Description

High-power headlight

Technical Field

The utility model relates to a headlight field, especially a high-power headlight

Background

In the current headlight field, powerful headlight is because lamp source calorific capacity is big, and the shell is integrative infundibulate simultaneously, and the heat radiating area of headlight is not big enough, and a large amount of heats that the lamp source produced can not in time distribute away, leads to the inside temperature of headlight on the high side, and the temperature on the high side can lead to the partial decay of lamp source chip to the luminous performance of lamp source chip has been influenced greatly.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high-power headlight to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a high-power headlamp comprises a frame, a lamp cup and a first shell, and further comprises a fan and a second shell; the frame, the lamp cup, the first shell and the second shell are connected in sequence, the fan is installed at the bottom in the second shell, and the second shell is provided with a power supply interface.

Preferably, the first housing is a ring body, and the cross section of the first housing is a circle gradually decreasing from the front end to the bottom end.

Preferably, the second housing is in a cylindrical shape with an open front end, includes a side wall and a housing bottom, and has a circular cross section gradually decreasing from the front end to the bottom end.

Preferably, the side wall is provided with a plurality of annular ventilation holes, and a plurality of vertically distributed strip-shaped reinforcing ribs are arranged between every two adjacent annular ventilation holes.

Preferably, the shell bottom is provided with a plurality of strip-shaped ventilation holes, and two adjacent strip-shaped ventilation holes are provided with strip-shaped reinforcing ribs perpendicular to the strip-shaped ventilation holes.

Preferably, the frame, the lamp cup and the first shell are made of aluminum alloy materials; the second shell is made of PVC materials.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a fan and the second casing that has a large amount of louvres can in time distribute away the heat that the lamp cup lamp source produced, reduce the decay of lamp source chip as far as possible, make the operation of lamp source chip full load.

Drawings

Fig. 1 is an explosion diagram of the structure of the present invention.

In the figure: 1 frame, 2 rubber rings, 3 lamp cups, 4 first casings, 5 fans and 6 second casings.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a high power head lamp, which includes a frame 1, a rubber ring 2, a lamp cup 3, a first housing 4, a fan 5, and a second housing 6; frame 1, rubber ring 2, lamp cup 3, first casing 4 and second casing 6 are connected gradually, frame 1, lamp cup 3, first casing 4 and second casing 6 cover mutually in proper order and close, fan 5 install in bottom in second casing 6, second casing 6 is equipped with power source. The first shell 4 is a ring body, the cross section of the first shell is a circle gradually reduced from the front end to the bottom end, but the radius of the upper end opening is not greatly different from that of the lower end opening, so that the surface area of the first shell 4 can be increased as much as possible, and heat dissipation is facilitated; the second housing 6 is cylindrical with an open front end, includes a side wall and a housing bottom, and has a circular cross section gradually decreasing from the front end to the bottom end. And its lateral wall is equipped with a plurality of annular ventilation holes, and double-phase adjacent be equipped with a plurality of vertical distribution's bar strengthening rib between the annular ventilation hole, be equipped with a plurality of bar ventilation holes at its bottom of the shell, and double-phase adjacent be equipped with between the bar ventilation hole with bar ventilation hole vertically bar strengthening rib has just so strengthened the heat dissipation function of headlight greatly, and lamp cup 3 and first casing 4 also help the heat dissipation for the aluminum alloy material simultaneously.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
