1. Lighting Division

As it is shown on figure 3, according to one embodiment of present invention, Lighting Division 100 includes substrate 110, multiple LED111 of being configured on described substrate 110 and the metallic plate 130 supporting described substrate 110.As LED light source, it is preferred to use LED chip.The LED chip of COB (chiponboard) type can also be used.

Preferred described LED chip is low-power LED chip.As low-power LED chip, it is possible to use the chip of 0.1 watt to 0.6 watt, it is preferred to use the chip of 0.2 watt to 0.5 watt.Low-power LED chip provides identical power in identical area, and compared with the Efficient LED chip that power is higher, the number of the chip of use is more, thus is distributed to make the interval of adjacent chip chamber narrower.

Fig. 1 and Fig. 2 respectively illustrates the Lighting Division of the LED illumination utensil of one embodiment of the invention, specifically, it is shown that the appearance of appearance that multiple low-power LED chips 111 arrange on substrate and multiple Efficient LED chip 111 arrangement.As shown in Figure 1 and Figure 2, use the LED illumination utensil of low-power LED chip in unit are (being designated " A " in the drawings), 5 0.2 watt LED chip (Fig. 1) can be arranged, on the contrary, the LED illumination utensil of Efficient LED chip is used can to arrange 11 watt LED chip (Fig. 2).If this is observed, it is designated the interval between multiple low-power chips of " d1 " in FIG, narrower than the interval being designated in Fig. 2 between multiple high-power die of " d2 ".Although it is not shown in the diagrams, but the LED illumination utensil of the variant embodiment of the present invention, it is possible to according to required design specification and/or customer requirement, in unit are, arrange 10 0.1 watt of LED, 4 0.25 watt of LED chips or 2 0.5 watt of LED chips.
