The intelligent charging method for the torch enables steady, optimum battery charging, and long service life of the rechargeable battery."Despite its low power consumption, the high efficiency, impact resistant LED lighting technology of the TX40 and TX20 provides a very high luminous intensity," said Klaus Weyer, product line manager Lighting at Cooper Crouse-Hinds.
Does your vendor provide photometric data such as lumens emitted and luminous intensity? If so, ensure they provide you with designed light levels, not initial light levels, recommends Olson.
[4] have dealt with the mathematical modeling problems and have suggested that the slope change of the curve profile is determined by [[tau].sub.i] in the equation and that it has nothing to do with the magnitude of luminous intensity; they also examined the effect of the offset term ([I.sub.0]) in an equation that had been fitted to experimental data for applications and claimed that this term should not occur in a good experimental environment [5].
In order to lighten wood color to the desired brightness level and insure ideal luminous intensity in later stage, hydrogen peroxide ([H.sub.2][O.sub.2]) was employed as bleaching agent in terms of constant temperature bath [10, 11].
The working principle of wireless intelligent control system for HPS lamps and LEDs combined illumination in road tunnel is that the luminous intensity of illumination crucial points in tunnel is detected by intensity detectors installed inside and outside the tunnel.
Luminous Intensity. The measurements of light intensity on the vertical plane were performed by measuring the illuminance produced by the source on a screen placed at 166.2 cm from the photometric centre of the lamp.
Without going into detail, both IES LM-31-95 [IESNA 1995] and LM-35- 02 [IESNA 2002] specify the measurement of luminous intensity distribution using a goniophotometer that is mounted in a large room with black surfaces.
Benchmarked against Energy Star program requirements for integral LED lamps, the Light&Light bulbs offer even luminous intensity and can adapt to omni-directional deployment depending on the arrangement of the LED chips.
(3) Luminance is the luminous intensity (brightness of the light source) per unit area of the light and is represented by cd/m2 (candela per sq.m.).
Another major advantage is that the micromotor allows LED lighting on the contra-angle with the same luminous intensity at both high and low speeds.
Yieh, says the company uses optics technology to optimize lighting fixtures' luminous intensity distribution and patented reflectors to create "area lighting" effect with slim-line light sources.
The Municipal Infrastructure and Assets Sector will also exhibit the General Street Lighting Strategy adopted in Abu Dhabi, which aims at developing a sustainable and long-term lighting policy in order to cut down the economic and environmental costs of excess lighting by modifying the standards of luminous intensity of roads, as well as introducing new energy-efficient lighting techniques with minimal maintenance requirements.
