Abstract

The invention discloses a light emitting diode (LED) light source device which comprises a substrate, a reflecting cup arranged on the substrate and at least one LED chip which is accommodated in the reflecting cup and is arranged on the substrate. A plurality of groups of sliding chutes are respectively formed in the inner surface of the reflecting cup; and the LED light source device further comprises a fluorescent layer which is selectively inserted into one of groups of the sliding chutes and shields the light emergent direction of the LED chip so as to change the relative distance between the LED chip and the fluorescent layer and further change the emergent light color temperature. According to the LED light source device disclosed by the invention, the sliding chutes are formed in the inner surface of the accommodating cup; and the fluorescent layer is inserted into different sliding chutes, so the distance between the fluorescent layer and the LED chip is changed, the excited efficiency of fluorescent powder in the fluorescent layer is further changed and the adjustment on the emergency light color temperature of the LEDD light source is realized.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a light emitting diode light source device. Background technique [0002] Light-emitting diodes are energy-saving, environmentally friendly, and long-life solid-state light sources. Therefore, the research on light-emitting diode technology has been very active in the past ten years, and light-emitting diodes are gradually replacing traditional light sources such as fluorescent lamps and incandescent lamps. In the prior art, the light emitting diode light source device generally arranges the light emitting diode on the circuit board, and then encapsulates the light emitting diode with an encapsulating gel doped with phosphor powder, and the light emitted by the light emitting diode excites the phosphor powder to emit to the outside of the light source. However, since the position of the phosphor layer after packaging is fixed, the color temperature of the light emitted by the LED light s...
