Abstract
The utility model provides a lamp provided with a heat radiation device. The lamp comprises a lamp body, a light emitter, a lamp holder, a PBC (printed circuit board), and the heat radiation device. The heat radiation device is provided with radiating ribs in radial layout along the cross section of the lamp body, and the radiating ribs are uniformly distributed on the bottom of the lamp body. Through utilizing the quick conduction and heat radiation properties of the radiating ribs, the utility model solves the problems of poor thermal conductivity and small radiating area, and has enlarged radiating area, enhanced heat radiation property, lowed temperature in the lamp body, and prolonged service life of the lamp.
Description
Technical field
The utility model relates to a kind of lighting, particularly relates to a kind of lighting with heat abstractor.
Background technology
General existing fitting structure includes fixed lamp-socket, and lead, fixed lamp-socket are to be electrically connected with illuminator, and lead is to be electrically connected with fixed lamp-socket to make the usefulness of power supply.
Because fixed lamp-socket is to be electrically connected with illuminator, so when illuminator was shinny, its luminous power was more and more high, the heat that it produced will be transmitted to fixed lamp-socket, and long-term use may make the temperature of its holder surface increasingly high.But the heat that illuminator produces can't distribute swimmingly, causes the continuous high temperature of light fixture own, makes light fixture be prone to burn damage, has significantly reduced the life-span of light fixture.
Summary of the invention
To above problem, the goal of the invention of the utility model is to overcome existing light fixture thermal diffusivity deficiency, provides a kind of rational in infrastructure, the simple and reliable light fixture with heat abstractor.
A kind of light fixture of the utility model with heat abstractor; It comprises: the truncated cone-shaped lamp body body with hollow structure; With the illuminator that is arranged in this lamp body, said lamp body comprises lamp socket, the PBC plate that is linked in sequence, and also comprises: the heat abstractor that is arranged on this lamp body body outer wall; Said heat abstractor has the heat radiation rib, and this heat radiation rib is along the radial arrangement of lamp body cross section; Said lamp body body bottom surface average mark is furnished with the radiating ribs bar.
Further, described illuminator is a light emitting diode.
Further, said light fixture also comprises the ball alveolitoid cover that is arranged in the said lamp body.
Further, said light fixture also comprises the flame type cover that is arranged in the said lamp body.
Further, said lamp body body bottom surface average mark is furnished with the heat transmission gas hole.
Therefore, the utlity model has following advantage:
After the utility model adopts said structure; Make full use of the fast characteristic of heat abstractor heat loss through conduction, after lamp body was provided with its heat abstractor, area of dissipation was big, the absorption heat is fast, heat dissipation capacity is high, heat dispersion is superior; Applicability is strong; Can reduce the temperature in the lamp body effectively, the protection lamp body improves its service life.

In the present embodiment, described illuminator is light emitting diode (not shown).
In the present embodiment, said light fixture also comprises the ball alveolitoid cover 103 that is arranged in the said lamp body.
Embodiment 2:
See also Fig. 2, Fig. 3, Fig. 4; A kind of light fixture with heat abstractor; It comprises: the truncated cone-shaped lamp body body 402 with hollow structure; With the illuminator (not shown) that is arranged in this lamp body, said lamp body comprises lamp socket 401, the PBC plate (not shown) that is linked in sequence, and also comprises: the heat abstractor that is arranged on this lamp body body outer wall; Said heat abstractor has heat radiation rib 201, and this heat radiation rib is along the radial arrangement of lamp body cross section; Said lamp body body bottom surface average mark is furnished with radiating ribs bar 301.
In the present embodiment, described illuminator is light emitting diode (not shown).
In the present embodiment, said light fixture also comprises the flame type cover 403 that is arranged in the said lamp body.
In the present embodiment, said lamp body body bottom surface average mark is furnished with heat transmission gas hole 302.
According to different cooperations, the difference of its cover, the position that light is flocked together is also different, so the brightness of light is also different, this embodiment 2 has wake flame, and embodiment 1 does not have wake flame.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
