Description

LED lens test fixture

Technical Field

The utility model relates to the field of LED lens testing tools, in particular to an LED lens testing tool.

Background

The LED is a semiconductor electronic element capable of converting electric energy into light energy, the LED technology is continuously developed, the application field of the LED is wider, the direct light emitting mode of the LED cannot meet the requirements of numerous fields on the LED illumination effect, in order to adapt to different application scenes, the LED lens is more and more universal, the LED lens can change the light path of LED light and meet the actual use requirements, therefore, a simple LED lens testing tool is necessary to be provided, the lens testing cost is reduced, and meanwhile, the efficiency of artificially testing the lens is improved.

SUMMERY OF THE UTILITY MODEL

The technical problem mainly solved by the embodiment of the utility model is to provide an LED lens testing tool which has the characteristics of simple structure, easiness in assembly and good universality, so that the lens testing cost is reduced, the LED lens testing time is shortened, and the lens screening efficiency is improved, and the technical scheme is adopted for achieving the purpose:

the utility model provides a LED lens test fixture, includes LED light source, lens, still includes base, fixed plate and clamp plate, the base comprises arc body and square body, the base is equipped with the chamber that holds LED light source and lens, it is provided with and holds the chamber bottom and hold the chamber top to hold the chamber, holds the chamber bottom and be the plane, and the plane is seted up the through-hole of placing the power wire to the base surface, holds the chamber top and is concave profile, and concave profile is seted up threadedly.

Furthermore, the lens is placed between the fixing plate and the pressing plate, and silica gel pads are placed between the fixing plate and the lens and between the pressing plate and the lens.

Further, bolt through holes are formed in the fixing plate and the pressing plate, bolt holes are correspondingly formed in the base, and the fixing plate and the pressing plate are assembled with the base through bolts.

The LED lens test tool provided by the utility model has the beneficial effects that:

1. the LED lens testing tool is simple in structure, low in manufacturing cost, easy to assemble and disassemble, time for artificially testing and replacing lenses is shortened, time is saved, efficiency is high, hands of people cannot be cut by the appearance of the arc-shaped body and the base of the square body, the LED lens testing tool is easy to place, through holes for placing wires are formed from the bottom to the outer surface of the base accommodating cavity, the wires and parts cannot interfere when a power supply drives an LED light source, and the light leakage phenomenon during lens testing can be prevented due to the concave surface design of the top of the base accommodating cavity.

2. All through the contact of silica gel pad between fixed plate, clamp plate and the lens, this contact mode can protect lens not receive the damage of external force, reduces the outward appearance flaw, and the spiro union mounting means of each part can effectively solve the not hard up problem of subassembly in the test procedure, reduce test error.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments of the present invention will be briefly described below.

FIG. 1 is an exploded perspective view of the present invention;

FIG. 2 is a top view of the present invention;

FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2;

in the figure:

1. a base; 11. an arc-shaped body; 12. a square body; 13. an accommodating chamber; 14. a through hole; 131. the bottom of the accommodating cavity; 132. the top of the accommodating cavity;

2. an LED light source; 3. a fixing plate; 4. a silica gel pad; 5. a lens; 6. and (7) pressing a plate.

Detailed Description

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.

Refer to FIG. 1 to FIG. 3 a LED lens test fixture, including LED light source 2, lens 5, still include base 1, fixed plate 3 and clamp plate 6, base 1 is formed by arc 11 and square 12 connection, base 1 is equipped with the chamber 13 that holds LED light source 2 and lens 5, hold chamber 13 including holding chamber bottom 131 and holding chamber top 132, it is the plane to hold chamber bottom 131, the bottom plane is the installation face of LED light source 2, it has the through-hole 14 of placing the power wire to the surface to hold chamber bottom 131, can not interfere between wire and part when the power drive LED light source of being convenient for, it is concave profile to hold chamber top 132, concave profile is equipped with the screw thread.

The fixed plate 3 with place lens 5 between the clamp plate 6, contact through silica gel pad 4 between fixed plate 3 and the lens 5, contact through silica gel pad 4 between clamp plate 6 and the lens 5, place after the appearance of silica gel pad 4 can be tailor according to actual need, and this contact mode can protect lens not receive the damage of external force, avoids the outward appearance to have the flaw.

All be equipped with the bolt through-hole on fixed plate 3 and the clamp plate 6, correspond and seted up the bolt hole in base 1, fixed plate 3 passes through the bolt with clamp plate 6 and assembles with base 1, thereby avoids appearing the not hard up problem of part among the test procedure, influences test result and progress.
