Some knowledge about table lamp
Table lamps are a common household appliance that we frequently use to protect our eyes from strain. A good table lamp should have adjustable light intensity to ease eye fatigue. Fluorescent lamps are the recommended light source for table lamps because they can protect eyes and save energy. When selecting a table lamp, it is essential to consider several factors.
There are four types of light sources for writing table lamps: incandescent lamps, halogen lamps, fluorescent lamps, and LED lights. Each type has its own advantages and disadvantages, and different people may prefer different light colors and brightness levels. To illuminate the desktop effectively, the light source for a writing table lamp should be installed horizontally or downward.
When purchasing a writing table lamp, it is important to check its optical performance as well as other features, such as pull, adjust, shake, and touch. "Pull" refers to the power cord plug being securely connected to the lamp chamber. "Adjustment" involves locking the lamp in the desired working position without making any sound. "Shaking" is checking whether the lamp is stable or prone to overturning. "Touch" is touching the lamp shade and other parts that may become hot during use to avoid accidental scalding.
The lighting angle and range of a table lamp are also important considerations. The light should be level with the line of sight, and the illumination range should cover the entire working area without being too scattered or concentrated. The illumination of the light should also be consistent and not flickering.
