One of the most commonly asked questions in this lighting age is the difference between LED lights and
solar lights. A lot of people often wonder whether a 100W solar lamp can achieve the same brightness level as a 100W LED light. And, apart from the brightness level, are there other differences between these two types of lighting? In order to differentiate the LED and solar lighting, there are a few things that you must note. First of all, it is essential to note that "solar" indicates a way in which energy may enter a system. In the case of solar lighting systems, it denotes that the systems get their electricity from solar cells. The source of energy for solar cells is the energy from the sun. On the other hand, LED denotes how energy leaves a system, usually in the form of light generated by diodes. LEDs are driven by electricity. LED lighting is the direct power supply of the grid. Electricity from various sources, including solar cells, can be used for various purposes, including driving LEDs. Therefore, solar lights and LED lights are neither antithetical nor equivalent. The most obvious correlation is that the impracticality of solar power implies that it must be eked out efficiently, and LED lights are the most efficient lighting systems at the moment. "Understanding the difference between the two lighting systems is crucial for their appropriate application." - Bill G. - General Manager at LEDLightExpert.com This blog will examine how the difference between the two lighting systems influences their applications. A
light-emitting diode (LED) is a light source comprising two semiconductors. Otherwise known as a pn-junction diode that emits light upon activation. LED is a semiconductor that gives light when electric current flows through it. The current passing through an LED causes the electrons to recombine with holes emitting light. LEDs only allow the current to flow in the forward direction. This system blocks the current from flowing in the reverse direction. The two semiconductors are made of astringent materials categorized as p-type or n-type. The n-type and p-type materials are dipped into a substance called "a doping agent." The doping process slightly alters the electrical properties of these materials from their unaltered, pure, or "intrinsic" form, i.e., the i-type.
What are the components of LED Lighting?
When the diode only allows the forward flow of current, the minority electrons are sent from p to n. At the same time, the minority holes are sent from n to p. The whole process increases the concentration of minority carriers at the junction boundary. Then, the excess minority carriers at this particular junction recombine with the majority charge carriers. Upon this recombination, the energy is released as photons in a phenomenon known as electroluminescence. And this is the case with the light-emitting diodes. In the standard diodes, this energy is released in the form of heat. Electroluminescence is an electrical and optical phenomenon where a material emits light in response to the passage of an electrical current. The emitted light is usually directly proportional to the forward voltage until it reaches a maximum.
What are the advantages of LED lights?
The increasing popularity of LED lights is highly attributed to their advantages, which include the following:
- They consume less energy and require low operational voltage.
- They are environmentally friendly.
- No warm-up time is required.
- They exhibit long life and ruggedness.
- High level of brightness and good light quality.
Solar lighting can be described as
outdoor lighting powered by the sun. The energy is collected or absorbed by the solar panel during the day. The absorbed energy is then used to charge a battery that will power the fixture in the absence of the sun. "If you are looking to illuminate a garden, pathway, street, etc. LED Solar lights can be the right choice for you" - Bill G. added.
What are the the essential components of solar lights?
- A solar panel (EV).
- A high-efficiency fixture.
- A rechargeable battery. Note that there are several types of batteries.
- Controller.
Solar lights make use of photovoltaic (PV) cells. These cells absorb energy from the sun, creating an electrical charge that passes through the panel to the battery. Wires are used to connect the solar cells to the battery. It is in the battery where the electrical power is converted and stored as chemical energy until required. The stored energy will later be used to power a lighting fixture. Due to the amazing combination of LED lighting and solar lighting, using solar energy to power an LED bulb is highly recommended. The energy efficiency of LEDs explains why they are ideal for solar lighting systems, like
solar parking lot lights.
What are the advantages of Solar LED lights?
The ever-increasing popularity of solar lighting systems is attributed to the following advantages:
- Solar lights rely on readily available solar energy to power lighting systems.
- They are environmentally friendly.
- Their off-grid operation promotes off-grid living.
- Ease of installation
- Cost-effectiveness
