Problems solved by technology

[0003] At present, there are some light source devices on the market to solve the above-mentioned problems, but they are all applied in specific scenarios and cannot adapt to the changing on-site environment
Many need to customize special lighting devices and corresponding equipment with the manufacturer according to the specific environment, which is time-consuming and laborious. Therefore, a simple and universal spotlight that can produce a rectangular spot is urgently needed to be developed.

Embodiment Construction

[0013] Such as Figure 1 to Figure 5 A spotlight with a single lens that produces a rectangular spot is shown, including a light source 1, which can be a dot matrix light source 1 (where figure 1 is a schematic diagram of a single dot matrix light source, Figure 5 It is a schematic diagram of two dot matrix light sources; of course, in order to increase the brightness, it can be realized by adding multiple dot matrix light sources) or a linear light source 1, and the scattered light emitted by the light source 1 is arranged at the front of the light source 1 to converge, so that The light emitted by the light source 1 irradiates the illuminated object to form a rectangular light spot (such as image 3 and Figure 4 The symbol shown is the cylindrical light-transmitting mirror 2 of area A). The present invention can increase or decrease the number of light sources 1 according to the specifications of the lamps, so as to achieve ideal effects in practical application.

Abstract

The invention discloses a focus lamp capable of generating rectangular light spots by a single lens, comprising a light source. The focus lamp is characterized in that a cylindrical light-transmitting lens is arranged at the front part of the light source; and the cylindrical light-transmitting lens is used for collecting scattered light sent by the light source and enabling light spots which are formed by illuminating an illuminated object by the light sent by the light source to be the rectangular light spots. The focus lamp of the rectangular light spots has the characteristics of wide application range, intensive light collection, high brightness and less light loss. Furthermore, the focus lamp is convenient to manufacture and low in cost, so that the focus lamp is suitable for wide popularization.

Description

technical field [0001] The invention relates to a light source of a line scan camera, in particular to a spotlight with a single lens producing a rectangular spot. Background technique [0002] As we all know, line scan cameras need to rely on light sources to provide illumination when shooting linear images. High brightness, high efficiency, high uniformity, and flicker-free rectangular light are the requirements of line scan cameras for light sources. The spot area formed by ordinary light sources is large, and the light is not concentrated. However, the present invention uses the principle of light refraction to concentrate the light emitted by the light source to form a rectangular spot, improve the brightness, rationally use the light source, meet the requirements of the line scan camera for the light source, and greatly promote the promotion and application of the line scan camera. [0003] At present, there are some light source devices on the market to solve the abo...
