Abstract
A light emitting diode (LED) lamp is composed of more than one LED unit in a spliced mode. The LED unit comprises a lamp body, a drive component and a light emitting component, wherein the drive component and the light emitting component are arranged in the lamp body. The light emitting component comprises more than one independently controllable light emitting unit. The light emitting unit comprises an LED substrate, a plurality of independently controllable LED chips arranged on the LED substrate and a light focusing accessory. Due to the fact that each light emitting unit corresponds to the plurality of independently controllable LED chips, self-light-mixing of each light emitting unit is even and luminance is high. Due to the fact that each light emitting unit in the LED unit is independently controllable, light mixing of the LED unit is even and luminance is high. Due to the fact that a light emitting face of the LED lamp is composed of the plurality of LED units, light mixing of the LED lamp is even and luminance is high.
Description
Technical field
The utility model relates to the LED lighting field.
Background technology
All can be provided with the LED substrate in the existing LED light fixture, be located at more than one led chip and the secondary optical lens corresponding with led chip on the LED substrate.The corresponding secondary optical lens of each led chip carries out luminous intensity distribution by secondary optical lens to single led chip, and then carries out mixed light with other led chips.Adopt this mode to carry out the LED light fixture of mixed light, the light that generally mixes out is even inadequately, and luminous brightness is not enough.In addition, the size of existing LED lamp all limits, need the scene of large area light emitting for some, then inapplicable as if the LED light fixture that light-emitting area is less, this often needs to utilize a plurality of LED light fixture splicings just can be effective, Pin Jie large-area light-emitting area mixed light is inhomogeneous like this, and light source is a plurality of hot spots.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED light fixture, even light mixing, luminosity height.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED light fixture, be spliced by more than one LED unit, described LED unit comprises lamp body, is located at driven unit and luminescence component in the described lamp body, described luminescence component comprises separately controllable luminescence unit more than, and described luminescence unit comprises the LED substrate, be located at many separately controllable led chips and optically focused accessory on the described LED substrate.Because corresponding many independent controlled led chips of each luminescence unit, make each luminescence unit self mixed light more even, brightness is higher; Because each luminescence unit in the LED unit is controlled separately, therefore makes the mixed light of LED unit more even, brightness is higher; Because the exiting surface of LED light fixture is made up of a plurality of LED unit, so the mixed light of LED light fixture also becomes evenly and brightness is higher.
As improvement, described optically focused accessory is collector lens or reflector.
As improvement, the led chip in each luminescence unit all is the led chip of solid color or the led chip with multiple different colours.
Spacing between all luminescence units in the LED light fixture equates, makes the bright dipping of LED light fixture more even.
The beneficial effect that the utility model compared with prior art brings is:
Because corresponding many independent controlled led chips of each luminescence unit, make each luminescence unit self mixed light more even, brightness is higher; Because each luminescence unit in the LED unit is controlled separately, therefore makes the mixed light of LED unit more even, brightness is higher; Because the exiting surface of LED light fixture is made up of a plurality of LED unit, so the mixed light of LED light fixture also becomes evenly and brightness is higher.LED light fixture of the present utility model is spliced by a plurality of LED unit, and the size of light fixture can arbitrarily change, and applicability is wider.

The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
Embodiment 1
As shown in Figure 1, a kind of LED light fixture is spliced by more than one LED unit 1, and present embodiment is that example describes with a LED unit 1.Described LED unit 1 comprises lamp body 11, is located at driven unit 3 and luminescence component in the described lamp body 11.Shown in Fig. 3 to 5, described luminescence component comprises separately controllable luminescence unit 2 more than, and the light emitting source assembly of present embodiment comprises that 2, four luminescence units 2 of luminescence unit that four in-lines are arranged can each light separately or all light.Described luminescence unit 2 comprises LED substrate 22, be located at many separately controllable led chips 23 and optically focused accessory 21 on the described LED substrate 22, and the optically focused accessory 21 of present embodiment is reflector.Led chip 23 in each luminescence unit 2 all is the led chip 23 of solid color, and led chip 23 can light separately or all light.After all LED unit 1 splicings, the spacing between all luminescence units 2 equates in the LED light fixture.
Because each luminescence unit 2 corresponding many independent controlled led chips 23, make each luminescence unit 2 self mixed light more even, brightness is higher; Because each luminescence unit 2 in the LED unit 1 is controlled separately, therefore makes the mixed light of LED unit 1 more even, brightness is higher; Because the exiting surface of LED light fixture is made up of a plurality of LED unit 1, so the mixed light of LED light fixture also becomes evenly and brightness is higher.
Embodiment 2
As shown in Figure 2, a kind of LED light fixture is spliced by more than one LED unit 1, and present embodiment is spliced into example with two LED unit 1 and describes.Described LED unit 1 comprises lamp body 11, is located at driven unit 3 and luminescence component in the described lamp body 11.Shown in Fig. 3 to 5, described luminescence component comprises separately controllable luminescence unit 2 more than, and the light emitting source assembly of present embodiment comprises that 2, four luminescence units 2 of luminescence unit that four in-lines arrange can each be bright or all bright separately.Described luminescence unit 2 comprises LED substrate 22, be located at many separately controllable led chips 23 and optically focused accessory 21 on the described LED substrate 22, and the optically focused accessory 21 of present embodiment is collector lens.Led chip 23 in each luminescence unit 2 all is the led chip 23 with different colours, and led chip 23 can light separately or all light.After all LED unit 1 splicings, the spacing between all luminescence units 2 equates in the LED light fixture.
Because each luminescence unit 2 corresponding many independent controlled led chips 23, make each luminescence unit 2 self mixed light more even, brightness is higher; Because each luminescence unit 2 in the LED unit 1 is controlled separately, therefore makes the mixed light of LED unit 1 more even, brightness is higher; Because the exiting surface of LED light fixture is made up of a plurality of LED unit 1, so the mixed light of LED light fixture also becomes evenly and brightness is higher.
