Why Lumen Of Per Watt Is Differen From Lights?

Most people know that long lifespan LED lights are more efficient and energy-saving than incandescent lights and fluorescent lights, but most of us do not know what the inside core value provides such various functions from them. In the following, we would like to dig out the secret of why the lumen output is different per watt from three kinds of lights.

Let’s look at the lumen index of per watt between LED light, fluorescent light, and incandescent light.

From the above sheet, we can acknowledge that the relationship of incandescent light, fluorescent light, energy saving light, and LED light is stepwise which has more and more brightness in the same watt. What caused such a situation may relate to its luminous medium. Let’s see their light light-emitting principle.

Incandescent light

Nowadays, the energy-saving products we are talking about are mainly for incandescent lamps. Ordinary incandescent light is about 10 lumens per watt and has a lifespan of about 1,000 hours. Its working principle is: when the lamp is connected to the circuit, the current flows through the filament, and the thermal effect of the current causes the incandescent lamp to emit continuous visible light and infrared light. This phenomenon can be detected when the filament temperature rises to 700K. Very high, most of the energy is wasted in the form of infrared radiation, due to the high temperature of the filament, the evaporation is also fast, so the life is also greatly shortened, about 1000 hours.

Fluorescent lamp

Energy-saving lamps are also called compact fluorescent lamps. Because of their high light efficiency, obvious energy-saving effect, long life, small size and convenient use, they are valued and welcomed by people and countries all over the world. The working principle of fluorescent lamps: the Gong steam in the lamp tube is discharged under the action of an electrified electric field, and the valence electrons of the mercury atoms are continuously excited from the original state to the excited state, and at the same time, the excited state returns to the ground state spontaneously, converting the potential energy of the valence electrons. It is converted into electromagnetic radiation energy, radiates ultraviolet rays, and the fluorescent powder coated on the inner wall of the glass tube absorbs the ultraviolet rays and converts it into visible light. Different phosphors have different luminous colors, this phenomenon is called photoluminescence. Fluorescent lamps work on the basis of gas discharge and photoluminescence.

LED: LED, also known as a light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply so that the entire chip is encapsulated by epoxy resin. LED wafers are made up of various elements such as arsenic (AS), aluminum (AL), gallium (Ga), indium (IN), phosphorus (P), nitrogen (N) and strontium (Si). The luminous brightness is also divided into several levels of properties.

What Else Can Affect The Brightness?

In addition to the luminous medium influent the the brightness under the same wattage condition, the quality of components of the lights will also affect the brightness. So different components in various LED lamps lead to varying brightness with the same power consumption.

How To Pick Efficiency One In The Same Power Consumption?

Without no doubt the LED lights are the first choice of high-performance lighting fixtures. If you want to compare one type of LED light under the same power consumption, here will take UPSHINE Triproof LED batten for your reference when you looking for batten lights and comparing them in a different store.
