LED Lamp Assembly for illuminating room of vehicle

The present invention relates to an LED lamp assembly for a vehicle interior lamp, and more particularly, to a vehicle interior lamp LED lamp assembly that can be used to replace the heat lamp in a vehicle that is to use a double-end cap type heat lamp as an indoor lamp. will be.

As is well known, the interior of a vehicle has at least two lamps for illuminating the interior of the vehicle, e.g. a map lamp which is mounted on the ceiling of the driver's seat and illuminates near the driver's seat, Center lamp and the like are provided. In such a room lamp, a heat transfer lamp that is conventionally illuminated by heat generated by heating a filament has been mainly used. In this heat transfer lamp, two electrodes for supply and demand can be divided into a type disposed side by side on one side of the lamp and a type disposed on both sides. The former type is mainly used as a map lamp for low power, and the latter type is above medium power. It is mainly used as a center lamp. Hereinafter, the latter type is referred to as a double-end cap type.

Figure 1a is a front view showing a conventional double-end cap type lamp, Figure 1b is a perspective view showing the installation state of the center lamp in the interior lights of the conventional vehicle, Figure 1c illustrates the installation structure of the center lamp in the interior lights of the conventional vehicle It is a schematic sectional drawing to make. First, as shown in FIG. 1A, the double-end cap type heat lamp 30 includes a filament 38 housed inside a transparent and vacuum glass tube 36, preferably a cylindrical glass tube 36, Both ends of the filament 36 is provided with a metal supply electrode cap 32 to surround the end of the glass tube 36, the supply electrode cap 32 is also made of a cylindrical shape.

On the other hand, for accommodating such a double-end cap type heat transfer lamp, a supply for holding the two supply electrode caps 32 of the heat transfer lamp 30 in close contact with the ceiling of the vehicle as shown in FIG. 1B. The electrode clips 20 are provided so as to face each other at intervals. To this end, each supply electrode clip 20 is installed to face each other at a predetermined interval, as shown in Figure 1c, but a pair of arc-shaped pieces installed to have a diameter smaller than the diameter of the supply electrode cap 32 as a whole Is done. In FIG. 1B, reference numeral 10 denotes a cover frame of the center lamp.

However, since the conventional heat transfer lamp 30 is made of a filament which is a thin heating wire, the limit lifetime thereof is relatively short, and the brightness of the power consumption is relatively low, and there is a problem in that mass production is difficult.

On the other hand, the use of LED has been limited for displaying the status of various devices in the past, but due to the development of the blue LED and the rapid development of the material field, the use range has recently been extended not only to portable flashlights but also to indoor lighting in houses. . In using such LED as white illumination, the thing which forward-connected the red LED, the green LED, and the blue LED to one chip in series is used. Since the LED is a semiconductor-based light source, the limit lifetime is almost infinite, mass production is easy, and the brightness of the power consumption is improved day by day.

However, when adopting such an LED chip as a vehicle interior light from the beginning, there is no problem, but there is a problem that its application is not easy in a vehicle designed to use a conventional double-end type heat lamp.

The present invention has been made to solve the above-described problems, to provide an indoor lamp LED lamp assembly that can be used to replace the heat lamp in a vehicle that is to use a double-end cap type heat lamp as a lamp for the indoor light. For that purpose.

LED lamp assembly for a vehicle interior light of the present invention for achieving the above object is a printed circuit board printed with various wiring; At least one pair of arc-type supply and demand electrodes provided at intervals on one surface of the printed circuit board, and at least one that is installed on the other surface of the printed circuit board and electrically connected to the supply and demand electrode through the printed wiring of the printed circuit board. Including LED chip.

In the above-described configuration, it is preferable that the printed circuit board is further provided with a bridge diode interposed between the supply electrode and the LED chip to allow the LED chip to operate in a nonpolar manner. On the other hand, each supply electrode may be soldered while being placed on the front of the printed circuit board or through the printed circuit board to be soldered on the back.

According to the LED lamp assembly for a vehicle interior light of the present invention, it is possible to use the LED lamp to replace the heat lamp in a vehicle that is to use a double-end cap type heat lamp as the lamp for the indoor light, and to be brighter with low power almost without replacement The interior of the vehicle can be illuminated.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the LED lamp assembly for a vehicle interior light of the present invention.

2A to 2C are back, front and plan views, respectively, of the LED lamp assembly for a vehicle interior light of the present invention. As shown in Figures 2a to 2c, the LED lamp assembly for a vehicle interior light of the present invention is provided at intervals on one surface of the printed circuit board 110, the printed circuit board 110, the various necessary wiring is printed. One or more pairs of supplying electrodes 140 and the printed circuit board 110 are installed on the other side and at least one electrically connected to the supplying electrode 140 through the printed wiring, in this embodiment six LED chips 160 It can be made, including).

In the above-described configuration, the printed circuit board 110 may be formed of a double-sided printed circuit board, the rear surface 120 is provided with a pair of supplying and receiving electrodes 140 to be held in close contact with the supply electrode clip to be described later. It is fixedly installed, preferably by soldering 170, at an interval equal to that of the electrode clip. On the other hand, since the supply electrode 140 is to replace the supply electrode cap of the heat transfer lamp it may be implemented as an arc-shaped metal piece of the cross section "Ω" shape. And in this case, it is preferable to implement the diameter of the arc-shaped metal piece smaller than the diameter of the supply metal cap of the heat transfer lamp.

As shown in FIG. 3, the LED lamp assembly for a vehicle interior lamp of the present invention may be used as an alternative in a vehicle using a conventional double-end cap type heat lamp. In other words, the conventional double-end cap type heat transfer lamp is separated from the supply electrode clip 20 by simply pushing the supply electrode 140 of the LED lamp assembly of the present invention into the supply electrode clip 20. Can be installed.

Figure 4 is a circuit diagram of an LED lamp assembly for a vehicle interior light of the present invention. Prior to the description, since the conventional double-end type heat transfer lamp operates in a nonpolar manner, it is irrelevant to how the supply electrode clip and the supply electrode are connected. It does not turn on when it is applied. In view of this, in the present invention, in order to operate each LED chip 160 in a non-polarity, the bridge diode (BD) is provided at the front end thereof. In the drawing, reference numeral R denotes a current limiting resistor for limiting a current flowing through each LED chip 160.
