Discussion on the performance analysis and application of a new type of spherical spherical body light

1 light body structure that is easy to dissipate

1.1 Principle of heat dissipation

The structure of the lamp body is unique, and the heat dissipation is fast. The first lamp holder is vertically below, and the bulb is located in the axial position of the ellipsoidal reflector bowl, so that the hot air is discharged in the Pacific warm current (vertical upward), as shown. The light box and the lens barrel are not on the same optical axis, but are folded at a 90° angle. A fin-shaped Heat Sink is added above the heat filter mirror to effectively discharge most of the infrared rays emitted by the bulb through the heat sink in a vertical upward direction. The radiation is radiated, so that the heat dissipation of the lamp is faster, and the refraction projecting to the lens is a "cold beam" with no heat, as shown. The vertical structure of the lamp holder keeps some key electrical components, namely the lamp holder and the light source, out of the heat flow. This rapid natural heat treatment makes the lamp a veritable "cold beam" luminaire, as shown in 5.

1.2 vertical heat removal effect measured

(1) 6 is the temperature parameter using a 1000W tungsten halogen bulb, and the top temperatures of the three different positions in the figure are 138 ° C, 126 ° C and 105 ° C, respectively. The center of the hole formed by the four imaging stencils, when the distribution curve is taken as the peak, no matter what kind of luminaire does not exceed 225 ° C, and the end of the stencil is only 204 ° C, so the stencil made of stainless steel will not Difficulties in warping or insertion.

1.3 Advantages of the heat dissipation system

(1) Even after long-term use, all manual control parts (such as focus knob, spot adjustment knob, modeling plate, etc.) can maintain a relatively low temperature state.

(2) The temperature of the modeling board is low, and a suitable type of light source can be selected, and even a plastic pattern sheet can be used to project the pattern.

(3) The light source socket and cable are outside the heat flow, which reduces the waste of time caused by maintenance and shutdown due to maintenance.

(4) When the lamp is used in any place, there is no burst noise generated during thermal expansion and contraction.

(5) It is convenient to zoom; it can be adjusted from focus to floodlight, and the stage can be evenly distributed without using a soft film. Selecon's unique bottom (bulb-adjusted central gear) design allows for three-point balance adjustment and smooth adjustment of the bulb position for optimum light distribution.

(6) Use color code to distinguish lens mounting brackets. Easily identifiable with the bulb and lens specifications used, the bracket can be smoothly inserted into the lens barrel without any additional tools and cumbersome assembly.

(7) The lens barrel can be rotated by 360° to facilitate different shapes of cut light and correct pattern projection; (8) Precision optical design achieves optimal light output. Pacific 12 ° ~ 28 °, 14 ° ~ 35 ° and 23 ° ~ 50 ° lamp body, length 635mm, Pacific 5.5 ° ~ 13 ° extremely narrow angle of the body, length 937mm, easy to install and use, take up space small.

(9) Two pattern frame mounting slots: the combination of fixed type and rotary type makes the angle of the graphic change infinite.

(10) Security: Built-in micro-motion contact switch, when the lamp body light source base is removed, the power supply will be automatically cut off to ensure personal safety. All Selecon professional stage lighting adopts the international common three-core lamp tail and electrical safety ground.

The ellipsoidal reflective bowl allows the light output to be changed from peak light distribution (typically 3:1) to flat light distribution (2:1). The peak light distribution does not produce a "strong spot" when the beams overlap, and the flat light distribution is the best light distribution for the projected pattern, as shown in 9.

3 choices, diverse combinations

According to the needs, you can choose the light source configuration suitable for different optical systems. It can be equipped with 600W, 800W, 1000W halogen tungsten foam or 150W, 575W gold halide foam produced by Philips and GE. It can also be connected to a light body with different range, spot and illuminance as needed. 5.5°~13°, 12°~28°, 0Pacific ellipsoidal imaging light can choose different light system light source configuration from peak light distribution to Straight light distribution changes 14° to 35°, 23° to 50°, 45° to 75° dual lens zoom and 5°, 20°, 30°, 40°, 50°, 90° single lens fixed focus Different lamps can be used to obtain different power, beam angle and illumination requirements. The ellipsoid imaging lamp series has many functions, such as 0.

4 "cold light" lamps with different light source configurations

4.1 with halogen light bulb "cold light" lamps

4.1.1 "Cold light" lamps with 600W ~ 1000W halogen tungsten bulbs

The ellipsoidal imaging of a very narrow beam (5.5° to 13°) enhances the performance of high power tungsten halogen lamps. From 220V to 80V, using a switching power transistor (IGBT) electronic transformer and power module, through the thyristor dimmer to adjust the input voltage to 220V full voltage proportionally, using the advantages of low-voltage short filament light source, Increase the utilization of light output.

The advantages of low-pressure bulbs are as follows:

(1) The color temperature of the spot is increased. On the whole spot, half of the new 80V light spot; the other half is the spot of the original 2000W lamp (CP72), both lights are full pressure, compared to the half color of the new lamp is significantly higher than the other half , as shown in 2.

(2) Energy saving. 2000W light fixture replaced by low pressure bubble. When the shooting distance is 30m, the spot diameter can be adjusted from 2.8m to 6.3m, and the satisfactory luminous flux for stage lighting can be obtained. The light source can use 600W, 800W, 1000W halogen tungsten bubble or 150W, 575W gold halide bubble, etc., and the total length of the lamp does not exceed lm, as shown in 1. See Table 1.

(3) A variety of lamps can be used. 80V low-voltage bulbs can be used in a wide range of luminaires, such as 12° to 28°, 23° to 50°, and new 5.5° to 13° variable beam imaging lamps with fixed beam angles of 20°, 30°, 40°, 50 ° and 90° ultra-wide beam imaging lights, etc.

The lamp's high brightness and white characteristics are very attractive, with no characteristic blue and magenta tones of gas discharge sources. The light distribution curve in 3 reflects the change in the photometric characteristics of the lamps used in the three different lamps. Due to the different structure of the filament, the ellipsoidal mirror is matched with the cosine light distribution curve, and the high efficiency of the low-voltage bulb lamp is very obvious.

The illuminance parameters of the ellipsoidal imaging lamps with 80V and 1200W light source are shown in Table 2.

4.1.3 "Cold light" lamps with 575W gas discharge lamps

The optical system of the "Cold Light" series of lamps can be adapted to the MSR575/Z gas discharge lamp with high light output. The lamp is equipped with a hot-start electronic ballast device and a special mechanical shutter. It is controlled by the DMX signal dimming station, and the dimming effect is directly The luminaire that controls the halogen light source with thyristor fades out and fades in, which solves the problem that the gas discharge lamp can not be dimmed, and can be used as a long-range architectural illumination in addition to the high-light-through output for the special scene of the stage.

14 is "cold light" when applying gas discharge lamps

The lamp is equipped with an electronic ballast and a light distribution curve of five different beams. Since the gas discharge lamp has a much higher luminous efficiency than the tungsten halogen lamp (up to 120 Lux/W), it is used for stage or architectural lighting. Much more. Table 3 shows the photoelectric parameters of a 575W gas discharge lamp.

4 is the illumination parameter of Pacific ellipsoidal imaging lamp with 575W gas discharge lamp.

4.1.4 "Cold light" lamps with low-power metal halide lamps

"Cold light" luminaires with single- or double-ended low-power metal halide lamps for architectural lighting.

Ceramic metal halide lamps have a particularly long life span of 9000 to 10,000 hours, and their efficacy is much higher than other bulbs described above. The luminaire can be equipped with an electronic ballast or an inductive ballast. The special mechanical shutter dimming effect is the same as that of a thyristor-controlled halogen source. Table 5 shows the photoelectric parameters of a 150W metal halide bulb.

4.2DMX controlled mechanical shutter

Pacific Series adjustable mechanical shutters are mainly used in imaging lamps such as MSR, MSD and CDM bubble sources. The effect is similar to the fading of a luminaire that directly controls the halogen source with a thyristor. This mechanical shutter solves the problem that the gas discharge light source cannot be dimmed on the stage, such as 5. Its characteristics are as follows: (1) It is suitable for lamps with high color temperature and high light output light source such as MSR, MSD, CDM, etc. The beam fades in and out smoothly.

(2) It has a silent effect and does not require a fan.

(3) Component standard, can be applied to any luminaire in the Pacific series, especially suitable for Pacific ellipsoid imaging concentrating series stage luminaires.

(4) There is no light leakage when the shutter is opened.

(5) Small size.

(6) Use DMX signal control.

(7) Both 100V to 120V and 220V to 240V voltages can be used.

(8) Safe operation, locked with a safety buckle between the Pacific series lamp caps.

5 summary

In summary, the innovative features of the "Pacific" Pacific ellipsoid imaging concentrating series of lamps are summarized as follows:

(1) Modern streamlined appearance structure The lamp body is molded by high-quality aluminum alloy. The lamp body has no sharp edges and corners. It is safe and reliable to use. It is not easy to accumulate dust and easy to remove dirt. The novel lamp body design makes the hot air flow more easily, and the heat dissipation is good, and the external temperature is controlled to the utmost.

(2) Leading optical characteristics The product adopts high temperature resistant silica glass optical lens, which has no defects and special heat treatment, plus excellent focusing coefficient, and emits its low temperature white light beam and beautiful molding line.

(3) Soft slide-type focusing system The system is fast and accurate. Unlike the common focusing system, it has no friction between metals. Due to the special new technology, the focus knob has a good feel. Smooth and tensioned by the tension, the lens is barely felt in the entire focus range, and the filament does not tremble. Even at both ends of the adjustment range, there is no impact phenomenon, which greatly improves the life of the filament. In addition, the scale of the focus scale can be locked, allowing the operator to easily remember the best position for the next use.

(4) Flexible center of gravity balance adjustment mechanism Sometimes it is necessary to replace or adjust, rotate the cutting plate, color changer frame and focus adjustment, which may cause the original position of the lamp to be out of balance, and the Pacific lamp is set in the length direction of the lamp. With the balance fulcrum adjusted, it is easy to restore the balance of the luminaire. If you do not need balance adjustment, you can adjust it and lock it.
