Abstract

The utility model discloses a high-light LED industrial film viewer with uniform light distribution. The film viewer includes a radiator and a diffuser plate. The film viewer also includes a plurality of LED chips. A U-shaped installation notch is arranged in the center of the diffuser plate. The LED chips are disposed in the notch in an array. The diffuser plate is disposed on the notch flatly. The clearance distance between the LED chip and the diffuser plate is 6 to 16 cm. In the utility model, the LED chips are designed to have the heat dissipation and light distribution functions as a whole. The film viewer is convenient for usage and the appearance of the film viewer is beautiful and ideal heat dissipation effect can be realized. The film viewer using the high-light LED chips are twenty times energy-saving than a traditional film viewer and six to seven times energy-saving than a low-light film viewer. Thus, the energy is effectively saved. And the service lifetime of the LED chips are long. By adopting the LED chips, the service lifetime of the film viewer can reach to 100 thousand hours which is dozens of times of the service lifetime of the traditional film viewer. Thus, the service lifetime of the film viewer is prolonged.

Description

A kind of high-brightness LED industry viewbox of uniform light distribution

Technical field

The utility model relates to industrial detection instrument and field of semiconductor illumination, relates in particular to a kind of high-brightness LED industry viewbox that industrial flaw detection has uniform light distribution that is used for.

Background technology

The industry nondestructive examination relates to industries such as nuclear industry, shipbuilding industry, boiler, the welding of industry steel has crucial effects to above-mentioned enterprise, and the quality of welding is directly connected to the safety of industrial products, especially in inflammable and explosive place, so more need it is carried out quality inspection and evaluation, quality inspection is normally finished by industrial viewbox and experienced slip-stick artist jointly with evaluation.

Weld Quality Inspection is normally carried out X-ray and is taken in the welding position, be imaged on the egative film of photograph, under industrial viewbox, read the sheet analysis by the slip-stick artist then, this and doctor see that the X-ray sheet is very close, the illuminance of reading sheet lamp surface of different is hospital needs only several Luxs, only need visual inspection just can read the sheet analysis, and industrial viewbox surface need 300,000 Luxs to differentiate, and then its quality is distinguished.

Present traditional viewbox has 2 kinds of light-configuration modes: the first is formed with 2000w halogen tungsten fluorescent tube, and the surface just can reach 300,000 lux illumination, is referred to as high illumination viewbox; Another kind of light-configuration mode is the tubule electricity-saving lamp combination with 200w, but this combination can only reach 100,000 lux illumination, if increase fluorescent tube quantity, or increase power, illumination almost can not be risen again, and this is that this class is called the low-light (level) viewbox by the decision of the performance of fluorescent tube.They respectively have relative merits, specifically select according to the blackness of egative film.

Above-mentioned two kinds of industrial viewboxs, domestic have 20,000 being used by each industry part, and annual 10% the speed increase of pressing, the problem that above product exists is: energy consumption big (halogen tungsten lamp series), illumination low (electricity-saving lamp series), life-span short (halogen tungsten lamp 1000 hours, electricity-saving lamp 2000 hours).

The utility model content

The purpose of this utility model is to solve the problems of the prior art, a kind of low energy consumption, long-life is provided, is used for industrial flaw detection, has the high-brightness LED industry viewbox of uniform light distribution.

The technical solution of the utility model is: a kind of high-brightness LED industry viewbox of uniform light distribution, comprise heating radiator and diffuser plate, described viewbox also comprises a plurality of led chips, described diffuser plate center is provided with the U type notch is installed, described led chip array arrangement is in described notch, described diffuser plate is tiled on the described notch, and the clearance of described led chip and diffuser plate is 6～16mm.

Preferably, described led chip is the semiconductor light emitting LED of 120 ° of super brightness.

Preferably, it is 100w that described led chip amounts to 50 general powers, every led chip 140lm/w.

Preferably, apart from being 10mm, fore-and-aft clearance is 4mm to described led chip between left and right.

Preferably, the length of described heating radiator is 400～600mm, and width is 150～250mm.

The beneficial effects of the utility model are: led chip and heat radiation, luminous intensity distribution integrated structure design, easy to use, aesthetic in appearance and reach desirable radiating effect, use high brightness LED chip than energy-conservation 20 times of traditional high illumination viewbox, energy-conservation 6～7 times than low-light (level) viewbox, effectively saved the energy, and the long service life of led chip, whole lamp can reach 100,000 hours, increases by tens times than traditional viewbox, has prolonged the serviceable life of sightseeing sheet.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1: a kind of high-brightness LED industry viewbox of uniform light distribution, comprise LED heating radiator 1 and diffuser plate 2, described viewbox also comprises a plurality of led chips 3, the center of described diffuser plate 2 is provided with the U type notch 21 is installed, described led chip 3 array arrangements are in described notch 21, described diffuser plate 2 is tiled on the described notch 21, and led chip 3 is 6～16mm with the clearance of diffuser plate 2.

Led chip 3 in the utility model adopts the led chip of super brightness, quantity is the best with 50, the led chip of every 140lm/w, its arrangement mode is that rectangular lattice is arranged, each led chip 3 spacing is left and right sides 10mm, longitudinal separation between each led chip 3 is 4mm, led chip 3 is incident upon on the optical window 22 on the diffuser plate 2, led chip 3 can produce 120 ° beam angle, for guaranteeing that 120 ° emergent light can be all and the optical window 22 that is radiated at viewbox, and can reach 0.8 uniformity coefficient.

Diffuser plate 2 is made by the PC material, and in the PC material, added the chemical diffusion agent, the distance of led chip 3 and diffuser plate 2 is adjustable between 6～16mm, guarantee that by above-mentioned condition the illuminance that light decay causes during the mission life of viewbox changes, if less than 6mm, then uniformity coefficient does not reach 0.8, make illuminance higher, if greater than 16mm, uniformity coefficient can reach 0.8, but illuminance is lower than 300,000 luxs, so be chosen between 6～16mm millimeter, above condition makes the general power of viewbox reach 100w, makes optical window can reach 300,000 luxs, has realized the purpose of industrial flaw detection.

As shown in Figure 2, the length of heating radiator 1 is 400～600mm, and width is 150～250mm, and its physical dimension is according to the quantity of led chip 3, and the requirement of industrial flaw detection is reasonably selected.
