    • A lighting emitting diode (LED) lamp (100) includes a first LED array (60) and a second LED array (50). A ratio of change of relatively luminous intensity relative to change of temperature of the first LED array is less than that of the second LED array. A first heat sink (10) thermally attaches to the first LED array. A second heat sink (20) thermally attaches to the second LED array. An active heat dissipating device (80) is in combination with the second heat sink for enhancing a heat dissipation efficiency of the second heat sink, and thus the heat dissipation efficiency of the second heat sink is greater than that of the first heat sink. The heat dissipation of the second LED array is much quicker than that of the first LED array. The second LED array thus can be kept working at a much less temperature.
    • 发光二极管(LED)灯(100)包括第一LED阵列(60)和第二LED阵列(50)。 相对于第一LED阵列的温度变化的相对发光强度的变化率小于第二LED阵列的变化率。 第一散热器(10)热连接到第一LED阵列。 第二散热器(20)热附接到第二LED阵列。 主动散热装置(80)与第二散热器组合,用于提高第二散热器的散热效率,因此第二散热器的散热效率大于第一散热器的散热效率。 第二个LED阵列的散热比第一个LED阵列的散热快得多。 因此,第二LED阵列可以在更低的温度下保持工作。

    • An illuminating apparatus (20) includes a lamp cover (200), a solid-state light emitting component (23) and an air tank (24). The lamp cover has a first end and an opposite second end. The lamp cover tapers from the first end to the second end. The lamp cover defines therein an air channel (25) running from the first end to the second end of the lamp cover. The solid-state light emitting component is disposed in the lamp cover at the second end thereof. The air tank has a chamber (240) therein in thermally contact with the solid-state light emitting component. The air tank has a plurality of first and second air vents (244, 245). The chamber is communicated with the air channel via the first air vents, and is communicated with an ambient environment via the second air vents. The first and second air vents are disposed at different altitudes.
    • 照明装置(20)包括灯罩(200),固态发光部件(23)和空气罐(24)。 灯罩具有第一端和相对的第二端。 灯罩从第一端至第二端逐渐变细。 灯罩在其中限定有从灯罩的第一端延伸到第二端的空气通道(25)。 固态发光元件在其第二端设置在灯罩中。 空气罐具有与固态发光部件热接触的室(240)。 空气罐具有多个第一和第二通气孔(244,245)。 该室通过第一通风口与空气通道连通,并通过第二通风口与周围环境连通。 第一和第二通风口处于不同的高度。
