Classification and characteristics of lamps
Let me talk about the choice of table lamps, mainly to look at the quality and production process of electronic parts. Generally, the quality of electronic parts of small manufacturers' desk lamps is poor, and the level of production technology is low. Therefore, consumers should choose table lamps produced by large manufacturers. Generally, the living room, the bedroom, etc. are decorated with table lamps, and the work table and the learning table are equipped with energy-saving eye protection lamps, but the energy-saving lamps cannot be dimmed. The sixth downlight 1. The characteristic downlight is generally installed on the ceiling of the bedroom, living room and bathroom. This invisible luminaire embedded in the ceiling, all light is projected downwards and is a direct light distribution. Different reflectors, lenses, blinds, and bulbs can be used to achieve different lighting effects. The downlight does not take up space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, try to install multiple downlights to reduce the pressure on the space. Second, the main problem of selecting the downlight is on the lamp socket. Some of the lamps of the branded downlight are not resistant to high temperature and are easily deformed, which may cause the bulb to not be screwed down. Now, all lamps can only be sold after 3C certification. Consumers should choose 3C-certified downlights. Seventh, spotlights. The spotlights can be placed around the ceiling or the upper part of the furniture. They can also be placed inside walls, wall skirts or In the baseboard. The light directly shines on the objects that need to be emphasized, in order to highlight the subjective aesthetic effect, to achieve the artistic effect of focusing, unique environment, rich layers, rich atmosphere and colorful. The lighting light line is soft and graceful, which can play a leading role in the overall lighting, and can also partially illuminate the atmosphere. Second, the choice of spotlights is divided into low-voltage and high-voltage. Consumers should choose low-voltage spotlights, which have a longer life and higher light efficiency. The light effect of the spotlight is reflected by the power factor. The greater the power factor, the better the light effect. The power factor of the ordinary spotlight is about 0.5, the price is cheap, and the power factor of the high-quality spotlight can reach 0.99, and the price is slightly expensive. Eighth, Yuba I. Features Yuba according to the way of heating, the light bulb infrared heating bath and the heater to warm the bathroom, the market is mainly the bulb infrared heating bath. According to the function, there are three-in-one Yuba and two-in-one Yuba. The three-in-one Yuba has lighting, heating and exhausting functions; the two-in-one Yuba has only lighting and heating functions. According to the installation method, the dark-filled Yuba, the wall-mounted Yuba, the wall-mounted Yuba, the concealed Yuba are more beautiful, and the Mingyu Yuba is directly installed on the top. Generally, the wall-mounted Yuba can not be selected by using the concealed and wall-mounted Yuba. The Yuba from the regular manufacturers generally pass the standard full inspection of the hot and cold alternating performance test, sprayed at 4 ° C under ice, subjected to instant hot and cold tests, and then use the explosion-proof glass to ensure absolute safety in the bath. Second, the choice of Yuba heating is as long as the light is warm, and the size of the room is not large, mainly depends on the skin temperature of Yuba. Yuba has 2, 3, and 4 bulbs. Generally, there are 2, 3 bulbs for heating rooms, and 4 bulbs for rooms without heating. Standard Yuba bulbs are all 275 watts, but low-quality bulbs are slow to heat up and cannot reach the temperature specified by 275 watts. When choosing Yuba, consumers can stand 1 meter away from Yuba, open the Yuba, feel the heating speed and temperature of Yuba, and the temperature is faster and the temperature is higher. Ninth, energy-saving lamps I. Features The brightness and life of energy-saving lamps are superior to those of ordinary incandescent bulbs, especially in terms of power saving. Energy-saving lamps are U-shaped, spiral-shaped, petal-shaped, etc., with power ranging from 3 watts to 40 watts. The prices of energy-saving lamps of different models, different specifications and different origins vary greatly. Energy-saving lamps can be installed in lamps such as downlights, chandeliers, and ceiling lamps. Energy-saving lamps are generally not suitable for use in high temperature and high humidity environments. Energy-saving lamps should be avoided in bathrooms and kitchens. Second, choose to buy energy-saving lamps to the guaranteed lighting market, to choose a well-known brand, and confirm that the product packaging is complete, the logo is complete. The life of the energy-saving lamp, color rendering, and correct installation position are usually explained on the outer package. The energy-saving lamp is divided into two kinds of halogen powder and three base color powders. The comprehensive performance of the three-base color powder is better than that of the halogen powder. Some merchants sell the halogen powder as a three-base color powder to deceive consumption.
