[detailed description of the invention]
Please refer to shown in Fig. 1 to Fig. 2, the LED 1 of the utility model first preferred embodiment, comprise key lighting chamber 10, be positioned at floor light chamber 12 around key lighting chamber 10 and heat abstractor 13.The main part in key lighting chamber 10 and floor light chamber 12 is positioned at heat abstractor 13 inside, and the light penetrated from floor light chamber 12 is colored.The main part in key lighting chamber 10 and floor light chamber 12 refers to the major part in key lighting chamber 10 and floor light chamber 12, key lighting chamber 10 and floor light chamber 12 only have few part, as outside in not having the parts such as the top of label or illumination cavity 10 to extend heat abstractor 13 for fixing frame 11.It is inner that illumination cavity 10 of the present utility model is positioned at heat abstractor 13, make use of the space of heat abstractor 13 fully, and make area of dissipation larger on the one hand, thermal diffusivity is better, and the illumination cavity 10 of heat abstractor 13 to inside also has certain protective effect on the other hand.The light that floor light chamber 12 is penetrated simultaneously is colored, and the light namely penetrated is not visually white, makes the utility model LED 1 can either increase the diversity of illumination, can play decoration function again.
Key lighting chamber 10 comprises light inlet 101 and light-emitting window 102, floor light chamber 12 comprises light in part 128 and light out part 122, the light-emitting window 102 in key lighting chamber 10 is concordant with the light out part 122 in floor light chamber 12, the light inlet 101 in key lighting chamber 10 and the light in part 128 in floor light chamber 12 are positioned at different planes, the distance of light inlet 101 to the light-emitting window 102 in key lighting chamber 10 is greater than the distance of light in part 128 to the light out part 122 in floor light chamber 12, the distance of the light inlet 101 place plane in light in part 128 to the key lighting chamber 10 in floor light chamber 12 is less than the distance of light in part 128 to the light out part 122 in floor light chamber 12.Because floor light chamber 12 has light source 124, the power of light source 124 is often low than the power of the light source 104 in key lighting chamber 10, therefore the distance arranging light inlet 101 to the light-emitting window 102 in key lighting chamber 10 is greater than the distance of light in part 128 to the light out part 122 in floor light chamber 12, can improve the luminous efficiency in floor light chamber 12.In the present embodiment, the width of the widest part of light inlet 101 is less than the width of the widest part of light-emitting window 102, and the width of light in part 128 the widest part is roughly the same with the width of light out part 122 the widest part.
Heat abstractor 13 comprises base 130 and opening 132, and the base 130 of key lighting chamber 10 self-heat irradiation device 13 of LED 1 extends to opening 132 place, and the middle part of the autonomous illumination cavity 10 in floor light chamber 12 extends to opening 132 place of heat abstractor 13.The middle part in key lighting chamber 10 here does not refer to the middle in key lighting chamber 10, and refers to the position between two ends, key lighting chamber 10.In the present embodiment, base 130 is slightly partial in floor light chamber 12 position from the centre in described key lighting chamber 10 extends, and in other embodiments, the height in floor light chamber 12 and length can adjust as required.
LED 1 also comprises optic panel 14, and optic panel 14 is positioned in the middle part of key lighting chamber 10.In the present embodiment, optic panel 14 is positioned at the middle part in key lighting chamber 10, instead of the light-emitting window 102 in key lighting chamber 10, can also through secondary mixed light after making light pass optic panel 14, and light is evenly soft.In other embodiments, the position of optic panel 14 also can change or not arrange optic panel 14.
LED 1 comprises the first reflecting part 15, second reflecting part 16 and the 3rd reflecting part 17.In the present embodiment, reflecting part 15,16,17 is all as thin-walled configuration.Key lighting chamber 10 comprises the inwall of the first reflecting part 15 and the second reflecting part 16, and floor light chamber 12 comprises outer wall and the 3rd reflecting part 17 of the second reflecting part 16.Key lighting chamber 10 and floor light chamber 12 share the second reflecting part 16, make the structure of LED 1 simpler, compact, cost-saving, be convenient to install.Second reflecting part 16 and the 3rd reflecting part 17 almost parallel, and the second reflecting part 16 and the 3rd reflecting part 17 interval are arranged, and middlely form a cavity.The light source 2824 in floor light chamber 282 is positioned at floor light chamber 12 light in part 128.In the present embodiment, the first reflecting part 15, second reflecting part 16 and the 3rd reflecting part 17 are respectively annular.
In the present embodiment, the first reflecting part 15, second reflecting part 16 and the 3rd reflecting part 17 individually shaping.First reflecting part 15 also comprises and also comprises to the 3rd reflecting part 17 direction connecting portion 152, second reflecting part 16 support portion 160 extended to the 3rd reflecting part 17 direction from the second reflecting part 16 from outer wall, and connecting portion 152 is L-shaped.3rd reflecting part 17 is fixed on connecting portion 152.In the present embodiment, supporting walls 160 is horizontally disposed with, and connecting portion 152 roughly forms a right angle with the junction of supporting walls 160.The light source 124 in floor light chamber 12 is fixed on the supporting walls 160 of the second reflecting part 16.In other embodiments, supporting walls 160 also can for being obliquely installed, and the second reflecting part 16 also can not have supporting walls 160, and light source 124 is between the second reflecting part 16 and the 3rd reflecting part 17.Connecting portion 152 also can be set to other shapes as required, or the first reflecting part 15 also can directly be connected with the second reflecting part 16, one-body molded, and not connected by connecting portion 152.Meanwhile, the light source 124 in floor light chamber 12 also can be fixed on the second reflecting part 16 or the 3rd reflecting part 17 etc.
