Panasonic to Release LED Bulbs with Wide Light Distribution Angle of Approximately 300 Degrees
Osaka, Jan 26, 2011 – (JCN Newswire) – Panasonic Corporation today announced that it will release two models of standard type EVERLEDS LED bulbs featuring the wide light distribution angle(1) of approximately 300 degrees on March 18, 2011 in Japan.
Consumers have become increasingly conscious of energy conservation at home, including lighting. LED bulbs are quickly finding their way into homes thanks to their high energy efficiency and long life. However, applications of existing LED bulbs(2) are limited to illuminating spots beneath the lamps because of the bulbs’ narrower light dispersion than incandescent bulbs. Although the existing LED bulbs are suitable for such areas as entrances, bathrooms and staircases, there are demands for LED bulbs that can distribute light at wide angle when used in diffusing panel covered lighting equipments and that can illuminate a broader area.
Panasonic’s new LED bulbs have responded such demands with the two key technologies: “optical design technology that spreads light using a combination of LED packages arranged in a circular pattern inside a large globe and a double reflector structure” and a “high heat dissipation technology with the circuit arranged above the LED packages in order for the circuit parts to be away from the body where the heat converges.” As a result, the new LED bulbs provide the industry’s widest light distribution angle of approximately 300 degrees, which is almost equivalent to the angle of incandescent lamps. The new LED bulbs can replace incandescent bulbs used in light fixtures that help disperse the light throughout the room, giving lighting effects with a light distribution angle almost equal to incandescent light bulbs.
The new E-26 base LED bulbs come in two colors, warm lamp color (LDA7L-G) and daylight color (LDA7D-G) which has brightness equivalent to a 40W(3) incandescent lamp and boast a long service life of 40,000 hours.(4)
Panasonic will strengthen its product lineup with these new bulbs and meet a diverse range of needs to further promote the replacement of traditional incandescent lamps.(5)
(1) A value consistent with the definition of “beam spread” in the Japan Industrial Standards JIS Z8113 “Lighting vocabulary,” and “luminous intensity distribution angle” specified in the Japan Electric Lamp Manufacturers Association Standards JEL 800 “LED Light Bulb Type Code Assignment Method,” in comparison with Silica bulbs
(2) Panasonic LED bulbs, including LDA7L-A1
(3) Indication of the brightness in accordance with the “LED Light Bulb Performance Indication Guidelines 008″ issued by the Japan Electric Lamp Manufacturers Association. Comparison between LDA7D-G and the 40-W tungsten filament lamp for general lighting purposes specified in the Japan Industrial Standards JIS C7501 “tungsten filament lamps for general lighting purposes.”
(4) The rated life is the number of hours of use until the total luminous flux (brightness) becomes 70% of the initial value. The rated life shows an average value and is not guaranteed.
(5) With some fixture types, the lighting performance may not be equivalent to that of incandescent lamps. If the clearance between the LED bulb and the shade of the lighting fixture is narrow, the area around the base may look dark. These LED bulbs cannot be used for fixtures with a dimmer function.
