Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The utility model provides a can realize radiating lamps and lanterns in narrow space, includes bulb, speculum, heating panel, plastics lamp body and transparent face guard, and the bulb is located the narrow spotlight intracavity that the speculum encloses, is equipped with the heat dissipation breach with spotlight chamber intercommunication on the speculum near the regional lateral wall of bulb filament, and the heating panel is located on the speculum and shutoff heat dissipation breach. The plastic lamp housing covers the reflector and the heat dissipation plate to provide protection, the transparent face shield corresponds to the light outlet of the narrow light gathering cavity, and the transparent face shield is in butt joint with the sealed plastic lamp housing and ensures the light emitting effect. Through setting up heating panel and heat dissipation breach can in time dispel the heat in the speculum, avoid being close to a lateral wall surface of bulb filament region and baked bad. The shape and the area size of the heat dissipation notch can be adjusted adaptively according to actual heat dissipation requirements.

Preferably, the middle part of the heat dissipation plate is provided with a partition groove protruding structure, and the partition groove protruding structure extends into the heat dissipation notch, so that the distance between the heat dissipation plate and the plastic lamp housing can be increased in the area, and the plastic lamp housing in the area is prevented from being baked.
