With the progress of the LED energy-saving lighting technology, all kinds of lighting light source are using LED as the light source, to shoot the light is not exceptional also, LED lamp is similar to the tube light, is a commonly used in the embedded in the ceiling installation of decorative lighting lamps and lanterns, usually the light soft and have ability to focus. What are the characteristics of led spotlights? Below small make up brief introduction led shoots the characteristic of the lamp to have what.
Introduction to led spotlights
Led spotlights are divided into low-voltage and high-voltage types. Consumers are advised to choose low-voltage spotlights with longer service life and higher light efficiency. Shoot the light efficiency of high and low to power factor, power factor, the greater the photosynthetic efficiency, the better, the power factor of ordinary lamp at around 0.5, the price cheap, high quality led lamp power factor can achieve 0.99, the price is a bit expensive.
The strengthening of led lamp is generally used in the decoration lighting, general is embedded in the ceiling or wall, shoot the lamp to work generally have a higher temperature, so be sure to buy the high quality product, otherwise there will be a security risk.
When using led lamp, it should be used with transformer. Lamp beads should also be of good quality. Otherwise, the lamp beads of the lamp will be easily broken.
Features of led spotlights
1. Energy saving: LED lamps with the same power consume only 10% of the electricity of incandescent lamps, which is more energy saving than fluorescent lamps.
2. Long service life: LED lamp bulb can work for 50,000 hours, longer than fluorescent lamp and incandescent lamp.
3. Adjustable light: the previous dimmer was always aimed at the incandescent lamp. When the incandescent lamp dimmed, the light became red. It is hard to see the dimmer of fluorescent lamp, which is the main reason why the dimmer technology has not developed for many years. Leds can be dimmed again, and both on and off are the same color (the color temperature is basically the same), which is significantly better than incandescent bulbs.
4. Frequent switch: the life of LED is calculated according to the time when it is on. Even if it is switched on thousands of times per second, the life of LED will not be affected.
5. Rich color: there are white, warm white, red, green, blue and other colors, no matter the small colored lights or neon lights used for decoration beside the main lights in the living room, they are very bright.
6. Low calorific power: like spotlights, many 220V spotlights break down in a few days because of heat. Although the calorific value of 12V halogen lamp is lower than 220V, its brightness is not up to the nominal value due to the insufficient power of the transformer. With LED spotlights, you can work for a long time without a transformer.
