Description

The optics light-emitting device

Technical field

The utility model is about a kind of optics light-emitting device, refers to a kind of optics light-emitting device that is used in street lighting especially.

Background technology

At present, in the existing disclosed correlation technique, as publication number is that 201002990 TaiWan, China patent application " promotes the structure of LED lamp luminescence effect ", its independent claims disclose: to be printed with the aluminium base of the staggered circuit line of rule on the centerablock, offer several screws in the periphery, be installed on this circuit line according to predeterminated position to count the LEDs light emitting diode, and on the LED light emitting diode, respectively cover transparent resin, it is characterized in that:

Cellular reflection shield, it is by the graphic array with respect to the LED light emitting diode, the containing hole permutation and combination identical with many sizes becomes, around each containing hole, be equipped with smooth surface and be a gradient towards on swash plate;

The aspheric surface cloche, it is a curvature lens, extends flanging all around;

Edge, it is to be the hollow ring body that the staged level distributes, and bottom offers through hole, and the upper strata is higher than one section of this bottom;

Therefore, borrowing the curvature lens of aspheric surface cloche to reflect penetrates, to enlarge the scope of light illumination, the surplus light reflection of the LED light emitting diode being sent again by cellular reflection shield, reach total reflection effect through the aspheric surface cloche, and then the reflection ray of getting back to inside reflects again, increase the output quantity of light with this reflection ray of abundant utilization, simultaneously, the partial heat energy conduction dissipation that this LED light emitting diode is sent is also arranged, to be fit to the assembling of various light fixture, the usability again of the light that is reflected is provided, reach the purpose that promotes luminous efficiency.

Though above-mentioned overall structure discloses the swash plate all around of each containing hole that can utilize cellular reflection shield, with the surplus light reflection of the side that holds cover LED light emitting diode within it, to increase the output quantity of light.Yet this said structure tissue, design again with single large-scale aspheric surface cloche two or more LED light emitting diodes that cellular reflection shield and appearance are enclosed within its each containing hole are all covered, make LED light emitting diode and through the swash plate beam reflected, all must see through the aspheric surface cloche again and expand anaclasis, especially all the outer peripheral edges region of guiding aspheric surface cloche from swash plate beam reflected major part, in view of the above, the peripheral surplus photo potential of integrating through the aspheric surface cloche must be more even; But its subsidiary shortcoming that exists is: the light beam that uses this structure to reflect can't be integrated and project in the predetermined angular range, if this structure is used in street lamp, then the surplus light around the aspheric surface cloche will cause the light evil to contiguous household.
