正常，天下文章一大抄，昨天我发那个曾志伟的开关结构正是EZAA用的结构了

The titanium "Sapphire"

Background:

This light is based on the Arc AAA flashlight.

In communication with Peter Gransee of Arc Flashlight, this light was brought up in discussion. I have been interested in a titanium AAA flashlight for a number of years and have made a few prototypes and custom samples. The most recent sample used an Arc AAA converter that Peter had given me. I asked Peter if I could get some converters from him for use in a run of titanium AAA lights. Peter offered to build some Light Engines for me using the Nichia 310DS LED (supplied by me). In consideration of Arc Flashlight providing me with these light engines, it was agreed that I would supply them with a portion of the run of titanium sets which I had designed and had fabricated. I would do "my thing" with my lot of components and Arc would do "their thing" with the components they have.

To be more specific on how this light is based on the Arc AAA, the geometry and threads are the same so that in theory the head and battery tube are interchangeable. The converter that drives the LED is the same converter used in the current Arc AAA. The choice of LED is different. The profile and exterior form of the head and battery tube are different. The head in this light was designed specifically for hosting the 3 mm LED and there is a sealed sapphire window in front of the LED. A cross section detail of the head and battery tube is below:

I took a Sapphire with red LED out on the reef to see how the red would work in the dark areas. It couldn't really compete with the harsh contrast and strong ambient light. I did spot an octopus though and used the light as a "probe". The octopus turns a dark brown when it wants to disappear in the shaddows and even the red didn't reflect well off its surface. Did show up the white of its eye though:

The octopus came out on the other side of this coral and I took the light down to see if I could get it to respond to the light itself. It grabbed the light and fortunately my finger slipped into the large split ring or I would have lost the light to this guy! As it was, it was quite a tug of war until it let go.

Nichia 1/2 watt High CRI LED bonded directly to sapphire window:

Driving the LED at 80 mA, I measured the temperature of the LED and window with a FLIR. Although in the image above, you can see a captured picture on the FLIR showing the window at 51.6 C, after leaving the LED powered up for a longer period until presumably steady state was reached, I then measured 54.5 C on the face of the window and 56.4 C on the back of the LED package. With the window removed, the temperature of the LED rose to 65 C. When installed in the head of the titanium AAA host, below, the head of the light does get warm to the touch indicating that further heat is spread to the light itself. Once the window and LED were installed in the head, I added further Norland 61 UV curing adhesive behind the LED essentially potting it in the head and adding thermal mass and transfer capability.

Some comparisons with the Sapphire hosting the Nichia 310DS LED:

The comparative images below showing the color checker were taken with the camera set on daylight white balance:

The tint seen on the "white wall" behind the ColorChecker is in keeping with what the naked eye sees but a bit exaggerated

I introduced both of the light samples to my integrating sphere and the comparative spectrum with some data overlay below is the result. I can not vouch for the accuracy but suspect the data is within bounds.
