Example of Garage ceiling light

A customer sent us his installation example:
(LED retrofit kit and film diffuser can be purchased at easyledlighting.com)

What I wanted is to light up our garage as my workspace. The garage has bare wood studs roof but doesn't have light bulb base installed. What I want is something easy to install, bright enough low maintenance and not cost a lot.  

1) mount LED driver and LED modules between roof studs.

   Use screws to mount LED driver to wood stud, and using longer nail to mount LED module loosely and away from roof panel, so that the back of module won't be covered and air is still good to ventilate all around the module bracket, which double as heat sink.
At first, I use the diffuser film that designed for the module. The LED module and diffuser together is very light in weight (about 2 Oz), so I can  hang the module on the end of two long nails and it stays there.

2) Tidy up the wires, connect the power and the modules will just light up.
From the power plug, AC wire to LED driver is running on home AC, make sure you follow building electrical code for that 1 pair of wires.  After LED driver, the wires to connect each LED module are all running on low voltage DC. (The kit I purchased is 24V DC), therefore we can go easy on the wiring. After the wiring done and plug into wall socket, all LED modules light up instantly. But once the round shape diffuser is used, the light goes out at all direction and I realized I shouldn't install LED module between wood studs.

3) I purchased acrylic diffuser panel from HomeDepot (at lighting section, near florescent lamps), I cut into suitable size to cover space between wood studs, use drill to pre-drill screw holes. (can't nail or screw on acrylic panel directly)

4) Remove the diffuser film, mount the diffuser panel on wood studs to cover LED module. I have the diffuser panel cut to 16" long so there are at least 3" more diffuser coverage over both sides of  LED module. Screw them to wood studs.

5) Light up, the light is very bright and it looks neat from below.  Winter is coming and this LED set can withhold -20F, which I don't think it would get this cold indoor.

A peek review with our next generation World Lamp

We are making our next generation World Lamp shell. What shows in this photo is a prototype of 2.5mm coroplast, the real deal will be made with 4mm coroplast, which is much stronger than existing lamp shell.
We moved its opening to top of lamp, and use tab insert instead of snap lock to latch the cover pan.
Everything else remain the same, you still get a nice 30 watt LED core to shine through exactly the same dual lamp windows. The only thing that's going to change is color. Which color should we pick?

New Packaging of World Lamp

Our World Lamps have been our best selling item, but it had been always packed in 4 lamps package. The long box packs 4 lamp shells, and 4 smaller boxes hold one light unit each. Then the whole package is shrink wrapped in thick plastic cover to be water repelled. This is nice but anyone buys World lamp have to get 4; no change. Package come in just 8 lbs.

 Recently we found USPS provides this 37" triangle shipping tube for free if you ship priority. So we decided that would help our business to provide some flexibility. We split the box of 4 lamps into two priority shipping tubes, and our customer now can order 2 lamps at almost half of price of 4 lamp pack.
The 2 lamp pack come in under 4 lbs.

Mount Easy LED module to wood frame

The main enemy for high power LED is heat. Our special design quickly dissipates heat from tiny LED chip to large area metal mounting plate; but the end game is still to spread heat out of this module to its surrounding, air in most cases.

If the application is to attach LED module to metal lamp case, then heat dissipation won't be a problem at all. So is to set it by itself that both sides of plate exposed to free air.

However, it's common desire that we want to attach this module to wood frame, which is easy mounting. The bad thing about it is that: Wood dissipates heat slowly, by attaching one side of LED module plate to wood, it's like cover 50% of heat sink area to stop heat transfer to air. That's bad and what can we do if we have to?

     Keep Air Flow
Below is an example how I attach our module to wood frame. I use screw nuts as spacer to keep air still get in touch with both sides of metal plate. Also it would be wise to mount the module to an airy location to keep cool. The result is good enough to sustain heat dissipation.

What do you think of this LED Wall box light?

Our latest design: Easy LED Box light.

This is a Wall mount low cost utility light box like picture shown at below.

 

Tradditional Wall mount box light use fluorescent tubes in utility light box.

This one is about 4' long and use 70 Watt of Power.

 

Our Prototype LED box light is 28" long, prototype made with one piece of corrugated paper and diffuser film. The light is consist of two Easy LED module with mounting hardware. Liht output is 32Watt, mostly point toward at below where needed. The structure is extremely simple

 

There are two piece of Easy LED modules mounted on a bracket, with driver at middle.

module is bent to point light output at 45 degree below; and made small wedges at top for easy insertion of lamp cover box

The box is extremely simple as well, diffuser film at front opening and another opening

at back for hang at top of module assembly

 

All you need to do is to install the light module assembly to Wall electricity box, connect the wires.

Then put light box cover on to the light module assembly, it just hang by gravity and its edge will

 

snag fit in between wall and the module plates. Then the light is ready for use

LED panel Light

LED panel light is a flat panel that generates soft uniform LED light output. It usually come in with area size compatible to fluorescent Troffer ceiling light.  Unlike troffer lamp, LED panel lamp usually thick within 2" vs 5" thick of troffer lamp.
There are two ways to build LED panel light.
One way is to use multiple smaller LED to setup a matrix to make evenly light area light source. With no or little diffuser panel, an area panel can emit light evenly. This method requires circuit running at entire panel area, so it suits smaller panel better.

The other method is to set powerful LED light source at edge of panel, then place special light diffuser plate at entire area. This diffuser panel has special cuts and groves to make light through it distributed evenly. This way, the costly LED circuit won't be very large, more suitable for larger panel. However, this kind of diffuser plate won't be very thin and weights a little bit, and a reflective film at back to make sure light only come out at front. Since some light output is reflective light, so its usable lux per wattage is lower than other directional LED light applications.
