Grotesque LED Light Bulb

3D-printable Breaking Bulbs by Gässling

With the developing of 3D technology, Innovative 3D-Printed designs rushed into market. Those fantastic breaking bulbs were made by Swedish designer Joakim Christoffersson (owner of Gässling). 

Breaking Bulbs capturing that split second in time when an object destroys on impact. The over-sized bulb-shaped lamps appear to shatter as they destroy when being dropped, smashed, and even shot.

The Breaking Bulbs are printed in white nylon material (very lightweight, durable and various color options). Designed with a cozy warm white in 6W LED power consumption and delivered with a power adapter.

3D-printable Tiny Cities Bulbs by David Graas

David Graas is a Netherlandish designer, studied product design at the Gerrit Rietveld Art Academy in Amsterdam and worked as an independent product designer since 2004.

Basing on investigation of relationship between functional objects and their users, David Graas made this LED light bulb. He wants to show people how these objects are valued and why. Not caring much for “pretty things”, his focus on ideas rather than style.

Trying to establish a long term understanding between his products and their users and prolong their lifespan in an era where the cycle of fashion spins ever faster.

Palm Hanging Light by Janne Kyttanen

Palm is inspired by the fluid and sweeping foliage found in nature. Janne Kyttanen created this eye-catching work of art which comes in a variety of sizes. Arranged in such a way as to allow light diffusion from both above and below each leaf, the light is an ideal solution for both downward and upward lighting with its simple and elegant design, such as use it as part of your decor, as a standing lamp, a table or ceiling light fixture.

Optical illusion flat light bulb

Studio Cheha out of Isreal is presenting us with these beautiful pieces of furniture depicting a 3D optical illusion from a 2D object-optical illusion compressed bulb (Bulbing).

Fairly with LED and optical equipment (wooden base acrylic glass) made a flat piece of optical network, only 5 mm thick - from the front your brain will register it as a 3D object, but turn it to the side and you’ll find that it’s nothing but a flat 2D object.

What is Waterproof Rating?

When talk about LED products we often mention waterproof rating (IPXX), but what water-proof rating is?

IP stands for Ingress Protection.

The rating’s first digit e.g. IP65 relates to the ingress protection against dust (6 means dust tight, see the table below)

The second digit e.g. IP65 relates to the ingress protection against water (5 means protected against water jets, see the table below)

Protection against solid objects
1st Digit	Description	Definition
0	Non-protected	No special protection
1	Protected against solid objects greater than 50 mm	A large surface of the body such as the hand (no protection against deliberate access). Solid objects exceeding 50mm diameter
2	Protected against solid objects greater than 12 mm	Fingers or other objects not exceeding 80 mm in length. Solid objects exceeding 12 mm diameter
3	Protected against solid objects greater than 2.5 mm	Tools, wires, etc of diameter or thickness greater than 2.5 mm. Solid objects exceeding 2.5 mm diameter.
4	Protected against solid objects greater than 1.0 mm	Wires or strips of thickness greater than 1.0 mm. Solid objects exceeding 1.0 mm
5	Dust protected	Ingress of dust is not totally prevented but dust does not enter in sufficient quantity to interfere with satisfactory operation of the equipment
6	Dust-tight	No ingress of dust
Protection against liquids
2nd Digit	Description	Definition
0	Non-protected	No special protection
1	Protected against dripping water	Dripping water (vertically falling drops)
2	Protected against dripping water when tilted up to 15º	Vertically dripping water shall have no harmful effect when the enclosure is tilted at any angle up to 15º from its normal position
3	Protected against spraying water	Water falling as spray at an angle up to 60º  from the vertical shall have no harmful effect
4	Protected against splashing water	Water splashed against the enclosure from any direction shall have no harmful effect
5	Protected against water jets	Water projected from a nozzle against the enclosure from any direction shall have no harmful effect
6	Protected against heavy seas	Water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities
7	Protected against the effects of immersion	Ingress of water in a harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time
8	Protected against submersion	The equipment is suitable for continuous submersion in water under conditions, which shall be specified by the manufacturer

Take strip light as example:

Non-waterproof LED strips: PCB (Printed Circuit Board) material with self-adhesive back

Waterproof LED strip-surface injection: Except it PCB material is encapsulated with plastic Gel at surface, with adhesive back, water resistant coat (IP-65)

Waterproof LED strip-silicon tube: Except it PCB material is encapsulated with silicon jacket. Without self-adhesive back, water resistant coat (IP-67)

Waterproof LED strip-whole injection: Except it PCB material is encapsulated with plastic GEL at both sides, Water resistant coat (IP-68)

General Parameters for LED

Lumen

Lumen is one of the most important parameters to measure the brightness of a light, the higher the number the brighter the light.

A lumen is a unit of standard measurement used to describe how much light is contained in a certain area. It is part of a group of standard measurements known as the photometry group, which measure different aspects of light. This group also includes such units as the candela, which measures luminance, and the lux, which measures illumination.

Power Consumption

In electrical engineering, power consumption often refers to the electrical energy over time supplied to operate an electrical appliance. Power consumption is usually measured in units of kilowatt hours (kWh). More accurately, power is the rate of consumption of energy, measured in watts or horsepower.

The energy used by equipment is always more than the energy really needed. This is because no equipment is 100% efficient. Power is wasted as heat, vibrations and/or electromagnetic radiation.

CRI

CRI (Color rendering index) is used to judge the accuracy of perceived color under artificial light. It is measured on a scale of 1-100, where the higher the number, the closer to standard colors (CRI=100) objects will appear. A compact fluorescent lamp bulb (CFL) with an 80 or above is suitable for residential use.

CCT

CCT (Correlated Color Temperature) also called color temperature.

CCT measures the appearance of the light itself, or how “warm” or “cool” it seems. Oddly, the lower the CCT value is, the warmer the light; CCT values below 3100 K indicate a warm white light. Standard incandescent bulbs have a CCT of 2800. Many fluorescents have a CCT of 3000 and provide the same warm, white, light that an incandescent bulb produces.

LED Bulb Shape and Common Fixture

     In this LED TIMES, LED products can be seen anytime in anywhere. LED (light emitting diode) is an electronic device that lights up when electricity passing it.

LED light means use LED as source of illumination while most light comes from an incandescent or fluorescent light bulb. Different from the traditional bulbs, LED has the advantages of high efficiency, energy saving, long life, environmental protection. They also can be put into traditional lamps as other incandescent or CFLs.

LED bulb shape and common fixture

Different bulb shape or base type suits for different use. There are some universal LED bulbs and every bulb is coded with a letter. Refer to the guide below for all standard bulb shapes and their corresponding letters
