摘要	A light emission apparatus that can restrict deterioration of resin used for the light emission apparatus, and that has a reasonable structure fit for actual use is provided, in which a light reflective layer is provided to cover the side surfaces of the chips 26 provided in the concave 2a. According to this, excitation light reflected by the phosphor layer 32, such as ultraviolet light, is reflected again by the light reflective layer 27. Therefore, the excitation light will not reach the resin layer 21, thereby restraining the deterioration of the resin. Moreover, the light reflective layer 27 covers the side surfaces of the chips 26, thereby efficiently conducting the heat emitted from the chips 26 to the metal substrate 20 via the resin layer 2 This improves the heat-dissipation efficiency of the chips 26.
其他摘要	本发明提供一种发光装置，其能够限制用于发光装置的树脂的劣化，并且具有适合实际使用的合理结构，其中设置光反射层以覆盖设置在芯片26中的芯片26的侧表面。凹2a。由此，由荧光体层32反射的激发光，例如紫外光，被光反射层27再次反射。因此，激发光不会到达树脂层21，从而抑制树脂的劣化。此外，光反射层27覆盖芯片26的侧表面，从而经由树脂层21有效地将从芯片26发出的热传导到金属基板20.这提高了芯片26的散热效率。
主权项	A light emission apparatus comprising: a substrate that dissipates heat; an insulation film that covers a main surface of the substrate; a metal wiring pattern provided on the insulation film; a light emission chip that is mounted above the insulation film, is connected to the metal wiring pattern, and emits light having a peak wavelength in a range of 250 nm to 480 nm inclusive; and a light reflective layer that is made of particles of metal oxide and is provided at any place that has the insulation film thereunder, but not light emitting surface of the light emission chip thereunder.
