電燈放射之光之位置。亦可將直線狀移動與圓弧狀移動組 合，令腕部41呈直線狀移動後再呈圓弧狀移動。 雖說明了將遮蔽部5〇固定於光源裝置之例，但亦可固 定燈資料讀取部45，使移動裝置60移動遮蔽部50，將燈資 13 200816867 料讀取部45收容於隔絕部51内。此時，亦可藉由百葉窗等 來遮蔽燈光。又，可於金屬基部之圓筒部端面22設置可進 入窗部34之凸部以定位，並藉由於其凸部之端面設置燈資 料顯示部45，而可無疑義的決定圓周方向的方位。由於可 5 無疑義的決定圓周方向的方位，因此安裝燈時，可容易使 燈資料顯示部與燈資料讀取部45相對面。又，當為汽缸之 驅動源之高壓力氣體係使用冷卻燈之壓縮空氣時，構成可 變簡單。目前為止係說明具有電極之放電燈之例，亦可應 用於低壓水銀燈、iS素燈、加熱燈、紫外線燈等之其他燈。 ίο 如上所述，本發明之實施例係將遮光源裝置構成為在

The insulating portion 51 is an isolating lamp heat or light (including ultraviolet rays or external lines, the same applies hereinafter), and is applied to the lamp. Fig. 3 is a longitudinal cross-sectional view showing a state in which the lamp data reading unit of the light source device is evacuated to the 15th portion. Fig. 4 is a view showing the lamp data reading portion of the modified example of the light source device being retracted. BRIEF DESCRIPTION OF THE DRAWINGS Next, the function and operation of the light source device according to the embodiment of the present invention constructed as described above will be described. First, the function outline of the light source device will be described with reference to the drawings, in which the metal base support of the light source device is held. The metal base 20 20 of the lamp is shown with light data at the metal base 20 of the lamp. The lamp data is the lamp attribute information and the lamp setting specification information. The display form of the lamp data can be optically read by the reader. When the metal base 20 is held at the metal base support 3, the lamp reading device 40 reads the lamp data. The reading position can be blocked by the metal base = 20, the metal base support 30 and the lamp data reading portion to shield the external light. 200816867 In the 4th, the 4th, the light data master is moved to the retreat position. The retracted position is useful for masking the shielding portion 50 with heat, light 'electromagnetic waves, and high voltage generated when the lamp is lit. After reading the lamp data, control the driving of the lamp and manage the usage status and usage record. 5 Next, the method of reading the lamp data will be described with reference to Fig. 2 . In the lamp data", the member does not. 卩25 and the self% and the recessed portion 44 and the lamp data reading portion Nacheng can be isolated from the C light on the light 54. It can prevent the stray light entering the lamp data reading portion 45 The interference is correctly recognized by the lamp data. The lamp data display unit 25 is optically read and then stored in the lamp data storage device of the light source device. The metal base support holder 30 is provided with the window portion 34 to make the metal base. 20 is not in contact with the wrist portion 41 of the lamp data reading device 40. The notch portion can also be passed through the metal base support holder 30 without providing the window portion 34, and then the lamp reading device 45 reads the lamp material. In the lamp data of the portion 25, the wrist portion 41 of the lamp data reading device 4 has a collision with the metal base portion and the lamp is broken. Further, the lamp is provided by the foreign matter attached to the lamp data display portion 25. In order to avoid this situation, the system and the reading are read by the window portion 34. The lamp data of the discharge lamp can be classified into the properties of each type of discharge lamp and the setting specifications of the discharge lamp. The attributes of the lamp are the date of manufacture, the name of the manufacturer of the discharge lamp, and the manufacturing site. The manufacturing line, the discharge lamp, the plastic type, the type number, the unit number, the identification number, etc., are composed of one or more of them. The discharge lamp is set to a fixed specification lamp current, a fixed specification lamp voltage, The conditions for the use of the discharge lamp in the light source assembly f, such as the cooling conditions, the mounting direction of the device, etc., are combined by one or a plurality of them. The display form of the lamp lean display portion 25 of the discharge lamp is a character, a symbol, a symbol, and 11 200816867 Graphics, simulation, etc. It can also be displayed by a combination of these. It is suitable for bar code or two-dimensional bar code. It can also display the logo of the manufacturing company. The lamp data is based on the difference of the reflectance of light, or the combination of the specular reflection part and the scattering part. In addition to cutting, engraving, engraving, and etching, the lamp data display portion 25 may be formed by laser irradiation or the like. The concave portion may be formed in advance on the end surface of the cylindrical portion of the metal base structure. , the plate on which the lamp data is displayed is embedded and mounted in the recess. Since the lamp data display portion 25 can be visually confirmed, if the user of the discharge lamp is seen If you can understand the text or the graph, you can confirm that the discharge lamp is suitable for the light source pen 10. Next, the method of retracting the lamp data reading unit will be described with reference to Fig. 2 and Fig. 3. Before the lamp housing, As shown in Fig. 2, the lamp data reading unit 45 is inserted into the notch portion 31 of the metal base support base 30 via the arm portion 41 via the arm portion 41 as indicated by the arrow in Fig. 2(A). It is opposed to the material display unit 25 of the lamp 15 via the window portion 34. This position is the reading position of the lamp data. At this position, the lamp data reading unit 45 can read the lamp data display unit 25. Since it is isolated There is no light interference in the light-shielding space 54. Therefore, the lamp data reading unit can correctly read the lamp data, and the read lamp data image signal is subjected to image processing for pattern recognition or character recognition. The characteristics of each type of lamp, such as the setting and specifications of the strict 20 can be taken out as needed. According to this data, π:, π can automatically determine whether the discharge lamp is a discharge lamp suitable for the light source device. If it is a correct discharge lamp, as shown by the arrow in Fig. 3, the wrist portion 41 is moved from the moving device 60, and the lamp data reading portion 45 is retracted to the insulating portion η. When the lamp data item taking portion 45 is retracted to the insulating portion 51, power is supplied to the battery, and 12 200816867 is turned on. In the retracted position, the lamp data reading portion 45 can be isolated from the lamp heat or the light or electromagnetic wave at the time of lighting, and the high voltage applied to the lamp. Therefore, when the lamp is turned on, the lamp data reading unit 45 is moved to the retracted position, and the lamp data reading unit 45 can be prevented from being deteriorated by the heat or light or electromagnetic waves emitted from the lamp and the voltage applied to the lamp 5. The use status of the discharge lamp and the use of the recording can be managed correctly for a long time. On the other hand, if the discharge lamp is not suitable, the lighting is stopped, and a warning is issued to warn that it is an unsuitable lamp. Next, a modification will be described with reference to Fig. 4 . The fourth embodiment (a) is a cross-sectional view showing a state in which the lamp data reading unit is moved and rotated to retreat. The cylindrical arm portion 41 provided with the lamp data reading portion 45 is moved by the moving device 60, and the lamp data reading portion 45 is retracted to a predetermined position. Then, the arm portion 41 is rotated about the axis' so that the lamp data reading portion 45 faces the direction opposite to the lamp. The arm portion 41 is rotated about the axis by the moving device 60, so that the light emitted from the discharge lamp is not incident on the lamp data reading portion 45. By changing only the direction of the lamp data reading unit 45, the shielding portion 50 is not provided, and the light emitted by the discharge lamp does not enter the lamp reading portion 45. It is also possible to retreat only by rotation without moving. Moreover, if it is possible to retreat only to a safe position by movement, it is also possible to evacuate only the movement. 4(B) is a cross-sectional view showing a state in which the wrist portion 41 to which the lamp data reading portion 45 is attached is moved as a crane-like main circle in a solitary state. The arm portion 41 to which the 20-light-lean material reading portion 45 is attached is moved in an arc shape, and is retracted from a position where the light emitted by the lamp can be avoided. It is also possible to combine the linear movement with the circular movement to move the wrist 41 linearly and then to move in an arc shape. Although the example in which the shielding portion 5 is fixed to the light source device has been described, the lamp data reading unit 45 may be fixed, and the moving device 60 may be moved by the shielding unit 50 to accommodate the lamp 13 13 16 16867 material reading unit 45 in the shielding portion 51 . Inside. At this time, the light can be shielded by blinds or the like. Further, the convex portion of the cylindrical portion 34 can be provided on the end surface 22 of the cylindrical portion of the metal base for positioning, and the lamp display portion 45 can be provided by the end surface of the convex portion, whereby the orientation in the circumferential direction can be determined unambiguously. Since the orientation in the circumferential direction can be determined unambiguously, when the lamp is mounted, the lamp data display portion can be easily opposed to the lamp data reading portion 45. Further, when the compressed air of the cooling lamp is used as the high pressure gas system for the driving source of the cylinder, the configuration can be simplified. Heretofore, an example of a discharge lamp having an electrode has been described, and it can also be applied to other lamps such as a low pressure mercury lamp, an iS lamp, a heat lamp, and an ultraviolet lamp. Ίο As described above, the embodiment of the present invention is configured to configure the light-shielding source device to cause the lamp data reading portion to enter the notch portion of the metal base support when reading the lamp data, and to read the lamp data when the discharge lamp is turned on. The pickup portion is retracted from the shielding portion to protect the reading device from deterioration due to heat or voltage. Industrial Applicability 15 The light source device of the present invention is most suitably used as a light source device that can protect a lamp data reading unit provided in a lamp and read lamp data.
