Abstract

In a tubular LED light source individual configurations (4) of light emitting diodes (LED) (6) are confined to a plurality of distinct radial planes distributed with substantial uniform spacing over the length of the tubular bulb portion of the light source. In each configuration a number of light emitting diodes (6) are arranged at a short separation from and with substantial uniform spacing over the inner circumference of the outer wall (1) of the bulb portion, each of said configurations (4) forming individual electrical LED arrays in connection with power supply connectors (3).

Claims

AMENDED CLAIMS
[received by the International Bureau on 01 DEC 2004 (01.12.04); original claims 1 to 12 have been replaced by amended claims 1- 10. 1. A tubular LED light source, comprising a bulb portion having an outer tubular wall (1) of translucent material, a plurality of light emitting diodes (LED) (6) disposed inside said bulb portion with a substantially uniform distribution over the length thereof and over the inside circumference of said outer wall (1) and electrical power supply connectors (3) for said light emitting diodes (LED) (6) , the light emitting diodes (LED) (6) being confined to a plurality of individual LED configurations (4) disposed in distinct radial planes in the bulb portion and each comprising a common support member (5) for a number of light emitting diodes (6) arranged with substantially uniform spacing and at substantially equal separation from said inside circumference of the outer wall (1) of the bulb portion, said configurations (4) forming individual electrical LED arrays in connection with said power connectors (3) , c h a r a c t e r i z e d in that that the common support members (5) of all of said LED configurations (4) are interconnected by a single substantially flat and rigid connection member (8) extending substantially in an axial plan of the bulb portion providing with electrical conductors for said LED arrays.
2. A tubular LED light source as claimed in claim 1, c h a r a c t e r i z e d in that said common support member is formed by a single disk member (5) providing electrical conductors for said num- ber of light emitting diodes (6) , the light emitting diodes being arranged in discrete positions along the circumference of said disk member.
3. A tubular LED light source as claimed in 13
claim 2, c h a r a c t e r i z e d in that said disk member (5) has the form of a substantially regular polygon with a number of sides equal to the number of light emitting diodes (6) in said configura- tion, the light emitting diodes (6) being mounted at individual sides of the disk member (5) .
4. A tubular LED light source as claimed in claim 2 or 3, c h a r a c t e r i z e d in that said disk member (5) is formed by a printed circuit board member providing printed electrical conductors (7) for the light emitting diodes.
5. A tubular LED light source as claimed in any of claim 1, c h a r a c t e r i z e d in that said common support member is formed by a solid member of translucent material encapsulating said number of light emitting diodes (6) .
6. A tubular LED light source as claimed in claim 1, c h a r a c t e r i z e d in that said connection member (8) is a printed circuit board mem- ber providing printed electrical conductors for the
LED arrays .
7. A tubular LED light source as claimed in claim 2 and any of claims 5 or 6, c h a r a c t e r i z e d in that said disk members (5) of the LED configurations (4) are connected with said single connection member (8) with said discrete positions of the light emitting diodes alternating between said radial planes .
8. A tubular LED light source as claimed in any of claims 1 to 7, c h a r a c t e r i z e d in that said LED configurations (4) comprise equal numbers of light emitting diodes (6) ranging from 3 to 15 light 14
9. A tubular LED light source as claimed in any of claims 1 to 8, c h a r a c t e r i z e d in that said LED configurations (4) are disposed with a substantially uniform separation of 15 to 100 mm.
10. A tubular LED light source as claimed in any of claims 1 to 9, c h a r a c t e r i z e d in that said bulb portion is substantially linear and comprises end caps (2) attached to opposite ends of said outer wall (1) , the light source having said power supply connectors disposed in said end caps (2) and being dimensioned and configured to be mounted in a standard fluorescent light tube socket.
