Description

Detachable epoxy LED bulb and its manufacturing method

The present invention relates to an epoxy LED light bulb having a detachable structure and a method of manufacturing the same, and more particularly, a plurality of LED chips are integrally molded with epoxy resin in a glove cap and embedded in a detachable structure provided with a detachable fixing means. The present invention relates to an epoxy LED bulb and a manufacturing method thereof.

Generally, a display element (including general dimmed pushbuttons or dimmed pilot lamps) for indicating whether the power is applied, the operation or state of an electrical component or a mechanical element, including a tungsten filament lamp or LED. A device is used, and in the case of displaying colors other than a single color as a display device of an electronic board, three kinds of lamps or LED display devices of R, G, and B constitute a large number of pixels.

These lamps include a socket holder capable of supporting and lighting them, a down trans for converting an AC power source of 110V or 220V to AC 24V, 6V, etc. And a color globe cap for emitting a predetermined color.

The lamp thus constructed has a good brightness, but is composed of tungsten filament heating wires such as lamps, so that the filament may be damaged due to poor contact with the socket of the lamp, impact voltage at irregular power supply or on / off, or due to prolonged deterioration. Hot wires are often disconnected, requiring frequent exchange.

In addition, the lamp of the glove cap structure of the lamp, the color glow due to the heat generated from the filament heating wire, or the lamp or the glow due to shock or vibration is easily broken or the filament is broken, structurally waterproof, explosion-proof And the like are hardly considered at all.

In addition, since the down transformer is attached to the back of the lamp, not only does the filament deteriorate or the deformation of the glove cap increase due to the heat generated by the down transformer, but also the deterioration or disconnection of the down transformer itself is likely to occur. Repaired or frequently required. In addition, the use of the downtransformation increases the volume of the entire lamp, which makes the handling inconvenient and requires a great deal of strength of the fixing portion for the support.

In addition, the color of the glove cap tends to be discolored and discolored due to light rays, chemicals, or the like, and there is also a problem of preventing the display function of the color from being fulfilled. These problems require considerable manpower, time and cost to manage, repair and maintain numerous lamps.

In consideration of the above-mentioned problems, the LED pilot lamp recently developed uses an LED element instead of the tungsten filament lamp and the like, and the problems caused by deterioration or heat generation of the lamp, etc. have been eliminated. Since the brightness is greatly reduced, the problems of the cap breakage of the glow are also the same, and furthermore, the problems due to the large volume and the problems of waterproofing and explosion proof are not solved.

In addition, the lamp of the display board also has the same problem as above, there is also a problem that the replacement of the LED device is difficult because it is not easy to disassemble and assemble the LED display device as a pixel device.

The present invention is to solve the above-mentioned problems, a plurality of LED chip is integrally molded with epoxy resin in the glove cap is built-in and provides a detachable epoxy LED bulb and a method of manufacturing the detachable structure provided with a detachable fixing means. Its purpose is to.
