Abstract

The utility model discloses an LED (light-emitting diode) lighting spotlight light source, which comprises an LED light-emitting chip, an LED support, metal silk threads, fluorescent gel and a lens, wherein the LED support is 5.0mm long, 5.0mm wide and 1.0mm high, the lens is 3.5mm high, the diameter of the part, which is combined with the LED support, of the lens is 5.2mm, the surface of the lens is a special cambered light-emitting surface with the top being bulged and the middle being concave. The LED lighting spotlight light source is simple in structure and good in lighting effect, and the problem of uneven light spots can be effectively solved.

Description

A kind of LED illumination reflector lamp light source

Technical field:

The utility model relates to lighting field, relates in particular to a kind of LED illumination reflector lamp light source.

Background technology:

Because the lighting angle of existing conventional planar structure light source is spent left and right 120, if on the lighting of shot-light, use the planar structure light source of this angle can't reach projection, if the light-source angle of 120 degree will be controlled to angle 45 degree of shot-light, that need to increase a secondary lens and use as luminous intensity distribution in the finished product design, because the angle of light source and secondary lens differs very large, so it is lower to allot the light center brightness come, the shot-light radiation response of assembling out is bad, even also there will be the unequal bad defect of hot spot.

The utility model content:

The utility model, in order to solve the prior art problem, provides a kind of LED illumination reflector lamp light source, and it is simple in structure, and radiation response is good, and can effectively solve the problem of hot spot inequality.

The utility model is achieved in that

A kind of LED illumination reflector lamp light source, comprise LED luminescence chip, LED support, tinsel, fluorescent glue and lens, and described LED support is set to long 5.0mm, wide 5.0mm, high 1.0mm; Lens arrange highly as 3.5mm, with LED support junction diameter be 5.2mm, the minute surface of lens is set to the special light-emitting area of top projection central concave curved surface.

The utility model beneficial effect is by the special shape in conjunction with secondary lens and light source contact site, change the structure of LED support and lens, allow more sidelights all with vertical angle, incide in secondary lens and to form optically focused through superrefraction and chip surface light, make light efficiency improve 15%, angle is controlled between the 45-65 degree, radiation response is good, the most important thing is effectively to solve the problem of hot spot inequality.

The accompanying drawing explanation

Fig. 1: be side-looking structural representation of the present utility model.

The specific embodiment

Below in conjunction with legend, the utility model is further described.

As shown in Figure 1, a kind of LED illumination reflector lamp light source, comprise LED luminescence chip 3, LED support 1, tinsel 4, fluorescent glue 5 and lens 6, and described LED support 1 is set to long 5.0mm, wide 5.0mm, high 1.0mm; Lens 6 arrange highly as 3.5mm, with LED support 1 junction diameter be 5.2mm, the minute surface of lens 6 is set to the special light-emitting area of top projection central concave curved surface.

Lens 6 of the present utility model, to be strict with selection and design through light transmission, heat endurance, density, refractive index uniformity, refractive index stability, water imbibition, turbidity, the highest long-term work temperature etc., lamp pearl thickness height overall is 4.5mm, and common SMD lamp pearl thickness is 1.6mm.Increased in the shot-light product that its light gathering of planar light source product after these lens 6 is strong, light efficiency is higher, be applied in illumination coupling more, the parallel incident beam of these lens 6 is through the refraction action of lens Unit 6 simultaneously, form in the horizontal direction symmetrical light diffusion, by adjusting the radius of curvature of lens 6, mix the distribution of irradiating luminous flux in different solid angle scopes, the light that reaches designing requirement distributes, the luminous intensity distribution that so more is conducive to the LED lighting, be particularly suitable for using the shot-light product with the secondary lens luminous intensity distribution.

Claims

1. a LED illumination reflector lamp light source, comprise LED luminescence chip, LED support, tinsel, fluorescent glue and lens, it is characterized in that: described LED support is set to long 5.0mm, wide 5.0mm, high 1.0mm; Lens arrange highly as 3.5mm, with LED support junction diameter be 5.2mm, the minute surface of lens is set to the special light-emitting area of top projection central concave curved surface.
