Abstract

A load interface capable of saving the cost of installation work is provided. A dummy load generating circuit 13 is built in a radiator 12 integrated with a base 11. By attaching the base 11 to the socket, the load interface 10 can be connected to the dimmer for the incandescent bulb, and the installation work for attaching the load interface 10 to the wall or ceiling can be omitted. Therefore, it is possible to reduce the construction cost when replacing the incandescent bulb with the LED bulb. Further, since the dummy load generating circuit 13 is built in the radiator 12, heat generated during the operation of the load interface 10 is radiated from the radiator 12. For this reason, the durability of the load interface 10 is improved and the risk of ignition of the load interface 10 can be prevented. [Selection] Figure 1

Description

  The present invention relates to a load interface, and more specifically, phase control of electric power from an AC power source is supplied to a light source such as an incandescent bulb or an LED bulb, and the light source is connected to an existing dimmer for dimming. Instead, the present invention relates to a load interface that generates a dummy load so that an existing dimmer operates normally when an LED bulb that consumes less power than a light source is used.

For dimming light sources such as incandescent bulbs and LED bulbs, phase control type dimmers using phase control elements such as triacs are widely used.
For lighting devices equipped with this type of dimmer, remove incandescent bulbs and LED bulbs with high power consumption from the socket, and replace them with LED bulbs with low power consumption to save power and enhance the lighting effect. May be used.

  When using an LED bulb with low power consumption instead of a light source such as an incandescent bulb or LED bulb with high power consumption in a lighting device equipped with a dimmer, the current required for the operation of the existing dimmer does not flow. In particular, when the LED bulb is darkened, the current is further insufficient, and as a result, the LED bulb may flicker during dimming.

  Conventionally, in order to prevent flickering during the dimming of such an LED bulb, a load interface 2 is connected to the existing dimmer 1 later as shown in FIG. The load interface 2 includes a dummy load generation circuit composed of a resistor and an FET, and generates a dummy load so that a required current flows through the existing dimmer 1 by converting the current into heat. Thereby, the flickering of the LED bulb 3 is prevented.

Therefore, when using the LED bulb 3 with low power consumption instead of the incandescent bulb or the LED bulb with high power consumption in order to improve the power saving and lighting effect, there is a problem that the construction cost of the load interface 2 is high.
The present invention has been made in view of such problems, and an object thereof is to provide a load interface that can save the cost of installation work.
