Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1 and Fig. 2, the high brightness tunable optical COB light source that the utility model provides, comprises a plurality of reinforcing pads 3, photochromic light emitting module, high heat radiation carrier 1 and the barricade 2 of a plurality of difference; The photochromic light emitting module of a plurality of differences is all fixed on high heat radiation carrier 1, and barricade 2 is fixed between two adjacent light emitting modules; A plurality of reinforcing pads 3 are all fixed on high heat radiation carrier 1, and different photochromic light emitting modules are electrically connected to from different reinforcing pads 3; Barricade 2 consists of transparent box dam glue.
Compared to prior art, compared with prior art, the high brightness tunable optical COB light source that the utility model provides, be provided with the photochromic light emitting module of a plurality of differences, adjacent light emitting module is separated by transparent barricade 2, and the light that different photochromic light emitting modules send can be irradiated to adjacent one or more light emitting modules by transparent barricade 2; Different photochromic light emitting modules are electrically connected to from different reinforcing pads 3, different photochromic light emitting modules can be electrically connected to external power supply by different reinforcing pads 3, therefore the electric current that can flow through by each light emitting module of independent regulation, independently controls colour temperature and the brightness of each light emitting module.
High brightness tunable optical COB light source of the present utility model, realizes high brightness by the mixed light of a plurality of light emitting modules; By independently controlling colour temperature and the brightness of each light emitting module, regulate colour temperature and the brightness of COB light source.High brightness tunable optical COB light source of the present utility model, lighting angle can reach 160 degree, compared with traditional C OB light source 120 degree, has promoted 25% angle.Of the present utility model simple in structure, production difficulty is low, has economic advantages, is beneficial to and promotes the use of.
The high brightness tunable optical COB light source that the utility model provides, high heat radiation carrier 1 is aluminium base, aluminium oxide ceramic substrate, aluminum nitride ceramic substrate or transparent alumina ceramics substrate.Several high heat radiation carriers 1 have advantages of that good heat dissipation, cost are low above, adopt these high heat radiation carriers 1 can guarantee the thermal diffusivity of lamp, in the useful life of improving lamp, also can reduce production costs.
The first embodiment of the present utility model, in the present embodiment, light emitting module comprises the first light emitting module 4 and the second light emitting module 5; In the first light emitting module 4, be provided with a cavity, the second light emitting module 5 is positioned at cavity; The first light emitting module 4 is just white luminous module, and the second light emitting module 5 is warm-white light-emitting module.The advantage of this structure is, the light of the different colours that two light emitting modules send is mixed light fully, has good light mixing effect.The correlation technique of the first embodiment, can be used for the LED finished product light fixtures such as shot-light, bulb lamp, candle lamp, track lamp, bean pot lamp, floodlight.
