Abstract
The utility model discloses a light-emitting diode support with a parabolic reflector cup, and solves the technical problems that light spots irradiated by a light-emitting diode are centralized and the irradiating distance is increased. The support comprises an inner wall (1) of the parabolic reflector cup and a cup bottom plane (2), and is characterized in that the inner wall of the reflector cup is a paraboloid; and the center of the cup bottom plane is positioned at the focus of the paraboloid. The light rays are reflected by the paraboloid when light-emitting diode fixed in the center of the cup bottom gives out light. Compared with the prior art, the utility model has the advantages of light spot centralization and long irradiating distance.
Description
Technical field;
The utility model relates to the structure of LED support.
Background technology:
Shape is conical in the reflector of existing LED support, and when causing led lighting like this, hot spot can't be concentrated, and irradiation distance is too short.
Summary of the invention:
The purpose of this utility model be to provide a kind of can make lumination of light emitting diode the time hot spot comparatively concentrate and irradiation distance LED support far away.
Technical scheme:
The purpose of this utility model realizes by the following technical solutions; The utility model is made up of parabolic inwall of reflector and cup baseplane, it is characterized in that the reflector inwall for parabolic, the paraboloidal for this reason focus in cup center, the end.Reflector inwall parabola reached the light reflection purpose of optically focused when the center was luminous at the bottom of light-emitting diode chip for backlight unit is fixed in glass.
It is good that the utility model compared with prior art has a spotlight effect, the advantage that irradiation distance is far away.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, the parabolic inwall 1 of reflector, cup baseplane 2, light-emitting diode chip for backlight unit 3 among the figure.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing, as shown in Figure 1, the utility model is a kind of parabolic reflector cup LED support, the center that it is made up of because of cup baseplane 2 parabolic inwall 1 of reflector and cup baseplane 2 is the focus of the parabolic inwall 1 of reflector, so when light-emitting diode chip for backlight unit is fixed on 2 centers, glass baseplane when luminous, the parabolic inwall of reflector reaches the light reflection purpose of optically focused.
Claims (1)
1. a parabolic reflector cup LED support is made up of parabolic inwall (1) of reflector and cup baseplane (2), it is characterized in that the reflector inwall for parabolic, and the center of cup baseplane (2) is on the focus of the parabolic inwall of reflector (1).
