Abstract
The utility model relates to the technical field of illumination lamps, and particularly relates to a light engine module capable of convectional heat radiation. The light engine module comprises a radiator, a light source, a reflector and a shell, wherein the reflector is connected with the lower end of the light source and is arranged in the inner cavity of the shell together with the light source; the upper end of the shell is fixedly connected with the radiator; the radiator comprises a plurality of radiating fins and a radiating bottom board; one end of each radiating fin is fixedly connected with the radiating bottom board; a radiating through hole communicated with the inner cavity of the shell is formed in the radiating bottom board; and a plurality of vent holes are formed in the shell. A large amount of heat is generated when the light source gives out light, so that the pressures inside and outside the shell are different; the air inside and outside the shell generates a convection current, so that a part of the heat is radiated out from the vent holes and the radiating through hole; and the other part of heat is radiated out via the radiator. The light engine module is high in heat radiating speed, and the service life of the light engine module can be effectively prolonged.

The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the utility model is further described, the content that embodiment is mentioned is not to restriction of the present utility model.Referring to Fig. 1 to Fig. 2, below in conjunction with accompanying drawing, the utility model is described in detail.
Provided by the utility model
onebut the photo engine module of kind of heat loss through convection, comprise radiator 1, light source 2, reflection shield 3 and housing 4, described radiator 1 is fixedly installed in the upper end of light source 2, described reflection shield 3 is connected with the lower end of light source 2, and light source 2 is installed on the inner chamber of housing 4 together with reflection shield 3, the upper end of described housing 4 is fixedly connected with radiator 1, described radiator 1 comprises some fin 11 and radiating bottom plate 12, one end of described fin 11 is fixedly connected with radiating bottom plate 12, form a heat-dissipating space between two adjacent fin 11, be provided with the heat radiation through hole 13 be communicated with the inner chamber of housing 4 on the corresponding radiating bottom plate 12 of heat-dissipating space, be provided with some air vents 5 on described housing 4.
Because light source 2 can produce a large amount of heat when luminous, cause the inside and outside pressure difference of housing 4, the γ-ray emission convection current that housing 4 is inside and outside, therefore a part of heat can directly distribute from air vent 5 and heat radiation through hole 13, fast dissipation of heat is gone out; Wherein also have another part heat to distribute by radiator 1.Visible radiating rate of the present utility model is fast, can effectively extend the service life of photo engine module.The utility model can assemble the light source 2 of different capacity, and can be applicable to the housing 4 of different size and different size, has good compatibility.
In the present embodiment, described radiating bottom plate 12 is provided with some tapped through holes 14, described housing 4 is provided with corresponding to described tapped through hole 14 places the post 6 that is spirally connected, and described radiating bottom plate 12, by using screw to be fixedly connected with the post 6 that is spirally connected of housing 4, is convenient to installation and maintenance.
