LED Spotlight

LED spotlight which is the most energy-saving and environmental protection product at present. More and more lamps are made with LED as the light source, among which the most highly praised is led spotlights. 1.The LED spotlight can be driven by low-voltage DC: it has the advantages of small load and weak interference, and has low requirements for the use environment. 2. LED spotlight can better control the composition of luminous spectrum, so it can be well used for local or key lighting in museums and exhibition halls. 3. The luminous directivity of LED spotlights is very strong: the brightness attenuation is much lower than that of traditional light sources, and the price of LED spotlights is civilian. 4. The response time of LED spotlight is very fast: at the microsecond level, as long as the switch is on, it will light up immediately without delay and flicker. 5. The light energy concentration of LED spotlight is very high: it is concentrated in a small wavelength window and has high purity. 6. The service life is very long, generally between 50000-100000 hours, because LED is a semiconductor device. Even frequent switching will not affect the service life. 7. Good environmental protection. The LED spotlight does not need to add "Mercury" in the production process, nor does it need to be inflated. It does not need a glass shell. It has good impact resistance, good seismic resistance, is not easy to break, and is easy to transport. It is very environmentally friendly. It is called "green energy". The price of LED spotlight is civilian. 8. Energy saving. The spectrum of LED spotlight is almost concentrated in the visible frequency band, and its luminous efficiency can reach 80 ~ 90%. It is generally believed that energy-saving lamps can save 4 / 5 of energy, which is a great innovation, but led spotlights can save 1 / 2 of energy than energy-saving lamps, which is a greater reform of solid-state light sources. Led spotlights are mainly used for decoration, commercial space lighting and architectural lighting.

LED Downlight

LED downlight is a kind of lighting fixture embedded in the ceiling. Led downlight is a directional lighting fixture. Only its opposite side can receive light. The beam angle belongs to spotlight, with concentrated light and strong light dark contrast. It highlights the illuminated object, with high lumen, which sets off the quiet environmental atmosphere. Features of LED downlight: keep the overall unity and perfection of architectural decoration without damaging the setting of lamps. The light source is hidden inside the architectural decoration without exposure and glare. The visual effect of people is soft and uniform. Downlights and spotlights are confused by many people. They don't know the difference between these two types of lamps, where they should be applied to the home, and what the effect of application is different. In short, downlight is a kind of lamp with more condensing property than ordinary surface mounted lamps, which is generally used for general lighting or auxiliary lighting. Spotlight is a kind of highly focused lamp. Its light irradiation can specify a specific target. It is mainly used for special lighting, such as emphasizing a very interesting or innovative place. From the application position, downlights are generally installed in the ceiling. Generally, the ceiling needs to be more than 150mm before installation. Of course, downlights also have external type. It is a good choice to install downlights in areas without ceiling lights or chandeliers. The light should be softer than spotlights. Spotlights can generally be divided into track type, point hanging type and embedded type. Spotlights generally have transformers, but some do not have transformers. Embedded spotlights can be installed in the ceiling. Spotlights are mainly used in places that need to be emphasized or expressed, such as TV walls, hanging paintings, jewelry, etc. they can play light rhyme to enhance the effect.

LED Track Light

LED track light is a track lamp with LED as the light source, alias: LED rail light. It is a kind of track lamp, which is widely used in shopping malls (clothing stores, furniture stores and other brand stores), automobile display, jewelry, star hotels, brand clothing, high-end clubs, Bo cultural relics exhibition hall, chain shopping malls, brand business hall, professional window, counter and other key lighting places. Led track lamp takes LED as the light source. LED light source is a cold light source, no radiation, no heavy metal pollution, pure color, high luminous efficiency, low-frequency flashing, energy-saving and healthy. The ordinary metal halide track lamp takes the metal halide lamp as the light source. The luminous principle of the metal halide lamp is that the heavy metal element mercury reacts with the two electrodes after gasification to produce light, with large heat and radiation. It must be handled carefully after it breaks down, otherwise it may pollute the environment (mercury is a heavy metal element, which is harmful to human health). A typical feature of LED track lamp is energy saving. For LED track lamp and ordinary metal halide track lamp with the same brightness, the power consumption of LED track lamp is only 40% - 60% of that of ordinary metal halide track lamp, which shows its power saving effect.
