Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of LED module with vertical convection radiator structure that the present invention proposes is described in further detail.
The present invention is directed in prior art because narrow space is airtight, the heat dissipation problem of LED recessed light fixture is comparatively serious, do not become cold-hot air convection passage, even if the problem that the area increasing radiator often also produces little effect, propose a kind of novel settling mode, namely there is the LED module of vertical convection radiator structure.This solution makes LED recessed light fixture still can realize good heat transfer free convection in narrow and small airtight space, enhances radiating effect, is conducive to the weight reducing light fixture simultaneously.
Fig. 2 is the scheme of installation of the embodiment of the present invention, as shown in Figure 2, A-confined space, B-wall, 201-LED module, 202-buckle, 203-cold air, 204-hot-air, wherein, the LED module with vertical convection radiator structure including the embodiment of the present invention is arranged in narrow space confined space A, cold air 203 is converted to hot-air 204 by radiating subassembly formation " stack effect " that LED module comprises and the heat produced by light fixture is taken away, even and then make the LED recessed light fixture containing LED module 201 still can realize good heat transfer free convection in narrow and small airtight space, light fixture is not limited by confined space, produce hot pressing to be formed so-called " stack effect ", enhance radiating effect, be conducive to the weight reducing light fixture simultaneously.
Fig. 3 is the LED modular structure schematic diagram with vertical convection radiator structure of the embodiment of the present invention; As shown in Figure 3, this LED module 201 mainly comprises optical module (2011), substrate (2012), LED light source (2013), radiator (2014), above-mentioned optical module (2011) is fixedly connected with radiator (2014) respectively with substrate (2012), further, also comprise the thermal column (2015) being positioned at radiator (2014) side, vertical convection heat radiation can be formed.Make LED recessed light fixture still can realize good heat transfer free convection in narrow and small airtight space, light fixture is not limited by confined space, still can produce hot pressing, formed so-called " stack effect ", enhance radiating effect, be conducive to the weight reducing light fixture simultaneously.Fixing for substrate 2012 and radiator 2014 of fixed screw 2017 can be comprised in addition, and fixing for optical module 2011 and radiator 2014 of fixed screw 2016.
Fig. 3 is the LED modular structure schematic diagram of the embodiment of the present invention; Fig. 4 is one of LED module generalized section of the embodiment of the present invention; Fig. 5 is the LED module generalized section two of the embodiment of the present invention; Fig. 6 is the optical assembly structure schematic diagram of the embodiment of the present invention.
As seen in figures 3-6, in this programme, the LED module with vertical convection radiator structure has bigger difference with conventional LED recessed lighting fitting, LED light source 2013 is arranged on light fixture edge, the thermal column 2015 arranging up/down perforation in radiator 2014 center, for realizing the heat radiation of light fixture, is namely provided with ventilating opening in radiator 2014 central area.
