E14 reflection lights can be a nice replacement for LE

I have recently reported already thought about LED replacement for my Halogen spotlights and am very happy with the result. Now a E14 reflection light in the kitchen I broke down and I've been looking here for a replacement by an LED reflection light source.

Unfortunately, the choice of lamps with this base and in this form is still quite clear. Both in our local hardware stores, and on the Internet, there are mainly pretty ugly representative, which are a GU10 lamp with an adapter in the base. Since my radiator in the kitchen quite open hanging from the ceiling, this eye insults came out of the question for me.

Luckily I then came across the Lighting EVER R50 Reflection Light Sensor with E14 base. Although my previous experience with Lighting Ever was rather mixed, I've ordered me four of these lamps.

The lamp emits much heat. A radiation to the rear - normally as usual with the reflection lights - is prevented by the wording. For me, not a problem as I use the lamps as a work surface lighting, in other applications, which can, however, provide for an unsightly light distribution...

All in all, the Lighting offers a nice alternative to incandescent bulbs. The light is warm, without drifting into the Yellow, the brightness is high (perhaps also by the lack of radiation to the back and to the side) and the price is also reasonable.

Today I got even a "normal" E14 LED Candle in shape with 3W of Lighting Ever. Again, the report is true basically. The lamp is very bright and warm. The lower part of the lamp is made of ceramic, which prevents radiation for the collection and a slightly different illumination characteristics as normal candle bulbs has. With 8, - EUR the lamp is as favorable as the reflection light version.

Smart dimmer controller: use your gesture to control lighting

For most of us, want to turn the house lights, fans and air conditioners and other appliances need to use a different switch / remote control. However, with the development of home automation, we will soon be able to use a gesture to control more than one device, which is also Ube's WiFi Smart dimmer controller want to achieve. Ube Production Company released an updated version of the smart dimmer controller at this SXSW show, able to house other smart devices control.

As the name implies, smart dimmers through the sliding surface of the touch pad to adjust home lighting. Simply slide open / close the lights, use two fingers to adjust multiple lights. Now, Ube longer satisfied merely to adjust the lighting, the upgraded version of the intelligent dimmer controller can control other intelligent devices, such as using a finger to write "W" will open sprinklers, or write "A" to turn on / off the home alarm devices.

Changing the light flux of the light source means to adjust the level of illumination of an electrical device. And the composition of the system capacity is called modulating means. Its basic principle is to change the input source to achieve the purpose of RMS current dimming. Dimmer different purpose is to adjust the light brightness. RMS voltage by reducing or increasing the average power of the light produced to promote the different intensity of light output. Although the variable voltage device can be used for various purposes, but the regulation is intended to control the illumination.

The size of a normal lamp switches for small units of large theater or architectural lighting home lighting, high power units used. Small units dimmer controllers are usually direct control, high power units are using a remote control system.

How to deal with LED downlight bulb heat problems

With the summer season decoration, lighting industry is no exception, currently the most fashionable LED downlight bulbs, but also by the majority of consumers in hot pursuit, but few people know how LED downlight bulbs are conducted heat, below we hear Vauban LED downlight bulb LED Mall for a detailed description of the heat.

This is the most common way of cooling, aluminum fins as part of the housing to increase the cooling area. The use of liquid bulb packaging technology has high thermal conductivity of the transparent liquid filled LED downlight bulb in the lamp body. This is in addition to reflective principle, the only use of LED chip smooth thermal conductivity, thermal technology.

In the home-based lower power LED lamps, lamp often use an internal space, the driver circuit portion or all of the heat into. Such as screw cap can be used with such a large cooling metal surface of the lamp, because the lamp is a metal electrode and the socket -contact power supply line. So part of the heat can be derived there from heat.

Thermally conductive filler material in the injection molding of plastic shell, plastic shell increases thermal conductivity, heat capacity. Lamp shell reinforced with longevity and efficient internal cooling fan, low cost, good effect. But the trouble is that some fans want to change, does not apply to outdoor, this design is more rare.

Use of heat pipe technology allows the heat to be generated by the LED chip lead into the housing fins. In large lighting, such as street lamps is a common design. The purpose is to reduce the heat of the lamp envelope of the operating temperature of the LED chip, the LED chip we used the thermal expansion coefficient and thermal conductivity of metal, thermal expansion coefficient, a large gap between the material can not be welded directly to the LED chip, so high, low thermal stress damage of the LED chip. New ceramic material with high thermal conductivity, thermal conductivity close to aluminum, and the expansion factor can be adjusted to synchronize with the LED chip. This can be thermal, heat integration, reduce heat conduction intermediate links.

Do light shell surface radiation heat treatment, a simple paint is applied radiant heat, radiant heat can be removed from the way light shell surface. Use light shell shape, creating a convection air, which is the lowest -cost way to enhance heat dissipation.

Steps to follow when choosing multi light fixture for your home

Selection dome light, we must first consider changing light bulbs inconvenient, after the entire bad bulb is a very common thing, if the room is high enough, the chandelier is a good choice. But to figure out the caliber cap screw, because some non-standard caliber can not use energy-saving light bulbs.

In addition, a large kitchen and bathroom water vapor, more humid, and therefore should also be considered when buying waterproof multi light fixture problem.

Palace-style carved hollow chandelier delicate lines, carving delicate. But too complex even for complex modeling small size of the room will be overwhelming and depressing feeling, plus northern air is dry, dusty, too complicated multi light fixtures clean up will be very troublesome. Modern advocating simplicity, multi light fixture, too, is simple does not mean simple, simple shapes often more contemporary, coupled with strong texture of metal color, is the real finishing touch.

Lighting the entire room is designed to complement, therefore should be coordinated in style to each other well. A lot of people in the hallway or living room decorated like iron products used for decoration, such as glass door with wrought iron flower stem, is hanging on the wall clock wrought iron, wrought iron dining tables and chairs are also very beautiful, if accompanied by an iron pipe material chandelier the effect will be very good; while security has golden hands, golden yellow spotlights bedroom, gold decorative lights can also be mated. In short, the different functions of the same indoor multi light fixture style, color and style is best to unity.

Multi light fixture is the most direct function of light, but just enough to let the light against the background of our daily life, of which there are a lot of knowledge. Lamp, the different options, the resulting projection effects and mood there will be many changes. Sheepskin shade and Japanese paper shade, texture relatively, soft lighting and elegant; imitation mahogany combined with rosin jade shade, can light turns yellow, into a fun match with mahogany furniture, antique, can become a unique decor objects and furnishings to complement and foil; those Roman -style metal lamp itself is a miniature sculpture, quite artistic temperament.
