Description

  The present invention relates to a lamp device, and more particularly to a lamp device including a base, a light emitter, and, for example, an inverter type lighting drive circuit for lighting the lamp device, and a lamp unit and a circuit unit that can be detachably combined.

  In recent years, for the purpose of energy saving and the like, lamp devices such as a light bulb type and a compact type fluorescent lamp incorporating an inverter type lighting drive circuit have come to be used in many cases.

This type of fluorescent lamp is described in Patent Document 1, for example. In such a bulb-type or compact fluorescent lamp incorporating a conventional inverter-type lighting drive circuit, the discharge arc tube and the inverter-type lighting drive circuit are integrated. For this reason, replacement of the discharge arc tube that has reached the end of its life is not considered in terms of structure, and the entire fluorescent lamp incorporating the inverter type lighting drive circuit must be replaced.

In this embodiment, the conductive metal fitting 6 is pushed by the connection pin 7 at the time of attachment, but has a spring property that can move in the rotation direction of the lamp portion 2 while keeping the contact by pushing the connection pin 7 back by a repulsive force. Although it is different from the first embodiment in that it is made of a member, the other configurations are the same as those in the first embodiment.

  FIG. 3 is an upper cross-sectional view showing the behavior of the convex portion 13 (14) when the circuit portion 1 and the lamp portion 2 are attached and detached. 4 is an enlarged detailed view of the convex portion 13 (14) and the concave portion 15 (16), (a) is a front view of the convex portion 13 (14) in the direction A in FIG. 1, and (b) is the concave portion 15 (16). It is an A direction front view in FIG. FIGS. 5A and 5B are explanatory views showing the behavior of the convex portions 13 (14) and the concave portions 15 (16) when the circuit portion 1 and the lamp portion 2 are attached / detached. FIG. is there.

  In the circuit unit 1, a single base connected to a power source is an E-type base. For this reason, when the lamp unit 2 is held and the fluorescent lamp is detached from the E-type power base socket 17, the lamp unit 2 attached to the circuit unit 1 may also be detached from the circuit unit in conjunction with it. Therefore, it is desirable that the concave portion 15 (16) engaged with the convex portion 13 (14) is provided with a mechanism for locking the convex portion 13 (14) at the same time as the convex portion 13 (14) is engaged.

  That is, when the lamp part 2 is attached to the circuit part 1, the lamp part 2 is pushed into the circuit part 1 (may be abutted) (FIG. 5 (a-1)), and a lateral rotational force is applied. Thus, the convex portion 13 (14) causes the inclined portion 18 to come into contact with the inclined portion 19 of the protrusion 30 of the concave portion 15 (16) to slide up the inclined portion 19 (FIG. 5 (a-2)), that is, the inclined portion 18. , 19 come into contact with each other and slide to assist the movement in the vertical direction (the longitudinal axis of the lamp), and at the same time, the connection pin 7 is inserted into the groove of the conductive connection fitting 6 (FIG. 1), or the conductive connection fitting with springiness 6 is pushed up (FIG. 2). In the latter case, the conductive conductive metal fitting 6 having a spring property is formed by connecting the connecting pin 7 when the convex portion 13 (14) is dropped into the groove portion 20 of the concave portion 15 (16) (FIG. 5 (a-3)). Then, the convex portion 13 (14) is pressed against the groove portion 20 to be in a fitted state, and at the same time, the convex portion 13 (14) is locked. At this time, since the convex portion 13 (14) is sandwiched between the two vertical surfaces 21 and 22 of the concave portion 15 (16), the lock cannot be released even if the ramp portion 1 is laterally rotated. Thus, the lock mechanism which locks fitting of the convex part 13 (14) and the recessed part 15 (16) via the connection pin 7 with the repulsive force of the conductive connection metal fitting 6 which has a spring property can be comprised. The locking mechanism is not limited to the present embodiment, and another member may be provided instead of the conductive connection fitting to lock the fitting between the convex portion and the concave portion.

When removing the lamp part 2 from the circuit part 1 (FIG. 5B-1), the convex part 13 (14) is pushed into the concave part 15 (16) by pushing the lamp part 2 in the direction of the circuit part 1. Fitting out from the two vertical surfaces 21 and 22 (FIG. 5 (b-2)). At this time, the fitting and locking are released by applying a force in the direction opposite to the lateral rotation applied to the ramp portion 2 during installation. (FIG. 5 (b-3)), the removal is completed by pulling out the lamp unit 2 from the circuit unit 2.
In addition, it is desirable that the inclination angles 23 and 24 of the inclined portions 18, 19 and 19 ′ are less than 90 °. The angles 25 and 26 are desirably 90 °.

  In this way, in the connecting means between the lamp part and the circuit part, the lamp part is pushed into the circuit part when fitted and applied by applying a lateral rotation force, and the lamp part is connected to the circuit part when removed. The fitting can be released by applying a force in the direction opposite to the lateral rotation at the time of attachment to the ramp portion after being pushed into the lamp.
