LED lamp cup, LED bulb and halogen lamp, traditional energy-saving lamp evaluation comparison

Most people like to decorate their homes in a warm and gorgeous way. They usually use lighting to create the overall atmosphere in the home. Therefore, a large number of tungsten bulbs or candle bulbs are used in the decoration, but every time you receive electricity at the end of the month, you must be attentive. It will also hurt for a while. Fortunately, the technology is always able to create a better life. In recent years, the most powerful lighting products are LED bulbs. It has many advantages such as environmental protection, energy saving and money saving. Therefore, every new LED product is always available before the launch. Everyone is eye-catching. Estimated how to sell LED light bulbs (3W/5W) and LED bulbs in mid-July this year? What are the breakthroughs in quality? Let's take a look at the details of these two light cups (bulbs) with the testers.

LED light cup: Named from the whole body of the lamp body like a funnel shape, the light cup uses ultra-high brightness light source, suitable for indoor mood decoration of hotels, bars, western restaurants, cafes, home interiors, boutique display windows, etc. Partial close-up lighting of crafts, jewellery, antiques, art photo patterns, product displays, etc., can directly replace the original ordinary spotlights, and its brightness is higher.

LED bulbs: Since the development of technology, LED is currently the most energy-efficient lighting products, but because incandescent lamps and electronic energy-saving lamps still occupy a very high proportion in people's daily use, in order to reduce waste, LED lighting manufacturers must develop LED lighting products that conform to existing interfaces and people's habits allow people to use a new generation of LED lighting products without having to replace the original traditional lamp base and wiring. Then LED bulbs came into being.

First, the shape of creativity

In this era of our lives, the homogenization of similar products is a very common phenomenon. First, because consumers prefer the appearance of the elements, and second, if you want to jump out of the traditional sample, product appearance research and development is also A small fee. However, the first time I met, the new LED products still gave the testers a lot of surprises. Let me talk about the LED MR16 lamp cup. Many of the products in the past do not seem to have the unique cold feeling of metal, the cheap feeling and the dullness of plastic.

Let's take a look at another: LED bulbs. The size of the bulb is A60, the power is 5w and 8w, but from the appearance, 5w and 8w are no different. Objectively speaking, this bulb is not much different from the products being sold on the market. It is a classic, well-behaved and versatile route. However, careful consumers may find that, unlike the straight lines in the past, the radiator part of this LED bulb has curved lines. This small design is for the sake of good looks and also to increase the heat dissipation area.

Second, technical characteristics (material selection, interface, light source, chip, process technology)

1, professional cooling

Just now we mentioned heat dissipation, using the heat-dissipating method of cold-extruded aluminum integral heat-dissipating adhesive. Pure aluminum material, 1200T punching machine, die-casting, high lamp body density, better thermal conductivity, streamlined design, beautiful appearance, better heat dissipation effect. .

2, universal interface security and environmental protection

The shape is designed to be more beautiful, and also to enter the homes of ordinary people. LED bulbs are common large threaded ports, which can be matched with the base and circuit of traditional tungsten or energy-saving lamps in the home, and are not wasted at all; and the solder-free lamp head is used at the interface, which is safe and environmentally friendly. .

3, single light source leading edge chip

The LED MR16 (5W) lamp cup adopts a single light source design, which is more convenient for light distribution, and avoids the diffraction phenomenon after mixing, without chromatic aberration and ghosting. In addition, the product uses COB integrated package chip, chip Directly mounted on a high thermal conductivity substrate, the heat dissipation channel is short, so that the heat dissipation efficiency of the chip is higher, more stable and reliable.

Third, the specific performance of LED lamp cup (brightness, heat)

Introducing so many situations, it is time for lighting products to "light". Each product has a different wattage. To distinguish it, we use 3W LED lamp cups and 5W LED bulbs for actual testing.

Add another sentence: MR16 is a standard specification jointly developed by many manufacturers. Since the LED lamp has accelerated the replacement of incandescent lamps in 2010, LED MR16 is one of the development focuses of LED lighting, while modularity and replaceability are It is the development trend of LED MR16 products. Back to the topic, there are generally such convenient lamp holders in the store, which is very convenient to use.

This LED lamp cup is warm white temperature, using PMMA lens, which has good transparency and stability. Next, use a halogen lamp to compare and test the heat performance of the LED lamp cup. Generally speaking, the lamp cups should be complete with a constant current driver and a casing. First, a set of them is a family portrait.

Commonly available in the market is an integrated LED ceiling light. The difference between it and the LED light cup is that the integrated LED ceiling light is mainly to meet the needs of new customers; the LED light cup is mainly to meet the needs of customers who replace or match traditional ceiling lamps. We assembled these items one by one in sequence, as shown below, with LED lights on the left and halogen lamps on the right.

After comparison, the halogen bulb has higher brightness and the LED light performance is softer; however, the halogen lamp has its fatal disadvantage: the power consumption is large, and the lamp body generates a large amount of heat. The same is the lighting time of 30 seconds, the temperature of the LED light does not change, the finger can directly touch the lamp surface, but the halogen lamp next to it is too hot to get close.

Third, the specific performance of LED bulbs (brightness, heat)

When testing the brightness of LED bulbs, we added 5W energy-saving lamps for comparison.

The power is the same as 5W, and the brightness of LED bulbs is better than that of energy-saving lamps. According to the national energy efficiency standard, the luminous efficacy of 5W energy-saving lamps that meet the energy efficiency requirements of level 1 is greater than or equal to 54lm/w, and according to laboratory test data, LED The luminous efficiency of the bulb product is 70lm/w, which is 30% higher than that of the energy-saving lamp of the first-class energy-saving lamp, and the service life is about 2.5-3.5 times that of the energy-saving lamp product.

In addition, this LED bulb mask adopts the industry-leading Mitsubishi high-quality PC material, and the light transmittance is higher than that of ordinary products. At the same time, the gas-assisted injection molding technology combined with the special structural design can make the whole lamp emit an angle of 210°, which is larger than the ordinary brand bulb.

LEDs are made of non-toxic materials, unlike mercury-containing fluorescent lamps that can cause pollution and can be recycled. There is no ultraviolet light or infrared light in the LED spectrum, neither heat nor radiation, and it does not attract mosquitoes; the advantage of the cold light source is that it can be safely touched, which is a typical green illumination source.
