Definitions
- the present invention relates to an illuminating device.
- LED illumination has irreplaceable advan ⁇ tages, such as energy saving, low power consumption, and electrical-to-optical conversion efficiency near to 100%. It can save no less than 80% energy and has a longer service lifetime compared with the traditional light source with the same illuminating efficiency.
- the LED is used more and more as a light source such as a lot of LED retrofit lamps in the market.
- Such LED retro ⁇ fit lamps have the same appearance and profile as the tradi ⁇ tional light source such as incandescent lamp, thus they can be more applicable to the existing illuminating systems as a light source.
- the prior LED retrofit lamp usually has a heat sink, a light engine arranged at one side of the heat sink, a driver hous ⁇ ing and a driver arranged in the driver housing.
- the heat sink forms an accommodation cavity at the other side, and the driver housing is inserted in the accommodation cavity.
- connection modes such as glue bonding, hook or screw joint are usually used in the prior art.
- glue bonding and hook joint it is hard to break up the driver housing and the heat sink without breaking the illuminating device itself.
- the service lifetime of the driver is shorter than that of the LED engine, and the driver should be replaced after the driver fails, for this reason the LED retrofit lamp needs to be disconnected.
- a bulb in the mode of the hook joint, in order to release the connection, a bulb firstly should be removed. But sometimes, the bulb itself is also connected to the heat sink through hook joint or glue bond ⁇ ing, and then the bulb should be broken to contact the hook connection between the driver housing and the heat sink.
- the screw connection between the driver housing and the heat sink obviously increases the number of parts of the LED ret ⁇ rofit lamp, which reduces the assembling efficiency.
- the present invention provides an illuminating device.
- the illuminating device according to the present invention can be simply dissembled without breaking the illuminating device itself, and also has a low cost and a simple structure.
- the object of the present invention is accomplished via an illuminating device.

- the illuminating device according to the present invention uses a special con ⁇ nection structure between the driver housing and the heat sink, and the two can be simply and reliably connected and locked together, or unlocked and disconnected, just by rotat ⁇ ing the driver housing and/or the heat sink.
- Such connection mode avoids the dissembling manner of breaking the illuminat ⁇ ing device itself for removing the driver housing.
- the first rotational locking structure and the second rotational locking structure are configured as structures capable of being locked or unlocked through rotation. Since the driver housing is inserted in the accommodation cavity, an operator can lock and connect the driver housing with the heat sink just by rotat- ing the driver housing or the heat sink in one direction, and can release the locked connection between the driver housing and the heat sink just by rotating the driver housing or the heat sink in the opposite direction, which greatly simplifies the assembling process.
- the first rotational locking structure is config ⁇ ured as internal thread formed in an inner wall defining the accommodation cavity
- the second rotational locking structure is configured as external thread formed on an outer periph ⁇ eral surface of the driver housing and capable of being screwed in the internal thread.
- the internal thread and the external thread can be formed just through a simple process, and the threaded connection can assure more reliable connec ⁇ tion between parts. Besides, such threaded connection struc ⁇ ture does not increase the number of parts of the illuminat- ing device, reducing the manufacturing cost and improving the assembling efficiency.
