Problems solved by technology

[0004] However, the vehicle lamps developed so far use packaged light-emitting diodes, which not only has the disadvantages of poor production efficiency and high cost, but also has the disadvantage of poor flexibility.
[0005] On the other hand, the light emitted to the lower part of the semiconductor light-emitting element will become a factor that reduces the light quantity of the lamp.

Abstract

The present invention relates to a lamp and, more particularly, to a lamp using a semiconductor light-emitting device, and a method of manufacturing same. The present invention provides the lamp comprising: a substrate; a plurality of semiconductor light-emitting devices disposed on the substrate; a flat layer formed between the semiconductor light-emitting devices; and a spacer disposed between the substrate and the flat layer, in which an air gap is formed between each of the semiconductor light-emitting devices and the spacer.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp using a semiconductor light emitting element and a manufacturing method thereof. Background technique [0002] Vehicles are provided with various vehicle lamps having a lighting function or a signaling function. Generally, a halogen lamp or a gas discharge lamp is mainly used, however, in recent years, a light emitting diode (LED: Light Emitting Diode) has attracted attention as a light source for a vehicle lamp. [0003] As far as light emitting diodes are concerned, not only can the design freedom of lamps be improved by minimizing their size, but they are also economical because they have a semi-permanent life. However, most of them are currently produced in packages. Unpackaged light emitting diodes (LED: Light Emitting Diode) themselves are semiconductor light emitting elements that convert electric current into light, and are being developed as light sources for displaying images in electr...
