Who is brighter with the same power LED or COB street light?

It should be LED lamp, LED lamp has the advantages of low energy consumption, high brightness, small size, low heat, long service life, etc., the energy consumption under the same brightness is only 20% of the incandescent lamp, 30% to 50% of the energy-saving lamp, it is the lighting product with the lowest energy consumption in the civil market, very cost-effective, good economy.

The brightness should not be very different, because the light effect of LEDs is basically the same. The difference lies in the chip distribution of the two light sources. COB is also a type of LED, and their luminous principle and chip are the same. So it should be about the same.

LED and COB street lights are both common lighting devices, and they have some differences in lighting effects. At the same power, COB street lights are usually brighter than LED street lights.

First of all, LED (Light Emitting Diode) is a semiconductor light source that produces light when an electric current is passed through a semiconductor material. LED street lights are made up of multiple LED chips, and the power of each chip is usually between 1-5 watts. Although the LED chip is small, due to its efficient photoelectric conversion efficiency, LED street lights can provide high brightness at the same power.

In addition, LED street lights also have the advantages of long life, low energy consumption and environmental protection.

COB (Chip on Board) street light is a lighting device that integrates multiple LED chips on a module. COB chips are usually densely packed with multiple LED chips, which can provide higher brightness by integrating them together. The power of COB street lights is usually between 10-100 watts, in contrast, LED street lights have less power.

Therefore, at the same power, COB street lights are usually brighter than LED street lights.

However, it's important to note that brightness isn't the only measure of lighting performance. In addition to brightness, there are other factors to consider, such as color temperature, color reproduction index, beam angle, etc. LED and COB street lights also have some differences in these aspects.

For example, COB street lights typically have a higher color temperature and a better color reproduction index, which can provide a lighting effect that is closer to natural light. LED street lights can achieve different beam angles by adjusting the number and layout of LED chips to meet different lighting needs.

To sum up, although COB street lights are usually brighter than LED street lights at the same power, other factors such as color temperature, color reproduction index and beam angle need to be considered when choosing lighting equipment to meet actual needs.

LED street lamp is semiconductor lighting, it is a solid-state cold light source, with environmental protection and pollution-free, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lamp is the best choice for road lighting energy-saving transformation.

LED street lights are generally transformed from ordinary street lights, which are city circuit lights with a voltage of 220V. Solar street lamps are generally used for photovoltaic power generation with 12V and 24V low-voltage voltages, and the lamp heads used are LED street lamp heads for lighting. Now the installation of municipal roads is generally LED street lamps to save electricity for lighting and achieve the purpose of energy saving, and the cost of solar street lamps for municipal road reconstruction is higher, so it is generally only used for rural lighting, which is not easy to wiring in remote areas.

The advantages of LED street lights are environmental protection and pollution-free, low power consumption, energy saving and environmental protection, high light efficiency, long life, safety, fast response speed, and high color rendering index.

LED street lamps are different from conventional street lamps in that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, which can be widely used in roads, and the cover can be made with high temperature resistance of up to 135 degrees and low temperature resistance of -45 degrees.

Applicable places: urban roads, sidewalks, squares, schools, parks, courtyards, residential areas, factories and other places that need outdoor lighting.

LED street lamps are different from conventional high-pressure sodium lamp street lamps, and the light source of high-power LED street lamps adopts low-voltage DC power supply, high-efficiency white light diodes synthesized by GaN-based power blue LEDs and yellow phosphors, which have the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high color rendering index, etc., and can be widely used in urban road lighting. The outer cover can be made of PC tube, and the high temperature resistance is 135 degrees. Lightemittingdiode (LED) is a high-efficiency solid-state light source based on semiconductor PN junction formed with weak electrical energy, under a certain forward bias voltage and injection current, the holes injected in the p-region and the electrons injected into the n-region are diffused to the active region and emit photons through radiation recombination, which directly converts electrical energy into light energy.

1.Generally, the luminous efficiency of the COB of the Taiwan chip: 65 80lm W, the higher the power, the lower the luminous efficiency.

2.Generally, the luminous efficiency of single-chip LED (commonly known as single lamp) of Taiwanese chips: 80 110lm W, the larger the chip size (area) under the same power, the higher the luminous efficiency.

Spotlights are now composed of single lamps and COB products, and according to the above principle of light efficiency, it is possible to distinguish which one is bright at the same power.

Compared with the lights of COB and LED, COB is a little better because it is more cost-effective.

The light source of the cob spotlight allows people to get very good protection for their eyes, especially the eyes of friends who are nearsighted. The daily electricity bill is small, saving energy and saving the cost of production and use. The installation of COB spotlights is simple and takes little time.

The light source of COB spotlight is the best COB light source at present, and it is also the mainstream trend of the development of China's lamp era at present and in the future.

Although COB** is a little more expensive than LED, the cost of COB light source itself is higher, and the overall heat dissipation performance is better than that of general LED light source, and the cost performance is relatively high. The COB light source is also a type of LED light source, but it is an integrated packaged LED light source.

The difference between COB and LED lights

1. COB luminous flux density is high, the light color is close to the natural color, no flicker, there is no divergent glare, and the light source is softer than the slag. No ultraviolet radiation, no electromagnetic radiation, no infrared radiation, can protect the eyes and **.

COB lamp is a spotlight that uses a COBLED light source as the light source. COB light source is LED chip directly attached to the high reflectivity of the mirror metal substrate of high luminous efficiency integrated surface light source technology, this technology eliminates the concept of bracket, no electroplating, no reflow soldering, no patch process, so the process is reduced by nearly one-third, the cost is also saved by one-third, generally speaking, it is better than LED lights, more eye-protective lights.

The difference between LED lights and COB lights is that LED lights are energy-saving, environmentally friendly, no strobe and no ultraviolet radiation, and the disadvantage is that blue light is harmful. The COB lamp has high color rendering, the light color is close to the natural color, no strobe, no glare, no electromagnetic radiation, no ultraviolet radiation, infrared radiation, which can protect the eyes and **.

The light source of COB spotlight refers to the chip directly binding and packaging on the entire substrate, and the chip is integrated together on the substrate for packaging, which is mainly used to solve the problem of low-power chips manufacturing high-power LED spotlights, disperse the chip heat dissipation, improve the light efficiency, and improve the glare effect of the LED lamp. The COB emission has a high luminous flux density, less glare, and soft light, which can emit a uniformly distributed light surface.

The meaning is different, the chip used is different, and the bracket is used.

The meaning is different: COB refers to the chip directly bonded packaging on the entire substrate, that is, N chips are inherited and integrated together on the substrate for packaging; LED lamps are light-emitting diodes, which are light-emitting materials using solid semiconductor chips, and compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, have good color rendering and response speed.

The LED chips used are different: the COB light source is mainly a low-power LED chip of less than 1 watt, and a very small number of COB light sources will also use a high-power LED chip of more than 1 watt; LED integrated light source generally uses large-size and high-power LED chips of more than 1 watt, and the chip size is generally more than 30mil.

The brackets used are different: there are many sizes of brackets used by COB light sources, and their shapes are square, rectangular, oval and other dozens of brackets of different sizes, and their materials are mainly aluminum, and there are also brackets made of copper and ceramic, generally without side feet; The bracket used by the LED integrated light source is only 10W, 100W, 500W and other square brackets, which are mainly made of copper, and the brackets are equipped with 2 side feet.

COB refers to a type of encapsulation of lamp beads.

Cob lights are also a type of LED lights.

COB is different from a single LED, mainly depending on the power, and there is not much difference between the two with the same power.

Also look at reflectors, lenses, etc.

LED is a light-emitting diode, is a semiconductor solid-state light-emitting device, he uses solid-state semiconductor chips as light-emitting raw materials, when the two ends add forward voltage, the interceptor compound of the semiconductor causes photons to heat up and produce light.
