Due to the heat dissipation problems of LED filament lamps, many manufacturers will reduce the wattage of LED filament lamps and reduce the heat generated when LED filament lamps are lit, but the relative brightness will also decrease. Due to the heat dissipation of the LED filament, the entire lamp assembly cannot increase the total wattage, but the market believes that ordinary light bulbs should become the main lighting source and the brightness should be around 1000 lumens. At present, the brightness of some LED incandescent lamps on the market is about 400 lumens, so the current LED incandescent lamps can only be used as decorative lighting, not as the main lighting.

When the current of the led filament light bulb passes through the filament (tungsten filament, the melting point is more than 3000 degrees Celsius), heat is generated. The spiral filament continuously gathers heat, making the temperature of the filament above 2000 degrees Celsius. When the filament is in an incandescent state, it looks like red. The iron can shine like a light. The higher the temperature of the filament, the brighter the light emitted. ) Voltage range: Rated voltage + 10% -20% (2) Power range: Rated (nominal) power + 5% -10%.

The top of the lighthouse is designed with a lid with a handle, which is distinguished by different colors, which can easily distinguish different kinds of spices, and also makes it easier to pick and place the lid of the tank and not easy to fall off. The condiment pot is hollow grouting process, fired at 1280-1300 degrees Celsius high temperature, the color is warm and bright, the edges are smooth and smooth, and it will not scratch the skin. The reinforced porcelain is durable and suitable for kitchen use.

The driving power of three kinds of LED filament bulbs, the current mainstream without disconnection switch constant current driving power supply, the resistance-capacitance buck power supply to be eliminated, the emerging high-voltage linear constant current driving power supply. The general parameters of the driving power of filament lamp mainstream products 1. Candle lamp power: 2W, 3W, 4W, output voltage DC150V, output current 10-12MA, 14-15MA, 20-22MA; 2. Bulb lamp power: 2W, 4W , 6W, 8W, output voltage DC150V, output current 10-12mA, 22-24mA, 33-36mA, 44-48mA.
