Classification of film and television lamps

Film and television lamps can be divided into spotlight, astigmatism lamp and effect light according to the characteristics of their outgoing beams. Generally, it can be divided into three-color lamp, halogen lamp/quartz lamp, HMI, HQI, FRENSEL, LED movie lamp, etc.

Primary colors

Generally speaking, there are two kinds of tricolor lights.

One is an energy-saving light bulb similar to home.

The power varies from 28w to 200w.

Because this kind of energy-saving lamp is energy-saving, with low calorific value, high frequency, accurate color temperature, high brightness and lowest cost, it is most suitable for photographing small commodities or group models.

The brightness of tricolor lamps is generally 26W, which is equivalent to the brightness of 100W incandescent lamps.

The fundamental difference between it and household light bulbs lies in the different color temperatures. The average household color temperature is 6500K, but we generally choose 5000k, 5400k or 5500k white tricolor bulbs. There are many products on the market that sell dog meat by hanging sheep's heads, full of cheap household light bulbs. Due to the high price of color temperature meter, it is recommended to buy well-known products. )

In the early days, there were only two metal covers, which were often used in conjunction with sheds.

Most products of new energy-saving lamps are equipped with various soft boxes or soft cloths. And most of them are high-power light bulbs, and then three, four or even unlimited ones are connected in series. Therefore, the large-scale professional energy-saving lamp studio lamp is also very suitable for taking portraits, especially when a large number of photographers such as exhibitions gather.

For novices, shopkeepers, or friends who often need to hold movie friends' parties, this room light is the best choice.

For this kind of lamp, there are generally visible brands in the market. Opel, Jinbei, Guangbao, U2 and so on.

The better brands abroad are

Baorong Bowens (created many series), Konova (bulb color temperature is particularly accurate, products are very distinctive), Photoflex (with world-class professional guidance), COOLLIGHT (more humanized suit). ) and so on

The other is cathode fluorescent lamp tricolor lamp.

This kind of lamp was originally introduced from movie lights.

It was widely used in small scene lighting when shooting, so it was immediately introduced into the studio market.

The characteristics of this kind of lamp are similar to those of the energy-saving lamp above. Its advantages are brighter fluorescent lamps and more uniform light. The brightness of 100W is about the same as that of an incandescent lamp, and good results can be achieved without soft cloth or simple soft light method.

In addition, the technical difference lies in the rectifier. Generally speaking, imported rectifiers are superior to domestic rectifiers in voltage drop and frequency control.

But if your shooting speed is lower than 1/200, there is little difference between domestic and imported rectifiers.

The main brands in the market are Nanguang and Kooky.

Foreign brands mainly include Konova, Amnova, Keno and ARRI. (Keno and ARRI are very expensive, mainly for filming)

quartz lamp

Halogen lamps have longer life than ordinary bulbs, save electricity 10%-20%, and are small in size.

Quartz lamp is a non-professional name for lamps made of timely glass bulbs, including halogen lamps and other kinds of lamps.

Many common halogen lamps are used as glass shells.

In terms of studio lighting, domestic major manufacturers basically have such products. The power is about1000 w.

It can basically adjust the intensity of light. Can also be equipped with a special soft box.

Red headlights used in other movies and TV shows are also a good choice. Small size, domestic price is cheaper than photography. There are also blades for adjusting the range. Some manufacturers have produced supporting soft boxes.

It is worth mentioning that in some products, halogen lamps are also used to make styling bulbs. For example, some high-end products such as ACE flash and Aurora flash all use 1000w halogen bulbs as styling lamps, and Profoto's high-end outdoor lamps also have 500W styling bulbs. Most of these products have lamp glass covers for adjusting color temperature and heat insulation.

The biggest disadvantage of halogen lamp is its high temperature, which requires the use of metal chuck and special soft box. In addition, the soft box has good heat dissipation, and it is best not to use it for children, which may easily lead to burns.

The color temperature of halogen lamp is about 3200k, which belongs to yellow light, and white light is often used to decorate or set off the atmosphere. Some also want to add special artistic effects.

Almost every family produces this kind of lamp. It should be noted that due to the limited life of halogen bulbs, it is best to buy products of Philips or Osram tubes. In addition, it is best to have a cooling fan or all-metal material in the lamp body.

In China, Meitu, Yongjiang, Opel, Golden Eagle, Kooky, etc.

Man-machine interface lamp

In China, it is called sun lamp, high frequency electroluminescence, electronic dysprosium lamp, dysprosium lamp and spotlight. These lamps are relatively expensive and consume a lot of energy, so they are far from the amateur level.

HQI is relatively cheap and can be widely used, but it has a certain preheating time.

HMI generally has a huge external rectifier (some built-in rectifiers), and the volume changes with the increase of power.

The advantage of their application in the studio is that they can provide a white (5500k) high-frequency and high-intensity light source, which is the most ideal studio lamp at this stage.

To achieve the "what you see is what you get" in professional photography, many friends use this kind of light when shooting cars (especially on location). This kind of lamp is rarely sold in the domestic photography industry.

Led light

This kind of lamp will be the most ideal popular light source for film and television in the future. It has the characteristics of small volume, low cost, high strength and low energy consumption, and the failure rate of LED is low, and the life span of each LED particle is tens of thousands of hours.

In the future, a large part of studio light sources will be replaced by LED lighting. But LED lighting is not very mature. The main reason is that the color temperature of LED particles is difficult to control and the cost is relatively high. It is not mature in the circuit.

In addition, there are few manufacturers, and there are few professional LED movie and television lamps in the market. At present, the relatively mature LED film and television lamp brand in China is Camlight brand, which can be seen in many radio stations and film and television photography. This brand of video lamp is one with better performance.

Camlight was born in 2005, and it is a famous LED professional film and television lamp brand in China. Camlight's products cover camera headlights, scene lights and studio lights, which are widely used in TV studios, film and television crews, news interviews, advertising photography and DV short film shooting.
