After years of development, LED lamps of major brands have entered a mature and stable stage. Even the price is not far from the traditional energy-saving bulbs. The most basic LED bulbs are about 100 yuan, compared with traditional bulbs. LED lights have more five characteristics of low temperature, no UV, no blue light, high stability and long life. The competitiveness is greatly increased. What are the benefits of LED lamps? How should we choose? We interviewed designers Zhang Yixin explained it to everyone. At the same time, the designer also reminded everyone that if you want to compare the life of various bulbs, you should calculate it by "time in real use" or "number of switches", and if you want to compare the price, you have to Based on the "same space use ping number".
Five advantages! The advantages of LED lighting for interior decoration are many
1. LED lights are more energy-efficient than traditional energy-saving bulbs, and will not be excessively hot, even if you turn on the lights indoors in summer, you will not feel stuffy.
2. Generally, fluorescent lamps are equipped with ultraviolet rays. Long-term exposure will make the skin black and aging, and it is easy to cause mosquitoes to gather. LED lamps have no such troubles.
3. Good quality LED lamps will completely filter out the blue light in the light by coating excellent fluorescent agents, and the eyes will be more secure for long-term use.
4. The stability of the LED lamp is high, and it is not easy to occur such as the traditional light bulb's light decay, flicker or light color change.
5. Due to the many parts of traditional light bulbs, it is often necessary to replace a small part. The average life of each light bulb is only one to two years. Under normal use conditions, one light bulb can be used up to five. Six years, it is more durable than traditional light bulbs.
Do you understand the basic label of the light bulb?
When purchasing a light bulb, you should first identify the CNS certification mark and the inspection certificate number. If the mark and the certificate number are clearly marked, it is a safe light bulb that is truly certified. In addition, there will be a watt (W) on the package. The values ​​of lumen (lm), voltage (V), color temperature (K), and light decay rate (F), among which the watt representing the power consumption, the lumens representing the brightness, and the color temperature with the most influence style need to be confirmed first. Designers reminded: the higher the wattage, the more power consumption, the higher the lumens, the brighter the lamp, the higher the color temperature, the whiter the light (about 5000K is the color of the sun).
* The key inspection items of the Standards Inspection Bureau of the Ministry of Economic Affairs of Taiwan since 2014/7/1 are as follows:
1.CNS15436 "Stabilizer Built-in Light Emitting Diode Bulb - Safety Requirements"
2. CNS15630 "Integrated Light Bulbs for General Lighting Stabilizers - Performance Requirements"
3. CNS14115 "Resonance Limits and Measurement Methods for RF Disturbance in Electrical Lighting and Similar Equipment"
Key inspection items include temperature and humidity testing, mechanical strength, flame resistance testing of insulating materials, photobiosafety, electromagnetic interference, harmonic distortion, surge protection, luminous flux, luminous efficiency, and lifetime.
Confirm the size, height and style of the space before buying LED lights
Different space environments have different light requirements. First, you should select the required bulb brightness and quantity according to the number of pings. If the indoor space is particularly high, you should also consider this condition. In addition, it is necessary to consider the space style and function. In terms of style, the living room, bedroom and dining table that need to create a warm atmosphere can use the warm yellow light. If you need clear and bright working space, you can choose the white light. However, the designer still emphasizes that there is no certain standard for the choice of lamps. For example, in foreign countries, many standing lights and corner lights are often used in indoor spaces instead of ceiling headlights. In Taiwan, most families prefer the whole house. The feeling of brightness, so the headlights are still mostly based on the ceiling, it is recommended that you still have to choose according to the habits and needs of personal use.
Flexible mixing and matching of different characteristics in space
The lamps commonly used at home can be divided into four types: ceiling lamps, xenon lamps, laminate lamps, and reading lamps. Each has different characteristics and can be flexibly used according to environmental requirements. Basically, a variety of light sources can be mixed and installed in one space. Functionality, such as the installation of neon lights and accent lighting at the dining table. When the whole family is having dinner together, they can turn on the bright neon lights, and when they drink a little wine before going to bed at night, they can switch to accent lighting. The light creates a situation of taste.
1. Ceiling light: Like a large disc hanging directly on the ceiling, the market can also find a number of special style lamp holders with decorative style.
2. Xenon lamp: The installation of Xenon lamp requires woodwork and ceiling, and it is often used as a regional key lighting atmosphere light. It is often used to illuminate the main wall or hanging paintings.
3. Laminate lamp: The installation of the laminate lamp also needs woodwork. Although it is more troublesome, the advantage is that the lamp can be hidden to make the space more concise and degenerate, and the light source of the laminate lamp is average, scattered and soft, and installed in the center. Or the corner can be.
4. Reading light: Because of the strong functional requirements, the brand selection of the light bulb is very important; in addition, the designer also reminds that if you want to install the reading light on the bedside, remember to lock the wall but have the arm bracket to extend the light. The style avoids the light from being directly hit by the wall, and is easily blocked by the pillow, the bed board or the body, and the effect is not good.
Use special luminaires to enhance the use of functions, and play by the way!
In addition to the common lamps on the market, many large brands have also introduced lamps for special situations. For example, a light bulb that can be wirelessly controlled by a mobile phone or a lamp can change three colors and switch in an on/off mode. You can immediately select the light that meets the current demand, or the ultra-thin LED laminate lamp, which is only 0.5 cm thick, and can be directly attached to the under the laminate, under the bed or the cabinet of the flow table, and can satisfy the small space. The light requirements of the area; these luminaires that emphasize the use of function are good choices for making life more convenient and fun!
High frequency board dielectric material has the following characteristics
1. It has the characteristics of small signal transmission loss, short transmission delay time and small signal transmission distortion.
2, has excellent dielectric properties (mainly DK, DF). Moreover, this dielectric property (DK, DF) maintains its stability under environmental changes in frequency, humidity, and temperature.
3. High-precision control with characteristic impedance (Zo).
4, has excellent heat resistance (Tg), processability and adaptability.
