known as resistance directly in our daily life.It is a current limiting element. When the resistance is connected to the circuit, the resistance value of the resistor is fixed, usually two pins.Fixed resistors are those whose resistances cannot be changed.Resistance variable is called potentiometer or variable resistor.The ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage.Variable resistor for partial pressure.On the exposed resistor body, one or two movable metal contacts are pressed tightly.The contact position determines the resistance between any end of the resistance body and the contact.
