How much do you know LED wash wall lamp

LED wash wall light first used in building outline, overpasses, monument, pillar, flower beds and other places of decorative lighting. Wash the wall lamp application rigorous industrial design, compact appearance unique strong, has the characteristics of safe and reliable, easy to operate, has the good close mixed color without a shadow of the unique role, high lumen output. Unique structure is advantageous to the shell on the flow discharge, new-style waterproof silicone, can ensure the sealing of lamps and lanterns, ensure no water and dust.

as a new type of energy-saving light source, LED is widely used in lighting, energy saving, it use long life are the common consumers love, but how many consumers truly understand wash wall lamp? With below small make up together to get to know the LED wash wall lamp.

1, LED brightness ( ' Different, the price is different. Used for LED lamps and lanterns, the LED should comply with the laser level Ⅰ class standard.

2, leakage current, the LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, short service life, low price

3, wavelength leds together, color is common, such as requiring color, the price is high. Not the manufacturer of the LED light color separation instrument is not easy to produce color pure product.

4, luminous viewpoint use different LED the luminous point of view is different. Special luminous point of view, the price is higher. Such as the diffuse Angle, the price is higher.

LED wash wall light common lens has the following material:

( 1) Silicone lens: a small volume of silicone lens high heat resistance, can be a reflow soldering so it is often used in the LED packaging industry.

( 2) PMMA lens: PMMA lens is commonly used to wash the wall lamp lens we said today, also the industry call: & other; Acrylic optical lens & throughout; , its primary characteristic is pervious to light function can reach more than 90%, relative to the function of heat-resistant silicone lens is a bit weak, temperature less than 80 degrees Celsius.

( 3) PC lens: the same PC lens is the optical lens the pervious to light function is about 10% lower than that of PMMA lens slightly, but its heat and temperature is higher than that of PMMA lens by more than 45%.

( 4) Lens: glass lens is above the highest price in several kinds of lens, because the production equipment of this kind of lens price appropriate, although the pervious to light function can reach more than 97%, but we all know glass is a fragile substance, so little glass lens on the market as a lighting lamps and lanterns of optical lens.
