Abstract
The utility model discloses a cast light lamp, comprising a support frame, a lamp body, a lamp cover, a water baffle, a lamp socket and a bulb. The utility model is characterized in that the lamp socket is arranged behind a concave mirror reflector, the lamp socket is controlled to move fore-and-aft by an adjustable threaded rod on the lamp body, and the edge of the reflective mirror is provided with a venthole. The bottom of the reflective mirror is provided with a hole which the bulb can pass through. The reflective mirror is positioned on three projections at the opening of the lamp body. The projective beam of the lamp can be concentrated and astigmated as required. The structure of the lamp is applicable to gas convection, improving radiation effect. The utility model has the advantages of small size, light weight, added range of use and flexibility.
Description
The utility model is a kind of light fixture that is used to throw light on, particularly a kind of lighting that is used for the public place.
At present, the Projecting Lamp of selling on the market generally all is made up of support, lamp housing, lampshade, water fender, reflective mirror, lamp socket, bulb etc.The light beam of this Projecting Lamp all is fixing immutable, can not carry out adjusting, the change of astigmatism, optically focused according to actual needs to light beam, and adaptability is not strong; Moreover low power Projecting Lamp, heat dispersion is good inadequately, causes its volume bigger, and weight is heavier, and flexibility is relatively poor.
The purpose of this utility model is to provide a kind of projecting beam can carry out the Projecting Lamp that optically focused, astigmatism are regulated as required, has simultaneously that radiating condition is good, volume is little, in light weight.
The purpose of this utility model is achieved in that the lamp socket of Projecting Lamp is in the back that is paraboloidal concave mirror, control the position that it moves forward and backward by the adjusting screw that is arranged on the lamp housing, the position of bulb in concave mirror can be changed front and back, thereby realize the optically focused of projecting beam, the purpose of astigmatism.The edge that is paraboloidal concave mirror is provided with passage, and its bottom is provided with the hole that bulb can pass through, and is placed on three projections of lamp housing mouth setting, in order to gas flow inside and outside the reflective mirror.Have passage on the lamp housing wall, can make the inside and outside gaseous exchange of lamp housing, thereby reach the raising of radiating effect.
The utility model compared with prior art has following advantage:
1. can control the front and back position of bulb in concave mirror owing to adjusting screw(rod), thereby realize the optically focused of projecting beam, the controllability of astigmatism, can use different projecting beams, make the scope of application of Projecting Lamp and flexibility obtain increasing in different occasions.
2. because this structure is suitable for the circulation of gas, improved its radiating effect, made smaller volume, the weight saving of Projecting Lamp, become more flexible and be suitable for.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the right view of Fig. 1.
With reference to Fig. 1, Fig. 2, lamp housing 2 is fixed on the support 1.The lamp housing mouth is provided with three projections, is equipped with to be paraboloidal concave mirror 6, heat resistant rubber packing ring 9, lampshade 8, briquetting 10, to be fixed on the lamp housing mouth by screw.Be fixed with water fender 7 above the lamp housing mouth.In lamp housing 2, be equipped with lamp socket 4 in reflective mirror 6 back.Reflective mirror 6 edges are provided with a circle passage, and the bottom is provided with the hole that a bulb 5 can pass through.Screw rod 3 is arranged on the back of lamp housing 2, and control lamp socket 4 drives the focus of bulb 5 in reflective mirror 6 and moves forward and backward, and reaches the purpose of optically focused, astigmatism, and this can control light beam and range of exposures.Reflective mirror 6 places on three projections of lamp housing mouth.All there is passage top and bottom at lamp housing 2, and it also has and prevent that rainwater from entering the function of lamp housing 2.Below the lamp housing 2 and have a power line to feed the hole.Lampshade 8 can adopt color cap, and Projecting Lamp is become the colored Projecting Lamp of decoration function.
The utility model is at bulb 5 adstante febres, and the hot gas in the lamp housing 2 just rises, and the orifice flow of hole above lamp housing 2 of process reflective mirror 6 top edges goes out.The passage of cold air below lamp housing 2 flows into, and enters through the lower limb of reflective mirror 6 and the hole of its bottom, produces convection current like this, improved the cooling condition of Projecting Lamp, therefore can make its smaller volume, weight saving.
