Description

A kind of Novel LED down lamp

Technical field

The utility model relates to the illumination optical technical field, particularly a kind of Novel LED down lamp.

Background technology

Semiconductor light-emitting-diode (LED) illuminating product, it is the environmental protection and energy saving product that present country widelys popularize, the LED light fixture has luminous efficiency high, long service life, driving voltage is low, the advantage that fast reaction and power consumption are low, market and application prospect are very wide, wherein the LED Down lamp is as directional light sources, in the place that needs directional lighting, tool has an enormous advantage, and in the use procedure of LED Down lamp, temperature can constantly rise, the long-term insulating properties that the LED Down lamp can occur of at high temperature working are degenerated, the phenomenons such as components and parts damage and material heat ageing, shorten the service life of LED Down lamp, therefore, how effectively the LED Down lamp to be carried out radiating treatment is the important technological problems that industry need to solve.

At present, the LED Down lamp mainly is the shell of being made by aluminium alloy, aluminium base, the LED that is mounted on the aluminium base forms, aluminium base is installed in the enclosure, and be connected with shell, this kind LED Down lamp heat abstractor is the heat conductivility that utilizes aluminium base and shell self, the heat that produces when the LED Down lamp is worked is led away, but because the area of aluminium base is less, cause radiating efficiency not high, and LED Down lamp shell is subject to the restriction of face shaping, and its radiating effect is relatively poor, and the amount of heat that produces in the time of can not in time promptly the LED Down lamp being worked is led away, can not effectivelyly reach the effect of heat radiation, service life is short.

Summary of the invention

Therefore, for above-mentioned problem, the utility model proposes a kind of good heat dissipation effect, the Novel LED down lamp of long service life.

For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of Novel LED down lamp, comprise lamp housing, aluminium base, the LED lamp plate, lens and lens snap ring, described lamp housing is the round table-like of an end opening, described lamp housing not openend is provided with the cylindrical heat-radiating post, the outer circumferential walls of described thermal column is provided with radial fin, the position ring that described lamp housing is positioned at the thermal column periphery is arranged with a plurality of air-vents, described aluminium base is located at the position of pressing close to thermal column in the lamp housing, described aluminium base is provided with the circular hole of mounted LED lamp plate, the edge inwall of described lamp housing openend is provided with at least 3 hole clipping, described buckle and lamp housing geometrical central axis are the central shaft symmetry, described lens snap ring is provided with the buckle corresponding with the hole clipping on the lamp housing, and the buckle of described lens scioptics snap ring and the cooperation of the hole clipping on the lamp housing are arranged in the open end of lamp housing.

Further be: described LED is great power LED.

Further be: also be provided with two on the outer surface of described lamp housing and be the symmetrical supports of 180 degree with the lamp housing geometrical central axis.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the Novel LED down lamp that will design as mentioned above is provided with thermal column, the outer circumferential walls of described thermal column is provided with radial fin, area of dissipation is large, and radiating efficiency is high, and the position ring that described lamp housing is positioned at the thermal column periphery is arranged with a plurality of air-vents, be beneficial to the circulation of air, be convenient to take away a large amount of heats, good heat dissipation effect, long service life, it is poor to have solved the prior art radiating effect, the problem that service life is short.
