Let LED send out incandescent light

Long night, when a person, you have missed the bright yellow incandescent light? In Japan, the incandescent lamp energy efficiency is too low, has been banned from production, but there are still a lot of people still miss the warm glow of incandescent lamps. How can we keep this precious light source and improve the energy efficiency? Panasonic decided to combine incandescent and LED, so CLEAR LED was born.

In fact, the current LED lamp also has its weakness, is the diffusion of light. It would be great if you could put the advantages of the incandescent lamp into the LED light. Well, that's what Panasonic thinks

Panasonic engineers said that the combination of incandescent and LED is the most perfect lighting. With a warm atmosphere of nostalgia, but also can reduce energy consumption. Panasonic CLEAR LED development team leader, said he as an old technician, for a long time the use of incandescent suddenly disappeared, said it was not suited, so they can produce CLEAR LED.

So, how is it possible to make LED glow like an incandescent lamp? The secret lies in the filament. The initial development of the project is the "like" and "light diffusion". Because LED is a linear light source, so it is difficult to diffuse light.

The usual LED light bulbs are semi transparent, in order to allow the expansion of the light and the reflection plate. But it's not working because of the incandescent light. In order to solve this problem, code named LDA4LC filament into the developer's line of sight.

CLEAR LED uses the most transparent alumina substrate, so that the heat transfer of the light is more excellent.

Then there's a problem. The general LED lights are built with a fixed water green light panel, which is attached to a yellow phosphor. So what about CLEAR LED? The answer is that the phosphor is loaded into a sandwich with two transparent substrates, and the surface is extremely smooth, so as to restore the soft and warm light of the incandescent lamp.

In order to reduce the effect of incandescent lamp, the position of the light source is the same as the old incandescent lamp. The two thin pillars and the conductive wires, etc., are all the same. The goal is to change the light into LED, the other is exactly the same.

As a light bulb, there is a need to solve the energy efficiency. The usual LED bulb is covered by a large heat sink, so that the heat is not lost while increasing the life of the LED.

However, the Panasonic CLEAR LED filament is floating in the air, so the original relatively large heat sink can not be used. The production team did not do two endlessly, simply using a new type of white resin sandwiched between the filaments and pillars of the gap.

The resin is suitable for heat dissipation, and has high plasticity. LED heat transfer through the heat conductivity of aluminum alloy, to the resin for heat dissipation. The final effect is the figure above.

In order to achieve the ultimate and incandescent exactly the same, Panasonic developers can not spend less effort on the LED dimming, as far as possible to achieve the brightest and most similar. The development goal of the production team is the color temperature and 40W, 60W incandescent lamp completely consistent. In order to achieve the effect of the incandescent light of the classic retro, R & D personnel can be described as moving enough brains.

The actual use in the electric light, ordinary energy-saving lamps and LED lamps can not match the visual effect of the display. Restore the crystal lamp shining like a dream lighting effect, a simple light bulb, completely changed the indoor atmosphere.

Like the stars, so beautiful lighting effect is absolutely ordinary LED bulbs can not match.

Panasonic CLEAR LED won the 2011 GOOD Gold Award in Japan, the German iF product design award in in 2012. It has started selling in Japan and Europe, but has not yet entered china. Small series is very much looking forward to CLEAR LED into the homes of ordinary people.

It is said that the color of human cognitive sources in the ancient times of the sun, in the savage valley land, yellow sun can bring people warmth and hope. Panasonic engineers in the development of CLEAR LED, the time must have a similar mood, right?
