Abstract

The utility model relates to the technical field of lamps, and provides a lamp which comprises a shell component and a lighting piece. A base is fixedly arranged in the shell component, the lighting piece is fixedly arranged at one end of the base, a through hole is formed in the base, and a heat conduction tube is fixedly arranged in the position, corresponding to the through hole, at the other end of the base. According to the lamp, the heat conduction tube is arranged on the base in the shell component to enable hot air to pass through the heat conduction tube to be exhausted upward, and meanwhile cold air flow at a low temperature can be absorbed into the shell component and flows through the lighting piece. Thus, heat generated during working of the lighting piece can be discharged in time, and the lighting piece can work at a suitable temperature. The lamp is good in heat dissipation effect, the heat conduction tube is beneficial for prolonging service life of the lamp, and lamp products is high in reliability.

Fig. 1 is the stereogram of the light fixture that provides of the utility model embodiment;

Fig. 2 is the exploded perspective view of the light fixture that provides of the utility model embodiment;

Fig. 3 is the stereogram of pedestal and heat pipe in the light fixture that provides of the utility model embodiment.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As depicted in figs. 1 and 2, a kind of light fixture that the utility model embodiment provides comprises housing unit 100 and illuminating part, and illuminating part can be LED, and its illumination effect is good, and long service life.Certainly, illuminating part also can be bulb etc.Be fixedly installed pedestal 200 in the described housing unit 100, pedestal 200 is used for fixedly illuminating part.Described illuminating part is fixedly installed on an end of described pedestal 200.Be provided with perforation on the described pedestal 200, the corresponding described perforation of the other end of described pedestal 200 place is fixedly installed heat pipe 300, like this, the heat that produces during illuminating part work, it can make the ambient air temperature rise, because the proportion of hot-air is lighter, hot-air can pass perforation and heat pipe upwards flows, and need not to arrange fan, just can make interiors of products form cross-ventilation, reduce illuminating part temperature on every side, improved the radiating effect of product.And, by being fixedly connected with radiating tube at pedestal 200, the area of dissipation of pedestal 200 is increased, further improved radiating effect.

As depicted in figs. 1 and 2, described heat pipe 300 is the hollow form of both ends open, and air-flow can pass heat pipe 300 and realize heat loss through convection, keeps circulation of air, improves radiating effect, has prolonged the life-span.In concrete the application, heat pipe 300 can adopt the copper pipe cutting to form.Certainly, heat pipe 300 also can adopt aluminum pipe or other material to make, and all belongs to protection domain of the present utility model.

As shown in Figure 3, described heat pipe 300 riveted joints or be welded on the described pedestal 200, thermal resistance is little between itself and the pedestal 200, is conducive to improve radiating effect.
