Abstract
The utility model relates to a parallel cold light source. The utility model comprises a housing, and a high-brightness light-emitting diode lamp is arranged inside the housing; the housing is provided with a lens in the light-emitting direction of the light-emitting diode lamp, and the lens refracts light emitted by the light-emitting diode lamp and makes the light parallelly emitted. The utility model adopts the light-emitting diode lamp as a light source, therefore the utility model has the advantages of small heating value, low temperature and long service life; the lens refracts light rays emitted by the light-emitting diode lamp and then makes the light rays parallelly emitted, and thus a long-distance parallel light source is obtained. The utility model has the advantages of simple structure and easy manufacture and assembly.
Description
Technical field
The utility model relates to the parallel projection light source, particularly a kind of parallel cold light source that uses high brightness LED lamp.
Background technology
Existingly need the equipment of source of parallel light at some, (normally some measurement equipments, for example projecting apparatus, image measurement instrument etc.) makes usually in two ways to obtain source of parallel light.First kind is to use Halogen lamp LED as light source; Second kind is to use a plurality of light emitting diodes (LED) lamp as light source.Simultaneously, cooperate speculum to produce parallel light source.Yet adopt Halogen lamp LED as the shortcoming of light source to be: the heat that produces during Halogen lamp LED work is many, temperature is high, and the heat radiation difficulty, thereby service life is short.Usually only be 1,000 hours the service life of Halogen lamp LED, needs more to change the bulb frequently, uses inconvenience.Adopt a plurality of LED lamps as the shortcoming of light source to be: there is interference in the light that a plurality of LED lamps send, only obtains parallel effect in short distance, can't satisfy the demand of the source of parallel light of longer distance.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of and has than long apart from parallel cold light source source of parallel light, that caloric value is few, simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of parallel cold light source is provided, comprise shell, the LED light lamp of a high brightness is installed, the lens of described shell parallel ejaculation after being equiped with the anaclasis that described LED light lamp is sent on the light direction of described LED light lamp in described shell.
Above-mentioned parallel cold light source, described lens are convex lens or are spherical lens.Described LED light lamp is arranged on the focus of described lens.
The described lens of above-mentioned parallel cold light source are fixed on the described shell by the eyeglass fixed block.
Compared with prior art, parallel cold light source of the present utility model uses LED light lamp as light source, has that caloric value is few, temperature is low, the advantage of long service life; And use parallel ejaculation behind the light refraction that lens make that LED light lamp sends, thereby obtain the source of parallel light of longer distance, have simple in structure, make the processing assembling and be easy to advantage.
Description of drawings
Fig. 1 is the decomposing schematic representation of the parallel cold light source of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing parallel cold light source of the present utility model is described in further detail.
As shown in Figure 1, parallel cold light source of the present utility model comprises shell 11.The LED light lamp 12 of a high brightness is installed in the described shell 11; And can be equiped with circuit board in the described shell 11, perhaps be circumscribed with circuit board, come to light described LED light lamp 12 for described LED light lamp 12 provides power supply.Because use LED light lamp 12 as light source, caloric value is few, temperature is low, the advantage of long service life thereby have.The average life span of LED light lamp 12 reaches 20,000 hours.
Described LED light lamp 12 can be fixed in the described shell by screw 13 or other fixed form.Be equiped with lens 14 on the light direction of described LED light lamp 12, by the refraction action of described lens 14, the light refraction that described LED light lamp 12 is sent becomes parallel light, thereby obtains longer-distance source of parallel light.Described lens 14 can be fixed on the described shell 11 by eyeglass fixed block 15 and screw 13; Certainly, the fixing means of described lens 14 can also be other modes.The parallel cold light source of this structure is simple in structure, makes the processing assembling easily.
In the present embodiment, described lens 14 are convex lens or spherical lens.In order to obtain the better parallel light source, described LED light lamp 12 is placed on the focus of described convex lens or spherical lens.Owing to only use a LED light lamp 12 (being a spot light), thereby only need to calculate the curvature of lens 14, determine the position of LED light lamp 12, can obtain all very good source of parallel light of parallel effect and brightness.
Claims (4)
1, a kind of parallel cold light source, comprise shell, it is characterized in that, the LED light lamp of a high brightness is installed in described shell, the lens of described shell parallel ejaculation after being equiped with the anaclasis that described LED light lamp is sent on the light direction of described LED light lamp.
2, parallel cold light source according to claim 1 is characterized in that, described lens are convex lens or are spherical lens.
3, parallel cold light source according to claim 2 is characterized in that, described LED light lamp is arranged on the focus of described lens.
