Draft specification download
On October 22nd, the EE Times reported that last month, the US Department of Energy ENERGY STAR released its integrated LED lights (which are usually screwed into ANSI standard lamp holders, similar to most incandescent lamps on the market today) Draft revision 3 of the proposed standard. The US Department of Energy's move is to avoid the recurrence of certain negative factors that have affected CFL lamps, thereby ensuring that the LED bulbs with the ENERGY STAR logo are a replacement for existing bulbs accepted by consumers. The new draft incorporates feedback from stakeholders on draft 2.
The following are some of the major changes in draft 3:
Bulb type
Dimmable Lights: Draft 3 requires manufacturers to clearly indicate whether their products are dimming or non-dimming, providing a web page that provides consumers with dimmer compatibility information, and labeling the product packaging to indicate the current There are compatibility limitations that may exist with dimmers.
Non-standard bulbs: “Non-standard†lamps are bulbs that are unusual in shape, size, or size and are used to replace low-voltage incandescent lamps. Draft 3 sets the following requirements for non-standard lights:
Lamp power efficiency requirements
<10 W 50 lm/W
≥10W 55 lm/W
In addition, the minimum illumination requirement for non-standard lamps has dropped from 400 lumens to 200 lumens - roughly equivalent to the illumination of a 25W incandescent lamp. Therefore, the output power of a bulb that meets the minimum output and efficacy requirements will be only 4 watts.
Power factor
Draft 3
• For lamps with power ≤ 5W, no minimum power factor is required
• For lamps with a power >5W, the power factor must be ≥ 0.70
Reliability test
Draft 3 requires that in addition to the fast cycle stress test, the lamp must be tested for lumen maintenance at least 6000 hours at the appropriate temperature. For bulbs with LED packages, modules or arrays (providing LM-80* data), DoE provides a transitional Energy Star certification after 3000 hours of testing.
* The LM-80 is a method approved by the North American Institute of Lighting Engineering (IESNA) to measure the lumen attenuation coefficient of solid state (LED) light sources, arrays and modules.
Minimum service life requirement
The minimum service life requirements have been revised to: a) 15,000 hours for decorative lights, 70% lumen maintenance (L70); b) 25,000 hours for all other types of lamps.
Decorative lights
The following table is the minimum set of light output values ​​and target powers specified in draft 3.
LED decorative light minimum light output requirements
Rated power of the bulb to be replaced (Watt) Minimum light output of the LED bulb (Lumens)
10 70
15 90
25 150
40 300
60 500
Now, DoE is collecting feedback from stakeholders on draft 3, valid until October 16, 2009. Subsequently, DoE plans to release the final draft in early November, with an effective date of August 2010.
