Problems solved by technology

[0003] The air duct structure in the halogen lamp box of the existing color sorter has only two openings: the air inlet and the air outlet; the wind pressure near the halogen lamp far from the air outlet is low, and the air fluidity near the lampshade is poor; at the same time, the air flowing through here The air has passed through several halogen lamps near the air outlet, causing the temperature of the air to rise, which is not conducive to the heat dissipation of the halogen lamps here
The current air duct structure is likely to cause uneven temperature inside the halogen lamp box, showing a gradient change, that is, the temperature near the air outlet of the air duct is low and the temperature near the air inlet is high, resulting in poor temperature consistency

Abstract

The invention provides a lamp box and a color selector. The lamp box comprises a box body, a plurality of lamps, a fan and an air duct; wherein the box body is provided with a closed accommodating space; the plurality of lamps are arranged in the accommodating space in parallel; the fan is arranged in the accommodating space and provided with an air suction opening and an air exhaust opening, andthe air suction opening is communicated with at least the part, occupied by the multiple lamps, of the accommodating space. The air duct is arranged in the accommodating space and is adjacent to the plurality of lamps; the air duct comprises an air inlet and a plurality of air outlets; the air inlet is formed in one end of the arrangement direction of the air duct; the air inlet is communicated with the air outlet, the air outlets are formed in the wall, adjacent to the lamps, of the air duct, the air outlets are adjacent and face the corresponding lamp, the cross section area of each air outlet is smaller than that of the air inlet, and the sum of the cross section areas of all the air outlets is smaller than that of the air inlet. Therefore, the heat dissipation efficiency of each lamp is improved, the temperature consistency, the working stability and consistency of all the lamps are improved, and the temperature uniformity of the box body is improved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a light box and a color sorter. Background technique [0002] In order to reduce the ambient temperature in the halogen light box of the color sorter, major color sorter manufacturers will add air ducts in the halogen light box to dissipate heat through the air cooling cycle to reduce the temperature in the box. The air duct is often designed as a hollow structure with a rectangular cross-section and is constant along the longitudinal direction of the hollow structure. The longitudinal ends of the air duct have an air inlet and an air outlet respectively. [0003] The air duct structure in the halogen lamp box of the existing color sorter has only two openings: the air inlet and the air outlet; the wind pressure near the halogen lamp far from the air outlet is low, and the air fluidity near the lampshade is poor; at the same time, the air flowing through here The air has already passed t...
