Abstract

A cluster of seven light emitting diodes with their necessary circuitry and current limiting resistors is assembled into a plastic moulding, which in turn is assembled into and connected to a miniature lamp cap. The completed assembly is then filled with a clear epoxy resin. This unit can be used instead of the conventional filament lamp at present fitted in indicators on control panels etc. <IMAGE>

Description

Description A cluster of seven light Emitting Diodes assembled with their necesary circuitry and current limiting resistors into a plastic moulding which is in turn assembled into and connected to a miniature lamp cap. The completed assembly is then filled with a clear epoxy resin.
Use This unit can be used instead of a conventional filament lamp at present fitted in indicators on control panels, machine tools, alarm systems etc.
Advantages The LED cluster has the inbuilt advantage of solid state construction and is therefore unaffected by vibration which would shorten the life of a normal filament lamp.
By having a cluster of LED's it not only increases the light output sufficiently for it to be used in all the standard indicator lamp sizes i.e. 19mm, 22.5mm, 26.5mm and 30.5mm but it also has the safety 'back-up' feature, that it is possible for up to six of the seven LED's to fail and it would still have some form of indication. Naturally it would not be left until this stage was reached before action was taken to replace the unit.
Ease of replacement, the same as replacing a conventional bulb.
Conclusion - Being indicator lamp manufactures it is obvious from experience that there is a need for such a component.
The initial intention is to replace the 6v .30A filament bulb used in transformer lamps, operating on 11 0v, 240v, 440v or 550v 50/60HZ, with this new device. It can of course be designed to work on any voltage either AC or DC.
In the accompanying drawings, the reference numbers indicate the following: 1. LIGHT EMITTING DIODES 2. PLY BOARD 3. TRANSPARENT MOULDING 4. CURRENT EMITTING RESISTORS 5. MINATURE LAMP CAP 6. CLEAR EPOXY RESIN CLAIMS 1. An illuminating device constructed with light emitting diodes fitted in such a manner is a minature lamp holder to make it a direct replacement for a filament lamp with the following advantages: 1. Solid state construction.
2. Long life unaffected by vibration 3. Safety back-up feature, that is one or more light emitting diodes can fail and the remainder will carry on functioning.
New claims or amendments to claims filed on 18.3.82 Superseded claims 1 New or amended claims: CLAIMS 1. An electrical lamp comprising a group of light emitting-diodes and associated current-limiting resistors forming an encapsulated circuit assembly, the lamp further comprising a lamp cap electrically connected to said circuit assembly.
2. A lamp according to claim 1 wherein the light-emitting-diodes project from the encapsulating material.
3. A lamp according to claim 1 or claim 2 wherein an outer casing contains the assembly and its encapsulating material.
4. A lamp according to claim 3 wherein said outer casing is formed by a transparent moulding.
5. A lamp according to any one of claims 1 to 4 wherein said assembly is set in a clear encapsulating material.
6. A lamp according to any one of claims 1 to 5 wherein at least two of the light-emitting-diodes are connected in parallel with each other.
7. A lamp according to any one of claims 1 to 6 wherein the light-emitting-diodes are mounted on a printed circuit board of said assembly 8. A lamp according to any one of claims 1 to 7 wherein the light-emitting-diodes are disposed in a symmetrically arranged cluster as seen from the front of the lamp.
9. A lamp according to any one of claims 1 to 8 having a standard screw cap or bayonet cap connected to said assembly.
10. An electrical lamp constructed and arranged for use substantially as described herein with reference to accompanying drawing.
