Abstract
A double-ended high intensity discharge lamp includes a luminous tube which comprises an inner tube and an outer tube. At least one electrical member is securely fastened inside the luminous tube and at least one illuminator supported inside the luminous tube with a distributor connected with the electrical member to receive power and supply the illuminator. The outer tube is another protective shield to stop spreading in explosion of the illuminator.
Claims18
A manufacturing method of a double-end high intensity discharge lamp, comprising the steps of:
- A. preparing an inner tube with an inner opening;
- B. melting an outer tube with an outer opening outside said inner tube to define a ventilated channel between said inner tube and said outer tube, wherein said outer tube is formed coaxially around and extended along a length of said inner tube, wherein said outer opening of said outer tube communicates with said inner opening of said inner tube through said ventilated channel;
- C. arranging at least one illuminator supported in said luminous tube, at least one electrical member securely fastened in said luminous tube and at least a distributor connecting said at least one illuminator with said at least one electrical member to receive power and supply said at least one illuminator;
- D. melting to seal two terminals in two sealing ends of said luminous tube respectively;
- E. extracting gas inside said luminous tube through said inner opening, said outer opening and said ventilated channel;
- and
- F. sealing said ventilated channel by sealing at least said outer opening of said outer tube.

A double-ended high intensity discharge lamp, comprising:
- a luminous tube which comprises an inner tube and an outer tube formed coaxially around and extended along a length of said inner tube;
- at least one illuminator supported inside said luminous tube, wherein said luminous tube forms a ventilated channel between said inner tube and said outer tube as a protective shielding adapted to stop spreading in explosion of said illuminator;
- and
- a plurality of electrical members securely fastened in said luminous tube, wherein said electrical members are connected to said illuminator to supply power to operate said illuminator, wherein each of said electrical members further comprises at least two terminals which are permanently fixed in two sealing ends of said luminous tube respectively, wherein said inner tube has an inner opening and said outer tube has an outer opening, wherein said outer opening of said outer tube communicates with said inner opening of said inner tube through said ventilated channel.
