Abstract
The invention discloses a down lamp which comprises a heat dissipation lamp body, fins are arranged on the back surface of the heat dissipation lamp body, each fin is fixedly connected with a fan, the heat dissipation lamp body is connected with a lamp shell, fins and the fan are both arranged in the shell body, a temperature control switch which is used for controlling the fan switch is arranged in the heat dissipation lamp body, and a driving power supply is arranged in the shell body. The down lamp has the advantages of being good in heat dissipation and guaranteeing service life of the down lamp.
Description
Technical field
The present invention relates to a kind of indoor illumination light fitting, particularly a kind of Down lamp.
Background technology
Present commercial or home LED Down lamp, the little heat dispersion that causes of, volume little due to the Down lamp surface area is poor, when LED power is larger, easily causes accumulated heat, shortens LED service life, and more can shorten light fixture service life during more high-power use.
Summary of the invention
The objective of the invention is provides a kind of perfect heat-dissipating in order to overcome above deficiency, guarantees the light fixture Down lamp in service life.
Purpose of the present invention is achieved through the following technical solutions: a kind of Down lamp, comprise heat radiation body, the rear surface of heat radiation body is radiating fin, be fixedly connected with fan on radiating fin, heat radiation body is connected with lamp housing, radiating fin and fan all are placed in lamp housing, are equipped with in heat radiation body for the temperature detect switch (TDS) of controlling fan swicth, are provided with driving power in lamp housing.
The present invention compared with prior art has the following advantages: the Down lamp good heat dissipation effect, the LED chip light decay is little, and the fan of the heat radiation of light fixture compatible conventional and forced heat radiation, fan by the forced heat radiation that is added with at the Down lamp back side when operating temperature is too high is completed heat radiation, when the Down lamp lamp body reaches uniform temperature, control the temperature detect switch (TDS) conducting of fan swicth, fan work; When the lamp body temperature dropped to uniform temperature, temperature detect switch (TDS) disconnected, and fan quits work, and Down lamp is worked in certain temperature range all the time, is conducive to guarantee LED service life.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-lamp housing, 2-fan, 3-heat radiation body, 4-radiating fin.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Show the specific embodiment of a kind of Down lamp of the present invention as Fig. 1, comprise heat radiation body 3, the rear surface of heat radiation body 3 is radiating fin 4, be fixedly connected with fan 2 on radiating fin 4, heat radiation body 3 is connected with lamp housing 1, radiating fin 4 and fan 2 all are placed in lamp housing 1, are equipped with in heat radiation body 3 for the temperature detect switch (TDS) of controlling fan 2 switches, are provided with driving power in lamp housing 1.
Down lamp of the present invention is when operating temperature is too high, the fan 2 of the forced heat radiation that is added with by the Down lamp back side is completed forced heat radiation, when heat radiation body 3 reaches uniform temperature, be contained in the temperature detect switch (TDS) conducting that is used for controlling fan 2 switches in heat radiation body 3, fan 2 work, when heat radiation body 3 drops to uniform temperature, temperature detect switch (TDS) disconnects, fan 2 quits work, Down lamp is worked in certain temperature range all the time, be conducive to guarantee LED service life, simultaneously, lamp housing 1 and heat radiation body 3 are fixed together, play the effect of protection fan 2, and the driving power of Down lamp also is contained in lamp housing 1, the sense of Down lamp one is relatively good, Down lamp good heat dissipation effect of the present invention, the LED chip light decay is little, and the fan 2 of the heat radiation of light fixture compatible conventional and forced heat radiation, when the satisfied heat radiation of the conventional heat radiation energy of ordinary circumstance requires, the fan 2 of forced heat radiation can not start, when routine heat radiation can not be satisfied heat radiation and requires, the fan 2 of forced heat radiation starts, can satisfy the heat radiation requirement like this, again can using electricity wisely.
