A light-emitting unit containing a substrate and light emitting diodes (LEDs) is housed inside a casing constituted by a first member and a second member which are joined together. The second member has a projecting piece which is inserted to the first member, and inside the projecting piece a passage is formed. When silicone is injected through an injection opening from an injector, the silicone starting from the projecting piece flows through in the order of the passage, first-member side space, connecting passage and second-member side space and it finally overflows from a discharge opening. By implementing this structure and process, the air or air bubbles inside the light-emitting unit is pushed outside completely.

What is claimed is: 1. A casing, for use with light-emitting unit, that covers over a substrate with light emitting elements mounted thereon, the casing constituted by a first member and a second member which fixedly hold the substrate therebetween and which are approximately dish-shaped and are joined together in a mutually engaged manner such that a hollow area in which the substrate is disposed is formed therebetween, wherein said second member has a projecting piece inserted to said first member and inside the projecting piece there is formed a passage that penetrates from near a top thereof to a bottom thereof so as to communicate the hollow area with the outside of the casing, wherein at a position where the passage is connected to the outside of the casing there is formed an injection opening to inject fluid material to the hollow area via the passage, wherein in the vicinity of the injection opening there is provided a discharge opening to discharge the injected fluid material from the hollow area, wherein, in a state where said second member and said first member are being joined together and mutually engaged therewith, the hollow area is divided into a first-member side space and a second-member side space with the substrate as a boundary therebetween, and a tip of the projecting piece is disposed in the first-member side space whereas the discharge opening is disposed near the second-member side space, and wherein the hollow area is formed in a shape such that the fluid material injected from the injection opening flows from the first-member side space through the second-member side so as to be discharged from the discharge opening. 2. A casing for use with light-emitting unit according to claim 1, wherein said first member is a member positioned in an upper side of the casing for use with light-emitting unit when in use and said first member has a substantially transparent area through which light emitted from the light emitting element transmits and wherein said second member is a member positioned in a back side of the casing for use with light-emitting unit when in use and the injection opening is provided at a position not on the upper side thereof when in use. 3. A casing for use with light-emitting unit according to claim 1, wherein there is provided a concave on an outer surface of the second member and there is provided a discharge opening in part of a bottom face of the concave. 4. A casing for use with light-emitting unit according to claim 2, wherein there is provided a concave on an outer surface of the second member and there is provided a discharge opening in part of a bottom face of the concave. 5. A casing for use with light-emitting unit according to claim 1, wherein the discharge opening is formed in such a manner that an opening area of the discharge opening is larger than that of the injection opening. 6. A casing for use with light-emitting unit according to claim 2, wherein the discharge opening is formed in such a manner that an opening area of the discharge opening is larger than that of the injection opening. 7. A casing for use with light-emitting unit according to claim 3, wherein the discharge opening is formed in such a manner that an opening area of the discharge opening is larger than that of the injection opening. 8. A casing for use with light-emitting unit according to claim 4, wherein the discharge opening is formed in such a manner that an opening area of the discharge opening is larger than that of the injection opening. 9. A casing for use with light-emitting unit according to claim 1, wherein the fluid material is silicone. 10. A casing for use with light-emitting unit according to claim 2, wherein the fluid material is silicone. 11. A casing for use with light-emitting unit according to claim 3, wherein the fluid material is silicone. 12. A casing for use with light-emitting unit according to claim 4, wherein the fluid material is silicone. 13. A casing for use with light-emitting unit according to claim 5, wherein the fluid material is silicone. 14. A casing for use with light-emitting unit according to claim 6, wherein the fluid material is silicone. 15. A casing for use with light-emitting unit according to claim 7, wherein the fluid material is silicone. 16. A casing for use with light-emitting unit according to claim 8, wherein the fluid material is silicone.
