Description
Technical field
The utility model relates to LED down.
Background technology
Existing a kind of LED down is primarily of radiator, substrate, LED, reflector composition, and wherein substrate is established on a heat sink, and LED is located on substrate, and reflector is located in radiator and directly contacts with substrate, and utilizes pressure ring to suppress reflector.Defect existing for the LED down of this structure is: reflector directly and substrate contacts, easily damages substrate and LED by pressure.
Summary of the invention
In order to better protective substrate and LED, the utility model provides a kind of protection type LED down.
For achieving the above object, a kind of protection type LED down, comprise radiator, substrate, LED, reflector, pressure ring, transmissive mirror and spring assembly, radiator has light-source chamber, and substrate is arranged on the bottom of light-source chamber, and LED is located on substrate, reflector is located in light-source chamber, pressure ring is arranged on the opening part of radiator and is compressed on reflector, and transmissive mirror is located in pressure ring, and spring assembly is arranged on pressure ring; Plastic cement casting die is provided with bottom light-source chamber and between reflector; Described plastic cement casting die is provided with accommodating cavity and loophole, and described substrate is positioned at accommodating cavity, and LED is positioned at loophole, and reflector contacts with plastic cement casting die.
Further, plastic cement casting die is positioned at outside accommodating cavity is provided with escape groove.
The beneficial effects of the utility model are: between bottom reflector and light-source chamber, be provided with plastic cement casting die, its plastic cement casting die has accommodating cavity, prevent reflector from directly contacting and damaged substrate and LED with substrate on the one hand, utilize accommodating cavity to be convenient to position installation to substrate on the other hand.In addition, owing to being provided with escape groove, be therefore convenient on the electrode of the substrate that wire is connected through escape groove, to realize being electrically connected.

Fig. 3 is the exploded view at another visual angle of LED down.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1 to Figure 3, LED down comprises radiator 1, substrate 2, LED 3, plastic cement casting die 4, reflector 5, pressure ring 6, transmissive mirror 7, spring assembly 8 and cover plate 9.
As shown in Figures 2 and 3, have light-source chamber 111 in radiator 1, light-source chamber 111 has bottom 112.
Described substrate 2 is arranged on the bottom 112 of light-source chamber.LED installs on a substrate 2.Described plastic cement casting die 4 is provided with accommodating cavity 41 and loophole 42, accommodating cavity 41 is positioned at outside loophole 42, plastic cement casting die 4 is positioned at the escape groove 43 being provided with outside accommodating cavity and communicating with accommodating cavity, described substrate 2 is positioned at accommodating cavity 41, LED 3 is positioned at loophole, and plastic cement casting die 4 is suppressed on a substrate 2 and allowed LED 3 expose.Reflector 5 to be located in light-source chamber 112 and to contact with plastic cement casting die 4.Pressure ring 6 is arranged on the opening part of radiator and is compressed on reflector 5.Transmissive mirror 7 is located in pressure ring 6.
As shown in Figures 2 and 3, spring assembly 8 comprises holder 81, plug-in unit 82, fastener 83, connecting pin 84 and torsion spring 85, holder 81 is located on pressure ring 6, plug-in unit 82 is plugged on holder 81, and fix by screw, fastener 83 is hinged on plug-in unit 82 by connecting pin 84, and torsion spring 85 is enclosed within connecting pin 84, and one end holding is on plug-in unit 82, other end holding is on fastener 83.When installing protection type LED down; pull fastener 83; the upper end of protection type LED down is put into the top of smallpox through the hole of smallpox; then under the effect of torsion spring, fastener 83 resets; utilize the edge clamping of fastener 83 and pressure ring to be held on the edge in smallpox hole, realize the fixed installation to protection type LED down.Cover plate 9 is located in cavity 113.
In the present embodiment, owing to being provided with plastic cement casting die 4 between 112 bottom reflector 5 and light-source chamber, its plastic cement casting die has accommodating cavity 41, prevent reflector 5 from directly contacting and damaged substrate 2 and LED 3 with substrate 2 on the one hand, utilize accommodating cavity 41 to be convenient to position installation to substrate 2 on the other hand.In addition, owing to being provided with escape groove 43, be therefore convenient on the electrode of the substrate that wire is connected through escape groove, to realize being electrically connected.
