Abstract
The utility model discloses a projection lamp with a multi-chip integrated planar LED light source, which comprises a lamp. The multi-chip integrated planar LED light source, a condensing mirror group and an objective lens are arranged sequentially from the bottom to an outlet in the lamp. After the structural improvement, condensation of the projection lamp can be improved greatly, the generated edge line with light spots is extremely clear, the size of the whole projection lamp can be minimized, cost is reduced and mounting and dismounting processes can be greatly simplified since the LED is highly integrated.
Description
Technical field:
The utility model relates to a kind of projecting lamp that has multicore integrated planar led light source.
Background technology:
The led light source that existing LED projecting lamp uses all is single core, many single-chip LED light sources are set on an installation base plate specifically exactly, adopt the projecting lamp of single-chip LED light source, comprise the layout of single-chip LED and the layout of drive circuit owing to need bigger space to arrange, cause the projecting lamp volume bigger, weight is heavier, and cost is higher, and processing is time-consuming, not easy to assemble, light-emitting area is big, and the hot spot edge line that the light of its ejaculation produces is fuzzy, and its optically focused poor-performing is described.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, the projecting lamp that has multicore integrated planar led light source that provide that a kind of volume is little, cost is low, be easy to install and remove, light-emitting area is little.
For achieving the above object, the technical scheme that the utility model provides is: a kind of projecting lamp that has multicore integrated planar led light source, include light fixture, and in light fixture, from the bottom to the exit, be provided with multicore integrated planar led light source-condenser group-object lens successively.
After said structure improved, the optically focused performance of projecting lamp was greatly improved, and the edge line of the hot spot of generation is very clear, but also can dwindle the volume of whole lamp, reduced cost, because LED by Highgrade integration, can simplify the operation of mounting or dismounting greatly.
Description of drawings:
Fig. 1 is the structural representation of the utility model projecting lamp;
Fig. 2 is the structural representation of the multicore integrated planar led light source in the utility model projecting lamp.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The projecting lamp that has multicore integrated planar led light source of present embodiment includes light fixture 1, is provided with multicore integrated planar led light source 2-condenser group 3-object lens 4 in light fixture 1 from the bottom to the exit successively.Multicore integrated planar led light source 2 is formed by 21 set of a large amount of led chips.
During use,, just can produce the projection effect of height optically focused as long as regulate condenser group and object lens.
The above-mentioned description of this projecting lamp being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
Claims (1)
1. a projecting lamp that has multicore integrated planar led light source includes light fixture, it is characterized in that: be provided with multicore integrated planar led light source-condenser group-object lens in light fixture from the bottom to the exit successively.
