glass tubes

An LED lamp is a lamp which uses LED as its light source. LED stands for Light Emitting Diode. The light produced by a single diode is very small. Hence a collection of diodes are used together to get the adequate light. The wavelength of the light emitted by LEDs corporate premium is small. Hence the light emitted from the LEDs is strongly colored. The lighting for normal purposes requires white light. To convert the colored light that is emitted in to white light, the light from red, green and blue bulbs are mixed.


The other method is to use a phosphor to premium gifts convert the light in to some other colors. LEDs are used for both ordinary lighting in which white light is used and for special lighting in which colored light is used. If colored light is needed then an LED is used without any filters.online ups manufacturerdab4d58ck When white light is needed some of the colors are removed. Hence colored bulbs are more energy efficient because they do not Waste energy by filtering out the unwanted contents.


It is claimed that they are better than ordinary fluorescent bulbs. LEDs contain no mercury, unlike a CFL or Compact Fluorescent Lamp. LEDs can be turned on very quickly. Even if they are repeatedly turned on and off repeatedly the life time of an LED remains unaffected.


LEDs are also more durable and are less likely to break. White light LEDs have a long life time and consume only very less energy. These bulbs are also very small in size. The small size gives a lot of flexibility when LEDs are used in lighting systems. The distribution of the light can be controlled effectively to suit different purposes. LED lamps contain no glass tubes and hence have less chances of breakage. The same reason makes these bulbs more durable also.


LEDs are also used in flash, bicycle lights and in certain types of solar powered lights. LED lamps also find applications in gardening and in agriculture. LED lamps were used by NASA to grow plants in space. Ever since that LEDs have become very popular in indoor horticulture and gardening.PAR 38 LED In the LED lamps used for this purpose the wavelength of the light emitted facilitates chlorophyll absorption in plants. This promotes plant growth and reduces business gift wastage of energy. Energy is conserved as LED lamps do not emit the light of those wave lengths which the plants do not require.
